Description

Technical Field

[0001] The present invention relates to gypsum board processing technology, in particular to an edge band supply mechanism and an edge band device. Background Art

[0002] In the production process of gypsum board, the edges of both sides of the gypsum board need to be edge-sealed. In the edge-sealing process, the edge band is fixed to the side of the gypsum board during the movement of the board. The edge band is in rolls. When a roll of edge band is used up, it needs to be replaced manually in time to ensure the continuous operation of the edge banding process.

[0003] However, since different gypsum boards move at different speeds on the production equipment, the usage time of different edge banding tapes is also different, and human energy is limited, it is impossible to detect in time that the edge banding tapes are used up, which affects the efficiency of the edge banding process. Summary of the invention

[0004] The embodiments of the present application provide an edge banding supply mechanism and an edge banding device to solve the problem that it is not easy to detect that the edge banding has been used up.

[0005] On the one hand, an embodiment of the present application provides an edge band supply mechanism, comprising: a pallet, configured to carry the edge band; a unwinding wheel, arranged on the pallet and capable of rotating around the axis of the pallet, the edge band wrapping around the periphery of the unwinding wheel, and the unwinding wheel being configured to rotate with the movement of the edge band; a detection unit, configured to detect the number of rotations of the unwinding wheel; and an execution unit, configured to issue a first alarm when the number of rotations of the unwinding wheel is greater than or equal to a first preset value.

[0006] In an exemplary embodiment, the detection part includes a moving part and a sensing part, the moving part is arranged on a side surface of the unwinding wheel facing the pallet, and the sensing part is arranged on a side surface of the pallet facing the unwinding wheel; the moving part approaches and moves away from the sensing part as the unwinding wheel rotates, and the sensing part increases the number of rotations of the unwinding wheel by one each time it senses the approach to the moving part.

[0007] In an exemplary embodiment, the sensing member is located within the range of the orthographic projection of the unwinding wheel on the tray; and the moving member can overlap with the sensing member during the movement.

[0008] In an exemplary embodiment, the sensing element is a proximity switch.

[0009] In an exemplary embodiment, a first blind hole is provided on a side surface of the unwinding wheel facing the tray, and the moving member is disposed in the first blind hole.

[0010] In an exemplary embodiment, a rotating shaft is further included, and the rotating shaft passes through the pallet and the unwinding wheel along the axis of the pallet. During the movement of the edge band, the unwinding wheel rotates around the rotating shaft.

[0011] In an exemplary embodiment, the execution unit includes a judgment module and an alarm module, the judgment module is configured to judge the relationship between the number of rotations of the unwinding wheel and the first preset value, and to send a first alarm signal to the alarm module when the number of rotations of the unwinding wheel is greater than or equal to the first preset value; the alarm module is configured to receive the first alarm signal and send the first alarm.

[0012] In an exemplary embodiment, the execution unit is further configured to issue a second alarm when the number of additional rotations of the unwinding wheel within the first time period is less than 1.

[0013] In an exemplary embodiment, the judgment module is also configured to judge whether the newly added number of rotations of the unwinding wheel within the first time period is less than 1, and to send a second alarm signal to the alarm module if it is judged that the newly added number of rotations of the unwinding wheel within the first time period is less than 1; the alarm module is also configured to receive the second alarm signal and send the second alarm.

[0014] On the other hand, an embodiment of the present application further provides an edge banding device, comprising the edge banding supply mechanism as described above.

[0015] The edge band supply mechanism provided in the embodiment of the present application places the edge band on a pallet and surrounds the outer periphery of the unwinding wheel. The movement of the edge band can drive the unwinding wheel to rotate on the pallet, so that the length consumption of the edge band is related to the number of rotations of the unwinding wheel. By using the detection unit to detect the number of rotations of the unwinding wheel, the length consumption of the edge band can be obtained. By presetting a suitable first preset value, the execution unit issues a first alarm when the number of rotations of the unwinding wheel is greater than the first preset value, which can remind the staff to pay attention to the roll of edge band, so that the staff can replace the edge band in time, reduce the dependence on manual labor to find that the edge band is exhausted, and help to ensure the efficiency of the edge banding process.

[0022] Figure 1 Schematic diagram of the structure of an edge sealing device. Figure 1 As shown, the edge banding device of the gypsum board may include: an edge banding supply mechanism 1, a water redirection mechanism 2, a paper folding device 3 and an edge banding pressing wheel 4. Figure 1 As shown, the edge band 10 is arranged on the edge band supply mechanism 1, and the paper folding device 3 and the edge band pressing wheel 4 are arranged on the side of the gypsum board 20. The edge band 10 passes through the redirecting water supply mechanism 2 along the arrow direction on itself and reaches the side of the gypsum board 20. The redirecting water supply mechanism 2 can supply water to the edge band 10 to make the edge band 10 moist. The moistened edge band 10 can be more easily attached to the side of the gypsum board 20 later. The redirecting water supply mechanism 2 can also adjust the direction of the edge band 10. After passing through the redirecting water supply mechanism 2, the edge band 10 can enter between the paper folding device 3 and the side of the gypsum board 20. The paper folding device 3 adjusts the shape of the edge band 10 to fit the side and upper and lower surfaces of the gypsum board 20, and the edge band pressing wheel 4 can press the edge band 10 against the side of the gypsum board 20. Figure 1 A side edge of a gypsum board 20 is shown in the figure. The gypsum board 20 moves along the direction of arrow A on the production equipment (not shown in the figure). The movement of the gypsum board 20 drives the edge banding 10 provided on the edge banding supply mechanism 1 to move, so that the edge banding 10 is attached to the side edge of the gypsum board 20, thereby completing the edge banding.

[0023] In an exemplary embodiment, the redirecting water supply mechanism 2 may include a sponge wheel 21 and an edge banding guide wheel 22. The sponge wheel 21 can supply water to the edge banding belt 10 to keep the edge banding belt 10 at an appropriate wetness. The edge banding guide wheel 22 can cooperate with the sponge wheel 21 to control the direction of the edge banding belt 10.

[0024] like Figure 1As shown in the figure, the edge banding material is in roll form. In the edge banding process, it is usually manually detected whether the edge banding is used up and replaced with a new one in time. However, due to the different movement speeds of different gypsum boards on the production equipment, the use time of different edge bandings is also different. However, due to the limited manual energy, it is not possible to detect the edge banding being used up in time, and the edge banding process is not easy to run continuously, which affects the efficiency of the edge banding process.

[0025] The embodiment of the present application provides an edge band supply mechanism, comprising: A pallet configured to carry an edge band; An unwinding wheel is arranged on the pallet and can rotate around the axis of the pallet, the edge band surrounds the outer periphery of the unwinding wheel, and the unwinding wheel is arranged to rotate with the movement of the edge band; A detection unit, configured to detect the number of rotations of the unwinding wheel; The execution unit is configured to issue a first alarm when the number of rotations of the unwinding wheel is greater than or equal to a first preset value.

[0026] The edge banding supply mechanism provided in the embodiment of the present application places the edge banding on a pallet and surrounds it around the periphery of a unwinding wheel. The movement of the edge banding can drive the unwinding wheel to rotate on the pallet, so that the length consumption of the edge banding is related to the number of rotations of the unwinding wheel. By utilizing the detection unit to detect the number of rotations of the unwinding wheel, the length consumption of the edge banding can be obtained. By pre-setting a suitable first preset value, the execution unit will issue a first alarm when the number of rotations of the unwinding wheel is greater than the first preset value, which can remind the staff to pay attention to the roll of edge banding, making it convenient for the staff to replace the edge banding in time, reducing dependence on manual labor, and helping to ensure the efficiency of the edge banding process.

[0027] Figure 2 It is a schematic structural diagram of the edge band supply mechanism in the exemplary embodiment of the present application. Figure 3 In an exemplary embodiment Figure 2 Top view of the tray. Figure 4 In an exemplary embodiment Figure 2 Bottom view of the unwinding wheel.

[0028] Combination Figures 2 to 4As shown, the edge band supply mechanism provided in the embodiment of the present application includes a tray 101, an unwinding wheel 102, a detection unit, and an execution unit. The tray 101 can carry the edge band 10, and the unwinding wheel 102 can be arranged on the tray 101. In the direction perpendicular to the tray 101, the tray 101 can have an axis O, and the edge band 100 surrounds the outer periphery of the unwinding wheel 102. The unwinding wheel 102 can rotate around the axis O of the tray 101. During the movement of the edge band 10, the unwinding wheel 102 is driven to rotate along the axis O. In an exemplary embodiment, the axis O can be a straight line passing through the center of the geometric shape of the tray 101 and perpendicular to the tray 101, and the geometric shape of the tray 101 can be the geometric shape of the surface of one side of the tray 101 facing the unwinding wheel 102. For example, the geometric shape of the tray 101 can be circular, and the axis O can be a straight line passing through the center of the tray 101 and perpendicular to the tray 101. The geometric shape of the tray 101 can also be a triangle, an ellipse, a quadrilateral, a polygon, an irregular shape, etc. The geometric shape of the tray 101 can be set as needed, and the present application does not impose any restrictions on this.

[0029] In an exemplary embodiment, the edge band supply mechanism may further include a rotating shaft 110, which passes through the pallet 101 and the unwinding wheel 102 along the axis O. During the movement of the edge band 10, the unwinding wheel 102 may rotate around the rotating shaft 110, the rotating shaft 110 may rotate together with the unwinding wheel 102, or the rotating shaft 110 itself may not rotate. The present application does not impose any restrictions on this.

[0030] Figure 3 The dotted circle in FIG. 1 represents the contact surface shape between the unwinding wheel 102 and the tray 101. Figure 3 and Figure 4 As shown, the detection unit may include a sensing member 103 disposed on a side surface of the tray 101 facing the unwinding wheel 102, and a moving member 104 disposed on a side surface of the unwinding wheel 102 facing the tray 101. The moving member 104 approaches and moves away from the sensing member 103 as the unwinding wheel 102 rotates. The sensing member 103 counts the number of rotations of the unwinding wheel 102 by one each time it senses that the moving member 104 is approaching each other. The sensing member 103 may be located within the range of the positive projection of the unwinding wheel 102 on the tray 101. The moving member 104 may overlap with the sensing member 103 during the movement. The moving member 104 and the sensing member 103 may overlap with each other in the initial state, or the moving member 104 and the sensing member 103 may not overlap with each other in the initial state. The present application does not limit this.

[0031] In an exemplary embodiment, a first blind hole may be provided on the surface of the unwinding wheel 102 facing the tray 101, and the moving part 104 may be disposed in the first blind hole. The material of the unwinding wheel 102 may be a non-metallic material, such as a ceramic material, etc., and the moving part 104 may be a metal material, such as iron or other metals and alloy materials, etc. The materials of the unwinding wheel 102 and the moving part 104 may be set as required, and the present application does not limit this. For example, the sensing part 103 may be set in the original opening of the tray 101, and the moving part 104 may be an iron sheet fixed in the first blind hole. This arrangement may reduce the cost of modifying the edge band supply mechanism.

[0032] In an exemplary embodiment, the sensing element 103 may be a proximity switch, and the edge-triggered principle may be used for counting between the sensing element 103 and the moving element 104. The present application does not limit the type of the proximity switch, the counting principle between the sensing element 103 and the moving element 104, etc.

[0033] In an exemplary embodiment, the execution unit (not shown) may include a judgment module and an alarm module. The judgment module can obtain the count of the sensor 103 and send an alarm signal to the alarm module. For example, the sensor 103, the judgment module and the alarm module may be electrically connected. The judgment module may be a computer or a programmable logic controller (PLC). After obtaining the count of the sensor 103, the judgment module may determine the relationship between the number of rotations of the unwinding wheel 102 and the first preset value. When it is determined that the number of rotations of the unwinding wheel 102 is greater than or equal to the preset first preset value, the first alarm signal is sent to the alarm module. After receiving the first alarm signal, the alarm module sends a first alarm.

[0034] In an exemplary embodiment, the first preset value is related to parameters such as the length, thickness (number of turns) of the edge band 10, and the movement speed of the gypsum board. Each time the gypsum board moves forward, the edge band 10 is driven to move a certain distance, and the unwinding wheel 102 rotates a corresponding number of times. As the edge band 10 is used, the diameter of the edge band 10 around the unwinding wheel 102 decreases, and the number of turns of the unwinding wheel 102 will increase when the edge band 10 moves the same distance. In an exemplary embodiment, these parameters can be counted in advance, and a model can be established for the relationship between the number of turns of the unwinding wheel 102 and the remaining length of the edge band 10. The subsequent judgment module can directly use the model to judge the remaining length of the edge band 10. In the case where the length of each batch of edge bands 10 is different, the length parameter of the edge band 10 can be re-entered after the edge band 10 is replaced. The model can automatically judge the remaining length of the current roll of edge band 10 according to the number of turns of the unwinding wheel 102, and issue an alarm in time. Alternatively, when the length of each roll of edge banding 10 is the same, the total number of rotations of the unwinding wheel 102 when a roll of edge banding 10 is completely used up can be calculated in advance, and the first preset value can be less than or equal to the total number of rotations of the unwinding wheel 102. After each replacement of a new edge banding 10, re-counting can be triggered, or counting can continue based on the original count, which is not limited in the present application.

[0035] For example, when the total number of rotations of the unwinding wheel 102 is 12 when a roll of edge banding 10 is completely used up, the first preset value may be 10. After the alarm module issues the first alarm, the staff can have sufficient time to prepare a new edge banding 10 for timely replacement. The relationship between the first preset value and the total number of rotations of the unwinding wheel 102 may be set as needed, and the present application does not limit this.

[0036] The inventors of the present application also discovered that due to reasons such as moisture in the edge banding, the edge banding is prone to breakage during the gypsum board edge banding process. If it is not discovered and processed in time by humans, the board cannot be edged. Subsequently, these unedge-banded boards need to be re-selected and reprocessed, which greatly wastes manpower and material resources and reduces production efficiency.

[0037] In an exemplary embodiment, the judgment module is also configured to judge whether the newly added number of rotations of the unwinding wheel 102 within the first time period is less than 1, and if it is judged that the newly added number of rotations of the unwinding wheel 102 within the first time period is less than 1, a second alarm signal is sent to the alarm module, and the alarm module sends a second alarm after receiving the second alarm signal.

[0038] When the edge banding 10 is broken, the edge banding 10 will not move with the movement of the gypsum board, and the unwinding wheel 102 will not rotate. Therefore, the first time period can be pre-set in combination with the actual production situation, and when the number of additional rotations of the unwinding wheel 102 in the first time period is less than 1, a second alarm is issued to indicate that the edge banding 10 is broken. The first time period can be related to parameters such as the movement speed of the gypsum board and the movement interval between adjacent gypsum boards, and the present application does not limit this.

[0039] In an exemplary embodiment, the judgment module may count the first time period and determine whether the belt is broken in combination with the number of rotations of the unwinding wheel detected by the detection unit, and the present application does not impose any limitation on this.

[0040] In an exemplary embodiment, the first alarm and the second alarm may be sound and light alarms, which may be the emission of an alarm prompt sound and / or the display of an alarm prompt message on a display screen, the alarm prompt sound may be music or a human voice, and the content of the human voice may be “the edge band of the xx pallet is about to run out”, “the edge band of the xx pallet is broken”, etc. The first alarm and the second alarm may also include sending a text message to a technician, making a phone call, etc., which is not limited in this application.
