Definitions
- the present invention relates to machines for manufacturing a material of cushioning / padding from a raw material consisting of an overlay sheets of paper feeding them continuously, by driving and creasing said raw material, then assembly of the assembly crumpled by compressions successive, so as to form a padded band. The latter may then be cut into sections of variable length, as required later.
- these sections of padding material are used in particular for wedge products in cases, cartons, etc. on the one hand in order to prevent them from move inside their packaging, and on the other hand in order to cushion possible shocks applied against said packaging.
- Each machine is generally equipped with at least one electric motor driving the strip of paper to be treated, and more often than not a second motor electric designed to actuate a disconnecting device placed at the downstream outlet.
- US Patent No. 4,619,635 describes such a system assisting in automation, designed using a set of traditional electromechanical means wired and connected to the electric motor ensuring the advancement of the strip of material. These means adjust the period during which the advance motor operates, by selecting said period from a plurality of time periods, so that that the operator no longer has to perform additional operations until the time runs out. The section can then be cut.
- the activation of the cutting means has the additional effect of automatic deactivation of the feed motor, so that the product section is static when cut.
- said motor is not reactivated before a certain period after the actual cutting, in order to allow cutting means to return to their original position.
- the operator actually has adjustment buttons to select a scale (seconds, minutes, hours), then the desired period in the scale chosen. The selection is therefore made only by adjusting the operation.
- the first essential, is that what ultimately matters to the user is the length of tape produced, and that this does not necessarily correspond linearly to a period of advance of the predetermined drive motor.
- the function giving the length produced as a function of time is not linear, for multiple reasons, among which we can cite the quality of the paper, the conditions external (humidity, temperature, ...), etc.
- Machines with an automation system operating by measuring the therefore exhibit significantly different behaviors from each others, without it being possible to guarantee ranges of results for the same machine type.
- the mattress length produced is therefore always guaranteed, whether the whether the motor is slow or fast, whether it operates at 50 Hz or 60 Hz, whether or not it exists hard spots during the advance or at the start (in particular due to the fact that the coil is large or small), etc.
- WO 95/13914 describes a device for measuring the length of the material produced by a machine of the aforementioned type, in the form of a disc placed at the end of a shaft connected to the drive motor, provided on its periphery with a number through holes, and which cooperates with an optical transceiver.
- the disc includes orifices distributed regularly over its periphery, and it is for example painted black, so as not to be reflective.
- the transceiver transmits an axial light signal, which is reflected by a reflector placed in the axis of the transmitter, behind the disc, only when an orifice of said disc passes in face of the transceiver. To each reflection therefore corresponds a reception, which generates a pulse sent to a controller.
- the present invention therefore associates the device placed on the shaft running on specific circuits placed on a central processing unit, performing several particular functions, without which the information collected on the rotating tree would provide incomplete data.
- These functions are not limited to calculations of lengths produced, but make a necessary correction, in order to obtain a measurement of the real length of the fabricated tape.
- the actual linear length adjustment may vary.
- the machine of the invention also comprises a device allowing an operator to control and adjust the correction of the angular length, said device being connected to the central unit of the device electronic correction.
- this device allowing an operator to control and adjust the angular length correction, consists of a keyboard and a display connected to the central processing unit, to transmit the linear length of desired band, as well as a basis for calculating the length correction angular, entered by the keyboard by said operator.
- This basis for calculating the correction is in fact the value of the angular distance corresponding to the production of a unit length of the padded strip. We therefore performs a calibration measurement giving the previous value, which is stores in memory in the central unit.
- the machine can be adapted so that the measured tape output is not the simple horizontal projection of the angular length of the drive wheels.
- the device for measuring the theoretical angular length is a device arranged on a rotating shaft when the strip of material is driven, transforming the angular movement of said shaft into pulses electric.
- said device is an incremental encoder. he is then placed on a shaft driven in rotation when the drive motor of the band is activated.
- Such a machine can be done either in cm or in inches, either using a double track encoder, or using a suitable encoder only for one or the other of said measurement units, proceeding simply installing the encoder suitable for the market in which the machine will run, or by changing the value in memory corresponding to one unit of production length of padded tape.
- Several values can also be stored in several locations in memory.
- the device transforming the angular movement of the shaft electric pulse motor can be an inductive proximity switch operating with at least one metallic element integral with a rotary shaft in movement when the padded band is driven.
- said rotary element is for example of the screw type fixed on a flange a fan integral with the rotary shaft, between the blades of said fan, at a radial distance from the shaft positioning it at each rotation opposite said detector Proximity.
- said rotary element is for example of the screw type fixed on a flange a fan integral with the rotary shaft, between the blades of said fan, at a radial distance from the shaft positioning it at each rotation opposite said detector Proximity.
- the associated central unit comprises a comparator intended to compare on the one hand the number of pulses coming from the device for measuring the angular length traveled, and secondly the number of pulses corrected, and it also includes a means of calculating the number of pulses corrected, by multiplying the desired linear length, input to keyboard by the user, and the correction calculation base, consisting of a number of pulses per linear unit of length.
- the number of pulses corresponding to the length a produce is stored in a particular memory after calculation from two values from an external keyboard accessible to the user, giving on the one hand said length in units of length, and secondly the number of pulses per length unit for a selected raw material quality, depending on the measurement system used (cm or inches), for given operating conditions.
- the device for measuring the padded strip produced adapting to the constraints arising from the operation of the machine and the nature of the raw material used, correctly measures the length of strip produced, due to the existence of the values stored in memory and of a comparator circuit.
- the value of the angular distance traveled by one of said wheels, when the length of the quilted strip produced is equivalent to a unit of length, corresponds to a certain number of pulses, measured then stored or modified in the memory of the central unit when the paper quality and / or the conditions changes.
- the basic system allowing the folding of the longitudinal edges of the strip multilayer appears more particularly in Figures 1 and 2, from the paper of the reel 2 and in particular thanks to a guide system ensuring the folding of the edges longitudinal in a simple and efficient way.
- This guidance system mainly comprises a central plate 33 of shape substantially horizontal, around which the strip of paper M is wound, by folding the longitudinal edges towards the scroll axis, guided in this by the wheels 31 and the metal rods 32, according to a configuration already known.
- Encoder c the first example illustrated, is mounted on the assembled mechanical assembly in cradle 4, the various elements and arrangement of which are shown in figures 3-4.
- This set includes a first pair of superimposed wheels ( Figure 3), know a top wheel or drive wheel 8 rotating on an axis 9 mounted in the lateral flanges 10-10 ′ of the cradle 4, and a lower support wheel 11, rotating on an axis 12 carried by lifting beams 13, 13 'elastically mounted tilting relative to cradle 4, as described in more detail in the Patent EP-A-0679 504 of the applicant.
- the same mechanical assembly includes a second pair of wheels superimposed (FIG. 4), namely an upper wheel or compression wheel 14, rotating on an axis 15 mounted in the lateral flanges 10, 10 'and driven in rotation by the motor 5, and a lower support wheel 17, rotating on an axis 18 also carried by the lifting beams 13, 13 'mounted resiliently tilting by relative to the cradle 4 via springs 26, 26 '.
- a second pair of wheels superimposed FIG. 4
- an upper wheel or compression wheel 14 rotating on an axis 15 mounted in the lateral flanges 10, 10 'and driven in rotation by the motor 5
- a lower support wheel 17 rotating on an axis 18 also carried by the lifting beams 13, 13 'mounted resiliently tilting by relative to the cradle 4 via springs 26, 26 '.
- the two axes 9 and 15 are positively driven by the motor 5, namely the axis 15 directly and the axis 9 via a gear train shown schematically in 16 a , 16 b , 16 c between FIGS. 3 and 4.
- the incremental encoder c is mounted on the axis 15, at the other end relative to the electric motor 5.
- the drive wheel 8 is of general appearance cylindrical, with a central portion 19 in the form of a toric cross section substantially semi-circular, and two end portions 20, 20 ', having each a cylindrical periphery interrupted at regular intervals by flats 21, with the particularity that the flats 21 of the portion 20 face cylindrical zones 22 'of the portion 20', while conversely the flats 21 'of the portion 20 'face cylindrical zones 22 of the portion 20.
- the support wheel 11 with which the drive wheel 8 cooperates takes the form of a generally cylindrical appearance but comprising in its middle portion a toric bead 23, the relief section of which corresponds substantially in the hollow section of the gutter of the wheel 8.
- the compression wheel 14 has the appearance general cylindrical and has two portions of crenellated ends 24, 24 ' joined by a neutral middle portion 25; moreover, the support wheel 17 is a smooth cylinder on which the grooves 24, 24 'will roll.
- the M-band material, coming from the first pair of wheels 8/11, is clamped between said grooves 24, 24 ' and this smooth surface, with varying force.
- This compression is however limited and cannot damage said material, since it is not deformed between gear teeth meshing with each other as in previous systems.
- the action of the grooves 24, 24 'on the material is therefore ensure by this simple compression, the assembly of the sheets of said material and the cohesion of this assembly, by crushing the folds of the paper.
- crumpling function is fulfilled by a purely phenomenon mechanical not affecting the solidity of the material.
- the incremental encoder c is housed at the end of the shaft 15 (see Figures 1 and 4), opposite the toothed wheel 16c, and therefore the motor 5. It is fixed in a bore made in the end of said shaft 15, in which a outer shaft of said encoder c, in a manner known per se, using a screw fixing of the inner ring of the bearing located at this end, which is applied against the outer shaft of the encoder c like a needle. This screw passes through therefore radially all the non-bored part of the shaft 15, and must be provided more elongated than if it were only intended to fix said inner ring on tree 15.
- the encoder c is connected goes a cable e to the electronic card forming the unit central unit, to which it sends the pulses necessary for counting, and of which it receives the operating voltage.
- the advance motor is stopped automatically, which is shown schematically by the s switch placed for needs of the explanation at the output of the comparator.
- the operation exact is the one already mentioned, namely centralized management by a microprocessor and an EPROM, which perform the comparison and manage the motor in advance. It is therefore in reality a programmed operation, and not based on discrete components, used to clarify the explanation, and which could be the subject of a variant of the device of the invention.
- Figure 5 shows a detail of an example of an external housing allowing the operator to communicate with the machine, and for this purpose comprising a keyboard k, a display a, and an LED r whose state reflects the power-up of the assembly.
- this keyboard has literal keys (S, E) which are used to select the possible operating modes, using the S key, and their validation by the E key.
- S, E literal keys
- the different modes scroll sequentially. and allow, using messages appearing on the display a, to enter on the keyboard k the information necessary for the central processing unit to operate the machine.
- the accuracy of the measurement can also be adapted to the conditions or the quality of the paper. Indeed, depending on the resolution of the encoder incremental chosen, you can calibrate the number of pulses corresponding to a unit of measurement, whether this is cm or inch in Anglo-Saxon countries.
- Going from 30 to 31 is a difference of approximately 1 mm.
- Figure 6 is a simplified block diagram of said operation.
- This figure illustrates more particularly the methodology used by the EPROM resident program, without entering into the details relating to the addresses for storing the values, nor communicate the detailed programs, which are within the competence of those skilled in the art.
- a signal is sent by the central unit uc at the address of the advance motor, to make it stop.
- Figure 7 shows the attachment of an inductive proximity sensor 40 on the cover 41 of a motor, controlling the advance of the padded strip M.
- the detector 40 is located on the periphery of the cover, so as to be close to at least one element 38 fixed between the blades 42 of the fan 43 generally placed at the end shaft for an electric motor.
- said element 38 may be a screw fixed in a thread on the flange 39 of the fan 43.
- the relative positioning of element 38 / detector is particularly clearly seen, as well as the possibility of distance adjustment allowing optimal operation of detector 40.
- the cover 41 has an opening 34 opening access to an internal nut 35, allowing in combination with an external nut 36 simultaneously the tightening of the sensor 40 and its position adjustment relative to the elements 38 of the fan 43.
- the distance d must obviously be able to be adjusted with fairly great precision, so as to allow correct operation of the proximity detector 40.
- This one has a sensitivity such that it allows him, if he is correctly positioned, to detect the passage of these blades 42 of the fan 43 when they pass to proximity to its inner end; however, with detection devices chosen, this is only true if said blades 42 include metal detectable by the 40 sensor.
- the fans are usually aluminum, but it turned out that the most common detectors work best if at least one element additional metal 38 is fixed to the fan 43.
- the detector For the measurement of the length of padded strip produced, the detector is placed on the feed motor referenced 5 in FIG. 1. The signal is directly sent to the central unit uc, which counts the pulses sent by the detector 40, and processes them to measure said length, as a function of stored data, such as the number of pulses corresponding to a unit of length for the quality of paper used and length to produce.
- the simplified block diagram of operation is the same as in operation with the incremental encoder.
