Description

Dough sheet thickness measuring device and calendaring equipment

Technical Field

The utility model relates to the technical field of dough sheet processing, in particular to a dough sheet thickness measuring device and calendaring equipment comprising the dough sheet thickness measuring device.

Background

In the production process of the noodle product, flour and water are mixed according to a specific proportion, and then rolled into the noodle. The dough sheet is rolled for a plurality of times to reach the target thickness, enters a shredding cutter, is cut into noodle threads with specific width, and is made into instant noodles or fine dried noodles through subsequent treatment.

In the traditional process, when the dough sheet is rolled, an operator of equipment is required to measure the thickness of the dough sheet by using a thickness meter, and if the measurement result deviates from the target thickness, the rolling distance between two sides of the pressing roller is required to be respectively adjusted, so that the thickness of the dough sheet is changed.

However, this conventional approach has several problems:

1. the potential safety hazard of food can increase the possibility of the dough sheet being polluted in the manual measurement process.

2. The thickness measurement depends on the level of an operator and the instrument precision, and the thickness measurement instrument for the dough sheet at present is low in precision, namely about + -0.02 mm. Taking 1mm thick instant noodle as an example, the waste of energy and raw materials is about 4%. In addition, greater errors and wastage can be introduced due to operator artifacts.

3. The thickness cannot be monitored in real time, and when the machine vibrates or a person operates by mistake, the thickness of the dough sheet can change. If not found in time, waste and even reject products are generated.

It should be understood, however, that the detailed description and the specific examples, while indicating specific ways of making and using the utility model, are intended for purposes of illustration only and are not intended to limit the scope of the utility model. The terms "comprising" or "including" are used herein in their broadest sense to mean and encompass the concepts of "including," comprising, "" consisting essentially of, "and" consisting of. The use of "e.g.", "such as" and "including" to list illustrative examples is not limited to the examples listed. Thus, "for example" or "such as" means "for example but not limited to" or "such as but not limited to" and encompasses other similar or equivalent examples.

Referring to fig. 1 and 2, an exemplary calendaring apparatus 100 is shown, according to an embodiment of the utility model, for calendaring a dough sheet, for example. The calendaring apparatus 100 includes a first or upper calendaring roller 110a and a second or lower calendaring roller 110b, a dough-sheet thickness measuring mechanism or device 101, and a roll gap adjusting mechanism or device. The dough sheet thickness measuring device 101 is used for measuring the thickness of the dough sheet 111 rolled by the first rolling roller 110a and the second rolling roller 110b, and a roll gap adjusting mechanism or device is coupled to at least one of the first rolling roller 110a and the second rolling roller 110b for adjusting the roll gap between the first rolling roller 110a and the second rolling roller 110 b. The calendaring apparatus 100 may further include: control circuitry 103 coupled to an output of the patch thickness device 101 to obtain measurement data; a human-computer interaction device 104 for presenting the actual thickness of the dough sheet 111 measured via the dough sheet thickness measuring apparatus 101.

It should be appreciated that the roll gap adjustment mechanism or device of the calendaring apparatus 100 may be the roll gap adjustment mechanism 102 according to embodiments of the present disclosure, or any known or future developed roll gap adjustment mechanism in the art (e.g., manual or electrically controlled) may be employed such that when a measured thickness of a dough sheet is found to be inconsistent with a target thickness, the roll gap adjustment mechanism may be utilized to adjust the distance between the calendaring rollers to adjust the thickness of the calendared dough sheet.

As shown in fig. 2, the dough sheet thickness measuring device 101 includes one or more sets of thickness measuring sensors (1011, 1012) disposed at upper and lower positions of the dough sheet 111 between the first calender roll 110a and the second calender roll 110 b. Each set of thickness sensors (1011, 1012) includes a first thickness sensor (0001 a, 1012) and a second thickness sensor (1012 b, 1012) disposed asymmetrically with respect to the sheet 111, with the sheet 111 between the first thickness sensor (1011 a,1012 a) and the second thickness sensor (1012 b ). For example, a first thickness measurement sensor (0001 a,1012 a) is disposed above the upper surface 112a of the face sheet 111, and a second thickness measurement sensor (1012 b ) is disposed below the lower surface 112b of the face sheet 111.

As shown in fig. 3, ideally, the rolled dough sheet 111 will be in the direction of the reference surface 114 (i.e., the reference surface indicates the desired or predetermined dough sheet positioning direction), for example, due to mechanical vibration, the dough sheet 111 may oscillate relative to the reference surface 114, thereby creating a relatively fixed offset angle θ. For example, the swing angle θ may be measured in advance (for example, by a measuring instrument or by an angle sensor (not shown) disposed at the rolling apparatus). The outputs of each set of thickness measurement sensors (1011, 1012) are coupled to the control circuit 103, and the control circuit 103 is coupled to the human-machine interaction device 104.

Furthermore, fig. 3 shows a set of asymmetrically arranged thickness sensors (1011 a,1011 b) arranged in up and down positions of the patch, which may introduce installation measurement errors due to the fact that the manufacturing and installation may not be able to make the sensor rays absolutely perpendicular to the patch 111. For example, the first gauge sensor 1011a is actually disposed at a first angle (e.g., 90 ° - α) that is non-perpendicular relative to the reference plane 114, and the second gauge sensor 1011b is actually disposed at a second angle (e.g., 90 ° - β) that is non-perpendicular relative to the reference plane 114. For example, the first angle and the second angle may be the same or different. The first and second angles may be considered to be relatively fixed during calendering of the dough sheet in actual production, for example, the angles α, β or the first and second angles may be measured in advance (e.g., by a measuring instrument or by an angle sensor arranged at the calendering apparatus). For example, an angle sensor may be included in the patch thickness device, and an output of the angle sensor is coupled to an input of the control circuit 103. Alternatively, the various angles obtained by the measuring instrument may be directly transferred to an input of the control circuit 103 (e.g., via an input interface circuit, as known to those skilled in the art).

Both the first and second angles and the possible oscillation angle θ of the sheet 111 with respect to the reference surface 114 may cause errors in measurement, and in fact the oscillation is difficult to avoid and the errors caused thereby may be large.

For example, if a set of sensors (0001 a, 521 b) is symmetrically arranged, the patch thickness t may be calculated according to the following formula (1):

L＝t+L ₁ +L ₂ (1)

where L is the distance between the two sensors, L ₁ Is the distance L from the sensor 1011b to the lower surface 112b of the patch 111 ₂ Is the distance of the sensor 1011a from the upper surface 112a of the patch 111.

However, since the sensor mounting is not perfectly perpendicular to the patch, while the patch is slightly oscillated, even a change in thickness may cause a secondary measurement error, these angles α, β, and θ must be considered in calculating the thickness of the patch to reduce the measurement error caused thereby.

In the case where a group of sensors (1011 a,1011 b) is asymmetrically arranged as shown in fig. 3, the sheet thickness t can be calculated according to the following formula (2):

L＝t+L ₁ +L ₂ +ΔL (2)

wherein, by introducing correction coefficient Δl to compensate for error reduction, Δl can be calculated according to the following formula (3):

for example, when θ is not 0, Δl is a correction coefficient other than 0.

Assume an initial value compensation coefficient L ₀ ＝t+L ₁₀ +L ₂₀ +Δl, then the patch thickness t=l ₀ -(L ₁₀ +L ₂₀ +ΔL)。

Therefore, the asymmetrically arranged sensor may be more accurately used to determine the dough sheet thickness than the symmetrically arranged sensor to reduce or avoid measurement errors due to manufacturing and mounting of the sensor and the dough sheet runout, thereby obtaining more accurate thickness measurements for timely adjusting the dough sheet thickness, thereby avoiding waste of manpower, energy and raw materials during calendaring. In addition, the sensor arrangement eliminates the food safety hazard of the dough sheet being polluted in the manual measurement process, and has higher precision than the measurement by an operator through an instrument. For example, the measurement accuracy of the sensor may be up to 1um, while the accuracy of the patch meter is typically about ±0.02mm.

For example, since the parameters of the above formulas (1) and (2) are given by measurement in advance, the calculation of the sheet thickness can be realized by a calculation circuit set in advance. For example, the computing circuitry may be implemented by any of a Micro Control Unit (MCU), digital logic control circuitry, programmable calculator (e.g., portable calculator), programmable controller (PLC), programmable logic array (FPGA), or pure hardware circuitry to perform similar functions, as is well known to those skilled in the art. For example, a programmable calculator or controller known in the art may incorporate scientific calculations, and the patch thickness t may be calculated by inputting measurement data obtained by the patch thickness measuring device 101 as variables into a predetermined function. For example, the computing circuit may be part of the control circuit 103, and the control circuit 103 may provide the calculated thickness t to the human-machine interaction device 104 in order to present the actual thickness t of the dough sheet measured via the thickness measuring sensor on the human-machine interaction device 104. For example, the human-machine interaction device 104 may include a display device, such as various displays known in the art.

As shown in fig. 2, the asymmetrically arranged first and second thickness measuring sensors 2, 3 may be fixed to a bracket 1, the bracket 1 being used to adjust the positions of the first and second thickness measuring sensors 2, 3. For example, the first and second thickness measuring sensors 2, 3 may each be a laser displacement sensor, and the support 1 may adjust the position at which the sensors illuminate, such as any one or more of the distance between the sensors, the distance of the sensors relative to the patch, and the angle of the sensors relative to the reference plane. For example, once the position of the sensor illumination is adjusted via the bracket 1, the distance between the sensors and the angle of the sensors relative to the reference plane can be initially obtained.

As shown in fig. 2, the thickness measuring sensor includes 2 sets of thickness measuring sensors (1011, 1012) horizontally spaced apart between the left and right ends of the face sheet 111, respectively disposed at the left and right ends of the face sheet 111, and accuracy of measurement results can be further improved by repeated measurement of the plurality of sets of sensors. It should be understood that more or fewer sensors (e.g., 1 set, 3 sets, or more) may also be disposed between the left and right ends of the dough sheet.

The roll gap adjustment mechanism 102 may be coupled to a roll bearing housing corresponding to at least one of the upper and lower roll 110a, 110b for adjusting the roll gap between the upper and lower roll 110a, 110 b. Each calender roll bearing housing is for receiving a respective calender roll. As shown in fig. 1, 2 and 4, the nip adjusting mechanism 102 is coupled to the calender roll bearing housing 9 of the upper calender roll 110a to drive the movement (e.g., up-down movement) of the upper calender roll 110 a. In other examples, the stand off adjustment mechanism 102 may drive movement of the lower calender roll or movement of both the upper and lower calender rolls.

For example, the roll gap adjustment mechanism 102 includes a lifter coupled to the calender roll bearing housing corresponding to the at least one calender roll and a motor coupled to the lifter for driving the lifter for lifting the calender roll bearing housing.

As shown in fig. 4, the lifter of the roll gap adjustment mechanism 102 includes an adjustment screw or rod 7 and a reduction gearbox (or speed reducer) 6. The reduction gearbox 6 is coupled to the adjusting screw or screw 7 and directly coupled to the motor 5, wherein one end of the adjusting screw or screw 7 is coupled to a calender roll bearing housing corresponding to at least one calender roll, for example, calender roll bearing housing 9 corresponding to an upper calender roll of fig. 4, the motor 5 is used to drive the reduction gearbox 6, and the reduction gearbox 6 is used to drive the movement of the adjusting screw or screw 7 such that the movement (e.g., up-down movement) of the adjusting screw or screw 7 drives the movement (e.g., up-down movement) of the upper calender roll, thereby adjusting the thickness of the dough sheet. In other examples, the adjusting screw of the roll gap adjusting mechanism may also be coupled to the calender roll bearing housing 11 corresponding to the lower calender roll to drive the movement (e.g., up-down movement) of the lower calender roll.

In the embodiment of fig. 4, one end of the adjusting screw or threaded rod 7 may be connected to a rotation stopping member 8, and the rotation stopping member 8 may be connected to a calender roll bearing block 9 by a fastener. The rotation stopping means 8 can prevent the adjusting screw or the screw rod 7 from rotating during the up-and-down movement.

In the embodiment of fig. 4, the roll gap adjustment mechanism 102 further comprises a torque arm assembly 12 and a worm gear support 13, wherein the motor 5 is connected to the torque arm assembly 12 and the worm gear support 13 is connected to the torque arm assembly 12 and the reduction gearbox 6. In this way, the motor 5 is also indirectly connected to the reduction gearbox 6 through the torque arm assembly 12 and the worm gear bracket 13, so that the motor 5 can be limited to be thrown in the process of driving the adjusting screw rod or the screw rod 7 by the reduction gearbox 6, and meanwhile, the torque arm assembly 12 and the worm gear bracket 13 can play a role in assisting in transmitting driving force.

Optionally, the motor 5 is a gear motor, and an output hole of the gear motor 5 is connected to a shaft extension of the reduction gearbox and is used for driving the adjusting screw rod or the screw rod 7 to move up and down. For example, the motor 5 is an asynchronous motor integrated with a worm gear reducer, and inertia during transmission can be reduced by connecting the output hole of the worm gear reducer of the motor 5 with the reducer 6.

Alternatively, the other end of the adjusting screw or screw 7 engages the reduction gearbox 6 by means of a screw thread.

For example, the adjusting screw or screw 7 is a self-locking screw or screw so as to lock when the adjusting screw or screw 7 is moved to a desired position or a given position, thereby maintaining the lock of the roll distance. For example, when the ratio of the pitch and circumference of the adjusting screw or screw 7 is smaller than a specific value, the adjusting screw or screw 7 is a self-locking screw or screw. For example, the trapezoidal screw 7 is screwed with the internal thread of the reduction gearbox 6, and the trapezoidal screw 7 satisfies the self-locking condition.

For example, the reduction gearbox 6 may be a worm gear reduction gearbox.

Turning back to fig. 1, optionally, the motor 5 of the roll gap adjustment mechanism 102 may be coupled to the control circuit 103 to enable adjustment (e.g., automatic adjustment) of the roll gap by the roll gap adjustment mechanism 102 via electrical control to avoid the following problems with manual adjustment: the adjustment time is long, and the manpower resource is wasted; the adjustment precision is poor, and in the adjustment process, the thickness of the produced dough sheet is often unqualified, and the waste of energy and raw materials can be caused.

Alternatively, the motor 5 may be coupled to a motor drive unit (not shown) coupled to the control circuit 103 for controlling the steering of the motor 5. For example, the steering of the motor 5 can be used to determine the direction of movement of the adjusting screw or threaded rod 7. For example, the motor drive unit may be various motor drive units known in the art, such as a frequency converter or the like. In some examples, the motor drive unit may be integrated with the motor 5 or with the control circuit 103. In some examples, an output (e.g., an output control) of the control circuit 103 may be directly connected to the motor 5, outputting a pulse signal (e.g., a pulse signal of a particular frequency (e.g., 50Hz, etc.) to the motor 5 for controlling the steering of the motor 5.

Alternatively, the setting of the facesheet thickness may be received via the human-machine interaction device 104. For example, the human-machine interaction device 104 may be provided with one or more input devices, such as buttons, a touch screen, a microphone to receive user input to set a patch thickness, e.g., a target thickness of the patch or a thickness error threshold. For example, when the difference between the actual thickness of the dough sheet and the target thickness is less than the thickness error threshold, it may not be necessary to adjust the nip between the calender rolls by the nip adjustment mechanism.

Alternatively, the first calender roll bearing housing 7 corresponding to the upper calender roll 110a and the second calender roll bearing housing 9 corresponding to the lower calender roll 110b may be connected by a spring (e.g., the spring 10 of fig. 4) to avoid collision of the upper calender roll and the lower calender roll during the nip adjustment, thereby preventing damage of the calender rolls. In addition, in addition to the limiting effect, the supporting force provided by the spring 4 to the calender roll bearing block can be beneficial to more accurately realizing the screw connection in the process of adjusting the screw rod or the screw rod 7 to move up and down.

As shown in fig. 5, the nip adjusting mechanism 102 includes a first nip adjusting mechanism 102a and a second nip adjusting mechanism 102b coupled to the left and right ends of the first reduction roller 110a, respectively, so as to uniformly achieve adjustment of the nip between the first reduction roller 110a and the second reduction roller 110 b.

Fig. 6 shows an exemplary logic circuit implementing the control circuit 103 and its connections.

As shown in fig. 6, the control circuit 103 includes a first interface module 1031 (e.g., an input interface) to obtain measurement data from the patch thickness measurement device 101, such as measurement distances (e.g., L1, L2 as described above with respect to fig. 3) from the thickness measurement sensors (521 a, 521 b), and optionally measurement angles (e.g., θ, α, β or first, second angles as described above with respect to fig. 3) from the angle sensors or measured angles (e.g., θ, α, β or first, second angles as described above with respect to fig. 3) from the measurement instrument.

As shown in fig. 6, the control circuit 103 further includes a calculation circuit 1032 for calculating the patch thickness t (e.g., as described above with respect to fig. 3) from the measurement data obtained from the first interface module 1031.

As shown in fig. 6, the control circuit 103 further comprises a second interface module 1034 (e.g., an input/output interface), the second interface module 1034 being connected to the human-machine interaction device 104 for providing the calculated patch thickness t to the human-machine interaction device 104 for presenting the actual patch thickness t by the human-machine interaction device 104. The human-machine interaction device 104 may also receive user input for roll adjustment and provide the user input to the control circuit 103 via the second interface module 1034. For example, the human-machine interaction device 104 may also present a target thickness of the dough sheet such that a user initiates a request for a roll gap adjustment via the human-machine interaction device 104 upon finding that the actual thickness of the dough sheet does not meet the target thickness, e.g., via sending an edge-triggered pulse signal to the second interface module 1034, such that the control circuit 103 may determine that a roll gap adjustment is required by detecting the pulse signal (e.g., using various trigger circuits known in the art).

The human-machine interaction device 104 may also provide the target thickness of the dough sheet to the control circuit 103 via the second interface module 1034. Also, the control circuit 103 may include a comparison circuit 1036 for comparing the calculated patch thickness t with the target thickness, the comparison circuit 1036 may be implemented using various comparators known in the art, and the comparison circuit 1036 outputs a comparison result to indicate whether the patch thickness t is greater than or less than the target thickness.

The control circuit 103 may further comprise a third interface module 1033 (e.g., an output interface), the third interface module 1033 being connected to the roll gap adjustment mechanism 102, more specifically, the motor 5 of the roll gap adjustment mechanism 102, so as to drive the reduction gearbox 6, and thereby the adjusting screw or the screw 7, by controlling the rotation of the motor 5, to drive the calender rolls to move with the calender roll bearing block. For example, the control circuit 103 may determine the signal transmitted to the motor 5 through the third interface module 1033 according to the comparison result of the dough sheet thickness t and the target thickness, so as to implement automatic measurement of the dough sheet thickness and automatic adjustment of the rolling distance, without manual intervention, thereby saving manpower. Alternatively, the control circuit 103 may determine the signal transmitted to the motor 5 through the third interface module 1033 according to a request for roll gap adjustment from the human-machine interaction device 104. For example, the transmitted signals may be generated based on a predetermined signal generating circuit such that when an increase in roll distance is required, a first pulse signal is transmitted, and when a decrease in roll distance is required, a second pulse signal is transmitted, for example, the output of the different pulse signals may be achieved by connecting a multiplexer to one or more signal generating circuits.

The control circuit 103 may further include a fourth interface module 1035 (e.g., an output interface), where the fourth interface module 1035 is connected to the alarm circuit 105, and the control circuit 103 is configured to control the alarm circuit 105 to send an alarm according to the comparison result of the comparison circuit 1036, and prompt the user to prompt whether the patch thickness meets the requirement of the target thickness. For example, the control circuit 103 may transmit a first alarm control signal to the alarm circuit 105 in response to the patch thickness t being greater than the target thickness, and transmit a second alarm control signal to the alarm circuit 105 in response to the patch thickness t being less than the target thickness, the alarm circuit 105 issuing a different alarm in response to receiving a different alarm control signal. For example, the alarm circuit 105 may include a display alarm circuit (e.g., a light emitting diode, etc.) and/or an audible alarm circuit (e.g., a buzzer, etc.), as known in the art.
