Description

Technical Field

[0001] The utility model relates to the technical field of edge banding machines, in particular to an auxiliary conveying device for edge banding machines. Background Art

[0002] Edge banding is an important process in the manufacturing process of panel furniture. The quality of edge banding directly affects the quality, price and grade of the product. At present, the automatic edge banding feeding is to set an inclined pressure wheel on the side close to the reference surface of the edge banding machine, and cooperate with the inclined roller below to make the board close to the reference surface of the edge banding machine while feeding it into the edge banding machine. The existing automatic feeding mechanism has a good feeding effect when the length and width ratio of the board is small, but when the length and width ratio of the board exceeds 1:6 (for example, a 300mm wide board with a length of more than 2100mm), the conveying roller below needs to use an inclined roller to make the board move close to the reference surface. At this time, it is difficult to prevent the board from swinging only by the inclined pressure wheel at the end. If the board is slightly skewed during edge banding feeding, it will cause edge banding failure. In addition, if the edge banding machine has a pre-milling function, it may even cause the board to be scrapped. Utility Model Content

DETAILED DESCRIPTION

[0031] The words expressing positions and directions described in the present utility model are all explained by taking the drawings as examples, but they can be changed as needed, and all the changes are included in the protection scope of the present utility model.

[0032] like Figure 1-11 , is an auxiliary conveying device for an edge banding machine provided by the utility model, comprising a conveying mechanism 21, a pressing wheel mechanism 22, a side push and aligning mechanism 23, a push mechanism 24 and a blocking mechanism 25, wherein the side push and aligning mechanism 23 is located at one side of the conveying mechanism 21, the pressing wheel mechanism 22 is located above the conveying mechanism 21 and is arranged close to the side push and aligning mechanism 23, and the side of the conveying mechanism 21 is provided with the push mechanism 24 and the blocking mechanism 25, the push mechanism 24 is used to catch up with the plate, and when the plate contacts the blocking mechanism When the hand pushing mechanism 24 and the blocking mechanism 25 are in place, the hand pushing mechanism 24 and the blocking mechanism 25 cooperate with each other to clamp the plate and move along with the conveying mechanism 21. The side pushing and aligning mechanism 23 pushes the plate to align with the reference surface of the edge sealing device 30 when the hand pushing mechanism 24 and the blocking mechanism 25 clamp the plate. The pushing direction of the side pushing and aligning mechanism 23 is perpendicular to the conveying direction of the conveying mechanism 21. The pressing wheel mechanism 22 is used to press down the plate when the side pushing and aligning mechanism 23 pushes the plate so that the plate can smoothly enter the edge sealing device 30.

[0033] In this embodiment, in order to facilitate understanding of the working principle of the auxiliary conveying device 20, the auxiliary conveying device 20 is applied to the circulating edge sealing equipment for explanation. Fig.12, wherein the circulating edge banding equipment includes a control system, a first edge banding system electrically connected to the control system, a second edge banding system, a first rotating device 50 and a second rotating device 60, the output end of the first edge banding system and the input end of the second edge banding system are connected through the first rotating device 50, the output end of the second edge banding system and the input end of the first edge banding system are connected through the second rotating device 60, the first edge banding system and the second edge banding system both include a feeding device 10, an auxiliary conveying device 20, an edge banding device 30 and a discharging device 40 arranged in sequence, the first edge banding system and the second edge banding system are connected through the first rotating device 50 and the second rotating device 60, thus forming a path for circulating and rotating conveying of panels; The first rotating device 50 and the second rotating device 60 both include a steering bracket, and the steering bracket is provided with a grasping mechanism which can move back and forth between the discharging device 40 and the feeding device 10, and the grasping mechanism can rotate and rise and fall in the horizontal direction, wherein the grasping mechanism includes a lifting component, a rotating component and a suction component, the lifting component is slidably connected to the steering bracket, the rotating component is connected to the lifting component, the suction component is connected to the rotating component, the suction component includes two parallel adsorption plates, and a vacuum suction device for adsorbing the plate is provided at the bottom of the adsorption plate, the lifting component is used to drive the suction component to move up and down, and the rotating component is used to drive the suction component to rotate in the horizontal direction. Among them, the first edge banding system and the second edge banding system both include a feeding device 10, an auxiliary conveying device 20, an edge banding device 30 and a discharging device 40. Therefore, after the panel passes through the first edge banding system, the edge banding processing of one edge of the panel can be realized, and then the first rotating device 50 transports the panel coming out of the first edge banding system and returns it to the second edge banding system, and the second edge banding system performs edge banding processing on the other edge of the panel. Then, the second rotating device 60 transports the panel coming out of the second edge banding system and returns it to the first edge banding system, and continues to perform edge banding processing on the remaining edges of the panel, and so on. In this way, two edge banding devices 30 can be used to complete the needs of sealing one, two, three or four sides of the panel, and the edge banding can be switched at any side. It has high flexibility and can meet different edge banding requirements.In this embodiment, the auxiliary conveying device 20 is arranged between the feeding device 10 and the edge banding device 30, and the feeding device 10 inputs the plate into the auxiliary conveying device 20, and the plate is input into the edge banding device 30 through the auxiliary conveying device 20. In order to intelligently control the rhythm of the plate entering the auxiliary conveying device 20, a lifting and positioning mechanism is provided at the output end of the feeding device 10, a first sensor 26 is provided on the pressing wheel mechanism 22, and a second sensor 27 is provided on the pushing mechanism 24. When the first sensor 26 identifies the time when the first plate enters, if the rear plate does not reach the set time, the lifting and positioning mechanism responds to the signal of the first sensor 26 and blocks the rear plate from entering the conveying mechanism 21. After waiting for the set plate spacing to be met, the lifting and positioning mechanism releases the rear plate, and the rear plate enters the conveying mechanism 21 accordingly. In this way, the rhythm of the plate entering the conveying mechanism 21 can be well controlled, thereby ensuring that there is a certain safety distance between two adjacent plates to prevent mutual interference during edge banding; the pushing mechanism 24 and the blocking mechanism 25 are arranged when the plate enters the conveying mechanism 21 The plate will stay at a fixed position before entering the conveying mechanism 21 and passing through the second sensor 27, the pusher mechanism 24 will be ready to move. When the plate leaves the second sensor 27, after a certain delay, the pusher mechanism 24 responds to catch up with the plate and moves with the conveying mechanism 21. At the same time, the control system controls the blocking mechanism 25 to extend above the conveying mechanism 21 so that the plate contacts the blocking mechanism 25. When the plate contacts the blocking mechanism 25, the pusher mechanism 24 and the blocking mechanism 25 cooperate with each other to clamp the plate. And it moves along with the conveying mechanism 21. At the same time, the side push and alignment mechanism 23 will respond to the action. The side push and alignment mechanism 23 will push the plate to align with the reference surface of the edge sealing device 30, thereby ensuring that the plate enters the edge sealing device 30 accurately and stably for edge sealing. At the same time, the pressure wheel mechanism 22 will also follow the movement of the plate and press down the plate accordingly, thereby stabilizing the plate and avoiding the plate from jumping, ensuring that the plate moves forward smoothly. After the plate enters the edge sealing device 30, the push mechanism 24 and the blocking mechanism 25 will quickly reset to the starting position of the next plate.

[0034] In the above structure, the push mechanism 24 and the blocking mechanism 25 cooperate to clamp the plate to prevent the plate from shifting during the conveying process. At the same time, the side push alignment mechanism 23 cooperates to accurately align the plate with the edge banding machine reference and then convey it following the conveying mechanism 21. The plate is pressed by the pressure wheel mechanism 22 for conveying, so that the plate can be smoothly fed into the edge banding machine, which greatly improves the positioning and alignment accuracy of the plate, ensures that the plate accurately enters the edge banding device 30, is beneficial to improving the edge banding quality, and improves the feeding accuracy and feeding efficiency.

[0035] As a preferred embodiment, the pressing wheel mechanism 22 has several groups of roller pressing structures extending along the conveying direction of the conveying mechanism 21, each group of the roller pressing structures includes a plurality of liftable pressing rollers 2208, the axis of the rotating shaft of each pressing roller 2208 is perpendicular to the direction of the conveying mechanism 21, and the wheel surface of each pressing roller 2208 is tangent to the same plane to form a roller pressing surface.

[0036] In this embodiment, when the plate is clamped and conveyed by the push mechanism 24 and the blocking mechanism 25, the side push alignment mechanism 23 pushes the plate to align with the reference surface of the edge sealing device 30, and the pressure wheel mechanism 22 will respond at the same time, pressing the plate down through the roller pressure structure, thereby stabilizing the plate, avoiding the plate from jumping, ensuring the plate to move forward smoothly, and making the plate accurately aligned with the reference surface of the edge sealing device 30, which is conducive to reducing edge sealing defects. The plate is pressed down by the pressure roller 2208, reducing the friction between the pressure roller 2208 and the plate, which is conducive to improving the smoothness of the plate movement.

[0037] As a preferred embodiment, the pressure wheel mechanism 22 also includes a pressure wheel support plate 2201, and a plurality of pressure wheel swing plates 2202 are rotatably connected to the pressure wheel support plate 2201. The plurality of pressure wheel swing plates 2202 are sequentially distributed on one side of the pressure wheel support plate 2201, and a plurality of rocker cylinders 2203 are arranged on the other side of the pressure wheel support plate 2201. The plurality of rocker cylinders 2203 are arranged in a one-to-one correspondence with the plurality of pressure wheel swing plates 2202. The driving end of the rocker cylinder 2203 is connected to the pressure wheel swing plate 2202, and a group of roller pressing structures are arranged on each of the pressure wheel swing plates 2202.

[0038] In this embodiment, since the pressure roller swing plate 2202 is connected to the swing rod cylinder 2203, the swing rod cylinder 2203 can provide a pulling force to pull the pressure roller swing plate 2202, so that the pressure roller swing plate 2202 will not swing due to the push of the side push alignment mechanism 23, and the pulling force of the pressure roller swing plate 2202 can also make the plate close to the reference surface of the edge sealing device 30 for transportation, thereby ensuring that the pressing roller 2208 can stably press the plate. Preferably, a swing rod seat is provided on the pressure roller support plate 2201, and the swing rod seat is rotatably provided with a swing rod shaft, and the pressure roller swing plate 2202 is connected to the swing rod shaft.

[0039] Specifically, the roller pressing structure includes a pressing wheel cylinder 2204, a pressing wheel fixing strip 2205 and a pressing wheel mounting seat 2206. The pressing wheel cylinder 2204 is connected to the pressing wheel swing plate 2202, the driving end of the pressing wheel cylinder 2204 is connected to the pressing wheel fixing strip 2205, the pressing wheel mounting seat 2206 and the pressing wheel fixing strip 2205 are connected by an elastic member, and the pressing roller 2208 is mounted on the pressing wheel mounting seat 2206.

[0040] In this embodiment, the pressure roller cylinder 2204 drives the pressure roller mounting seat 2206 to perform lifting motion, and then the pressure roller 2208 presses down the plate or detaches from the plate, and the pressure roller cylinder 2204 controls the lifting and lowering of the pressure roller 2208, and the control accuracy is good. The pressure roller mounting seat 2206 and the pressure roller fixing bar 2205 are connected by an elastic member, wherein the elastic member is preferably a spring 2207 column, so as to ensure that the pressure roller 2208 flexibly presses down the plate. In addition, each group of the roller pressure delivery structure in this embodiment is driven by a pressure roller cylinder 2204, so that each group of roller pressure delivery structures can operate independently, so that the plate can be pressed down in sections, so that when the plate spacing is satisfied, the auxiliary conveying device 20 can convey multiple plates. As a preferred embodiment, it also includes a pressure wheel bracket, on which a pressure wheel slider is provided, and the pressure wheel slider is connected to a pressure wheel lifting drive assembly, and the other side of the pressure wheel support plate 2201 is provided with a pressure wheel guide rail that slides with the pressure wheel slider, and the pressure wheel lifting drive assembly drives the pressure wheel slider to move up and down along the pressure wheel guide rail.

[0041] In this embodiment, the pressure wheel slider is driven to move up and down by the pressure wheel lifting drive assembly, and then the pressure wheel support plate 2201 is driven to move up and down, so that multiple groups of roller pressing structures are raised or lowered at the same time, so that it can adapt to the pressing requirements of plates of different thicknesses, and the flexibility is strong. As a preferred embodiment, the push handle mechanism 24 includes a push handle assembly 241 and a push handle driving assembly 242 that drives the push handle assembly 241 to move back and forth, the push handle assembly 241 includes a push handle fixing seat 2410 connected to the push handle driving assembly 242 and a push handle cylinder 2411 arranged on the push handle fixing seat 2410, a push handle swing arm 2413 is rotatably connected to the push handle fixing seat 2410, one end of the push handle swing arm 2413 is provided with a push handle stopper 2412, and the push handle swing arm 2413 is connected to the push handle cylinder 2411 to drive the push handle swing arm 2413 to swing through the push handle cylinder 2411.

When the push handle cylinder 2411 is started, the push handle swing arm 2413 is driven to rotate around the push handle connecting shaft 2414 to drive the push handle stopper 2412 to swing up and down, thereby pushing the plate through the push handle stopper 2412. Preferably, the push handle stopper 2412 has an L-shaped structure, and the plate is positioned by the L-shaped structure, so as to stably push the plate. The pushing handle assembly 241 is driven to move by the pushing handle driving assembly 242. Since there will be a certain delay time after the pushing handle mechanism 24 responds to the signal of the second sensor 27, the speed at which the pushing handle driving assembly 242 drives the pushing handle assembly 241 must be greater than the conveying speed of the conveying mechanism 21 to ensure that the pushing handle assembly 241 can catch up with the plate; it can be understood that when the first sensor 26 detects the passage of the plate, the pushing handle assembly 241 is located below the conveying mechanism 21 so that the plate can be conveyed on the conveying mechanism 21, and then the pushing handle swing arm 2413 is driven to swing by the pushing handle cylinder 2411, and then the pushing handle stopper 2412 is extended out from above the conveying mechanism 21 to cooperate with the blocking mechanism 25 to clamp the plate.

[0043] As a preferred embodiment, the blocking mechanism 25 includes a blocking component 251 and a blocking driving component 252 that drives the blocking component 251 to reciprocate, the blocking component 251 includes a blocking slide plate 2510 connected to the blocking driving component 252, a blocking fixed seat 2512 slidingly connected to the blocking slide plate 2510, and a blocking cylinder 2513 arranged on the blocking fixed seat 2512, a blocking swing arm 2515 is rotatably mounted on the blocking fixed seat 2512, the driving end of the blocking cylinder 2513 is connected to the middle part of the blocking swing arm 2515, and the other end of the blocking swing arm 2515 is provided with a blocking wheel 2516, and the blocking cylinder 2513 is used to drive the blocking swing arm 2515 to swing so as to cooperate with the push hand stopper 2412 to clamp the plate through the blocking wheel 2516.

[0044] In this embodiment, a blocking connecting shaft 2514 is provided on the blocking fixed seat 2512, and one end of the blocking swing arm 2515 is rotatably connected to the blocking connecting shaft 2514. The blocking cylinder 2513 drives the blocking swing arm 2515 to rotate around the blocking connecting shaft 2514, so that the other end of the blocking swing arm 2515 swings upward, and then the back wheel 2516 extends out above the conveying mechanism 21, so that the back wheel 2516 cooperates with the push hand stopper 2412 to clamp the plate.

[0045] Specifically, the blocking mechanism 25 further includes a buffer cylinder 2511 , a cylinder body of the buffer cylinder 2511 is fixed on the blocking sliding seat plate 2510 , and a piston portion of the buffer cylinder 2511 is connected to the blocking fixed seat 2512 .

[0046] In this embodiment, the blocking fixing seat 2512 is connected to the buffer cylinder 2511. When the plate contacts the wheel 2516, a thrust is given to the blocking fixing seat 2512, and the blocking fixing seat 2512 will slide, and then compress the buffer cylinder 2511. When the compression amount of the buffer cylinder 2511 reaches a preset value, the buffer cylinder 2511 sends a signal to the control system, indicating that the blocking mechanism 25 and the pusher mechanism 24 have clamped the plate. It can be understood that if the compression amount of the buffer cylinder 2511 exceeds the preset value, it indicates that the blocking mechanism 25 and the pusher mechanism 24 clamp the plate too tightly, and the control system will generate an alarm signal.

[0047] As a preferred embodiment, the push handle driving assembly 242 includes a transmission motor, a transmission synchronous belt and a transmission wheel assembly. The transmission motor drives the transmission synchronous belt to operate through the transmission wheel assembly, and the push handle fixing seat 2410 is in sliding connection with the transmission synchronous belt.

[0048] In this embodiment, the transmission motor drives the transmission synchronous belt through the transmission wheel assembly, and then drives the push handle fixing seat 2410 to move along the conveying direction of the transmission synchronous belt, thereby pushing the plate through the push handle stopper 2412. Preferably, the transmission motor preferably adopts a 3kW servo motor, and is matched with a transmission wheel assembly to achieve a moving speed of up to 230m / min, which greatly reduces the distance between the plates and improves the feeding efficiency.

[0049] Preferably, there are multiple push handle assemblies 241, and the multiple push handle assemblies 241 are installed on a push handle sliding seat plate 243, and the push handle sliding seat plate 243 is slidably connected with the transmission synchronous belt. By setting multiple push handle assemblies 241, it is possible to clamp longer panels, meet the clamping requirements of panels of different sizes, and have strong versatility.

[0050] In addition, the blocking drive assembly 252 adopts the same structure as the push handle drive assembly 242, and the principle is the same as the push handle drive assembly 242, which will not be described in detail here.
