Description

Technical Field

[0001] The present application relates to the technical field of roll welding, and in particular to a material tray storage device and an automatic material tray replacement device. Background Art

[0002] The roll welding machine is an important machine used to form the steel skeleton of cement products (such as drainage pipes, pipe piles for high-rise buildings and some chemical products). Its working principle is to spirally wind the steel bars wound on the material tray onto multiple main bars (also called main bars or steel bars) arranged along the axis, and then move the roll welding electrode to weld the steel bars to the main bars to complete the roll welding operation.

[0003] At present, the mode of replacing the material tray of the roll welding machine is that two workers work together to replace the material tray. Specifically, when replacing the material tray, the roll welding machine needs to stop and wait, and the two workers remove the bolts that fix the material tray on the left and right sides of the empty material tray to be replaced at the same time; after all the bolts are removed, the empty material tray is lifted to the material storage area by the overhead crane, and one of the workers needs to follow the overhead crane and the empty material tray to the material storage area, responsible for unloading the empty material tray to the material storage area, and then loading the full material tray onto the overhead crane; after that, the overhead crane lifts the full material tray to the installation hole of the roll welding machine, and the two workers then lock the bolts that fix the material tray on the left and right sides of the full material tray at the same time. In the above process, the process of unloading the empty material tray to the material storage area and loading the full material tray onto the overhead crane is completed manually, resulting in high labor intensity and long replacement time when replacing the material tray, which not only causes the roll welding machine to stop waiting for a long time, but also consumes a lot of human resources and has certain safety hazards.

[0033] An embodiment of the present application provides a tray storage device and an automatic tray replacement device, wherein the automatic tray replacement device includes a tray conveying device and a tray storage device, the automatic tray replacement device is used to supply full trays filled with materials to production equipment (such as a rolling welder), and to recover empty trays from the production equipment; the tray storage device is used to store trays and provide full trays to the tray conveying device, so that the tray conveying device can replace the full trays to the production equipment.

[0034] The following uses the automatic tray replacement device used in the roll welding system and used to replace the tray of the roll welding machine as an example to illustrate the structure of the tray storage device in the automatic tray replacement device. This embodiment is only used as an example and does not limit the technical scope of the present application. It is understood that in other embodiments, the automatic tray replacement device and the tray storage device of the present application are not limited to supplying trays to the roll welding machine and replacing the trays of the roll welding machine, but can also be used to supply trays to any production equipment that needs to use trays and replace trays, which is not limited here.

[0035] See also Figure 1 , Figure 1The schematic diagram of the structure of the automatic tray replacement device 10 in one embodiment of the present application is shown. The automatic tray replacement device 10 provided in one embodiment of the present application includes a tray handling device 100 and a tray storage device 200, wherein the tray storage device 200 is arranged on a tray storage station 11, and the roll welding machine 20 is arranged on a tray replacement station 12, and the tray replacement station 12 and the tray storage station 11 are arranged at intervals in a conveying direction (the X direction shown in the figure). Figure 1 In the embodiment shown in , there are two tray storage devices 200, and the two tray storage devices 200 are adjacently arranged along the conveying direction, wherein one tray storage device 200 is used to store empty trays, and the other tray storage device 200 is used to store full trays; the tray handling device 100 can travel back and forth between the tray changing station 12 and the tray storage station 11. On the one hand, the tray handling device 100 can unload the empty tray from the roll welding machine 20 at the tray changing station 12 and transport it to the tray storage station 11, and then place the empty tray in the tray storage device 200 at the tray storage station 11; on the other hand, the tray handling device 100 can transport the full tray from the tray storage station 11 to the tray changing station 12, and unload the full tray onto the roll welding machine 20, thereby completing the automatic replacement of the tray 30.

[0036] Specifically, see Figure 2 , is a structural schematic diagram of a material tray storage device 200 according to an embodiment. The material tray storage device 200 according to this embodiment includes a base 210, a silo assembly 220 and a driving source 230. The silo assembly 220 is slidably arranged on the base 210. The base 210 is used to provide support for the silo assembly 220. The silo assembly 220 is used to carry the material tray 30. The driving source 230 is arranged on the base 210. The silo assembly 220 is connected to the output end of the driving source 230. The driving source 230 is used to drive the silo assembly 220 to move relative to the base 210 along a transfer direction perpendicular to the conveying direction (the Y direction shown in the figure). The purpose of such design is that when the tray handling device 100 moves to a position opposite to the tray storage station 11 and the tray storage device 200, the tray storage device 200 can be close to the tray handling device 100, so that the tray handling device 100 can transfer the empty tray replaced from the rolling welding machine 20 to the silo assembly 220 of the tray storage device 200, or the tray storage device 200 can transfer the full tray stored in the silo assembly 220 to the tray handling device 100.

[0037] More specifically, see Figure 3The silo assembly 220 has a fence 221, which encloses a storage space for accommodating the tray 30. The top and one side of the accommodating space 220a have openings, so that the tray handling device 100 or the crane can place the tray 30 into the accommodating space 220a from the side opening or the top opening of the accommodating space 220a, or can take the tray 30 out of the accommodating space 220a through the side opening or the top opening of the accommodating space 220a.

[0038] It is understandable that the accommodating space 220a may have openings on more than one side, and may also have openings on both sides, which is not limited here.

[0039] Preferably, since the material tray 30 is heavy, in order to make the material tray 30 more easily placed in the receiving space 220a of the silo assembly 220, at least one side wall of the receiving space 220a is inclined relative to the vertical direction (the Z direction shown in the figure), and the side wall inclined relative to the vertical direction is provided with a guide block 223, and the guide block 223 has a guide bar 2231, and the guide bar 2231 is also inclined relative to the vertical direction, so that when the material tray 30 is about to be placed in the receiving space 220a and contacts the guide bar 2231 of the guide block 223, the material tray 30 can be more easily placed in the receiving space 220a under the guiding action of the guide bar 2231.

[0040] It is worth noting that after the material tray 30 is placed in the accommodation space 220a, the position of the material tray 30 in the accommodation space 220a may be incorrect, making it inconvenient to remove the material tray 30. As an improvement to the above embodiment, an adjustment block 224 is further provided on the side wall of the accommodation space 220a. The adjustment block 224 is fixedly arranged on the side wall of the accommodation space 220a by screws, and is used to abut against the material tray 30 after the material tray 30 is placed in the accommodation space 220a. By turning the screw, the distance between the adjustment block 224 and the side wall of the accommodation space 220a can be adjusted, so that the position of the material tray 30 can be adjusted, so that the position of the material tray 30 in the accommodation space 220a is placed correctly so that the material tray handling device 100 can remove the material tray 30.

[0041] Better yet, please continue reading Figure 3 The fence 221 is provided with a stopper 225 at the edge of the opening of the accommodating space 220a. By providing the stopper 225, the material tray 30 can be prevented from sliding off the silo assembly 220, thereby avoiding safety accidents. Figure 3 As shown in , a stopper 225 can be respectively provided at the two edges of the opening side of the accommodating space 220a, or only one stopper 225 can be provided at one edge of the opening side, as long as it can prevent the material tray 30 from sliding out of the silo assembly 220, and no limitation is made here.

[0042] In this way, when the overhead crane or the tray handling device 100 is about to place the tray 30 into the silo assembly 220, the tray 30 can be lifted to avoid the block 225, so that the tray 30 can be placed in the accommodating space 220a or taken out of the accommodating space 220a.

[0043] Furthermore, the opposite side walls of the storage space 220a are also provided with a photoelectric detector 222, which is used to detect whether the material tray 30 is placed in the storage space 220a. Specifically, the photoelectric detector 222 includes a transmitter and a receiver, which are respectively arranged on the opposite side walls of the storage space 220a, so that the transmitter and the receiver are arranged relative to each other, the transmitter is used to emit light, and the receiver is used to receive light. When the receiver can receive light, it can be determined that there is no material tray 30 in the storage space 220a. When the receiver cannot receive light, it can be determined that the material tray 30 has been placed in the storage space 220a, so as to detect whether the material tray 30 is stored in the silo assembly 220.

[0044] See also Figure 3 and Figure 4 In order for the silo assembly 220 to move smoothly along a predetermined path relative to the base 210, a guide rail 211 is provided on the base 210, and a slider 226 is correspondingly provided on the silo assembly 220. The slider 226 is slidably connected to the guide rail 211, so that when the silo assembly 220 slides relative to the base 210, the friction between them can be reduced, thereby reducing jamming.

[0045] For further information, please refer to Figure 4 The base 210 is provided with a guide rail cover plate 212, which covers at least a portion of the guide rail 211 to prevent excessive dust from adhering to the surface of the guide rail 211, thereby affecting the sliding of the guide block 223 on the guide rail 211. Figure 4 As shown in the figure, the guide rail cover plate 212 is inverted L-shaped to form a cover space 212a with a side opening, the guide rail 211 is accommodated in the cover space 212a, and the slider 226 extends from the side opening of the cover space 212a into the cover space 212a and is slidably connected to the guide rail 211.

[0046] In addition, in order to ensure that the driving source 230 drives the silo assembly 220 to move within a preset range of movement relative to the base 210, the base 210 is provided with limit switches 213 at the first position and the second position spaced apart from each other, and the limit switches 213 are used to enable the silo assembly 220 to move only between the first position and the second position. The specific working principle is that when the silo assembly 220 moves to the first position or the second position, the limit switch 213 can be triggered, and the limit switch 213 sends a signal to the control module of the driving source 230, and the control module controls the action of the driving source 230 to stop the silo assembly 220 at the first position or the second position, so as to avoid the silo assembly 220 from moving beyond the preset position.

[0047] Optionally, the base 210 is also provided with a buffer 214 connected to the driving source 230 through a pipeline, and the buffer 214 is used to ensure that the silo assembly 220 can smoothly stop at the first position or the second position when moving relative to the base 210. Exemplarily, when the driving source 230 is a hydraulic cylinder, the buffer 214 corresponds to a hydraulic buffer, and its working principle is mainly based on the pressure and flow of the liquid to absorb and eliminate the impact and vibration generated in the mechanical movement. Specifically, when the hydraulic buffer is subjected to an external force, the piston of the driving source 230 will be pushed, so that the silo assembly 220 moves, and the hydraulic oil in the driving source 230 will be squeezed in this process. The hydraulic oil is squeezed out of the annular gap between the piston and the push rod and enters the oil storage chamber. When the piston just starts to move, the oil is easily squeezed out due to the large annular gap; as the piston continues to move, the annular gap gradually becomes smaller, resulting in a gradual increase in the resistance of the piston. When the piston reaches the cylindrical stage of the push rod, the annular gap is zero and the resistance reaches the maximum value. In this process, the hydraulic buffer uses the piston to squeeze the hydraulic oil to do work, consumes a lot of kinetic energy, and plays a buffering role. When the external force disappears, the return spring will rebound the piston to its original position, and the hydraulic oil will flow back to the lower cavity of the piston through the oil return hole and the oil discharge hole to prepare for the next action, so that the moving silo assembly 220 can be smoothly stopped at the first position or the second position.

[0048] The following, combined with Figure 1 , Figure 5 and Figure 6 The operation flow of the tray storage device 200 will be described.

[0049] like Figure 5As shown, when it is necessary to put the tray 30 into the tray storage device 200, for example, when it is necessary to put a full tray into the tray storage device 200, the overhead crane moves the full tray to the top of the tray storage device 200, and the driving source 230 retracts, so that the silo assembly 220 moves from the first position (point A as shown in the figure) to the second position (point B as shown in the figure), and is guided by the guide block 223 so that the tray 30 enters the storage space 220a of the silo assembly 220. At this time, the reflected photoelectric 222 detects that there is a tray 30 in the storage space 220a, and the limit switch 213 detects that the silo assembly 220 has moved into place. Similarly, Figure 6 As shown, when it is necessary to put the empty tray unloaded from the rolling welding machine 20 into the tray storage device 200, the tray conveying device 100 moves to the position opposite to the tray storage station 11 and the tray storage device 200, and the driving source 230 extends to drive the silo assembly 220 to move from point B to point A, so that the silo assembly 220 and the tray conveying device 100 are close to each other, and the tray conveying device 100 itself is also close to the tray storage device 200, and then carries the empty tray down, relying on the guide block 223 for guidance, so that the tray 30 enters the accommodating space 220a of the silo assembly 220, and at this time, the reflected photoelectric 222 detects that there is a tray 30 in the accommodating space 220a, and the limit switch 213 detects that the silo assembly 220 moves into place.

[0050] Similarly, when a full tray needs to be removed from the tray storage device 200, the driving source 230 is extended to drive the bin assembly 220 to move from point B to point A, so that the bin assembly 220 and the tray handling device 100 are close to each other. At this time, the reflected photoelectric 222 detects that there is a tray 30 in the accommodating space 220a, and the limit switch 213 detects that the bin assembly 220 has moved into place. Then the tray handling device 100 removes the full tray, and the reflected photoelectric 222 detects that the tray 30 has been removed, and then the bin assembly 220 returns from point A to point B, and the limit switch 213 detects that the bin assembly 220 has returned into place.

[0051] It can be seen that the tray storage device 200 and the automatic tray changing equipment 10 provided in the present application can automatically transfer empty trays to the silo assembly 220 of the tray storage device 200, or the tray storage device 200 can automatically transfer full trays to the tray handling device 100, thereby eliminating the need for workers to manually unload empty trays to the material storage area, and eliminating the need for workers to manually load full trays onto the overhead crane. This reduces the time spent on replacing the tray 30, thereby reducing the downtime and waiting time of the rolling welder 20, and also reduces the labor intensity of workers, avoiding the occurrence of safety hazards.

[0052] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0053] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
