Description

Technical Field

[0001] The present invention relates to the field of coding and identification of intelligent machines, and in particular to a system and method for associating a small box serial code with a large box serial code. Background Art

[0002] At present, the more common methods for the collection and association of small box serial codes and large box serial codes are as follows: Figure 1 and Figure 2 As shown. Figure 1 In the S4 serialization association system, in order to read and associate the small box serial code with the large box serial code, the S3 small box serial code reader first collects the small box serial codes one by one and sends them to the S4 serialization association system to form a small box serial code queue. If the small box serial code collection fails, it will be automatically removed by S5; then the S4 serialization system will follow the preset number of small boxes in the large box, and sequentially take the corresponding number of small box serial codes from the small box serial code queue and associate them with the large box serial code. Figure 2 In the process, the S4 serialization association system needs to realize the reading and association of the small box serial code and the large box serial code. First, the S3 small box serial code reader group collects the small box serial code in a whole row or a whole layer and sends it to the S4 serialization association system to form a small box serial code queue. Then, the S4 serialization system will take the corresponding number of small box serial codes from the small box serial code queue in order according to the number of small boxes in the large box or the full box signal of the packing machine to associate with the large box serial code. If the S3 small box serial code reader group fails to collect any small box code, it will cause the association to fail, and the whole box will be rejected after the small box is packed.

[0003] There are two existing serial code association methods for large box stacking. Figure 1 The method requires a small box single box reading and rejection conveyor line, which has high equipment investment cost and takes up space; the distance from the small box serial code reading to the packing link is far, and there are many uncontrollable factors that will cause errors in the small box serial code queue, resulting in errors in the association of the small box serial code and the large box serial code; in order to prevent the small box serial code and the large box serial code from being recognized by people after the errors, it is necessary to add a corresponding association verification reader to the packing machine, which leads to increased costs; even with the existence of an association verification reader, it cannot guarantee 100% association accuracy. Once the verification fails, it can only be handled through a shutdown alarm, which reduces the continuity of the entire line operation and affects production efficiency. As for Figure 2 The method requires multiple readers to form a small box reader group or a high-pixel camera, which is costly and requires a high installation space. It also has requirements for the position, placement, and packing of the small box serial code, and its applicability is limited.

[0004] Based on this, the embodiments of this specification provide a system and method for associating a small box serial code with a large box serial code. Summary of the invention

[0005] The present invention provides a system and method for associating the serial numbers of small boxes with those of large boxes to solve the following problems: There are two existing methods for associating serial numbers for large box stacking. Among them, Figure 1 For the method of [description of the first method], a small box single-box reading, rejection, and conveying line is required, resulting in high equipment investment costs and large space occupation; the distance from the small box serial number reading to the packing link is relatively long, and there are many uncontrollable factors that can cause errors in the small box serial number queue, thus leading to errors in the association between the small box serial number and the large box serial number; in order to prevent errors in the small box serial number and the large box serial number from being unrecognizable by people, a corresponding association verification code reader needs to be added to the packing machine, resulting in increased costs; even with the existence of the association verification code reading, it cannot guarantee 100% accurate association. Once the verification fails, only abnormal handling can be carried out through shutdown alarm, reducing the coherence of the whole line operation and affecting production efficiency. And for Figure 2 For the method of [description of the second method], the small box code reader group requires multiple code readers or high-pixel cameras to form a code reader group, with relatively high costs and high requirements for installation space; there are requirements for the position, placement form, and packing method of the small box serial number, and the applicability is limited.

[0006] An association system for the serial numbers of small boxes and large boxes according to the present invention includes:

[0007] A small box serial number code reader, a PLC output signal, a small box pushing mechanism, a box blocking mechanism, a small box stacking mechanism, an automatic packing machine, and a host computer;

[0008] Among them,

[0009] The small box serial number code reader is used to read the small box serial numbers and collect the small box serial numbers on the conveying line to form a small box serial number sequence;

[0010] The PLC output signal groups the small box serial number sequence based on the received signal type of the automatic packing machine to generate a serial number grouping sequence;

[0011] The host computer associates the serial number grouping sequence with the large box serial number in sequence based on a preset number of small box serial numbers;

[0012] The small box pushing mechanism is used to convey the small boxes as a whole layer;

[0013] The box blocking mechanism is used to send the small boxes as a whole layer into the automatic packing machine for packing;

[0014] The small box stacking mechanism is used to stack the small boxes as a whole layer layer by layer in sequence;

[0015] The automatic packing machine is used to realize the automatic packing of the packaged products.

[0016] A method for associating the serial number of a small box with the serial number of a large box according to the present invention includes the following steps:

[0017] Obtain the small box serial number sequence;

[0018] Based on the signal type received from the automatic cartoning machine, group the small box serial number sequence to generate a serial number grouping sequence;

[0019] Based on the preset number of small box serial numbers, associate the serial number grouping sequence with the large box serial number in sequence.

[0020] The system and method for associating the serial number of a small box with the serial number of a large box according to the present invention can save the cost of code reading and association, achieve a success rate of reading the small box serial number, which can be increased from 95% to 99.99%, and can ensure that the association accuracy rate of the small box serial number and the large box serial number reaches 100%. This association system and method are not restricted by the position of the traceability code and the cartoning method, and the application scenario is more flexible, and it can also be applied to the scenario of large box palletizing.

[0025] Embodiment 1. A system for associating the serial number of a small box with the serial number of a large box, see Figure 3 as shown, including:

[0026] A small box serial number reader S3, a PLC output signal, a small box pushing mechanism S8, a box blocking mechanism S5, a small box stacking mechanism S7, an automatic cartoning machine S9, and a host computer S4;

[0027] Among them,

[0028] The small box serial number reader is used to read the small box serial numbers on the small boxes on the collection and conveying line to form a small box serial number sequence;

[0029] The PLC output signal groups the small box serial code sequences based on the signal types received from the automatic cartoning machine, generating a serial code grouping sequence;

[0030] The host computer S4 associates the serial code grouping sequence with the large box serial code in sequence based on the preset number of small box serial codes;

[0031] The small box pushing mechanism S8 is used to convey the small boxes as a whole layer;

[0032] The box blocking mechanism S5 is used to send the small boxes as a whole layer into the automatic cartoning machine for cartoning;

[0033] The small box stacking mechanism S7 is used to stack the small boxes as a whole layer layer by layer in sequence;

[0034] The automatic cartoning machine S9 is used to realize the automatic cartoning of the packaged products.

[0035] In the embodiment of this specification, the association system further includes: an electric eye S3-1;

[0036] The electric eye is used to detect the small boxes on the small box serial code acquisition conveyor line;

[0037] When the electric eye detects a small box, the PLC output signal triggers the small box serial code reader to start reading the small box serial code until the small box serial code reader receives the end signal sent by the PLC output signal, generating the small box serial code sequence.

[0038] In the embodiment of this specification, the signal types of the automatic cartoning machine include: the pushing signal of the small box pushing mechanism, the full layer signal of the automatic cartoning machine, and the full box signal of the automatic cartoning machine.

[0039] In the embodiment of this specification, the PLC output signal groups the small box serial code sequences based on the signal types received from the automatic cartoning machine, generating a serial code grouping sequence, specifically including:

[0040] When the PLC output signal is based on the received pushing signal of the automatic cartoning machine, it starts to receive the small box serial code, forming the small box serial code sequence;

[0041] When the PLC output signal is based on the received full layer signal of the automatic cartoning machine, the small box serial code sequence forms a full layer serial code sequence;

[0042] When the PLC output signal is based on the received full box signal of the automatic cartoning machine, several layers of the full layer serial code sequences form a full box serial code sequence, and the full box serial code sequence is the serial code grouping sequence.

[0043] In a specific embodiment, different layers of small boxes can be realized according to the types of signals received by the PLC output signal. Specifically, when a full-layer signal is received, the corresponding small box is considered as one layer, and the small box sequence code corresponding to one layer of small boxes is used as the sequence code sequence of the whole layer. Similarly, when a full-box signal is received, it is considered that all small boxes can fill a box, that is, several layers form a box, and the sequence code sequence of the whole layer forms the sequence code sequence of the whole box.

[0044] In the embodiment of this specification, the sequence code sequence of the whole layer is a sequence set formed by the small box sequence code and the layer number where the small box is located;

[0045] The sequence code sequence of the whole box is a sequence set formed by several sequence code sequences of the whole layer, and the small box packages corresponding to the several sequence code sequences of the whole layer are packed into a large box.

[0046] In the embodiment of this specification, the association system further includes:

[0047] If the number of the small box sequence code sequences is less than the preset number of small box sequence codes, the host computer marks the current acquisition as failed, and the whole box corresponding to the small box sequence code sequence is excluded.

[0048] In the embodiment of this specification, the host computer automatically generates a padding code to mark the current acquisition as failed.

[0049] Specifically, the preset number of small box sequence codes is the number of small box sequence codes that can be received within a reading cycle. The number of small box sequence codes that can be received within a code reading cycle is specifically the number of small boxes required for packing.

[0050] A reading cycle is that the PLC output signal triggers the small box sequence code reader to start reading the small box sequence code until the small box sequence code reader receives the end signal sent by the PLC output signal, which is regarded as a reading cycle. The small box sequence codes read in this cycle are used as the sequence code sequence of the serial numbers.

[0051] Of course, for the association system of the small box sequence code and the large box sequence code without an electric eye, the small box sequence code reader is in the normally open mode. The S3 small box sequence code reader reads the code as soon as it sees the code, and the small box sequence codes collected each time are sent to the S4 sequence code association system in real time for sorting. Finally, the S4 sequence code association system receives signals (S8 pushing signal / S9 full-layer signal of the automatic packing machine / S9 full-box signal of the automatic packing machine) sent by the S9 automatic packing machine from the PLC to perform data cutting and data grouping and sorting. In the case of gapless operation of products for packing or palletizing, a low-pixel reader can also be used to collect single codes. The code reading method of the small box sequence code is specifically determined according to the application business scenario.

[0052] The correlation system for the carton serial number and the big box serial number of the present invention can save the costs of code reading and correlation, achieve the success rate of carton serial number reading, which can be increased from 95% to 99.99%, and can ensure that the correlation accuracy rate of the carton serial number and the big box serial number reaches 100%. This correlation system and method are not restricted by the position of the traceability code and the packing method, with a more flexible application scenario, and can also be applicable to the scenario of big box palletizing.

[0053] Embodiment 2: A method for correlating the carton serial number and the big box serial number can be implemented by using the correlation system for the carton serial number and the big box serial number in Embodiment 1 above. Refer to Figure 4 as shown, and includes the following steps:

[0054] Step S401: Obtain the carton serial number sequence;

[0055] Step S403: Based on the signal type received from the automatic cartoning machine, group the carton serial number sequence to generate a sequence code grouping sequence;

[0056] Step S405: Based on the preset number of carton serial numbers, correlate the sequence code grouping sequence with the big box serial number in sequence.

[0057] In the embodiments of this specification, the correlation method further includes:

[0058] Step S407: The carton serial number sequence is formed by the carton serial number reader starting to read the carton serial number when the electric eye detects the carton, triggered by the PLC output signal, until the carton serial number reader receives the end signal sent by the PLC output signal. The carton serial numbers read during this process are formed.

[0059] The method for correlating the carton serial number and the big box serial number of the present invention can save the costs of code reading and correlation, achieve the success rate of carton serial number reading, which can be increased from 95% to 99.99%, and can ensure that the correlation accuracy rate of the carton serial number and the big box serial number reaches 100%. This correlation system and method are not restricted by the position of the traceability code and the packing method, with a more flexible application scenario, and can also be applicable to the scenario of big box palletizing.
