Description

Technical field:

[0001] The invention relates to the technical field of door and window gluing, and in particular to a decreasing cantilever gluing method. Background technology:

[0002] At present, there are two main ways to glue doors and windows: one is the single-piece glue method, that is, a piece of door and window is installed on the glue equipment for glueing, the door and window is removed after the glueing is completed, and then the next piece of door and window is installed on the glue equipment for glueing. The typical representative of this type of glue equipment is the horizontal automatic glue machine. The specific structure can refer to the patent previously applied by our company (patent name: a double-station automatic glue machine, authorization announcement number CN209866524U). Of course, some peers including our company have also improved and optimized the horizontal automatic glue machine, such as a double-head automatic glue machine previously applied by our company (authorization announcement number: CN209866523U), a door and window lifting workbench for automatic glue machines (authorization announcement number: CN211802091U), etc. Although these improvements have further improved the glue efficiency and / or glue quality, the glue method still uses a single-piece glue method. The biggest disadvantage of this glue method is that each piece of door and window needs to be installed and disassembled once, which seriously restricts the further improvement of the glue efficiency of doors and windows. The other is the stacking glue method, that is, after a piece of door and window is glued on the glue equipment, it is not unloaded, but the next piece of door and window is placed directly on top of it to continue gluing. When the set number of doors and windows is reached, the stacked (stacking) doors and windows can be directly removed by a forklift. A typical representative of this type of glue equipment is the stacking cantilever glue machine (also called cantilever glue machine or stacking glue machine). For the specific structure, please refer to the stacking full-automatic door and window glue machine previously applied by our company (authorization announcement number: CN219003544U). Compared with the single-piece glue method, the stacking glue method effectively saves the time of frequent unloading, thereby improving the efficiency of door and window glueing.

[0003] After the promotion and application in recent years, the stacking type glue machine has been recognized and praised by most users. Of course, many users have also given some good suggestions. One of them is that although the existing stacking type glue machine has achieved the goal of not needing frequent unloading, the loading still requires two people to complete it one by one, which undoubtedly limits the further improvement of the efficiency of door and window gluing. This drawback is more prominent when gluing doors and windows in batches. Usually, workers are required to take turns to glue, and the work intensity is high. In response to this suggestion, our company organized relevant scientific researchers to investigate the market demand and study the technical feasibility. At present, the door and window gluing industry is developing rapidly and steadily. If mechanized loading, gluing and unloading can be achieved on a gluing equipment, it can not only save manpower, but also improve the gluing efficiency. This is popular for both small and medium-sized door and window manufacturers and large door and window manufacturers. Of course, the existing door and window gluing production lines can also achieve mechanized loading, gluing and unloading. For example, a double-sided door and window gluing production line disclosed in a Chinese patent (authorization announcement number: CN117619671B) can also achieve mechanized gluing, but it occupies a large area, has a high selling price and high maintenance costs, and is not suitable for small and medium-sized enterprises. Through an in-depth analysis of the existing stacking automatic gluing machines, in order to achieve mechanized loading, only additional gantry loading manipulators or industrial robots can be added for loading, which undoubtedly significantly increases the cost and floor space, which is not conducive to promotion and application, and is not suitable for small and medium-sized door and window manufacturers. Therefore, it is necessary to develop a new gluing method and at the same time make adaptive improvements to the existing gluing equipment, so as to achieve automatic loading, gluing and unloading on one gluing equipment without significantly increasing the cost and floor space, saving labor and improving gluing efficiency.

[0004] It should be noted that the above contents belong to the technical knowledge of the inventor and do not necessarily constitute prior art. Summary of the invention:

[0049] In S1 , two gluing stations 2 are arranged at intervals on the cantilever gluing machine 1 , and two material unloading stations 5 are arranged on the cantilever gluing machine 1 correspondingly.

The three translations of the glue machine head 119 in space are realized, so as to meet the spatial freedom required for glueing the doors and windows 8. The gluing machine head 119 here belongs to the existing technology and is widely used in horizontal automatic gluing machines and stacking type gluing machines. In actual application, it will also be equipped with a glue supply system to supply glue to the gluing machine head 119. The gluing machine itself belongs to the existing technology. The innovation of this application lies in changing the loading and unloading method of doors and windows 8, thereby realizing mechanized loading, gluing and unloading.

[0051] Two brackets A3 are provided at intervals along the X-axis direction on the gluing station 2, and the brackets A3 are mounted on the frame 101. It is convenient to place the stacked multiple doors and windows 8 on the gluing station 2 using a forklift.

[0052] Two brackets B6 are arranged at intervals along the X-axis direction on the unloading station 5, and the brackets B6 are installed on the frame 1. It is convenient to stack the doors and windows 8 after gluing, and it is also convenient to use a forklift to take them out.

[0053] The positioning mechanism 4 includes a lifting guide rail 401 vertically arranged on the frame 1, a lifting beam 402 is slidably provided on the lifting guide rail 401, a lifting nut seat 403 and a lifting nut 404 are provided on the lifting beam 402, a lifting screw 405 is provided on the lifting nut 404, both ends of the lifting screw 405 are rotatably arranged on the frame 1 through seat bearings, the upper end of the lifting screw 405 is connected to the lifting motor 406 through a coupling, and the lifting motor 406 is vertically arranged on the frame 1, two correction brackets 407 are spaced apart on the lifting beam 402, a correction cylinder 408 is longitudinally provided on the correction bracket 407, and a correction push cylinder 408 is provided on the correction cylinder Plate 409, two rear positioning plates 410 are horizontally spaced on the lifting beam 402, side brackets 411 are respectively provided on both sides of the lifting beam 402, side plates 412 are rotatably provided on the side brackets 411, front pressing cylinders 413 are longitudinally provided on the side plates 412, front pressing cylinders 413 are provided with front top plates 414, a clamping mechanism is provided in the middle of the lifting beam 402, the clamping mechanism includes a guide rail A415 vertically arranged on the lifting beam 402, a slide seat A416 is provided on the guide rail A415, a clamping cylinder 417 is vertically provided on the lifting beam 402, the clamping cylinder 417 is connected to the slide seat A416, and the slide seat A416 is longitudinally provided with a The guide rail B418 is provided with a slide B419, and the slide A416 is longitudinally provided with a telescopic cylinder 420, which is connected to the slide B419, and the slide B419 is provided with a pressing plate 421, and the pressing plate 421 is provided with a U-shaped mounting hole 422, and the extension length of the pressing plate 421 can be manually adjusted to meet the clamping requirements of doors and windows 8 of different specifications; when positioning the door and window 8, the correction cylinder 408 is started, and the correction cylinder 408 pushes the door and window 8 to be positioned forward through the correction push plate 409 so that the distance between the rear end of the door and window 8 and the rear positioning plate 410 is greater than zero (here the distance is usually 2 to 5 mm, mainly to ensure that the rear positioning plate 410 does not fall when it descends Will interfere with the door and window 8 below), after the correction is completed, the correction cylinder 408 is reset, and the lifting motor 406 is started. The lifting motor 406 drives the lifting beam 402 to descend through the lifting screw 405, the lifting nut 404 and the lifting nut seat 403. The lifting beam 402 descends and drives the rear positioning plate 410, the front tightening cylinder 413 and the clamping mechanism to descend to the height corresponding to the door and window 8, and the front tightening cylinder 413 is started. The front tightening cylinder 413 longitudinally tightens the door and window 8 on the rear positioning plate 410 through the front top plate 414, and the telescopic cylinder 420 is started to drive the pressing plate 421 to extend, and the clamping cylinder 417 is started to drive the pressing plate 421 to vertically press on the frame 802 of the door and window 8 to complete the positioning of the door and window 8. In the past, the stacking type glue machine adopted the method of gluing from bottom to top, so each time the rear positioning plate is in place first and then the door and window are placed, so there will be no problem of interference between the door and window and the rear positioning plate.When the decreasing cantilever glue application method of the present application is used for glue application, it is necessary to first place the stacked multiple doors and windows 8 on the glue application station 2, and glue application is required from top to bottom. Therefore, when the rear positioning plate 410 is lowered, there are doors and windows 8 below it. Since the stacking of doors and windows 8 is not very standardized in actual production and the doors and windows 8 may be misplaced during forklift transportation, this may cause the doors and windows 8 below to block the rear positioning plate 410 from descending, and thus it is impossible to achieve top-down positioning glue application. For this reason, the present application specially designs a correction mechanism, and first corrects the doors and windows 8 through the correction cylinder 408 (pushing the doors and windows 8 that may block the rear positioning plate 410 from descending forward to ensure that there is no obstruction), ensuring that the rear positioning plate 410 can smoothly descend to position the next door and window 8. The positioning and clamping of the doors and windows is achieved as a whole, ensuring that the glue application can proceed smoothly.

[0054] The upper end of the lifting beam 402 is provided with a guide rail seat 423 in the horizontal direction, and an adjustment guide rail A424 is provided on the guide rail seat 423, and an adjustment slide A425 is provided on the adjustment guide rail A424, and a locking handle A426 is provided on the adjustment slide A425. The side bracket 411 is longitudinally arranged on the adjustment slide A425, and an adjustment guide rail B427 is longitudinally arranged on the side wall of the side bracket 411, and an adjustment slide B428 is provided on the adjustment guide rail B427, and a locking handle B429 is provided on the adjustment slide B428. The side plate 412 is rotatably arranged on the adjustment slide B428 through a hinge 430. The lateral and longitudinal positions of the front tightening cylinder 413 in the space are manually adjusted to meet the positioning requirements of doors and windows of different specifications. The manual adjustment is adopted mainly because the number of adjustments in time applications is small and the cost can be effectively reduced.
