Description

Technical Field

[0001] The present invention relates to the field of product diversion technology, and in particular to a phase determination method and apparatus, equipment, and storage medium. Background Art

[0002] Currently, with advances in manufacturing technology, the speed at which production equipment can produce products has greatly increased. However, the packaging machines at the back end are limited by some processes, such as the heat sealing process or other processes, and the packaging speed cannot keep up with the production speed. Therefore, multiple packaging machines are needed to adapt to the production equipment. When there are multiple packaging machines at the back end, the products produced by the production equipment need to be automatically separated into pieces, which requires a sheet sorter. For example, the current production equipment can produce sanitary napkins at a speed of 1,200 pieces per minute, but the packaging machines at the back end can only package a maximum of 700 pieces per minute, so two or three packaging machines are needed to adapt to the production equipment. The sheet sorter first sorts 10 sanitary napkins into packaging machine No. 1, then sorts 10 sanitary napkins into packaging machine No. 2, and so on.

[0003] The process preceding the sheet sorter is product production equipment, which needs to cut continuous strips of material into equal segments. This process is typically accomplished using a wheel cutter. This wheel cutter consists of a drum with one or more cutters positioned around its circumference. As the material is transported beneath the drum, the cutters continuously cut it into the required lengths as the drum rotates.

[0004] From the perspective of the workflow, as long as the speed of the product production equipment is constant, the position of the corresponding wheel cutting device is also constant when each product is cut, that is, the phase of the product is fixed. After the product is cut, it is transported to the entrance of the sheet unscrambler via a conveyor belt. Due to the relative sliding between the product and the conveyor belt during transportation, the phase of the product is offset after entering the sheet unscrambler. However, the subsequent process actions of the sheet unscrambler require the phase of the product to be fixed. The first process section of the sheet unscrambler is the equal-pitch processing equipment, which is used to arrange and output each product at equal intervals. When the phase of the product is offset, the product will not be able to enter the equal-pitch processing equipment, causing the product to be thrown out, and in severe cases, the conveyor belt will be stuck.

[0045] DETAILED DESCRIPTION

[0046] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0047] In the first aspect, an embodiment of the present invention provides a phase determination method, which is used to adjust the phase of products output by product production equipment so that the products output by the product production equipment can smoothly enter the equally spaced processing equipment, avoiding the products being thrown out due to inability to enter the equally spaced processing equipment and avoiding problems such as conveyor belt jamming.

[0048] Equal spacing processing equipment can be found in Figure 1 ,from Figure 1As can be seen in the figure, the evenly spaced processing equipment 200 includes a conveyor belt 210 and baffles 220 evenly distributed on the conveyor belt. The spacing between each two adjacent baffles 220 is equal. When a product 300 enters the evenly spaced processing equipment, it is blocked by a spring, causing the product 300 to stop. When a baffle 220 on the conveyor belt 210 moves to the spring, it pushes the product 300 away. Because the baffles 220 on the evenly spaced processing equipment are evenly distributed, the spacing between each product 300 after passing through the evenly spaced processing equipment is the same, thus achieving evenly spaced output of the products 300.

[0049] When the phase of the equally spaced processing device 200 is appropriate, the product 300 can enter the equally spaced processing device between the two blocking rods 220. However, when the phase of the equally spaced processing device is not appropriate, the product 300 will collide with the blocking rod 220 when entering the equally spaced processing device, resulting in the product 300 being unable to enter the equally spaced processing device.

[0050] In order to ensure that the products can enter the equally spaced processing equipment, phase adjustment is required. However, since the phase of the products entering the equally spaced processing equipment is mainly determined by the product production equipment, the phase of the product production equipment cannot be adjusted. Therefore, in the embodiment of the present invention, the phase of the equally spaced equipment is adjusted.

[0051] See also Figure 2 The method provided by the embodiment of the present invention includes the following steps S110 to S140:

[0052] S110, obtaining a reference phase value of an equidistant processing device; wherein the equidistant processing device is used to output products produced by the product production device according to a preset equidistant interval;

[0053] In actual scenarios, a person can input a reference phase value in the human-computer interaction interface of a computing device and use it as the reference value for each phase adjustment.

[0054] S120, determining a first phase difference corresponding to when the product production equipment is running at a uniform speed; wherein the first phase difference is the difference between a phase value of the product production equipment and a phase value of the equally spaced processing equipment when the product production equipment is running at a uniform speed;

[0055] It is understandable that when the product production equipment is running at a uniform speed and the equally spaced processing equipment is also running at a uniform speed, the phase difference between the product production equipment and the equally spaced processing equipment is a constant. As long as the phase difference between the two can ensure that the product can smoothly enter the equally spaced processing equipment when the product production equipment is running at a uniform speed, the phase difference can be used as the first phase difference.

[0056] Among them, the first phase difference is the phase difference between the product production equipment and the equally spaced processing equipment when the product production equipment is running at a uniform speed. This phase difference is used as a reference. Even if the product production equipment is in a non-uniform speed state, for example, acceleration or deceleration, as long as the phase difference between the product production equipment and the equally spaced processing equipment is still the first phase difference, it can be ensured that the product can smoothly enter the equally spaced processing equipment.

[0057] In a specific implementation, two sensors can be set: a first sensor and a second sensor, and two encoders can be set at the same time: a first encoder and a second encoder. The first sensor is set at the product production equipment, and as long as the wheel cutting device of the product production equipment rotates one circle, the first sensor sends an induction signal. The second sensor is set at the equidistant processing equipment, and as long as the barrier rod of the equidistant processing equipment rotates one circle, the second sensor sends an induction signal. According to the time interval between the induction signals received from the first sensor, it can be known whether the product production equipment is running at a uniform speed. Similarly, according to the time interval of the induction signals sent by the second sensor, it can be known whether the equidistant processing equipment has also entered a uniform speed state. When both enter a uniform speed state, the encoder position can be obtained from the first encoder, and then the phase of the product production equipment can be known. At the same time, the encoder position can be obtained from the second encoder, and then the phase of the equidistant processing equipment can be known. The two phase values ​​are subtracted to obtain the above-mentioned first phase value.

[0058] For example, in a uniform speed state, the phase of the product production equipment is S rk1 , the phase of the equally spaced processing equipment is S es1 , the first phase difference is: ΔS1=S rk1 -S es1 .

[0059] S130, obtaining a real-time phase difference between the product production equipment and the equally spaced processing equipment;

[0060] It is understandable that the phase can be adjusted according to the method provided in the embodiment of the present invention at any time, especially when the product production equipment is in a non-uniform speed state. Of course, this solution is also applicable when the product production equipment is in a uniform speed state, in which case the real-time phase difference and the above-mentioned first phase value are equal. However, if the product production equipment is in a non-uniform speed state, the real-time phase difference and the above-mentioned first phase value are not equal, and it is even more necessary to use the method provided in the embodiment of the present invention to perform phase adjustment.

[0061] In specific implementation, the position of the first encoder and the position of the second encoder can be obtained at the same time, so as to know the phase of the product production equipment and the phase of the equidistant processing equipment at the same time, and the real-time phase difference is obtained by subtracting the two phase values.

[0062] For example, at any moment, the phase of the product production equipment is S rkt , the phase of the equally spaced processing equipment is S est , the real-time phase difference is: ΔS t =S rkt -S est .

[0063] S140: Determine a target phase value of the equidistant processing device according to the reference phase value, the first phase difference, and the real-time phase difference.

[0064] It can be understood that based on the user-set baseline phase value, the first phase difference at a constant speed, and the real-time phase difference at any moment, the target phase value of the equally spaced processing equipment at any moment can be calculated. By adjusting the phase value of the equally spaced processing equipment to the target phase value, the phase difference between the product production equipment and the equally spaced processing equipment can be maintained at the first phase difference, allowing the product to enter the equally spaced processing equipment smoothly.

[0065] In the specific implementation, see Figure 3 , S140 may specifically include the following steps S141 to S142:

[0066] S141. Determine a phase compensation value of the equidistant processing device according to the first phase difference and the real-time phase difference;

[0067] It is understandable that in order to keep the phase difference between the product production equipment and the equally spaced processing equipment constant at any time, ΔS is required t =ΔS1. Since the phase of the production equipment cannot be adjusted, only the phase of the equally spaced processing equipment can be adjusted. Therefore, the equation is: S rkt -(S est +X t )=S rk1 -S es1 Based on this equation, we can get X t =S rkt -S est -(S rk1 -S es1 ), that is, the first calculation formula: X t =ΔS t -ΔS1.

[0068] In a specific implementation, in S141, a first calculation formula may be used to calculate the phase compensation value, where the first calculation formula is:

[0069] X t =ΔS t -ΔS1

[0070] Where, X tis the phase compensation value at time t, ΔS1 is the first phase difference, ΔS t is the real-time phase difference at time t.

[0071] S142: Determine a target phase value of the equidistant processing device according to the reference phase value and the phase compensation value.

[0072] It is understandable that after the phase compensation value is calculated, the target phase value can be calculated based on the reference phase value and the phase compensation value. In specific implementation, the target phase value can be calculated using a second calculation formula in S142, and the second calculation formula includes:

[0073] P t =P rv +X t

[0074] Where, P t is the target phase value at time t, P rv is the reference phase value, X t is the phase compensation value at time t.

[0075] That is, the reference phase value and the phase compensation value are summed to obtain the target phase value. t =P rv +S rkt -S est -S rk1 +S es1 .

[0076] In a specific implementation, in order to avoid a large correction amount at a time, which would cause the equal-interval processing equipment to accelerate or decelerate suddenly, an upper limit value can be set for the phase compensation value. Through multiple small corrections, the equal-interval processing equipment can adjust the phase value smoothly. Therefore, before step S142, the method may further include:

[0077] Determining whether the phase compensation value is greater than a preset compensation upper limit;

[0078] If so, determining a target phase value of the equidistant processing device according to the reference phase value and the preset compensation upper limit;

[0079] Otherwise, execute the step of "determining the target phase value of the equidistant processing device according to the reference phase value and the phase compensation value".

[0080] That is, after executing S141 and before executing S142, it can be determined whether the phase compensation value is greater than the preset compensation upper limit. If it is less than or equal to the preset compensation upper limit, S142 is executed and the target phase value is calculated according to the original method. However, if the phase compensation value is greater than the preset compensation upper limit, the current correction is to determine the target phase value of the equally spaced processing device based on the reference phase value and the preset compensation upper limit, and then the phase of the equally spaced processing device can be adjusted and controlled based on the target phase value.

[0081] Furthermore, when the phase compensation value is greater than a preset compensation upper limit, a specific method of determining the target phase value of the equidistant processing device based on the reference phase value and the preset compensation upper limit may be: calculating the target phase value using a third calculation formula, wherein the third calculation formula includes:

[0082] P t =P rv +X h

[0083] Where, P t is the target phase value at time t, P rv is the reference phase value, X h is the preset compensation upper limit.

[0084] That is to say, in this correction, only the preset compensation upper limit and the reference phase value are summed to obtain the target phase value. Of course, the next correction is still needed. Through multiple corrections, the phase difference between the product production equipment and the equidistant processing equipment is kept constant.

[0085] The phase determination method provided by an embodiment of the present invention first obtains a reference phase value of an equidistant processing device, then determines a first phase difference between the product production equipment and the equidistant processing equipment when the product production equipment rotates at a uniform speed, and then determines the real-time phase difference between the two, and then determines the target phase value of the equidistant processing equipment based on the reference phase value, the first phase difference, and the real-time phase difference, and then uses the target phase value to adjust the equidistant processing equipment, so that the phase difference between the product production equipment and the equidistant processing equipment always maintains a dynamic balance at any time, so that the product can smoothly enter the equidistant processing equipment, avoiding being thrown out due to inability to enter the equidistant processing equipment and avoiding problems such as conveyor belt jamming.

[0086] In a second aspect, an embodiment of the present invention provides a phase determination device.

[0087] See also Figure 4 , the phase determination device 100 includes:

[0088] A first acquisition module 110 is configured to acquire a reference phase value of an equidistant processing device, wherein the equidistant processing device is configured to output products produced by a product production device according to a preset equidistant interval;

[0089] A first determining module 120 is configured to determine a first phase difference corresponding to when the product production equipment is operating at a uniform speed; wherein the first phase difference is the difference between a phase value of the product production equipment and a phase value of the equally spaced processing equipment when the product production equipment is operating at a uniform speed;

[0090] A second acquisition module 130 is used to obtain a real-time phase difference between the product production equipment and the equally spaced processing equipment;

[0091] The second determining module 140 is configured to determine a target phase value of the equidistant processing device according to the reference phase value, the first phase difference, and the real-time phase difference.

[0092] In one embodiment, the second determining module includes:

[0093] a compensation determining unit, configured to determine a phase compensation value of the equidistant processing device according to the first phase difference and the real-time phase difference;

[0094] The first determining unit is configured to determine a target phase value of the equidistant processing device according to the reference phase value and the phase compensation value.

[0095] Furthermore, the second determining unit further includes:

[0096] A judging unit, configured to judge whether the phase compensation value is greater than a preset compensation upper limit before the first determining unit determines the target phase value of the equidistant processing device;

[0097] a second determining unit, configured to determine a target phase value of the equidistant processing device according to the reference phase value and the preset compensation upper limit when the phase compensation value is greater than a preset compensation upper limit;

[0098] Correspondingly, the first determining unit is configured to determine the target phase value of the equidistant processing device according to the reference phase value and the phase compensation value when the phase compensation value is less than or equal to a preset compensation upper limit.

[0099] In one embodiment, the compensation determination unit is configured to calculate the phase compensation value using a first calculation formula, where the first calculation formula is:

[0100] X t =ΔS t -ΔS1

[0101] Where, X tis the phase compensation value at time t, ΔS1 is the first phase difference, ΔS t is the real-time phase difference at time t.

[0102] In one embodiment, the first determining unit is configured to calculate the target phase value using a second calculation formula, where the second calculation formula includes:

[0103] P t =P rv +X t

[0104] Where, P t is the target phase value at time t, P rv is the reference phase value, X t is the phase compensation value at time t.

[0105] In one embodiment, the second determining unit is configured to calculate the target phase value using a third calculation formula, where the third calculation formula includes:

[0106] P t =P rv +X h

[0107] Where, P t is the target phase value at time t, P rv is the reference phase value, X h is the preset compensation upper limit.

[0108] It is understandable that the explanation, specific implementation, beneficial effects, examples, etc. of the relevant contents in the device provided by the embodiment of the present invention can be found in the corresponding parts of the method provided in the first aspect, and will not be repeated here.

[0109] Thirdly, see Figure 1 An embodiment of the present invention provides an equidistant processing device 200, comprising a conveyor belt 210, at least two baffles 220 evenly distributed on the conveyor belt 210, a drive motor and a controller; wherein the drive motor is used to drive the conveyor belt 210 to move, so that the conveyor belt 210 drives the at least two baffles 220 to move; the at least two baffles 220 are used to output the products 300 produced by the product production equipment in sequence according to preset equidistant intervals, and the controller is the phase determination device 100 provided in the second aspect, and the controller is used to adjust the phase of the at least two baffles 220 through the drive motor.

[0110] In other words, the drive motor of the uniformly spaced processing equipment drives the transmission belt, which in turn drives the movement of the barrier rod. The controller controls the drive motor to change the phase of the barrier rod, maintaining a dynamic balance between the phase difference between the product production equipment and the uniformly spaced processing equipment. This ensures that the product can enter the uniformly spaced processing equipment between the two barrier rods, that is, smoothly enter the uniformly spaced processing equipment.

[0111] It is understandable that the controller is the phase determination device provided in the second aspect, that is, the controller adjusts the phase of the equidistant processing device according to the method provided in the first aspect.

[0112] In one embodiment, the equidistant processing equipment may also include: a first encoder and a second encoder, wherein: the first encoder is used to record the rotation angle of the wheel cutting device of the product production equipment, and the second encoder is used to record the rotation angle of the at least two baffles of the equidistant processing equipment; the controller is specifically used to: collect the real-time rotation angle recorded by the first encoder and the real-time rotation angle recorded by the second encoder, and subtract the real-time rotation angle recorded by the first encoder and the real-time rotation angle recorded by the second encoder to obtain the real-time phase difference.

[0113] That is, the rotation angle of the first encoder and the rotation angle of the second encoder are collected, and the difference between the two is taken to obtain the above-mentioned real-time phase difference. In fact, in addition to the real-time phase difference, the first phase difference can also be determined based on the first encoder and the second encoder.

[0114] It is understandable that the equally spaced processing equipment can also include a first sensor and a second sensor. The first sensor is used to determine the operating speed of the product production equipment, and the second sensor is used to determine the operating speed of the equally spaced processing equipment. When both are in a uniform speed state, the first phase difference can be determined based on the rotation angle of the first encoder and the second encoder.
