Description

Technical Field

[0001] The present invention relates to the technical field of plate processing equipment, and in particular to an unmanned automatic material replacement edge sealing system and method. Background Art

[0002] At present, edge banding machines are mainly used as mechanical equipment in the furniture manufacturing industry, and are mainly used to perform edge banding on the edges of furniture panels. Furniture panels are usually made of natural panels, artificial panels or other materials. The edges are easily damaged by moisture, mold or collision, and the edges of the panels need to be edge banded. The utility model patent with the Chinese patent publication number CN204487748U discloses an "automatic edge banding machine edge banding switching device" that can store more than two rolls of edge banding at a time. After a roll of edge banding is used up, it automatically switches, but its empty disc needs to be manually unloaded and replenished with a new disc, resulting in a short shutdown of the equipment, and the disc replacement cycle is long (about 3 to 5 minutes / time), which cannot meet the needs of high-density production lines. In addition, the patent does not integrate the material disc balance monitoring function, and relies on manual judgment of the disc replacement timing, which is prone to disc replacement lag or misjudgment problems, and adopts a single-row guide track design. Although the edge band switching can be realized, the path conflict is prone to cause material accumulation when multiple specifications of edge banding are processed in parallel.

[0003] Therefore, the existing edge banding machines have the following shortcomings: first, they cannot automatically switch the edge banding according to the requirements of the board; second, they cannot adapt to the automated mass production process; third, the production efficiency is low, and workers need to manually change the materials every time a board is changed; fourth, the edge banding cannot be automatically replenished after it is used up, which easily causes production suspension. Summary of the invention

[0004] Purpose of the invention: The purpose of the present invention is to provide an unmanned automatic material changing edge banding machine system. By setting up an automatic material changing device, this solution can realize the automatic switching of material trays when the edge banding machine material is exhausted, ensuring continuous production operation.

[0008] Furthermore, the tape cutting assembly includes a mounting frame, a hydraulic device and a cutter, and the hydraulic device drives the cutter to move vertically along the auxiliary notch of the mounting frame to complete the fixed-length cutting of the edge banding tape.

[0009] Furthermore, the material grid includes a standby grid and an empty grid arranged side by side, the standby grid is used to store unused material trays, and the empty grid is used to recover exhausted material trays. The standby grid is placed in front of the sliding track, and the empty grid is placed on the side of the standby grid, perpendicular to the standby grid, and anti-slip pads are provided at the bottom of both grids.

[0010] Furthermore, the encoder is built into the guide wheel of the guide assembly, and the use length of the edge band is calculated by recording the number of rotations of the guide wheel, and the data is transmitted to the PLC control system in real time.

[0033] The technical solution of the present invention is further described below in conjunction with the accompanying drawings.

[0034] like Figure 1-13 As shown, an unmanned automatic material changing edge banding machine system and method of the present invention comprises a main carrier board 1, a mechanical claw assembly 9 and a material grid 10. A heating assembly 4, a belt cutting assembly 6, a belt guide assembly 5 and a guide assembly 7 are sequentially arranged on the top of the main carrier board 1, and a reversing assembly 8, a disk changing assembly 2 and a material disk 41 are fixed to the outer end of the main carrier board 1. The above-mentioned guide assembly 7, belt cutting assembly 6, belt guide assembly 5 and heating assembly 4 are all installed at a designated position on the top of the main carrier board 1 through a fixed connector.

[0035] The side end of the material tray 41 is equipped with a guide wheel assembly 61, which is installed at the belt outlet of the material tray 41 to ensure that the edge banding can be smoothly output. The bottom of the material tray 41 is designed with a specific angle of the bayonet to ensure that the belt outlet of the edge banding always maintains the correct direction during the production process.

[0036] The reversing assembly 8 is installed above the outlet of the material tray 41. Due to the limitation of the installation angle and space utilization, the material tray 41 is fixed in a vertical direction on the tray changing assembly 2. When the edge band is output from the material tray 41, its direction is horizontal. After passing through the reversing assembly 8, the edge band is converted from a horizontal state to a vertical state, which is convenient for subsequent cutting and conveying.

[0037] A guide assembly 7 is installed between the reversing assembly 8 and the tape cutting assembly 6. The guide assembly 7 is fixedly connected to the main carrier plate 1 through the bottom plate 23, and uses the motor guide wheel 22 to realize the forward and backward movement of the edge band, including the feeding and retracting operations. In addition, the guide assembly 7 has a built-in encoder 21 for real-time recording of the use length of the edge band, so as to output the edge band length matching the requirements of different plates and monitor the use of the material tray 41.

[0038] The tape cutting assembly 6 is composed of a mounting frame 51, a hydraulic device 52, a cutter head 53 and a notch 54. After the guide assembly 7 outputs the edge banding to a predetermined length according to the setting, the hydraulic device 52 drives the cutter head to complete the precise cutting operation of the edge banding. In order to improve the cutting accuracy, an auxiliary notch 54 matching the cutter head 53 is provided in the mounting frame 51.

[0039] After cutting, the edge banding enters the belt guide assembly 5, which provides the conveying power. The belt guide assembly consists of a base 32 and an electric guide wheel 31, which is fixedly installed after the belt cutting assembly 6 to ensure that the edge banding can smoothly enter the next process.

[0040] The heating component 4 is installed between the tape guide component 5 and the tape feed reel 3. When the edge banding tape passes through the heating component, it is heated by the heater to soften the glue, thereby improving the adhesion effect of the edge banding tape and ensuring the quality of subsequent processing.

[0041] The tape feeder 3 is fixed to the rear side of the main carrier plate 1. The edge banding tape enters the tape feeder after passing through the heating assembly. A partition 72 is designed inside the tape feeder to limit the edge banding tape to run along a predetermined track, and then enter the edge banding machine for edge banding processing.

[0042] The disc changing assembly 2 drives the turntable 43 to rotate through the motor 42, which is rotatably connected to the main carrier plate 1, and is used to switch the material disc 41. When the encoder 21 in the guide assembly 7 detects that the edge band in the current material disc 41 is nearly exhausted, the PLC system sends a control signal to drive the motor 42 to rotate the turntable 43, and switch the new material disc 41 to the bottom of the reversing assembly 8, so as to realize the continuous supply of the edge band.

[0043] The sliding track 81 is installed on the front side of the main carrier 1, and the mechanical claw base 83 moves through the sliding track 81, and drives the mechanical claw 82 to complete the grabbing operation. When the turntable 43 completes the switching, the empty material tray 41 moves to the lower side of the turntable 43. At this time, the mechanical claw 82 grabs the empty tray and places it in the empty tray grid 91 in the stacking grid 10, and at the same time grabs a new material tray 41 from the standby grid 92 and installs it on the turntable 43, completing the automatic replacement of the material tray 41.

[0044] The stacking grid 10 is arranged in front of the sliding track 81, and includes a standby grid 92 and an empty grid 91. When the empty material tray on the turntable 43 is removed by the mechanical claw 82, it is placed in the empty grid 91, and the new material tray in the standby grid 92 is grabbed by the mechanical claw 82 and installed on the turntable 43, realizing the full process automatic loading and unloading operation.
