Description

Technical Field

[0001] The utility model relates to the field of edge banding equipment, in particular to a positioning device and an edge banding machine. Background Art

[0002] When using an edge banding machine to edge band a single panel, the length of the edge banding tape needs to be greater than the length of the panel to ensure the edge banding quality. Generally, the edge banding tape needs to be 50 mm longer than the panel. For narrow panels (such as 50 mm long), the loss of the edge banding tape is particularly obvious. In terms of efficiency, the interval between the front and rear panels needs to be greater than 500 mm. When making narrow panels, the accumulated interval is large and the efficiency is low. If the panel splicing method is adopted, the consumption of the edge banding tape can be reduced and the feeding times can be reduced, thereby reducing the loss of the edge banding tape. The conventional operation is that multiple panels are closely arranged together and enter the edge banding machine together, and the edge banding tape is attached to at least two panels at the same time, which has strict requirements for the gap between the two panels. For example, if the two panels enter the edge banding machine independently, due to the different feeding speeds, it is difficult to control the gap between the two panels. If the gap is too large, it will cause waste of the edge banding tape. If the gap is too small, it will be difficult to cut the edge banding tape subsequently to separate the two panels.

[0021] As can be seen from the above description of the present invention and its preferred embodiments, compared with the prior art, the technical solutions and their preferred embodiments of the present invention have the following beneficial effects due to the following technical means:

[0022] 1. In Solution One and its preferred embodiments, a positioning device is adapted to determine the gap between two adjacent plates in the X-axis direction, including a support table and a positioning mechanism.

[0023] The support table is provided with a receiving surface, and the receiving surface is adapted to receive the plate.

[0024] The positioning mechanism is provided with a positioning part, and the positioning part is adapted to move in the Z-axis direction and the X-axis direction. The positioning part is adapted to protrude upward from the receiving surface along the Z-axis at the feeding starting point and is adapted to be clamped by the adjacent plate at the feeding starting point to determine the width of the gap. The positioning part is also adapted to be pushed by the subsequent plate and move along the X-axis direction from the feeding starting point to reach the feeding end point. Thus, during the movement towards the feeding end point, the subsequent plate, the positioning part, and the previous plate move together to keep the gap as constant as possible. By controlling the gap, the waste caused by attaching the edge banding tape to the plate later can be reduced, and it is also convenient to separate the adjacent plates later. The positioning part is also adapted to move downward along the Z-axis at the feeding end point to be lower than the receiving surface, so that it can move along the X-axis to reset to the feeding starting point without being blocked by the plate, for the gap control of the next group of plates.

[0025] 2. In Solution Two and its preferred embodiments, the number of positioning mechanisms is at least two, and when one positioning mechanism is at the feeding end point, at least one positioning mechanism is at the feeding starting point. By alternately using each positioning mechanism, the efficiency can be improved compared with only one positioning mechanism. This process can be achieved through a control member.

[0026] 3. In Solution Three and its preferred embodiments, the synchronous belt is installed on the support table, and the number of positioning mechanisms is two. The two positioning mechanisms are respectively installed on two opposite belts of the synchronous belt, so that when one positioning mechanism is at the feeding starting point, the other positioning mechanism is driven by the synchronous belt to be at the feeding end point. Compared with only one positioning mechanism, the efficiency can be improved. And by using the synchronous belt to drive the movement of the two positioning mechanisms, the movement distance is controllable and accurate, and it is a physical drive for the positioning part to move along the X-axis to reset to the feeding starting point, which is more cost-saving.

[0027] 4. In Solution 4 and its preferred embodiments, the positioning mechanism includes a travel switch. The travel switch is adapted to make the positioning part protrude upward along the Z-axis when the positioning part is at the feeding starting point, and make the positioning part move downward along the Z-axis when the positioning part is at the feeding ending point. Through the travel switch, automatic control of the movement of the positioning part along the Z-axis direction is achieved, which is simple and convenient.

[0028] 5. In Solution 5 and its preferred embodiments, an edge banding machine includes a conveying mechanism, an edge banding mechanism, a trimming mechanism, a cutting mechanism, and the above-mentioned positioning device. The conveying mechanism is adapted to convey the board at the feeding ending point so that subsequent workstations can perform processing. The edge banding mechanism is adapted to attach an edge band to two adjacent boards. The edge band passes over the gap from one board and is connected to the other board, enabling the two boards to be edge banded together, saving costs. The trimming mechanism is adapted to trim the edge band on adjacent boards to remove the excess edge band. The cutting mechanism is adapted to cut the edge band on adjacent boards to separate the two boards and complete the edge banding. This edge banding machine has the beneficial effects brought by the above-mentioned positioning mechanism.

[0029] 6. In Solution 6 and its preferred embodiments, since the widths of the two boards may not be the same during edge banding, and the distance between the two sets of gaps is not constant according to different feeding speeds, the position of the gap is uncertain, and it may not be possible to perform cutting at the same rhythm.

[0030] In this embodiment, an image is taken by a camera to obtain the position of the gap; the control part is adapted to control the cutting mechanism to cut the edge band when the position of the gap corresponds to the position of the cutting mechanism, so as to make the cutting stable and accurate.

[0031] 7. In Solution 7 and its preferred embodiments, the cutting mechanism physically cuts the edge band, so the cutting mechanism needs to move accordingly. The transfer part is adapted to drive the cutting mechanism to transfer along the X-axis direction and the Y-axis direction so that the cutting mechanism cuts the edge band, thereby achieving cutting, which is simple and convenient. Since the conveying mechanism of the edge banding machine usually cannot stop during operation, otherwise it will affect the attachment of the edge band and result in unqualified edge banding of the product, the cutting mechanism also needs to move along the X-axis direction.

[0032] 8. In Solution 8 and its preferred embodiments, the transfer part includes a first moving part and a second moving part. The first moving part is adapted to move along the X-axis direction, and the second moving part is adapted to move along the Y-axis direction. The first moving part and the second moving part are assembled with each other, and the final output ends of both are connected to the cutting mechanism, thereby realizing the movement of the cutting mechanism.

[0033] The control part controls the speed of the first moving part moving along the X-axis direction to be consistent with the transfer speed of the conveying mechanism, so as to ensure synchronization between the two and prevent collision.

[0034] 9. In Solution Nine and its preferred embodiments, the sensor is adapted to emit a detection signal when it senses the front end of the previous plate member, and the control member is adapted to control the camera to take an image to obtain the position of the gap when it acquires the detection signal, so as to confirm the time of obtaining the position of the gap, which has a lower cost compared to real-time shooting.

[0035] 10. In Solution Ten and its preferred embodiments, the pre-milling mechanism is located on the front side of the edge-sealing mechanism and is used to cut the surface layer of the plate member, so as to facilitate the attachment of the edge-sealing strip.

[0036] 11. In Solution Eleven and its preferred embodiments, a polishing mechanism is further included, which is located behind the cutting mechanism and is used to polish the surface of the plate member to achieve surface cleaning. Description of the Drawings

[0055] Refer to Figures 1 - 8, An edge banding machine, comprising a positioning device, a conveying mechanism 4, and a pre-milling mechanism 5, an edge banding mechanism 6, a trimming mechanism 7, a cutting mechanism 8, and a polishing mechanism 20 arranged in sequence along the X-axis.

[0056] The positioning device includes a support table 1, a positioning mechanism 3, and a synchronous belt 2.

[0057] Reference Figures 5 - 7 , The support table 1 is provided with a receiving surface 11 and through holes 12. The receiving surface 11 is adapted to receive the plate member 30; the number of through holes 12 is two, and the two through holes 12 are arranged at intervals in the Y-axis direction, penetrate the receiving surface 11 in the Z-axis direction, and the through holes 12 extend in the X-axis direction. The support table 1 is also provided with two guide rails 13 extending in the X-axis direction. Among them, the X-axis direction is Figure 2 the left-right direction in

[0058] Reference Figure 1 , The positioning mechanism 3 is located on the left side of the conveying mechanism 4. The positioning mechanism 3 can determine that there is a gap in the X-axis direction between two adjacent plate members 30 to prevent waste caused by too large a gap when attaching the edge band 40 to the adjacent plate members 30 subsequently. The positioning mechanism 3 can be a lifting motor, and the output end of the lifting motor forms a positioning portion 31. The positioning mechanism 3 can also be a cylinder to achieve corresponding actions.

[0059] Reference Figure 5 , The positioning portion 31 is adapted to move in the Z-axis direction and the X-axis direction. The positioning portion 31 is adapted to protrude upward from the receiving surface 11 in the Z-axis direction at the feeding starting point and be clamped by the adjacent plate member 30 at the feeding starting point to determine the width of the gap; the positioning portion 31 is also adapted to be pushed by the latter plate member 30 (the plate member 30 farther from the conveying mechanism 4), and move in the X-axis direction from the feeding starting point to reach the feeding end point, so that the plate member 30 is driven by the conveying mechanism 4 to the rear working station; the positioning portion 31 is also adapted to move downward in the Z-axis direction to be lower than the receiving surface 11 at the feeding end point and move back to the feeding starting point in the X-axis direction. The advancement of the latter plate member 30 can be achieved manually or mechanically.

[0060] The number of positioning mechanisms 3 is at least two, and when one positioning mechanism 3 reaches the feeding end point, at least one positioning mechanism 3 is located at the feeding starting point. Preferably in this embodiment, the synchronous belt 2 is installed on the lower surface of the support table 1 and is adapted to drive along the X-axis direction. The number of positioning mechanisms 3 is two, and the two positioning mechanisms 3 are respectively arranged corresponding to the through holes 12, so that the positioning parts 31 can extend out or dive into the through holes 12. The two positioning mechanisms 3 are respectively slidably connected to the two guide rails 13 to achieve the guiding function when the positioning mechanisms 3 slide. The two positioning mechanisms 3 are respectively installed on two opposite belts of the synchronous belt 2, so that when one positioning mechanism 3 is at the feeding starting point, the other positioning mechanism 3 is driven by the synchronous belt 2 and is located at the feeding end point. In this embodiment, the telescoping of the positioning part 31 along the Z-axis direction can be controlled by a travel switch. The travel switch is adapted to make the positioning part 31 protrude upward along the Z-axis when the positioning part 31 is at the feeding starting point, and make the positioning part 31 move downward along the Z-axis when the positioning part 31 is at the feeding end point. There can be two such travel switches to trigger respectively at the feeding starting point and the feeding end point, or one can be set. This travel switch is a two-way travel switch, and this travel switch can be triggered mechanically, by a control signal, by being powered on, by a sensor, etc., which is not limited herein.

[0061] Reference Figure 1 , The conveying mechanism 4 is adapted to convey the plate member 30 located at the feeding end point. In this embodiment, two plate members 30 are conveyed as a group. There is a gap in the X-axis direction between two adjacent plate members 30.

[0062] Reference Figure 1 , The pre-milling mechanism 5 is used to cut the surface layer of the plate member 30 to facilitate the edge banding mechanism 6 to attach the edge band 40 to the plate 30.

[0063] Reference Figure 1 , The edge banding mechanism 6 is adapted to attach the edge band 40 to two adjacent plate members 30, and the edge band 40 is connected to another plate member 30 after crossing the gap from one plate member 30.

[0064] Reference Figure 1 , The edge trimming mechanism 7 is adapted to trim the edge band 40 on the adjacent plate members 30. The edge trimming mechanism 7 includes a front edge trimming member 71, a rear edge trimming member 72, an upper edge trimming member 73 and a lower edge trimming member 74, which respectively cut off the edge band 40 that exceeds the ends of the two plates 30.

[0065] Reference Figure 1 , The cutting mechanism 8 is adapted to cut the edge band 40 on the adjacent plate members 30, so that the two plate members 30 are no longer connected to each other through the edge band 40, making them independent and completing the edge banding. The cutting mechanism 8 physically cuts the edge band 40. The cutting mechanism 8 includes a rotating motor and a saw blade, and the rotating motor is adapted to drive the saw blade to rotate. In other embodiments, other methods can also be used, such as laser cutting, etc. The physical cutting method has a lower cost.

[0066] Reference Figure 8 , the camera 9 is adapted to capture an image to obtain the position of the gap. In this embodiment, the position of the gap can be determined by the distance from the foremost end of the previous plate member 30 (the plate member 30 near the right end) to the middle of the gap.

[0067] Reference Figure 8 , the transfer member 10 is adapted to drive the cutting mechanism 8 to transfer along the X-axis direction and the Y-axis direction so that the cutting mechanism 8 cuts the edge band 40; the transfer member 10 includes a first moving member 101 and a second moving member 102. The first moving member 101 is adapted to move along the X-axis direction, and the second moving member 102 is adapted to move along the Y-axis direction. The first moving member 101 and the second moving member 102 are assembled with each other, and the final output ends of the two are connected to the cutting mechanism 8, so as to drive the cutting mechanism 8 to move along the X-axis direction and the Y-axis direction. It can be that the second transfer member 102 is installed on the first transfer member 101, and the output end of the second transfer member 102 is connected to the cutting mechanism 8, or the first transfer member 101 is installed on the second transfer member 102, and the output end of the first transfer member 101 is connected to the cutting mechanism 8.

[0068] The sensor (not shown in the figure) is adapted to emit a detection signal when sensing the front end of the previous plate member 30, and the control member is adapted to control the camera 9 to capture an image to obtain the position of the gap when obtaining the detection signal. The control member is adapted to control the transfer member 10 to drive the cutting mechanism 8 to transfer to cut the edge band 40 when the position of the gap corresponds to the position of the cutting mechanism 8. In the above description, the position of the gap can be determined by the distance from the foremost end of the previous plate member 30 to the middle of the gap. Since the saw blade of the cutting mechanism 8 has a thickness, the edge band 40 on both sides of the middle of the gap can be cut off, so as to cut off the edge band 40 at the gap. The control member controls the speed of the first moving member 101 moving along the X-axis direction to be consistent with the transfer speed of the conveying mechanism 4. During the cutting process, the first moving member 101 and the second moving member 102 cooperate together so that the cutting mechanism 8 moves along the X-axis direction and also moves along the Y-axis direction while moving along the X-axis direction. To determine that the position of the gap corresponds to the position of the cutting mechanism 8, it can be determined according to the distance between the gap and the cutting mechanism 8 and the transfer time of the conveying mechanism 4 (the transfer speed of the conveying mechanism 4 is constant).

[0069] Reference Figure 1 , the polishing mechanism 20 is located behind the cutting mechanism 8 and is used for polishing the surface of the plate member 30.

[0070] Reference Figure 1 、 Figure 2 and Figure 4 、 Figure 5, during use, a positioning mechanism 3 is located at the starting point of feeding, and its positioning portion 31 protrudes from the receiving surface 11. Another positioning mechanism 3 is located at the ending point of feeding, and its positioning portion 31 is lower than the receiving surface 11. Place two plate members 30 on the receiving surface 11, and clamp the positioning portion 31 at the starting point of feeding between the two plate members 30. After clamping, push the latter plate member 30, so that the latter plate member 30 drives the positioning portion 31 at the starting point of feeding and the former plate member 30 to move together towards the conveying mechanism 4 until reaching the ending point of feeding. The positioning portion 31 moves downward to be below the receiving surface 11, and the two plate members 30 will be conveyed together by the conveying mechanism 4. During this process, the positioning mechanism 3 at the ending point of feeding is driven by the synchronous belt 2 to move towards the starting point of feeding. When reaching the starting point of feeding, the positioning portion 31 extends out of the receiving surface 11.

[0071] When the plate member 30 is conveyed by the conveying mechanism 4, it successively passes through a pre-milling mechanism 5, an edge banding mechanism 6, a cutting mechanism 8, and a polishing mechanism 20. The pre-milling mechanism 5 is used to cut the surface layer of the plate member 30. The edge banding mechanism 6 is adapted to attach an edge band 40 to two adjacent plate members 30. The edge band 40 is connected from one plate member 30 across the gap to the other plate member 30. The edge trimming mechanism 7 is adapted to trim the edge band 40 on the adjacent plate members 30.

[0072] The sensor is adapted to emit a detection signal when sensing the front end of the former plate member 30. The control member is adapted to, when obtaining the detection signal, control the camera 9 to take an image to obtain the position of the gap. When the position of the gap corresponds to the position of the cutting mechanism 8, the control member enables the first moving member 101 and the second moving member 102 to cooperate together, so that while the cutting mechanism 8 moves along the X-axis direction, it also moves along the Y-axis direction to cut the edge band 40 on the adjacent plate members 30 during transportation to make them independent.

[0073] The polishing mechanism 20 is located behind the cutting mechanism 8 and is used to polish the surface of the plate member 30, and the edge banding is completed.

[0074] Compared with the prior art, the present embodiment has the following beneficial effects:

[0075] In an exemplary embodiment, a positioning device is adapted to determine that there is a gap in the X-axis direction between two adjacent plate members 30, and includes a support table 1 and a positioning mechanism 3.

[0076] The support table 1 is provided with a receiving surface 11, and the receiving surface 11 is adapted to receive the plate member 30;

[0077] The positioning mechanism 3 is provided with a positioning part 31. The positioning part 31 is adapted to move along the Z-axis direction and the X-axis direction. The positioning part 31 is adapted to protrude upward from the receiving surface 11 along the Z-axis at the feeding starting point, and is adapted to be clamped by the adjacent plate 30 at the feeding starting point to determine the width of the gap. The positioning part 31 is also adapted to be pushed by the subsequent plate 30 and move along the X-axis direction from the feeding starting point to reach the feeding end point. Thus, during the movement towards the feeding end point, the subsequent plate 30, the positioning part 31, and the previous plate 30 move together to keep the gap as unchanged as possible. By controlling the gap, the waste caused by subsequent attaching of the edge band 40 to the plate 30 can be reduced, and thus it is also convenient to separate the adjacent plates 30 subsequently. The positioning part 31 is also adapted to move downward along the Z-axis at the feeding end point to be lower than the receiving surface 11, so that it can move along the X-axis to reset to the feeding starting point without being blocked by the plate 30, for the gap control of the next group of plates 30.

[0078] In an exemplary embodiment, the number of the positioning mechanisms 3 is at least two. When one positioning mechanism 3 is at the feeding end point, at least one positioning mechanism 3 is at the feeding starting point. By alternately using each positioning mechanism 3, compared with only one positioning mechanism 3, the efficiency can be improved. This process can be achieved through a control member.

[0079] In an exemplary embodiment, the synchronous belt 2 is installed on the support table 1. The number of the positioning mechanisms 3 is two. The two positioning mechanisms 3 are respectively installed on two opposite belts of the synchronous belt 2, so that when one positioning mechanism 3 is at the feeding starting point, the other positioning mechanism 3 is driven by the synchronous belt 2 and is at the feeding end point. Compared with only one positioning mechanism 3, the efficiency can be improved. By driving the movement of the two positioning mechanisms 3 through the synchronous belt 2, the movement distance is controllable and accurate, and it is a physical drive for the positioning part 31 to move along the X-axis to reset to the feeding starting point, which is more cost-saving.

[0080] In an exemplary embodiment, the positioning mechanism 3 includes a travel switch. The travel switch is adapted to make the positioning part 31 protrude upward along the Z-axis when the positioning part 31 is at the feeding starting point, and make the positioning part 31 move downward along the Z-axis when the positioning part 31 is at the feeding end point. Through the travel switch, the automatic control of the movement of the positioning part 31 along the Z-axis direction is realized, which is simple and convenient.

[0081] In an exemplary embodiment, an edge banding machine includes a conveying mechanism 4, an edge banding mechanism 6, a trimming mechanism 7, a cutting mechanism 8, and the above-mentioned positioning mechanism 3. The conveying mechanism 4 is adapted to convey a plate member 30 located at the feeding end, so that subsequent workstations can perform processing. The edge banding mechanism 6 is adapted to attach an edge band 40 to two adjacent plate members 30. The edge band 40 passes over a gap from one plate member 30 and is connected to the other plate member 30, so that the two plate members 30 are edge-banded together, saving costs. The trimming mechanism 7 is adapted to trim the edge band 40 on the adjacent plate members 30 and remove the excess edge band 40. The cutting mechanism 8 is adapted to cut the edge band 40 on the adjacent plate members 30 to separate the two plate members 30 and complete the edge banding. This edge banding machine has the beneficial effects brought by the above-mentioned positioning mechanism 3.

[0082] In an exemplary embodiment, since the widths of the two plate members 30 may be inconsistent during edge banding (such as Figure 9 , Figure 10 ), and according to the different feeding speeds, the distance between the two sets of gaps (taking two plate members 30 as a group) is not constant either. This results in the position of the gap being uncertain and may not be able to be cut at the same rhythm.

[0083] In this embodiment, a camera 9 is used to capture an image to obtain the position of the gap; the control member is adapted to control the cutting mechanism 8 to cut the edge band 40 when the position of the gap corresponds to the position of the cutting mechanism 8, so as to make the cutting stable and accurate.

[0084] In an exemplary embodiment, the cutting mechanism 8 physically cuts the edge band 40. Therefore, the cutting mechanism 8 needs to move accordingly. The transfer member 10 is adapted to drive the cutting mechanism 8 to be transferred along the X-axis direction and the Y-axis direction so that the cutting mechanism 8 cuts the edge band 40, thereby realizing cutting, which is simple and convenient. Since the conveying mechanism 4 of the edge banding machine usually cannot stop during operation, otherwise it will affect the attachment of the edge band 40 and cause the edge banding of the product to be unqualified. Therefore, the cutting mechanism 8 also needs to move along the X-axis direction.

[0085] In an exemplary embodiment, the transfer member 10 includes a first moving member 101 and a second moving member 102. The first moving member 101 is adapted to move along the X-axis direction, and the second moving member 102 is adapted to move along the Y-axis direction. The first moving member 101 and the second moving member 102 are assembled with each other, and the final output ends of both are connected to the cutting mechanism 8, thereby realizing the movement of the cutting mechanism 8.

[0086] The control member controls the speed of the first moving member 101 moving along the X-axis direction to be consistent with the transfer speed of the conveying mechanism 4, so as to ensure synchronization between the two and prevent collision.

[0087] In an exemplary embodiment, the sensor is adapted to emit a detection signal when it senses the front end of the previous panel 30. The control member is adapted to control the camera 9 to capture an image to obtain the position of the gap when it acquires the detection signal, so as to confirm the time of obtaining the position of the gap, which has a lower cost compared with real-time shooting.

[0088] In an exemplary embodiment, a pre-milling mechanism 5 is further included. The pre-milling mechanism 5 is located on the front side of the edge banding mechanism 6 and is used for cutting the surface layer of the panel 30, so as to facilitate the attachment of the edge band 40.

[0089] In an exemplary embodiment, a polishing mechanism 20 is further included. It is located behind the cutting mechanism 8 and is used for polishing the surface of the panel 30 to achieve surface cleaning.
