Description

Technical Field

[0001] The present invention belongs to the technical field of methods, and in particular relates to an automatic confirmation method for the auxiliary phase of a tobacco packaging machine. Background Art

[0002] The tobacco packaging machine's auxiliary equipment is responsible for processes such as adding small transparencies to small boxes, adding strips to small boxes, and adding strip transparencies to strip boxes. The equipment has a high degree of automation. In common models, such as ZB45 (widely used in GDX2 units), coaxial mechanical phase control is used to synchronize the movements of all mechanical components of the auxiliary equipment, and does not require excessive program intervention. Therefore, except for the original MicroII, no common controller interfaces are provided.

[0003] In recent years, the tobacco industry has begun to require the installation of information components on packaging machines to achieve functions including barcode tracking and quality traceability. There is also an increasing demand for adding electronic control devices to packaging machines. At this time, the implementer usually obtains the phase of the original encoder of the packaging machine auxiliary machine to collect the equipment running rhythm position, and uses it to realize the synchronous collection and processing of the information system. The packaging machine auxiliary machine has 10 fixed working positions, corresponding to the ten possible positions of the small box in the strip box. The phase value of each position will be fixedly different by 36°. In this case, the phase value of the initial position needs to be obtained to calculate the values ​​of the 10 phases to complete the implementation. However Due to mechanical installation maintenance, encoder repair and other reasons, the initial phase value of each unit will be different, and may change after each maintenance. Therefore, after each maintenance, it is necessary to manually re-acquire the phase information. The phase modification requires updating the control system before it can be restored to use. This manual method of obtaining phase information can meet certain usage requirements, but it also has major defects. Manual acquisition is inefficient, labor-intensive, and labor-costly, affecting the normal operation and production efficiency of the equipment. It also greatly increases the complexity of maintenance operations and may introduce errors. The equipment is prone to failure and cannot effectively meet production and practical requirements. Summary of the Invention

[0004] To solve the problems of low efficiency, high labor intensity, high labor cost, affecting the normal operation and production efficiency of the equipment, greatly increasing the complexity of maintenance operations, and possibly introducing errors, making the equipment prone to failure, and failing to effectively meet production and practical requirements in the above-mentioned existing technologies;

[0005] The present invention provides a method for automatically confirming the phase of an auxiliary machine of a tobacco packaging machine, comprising the following steps: 1) pre-determining the phase value; during one revolution of the equipment (10 working phases), the turret rejection station will pass through 5 times; the rejection will be switched to manual mode; and the equipment will trigger 5 rejection actions during one revolution. Between each two rejection actions, there is a fixed interval of 72° (144 scales when a 10-bit precision encoder is used); the angle (phase) value of a certain rejection action is recorded as T0; and an offset value i (unknown at this time) is set, so that 10 working phases can be obtained in sequence as Pn (when n is 1-9) = Pn-1+36°, where P0 = T0+i; in particular, if a certain P value exceeds the value range (for example, [0°+i, 360°+i)), it needs to be increased or decreased by 360° to meet the value range. Value range requirements; 2) Determination of offset value and phase value. During one revolution of the equipment, the strip box rejection station will pass through once, and the rejection will be switched to manual mode. One revolution of the equipment will trigger one rejection action, and the angle (phase) value of the rejection action will be recorded as T1. Each device has a fixed positioning value n (0-9). Let Pn=T1, so that i and all 10 P values ​​can be determined; 3) Automatic learning. When necessary, switch the additional control system to "learning mode" and specify this n value (usually unchanged). Switch the rejection to manual mode and manually turn the wheel until the turret is rejected at least once and the strip box is rejected at least once. The automatic learning of 10 phase values ​​can be completed; 4) Phase value storage and application. The auxiliary control system of the packaging machine should save the phase value and apply it directly after exiting the learning mode.

[0006] The beneficial effects of the present invention are: the phase value is pre-determined by turret rejection in manual mode, the offset value and all phase values ​​are determined in the box rejection state, and it is supplemented by automatic learning and saving functions. It does not require manual acquisition, has high efficiency, low labor intensity, and low labor cost, and does not affect the normal operation and production efficiency of the equipment. At the same time, it also greatly reduces the complexity of maintenance operations, is not easy to introduce errors, and the equipment is not prone to failure, which can effectively meet production and practical requirements. DETAILED DESCRIPTION

[0007] The preferred embodiments of the present invention are described in detail below so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more precise definition of the protection scope of the present invention.

[0008] The present invention provides a method for automatically confirming the phase of an auxiliary machine of a tobacco packaging machine, comprising the following steps: 1) pre-determining a phase value; during one revolution of the equipment (10 working phases), the turret rejection station passes through it five times; switching the rejection mode to manual mode; and triggering five rejection actions during one revolution of the equipment. A fixed interval of 72° (144 scale divisions when a 10-bit precision encoder is used) is set between each rejection action; the angle (phase) value of a particular rejection action is recorded as T0; and an offset value i (currently unknown) is set. The 10 working phases obtained are Pn (when n is 1-9) = Pn-1 + 36°, where P0 = T0 + i. In particular, if a P value exceeds a value range (e.g., [0° + i, 360° + i)), it needs to be increased or decreased by 360° to meet the value range requirement;

[0009] 2) Determine the offset and phase values. During one revolution of the device, the strip box rejection station will pass through once. Switch the rejection mode to manual mode, and trigger one rejection action once per revolution of the device. The angle (phase) value of the rejection action is recorded as T1. Each device has a fixed positioning value n (ranging from 0 to 9). Let Pn = T1, so that i and all 10 P values ​​can be determined. Assuming that the positioning value n of the device is 0, then P0 = T1. Then, according to P0 = T0 + i in step 1, where T0 is known, the i value can be calculated, and all 10 phase values ​​can also be calculated.

[0010] 3) Automatic learning: When necessary, switch the additional control system to "learning mode" and specify the n value (usually unchanged). Switch the rejection mode to manual mode and manually turn the machine until the turret rejects at least once and the box rejects at least once. This completes the automatic learning of 10 phase values.

[0011] 4) Phase value preservation and application: The packaging machine auxiliary control system should save the phase value and apply it directly after exiting the learning mode.

[0012] Common packaging machine auxiliary equipment will automatically reject the turret at least once and the box at least once when the machine is started. Therefore, automatic correction can be performed every time the machine is started to reduce the deviation caused by unplanned maintenance of the equipment.

[0013] The beneficial effects of the present invention are: the phase value is pre-determined by turret rejection in manual mode, the offset value and all phase values ​​are determined in the box rejection state, and it is supplemented by automatic learning and saving functions. It does not require manual acquisition, has high efficiency, low labor intensity, and low labor cost, and does not affect the normal operation and production efficiency of the equipment. At the same time, it also greatly reduces the complexity of maintenance operations, is not easy to introduce errors, and the equipment is not prone to failure, which can effectively meet production and practical requirements.

[0014] The above embodiments do not limit the product form and style of the present invention. Any appropriate changes or modifications made by ordinary technicians in the relevant technical field should be deemed to be within the patent scope of the present invention.
