Description

Technical Field

[0001] The utility model relates to the field of blank storage, in particular to a circulating blank storage system. Background Art

[0002] A blank storage machine can provide a stable quantity of blanks for subsequent processes such as glazing during the production process of ceramic products, etc., adjust the speed difference between each process, and make the production rhythm more coordinated; at the same time, when a certain link in the production line needs to be repaired, as a temporary reserve, it can prevent the entire production line from stopping immediately, provide a buffer time for repair and debugging, and reduce production losses.

[0003] The working mode of the blank storage machine is that the produced blanks enter the blank storage machine from the feeding end through a conveying device, and then the lifting mechanism lifts the blanks to the upper layer of the blank storage machine. When it is necessary to release the blanks, the blanks are taken out from the bottom up to the production line.

[0004] However, this working mode leads to the phenomenon of "first in, last out", that is, the blanks that enter the blank storage machine first cannot be taken out first. This imbalance in the storage order makes the residence time of the blanks in the blank storage machine inconsistent, and further increases the risk of quality problems such as color difference and deformation in the finished products. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the above problems and provide a circulating blank storage system, which can provide a first-in, first-out circulating blank storage system to improve the quality of finished products.

[0006] To achieve the above purpose, the technical solution adopted in this application is a circulating blank storage system, which includes a blank storage rack. A blank storage area and a blank discharging area are arranged horizontally in the blank storage rack. At least two layers of blank storage layers are arranged vertically in the blank storage area. A feeding port is arranged at one end of the lowest blank storage layer on the blank storage rack. A rack is arranged in each blank storage layer. Transmission belts are arranged at intervals along the length direction of the rack. A feeding area and a material transfer area are arranged at both ends of the blank storage layer in the conveying direction of the transmission belt. The feeding area of the upper blank storage layer is located above the material transfer area of the lower blank storage layer. A material transfer plate moving vertically is arranged in the material transfer area. A driving mechanism for pushing the blanks on the material transfer plate is arranged in the blank storage rack; the material transfer plate in the uppermost blank storage layer is located in the blank discharging area, and a discharging port is arranged at the lower part of the blank discharging area. The blanks enter the lowest blank storage area in the blank storage rack from the feeding port. As the blanks enter in sequence, the blanks that enter first gradually move to the upper blank storage layers. When it is necessary to take out the blanks, the blanks that enter the blank storage rack first are also taken out from the discharging port first. Through the above working mode, the residence time of the blanks in the blank storage machine is made as consistent as possible to improve the quality of finished products.

[0007] Further, to improve safety, extension parts are provided on the racks of the storage layers except the top storage layer. Elastic telescopic parts are provided on the extension parts. The elastic telescopic parts are located below the transfer plate. When there is no pressure from the transfer plate, the upper end surface of the elastic telescopic part is higher than the upper end surface of the conveyor belt. In this way, when the transfer plate does not move into place, the elastic telescopic part blocks the blank to prevent it from falling; the elastic telescopic part is driven by elasticity and the transfer plate, reducing the occurrence of safety accidents such as the blank falling due to the failure of the induction mechanism.

[0008] Further, a stop part is provided above the transfer plate of the top storage layer. The stop part moves vertically. In this way, when the transfer plate does not move into place, the stop part blocks the blank to prevent it from falling.

[0009] Further, to reduce the number of induction mechanisms and drive mechanisms, the stop part is driven to move vertically by the transfer plate and gravity. When there is no push from the transfer plate, the lower end surface of the stop part is located on the moving path of the blank. In this way, when the transfer plate moves to the highest point, the transfer plate pushes against the stop part to rise, enabling the blank to move onto the transfer plate. When the transfer plate carrying the blank descends to the discharge port, the stop part automatically descends under the action of gravity to hold the blank on the conveyor belt and move it towards the blank discharging area, thereby improving safety and reducing the occurrence of safety accidents such as the blank falling due to the failure of the induction mechanism.

[0010] Further, to install the stop part, the upper end of the stop part is connected to the top wall of the storage rack through a vertically arranged spring.

[0011] Further, a guide post is provided at the upper end of the stop part. The guide post is inserted and matched with the guide hole on the top wall of the storage rack. Through the cooperation of the guide post and the guide hole, the stability of the movement of the stop part is improved.

[0012] Further, the upper end of the guide post passes through the guide hole on the top wall of the storage rack and is connected to a baffle. The outer diameter of the baffle is larger than the inner diameter of the guide hole to prevent the stop part from falling.

[0013] Further, a limit part is provided at the distal end of the conveyor belt on the transfer plate to limit the movement position of the blank and ensure that the blank can be removed from the discharge port.

[0014] Further, to enable the blank to move between the conveyor belt and the transfer plate, supports are provided on both sides in the length direction of the storage layer. Conveyor belts are provided on the supports, and the conveyor belts on both sides are arranged oppositely.

[0015] Further, the supports are provided on the rack. A keyway and a guide key are provided in cooperation between the support and the rack. The support is fixed on the rack through a locking device to adapt to blanks of different specifications.

[0016] Advantages of the present application: The green bodies enter the blank storage area of the blank storage rack from the feed inlet in sequence. As the green bodies continuously enter, the green bodies that enter the blank storage area first also move to the connection between the topmost blank storage layer and the blank discharging area first. When it is necessary to take out the green bodies, the green bodies that enter the blank storage area first also enter the blank discharging area first, and then move out of the blank storage rack from the discharge outlet, so as to achieve the purpose of first-in, first-out, and improve the quality of the finished products.

[0022] In order to enable those skilled in the art to better understand the technical solution of the present utility model, the present utility model will be described in detail below with reference to the accompanying drawings. The description of this part is only exemplary and explanatory, and should not have any restrictive effect on the protection scope of the present utility model.

[0023] Embodiment 1, as Figures 1-3As shown in the figure, the structure of this embodiment is: a cyclic billet storage system, which includes a billet storage rack 1. Inside the billet storage rack 1, a billet storage area 2 and a billet discharging area 3 are arranged horizontally. Inside the billet storage area 2, at least two layers of billet storage layers are arranged vertically. In this embodiment, three layers of billet storage layers are set for illustration. At one end of the lowermost billet storage layer on the billet storage rack 1, a feeding port 4 is arranged, and the feeding port 4 is connected to the billet production line. The produced billets enter the billet storage area 2 from the feeding port 4. Inside each billet storage layer, a rack 5 is arranged. The rack 5 is arranged along the length direction of the billet storage area 2. Along the length direction of the rack 5, conveyor belts 6 are arranged at intervals. The conveyor belts 6 can adopt linear conveying mechanisms such as belt conveyors and roller conveyors in the prior art. At both ends of the billet storage layer in the conveying direction of the conveyor belt 6, a loading area 7 and a material transfer area are respectively arranged. The loading area 7 of the lowermost billet storage layer is located at one end of the feeding port 4 and is communicated with it. The loading area 7 of the upper billet storage layer is located above the material transfer area of the lower billet storage layer. In this way, an S-shaped billet storage channel is formed inside the billet storage area 2, which can reduce the floor area of the billet storage rack 1. Inside the material transfer area, a material transfer plate 8 that moves vertically is arranged. The material transfer plate 8 can be driven by linear driving mechanisms such as hydraulic cylinders, linear modules, and lead screws arranged vertically and driven by motors. The linear driving mechanism is installed on the billet storage rack 1. The lower material transfer plate 8 can move to the upper loading area 7 and is not lower than the upper end face of the conveyor belt 6 in the upper billet storage layer. On the material transfer plate 8, a limiting part 16 is arranged at the far end of the conveyor belt 6. The upper end face of the limiting part 16 is higher than the upper end face of the material transfer plate 8, so as to limit the moving position of the billet 9. Inside the billet storage rack 1, a driving mechanism for pushing the billet 9 on the material transfer plate 8 is arranged. The driving mechanism can adopt a cylinder that moves along the length direction of the conveyor belt 6, etc. The driving mechanism is installed on the billet storage rack 1 at the loading area 7. The material transfer plate 8 in the uppermost billet storage layer is located inside the billet discharging area 3. At the lower part of the billet discharging area 3, a discharging port 10 is arranged, and this material transfer plate 8 can move to the discharging port 10.

[0024] Specific working process: The produced billets 9 move from the feeding port 4 to the lowermost billet storage layer, and then under the drive of the conveyor belt 6, the billets 9 move to the upper end of the material transfer plate 8 of this layer. Then the material transfer plate 8 rises to carry the billets 9 to the loading area 7 of the second billet storage layer. Then the driving mechanism pushes the billets 9 on the material transfer plate 8 onto the conveyor belt 6 of the second billet storage layer until the billets 9 move to one side of the uppermost billet storage layer close to the billet discharging area 3. After the billets 9 on the material transfer plate 8 are pushed out, it resets to its own billet storage layer. Before the material transfer plate 8 resets, the conveyor belt 6 of this layer stops to prevent the billets 9 from falling. The position of the material transfer plate 8 can be sensed by a proximity switch, a photoelectric sensor, etc.

[0025] When it is necessary to take out the green body 9, the green body 9 in the uppermost storage layer close to the blank placing area 3 is moved onto the transfer plate 8. The transfer plate 8 descends to the discharge port 10. A pushing mechanism 19 is provided at the opposite end of the blank placing area 3 to the discharge port 10. The pushing mechanism 19 can adopt a hydraulic cylinder, an electric push rod, etc. The pushing mechanism 19 pushes the green body 9 out of the storage rack 1 and moves it to the production line. After the previously stored green body 9 is taken out, a position becomes vacant in the storage area 2 for storing newly produced green bodies 9, and the cycle continues in sequence.

[0026] Embodiment 2, as Figures 1-4 shown, the other mechanisms and working processes of this embodiment are the same as those of Embodiment 1. However, in this embodiment, to ensure that the green body does not move to the transfer area before the transfer plate 8 is reset, on the side walls of the racks 5 of the storage layers other than the uppermost storage layer, there are extension parts 11, and on the extension parts 11, there are elastic telescopic parts 12. Under the action of vertical pressure, the length of the elastic telescopic parts 12 can be shortened, and without external force, its length can be reset. In this embodiment, the elastic telescopic parts 12 can adopt spring telescopic rods. The elastic telescopic parts 12 are located at the lower end of the moving distance of the transfer plate 8. Without the pressure of the transfer plate 8, the upper end face of the elastic telescopic parts 12 is higher than the upper end face of the conveyor belt 6.

[0027] Above the transfer plate 8 of the uppermost storage layer, there is a stop part 13. The stop part 13 moves vertically under the drive of the transfer plate 8 and gravity. When there is no push from the transfer plate 8, the lower end face of the stop part 13 is on the moving path of the green body 9.

[0028] The upper end of the stop part 13 is connected to the top wall of the storage rack 1 through a vertically arranged spring 14. A guide post is provided at the upper end of the stop part 13, and the guide post is inserted and matched with the guide hole on the top wall of the storage rack 1. The spring 14 is sleeved on the guide post. The guide hole is penetrated. The upper end of the guide post passes through the guide hole on the top wall of the storage rack and is connected to the baffle 15 above the storage rack. The outer diameter of the baffle 15 is larger than the inner diameter of the guide hole.

[0029] Specific working process: Except for the transfer plate 8 of the uppermost layer, when the other transfer plates 8 are in the transfer area of their respective storage layers, the transfer plate 8 pushes the elastic telescopic part 12 downward, so that the elastic telescopic part 12 shortens. At this time, the green body on the conveyor belt 6 can move normally onto the transfer plate 8. When the transfer plate 8 rises, the elastic telescopic part 12 is no longer restricted and elongates, making the upper end face of the elastic telescopic part 12 higher than the upper end face of the conveyor belt 6. In this way, the green body on the conveyor belt 6 cannot move to the transfer area.

[0030] When the uppermost blank transfer plate 8 is located in the transfer area of the corresponding blank storage layer, the blank transfer plate 8 jacks up the stop portion 13, causing the lower end surface of the stop portion 13 to be higher than the upper end surface of the blanks 9 in this layer, so that the blanks can move onto the uppermost blank transfer plate 8. When the blank transfer plate 8 carrying the blanks descends to the discharge opening 10, the stop portion 13 loses its restraint and descends, causing the lower end surface of the stop portion 13 to be lower than the upper end surface of the blanks 9 in this layer, thereby preventing the blanks 9 from moving to the blank placing area 3.

[0031] Embodiment 3, as Figures 1-3 shown, the other mechanisms and working processes of this embodiment are the same as those of Embodiments 1-2. However, in this embodiment, supports 17 are provided on both sides of the blank storage layer in its length direction. A conveying mechanism such as a belt conveyor is provided on the supports 17. The conveyor belts 18 on the conveying mechanism extend out of the side walls of the supports 17. The conveyor belts 18 on both sides are arranged oppositely. The conveyor belts 18 are driven by motors. The two ends of the conveyor belts 18 are respectively located in the loading area 7 and the transfer area. In this way, the blanks in the loading area 7 and the transfer area can be driven to move onto the conveyor belt 6. At this time, the conveyor belt 6 can adopt rollers arranged at intervals along the length direction of the blank storage layer, and the rollers can be non-powered.

[0032] The supports 17 are arranged on the frame 5. A keyway and a guide key that cooperate with each other are provided between the supports 17 and the frame 5. The guide key and the keyway are respectively arranged on the supports 17 and the frame 5, and the guide key and the keyway are arranged along the width direction of the blank storage layer, so that the supports 17 can move along the width direction of the frame 5. The supports 17 are fixed on the frame 5 through a locking device. The locking device can adopt a T-shaped bolt. For this purpose, a T-shaped groove is provided on the frame 5.

[0033] Specific working process: Adjust the distance between the conveyor belts 18 on both sides according to the width of the blanks 9 to ensure that both conveyor belts 18 are in contact with the side walls of the blanks 9. In this way, the conveyor belts 18 can drive the blanks 9 to move between the loading area 7 and the transfer area.

[0034] It should be noted that in this article, the term "including", "comprising" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.

[0035] In this text, specific examples are used to elaborate on the principle and implementation mode of the present utility model. The description of the above examples is only used to help understand the method and its core idea of the present utility model. The above is only the preferred implementation mode of the present utility model. It should be noted that due to the limitation of literal expression, objectively there are infinite specific structures. For those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements, refinements or changes can be made, or the above technical features can be combined in an appropriate manner; these improvements, refinements, changes or combinations, or directly applying the concept and technical solution of the utility model to other occasions without improvement, shall all be regarded as the protection scope of the present utility model.
