Description

Technical Field

[0001] The invention belongs to the technical field of edge band switching of edge banding machines, and in particular relates to a method for controlling the switching of edge bands of edge banding machines. Background Art

[0002] Edge banding machines are widely used in the production of panel furniture, cabinets, wardrobes and other wooden products. In traditional edge banding operations, changing the edge band is a tedious and time-consuming task that requires operators to perform frequently. Manual intervention will increase production instability, ultimately leading to low production efficiency and increased costs.

[0003] With the development of science and technology, intelligent edge banding machines have emerged. In the intelligent edge banding machine system, automatic switching of edge bands is one of the core functions. Its application has greatly improved production efficiency and flexibility.

[0004] In the prior art, in a fully automatic production line, the intelligent edge banding machine can form a complete production line with other intelligent equipment to realize the continuous operation of automatic feeding, edge banding, trimming, inspection and other processes of the board. In this process, the edge banding machine of the prior art cannot automatically switch the edge banding to adapt to the processing requirements of different boards.

[0005] To this end, the present invention provides an intelligent algorithm for automatically switching sidebands. Summary of the invention

[0006] The object of the present invention is to overcome the deficiencies of the prior art and provide an edge band switching control method for an edge banding machine capable of automatically switching edge bands.

[0007] The technical solution of the present invention is as follows:

[0008] A method for controlling the switching of edge bands of an edge banding machine comprises the following steps:

[0009] S1: installing a plurality of sidebands in the channel of the tape feeding mechanism, and detecting the presence or absence of the sidebands through a detection switch in the tape feeding mechanism, wherein the sideband information is set in the corresponding channel information of the host computer, and the channels of the tape feeding mechanism are arranged in a front-to-back order to form channel numbers;

[0010] S2: The host computer confirms the current required sideband information based on the board information;

[0011] S3: judging whether the sideband information in the tape feeding mechanism is the same as the current sideband information according to the multiple sideband information in the channel information corresponding to the tape feeding mechanism and the required sideband information; if they are the same, adding them to the channel set List;

[0012] S4: Calculate the start channel number and the next channel number according to the channel set List obtained in step S3. If the number of elements in the channel set List in step C is 0, it means that all the sideband information of the tape feeding mechanism is different from the current required sideband information. In this case, the start channel number and the next channel number are both 0. If the number of elements in the channel set List is not 0, it means that all the sideband information of the tape feeding mechanism is the same as the current required sideband information. In this case, the start channel number is not 0. If the number of elements in the channel set List is 1, the next channel number is 0. If the number of elements in the channel set List is greater than 1, the next channel number is also not 0.

[0013] S5: According to the result of step S4, if the values ​​of the start channel number and the next channel number are not 0, they are the sideband channel numbers;

[0014] S6: If the current channel number is the same as the start channel number, it means that there is no need to switch channels, and step S9 is executed; if the current channel number is different from the start channel number, step S7 is executed;

[0015] S7: withdraw the sideband of the current channel, and then send the sideband in the start channel number to the processing station;

[0016] S8: Determine whether the sideband switching action is successful. If successful, execute step S9; if unsuccessful, execute step S10;

[0017] S9: perform subsequent edge banding processing;

[0018] S10: Sideband switching fails and the device alarms.

[0019] Further, the host computer channel information in step S1 is saved in the database, and the sideband detection switch signal disappears, indicating that the corresponding channel sideband has been used up, and the corresponding channel information in the host computer is automatically set to null.

[0020] Furthermore, in step S2, the demand sideband information is saved in the database, and the previously saved demand sideband information is automatically loaded after the host computer is restarted.

[0021] Furthermore, the channel information in the channel set List in step S3 is sorted in descending order according to the used length of the sideband.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. The present invention realizes the detection of the sideband through step S1, which is convenient for the collection of sideband information, and realizes the confirmation of the currently required sideband information through step S2, then realizes the acquisition of the usable sideband information through steps S3 and S4, and realizes whether the sideband is correct under the judgment of step S5, and finally realizes the switching of the sideband through steps S6-S7, thereby realizing automatic switching of the sideband.

When the sideband on the sideband channel in use is about to run out, the sideband detection switch will send a signal, and the host computer will immediately start the automatic tape changing program, that is, call the intelligent algorithm for switching sidebands to achieve seamless switching. Here, 12 channels are taken as an example, and the channel numbers are 1, 2, 3...12 respectively.

[0040] Sideband information: usually includes sideband name, sideband thickness and sideband color.
