Description

Technical Field

[0001] The invention relates to the technical field of prefabricated board production technology, and in particular to a high-efficiency prefabricated board production technology. Background Art

[0002] Prefabricated panels are usually coated with anti-cracking mortar, mesh cloth, etc. on one or both sides of the substrate, and then cut and stacked after curing and forming. In the traditional production process, the prefabricated panels are laid along the assembly line at a fast speed. Although the cutting process takes some more time, it can be synchronized with the assembly line by arranging multiple cutting stations in parallel. At present, the biggest impact on the overall production speed is how to quickly transfer the substrate surface to the curing station when the substrate is in a semi-dry and semi-wet state after laying, and when the vacuum suction cup cannot be used to grab the material.

[0003] The traditional transfer method is to use a lifting method, hook the bottom surface of the substrate and transfer it to the front of the elevator, but this method is time-consuming, labor-intensive and inefficient.

[0004] For prefabricated panels with double-sided paving, the production process is more complicated. For example, the patent number is CN201520804684.0, and the name is a new type of insulation board production line. It provides a production line for double-sided coating of substrates. It is necessary to build two drying rooms, one in front and one behind, and two sets of coating devices. The storage barrels transport the slurry to the two sets of coating devices respectively. There are many duplicate equipments and the space is large.

[0005] In addition, when the prefabricated panels are transferred to the curing warehouse, they are usually transported by elevators. The traditional transportation method is that the lifting mechanism lifts the panel to the designated layer, then the lifting mechanism falls back to the bottom, and then lifts another panel to the designated layer, and repeats this process, which is inefficient. The lower layer can still adapt to the speed of the assembly line, but when transporting to the higher layer, the assembly line has to stop running. Because of this, the height of the curing warehouse in the workshop cannot be designed too high.

[0006] Since the curing warehouse is not high to begin with, the prefabricated panels transported by the assembly line are higher than the ground, which makes the bottom space of the curing warehouse unusable and causes waste. Summary of the invention

[0007] In order to solve the technical problems existing in the above-mentioned background technology, the present invention provides a high-efficiency production process of prefabricated panels.

[0008] The technical solution of the present invention is as follows:

[0009] A high-efficiency production process for prefabricated panels comprises the following steps:

[0010] S1, transport the substrate along the transmission line to the bottom of the composite unloading unit, and lay the material on one side;

[0011] S2, transfer the substrate from the transmission line to the board entry station, and transfer the substrate to the storage elevator after reversing the direction;

[0012] S3, lift the prefabricated panels to a specified height through the storage elevator and push them into the three-dimensional warehouse;

[0013] The storage elevator includes an outer frame, the bottom of which is in contact with a bottom track through a sliding wheel, and the bottom track is arranged perpendicular to the transmission line;

[0014] An upper plate waiting bracket is provided at the lower part of the outer frame, which is used to dock with the plate feeding station. The length direction of the upper plate waiting bracket is perpendicular to the bottom track, and a transmission component is provided along the length direction thereof;

[0015] A set of upper plate transmission mechanisms are respectively arranged on both sides of the upper plate material waiting bracket on the outer frame, and the upper plate transmission mechanism includes two first chain transmission assemblies arranged front and back oppositely, and a plurality of support plates are arranged at intervals on the chain. The support plates of the two sets of upper plate transmission mechanisms are arranged oppositely at the inner side, and the spacing is greater than the width of the upper plate material waiting bracket and less than the width of the base plate;

[0016] The inner sides of the two sets of upper plate transmission mechanisms are connected with push plate mechanisms that can move up and down, and the lower sides of the push plate mechanisms are connected with push plates that can move forward and backward;

[0017] The specific steps are:

[0018] S31, the upper plate waiting bracket receives the prefabricated plate transmitted from the plate feeding station;

[0019] S32, the support plates of the two sets of upper plate transmission mechanisms lift the two sides of the bottom end of the substrate and transmit it upward for T1 time;

[0020] S33, after waiting for an interval of time T0, the board feeding station transfers the next prefabricated board to the upper board waiting bracket, and the lower support plate of the upper board transmission mechanism moves upward to lift and transfer the prefabricated board upward;

[0021] S34, within time T2, the push plate mechanism pushes the prefabricated plate at the same height as the push plate along the support plate to the three-dimensional warehouse and returns it to its original position;

[0022] T0=T1+T2;

[0023] S4, the prefabricated panels are maintained in a three-dimensional warehouse. The three-dimensional warehouse is arranged parallel to the transmission line, and the conveying speed is determined according to the length of the three-dimensional warehouse and the required maintenance time of the prefabricated panels;

[0024] S5. The prefabricated panels are transported out of the three-dimensional warehouse by the outgoing elevator and transferred to the outgoing panel station. The outgoing elevator has the same structure as the incoming elevator except that it does not have a panel pushing mechanism. It is symmetrically slidably connected to the two ends of the three-dimensional warehouse with the incoming elevator.

[0025] S6. Send the prefabricated panels that have been cured at the panel discharging station to the downstream cutting station, stacking station, or carry out the paving work on the other side.

[0026] The present invention improves the structure of the elevator, so that the prefabricated panels can enter the stereoscopic warehouse for curing at equal speed intervals, so that the height of the stereoscopic warehouse can be made as equal to the workshop height as possible, thereby making full use of the workshop resources.

[0027] In step S6, when the material is laid on the other side of the substrate, a plate turning station is set upstream of the composite unloading unit on the transmission line, one end of the plate discharge station is close to the plate placement position at the source of the transmission line, and a turnover plate stacking machine is set. The specific steps are as follows:

[0028] S61, transferring the prefabricated panels on the panel discharging station to the transmission line through the turnover panel stacking machine;

[0029] S62, the prefabricated board is turned over through the board turning station so that the other side of the base plate faces upward;

[0030] S63, the prefabricated panels repeatedly pass through the composite unloading unit, the panel feeding station, the storage elevator, the three-dimensional warehouse, and the storage elevator to reach the panel discharging station, and then the prefabricated panels are sent to the cutting station and the stacking station.

[0031] When both sides of the base plate need to be paved, the first time the prefabricated plate passes through the three-dimensional warehouse for curing, it does not need to be cured for too long. It only needs to ensure that the paving material on the base plate does not fall off after turning over. At the same time, the thickness of the first paving material is less than the thickness of the paving material after turning over, which can better prevent the first paving material on the base plate from falling off the base plate due to gravity.

[0032] As another inventive point of the present invention, the transmission line and the stereoscopic warehouse are installed on the ground, the height of the base plate on the transmission line is higher than the height of the lowest maintenance line of the stereoscopic warehouse, the bottom track is installed under the ground, the upper surface height of the upper plate waiting bracket is lower than the height of the lowest maintenance line of the stereoscopic warehouse, and the board feeding station can lower the height of the prefabricated board transported on the transmission line and change the transmission direction before transmitting it to the upper plate waiting bracket.

[0033] In this way, through the design of variable height of the production line, the overall space of the three-dimensional warehouse can be effectively utilized, and the bottom space of the three-dimensional warehouse will not be wasted.

[0034] Specifically, the board feeding station includes a rollover transfer assembly, a board feeding transfer assembly and a board feeding material support;

[0035] The rollover transfer assembly is connected to the downstream of the transmission line through a free roller, the board feeding transfer assembly is arranged perpendicular to the transmission line on one side of the rollover transfer assembly, and the board feeding material waiting bracket includes a plurality of brackets arranged side by side between the bottom track and the board feeding transfer assembly;

[0036] The adjacent ends of the rollover transfer assembly and the board entry transfer assembly are both provided with lifting devices;

[0037] Step S2 is specifically as follows:

[0038] S21, the substrate enters the rollover transfer assembly horizontally via a free roller;

[0039] S22, the side rollover transfer assembly is lowered near one end of the board entry transfer assembly, and the board entry transfer assembly is raised near one end of the side rollover transfer assembly until the inclined surfaces of the two overlap;

[0040] S23, the substrate changes its moving direction by 90 degrees and slides into the board loading and transferring assembly from the side along the inclined surface;

[0041] S24, the board loading and transferring assembly transports the substrate to the designated board loading and waiting bracket;

[0042] S25, the substrate changes its moving direction by 90 degrees and enters the board feeding and waiting bracket, and is then transferred to the storage elevator.

[0043] As a preferred embodiment, the transmission line, the stereoscopic warehouse and the cutting station are parallel to each other and arranged in an S shape, which can make the entire assembly line very compact and make full use of the workshop space.

[0044] When both the elevator and the warehouse are high-rise, upper tracks are connected to the upper parts of both ends of the warehouse. The upper tracks are arranged parallel to the bottom tracks. Upper anti-tilt mechanisms are provided on the upper parts of the elevators for entry and exit. The upper anti-tilt mechanisms are slidably connected to the upper tracks to ensure the safety of the elevators during operation and prevent tipping.

[0045] In addition, the transmission line includes an upstream conveyor roller and a downstream belt roller, the conveyor roller speed is greater than the belt roller speed, the flipping station is located on the conveyor roller, and the composite unloading unit is located above the belt roller.

[0046] A fixed-length roller is arranged on the belt roller downstream of the composite unloading unit for cutting the mesh cloth into fixed length.

[0047] The board discharging station is installed under the ground, including the board discharging and transferring assembly and the board loading and stacking machine;

[0048] When the prefabricated board is laid on one side, the board delivery and transfer assembly will go down after docking the prefabricated board transferred by the outbound elevator, and then be transferred to the cutting station through the loading and stacking machine;

[0049] When the prefabricated panels are double-sided, the first round of the panel transfer assembly will go up after docking with the prefabricated panels transmitted by the outbound elevator, and will be transferred to the transmission line through the turnover stacking machine. At this time, the transmission line will no longer put empty base boards until the turnover stacking machine transfers all the prefabricated panels with single-sided material to the transmission line. Then the second round of the panel transfer assembly will go down after docking with the prefabricated panels transmitted by the elevator, and will be transferred to the cutting station through the loading stacking machine.

[0050] Through the above design, the efficient production process of prefabricated panels of the present invention is centered on maximizing the use of workshop resources and maximizing the number of prefabricated panels that can be cured simultaneously without affecting the normal speed of the production line. First, through the improvement of the elevator structure, the prefabricated panels can enter the stereoscopic warehouse for curing at equal speed intervals, so that the height of the stereoscopic warehouse can be made as equal to the workshop height as possible, thereby making full use of workshop resources.

[0051] Then the transmission line and the stereoscopic warehouse are installed on the ground. The height of the substrate on the transmission line is higher than the height of the bottom maintenance line of the stereoscopic warehouse. The bottom track is installed under the ground. The upper surface height of the upper plate waiting bracket is lower than the height of the bottom maintenance line of the stereoscopic warehouse. The board feeding station can lower the height of the prefabricated board transported on the transmission line and change the transmission direction before transmitting it to the upper plate waiting bracket. In this way, through the design of variable height of the production line, the overall space of the stereoscopic warehouse can be effectively utilized, and the bottom space of the stereoscopic warehouse will not be wasted.

DETAILED DESCRIPTION

[0070] Example 1

[0071] See also Figure 1 Here we introduce an efficient production process for prefabricated panels with single-sided paving, including the following steps:

[0072] S1, transport the substrate along the transmission line 1 to the bottom of the composite unloading unit 2, and lay the material on one side;

[0073] The composite unloading unit 2 can perform operations such as automatic proportioning, automatic unloading, automatic spreading, etc. of multiple types of mortars. In addition, an automatic mesh cloth laying mechanism is also provided.

[0074] The transmission line 1 is arranged in a straight line, including an upstream conveyor roller 11 and a downstream belt roller 12. The speed of the conveyor roller 11 is greater than that of the belt roller 12, and the composite unloading unit 2 is located above the belt roller 12. The material laying process is basically completed by entering the bottom of the composite unloading unit 2 smoothly. A conveyor chain plate 15 is provided at the initial end of the conveyor roller 11 to transfer the substrate to the conveyor roller 11. Since the transfer of the substrate requires some extra time, the conveyor roller 11 needs to accelerate the transfer of the substrate to the belt roller 12 to eliminate this time difference.

[0075] A fixed-length roller 13 is provided on the belt roller 12 downstream of the composite unloading unit 2 for cutting the mesh cloth to a fixed length. After cutting, the mesh cloth is also caught up with the substrate in front through a section of conveyor roller structure.

[0076] S2, transfer the substrate from the transmission line 1 to the board feeding station 3, and transfer the substrate to the storage elevator 4 after changing the direction;

[0077] In order to reduce the floor space of the production line, the substrate in step S2 enters the storage elevator after two consecutive 90-degree angle changes, which is equivalent to the substrate turning 180 degrees and returning to the maintenance station.

[0078] S3, lift the prefabricated panels to a specified height through the storage lift 4 and push them into the three-dimensional warehouse 5;

[0079] The storage elevator 4 includes an outer frame 41, the bottom of the outer frame 41 is in contact with a bottom track 42 through a sliding wheel, the bottom track 42 is arranged perpendicular to the transmission line 1, and the conveying direction of the prefabricated board is parallel to the direction of the transmission line 1;

[0080] The lower part of the outer frame 41 is provided with an upper plate material support 44, see Figure 4-Figure 6 As shown, it is used for docking the board feeding station 3, the length direction of the upper board material support 44 is perpendicular to the bottom track 42, and a transmission component is arranged along the length direction thereof, and the transmission component can be a belt drive to smoothly transmit the prefabricated parts;

[0081] A set of upper plate transmission mechanisms 45 are respectively arranged on both sides of the upper plate material support 44 on the outer frame 41, see Figure 4 The upper plate transmission mechanism 45 includes two first chain transmission assemblies 451 arranged front and rear oppositely, and a plurality of support plates 452 are arranged at intervals on the chain, and the support plates 452 are horizontally connected to the chains of the two first chain transmission assemblies 451 front and rear. The support plates 452 on the inner side of the two sets of upper plate transmission mechanisms 45 are arranged oppositely, and the spacing is greater than the width of the upper plate material support bracket 44 and less than the width of the substrate;

[0082] The inner sides of the two sets of upper plate transmission mechanisms 45 are connected to push plate mechanisms 46 that can move up and down, see Figure 7 As shown, a push plate 462 that moves forward and backward is connected below the push plate mechanism 46;

[0083] The specific steps are:

[0084] S31, the upper plate waiting support 44 receives the prefabricated plate transmitted from the plate feeding station 3, at this time, the push plate mechanism 46 reaches the predetermined position, and the push plate 462 is located outside the outer frame 41;

[0085] S32, the support plates 452 of the two sets of upper plate transmission mechanisms 45 lift the two sides of the bottom end of the substrate and transmit it upward for T1 time;

[0086] S33, after waiting for an interval of time T0, the board feeding station 3 transfers the next prefabricated board to the upper board waiting bracket 44, and the lower support plate 452 of the upper board transmission mechanism 45 moves upward to lift and transfer the prefabricated board upward;

[0087] S34, the push plate mechanism 46 pushes the prefabricated plate at the same height as the push plate 462 along the support plate 452 to the three-dimensional warehouse 5 within the time T2, and returns to the original position;

[0088] T0=T1+T2;

[0089] In this way, no matter how high the prefabricated panels need to be transported in the warehouse, only one panel needs to be transported at an interval of T0, at a uniform and stable speed, and is not affected by the height.

[0090] S4, the stereoscopic warehouse 5 maintains the prefabricated panels. The stereoscopic warehouse 5 is arranged parallel to the transmission line 1. The conveying speed is determined according to the length of the stereoscopic warehouse 5 and the required maintenance time of the prefabricated panels.

[0091] See also Figure 1 As shown, the stereoscopic warehouse 5 is designed with multiple rows, which are arranged in parallel, and two rows are fixedly connected as a group to reduce the floor space, and a maintenance passage is left between two adjacent groups.

[0092] S5, the prefabricated panels are transported out of the three-dimensional warehouse 5 by the outgoing elevator 6 and transferred to the panel-outgoing station 7. The outgoing elevator 6 has the same structure as the incoming elevator 4 except that it does not have the panel-pushing mechanism 46. It is symmetrically slidably connected to the bottom rails 42 at both ends of the three-dimensional warehouse 5 with the incoming elevator 4;

[0093] The specific steps for transferring prefabricated panels are:

[0094] S51, the upper plate transmission mechanism 45 stops moving, and makes the current curing line outlet position face the support plate 452, and then transfers a prefabricated plate to the support plate 452;

[0095] At the same time, the upper plate waiting support 44 transfers the prefabricated plate placed thereon to the plate discharging station 7;

[0096] S52, the upper plate transmission mechanism 45 moves downward to the height of the spacing between the two support plates 452, the support plate above the upper plate waiting bracket 44 moves downward, and the prefabricated plate supported thereon is placed on the transmission part of the upper plate waiting bracket 44;

[0097] S6, sending the prefabricated panels cured at the panel discharging station 7 to the downstream cutting station 8 and stacking station 9.

[0098] In this embodiment, the transmission line 1, the three-dimensional warehouse 5 and the cutting station 8 are parallel to each other and arranged in an S shape, so that the whole assembly line becomes very compact and the workshop space is fully utilized.

[0099] The present invention improves the structure of the elevator, so that the prefabricated panels can enter the stereoscopic warehouse 5 for curing and exit the warehouse at equal speed intervals, so that the height of the stereoscopic warehouse 5 can be made as equal to the workshop height as possible, making full use of the workshop resources.

[0100] Example 2

[0101] In order to further utilize the workshop space and avoid the problem of wasting the bottom space of the stereoscopic warehouse. In this embodiment, the transmission line 1 and the stereoscopic warehouse 5 are installed on the ground, the height of the upper substrate of the transmission line 1 is higher than the height of the bottom maintenance line of the stereoscopic warehouse 5, the bottom track 42 is installed under the ground, the upper surface height of the upper plate waiting bracket 44 is lower than the height of the bottom maintenance line of the stereoscopic warehouse 5, the board feeding station 3 can lower the height of the prefabricated board transported on the transmission line 1 and change the transmission direction before transmitting it to the upper plate waiting bracket 44, and the board discharging station 7 is located under the ground, and its height is flush with the height of the upper plate waiting bracket 44 at the bottom of the warehouse discharging elevator 6.

[0102] In this way, through the design of variable height of the production line, the overall space of the stereoscopic warehouse 5 can be effectively utilized, and the bottom space of the stereoscopic warehouse 5 will not be wasted.

[0103] Specifically, the board feeding station 3 includes a rollover transfer assembly 31, a board feeding transfer assembly 32 and a board feeding material support 33;

[0104] The rollover transfer assembly 31 is connected to the downstream of the transmission line 1 through the free roller 14. The board entry transfer assembly 32 is arranged perpendicular to the transmission line 1 on one side of the rollover transfer assembly 31. A plurality of board entry material waiting brackets 33 can be provided according to the total width of the three-dimensional warehouse 5. The board entry material waiting brackets 33 include a plurality of brackets, which are arranged side by side between the bottom track 42 and the board entry transfer assembly 32, and are located opposite to each entrance of the three-dimensional warehouse.

[0105] The adjacent ends of the rollover transfer assembly 31 and the plate entry transfer assembly 32 are both provided with lifting devices, such as lifting cylinders;

[0106] Step S2 is specifically as follows:

[0107] S21, the substrate enters the rollover transfer assembly 31 horizontally via the free roller 14;

[0108] S22, the side rollover transfer assembly 31 is lowered near one end of the board entry transfer assembly 32, and the board entry transfer assembly 32 is raised near one end of the side rollover transfer assembly 31, until the inclined surfaces of the two overlap;

[0109] S23, the substrate changes its moving direction by 90 degrees and slides into the board loading and unloading assembly 32 from the side along the inclined surface;

[0110] S24, the board feeding transfer assembly 32 transports the substrate to the designated board feeding waiting bracket 33;

[0111] S25, the substrate changes its moving direction by 90 degrees and enters the board feeding and waiting support 33, and is then transferred to the storage elevator 4.

[0112] The board discharging station 7 includes a board discharging transfer assembly 71 and a loading and stacking machine 72. The height of the board discharging transfer assembly 71 is flush with the height of the upper board waiting bracket 44 at the bottom of the warehouse discharging elevator 6. The number and length are determined according to the total width of the three-dimensional warehouse 5.

[0113] The cutting station 8 is located above the ground, and a loading and stacking machine 72 is provided at the position where the board discharging and transferring assembly 71 transfers the prefabricated boards to the cutting station.

[0114] Since the present invention realizes uninterrupted and efficient transmission of the substrate, the cutting time of the cutting station 8 for a single prefabricated plate is relatively long, so a plurality of parallel cutting stations are provided to meet the requirements of the production line.

[0115] Example 3

[0116] See also Figure 2 ,This scheme introduces an efficient production process for prefabricated panels with double-sided paving.

[0117] The single-sided paving work is carried out first, and the steps are the same as those in Example 1.

[0118] In step S6, when the material laying work is carried out on the other side of the substrate, a plate turning station 10 is set upstream of the composite unloading unit 2 on the transmission line 1, and the plate turning station 10 is located on the conveying roller 11. One end of the plate discharge station 7 is close to the plate placing position at the source of the transmission line 1, and a turnover plate stacking machine 16 is set. The specific steps are as follows:

[0119] S61, transferring the prefabricated board on the board discharging station 7 to the transmission line 1 through the turnover stacking machine 16;

[0120] S62, the prefabricated board is turned over through the board turning station 10 so that the other side of the base plate faces upward;

[0121] S63, the prefabricated board repeatedly passes through the composite unloading unit 2, the board feeding station 3, the storage elevator 4, the three-dimensional warehouse 5, the storage elevator 6 to reach the board outgoing station 7, and then the prefabricated board is sent to the cutting station 8 and the stacking station 9.

[0122] When both sides of the substrate need to be paved, the first time the prefabricated board passes through the stereoscopic warehouse 5 for curing, it does not need to be cured for too long, and it is only necessary to ensure that the paving materials on the substrate do not fall off after turning over. At the same time, the thickness of the first paving material is less than the thickness of the paving material after turning over, which can better prevent the first paving material on the substrate from falling off the substrate due to gravity.

[0123] The panel turning station 10 is stationary when only one side of the prefabricated panel is paved.

[0124] The two ends of the board discharging station 7 are respectively close to the starting end of the transmission line 1 and the starting end of the cutting station 8. After the single-side paving of the substrate is completed, it is decided whether the prefabricated board is transferred to the transmission line 1 or the cutting station 8 according to whether the other side needs to be paved.

[0125] When the prefabricated board is single-sided, the board transfer assembly 71 docks the prefabricated board transferred by the outbound elevator 6 and then moves downward, and is transferred to the cutting station 8 via the loading and stacking machine 72;

[0126] When the prefabricated panels are double-sided, the panel transfer assembly 71 goes up after docking with the prefabricated panels transmitted by the outbound elevator 6 in the first round, and is transferred to the transmission line 1 through the turnover stacking machine 16. At this time, the transmission line 1 no longer puts in empty substrates until the turnover stacking machine 16 transfers all the prefabricated panels with single-sided materials to the transmission line 1. Then the panel transfer assembly 71 goes down after docking with the prefabricated panels transmitted by the elevator in the second round, and transfers the prefabricated panels to the cutting station 8 through the loading stacking machine 72.

[0127] Through the perfect design of each process station, the present invention can realize single-sided or double-sided paving of the substrate through only one transmission and maintenance line, without the need to repeatedly design multiple transmission and maintenance lines, thereby optimizing the process layout and greatly saving site space.

[0128] Example 4

[0129] Combine the following Figure 3-Figure 15 To introduce a prefabricated panel elevator structure and safety assurance system used in the production process.

[0130] See also Figure 6 The height of the upper plate waiting bracket 44 is the same as that of the inlet plate waiting bracket 33, and includes a first support frame at the bottom, a belt conveyor assembly 441 and a side support plate 442 at the top. The side support plate 442 is located outside the belt conveyor assembly 441. A front baffle 443 is provided at the end of the side support plate 442 away from the inlet plate waiting bracket 33 to limit the conveying position of the prefabricated plate. The front baffle 443 is located on the side of the elevator close to the stereoscopic warehouse 5. After the processed plate enters the upper plate waiting bracket 44 from the inlet plate waiting bracket 33, it continues to move forward under the transmission of the belt conveyor assembly 441 until it reaches the front baffle 443, and the side support plates 442 on both sides play an auxiliary supporting role.

[0131] See also Figure 7-Figure 12 The push plate mechanism 46 is located on the inner side of the upper plate transmission mechanism 45, and includes a second support frame and a second chain transmission assembly 461 assembled on it along the length direction. The movement direction of the second chain transmission assembly 461 is parallel to the transmission direction of the processing plate on the upper plate waiting bracket 44. A push plate 462 is connected under the second chain transmission assembly 461. When the push plate 462 is not working, it can be moved to the outside of the outer frame driven by the chain so as not to affect the upper movement of the processing plate.

[0132] The present invention uses chain transmission to drive the push plate 462 to work. The second chain transmission assembly 461 is arranged horizontally, and the middle part of the lower layer will have a drooping tendency. In order to prevent the processing plate from sliding out and hitting the chain when the push plate 462 is working, a chain support mechanism 466 is also provided at the lower end of the chain. Fig. 9 and Fig.12 shown.

[0133] The chain support mechanism 466 includes a rectangular tube 4661, a supporting plate 4662 and a locking pin 4663. At the same time, the pins connected to some chains on the second chain transmission assembly 461 are lengthened and extend out of the chain at one end.

[0134] The rectangular tube 4661 is fixed on the second support frame, and its bottom end is connected to the horizontally arranged supporting plate 4662 through the locking pin 4663. The other end of the supporting plate 4662 extends to the outer end surface of the chain, and enables the pins growing on the second chain transmission assembly 461 to slide on the upper surface of the supporting plate 4662 when passing through the supporting plate 4662, thereby preventing the lower chain of the second chain transmission assembly 461 from drooping and affecting the ejection of the plate.

[0135] The push plate mechanism 46 needs to run stably up and down on the outer frame 41 and be locked at any height, and it cannot affect the push-out of the processing plate below. Therefore, the stability and safety of its movement need to be given special consideration.

[0136] The first limiting mechanism 463, the second limiting mechanism 464 and the third limiting mechanism 465 are arranged on both left and right sides of both ends of the second supporting frame, with a total of four groups.

[0137] The first limiting mechanism 463 includes a limiting gear 4631 and a limiting rack 4632 meshing with each other;

[0138] The limiting rack 4632 is vertically arranged close to the first chain transmission assembly 451 toward the inner side, and the teeth of the limiting racks 4632 arranged front and rear on the outer frame 41 are arranged opposite to each other;

[0139] The limiting gear 4631 is located at the outermost sides of the two ends of the second support frame, and is connected to the transmission component at the back to drive the rotation;

[0140] The push plate mechanism 46 is moved up and down in the outer frame 41 by the first limiting mechanism 463, and the first level of safety is achieved by the meshing of the gear rack, and can be locked at a specified height. At the same time, the limiting racks 4632 arranged in front and back also lock the activity space of the push plate mechanism 46 in the front and back directions to prevent shaking in the front and back directions.

[0141] The second limiting mechanism 464 includes a limiting roller 4641, which is arranged at the lower part of the limiting gear 4631, with its axis perpendicular to the axis of the limiting gear 4631, and its outer surface is aligned with the side of the limiting rack 4632 away from the first chain transmission assembly 451;

[0142] The second limiting mechanism 464 limits the shaking of the push plate mechanism 46 in the left and right directions, thereby ensuring the stability of the up and down movement of the push plate mechanism 46.

[0143] The third limiting mechanism 465 includes a locking cylinder 4651 and an inserting strip 4652;

[0144] The inserting strip 4652 is vertically arranged on the back side of the limiting rack 4632 with the tooth surface, and a plurality of inserting holes are arranged on the outer side from top to bottom;

[0145] The locking cylinder 4651 is located between the limiting gear 4631 and the limiting roller 4641, with its axis parallel to the axis of the limiting gear 4631, and its telescopic end can be inserted into the insertion hole.

[0146] The third limiting mechanism 465 provides a second layer of safety protection. Even if the power system fails, the push plate mechanism 46 can be fixed in place and will not fall.

[0147] Regarding the safety guarantee system, after designing the push plate mechanism, the upper plate transmission mechanism, and the upper plate material support to efficiently transmit the processed plates, the elevator and the stereoscopic warehouse 5 can be made very high. However, when the elevator height is increased, it is easy to have the risk of tipping. Therefore, the present invention designs a triple anti-tipping mechanism to solve this problem.

[0148] First anti-tilt mechanism, see Figure 3 , Figure 4 and Fig.13 As shown, in the case where both the elevator and the stereoscopic warehouse 5 are high-rise, upper rails 43 are connected to the upper parts of both ends of the stereoscopic warehouse 5, and the upper rails 43 are arranged parallel to the bottom rails 42. Upper anti-tilt mechanisms 47 are provided on the upper parts of the inbound elevator 4 and the outbound elevator 6, and the upper anti-tilt mechanisms 47 are slidably connected to the upper rails 43 to ensure the safety of the elevator during operation and prevent tipping.

[0149] In this embodiment, the upper anti-tilt mechanism 47 includes a connecting plate 471, side rollers 472 and upper rollers 473. There are two sets of them, which are respectively located at the left and right ends of the upper part of the outer frame 43.

[0150] The connecting plate is an L-shaped member, the vertical section is connected to the outer frame 41, the horizontal section extends to the upper side of the upper track 43, and side rollers 472 with vertical axes are respectively connected below the front and rear ends of the horizontal section, and the two side rollers 472 are clamped on both sides of the upper track 43. When the elevator has a tendency to tip over in the front and rear directions, one of the two side rollers 472 will be stuck on the upper track 43, thereby preventing tipping.

[0151] The center of the horizontal section is equipped with an upper roller 473, and the rolling direction of the upper roller 473 is tangent to the length direction of the upper track 43. When the elevator has a tendency to tip over, one of the two upper rollers 473 will get stuck on the upper track 43 to prevent tipping.

[0152] Second anti-tilt mechanism, see Fig.14 The present invention provides a lower anti-tilt mechanism 48 at the left and right sides of the bottom of the elevator and at the release position of the front and rear bottom rails 42, specifically a clamping plate 481, the upper end of which is connected to the outer side of the bottom of the outer frame 41, and the lower end is clamped in the bottom rail 42. The bottom rail 42 can be an I-beam structure, and the shape of the lower end opening of the clamping plate 481 matches the shape of the upper part of the bottom rail 42, and the bottom opening is smaller than the internal opening, so as to prevent falling off from the bottom rail 42.

[0153] The card plate 481 is located on the outside of the wheel at the bottom of the outer frame 41. When the elevator moves on the bottom track 42, on the one hand, the card plate 481 can clear away bolts, nuts and other debris on the bottom track 42 to prevent the wheels from pressing on obstacles and causing tipping; on the other hand, when the elevator has a tendency to tip forward, backward or left and right, the lower part of the card plate 481 will be stuck on the bottom track 42, thereby preventing the elevator from tipping over.

[0154] The third anti-tilt mechanism, see Fig.15 A ground locking mechanism 49 is also provided between the bottom of the outer frame 41 and the bottom track. After the elevator moves to the specified position, it can be locked on the ground without shaking. On the one hand, it ensures that the positions of the inlet board waiting bracket 33, the upper board waiting bracket 44 and the three-dimensional warehouse 5 coincide with each other, and the processed boards are transmitted stably; on the other hand, it can prevent the elevator from tipping over to a certain extent.

[0155] Specifically, the ground locking mechanism 49 includes:

[0156] The first connecting seat 491 and the second connecting seat 492 are arranged at the bottom of the outer frame 41 along the length direction of the bottom track;

[0157] The first clamping jaw 494 and the second clamping jaw 495 are arranged parallel to the length direction of the bottom rail and are rotatably connected to the two ends of the lower part of the second connecting seat 492, and the adjacent sections of the first clamping jaw 494 and the second clamping jaw 495 are respectively provided with a sliding rod and a sliding hole;

[0158] A push cylinder 493, the fixed end of which is rotatably connected to the first connecting seat 491, and the telescopic end of which is rotatably connected to the end of the first clamping claw 494 away from the sliding rod;

[0159] The base 496 includes multiple bases, which are arranged on the ground between each upper plate material waiting support 44 and the three-dimensional warehouse 5, avoiding the bottom track.

[0160] When the elevator moves along the bottom track, the two clamps are in an open state, with a height higher than the base 496. After moving to a specified position, the push cylinder 493 pushes the two clamps downward to close and clamp on both sides of the base 496.
