Description

Technical Field

[0001] The invention relates to the technical field of rock wool production, and in particular to a rock wool lifting and steering device, system and method. Background Art

[0002] The rock wool steering device is a device that turns the stacked rock wool boards 90 degrees during the rock wool production process due to the limitations of the production layout. After the rock wool boards are stacked, the direction of entering the packaging machine is wrong. It has been widely used in the field of rock wool production.

[0003] The rock wool is cut longitudinally and transversely into the required specifications. After transverse cutting, the rock wool board moves forward in the direction of its length. After lamination, it enters the packaging machine. The laminated rock wool board also moves forward longitudinally along the length direction. However, the packaging width of the packaging machine is similar to the length of the product. The rock wool board needs to enter the packaging system transversely, so the rock wool board needs to be rotated 90° before entering the packaging system after lamination to maximize the packaging surface.

[0004] In view of the above problems, there are two existing solutions: one is to increase the size of the turning roller, and add a transverse conveying device before turning to increase the distance between the rock wool layers, so that two rows will not be crowded together during the turning process and cannot turn 90°, causing them to enter the packaging system at an angle. After adding the turning roller, the production line is not in a straight line, which not only increases the floor space but also gives people a feeling of being unsmooth; the other is to rotate the packaging machine and all subsequent equipment 90°, so that the entire production line presents an "L" shape, and it is necessary to add several more transverse conveying devices, which increases the cost and the floor space, and the visiting channel must also follow the equipment and is set in an "L" shape, which is not smooth as a whole. Summary of the invention

[0005] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a rock wool lifting and steering device, system and method. By arranging a criss-cross-shaped liftable and rotatable pallet frame in a roller group, when the rock wool board on the roller group moves onto the pallet frame, the rock wool board of the pallet frame is lifted up and driven to rotate 90°, so that the rock wool production line can be arranged along a straight line without occupying too much space, and the viewing channel can be arranged along the straight line accordingly, the entire production line operates smoothly, and the equipment cost can be reduced.

[0006] In order to achieve the above object, the present invention is implemented through the following technical solutions:

[0007] In a first aspect, a rock wool jacking and steering device comprises:

[0008] The support frame is in a well shape and can be raised and lowered between the roller groups;

[0013] As a further implementation method, four groups of detection photoelectric devices are evenly distributed along the circumference on the periphery of the large gear fixed shaft on the top surface of the lifting plate; a group of detection positioning blocks are provided at the bottom of the large gear, and by detecting the detection positioning blocks through the detection photoelectric devices, it is realized to control the pallet frame to rotate 90° each time.

[0014] As a further implementation method, the telescopic member fixing seat includes a bottom plate and an inverted U-shaped fixing seat, the inverted U-shaped fixing seat is fixed on the bottom plate, the telescopic member is fixed inside the inverted U-shaped fixing seat, and the output end of the telescopic member passes through the inverted U-shaped fixing seat and is connected to the lifting plate.

[0015] As a further implementation method, several sliders are provided on both sides of the inverted U-shaped fixing seat, and several vertical optical axes are correspondingly provided at the bottom of the lifting plate, and the optical axes pass through the sliders, and the lifting and guiding of the optical axes are realized through the sliders.

[0016] As a further implementation method, the pallet frame is a symmetric structure.

[0017] In the second aspect, a rock wool conveying system includes a rock wool jacking and turning device as described in any one of the above, and further includes a roller group. The roller group includes a long roller group and a short roller group. A cross-shaped accommodating space is formed by the short roller group, and the pallet frame is liftably arranged in the accommodating space. The long roller group and the short roller group are synchronously rotated through the cooperation of transmission gears and chains; the roller group is installed in a rectangular support frame.

[0018] As a further implementation method, both ends of the support frame are respectively arranged close to the first conveyor belt and the second conveyor belt, and a transmission detection photoelectric device is provided at the middle position of the long side of the support frame.

[0019] In the third aspect, a rock wool conveying method uses a rock wool system as described in any one of the above, and includes the following steps:

[0020] After being cut, the rock wool reaches the first conveyor belt and is sent to the roller group. When the roller group drives the rock wool to move onto the pallet rack body, after the transmission detection photoelectric pair shoots and detects the rock wool, after a set delay time, the roller group stops rotating, and the telescopic member drives the lifting plate to rise to lift the pallet rack body. Then, after the driving mechanism drives the pallet rack body to rotate 90°, the telescopic member drives the pallet rack body to fall, and the roller group acts again to convey the rock wool onto the second conveyor belt.

[0033] It should be noted that the following detailed descriptions are all exemplary and are intended to provide further explanations for the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those of ordinary skill in the technical field to which the present invention belongs.

[0034] Embodiment 1

[0035] In a typical implementation mode of the present invention, referring to Figures 1-3 as shown, a rock wool lifting and turning device includes a pallet frame body 1, a lifting plate 6, a driving mechanism, and a telescopic member fixed seat.

[0036] The pallet frame body 1 is in a cross shape and is arranged in the roller group in a liftable manner; a driving mechanism is provided on the lifting plate, and the output end of the driving mechanism is connected to the center position of the pallet frame body 1 through a large gear fixed shaft 2 to realize that the pallet frame body 1 rotates 90° each time; a telescopic member is provided on the telescopic member fixed seat, and the output end of the telescopic member is connected to the lifting plate 6 to drive the lifting plate 6 to lift and lower.

[0037] As Figure 2 shown, the pallet frame body 1 is formed into a cross shape by welding multiple square tubes and forms a square opening in the middle, and is closed at the square opening in the middle through a connecting steel plate. The steel plate is a square plate 111 and is welded to the square tubes of the pallet frame body 1 to form an integral structure. The square plate 111 is provided with fixing holes connected to the top end of the large gear fixed shaft. There are multiple fixing holes, which are located at the center position of the square plate 111. The top end of the large gear fixed shaft 2 is fixedly connected through bolts passing through the fixing holes, realizing the fixed connection between the pallet frame body 1 and the top end of the large gear fixed shaft.

[0038] As Figure 1 shown, the lifting plate 6 is arranged below the pallet frame body 1 and is parallel to the pallet frame body 1. A driving mechanism is provided on the lifting plate 6, and a large gear fixed shaft 2 is vertically provided on the lifting plate 6. The bottom end of the large gear fixed shaft 2 is rotationally matched with the lifting plate.

[0039] The drive mechanism includes a reduction motor 14 fixed on the lifting plate 6, and a pinion is provided at the output end of the reduction motor 14. As Figure 1 shown, the reduction motor 14 is fixed below the lifting plate 6 near the end position, and the output end of the reduction motor 14 is a pinion fixed shaft 13. The top end of the pinion fixed shaft 13 penetrates the lifting plate 6 upward and is provided with a pinion 12.

[0040] A pinion baffle 11 is provided at the top end of the pinion fixed shaft 13. The pinion baffle 11 is located above the pinion 12 and is used to prevent the pinion 12 from running off track.

[0041] As Figure 1 shown, a large gear 3 is provided on the circumferential side of the middle position of the large gear fixed shaft 2. The large gear 3 meshes with the pinion 12. The reduction motor 14 drives the pinion 12 to rotate through the pinion fixed shaft 13, and then the large gear 3 rotates, so that the large gear fixed shaft 2 drives the pallet rack 1 to rotate.

[0042] The purpose of this embodiment is to realize a 90° turn of the rock wool. Therefore, the pallet rack 1 supporting the rock wool needs to rotate 90° each time. In order to realize that the pallet rack 1 rotates 90° each time, four groups of detection photoelectric sensors 5 are evenly distributed along the circumference on the circumferential side of the large gear fixed shaft 2 on the top surface of the lifting plate 6; a group of detection positioning blocks 4 are provided at the bottom of the large gear 3, and the detection positioning blocks 4 are adapted to the height of the four groups of detection photoelectric sensors 5.

[0043] The detection photoelectric sensor 5 is a light point sensor, which is installed on the top surface of the lifting plate 6 through an L-shaped bracket. The four groups of detection photoelectric sensors 5 are arranged on the same circumference and are spaced 90°. By detecting the detection positioning block 4 through the detection photoelectric sensor 5, it can be realized to control the pallet rack to rotate 90° each time. As the reduction motor 14 drives the large gear to rotate, when the detection positioning block 4 fixed on the large gear 3 rotates and triggers the next detection photoelectric sensor 5, the detection photoelectric sensor 5 sends a signal to the controller, and the controller controls the reduction motor 14 to stop moving, which can ensure that each time the reduction motor 14 operates, the rock wool board on the pallet rack 1 can rotate 90°.

[0044] In order to lift the rock wool board from the roller group, it is necessary to realize the lifting of the lifting plate 6, and then drive the pallet rack 1 to lift through the large gear fixed shaft 2. Specifically, a telescopic member is provided on the telescopic member fixed seat, and the output end of the telescopic member is connected to the lifting plate to drive the lifting plate 6 to lift.

[0045] As Figure 1 and Figure 3 shown, the telescopic member fixed seat is a cylinder fixed seat 15. The cylinder fixed seat 15 includes a bottom plate and an inverted U-shaped fixed seat connected as a whole. The inverted U-shaped fixed seat is fixed on the bottom plate, as Figure 1 shown.

[0046] The telescopic member uses a cylinder 10, which is fixed inside an inverted U-shaped fixing seat and below the top plate between the two side plates of the inverted U-shaped fixing seat. The output end of the cylinder 10 passes upward through the top plate of the inverted U-shaped fixing seat and is connected to the lifting plate 6.

[0047] Specifically, when the cylinder 10 operates, the output end of the cylinder 10 jacks up the lifting plate 6 upward. The lifting plate 6 drives the linkage structures such as the large gear fixed shaft 2, the pallet frame body 1, the detection photoelectric 5, and the reduction motor 14 to rise synchronously, so that the rock wool board on the pallet frame body 1 is jacked up to a height higher than that of the roller group 103. At this time, the roller group 103 will not drive the rock wool to transmit. Then the reduction motor 14 operates to realize the rotation of the pallet frame body 1 driving the rock wool board by 90°, achieving the jacking and turning work of the rock wool board.

[0048] To ensure the stability of the lifting and lowering of the lifting plate 6, as Figure 1 and Figure 3 shown, several sliders are provided on the outer sides of the two side plates of the inverted U-shaped fixing seat. Specifically, two sliders 9 are provided at the same height of each side plate. The sliders 9 are fixedly connected to the side plates of the inverted U-shaped fixing seat.

[0049] Correspondingly, four vertical optical axes 8 are provided at the bottom of the lifting plate 6. The top ends of the optical axes 8 are fixedly connected to the bottom surface of the lifting plate through the optical axis fixing seat 7. The optical axes 8 pass downward through the sliders, and the lifting and lowering guidance of the optical axes is realized through the sliders 9, so as to ensure that the lifting plate 6 can be lifted and lowered stably in the vertical direction.

[0050] It can be understood that the length of the optical axis 8 is less than the distance between the lifting plate 6 and the bottom plate when it falls.

[0051] As Figure 2 and Figure 4 shown, the pallet frame body 1 in this example is a symmetric structure and is set as a grid structure. The purpose is that it can be arranged between the roller groups. Thus, when the pallet frame body 1 rises, the roller group 103 cannot continue to drive the rock wool board. When the pallet frame body 1 falls, its height is slightly lower than that of the roller group 103, so that the roller group 103 can continue to drive and drive the rock wool board to be transported horizontally.

[0052] In the rock wool jacking and turning device of this embodiment, by arranging the grid-shaped liftable and rotatable pallet frame body 1 inside the roller group, when the rock wool board on the roller group moves onto the pallet frame body 1, the pallet frame body 1 jacks up the rock wool board and drives it to rotate by 90°. In this way, without occupying too much space, the rock wool production line can be arranged in a straight line, the viewing passage can be arranged correspondingly in a straight line, the whole production line works smoothly, and the equipment cost can be reduced.

[0053] Embodiment 2

[0054] In a typical implementation manner of the present invention, referring to Figures 1-4As shown in the figure, a rock wool conveying system includes a rock wool lifting and turning device described in Embodiment 1, and further includes a roller group 103.

[0055] As Figure 4 shown in the figure, the roller group is installed in a support frame 101 with a rectangular shape. The roller group 103 includes a long roller group and a short roller group. A cross-shaped accommodation space is formed by the short roller group, so that the pallet frame body 1 can be arranged at the accommodation space in a liftable manner.

[0056] As Figure 4 shown in the figure, inside the support frame 101 corresponding to the cross-shaped accommodation space, the cross-shaped accommodation space is formed by arranging eight groups of short roller groups 103 at intervals. Each short roller group includes three short rollers. The three short rollers in the same longitudinal direction on the left and right sides are connected by a connecting shaft 106 and can rotate synchronously. The short rollers at one ends of the middle two groups of short roller groups in the same longitudinal direction away from the long sides of the support frame are connected into one body by a connecting shaft 106, so that the short rollers in the same longitudinal direction can rotate synchronously under the action of the connecting shaft. The connecting shaft passes through the internal support beam 105 and is rotationally matched with the internal support beam 105.

[0057] As Figure 5 shown in the figure, there are two internal support beams arranged horizontally. The internal support beams can be fixed to the sides of the support frame as a whole through structures such as connecting frames. The connecting frame is lower than the internal support beam and is not shown in the figure.

[0058] As Figure 4 shown in the figure, the long roller group includes a plurality of long rollers. The long rollers are not provided with connecting shafts and are directly rotationally matched at the long sides of the support frame at both ends.

[0059] Gears are provided at one ends of the long rollers and the short rollers close to the long sides of the support frame. The gears and chains are matched at the same long side, and a driving gear is configured. When the driving gear rotates, the rollers on the roller group can rotate, realizing the synchronous rotation of the long roller group and the short roller group through the cooperation of transmission gears and chains. Structures such as gears, chains, and driving gears are set as prior arts.

[0060] It can be understood that the thickness of the pallet frame body 1 in this embodiment is less than the cross-sectional radius of the long rollers and the short rollers, so that when the pallet frame body 1 descends to be close to the top surface of the internal support beam 105, at this time, the highest point of the roller group is higher than the top surface of the bracket body 1. After the pallet frame body 1 descends, the roller group can drive the rock wool board on it to be transmitted horizontally.

[0061] Both ends of the support frame are respectively close to the conveyor belt 104, as Figure 4As shown, there are a first conveyor belt and a second conveyor belt respectively. In the middle position of the long side of the support frame, there are two transmission detection photoelectric sensors 102, which are also correspondingly arranged at the horizontal middle position of the pallet rack 1. The transmission detection photoelectric sensors 102 are arranged opposite to each other to detect the rock wool board on the pallet rack, so as to detect whether the rock wool board has moved onto the pallet rack 1.

[0062] Embodiment 3

[0063] In a typical implementation manner of the present invention, refer to Figures 1-4 As shown, a rock wool conveying method, using a rock wool system described in Embodiment 2, includes the following steps:

[0064] After being cut, the rock wool reaches the first conveyor belt and is sent to the roller group under the action of the first conveyor belt. When the rock wool board is conveyed to the center position of the corresponding pallet rack 1 by the roller group, after the transmission detection photoelectric sensors 102 detect the rock wool board by opposite shooting, they send signals to the controller. The controller delays for two seconds, controls the roller group to stop driving, and then controls the cylinder 10 to lift the rock wool board using the pallet rack 1.

[0065] The purpose of delaying for two seconds is to ensure that after the delay, the rock wool board can move to a position coaxial with the pallet rack 1 under the driving action of the roller group. It can also be understood that the roller group drives the rock wool board to move horizontally for two seconds, and the distance the rock wool board moves is close to half of the length of the pallet rack 1.

[0066] After the controller controls the cylinder 10 to lift the rock wool board through the pallet rack 1, the controller controls the reduction motor to act. Under the cooperative action of the detection photoelectric sensor 5 and the detection positioning block 4, when the detection positioning block fixed on the large gear rotates 90° to the next position and is detected by the detection photoelectric sensor, the detection photoelectric sensor 5 emits a signal to trigger the motor to decelerate and stop. At this time, the rock wool board completes a 90° turn. Then the controller controls the cylinder to fall back and its linkage parts to return to the original position, and the rock wool board falls back onto the roller group. The roller group starts to convey the rock wool board to the next link.

[0067] In other examples, a detection photoelectric sensor is correspondingly arranged at the high position of the lifting plate, so that when the lifting plate rises to the high position, the detection photoelectric sensor can recognize it and emit a signal, and then the controller can control the reduction motor to act. In this example, this detection photoelectric sensor is not set, and the turning of the rock wool board is realized only by setting the stroke of the cylinder.

[0068] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
