Description

Technical Field

[0001] The present invention relates to the technical field of plate processing equipment, and in particular to a single plate turning machine and a plate processing production line using the single plate turning machine. Background Art

[0002] In the prior art, a plate turning machine generally includes a motor and a rotating shaft, with blades or connecting plates evenly installed along the radial direction of the rotating shaft. The plate is horizontally placed on any blade or connecting plate, and the driving motor drives the rotating shaft to rotate, so that the plate is turned over for processing, or the horizontal plate is vertically dropped into the transfer mechanism for storage and waiting for transfer after the blades rotate. This type of structural setting is not suitable for the flipping needs of stacked plates at the same time, and cannot improve the efficiency of batch flipping and transfer of plates, because when flipping, the stacked plates are flipped in a certain order, and are very easy to scatter or even fly randomly during the flipping process. It is extremely difficult to effectively control the landing point of the plates, which seriously affects the effectiveness and safety of the flipping work. On the other hand, due to the limitations of the specifications of the blades or connecting plates, the specifications of the plates that can be placed on the blades are also greatly limited to prevent most of the plates from being exposed outside the blades. The center of gravity of the plates is outside the blades, and they are very easy to slide off the blades, which seriously affects the flipping effect. Summary of the Invention

[0003] The object of the present invention is to provide a single board turning machine, aiming to solve the technical problems of turning over stacked boards and improving the applicability of the turning machine.

[0004] To achieve the above-mentioned purpose, the present invention proposes a single board turning machine, which is applied to a plate processing production line and comprises:

[0005] A frame, wherein the frame is provided with a rotating shaft, wherein the axis of the rotating shaft is parallel to the horizontal ground;

[0006] a turntable, the turntable being coaxially mounted on the rotating shaft;

[0007] 4 blade structures, the 4 blade structures are installed at intervals on a side of the turntable away from the frame, the blade structure includes a first connecting plate, a second connecting plate and a third connecting plate, the first connecting plate is parallel to the horizontal ground, the second connecting plate is connected to a side edge of the first connecting plate and is perpendicular to the first connecting plate, the third connecting plate is perpendicular to the horizontal ground, both sides of the third connecting plate are connected to the first connecting plate and the second connecting plate on a side facing the turntable, and the third connecting plate is installed on the turntable; the 4 blade structures are enclosed to form an open cross-shaped chamber;

[0008] A motor, the motor being mounted on the frame and drivingly connected to the rotating shaft;

[0009] The plate is fed horizontally into the cross-shaped chamber from a side of the turntable away from the frame so that the blade structure supports the plate. The motor drives the turntable to rotate so that the plate is separated from the cross-shaped chamber in a vertical direction.

[0010] Optionally, in the height direction, a plurality of first connection holes are provided on the surface of the turntable, second connection holes are provided on the surface of the third connection plate corresponding to the first connection holes, and the third connection plate connects the first connection holes and the second connection holes through a screw structure.

[0011] Optionally, a flange structure is provided on one side of the first connecting plate and the second connecting plate facing away from the turntable, and the flange structure extends in a direction away from the cross-shaped chamber.

[0012] Optionally, the blade structure further includes a fourth connecting plate, both sides of which are connected to one side of the first connecting plate and the second connecting plate facing away from the turntable.

[0013] Optionally, a side of the blade structure facing the cross-shaped chamber is a smooth planar structure.

[0014] The present invention also proposes a plate processing production line, including the single-plate turning machine described above. The plate processing production line also includes a conveyor belt mechanism and a plate transfer mechanism. The conveyor belt mechanism is used to horizontally deliver the plate from the side of the turntable away from the frame into the cross-shaped chamber so that the blade structure supports the plate. The motor drives the turntable to rotate so that the plate can separate from the cross-shaped chamber in the vertical direction and fall vertically into the plate transfer mechanism.

[0015] Optionally, the conveyor belt mechanism includes an upper conveyor belt and a lower conveyor belt, the lower conveyor belt supports the plate, and the upper conveyor belt is located above the plate and is in close contact with the surface of the plate.

[0016] In the technical solution of the present invention, the plate enters the cross-shaped chamber in the horizontal direction from the side facing away from the turntable. The lower surface of the plate is supported by the blade structure, and the upper surface of the plate is limited by the blade structure. Since the cross-shaped chamber is open, in the horizontal direction, even if the surface area (length and width) of the plate is larger than the maximum cross-sectional area of ​​the cross-shaped chamber, the edge of the plate is exposed outside the cross-shaped chamber, but as long as the center of gravity of the plate is in the cross-shaped chamber, the plate will be stably supported, so that the turning machine of the present invention can meet the use requirements of plates of different specifications. The motor drives the turntable to rotate ninety degrees, which can make the plate slide from the vertical direction and gradually leave the cross-shaped chamber. During the turning process, the stacked plates are limited by the blade structure to achieve the technical effect of reducing or preventing the plates from dispersing.

[0027] In an embodiment of the present invention, the single board turning machine 100 is applied to a plate processing production line 200, and the single board turning machine 100 includes: a frame 1, the frame 1 is equipped with a rotating shaft 11, and the axis of the rotating shaft 11 is parallel to the horizontal ground; a turntable 2, the turntable 2 is coaxially installed on the rotating shaft 11; four blade structures 3, the four blade structures 3 are installed at intervals on a side of the turntable 2 away from the frame 1, the blade structure 3 includes a first connecting plate 31, a second connecting plate 32 and a third connecting plate 34, the first connecting plate 31 is parallel to the horizontal ground, the second connecting plate 32 is connected to a side edge of the first connecting plate 31 and is perpendicular to the first connecting plate 31, the The third connecting plate 34 is perpendicular to the horizontal ground, and both sides of the third connecting plate 34 are simultaneously connected to the first connecting plate 31 and the second connecting plate 32 on one side facing the turntable 2. The third connecting plate 34 is installed on the turntable 2; the four blade structures 3 are enclosed to form an open cross-shaped chamber 4; the motor 5 is installed on the frame 1, and the motor 5 is driven and connected to the rotating shaft 11; the plate 300 is horizontally sent from the side of the turntable 2 away from the frame 1 into the cross-shaped chamber 4, so that the blade structure 3 supports the plate 300, and the motor 5 drives the turntable 2 to rotate, so that the plate 300 is separated from the cross-shaped chamber 4 in the vertical direction. Figure 1 and Figure 2 shown.

[0028] like Figure 1As shown, in the initial state, the first connecting plate 31 is parallel to the horizontal ground, the second connecting plate 32 is perpendicular to the second connecting plate 32, and the third connecting plate 34 connects the first connecting plate 31 and the second connecting plate 32 and is installed on the turntable 2 to fix the blade structure 3 to the turntable 2. The first connecting plates 31 and the second connecting plates 32 of the four blade structures 3 are spatially enclosed to form an open cross-shaped chamber 4, wherein the first connecting plates 31 parallel to the horizontal ground are opposite to each other in pairs to form the horizontal part of the cross-shaped chamber 4, and the second connecting plates 32 perpendicular to the horizontal ground are opposite to each other in pairs to form the vertical part of the cross-shaped chamber 4. The horizontal part is connected to the vertical part, and the spacing between the two opposite first connecting plates 31 and the spacing between the two opposite second connecting plates 32 are slightly larger than the thickness of the plate 300 (or after multiple plates 300 are stacked) to allow the plate 300 to enter the cross-shaped chamber 4. In actual application, the plate 300 parallel to the horizontal ground enters the cross-shaped chamber 4 from the side facing away from the turntable 2 in the horizontal direction ( Figure 1 The arrow in the middle points to the feeding direction of the plate 300, which is also the axial direction of the rotating shaft 11 and the rotating disk 2. After the plate 300 enters the cross-shaped chamber 4, the lower surface of the plate 300 is supported by the blade structure 3 (such as Figure 1 As shown, supported by the first connecting plate 31), the upper surface of the plate 300 is limited by the blade structure 3 (as shown Figure 1As shown, the cross-shaped chamber 4 is limited by the first connecting plate 31, and because the cross-shaped chamber 4 is open, in the horizontal direction, even if the surface area (length and width) of the plate 300 is larger than the maximum cross-sectional area of ​​the cross-shaped chamber 4, the edge of the plate 300 is exposed outside the cross-shaped chamber 4, but as long as the center of gravity of the plate 300 is within the cross-shaped chamber 4, the plate 300 will be stably supported, so that the turning machine of the present invention can meet the use requirements of plates 300 of different specifications. In the prior art, if more than half of the plate 300 is exposed outside the blade, it is very easy to slip off the blade. The fundamental reason is that one side of the plate 300 is close to the root of the blade and is limited by the rotating shaft 11, making it impossible to move the center of gravity of the plate 300 to the surface of the blade. In the present application, the cross-shaped chamber 4 is open, and the plate 300 can be freely moved and placed in the cross-shaped chamber 4. The side of the plate 300 can protrude outside the cross-shaped chamber 4, and the center of gravity of the plate 300 is placed in the cross-shaped chamber 4 to stably support the plate 300. Preferably, if the surface area of ​​the plate 300 is larger than the maximum surface area of ​​the cross-shaped chamber 4, the center of gravity of the plate 300 can be placed in the middle of the cross-shaped chamber 4. At the same time, both ends of the plate 300 protrude from the outside of the cross-shaped chamber 4, and the surface areas of the parts of the plate 300 protruding from the outside of the cross-shaped chamber 4 are the same, so as to balance the weight of the plate 300. The motor 5 drives the turntable 2 to rotate ninety degrees, so that the plate 300 can slide from the vertical direction and gradually separate from the cross-shaped chamber 4. During the flipping process, the stacked plates 300 are limited by the blade structure 3 to achieve the technical effect of reducing or preventing the plates 300 from dispersing. After the motor 5 drives the turntable 2 to rotate ninety degrees, the motor 5 controls the turntable 2 to stop rotating, and another plate 300 is sent into the cross-shaped chamber 4. At this time, the lower surface of the plate 300 is supported by the second connecting plate 32, and the upper surface of the plate 300 is limited by the second connecting plate 32. This working principle can be seen from Figure 1 and Figure 2 The above is a concise conclusion and will not be further elaborated in this application. After the motor 5 drives the turntable 2 to rotate 90 degrees, the motor 5 controls the turntable 2 to stop rotating, causing the previous plate 300 to slide out of the cross-shaped chamber 4 and the next plate 300 to be fed into the cross-shaped chamber 4. This structural arrangement makes the feeding of the plates 300 highly consistent and improves the feeding and turning efficiency. In actual application, the motor 5 is mounted on the frame 1 via a base (not shown in the figure).

[0029] It is worth mentioning that in order to prevent the plate 300 from tilting upward or spreading during transportation, which would result in the plate 300 being blocked outside the cross-shaped chamber 4, the plate 300 is horizontally fed into the cross-shaped chamber 4 from the side of the turntable 2 that is away from the frame 1. Figure 1 As shown, the plate 300 enters the cross-shaped chamber 4 from the axial direction of the rotating shaft 11 , so as to shorten the conveying distance of the plate 300 before entering the cross-shaped chamber 4 .

[0030] In the technical scheme of the present application, in the height direction, the surface of the rotating disc 2 is provided with a plurality of first connecting holes (not marked in the figure), the surface of the third connecting plate 34 is provided with a second connecting hole 341 corresponding to the first connecting hole, and the third connecting plate 34 is connected to the first connecting hole and the second connecting hole 341 through a screw structure (not shown in the figure).

[0031] Through the adjustment of the installation position and height of the blade structure 3, the volume of the cross-shaped chamber 4 is adjusted to meet the feeding requirements of different thicknesses of the plate 300.

[0032] In the technical scheme of the present application, the side of the first connecting plate 31 and the second connecting plate 32 away from the rotating disc 2 is provided with a flange structure 33, and the flange structure 33 extends in the direction away from the cross-shaped chamber 4.

[0033] In actual application, the single board turnover machine 100 disclosed by the present application can be combined with the existing conveying belt, that is, the conveying belt horizontally conveys the plate 300, and the plate 300 horizontally enters the cross-shaped chamber 4. There may be a structural deformation problem in the stacked plate 300, and the plate 300 in a certain layer is upwardly buckled, which will cause the plate 300 to be blocked outside the cross-shaped chamber 4. To solve the above problem, as shown in the figure, Figure 1 In the initial state, the flange structure 33 of the upper first connecting plate 31 is upwardly turned, and the flange structure 33 of the lower first connecting plate 31 is downwardly turned to form a large flared structure. If the plate 300 is upwardly buckled, the plate 300 will be gradually pressed down when it touches the flange structure 33 to guide it into the cross-shaped chamber 4.

[0034] In the technical scheme of the present application, the blade structure 3 further comprises a fourth connecting plate 35, and the two side edges of the fourth connecting plate 35 are connected to the side edges of the first connecting plate 31 and the second connecting plate 32 away from the rotating disc 2.

[0035] Through the above structure, the fourth connecting plate 35 is arranged in the feeding direction of the plate 300 to block the direct feeding of the plate 300 to the first connecting plate 31 (the second connecting plate 32).

[0036] In the technical scheme of the present application, the side of the blade structure 3 facing the cross-shaped chamber 4 is a smooth plane structure.

[0037] Through the above structure, the smooth plane structure is used to reduce the friction between the plates 300 and increase the flexibility of the plate 300 when sliding to prevent hindering the feeding of the next plate 300.

[0038] The present invention also proposes a plate processing production line 200, including the single plate turning machine 100. The specific structure of the single plate turning machine 100 refers to the above embodiment. Since the plate processing production line 200 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here. Among them, the plate processing production line 200 also includes a conveyor belt mechanism 201 and a plate transfer mechanism (not shown in the figure). The conveyor belt mechanism 201 is used to horizontally send the plate 300 from the side of the turntable 2 away from the frame 1 into the cross-shaped chamber 4, so that the blade structure 3 supports the plate 300, and the motor 5 drives the turntable 2 to rotate, so that the plate 300 is separated from the cross-shaped chamber 4 in the vertical direction, and the plate 300 falls vertically into the plate transfer mechanism. As Figure 3 shown.

[0039] In practical applications, the function of the plate transfer mechanism is to allow the plate 300 to be placed vertically even when it is dropped vertically into the plate transfer mechanism. The specific structure generally includes a transfer vehicle, which is equipped with a transfer chamber with an open top and a frame mounted thereon. The frame is welded with a plurality of mutually spaced and parallel steel bars. During the falling process, the plate 300 passes between two adjacent steel bars, and the lower side of the plate 300 falls to the bottom of the transfer chamber, while the upper side of the plate 300 overlaps the steel bars. This type of transfer structure is prior art and will not be described in detail herein.

[0040] In the technical solution of the present invention, the conveyor belt mechanism 201 includes an upper conveyor belt 201-A and a lower conveyor belt 201-B. The lower conveyor belt 201-B supports the plate 300, and the upper conveyor belt 201-A is located above the plate 300 and is in close contact with the surface of the plate 300. Of course, the conveyor belt mechanism 201 can be installed on a frame.

[0041] In order to ensure that the surface of the overall structure is flat after the plates 300 are stacked, and to prevent the deformation of the structure of a certain layer of plates 300 from causing the plates 300 of other layers to warp upward and affect the feeding, in order to solve the above problems, the present application uses an upper and lower conveyor belt structure to convey the overall structure of the stacked plates 300, and at the same time the upper conveyor belt 201-A limits the overall structure, that is, it approaches the plates 300, so that the plates 300 are close to each other, ensuring that the plates 300 smoothly enter the cross-shaped chamber 4.

[0042] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention description and drawings under the inventive concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
