Description

Technical Field

[0001] The invention relates to the technical field of plate processing, and in particular to a plate alignment mechanism and a panel saw device. Background Art

[0002] When sawing plates, the sawing accuracy is reduced due to problems such as poor uniformity and position offset of the stacked plates. Therefore, before sawing, a plate alignment mechanism is required to make the plates reach a flush state in the conveying direction to improve the sawing accuracy.

[0003] In the prior art, the plate alignment mechanism includes a backing plate and a driving unit for driving the backing plate to move, wherein some driving units such as a telescopic cylinder can drive the backing plate to rise and fall, however, after completing the plate alignment process, the backing plate will move downward and scratch the side of the plate, resulting in damage to the appearance of the plate, and in addition, when the plate is large in size and weight, when the plate contacts the backing plate, the plate will exert a large collision effect on the backing plate. At this time, since the force exerted by the driving unit on the backing plate is perpendicular to the direction of the collision effect, the driving unit can be easily damaged due to the strong collision effect, such as bending and deformation of the movable rod of the telescopic cylinder.

[0004] In addition, there are some driving units such as telescopic cylinders that can drive the backrest to flip up and down around its own rotation axis, which can prevent the backrest from damaging the plate. However, since the force applied by the driving unit to the backrest is not collinear with the direction of the collision, the driving unit needs to apply a force greater than the collision to prevent the backrest from flipping downward due to the collision and affecting the flush effect of the plate. This will lead to increased performance requirements for the driving unit and increased costs. Moreover, the driving unit is prone to failures due to strong collisions, such as bending and deformation of the active rod of the telescopic cylinder, which increases maintenance costs. Summary of the invention

[0005] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention provides a board alignment mechanism and a panel saw device, which can achieve the board alignment function while avoiding scratches on the surface of the board, and is reliable, durable, not easy to damage, and low in cost.

[0006] The first aspect of the present invention provides a plate alignment mechanism, which has a first direction, a second direction and an up-down direction that are perpendicular to each other, and includes: An alignment member, wherein one side of the alignment member along the second direction is provided with an alignment surface extending in the up-down direction, and at least one side of the alignment member along the first direction is provided with a first guide portion and a second guide portion; A side plate, wherein a first guide groove and a second guide groove are arranged at intervals along a second direction on a side surface thereof along the first direction, wherein the first guide groove extends along the second direction and is adaptively connected to the first guide portion, and the second guide groove extends from top to bottom along an arc trajectory and is adaptively connected to the second guide portion, and the center position of the arc trajectory is located on a side of the second guide groove along the second direction close to the alignment surface; A linear drive member, whose movable end is hinged to the alignment member, and the hinge axis of the movable end is colinear with the central axis of the first guide portion along the first direction; when the movable end moves along the second direction toward away from the alignment surface, the first guide portion can move along the extension direction of the first guide groove, and the second guide portion can move along the second direction on the upper surface of the side plate, and then, the alignment member rotates around the central axis of the first guide portion so that the second guide portion can enter the second guide groove and move downward along the extension direction of the second guide groove, and the alignment surface is flipped from a vertical state to an upward state.

[0007] The plate alignment mechanism according to the first aspect of the embodiment of the present invention has at least the following beneficial effects: when the alignment member is in working condition, the alignment surface on the alignment member extends in the up and down directions, and can align the plate. During this process, since the collision force exerted by the plate on the alignment surface and the force exerted by the linear drive member on the alignment member are colinearly arranged in the second direction, the force exerted by the linear drive member on the alignment member is equal to the collision force and can relatively offset each other. Therefore, the performance requirements and costs of the linear drive member can be reduced, and the linear drive member can be prevented from easily failing due to the large collision force, thereby extending the service life of the plate alignment mechanism without the need for frequent maintenance.

[0008] When the plate alignment work is completed, the movable end of the linear drive member moves along the second direction toward the direction away from the alignment surface, and at the same time, the first guide part will move along the extension direction of the first guide groove, and the second guide part will abut against the upper surface of the side plate and move along the second direction; when the first guide part and the second guide part move a certain distance along the second direction, the second guide part will be located at the upper opening of the second guide groove. Since the second guide part loses the support effect exerted by the side plate, the alignment member will rotate around the central axis of the first guide part due to the action of gravity, so that the second guide part can enter the second guide groove and move along the extension direction of the second guide part, prompting the alignment surface to flip from the vertical state to the upward setting, thereby releasing the blocking alignment effect of the alignment surface on the plate, so that the plate after the alignment process can move smoothly along the second direction, and it can also prevent the plate from being scratched by the alignment member.

[0009] In some embodiments of the present invention, a third guide groove is provided on one side of the side plate along the first direction, and a first limiting area and a second limiting area are respectively provided on two opposite sides of the third guide groove along the second direction, the first limiting area is located on a side of the second limiting area away from the alignment surface along the second direction, and a third guide portion is provided on one side or both sides of the alignment member along the first direction, the third guide portion is provided corresponding to the third guide groove, and the center position of the circular arc trajectory is located below the central axis of the first guide portion; When the movable end drives the first guide part to move a first set distance in the second direction, the third guide part moves to the first limiting area so that the second guide part leaves the upper surface of the side plate and enters the second guide groove; then, when the movable end continues to move in the second direction, the first guide part moves along the first guide groove, the second guide part moves downward along the second guide groove, and the third guide part moves from the first limiting area to the direction of the second limiting area; then, when the third guide part moves to the second limiting area, the first guide part and the second guide part move into place, and the alignment surface flips to face upward.

[0010] In some embodiments of the present invention, the center angle of the arc trajectory is less than 90°, the second guide groove is located on the side of the first guide groove away from the alignment surface along the second direction, the third guide groove is located below the first guide groove and on the side of the second guide groove close to the alignment surface along the second direction, when the second guide portion moves along the second direction on the upper surface of the side plate, the third guide portion moves along the second direction on the upper side wall of the third guide groove, and the first limiting area and the second limiting area are respectively located on opposite sides of the upper side wall of the third guide groove along the second direction.

[0011] In some embodiments of the present invention, the alignment member includes a counterweight block and two sub-plates, the two sub-plates are symmetrically arranged about the counterweight block along a first direction and fixedly connected to the counterweight block, the sub-plates are provided with the alignment surface, the counterweight block and the third guide portion are relatively eccentrically arranged, and the center of the first guide portion, the center of the second guide portion and the center of the third guide portion are connected to form an acute triangle.

[0012] In some embodiments of the present invention, the first guide portion, the second guide portion and the third guide portion are rollers, the rollers are rotatably connected to the alignment member, and the central axes of the rollers extend along the first direction; and / or, The plate alignment mechanism also includes a sensing plate and a proximity switch, wherein the sensing plate is fixedly connected to the movable end, and the proximity switch is located below the sensing plate. The proximity switch is used to detect that the sensing plate moves into position along the second direction toward the alignment surface, so as to stop the linear drive component from running.

[0013] A second aspect of the present invention provides a panel saw device, comprising: Plate support mechanism; As described in the first aspect of the embodiment, the plate alignment mechanism is provided with at least two plates, which are arranged at intervals along the first direction, and the plate alignment mechanism is used to align the plates located on the plate support mechanism; A first sawing device, which is used to saw the aligned plates on the plate support mechanism along a first direction; The first plate material feeding device is used to sequentially feed the plate located on the plate supporting mechanism to the plate alignment mechanism and the first sawing device along the second direction.

[0014] The panel saw device according to the second aspect of the embodiment of the present invention has at least the following beneficial effects: when the first plate feeding device feeds the plate located on the plate supporting mechanism to the plate aligning mechanism along the second direction, the plate aligning mechanism contacts the plate through the aligning surface in a vertical state to complete the plate aligning work to improve the sawing accuracy. In this process, since the collision force exerted by the plate on the aligning surface is equal to and opposite to the force exerted by the linear driving component on the aligning component, the linear driving component is not easily damaged, the maintenance frequency is reduced, and the performance requirements and costs are lower. After the plate alignment process is completed, the linear driving component will drive the aligning component to flip over to avoid the aligning component from hindering the movement of the plate toward the first sawing device. Then, the first plate feeding device feeds the plate that has completed the alignment process to the first sawing device, so that the first sawing device performs sawing processing on the plate along the first direction to complete the plate sawing work.

DETAILED DESCRIPTION

[0022] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0023] In the description of the present invention, it is to be understood that a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0024] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] Reference below Figures 1 to 13 The board alignment mechanism and panel saw equipment provided according to the embodiments of the present invention are described.

[0026] like Figures 1 to 5As shown, the plate alignment mechanism 100 according to the first embodiment of the present invention can be applied to plate processing equipment to provide an excellent plate alignment function, especially to align the plate along the plate movement direction before sawing, which helps to improve sawing accuracy. The plate alignment mechanism 100 provided in this embodiment can effectively avoid surface scratches on the plate while achieving the plate alignment function, and the plate alignment mechanism 100 has the advantages of being reliable, durable, not easy to damage and low cost.

[0027] In this embodiment, the plate alignment mechanism 100 has a first direction, a second direction and an up-down direction, the first direction is perpendicular to the second direction and the up-down direction respectively, and the second direction is perpendicular to the up-down direction. Assume that the first direction is the left-right direction and the second direction is the front-back direction.

[0028] like Figures 1 to 5 As shown, the plate alignment mechanism 100 includes an alignment member 110 , a side plate 140 and a linear driving member 130 .

[0029] The alignment piece 110 is provided with an alignment surface on one side along the second direction, and the alignment surface extends in the up-down direction. The alignment surface is a plane, and the side of the plate is in contact with the alignment surface to achieve the plate alignment function. It can be understood that the alignment piece 110 is made of a metal material such as iron, and can withstand the collision from the plate. The height dimension of the alignment surface on the alignment piece 110 can be set according to actual conditions, and multiple stacked plates can be aligned. The shape and size of the alignment piece 110 can be set according to actual needs, and no specific limitation is made here. The alignment surface can be a smooth surface.

[0030] In some examples, the alignment member 110 is provided with an alignment surface, and the alignment surface extends along the up-down direction and the first direction, respectively. In other examples, the alignment member 110 is provided with a plurality of alignment surfaces spaced apart along the first direction.

[0031] Moreover, the first guide portion 180 and the second guide portion 120 are provided on both sides of the alignment member 110 along the first direction. The first guide portions 180 located on opposite sides of the alignment member 110 are symmetrically arranged along the first direction, and the second guide portions 120 located on opposite sides of the alignment member 110 are symmetrically arranged along the first direction. The central axis of the first guide portion 180 and the central axis of the second guide portion 120 both extend along the first direction.

[0032] It is understandable that the first guide portion 180 and the second guide portion 120 can be integrally formed with the alignment member 110, or can be detachably connected to the alignment member 110. The first guide portion 180 and the second guide portion 120 can both guide and restrict the movement of the alignment member 110, so that the alignment member 110 can move along a specific path. Of course, it is not excluded that in other embodiments, the first guide portion 180 and the second guide portion 120 are only provided on one side of the alignment member 110 along the first direction.

[0033] The number of the side plates 140 is consistent with the number of the first guide portions 180 or the second guide portions 120 on the alignment member 110. In this embodiment, the first guide groove 141 and the second guide groove 143 are provided on two opposite side surfaces of the side plate 140 along the first direction, and the openings of the first guide groove 141 and the second guide groove 143 are both opened toward the alignment member 110 along the first direction, and the first guide groove 141 and the second guide groove 143 are arranged at a certain interval along the second direction.

[0034] The length of the first guide groove 141 extends along the second direction, and the first guide groove 141 and the first guide portion 180 are arranged opposite to each other along the first direction. The first guide groove 141 and the first guide portion 180 are adapted to be connected, so that the first guide portion 180 can move linearly along the extension direction of the first guide groove 141, and the alignment member 110 can swing up and down around the central axis of the first guide portion 180. In this embodiment, the first guide groove 141 is a rectangular groove.

[0035] It is understood that, in some examples, the first guide portion 180 is a roller, and the roller is rotatably connected to the alignment member 110 through a rotating shaft, and the central axis of the roller extends along the first direction, and the outer peripheral surface of the roller contacts the upper and lower side walls of the first guide groove 141, so that the roller can roll smoothly in the first guide groove 141, and the friction resistance is small. In other examples, the first guide portion 180 is cylindrical, and is integrally formed with the alignment member 110 or connected by bolts, and the outer peripheral surface of the first guide portion 180 contacts the upper and lower side walls of the first guide groove 141. In some other examples, the first guide portion 180 is a square prism, and the first guide portion 180 can contact the upper and lower side walls of the first guide groove 141, and the first guide portion 180 can only move linearly along the first guide groove 141, and the first guide portion 180 is rotatably connected to the alignment member 110 through a rotating shaft, and the alignment member 110 can rotate relative to the first guide portion 180 around the central axis of the first guide portion 180.

[0036] The length of the second guide groove 143 extends from top to bottom along an arc trajectory, and the center position of the arc trajectory (i.e. Figure 5The second guide groove 143 is located at the side of the second guide groove 143 close to the alignment surface along the second direction. In addition, the second guide groove 143 and the second guide portion 120 are arranged opposite to each other along the first direction, and the second guide groove 143 is adapted to be connected with the second guide portion 120 so that the second guide portion 120 can move along the extension direction of the second guide groove 143. The second guide groove 143 has an upper end opening so that the second guide portion 120 can enter and exit the second guide groove 143. The upper surface of the side plate 140 is a horizontal surface, so that the second guide portion 120 can be pressed against the upper surface of the side plate 140 and can move linearly along the upper surface of the side plate 140.

[0037] It is understandable that the lower end of the second guide groove 143 may be an open structure or a closed structure. The upper end opening of the second guide groove 143 may be provided with a guide chamfer. The second guide groove 143 may be located on the side of the first guide groove 141 away from the alignment surface along the second direction, or may be located on the side of the first guide groove 141 close to the alignment surface along the second direction.

[0038] In some examples, the second guide portion 120 is a roller, which is rotatably connected to the alignment member 110 through a rotating shaft, and the central axis of the roller extends along the first direction. When the roller enters the second guide groove 143, the outer circumference of the roller contacts the two arc-shaped side walls of the second guide groove 143, so that the roller can roll stably in the second guide groove 143. In other examples, the second guide portion 120 is cylindrical and is integrally formed with the alignment member 110 or connected by bolts, and the outer circumference of the second guide portion 120 contacts the two arc-shaped side walls of the second guide groove 143.

[0039] The center position of the arc trajectory is not on the straight line passing through the center of the first guide portion 180 and extending along the second direction. The center position of the arc trajectory is located below the central axis of the first guide portion 180, and the center angle of the arc trajectory is less than 90°. In this embodiment, the center angle of the arc trajectory is 85°. Figures 3 to 5 As shown, the second guide groove 143 is located on the side of the first guide groove 141 away from the alignment surface along the second direction. Then, when the alignment surface is in a vertical state, the second guide portion 120 is located on the side of the first guide portion 180 away from the alignment surface along the second direction, and is located above the first guide portion 180. The center of gravity position of the alignment member 110 is located on the side of the first guide portion 180 away from the alignment surface along the second direction, and is located below the first guide portion 180. Specifically, the center of gravity position of the alignment member 110 is between the first guide portion 180 and the second guide portion 120 in the second direction.

[0040] It is understandable that if Figure 4As shown, when the second guide portion 120 is located at the upper end opening of the second guide groove 143, the supporting effect of the upper surface of the side plate 140 on the second guide portion 120 disappears. At this time, the center of gravity of the alignment member 110 is located on the side of the first guide portion 180 close to the second guide groove 143 along the second direction, so that the alignment member 110 swings up and down due to gravity, so that the second guide portion 120 can enter the second guide groove 143 and move downward along the second guide groove 143. During this process, the first guide portion 180 will move along the first guide groove 141 in the direction close to the second guide groove 143.

[0041] When the alignment member 110 is swung into position, the alignment surface is set upward. At this time, the alignment surface can be set inclined or horizontally, so as to avoid the plate moving along the second direction. Moreover, the center of gravity of the alignment member 110 swings from the side of the first guide portion 180 close to the second guide groove 143 along the second direction to the other side (that is, the side of the first guide portion 180 away from the second guide groove 143 along the second direction), and the first guide portion 180 and the second guide portion 120 stop moving. At the same time, the second guide portion 120 will be hindered from moving upward by the second guide groove 143, so that the alignment member 110 maintains a stable static state.

[0042] Then, when the first guide portion 180 moves linearly along the first guide groove 141 in a direction away from the second guide groove 143, the alignment member 110 automatically swings in the opposite direction due to gravity, so that the second guide portion 120 can move upward along the second guide groove 143; after the second guide portion 120 escapes from the upper end opening of the second guide groove 143, the first guide portion 180 continues to move along the first guide groove 141 in a direction away from the second guide groove 143, and due to the center of gravity of the alignment member 110, the second guide portion 120 can abut against the upper surface of the side plate 140, thereby ensuring that the alignment surface switches from the face-up state to the vertical state. Then, when the first guide portion 180 and the second guide portion 120 move into position along the first guide groove 141 in a direction away from the second guide groove 143, the alignment member 110 can align the plate through the alignment surface.

[0043] Of course, it is not excluded that in other embodiments, the side plate 140 is only provided on one side of the alignment member 110 along the first direction.

[0044] The linear drive member 130 is relatively fixedly arranged with the side plate 140. Specifically, the side plate 140 is provided with a fixed plate 150, and the linear drive member 130 is installed on the fixed plate 150. The linear drive member 130 has a movable end that can move along the second direction, and the movable end of the linear drive member 130 is hinged to the alignment member 110, and the hinge axis of the movable end is colinear with the central axis of the first guide portion 180 along the first direction.

[0045] It is understandable that the linear drive member 130 can be a linear drive device such as a cylinder, a hydraulic cylinder, an electric cylinder, etc. In this embodiment, the linear drive member 130 is a telescopic cylinder, and the movable rod of the telescopic cylinder is provided with a connecting block 131, and the connecting block 131 is provided with a hinge hole extending through along the first direction, and the hinge shaft passes through the hinge hole and is connected to the alignment member 110, so that a hinge relationship is generated between the connecting block 131 and the alignment member 110, so that the alignment member 110 can swing around the hinge shaft.

[0046] After the plate alignment mechanism 100 completes the plate alignment work, it is necessary to switch the plate alignment mechanism 100 from the working state to the non-working state, that is, to switch the alignment surface from the vertical state to the face-up state. Then, by starting the linear drive member 130, the movable end of the linear drive member 130 is moved along the second direction toward the direction away from the alignment surface. At this time, the linear drive member 130 will drive the alignment member 110 to move linearly along the second direction toward the direction away from the alignment surface. In this process, the first guide portion 180 can move along the extension direction of the first guide groove 141, and at the same time, the second guide portion 120 can move along the second direction on the upper surface of the side plate 140. Due to the guiding and limiting effects of the first guide portion 180 and the second guide portion 120, the alignment member 110 can only move linearly along the second direction.

[0047] When the second guide portion 120 moves to the upper end opening of the second guide groove 143, the second guide portion 120 leaves the upper surface of the side plate 140 and loses the support from the side plate 140; then, the alignment member 110 will automatically rotate around the central axis of the first guide portion 180 due to the action of gravity, so that the second guide portion 120 can enter the second guide groove 143 and move downward along the extension direction of the second guide groove 143. At the same time, the first guide portion 180 will continue to move linearly in the original direction until the alignment member 110 swings into place, and the first guide portion 180 and the second guide portion 120 are in a stationary state, so that the alignment surface is flipped from the vertical state to the upward state, so that the plate can move along the second direction without being blocked by the alignment member 110.

[0048] In some embodiments, Figures 1 to 5 As shown, a third guide groove 142 is provided on one side of the side plate 140 along the first direction, and a first limiting area and a second limiting area are provided on opposite sides of the third guide groove 142 along the second direction, respectively, and the first limiting area is located on the side of the second limiting area away from the alignment surface along the second direction. In this embodiment, the third guide groove 142 is located below the first guide groove 141 and on the side of the second guide groove 143 close to the alignment surface along the second direction.

[0049] Moreover, the third guide portion 190 is provided on two opposite side surfaces of the alignment member 110 along the first direction. The third guide portion 190 is provided corresponding to the third guide groove 142. The third guide portion 190 can extend into the third guide groove 142 and move along a specific path in the third guide groove 142. The center position of the arc trajectory is located below the central axis of the first guide portion 180. In the present embodiment, the third guide portion 190 is a roller, which is rotatably connected to the alignment member 110 via a rotating shaft, and the central axis of the roller extends along the first direction. The center of the first guide portion 180, the center of the second guide portion 120 and the center of the third guide portion 190 are sequentially connected to form an acute triangle, such as Figure 5 (a) shown.

[0050] It is understandable that the third guide portion 190 may also be cylindrical and fixedly connected to the alignment member 110. The first limiting area and the second limiting area can exert a limiting effect on the third guide portion 190. In addition, it is not excluded that in other embodiments, the third guide portion 190 is provided on one side of the alignment member 110 along the first direction. The shape of the third guide groove 142 can be set according to actual needs, as long as it has the first limiting area and the second limiting area and allows the third guide portion 190 to move in the third guide groove 142. The first limiting area can limit the amplitude of the clockwise swing of the alignment member 110, and the second limiting area can limit the amplitude of the counterclockwise swing of the alignment member 110.

[0051] like Figures 3 to 5 As shown, in this embodiment, the upper side wall of the third guide groove 142 is a horizontal surface. In addition, the lower end of the third guide groove 142 is an open structure, so that the third guide portion 190 can enter and exit the third guide groove 142. Of course, it is not ruled out that the lower end of the third guide groove 142 is a closed structure. The lower end of the second guide groove 143 is also an open structure, and the arc convex side surface of the second guide groove 143 is longer than the arc concave side surface, so that the second guide portion 120 can always abut against the arc convex side surface of the second guide groove 143.

[0052] It is understandable that if Figure 4 (a) and Figure 5 As shown in (a), when the first guide portion 180 moves linearly along the first guide groove 141 and the second guide portion 120 moves along the second direction on the upper surface of the side plate 140, the third guide portion 190 moves along the second direction on the upper side wall of the third guide groove 142, and the first limiting area and the second limiting area are respectively located on opposite sides of the upper side wall of the third guide groove 142 along the second direction.

[0053] like Figure 4 (b) and Figure 5As shown in (b), after the movable end of the linear drive member 130 drives the alignment member 110 with the first guide part 180, the second guide part 120 and the third guide part 190 to move a first set distance along the second direction away from the alignment surface, the third guide part 190 will move to the first limiting area. At this time, the first limiting area can limit the third guide part 190, so that the third guide part 190 cannot continue to move in a straight line, thereby completing the positioning of the second guide part 120, so that the second guide part 120 is located at the upper end opening of the second guide groove 143, avoiding the situation where the second guide part 120 misses the upper end opening of the second guide groove 143 and cannot enter the second guide groove 143 due to the excessive movement speed of the linear drive member 130, resulting in the failure of the alignment surface to flip, which is beneficial to increase the speed of switching the alignment member 110 to the non-working state and improve the conveying efficiency of the aligned plates.

[0054] Through the cooperation of the first limiting area and the third guide portion 190, the second guide portion 120 can leave the upper surface of the side plate 140 and quickly enter the second guide groove 143. Figure 4 (c) Figure 5 (c) and Figure 5 As shown in (d), when the movable end of the linear drive member 130 continues to move along the second direction, the first guide portion 180 will continue to move along the first guide groove 141 (as can be seen from the vertical center line of the first guide portion 180 in the figure), and the alignment member 110 will rotate around the central axis of the first guide portion 180 relative to the linear drive member 130, so that the second guide portion 120 will move downward along the second guide groove 143, and at the same time, the third guide portion 190 will move from the first limiting area to the second limiting area.

[0055] like Figure 4 (c) and Figure 5 As shown in (c), when the second guide portion 120 does not move to the quadrant point of the arc convex side surface of the second guide groove 143 in the second direction, the second guide portion 120 is supported upward by the arc convex side surface. Figure 5 As shown in (d), when the second guide portion 120 moves to below the quadrant point of the arc convex side surface, the second guide portion 120 is pressed downward by the arc convex side surface.

[0056] The third guide portion 190 moves downward from the first limiting area until it reaches the lowest point. Figure 4 (d) and Figure 5As shown in (e), when the third guide portion 190 moves upward from the lowest point to the second limiting area, the linear drive member 130 stops running, and the second limiting area can limit the third guide portion 190, so that the third guide portion 190 cannot continue to move upward. At this time, the first guide portion 180 and the second guide portion 120 move into place and cannot continue to move in the original direction. The second guide portion 120 is pressed downward by the convex side of the arc, so that the alignment member 110 cannot swing in the opposite direction due to gravity, causing the alignment member 110 to be stationary, and the alignment surface is turned upward to prevent the movement of the plate from being blocked by the alignment member 110.

[0057] When the plate alignment mechanism 100 needs to align the next batch of plates, the linear drive member 130 runs and drives the alignment member 110 to drive the first guide part 180 to move in the opposite direction along the second direction. At this time, the alignment member 110 automatically swings due to gravity, causing the first guide part 180, the second guide part 120 and the third guide part 190 to move in the opposite direction, that is, they return along the original movement path until the alignment surface reaches the set working position and can align the plates.

[0058] The first set distance can be set according to actual needs and is not specifically limited here.

[0059] Of course, it is not excluded that in other embodiments, the upper side wall of the third guide groove 142 is set as a horizontal surface, the lower end of the second guide groove 143 is an open structure, and the arc convex side surface of the second guide groove 143 is longer than the arc concave side surface. In this case, Figure 4 (d) and Figure 5 As shown in (e), during the operation of the linear drive member 130, when the first guide portion 180 moves in the second direction away from the alignment surface, during this process, the second guide portion 120 will first move along the upper surface of the side plate 140, and then move downward along the second guide groove 143, while the third guide portion 190 will first move along the upper side wall of the third guide groove 142, and then move from the first limit area to the second limit area. When the third guide portion 190 moves to the second limit area, the linear drive member 130 stops running, and the first guide portion 180 and the second guide portion 120 both stop moving, so that the alignment surface flips to face upward.

[0060] When the plate alignment mechanism 100 needs to align the next batch of plates, the linear drive member 130 is started and drives the alignment member 110 to continue to move in the original direction with the first guide portion 180. At this time, the third guide portion 190 will move from the second limiting area along the second direction toward the second guide groove 143, and the second guide portion 120 will also move linearly along the second direction, so that the second guide portion 120 leaves the circular arc convex side surface of the second guide groove 143, and the downward pressure of the circular arc convex side surface of the second guide groove 143 is released. Then, the alignment member 110 can swing downward due to the action of gravity.

[0061] Next, when the first guide portion 180 moves to its position, the second guide portion 120 is located at the lower opening of the second guide groove 143 and is about to enter the second guide groove 143. Then, the linear drive member 130 drives the alignment member 110 to move in the opposite direction with the first guide portion 180, so that the second guide portion 120 moves upward along the second guide groove 143, and the third guide portion 190 moves in the direction of the first limiting area. When the third guide portion 190 moves to the first limiting area, the second guide portion 120 just exits from the second guide groove 143; finally, the first guide portion 180 continues to move in the opposite direction, and at the same time, the second guide portion 120 moves linearly on the upper surface of the side plate 140, and the third guide portion 190 moves linearly on the upper side wall of the third guide groove 142.

[0062] In some embodiments, Figures 2 to 5 As shown, the structure of the alignment member 110 includes a counterweight block 112 and two sub-plates 111. The two sub-plates 111 are symmetrically arranged about the counterweight block 112 along the first direction, and the two sub-plates 111 are fixedly connected to the counterweight block 112. The sub-plate 111 is provided with an alignment surface, which is located on one side of the sub-plate 111 along the second direction.

[0063] A first guide portion 180, a second guide portion 120 and a third guide portion 190 are provided on a side of each sub-plate 111 away from the counterweight 112 along the first direction. Specifically, the first guide portion 180 is located at the lower end of the sub-plate 111, and the sub-plate 111 is provided with a first connecting arm and a second connecting arm, the first connecting arm extends along the second direction and is located above the second connecting arm, the second guide portion 120 is provided at the end of the first connecting arm, the second connecting arm extends from top to bottom in a direction away from the aligned surface, and the third guide portion 190 is provided at the end of the second connecting arm.

[0064] The counterweight 112 is eccentrically arranged relative to the third guide portion 190. In the present embodiment, the counterweight 112 is cylindrical, and the central axis of the counterweight 112 extends along the first direction. Moreover, a limit block 113 is arranged on the counterweight 112, and the limit block 113 is located below the connecting block 131, and the limit block 113 can rotate with the counterweight 112 and the sub-plate 111. When the alignment member 110 rotates clockwise until the alignment surface is in a vertical state, the upper surface of the limit block 113 will abut against the lower surface of the connecting block 131, so that the alignment member 110 cannot continue to rotate clockwise. When the alignment member 110 rotates counterclockwise until the alignment surface is in a face-up state, the limit block 113 will abut against the connecting block 131, so that the alignment member 110 cannot continue to rotate counterclockwise.

[0065] In some embodiments, Figures 1 to 3 As shown, the plate alignment mechanism 100 also includes a sensing plate 160 and a proximity switch 170. The sensing plate 160 is fixedly connected to the movable end of the linear drive member 130, and the sensing plate 160 can move along the second direction following the movable end of the linear drive member 130. Specifically, the sensing plate 160 is fixed to the upper surface of the connecting block 131 by bolts. The sensing plate 160 can be an iron plate, which can trigger the proximity switch 170.

[0066] The proximity switch 170 is located below the sensing plate 160, and the proximity switch 170 is used to detect that the sensing plate 160 moves in the second direction toward the alignment surface to stop the linear drive member 130 and make the alignment surface in a set working position. The proximity switch 170 can be used in conjunction with a control device such as a PLC controller, so that the control device controls the linear drive member 130 to stop working after receiving the detection signal of the proximity switch 170.

[0067] Of course, it is not excluded that in other embodiments, the position control of the first guide portion 180 in the second direction is achieved by cooperating with the control device through the sensing plate 160 and the proximity switch 170 so as to locate the third guide portion 190 in the second limiting area.

[0068] In the plate alignment mechanism 100 provided in the embodiment of the first aspect of the present invention, when the alignment member 110 is in working state, the alignment surface on the alignment member 110 extends in the up and down directions, and can align the plate. In this process, since the collision force exerted by the plate on the alignment surface and the force exerted by the linear drive member 130 on the alignment member 110 are collinearly arranged in the second direction, the force exerted by the linear drive member 130 on the alignment member 110 is equal to the collision force and can relatively offset each other. Therefore, the performance requirements and cost of the linear drive member 130 can be reduced, and the linear drive member 130 can be prevented from easily failing due to the large collision force, thereby extending the service life of the plate alignment mechanism 100 without the need for frequent maintenance.

[0069] When the plate alignment work is completed, the movable end of the linear drive member 130 moves along the second direction toward the direction away from the alignment surface. At the same time, the first guide portion 180 moves along the extension direction of the first guide groove 141, and the second guide portion 120 abuts against the upper surface of the side plate 140 and moves along the second direction; when the first guide portion 180 and the second guide portion 120 move a certain distance along the second direction, the second guide portion 120 is located at the upper opening of the second guide groove 143. Since the second guide portion 120 loses the support effect of the side plate 140, the alignment member 110 rotates around the central axis of the first guide portion 180 due to gravity, so that the second guide portion 120 can enter the second guide groove 143 and move along the extension direction of the second guide portion 120, so that the alignment surface is flipped from the vertical state to the upward setting, thereby releasing the blocking alignment effect of the alignment surface on the plate, so that the plate after the alignment process can move smoothly along the second direction, and the plate can be prevented from being scratched by the alignment member 110.

[0070] like Figures 1 to 7 As shown, the panel saw device according to the second embodiment of the present invention can perform panel cutting processing on one or more panels.

[0071] In this embodiment, the panel saw device includes a panel support mechanism 200, a first sawing device 410, a first panel feeding device 310 and the panel alignment mechanism 100 of the first embodiment.

[0072] The sheet support mechanism 200 is provided with a sheet support surface, and the function of the sheet support mechanism 200 is to support the sheet. It is understandable that the sheet support mechanism 200 can be a support table 800 with multiple rollers or universal balls or rollers, or a workbench. The two ends of the sheet support mechanism 200 along the first direction are a feed end and a discharge end, respectively.

[0073] At least two plate alignment mechanisms 100 are provided, and all the plate alignment mechanisms 100 are arranged at certain intervals along the first direction. The plate alignment mechanisms 100 are used to align the plates on the plate support mechanism 200 .

[0074] The first sawing device 410 is arranged near the discharge end of the sheet support mechanism 200, and the sheet alignment mechanism 100 is located on the side of the first sawing device 410 near the feed end. The function of the first sawing device 410 is to saw the aligned sheet on the sheet support mechanism 200 along the first direction. It can be understood that the first sawing device 410 is a prior art, and the sheet is sawed by moving the rotating saw blade along the first direction. In addition, a pressure plate device can be arranged above the sheet support mechanism 200, and the pressure plate device presses down the sheet on the sheet support surface through a pressure beam that can move up and down, so that the first sawing device 410 can stably saw the sheet.

[0075] The first sheet material feeding device 310 is arranged above the sheet material supporting mechanism 200. The function of the first sheet material feeding device 310 is to sequentially feed the sheet material on the sheet material supporting mechanism 200 to the sheet material alignment mechanism 100 and the first sawing device 410 along the second direction. It is understandable that the first sheet material feeding device 310 is a prior art, which can clamp the sheet material and push the sheet material to move along the second direction. For example, the first sheet material feeding device 310 can adopt a gripping plate manipulator mechanism disclosed in the invention patent application document with publication number CN106965261A, which is not described in detail here. The first sheet material feeding device 310 can push the sheet material to the sheet material alignment mechanism 100. After the sheet material is aligned, the first sheet material feeding device 310 clamps the sheet material and feeds the sheet material to the first sawing device 410 for sheet cutting.

[0076] In the panel saw device of the present embodiment, when the first plate material feeding device 310 feeds the plate material located on the plate material supporting mechanism 200 to the plate material alignment mechanism 100 along the second direction, the plate material alignment mechanism 100 contacts the plate material through the alignment surface in a vertical state to complete the plate material alignment work to improve the sawing accuracy. In this process, since the collision force exerted by the plate material on the alignment surface is equal to and opposite to the force exerted by the linear driving member 130 on the alignment member 110, the linear driving member 130 is not easily damaged, the maintenance times are reduced, and the performance requirements and costs are lower. After the plate material alignment process is completed, the linear driving member 130 will drive the alignment member 110 to flip to prevent the alignment member 110 from hindering the movement of the plate material toward the first sawing device 410. Then, the first plate material feeding device 310 feeds the plate material that has completed the alignment process to the first sawing device 410, so that the first sawing device 410 performs sawing process on the plate material along the first direction to complete the plate material sawing work.

[0077] In some embodiments, Figure 6 and Figure 7As shown, the panel saw device further includes a plate lifting device 600. The plate lifting device 600 is located on a side of the plate support mechanism 200 away from the first sawing device 410 along the second direction, that is, the plate lifting device 600 is arranged close to the feeding end of the plate support mechanism 200. It can be understood that the plate lifting device 600 can be a prior art, and the height position of the stacked plates can be adjusted by a liftable lifting frame, so that the plates are moved from bottom to top to a set position.

[0078] The first plate feeding device 310 is also used to transfer the plate on the plate lifting device 600 to the plate supporting mechanism 200, so that there is no need to manually load the plate. It can be understood that the first plate feeding device 310 includes a gripping plate manipulator mechanism and a thickness-setting push plate mechanism. The thickness-setting push plate mechanism can accurately measure the thickness of the plate, and push multiple stacked plates from the plate lifting device 600 along the second direction to the plate supporting mechanism 200, and then push them to the plate alignment mechanism 100 to complete the plate alignment work, so that the gripping plate manipulator mechanism can clamp and convey the aligned plates. The thickness-setting push plate mechanism can be integrated with the gripping plate manipulator mechanism and can move synchronously, or it can be separated from the gripping plate manipulator mechanism and can move and work independently. The thickness-setting push plate mechanism can adopt a thickness-setting push device disclosed in the invention patent application document with publication number CN103950071A, which will not be described in detail here.

[0079] In this embodiment, if Figures 10 to 13 As shown, the structure of the plate lifting device 600 includes a support assembly 610, a lifting assembly 630, a hydraulic system, a guide wheel assembly 620, a transition wheel assembly 650 and a wire rope 660.

[0080] The support assembly 610 includes four columns 611, and the four columns 611 are arranged in a matrix. It can be understood that the columns 611 are made of metal materials such as iron, have high strength, and are not prone to bending and deformation. The columns 611 are fixed to the ground by ground screws. The shape and size of the columns 611 can be set according to actual needs and are not specifically limited here. In this embodiment, the support assembly 610 also includes a connecting rod. Specifically, the four columns 611 are arranged at intervals along the first direction and the second direction, respectively, and at least one connecting rod is provided between the two columns 611 arranged at intervals along the second direction. The connecting rod extends along the second direction, and the connecting rod is vertically connected to the column 611 to enhance the stability of the column 611 relative to the ground, so that the column 611 is not easy to tip over.

[0081] The lifting assembly 630 is provided with a support surface, and the function of the support surface is to support the plate. It is understandable that the support surface is a horizontal surface, which can stably support a plurality of plates neatly stacked in the vertical direction. The area of ​​the support surface is larger than the surface area of ​​the plate. The lifting assembly 630 can move the plate in the vertical direction relative to the column 611 to achieve the function of lifting the plate. The lifting assembly 630 can be set in the area surrounded by the four columns 611.

[0082] Moreover, a lifting drive mechanism is arranged between the lifting assembly 630 and the supporting assembly 610 , and the lifting drive mechanism mainly includes a hydraulic system, a guide wheel assembly 620 , a transition wheel assembly 650 and a wire rope 660 .

[0083] The hydraulic system includes a hydraulic cylinder 640 and a pump station. The hydraulic cylinder 640 is arranged on the lifting assembly 630, and the hydraulic cylinder 640 is located below the support surface to prevent the hydraulic cylinder 640 from obstructing the plate from being placed on the support surface. At the same time, the space below the support surface can be effectively utilized to install the hydraulic cylinder 640, reducing the occupied area on the horizontal surface. The movable end of the hydraulic cylinder 640 is configured to be able to extend and retract in the horizontal direction. The pump station is connected to the hydraulic cylinder 640 through a pipeline to form a hydraulic circuit.

[0084] In some examples, the pump station is disposed on the lifting assembly 630 and can move with the lifting assembly 630. In other examples, the pump station is disposed on the ground and the lifting assembly 630 can move up and down relative to the pump station.

[0085] It is understandable that the hydraulic cylinder 640 can be fixedly mounted on the lifting assembly 630 by bolts, so that the hydraulic cylinder 640 can move along the up and down direction with the lifting assembly 630. The hydraulic cylinder 640 is an actuator in the hydraulic system, which converts hydraulic energy into mechanical energy to push the load to work. The hydraulic cylinder 640 has the advantages of simple structure, reliable operation, easy maintenance and maintenance. The pump station (also known as the hydraulic pump station) is the power source in the hydraulic system. It is mainly composed of hydraulic pumps, motors, oil tanks, control valves and other components. The pump station drives the hydraulic pump to rotate through the motor, converts mechanical energy into pressure energy of hydraulic oil, and provides the required pressure and flow for the hydraulic system. The hydraulic oil output by the hydraulic pump can be delivered to the hydraulic cylinder 640 along a specific path, and the flow direction, pressure and flow of the hydraulic oil are controlled, thereby realizing various actions and functions of the hydraulic system.

[0086] There are four guide wheel assemblies 620 , and the four guide wheel assemblies 620 are respectively arranged corresponding to the four columns 611 , each guide wheel assembly 620 is slidably connected to the corresponding column 611 along the up and down direction, and all the guide wheel assemblies 620 are fixedly connected to the lifting assembly 630 .

[0087] It is understandable that the guide wheel assembly 620 includes a guide wheel and a guide wheel seat, the guide wheel seat is connected to the lifting assembly 630 by bolts, and the guide wheel seat can be installed on the column 611 through a slide rail slider pair or a combination of an optical axis and a guide sleeve, so that the guide wheel seat can be smoothly raised and lowered relative to the column 611. The guide wheel is installed on the guide wheel seat through a rotating shaft, and the central axis of the guide wheel extends in the horizontal direction. The guide wheel has an annular wire groove for the wire rope 660 to be wound. The guide wheel can guide the wire rope 660 to change the extension direction of the wire rope 660, so that the extension direction of the wire rope 660 changes by 90°. The wire rope 660 can be wound around the guide wheel for one or more turns, or it can be wound around the guide wheel for less than one turn.

[0088] In some examples, the extension direction of the central axis of the guide wheel assembly 620 is consistent with the extension direction of the movable end of the hydraulic cylinder 640, for example, both extend in the first direction. In other examples, the extension direction of the central axis of the guide wheel assembly 620 is inconsistent with the extension direction of the movable end of the hydraulic cylinder 640, for example, the two are perpendicular to each other, the extension direction of the movable end of the hydraulic cylinder 640 is the first direction, and the central axis of the guide wheel assembly 620 extends in the second direction.

[0089] There are multiple transition wheel assemblies 650, and the multiple transition wheel assemblies 650 are arranged on the lifting assembly 630. The transition wheel assembly 650 is located below the supporting surface, and the central axis of the transition wheel assembly 650 extends in the up-down direction.

[0090] It can be understood that the transition wheel assembly 650 includes a transition wheel and a mounting seat, the mounting seat is connected to the lifting assembly 630 by bolts, the transition wheel is set on the mounting seat through the wheel axle, the central axis of the transition wheel extends in the up and down direction, the transition wheel also has an annular wire groove for the wire rope 660 to be wound, and the transition wheel can guide the wire rope 660 to change the extension direction of the wire rope 660, so that the extension direction of the wire rope 660 changes by 90°. Similarly, the wire rope 660 can be wound around the transition wheel for one circle or more, or it can be wound around the transition wheel for less than one circle. The mounting seat can be integrally formed with the lifting assembly 630, that is, the mounting seat is a part of the structure of the lifting assembly 630.

[0091] Four steel wire ropes 660 are provided, and the four steel wire ropes 660 are respectively arranged corresponding to the four columns 611. The upper end of each steel wire rope 660 is fixedly connected to the column 611, and the lower end of each steel wire rope 660 passes through the guide wheel assembly 620 and the corresponding transition wheel assembly 650, and is fixedly connected to the movable end of the hydraulic cylinder 640. The function of the hydraulic cylinder 640 is to drive the lower ends of all the steel wire ropes 660 to move in the same direction, so that the lifting assembly 630 moves in the up and down direction.

[0092] It can be understood that the upper end of the wire rope 660 is fixedly connected to the upper end of the column 611, and the wire rope 660 extends vertically downward along the column 611, and changes the extension direction of the wire rope 660 on the vertical plane by winding around the guide wheel assembly 620, so that the wire rope 660 extends horizontally from the guide wheel assembly 620. At this time, if the extension direction of the wire rope 660 is consistent with the extension direction of the movable end of the hydraulic cylinder 640, the wire rope 660 can be directly fixedly connected to the movable end of the hydraulic cylinder 640; if the extension direction of the wire rope 660 is inconsistent with the extension direction of the movable end of the hydraulic cylinder 640, the wire rope 660 will change the extension direction of the wire rope 660 on the horizontal plane by winding around the transition wheel assembly 650, so that the wire rope 660 extends horizontally from the transition wheel assembly 650, and the extension direction is consistent with the extension direction of the movable end of the hydraulic cylinder 640, so that the wire rope 660 can be fixedly connected to the movable end of the hydraulic cylinder 640.

[0093] In this embodiment, the column 611 is provided with a cavity which is open toward the lifting assembly 630, and the wire rope 660 and the guide wheel assembly 620 can be partially located in the cavity, thereby preventing the guide wheel assembly 620 and the wire rope 660 from being obstructed by the outside world.

[0094] In some embodiments, Figures 10 to 13 As shown, the lifting assembly 630 includes a lifting bracket 631 and a roller conveying mechanism 632 .

[0095] The roller conveying mechanism 632 is arranged above the lifting bracket 631, and the roller conveying mechanism 632 is fixedly connected to the lifting bracket 631, and the roller conveying mechanism 632 is provided with a support surface. It can be understood that the roller conveying mechanism 632 is a prior art, which mainly includes a plurality of conveying rollers arranged side by side and an electric drive device for driving the conveying rollers to rotate, and the conveying direction of the roller conveying mechanism 632 can be set to a first direction or a second direction. All the conveying rollers jointly define the support surface.

[0096] In addition, in some embodiments, the roller conveyor mechanism 632 is provided with at least two forklift slots 633, and the openings of the forklift slots 633 are open upward. The forklift slots 633 are arranged to avoid the conveying rollers in the roller conveyor mechanism 632. With this design, the staff can transfer the stacked plates to the support surface of the roller conveyor mechanism 632 by forklift.

[0097] The lifting bracket 631 can be a frame formed by connecting multiple profiles vertically and horizontally. The hydraulic cylinder 640, the guide wheel assembly 620 and the transition wheel assembly 650 are all arranged on the lifting bracket 631. The hydraulic cylinder 640, the guide wheel assembly 620, the transition wheel assembly 650 and the roller conveying mechanism 632 can move along the up and down direction together with the lifting bracket 631. The lifting bracket 631 is provided with a mounting plate 642, and the pump station is set on the mounting plate 642 by bolts. Such a setting allows the hydraulic system to rise and fall with the lifting bracket 631, avoiding the situation where the pipeline between the pump station and the hydraulic cylinder 640 is designed to be longer due to the pump station being set on the ground to meet the conditions for the lifting of the hydraulic cylinder 640.

[0098] Of course, it is not excluded that in other embodiments, the lifting assembly 630 only includes the lifting bracket 631 .

[0099] In some embodiments, Fig.11 and Fig.13 As shown, the movable end of the hydraulic cylinder 640 can be extended and retracted along the first direction, a transition wheel assembly 650 is provided on the opposite sides of the hydraulic cylinder 640 along the first direction, and two guide wheel assemblies 620 are provided on the opposite sides of the lifting bracket 631 along the second direction. Moreover, the two guide wheel assemblies 620 are arranged at a certain interval along the first direction, and the central axis of the guide wheel assembly 620 extends along the first direction.

[0100] In this embodiment, if Fig.11 and Fig.13 As shown, two transition wheel assemblies 650 located on opposite sides of the lifting bracket 631 along the first direction are arranged opposite to each other, and two guide wheel assemblies 620 located on opposite sides of the lifting bracket 631 along the second direction are arranged symmetrically. The four guide wheel assemblies 620 are respectively arranged at the four corners of the lifting bracket 631.

[0101] Moreover, the transition wheel assembly 650 disposed near the movable end of the hydraulic cylinder 640 is set as the first transition wheel assembly 650, and the transition wheel assembly 650 disposed away from the movable end of the hydraulic cylinder 640 is set as the second transition wheel assembly 650.

[0102] Two of the steel wire ropes 660 (i.e., the two steel wire ropes 660 located on the left side of the hydraulic cylinder 640) are passed around the first transition wheel assembly 650 and the second transition wheel assembly 650 in sequence, and are fixedly connected to the movable end of the hydraulic cylinder 640. Fig.13As shown, taking the wire rope 660 in the upper left corner as an example, the upper end of the wire rope 660 is fixedly connected to the corresponding column 611, and the wire rope 660 extends downward and bypasses the guide wheel assembly 620 located below it, so that the wire rope 660 extends in the second direction, changing the extension direction of the wire rope 660 on the vertical plane; then, the wire rope 660 bypasses the first transition wheel assembly 650, so that the wire rope 660 extends in the first direction, changing the extension direction of the wire rope 660 on the horizontal plane; then, the wire rope 660 bypasses the second transition wheel assembly 650, so that the wire rope 660 extends in the opposite direction of the first direction, and is fixedly connected to the connecting head 641 provided at the movable end of the hydraulic cylinder 640.

[0103] The other two steel wire ropes 660 (i.e., the two steel wire ropes 660 located on the right side of the hydraulic cylinder 640) pass around the second transition wheel assembly 650 and are fixedly connected to the movable end of the hydraulic cylinder 640. Fig.13 As shown, taking the wire rope 660 in the upper right corner as an example, the upper end of the wire rope 660 is fixedly connected to the corresponding column 611, and the wire rope 660 extends downward and bypasses the guide wheel assembly 620 located below it, so that the wire rope 660 extends along the second direction, changing the extension direction of the wire rope 660 on the vertical plane; then, the wire rope 660 bypasses the second transition wheel assembly 650, so that the wire rope 660 extends along the first direction, changing the extension direction of the wire rope 660 on the horizontal plane, and finally the wire rope 660 is fixedly connected to the connecting head 641 provided at the movable end of the hydraulic cylinder 640.

[0104] In some embodiments, Fig.11 and Fig.13 As shown, the first transition wheel assembly 650 includes two first transition wheels, which are coaxially arranged, and the central axis of the first transition wheel extends in the up-down direction. The two first transition wheels are respectively arranged corresponding to two steel wire ropes 660 (i.e., the two steel wire ropes 660 located at the upper left corner and the lower left corner).

[0105] Moreover, each second transition wheel assembly 650 includes four second transition wheels, which are coaxially arranged, and the central axis of the second transition wheel extends in the up-down direction. The four second transition wheels are respectively arranged corresponding to the four steel wire ropes 660. The first transition wheel and the second transition wheel are both rotatably connected to the lifting bracket 631, so that each first transition wheel and each second transition wheel can rotate relative to the lifting bracket 631. With such a design, the steel wire rope 660 can drive the first transition wheel or the second transition wheel to rotate, avoiding the steel wire rope 660 from being worn too quickly due to the sliding friction between the steel wire rope 660 and the first transition wheel or the second transition wheel, which is beneficial to prolonging the service life of the steel wire rope 660.

[0106] In a specific embodiment, two second transition wheels are fixedly connected and arranged adjacent to each other; another two second transition wheels are fixedly connected and arranged adjacent to each other. Of course, it is not excluded to use a transition wheel with two annular wire grooves to replace the two first transition wheels or the two second transition wheels.

[0107] In other embodiments, the first transition wheel assembly 650 includes a first transition wheel having two annular wire grooves. When the two steel ropes 660 are wound around the first transition wheel, since the winding directions of the two steel ropes 660 are opposite, when the hydraulic cylinder 640 is working, the two steel ropes 660 will slide relative to the first transition wheel.

[0108] Moreover, the second transition wheel assembly 650 includes a second transition wheel having four annular wire grooves. When four steel ropes 660 are wound around the second transition wheel, since two of the steel ropes 660 are in opposite winding directions to the other two steel ropes 660, when the hydraulic cylinder 640 is operating, all the steel ropes 660 will slide relative to the second transition wheel.

[0109] In some embodiments, Figures 10 to 13 As shown, two through holes 634 are provided on the two opposite side surfaces of the lifting bracket 631 along the second direction, and the through holes 634 are used for allowing the steel wire rope 660 to pass through and be wound around the transition wheel assembly 650. It can be understood that the shape and size of the through holes 634 are not limited, as long as they are sufficient for the steel wire rope 660 to pass through. With such a design, it is not necessary to route the steel wire rope 660 through the space below the lifting bracket 631.

[0110] In some embodiments, a fall arrester is provided between the guide wheel assembly 620 and the column 611. The fall arrester can play a role of rapid braking and locking to prevent the lifting assembly 630 from falling suddenly when a power failure occurs. It can be understood that the fall arrester is a prior art, and specifically, a fall arrester for elevators can be used.

[0111] In this embodiment, the column 611 is provided with a guide rod extending in the up and down directions, the guide rod is located in the cavity of the column 611, and the fall arrester is installed on the guide wheel assembly 620. When the lifting assembly 630 suddenly slides down, the fall arrester will lock the guide rod to achieve braking lock and prevent the lifting assembly 630 from falling to the ground or hitting the staff.

[0112] Since the upper ends of the four steel wire ropes 660 are fixedly connected to the corresponding columns 611, and the lower ends of the steel wire ropes 660 are fixedly connected to the movable end of the hydraulic cylinder 640 after passing around the guide wheel assembly 620 and the corresponding transition wheel assembly 650, when the stacked plates are placed on the supporting surface of the lifting assembly 630, the hydraulic cylinder 640 is started, so that the movable end of the hydraulic cylinder 640 can drive the lower ends of the four steel wire ropes 660 to move linearly in the same direction, so that the lifting assembly 630 can move the plates up a certain distance under the action of the four steel wire ropes 660, thereby completing the plate lifting work.

[0113] In this embodiment, a structure consisting of a wire rope 660, a guide wheel assembly 620, a transition wheel assembly 650 and a hydraulic cylinder 640 is arranged between the column 611 and the lifting assembly 630. The same hydraulic cylinder 640 is used to quickly pull all the wire ropes 660, so that the lifting assembly 630 can be raised and lowered quickly and stably. In addition, the number of parts is small, maintenance is convenient, and the manufacturing cost and operating cost are low.

[0114] Compared with the chain drive method, the plate lifting device 600 provided in this embodiment is more reliable and durable, does not require frequent maintenance, and has lower cost; compared with the drive method of the wire rope 660 and the counterweight block 112, it has a simple structure, saves the counterweight block 112, simplifies the installation work, and reduces the cost; compared with the screw drive method, it has a faster lifting speed, high transmission efficiency, low energy consumption and cost, and does not require regular inspection and maintenance; compared with the scissors-type lifting mechanism drive method, on-site installation is simple and convenient, and there is no need to set up a foundation pit.

[0115] In some embodiments, Figure 8 and Fig. 9 As shown, the panel saw device also includes a supporting device, an aligning device, a second sawing device 420 and a second board feeding device. In this case, the panel saw device is a longitudinal and transverse saw, which can simultaneously realize longitudinal and transverse cutting of the board.

[0116] The support device is arranged on one side of the sheet support mechanism 200 close to the first sawing device 410 along the second direction to receive the sawn sheet. It can be understood that the two opposite ends of the support device along the first direction are the sheet feeding end and the sheet discharging end, respectively, and the discharging end of the sheet support mechanism 200 is connected to the sheet feeding end of the support device. The first sawing device 410 can cut one or more sheets to cut each sheet into a plurality of narrow strips, thereby completing the longitudinal cutting of the sheet. Then, the narrow strips are transferred from the sheet support mechanism 200 to the support device.

[0117] The function of the alignment device is to align the plates on the support device along the first direction and the second direction. It is understandable that the alignment device can be a prior art, which can align the plurality of narrow and long plates in the second direction and the first direction, so that the second plate feeding device can clamp the plates. The alignment device can include a first plate side alignment device, a second plate side alignment device, and a plate front alignment device disclosed in the utility model patent document with announcement number CN206883812U.

[0118] The second sawing device 420 is arranged near the sheet material discharge end of the support device, and the alignment device is located on the side of the second sawing device 420 near the sheet material feeding end. The second sawing device 420 is used to saw the aligned sheet material on the support device along the second direction. It can be understood that the second sawing device 420 is a prior art, and the structure of the second sawing device 420 can be the same as that of the first sawing device 410. The first sawing device 410 can cut the sheet material longitudinally, and the second sawing device 420 can cut the sheet material transversely after longitudinal cutting.

[0119] The second plate feeding device is disposed above the supporting device, and is used to sequentially feed the plate on the supporting device to the aligning device and the second sawing device 420 along the first direction. The second plate feeding device may have the same structure as the first plate feeding device 310.

[0120] In this embodiment, the support device includes an air flotation table 710 and a support table 800, which are arranged along a first direction and connected to each other. The air flotation table 710 is connected to the discharge end of the plate support mechanism 200, and the alignment device and the second sawing device 420 are arranged on the support table 800. The support table 800 includes a plurality of support table 800 plates arranged at intervals along the first direction.

[0121] The alignment device includes a first alignment mechanism 910 and a second alignment mechanism 920. The first alignment mechanism 910 can align the plate on the support platform 800 in a first direction, and the second alignment mechanism 920 can align the plate on the support platform 800 in a second direction. The first alignment mechanism 910 can use a plurality of support plates that can be turned upside down, and the support plates can be turned by a cylinder or a motor. The second alignment mechanism 920 can use a plurality of support wheels that can rotate on a horizontal plane, and the support wheels are arranged in the gap between two adjacent support platform 800 plates, and the support wheels can be driven by a driving device such as a cylinder, a screw drive mechanism, etc. to move linearly along the second direction. In addition, the support wheels can be turned upside down by a cylinder.

[0122] The second plate feeding device includes a clamping device 320 and a push plate device 720. The clamping device 320 is arranged above the support table 800. The clamping device 320 can be an existing plate grabbing manipulator. The push plate device 720 is arranged above the air flotation table 710. The push plate device 720 is an existing technology and can drive the push plate to move along the first direction through a servo linear drive mechanism to achieve the push plate work. The push plate device 720 can push the longitudinally cut plate from the air flotation table 710 to the support table 800, and then push it to the alignment device to complete the plate alignment work; then, the clamping device 320 can clamp the aligned plate on the support table 800 to send the plate to the second sawing device 420.

[0123] In some embodiments, Figures 6 to 8 As shown, the panel saw device further includes a residual material dropping device 500. The residual material dropping device 500 is arranged between the plate support mechanism 200 and the support device, and is used to flip and dump the residual material of the plate cut by the first sawing device 410 downward.

[0124] It is understandable that the residual material blanking device 500 is a prior art, and the residual material blanking mechanism disclosed in the invention patent application document with publication number CN106965261A can be used to dump the residual material of the plate generated during the sawing process through a reversible roller table, so that the residual material of the plate falls into the recycling box, thereby realizing the recycling of the residual material of the plate. Of course, it is not ruled out that a table plate can be used instead of a roller table.

[0125] When using the panel saw device that can simultaneously realize longitudinal cutting and transverse cutting provided by the present embodiment, the plate to be processed can be delivered to the plate lifting device 600 by a forklift. Then, the thickness of the plate is accurately measured by the plate-setting push plate mechanism, and a set number of plates are pushed from the plate lifting device 600 to the plate supporting mechanism 200, so that multiple plates can be loaded at the same time. Next, the plate alignment mechanism 100 is used to align the plates. After the alignment process is completed, the plate gripping manipulator mechanism is used to clamp the plates so that the first sawing device 410 can perform longitudinal cutting. The remaining material of the plate cut by the first saw of the first sawing device 410 falls down and is recovered through the remaining material dropping device 500. Then, the first sawing device 410 can perform longitudinal cutting of the plate as required.

[0126] The longitudinally cut plate will be sent to the air-floating table 710 by the plate-grabbing robot mechanism, and then the plate will be pushed from the air-floating table 710 to the support table 800 by the plate-pushing device 720, and the plate will be aligned in the first direction and the second direction by the alignment device. After the alignment work is completed, the plate will be sent to the second sawing device 420 by the clamping device 320 so that the second sawing device 420 can perform cross-cutting.

[0127] In this embodiment, the longitudinal cutting work and the cross-cutting work can be performed simultaneously, which can avoid manual turning of the board, save sawing time, and avoid excessive waste of the board, save the board, and ensure the sawing accuracy. Before the longitudinal cutting work, the size of the board is large, and multiple large boards are stacked in the vertical direction. At this time, the contact surface between the alignment member 110 of the board alignment mechanism 100 and the large board is small, and the board alignment work can also be completed. Before the cross-cutting work, the large board has been longitudinally cut into multiple narrow and long strips of board, and the alignment device needs to provide a sufficiently large contact surface to flush the board.
