Description

Technical Field

[0001] The invention relates to automated production equipment, in particular to an axle gravity silo with an automatic feeding function. Background Art

[0002] With the development of economy and construction, as well as the popularization of mechanization, the construction scale and production scale of all walks of life are expanding rapidly, and the requirements for automatic feeding mechanisms are getting higher and higher. In the existing mechanical manufacturing field, material handling and loading and unloading of workpieces are relatively weak links. The existing feeding mechanism cannot meet the actual production requirements due to its complex structure, difficult manufacturing, and high price. It also requires a lot of manpower and material resources, which not only makes its labor cost high, but also has certain risks, and also greatly reduces the level of production automation.

[0003] Especially for the loading of shaft bar structures, since this type of material is a cylindrical structure with a certain length, it will roll and cannot be positioned, and will be placed in a disorderly manner horizontally and vertically. This makes it impossible to achieve automatic loading operations. In actual use, a silo will be set at the position of the loading mechanism for stacking the bars. However, it is only a bracket and cannot achieve automatic loading or adjust the size to meet the needs of bars of different lengths. Summary of the invention

[0004] The purpose of the present invention is to overcome the defects of the prior art and provide a shaft-type gravity silo, which adopts an adjustable loading silo structure and can match rods of various sizes to improve its versatility. The loading structure adopts a lifting cylinder in conjunction with a loading seat, an inclined bottom surface and a loading platform plate, and utilizes the dead weight of the rods to make them roll into a V-shaped discharge rack, thereby effectively realizing automatic loading.

[0005] To achieve the above object, the present invention proposes the following technical solution: an axial gravity silo, comprising a support frame, a material storage bin installed above the support frame, and a lifting and loading mechanism installed on the front end surface of the material storage bin, wherein:

[0006] The material storage bin comprises a bottom plate, two side plates, a front fixed plate and a rear fixed plate, the bottom plate is tilted and fixed between the two side plates, a gap is provided between the front end and the front fixed plate, the two side plates are connected by a connecting rod at the top, a fixed side plate and an adjustable side plate are arranged in parallel between the two side plates, the fixed side plate passes through the connecting rod, the bottom edge of the fixed side plate is fixed to the bottom plate, the adjustable side plate is sleeved on the connecting rod through a shaft sleeve, and can move back and forth along the connecting rod, and a width-adjustable upper material storage bin is formed between the adjustable side plate and the fixed side plate;

[0007] The loading mechanism includes a lifting cylinder, a slide rail, an adjustment plate, a connecting block, a loading seat, a unloading platform plate, and a V-shaped unloading rack. The lifting cylinder is fixed between the support frame and the outer side of the front fixed plate. The slide rail is installed on the outer side of the front fixed plate and is parallel to the lifting cylinder. The telescopic rod of the lifting cylinder is connected to the slider on the slide rail. The front fixed plate is provided with two vertical notches. The adjustment plate is placed on the inner side of the front fixed plate and is fixed to the slider through the connecting block through the notch, and the adjustment plate is fitted with the front end surface of the bottom plate of the material storage bin. The loading seat is installed on the top of the adjustment plate, and the unloading platform plate is obliquely installed on the top of the front fixed plate. The V-shaped unloading rack is fixed to the front end of the unloading platform plate.

[0008] Preferably, a plurality of through holes are arranged at intervals on the unloading platform plate, and a plurality of buffer bars are installed at intervals on the slider. When the lifting cylinder is extended so that the loading seat is flush with the unloading platform, the buffer bar passes through the through holes to form a buffer blocking structure, thereby preventing the rods from rolling directly into the V-shaped unloading rack.

[0009] Preferably, a guide baffle is installed in the V-shaped unloading rack, the upper end of the guide baffle is inclined outward to form a guide structure, the lower end of the guide baffle is fixed to the V-shaped unloading rack by a fastener, and the relative fixed position is adjustable.

[0010] Preferably, the positioning cylinder is installed on the unloading platform plate through a bracket, located on the side of the V-shaped unloading rack and arranged opposite to the guide baffle.

[0011] Preferably, a plurality of groups of blocking blocks are arranged on the fixed side plates and the adjusting side plates corresponding to the loading bin, and a gap is provided between the bottom of the blocking block and the bottom plate for the rods to pass through, and the size of the gap is 1.5 to 2 times the diameter of the rods.

[0012] Preferably, the inclination angle of the bottom plate is 10-15°.

[0013] Preferably, a U-shaped protective plate is installed above the support frame and located at the front end of the material storage bin.

[0014] Preferably, mounting plates are welded on the four corners of the bottom of the support frame, and each mounting plate is equipped with an adjusting foot and a universal wheel.

[0015] Preferably, the loading seat has an inclined receiving platform, and its inclination angle is consistent with the inclination angle of the unloading platform.

[0016] Preferably, the inclination angle of the unloading platform plate is 10~15°.

[0017] Compared with the prior art, the shaft-type gravity silo disclosed in the present invention has the following beneficial effects:

[0018] Versatility: The partition design of the opposing silos allows the size of the upper silo to be adjusted through adjustable side panels, making it suitable for bars of different lengths and increasing its versatility;

[0019] Smoothness: Multiple groups of blocking blocks of different lengths are set on the side wall of the loading bin, and the gap between the blocking blocks and the bottom plate is adjusted to ensure that the number of bar accumulation is smaller as it is closer to the loading side. At the same time, the cylindrical structure of the bar and the inclined bottom plate structure are used so that if there is a lack of bar at the front end, the rear end will automatically roll over without any operation. This adjustment of the accumulation quantity reduces the rising resistance of the loading structure and ensures smoothness of loading;

[0020] High efficiency: The loading structure uses a lifting cylinder with an adjustment plate, a loading seat and a slide block to automatically lift the bar material, and then cooperates with the inclined unloading platform plate to make the bar material automatically roll onto the V-shaped unloading rack, which is convenient for the robot to grab. The automatic operation of the cylinder improves the efficiency of loading;

[0021] Stability: The bottom plate, loading seat and unloading platform plate are tilted to make the bar material roll by its own weight. In order to improve the stability of rolling and the accuracy of position, a buffer lever is designed to divide the rolling process from direct rolling to the right position into two steps, thereby reducing its rolling speed and ensuring that it falls stably on the discharge rack. At the same time, a guide baffle is set to guide the rolling path to ensure that it falls into the specified position of the discharge rack, thereby improving its stability and accuracy.

DETAILED DESCRIPTION

[0029] The following embodiments of the technical solution of the present invention are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and are therefore only used as examples, and cannot be used to limit the protection scope of the present invention.

[0030] like Figures 1 to 5 As shown, the present invention discloses an axial gravity silo, which is mainly used for silo-type loading of various cylindrical rods of metal, plastic, nylon, etc. Its structure includes a support frame 1, a storage bin 2 installed above the support frame 1, a U-shaped protective plate 3 installed on the support frame 1 and located at the front end of the storage bin, and a jacking and loading mechanism installed on the front end surface of the storage bin, and the jacking and loading mechanism is located in the U-shaped protective plate.

[0031] Specifically, the support frame 1 is a frame structure composed of multiple aluminum alloy profiles, with mounting plates 4 welded on the four corners of the bottom. Each mounting plate is installed with an adjustment foot 5 and a universal wheel 6. The use switch between the adjustment foot and the universal wheel can be achieved by adjusting the extension length of the adjustment foot.

[0032] The material storage bin is assembled from a bottom plate 7, side plates 8 on both sides, a rear fixed plate 9 and a front fixed plate 10. The bottom plate is installed between the side plates on both sides at an inclination of 10-15°, and the end close to the front fixed plate is lower and has a gap with the front fixed plate. The side plates on both sides are fixed to the support frame and are connected above by a connecting rod 11. A fixed side plate 12 and an adjustable side plate 13 are arranged in parallel between the side plates on both sides. The fixed side plate passes through the connecting rod, and the bottom edge is fixed to the bottom plate. The adjustable side plate is mounted on the connecting rod through a shaft sleeve 14, and the bottom edge is not connected to the fixed plate. A loading bin is formed between the adjustable side plate and the fixed side plate. The width of the loading bin is adjusted by moving the adjusting side plate back and forth along the connecting rod. The adjustment of the width is determined according to the length of the bar material. This adjustment structure makes it suitable for bars of different lengths, thereby improving its versatility.

[0033] The U-shaped protective plate is installed at the front end of the material storage bin to form a protective zone between the material storage bin to protect the safety of the jacking and loading mechanism installed in the protective zone. The protective plate can be selected not to be installed according to needs in actual use.

[0034] The jacking and feeding mechanism includes a jacking cylinder 15, a slide rail 16, an adjustment plate 17, a connecting block 18, a feeding seat 19, a feeding platform plate 20, and a V-shaped unloading rack 21. The lower end of the jacking cylinder is fixed to the support frame, and the upper end is fixed to the outer side of the front fixed plate. The slide rail is installed on the outer side of the front fixed plate and is arranged parallel to the jacking cylinder. The telescopic rod of the jacking cylinder is connected to the slider 23 on the slide rail. The front fixed plate is provided with two notches 22, which are vertically arranged and pass through the front and back. The adjustment plate is placed on the inner side of the front fixed plate and is fixed to the slider through the notch by the connecting block. Since there is a gap between the bottom plate and the front fixed plate, the gap is for facilitating the up and down movement of the adjustment plate. In order to prevent the rod material from falling from the gap, it is necessary to fit the adjustment plate with the front end surface of the bottom plate to facilitate the adjustment plate to pass through and move up and down. The feeding seat is installed on the top of the adjustment plate. The material seat has an inclined material receiving platform 24, and the unloading platform plate is installed on the top of the front fixed plate, and the unloading platform plate is inclined downward by 10~15° relative to the horizontal plane. The inclination angle of the inclined material receiving platform is consistent with that of the unloading platform, which can ensure that the inclined surfaces are in the same straight line when the two are flush. The V-shaped material discharge rack is fixed at the front end of the unloading platform plate. When in use, the jacking cylinder retracts to move the adjustment plate down to the bottom of the loading bin. Since the bottom plate of the loading bin is inclined, the shaft bars roll onto the loading seat under the action of gravity. By controlling the distance between the inclined material receiving platform and the front fixed plate, only one bar can be accommodated on the material receiving platform. As the jacking cylinder is lifted, the excess bars automatically fall off. When the adjusting plate moves up to make the loading seat flush with the unloading platform, due to the inclination of the material receiving platform, the unloading platform plate is also inclined, and they are in the same straight line, so the bars automatically roll into the V-shaped material discharge rack to realize automatic loading.

[0035] In actual use, since some rods are made of metal and are heavy, they will have great inertia when rolling and may fall out of the V-shaped unloading rack. Therefore, a plurality of through holes 25 are arranged at intervals on the unloading platform plate, and a plurality of buffer bars 26 are installed at intervals on the slider. When the lifting cylinder is extended so that the loading seat is flush with the unloading platform, the buffer bar passes through the through hole to form a buffer blocking structure, so that the rod cannot directly roll into the V-shaped unloading rack, but is blocked at the buffer bar. When the lifting cylinder is retracted, the buffer bar moves down so that the rod rolls again from a stationary state and falls into the V-shaped unloading rack. The addition of this structure divides the loading of the rod from the original direct rolling into two rollings, reduces its rolling acceleration, and ensures that it falls into the V-shaped unloading rack at a low speed without falling out.

[0036] In addition, in order to accurately position the rods falling into the V-shaped discharge rack, a guide baffle 27 is provided in the V-shaped discharge rack. The upper end of the guide baffle is tilted outward to form a guide structure 28, thereby ensuring that the raw materials rolling down from above fall into this area. The lower end of the guide baffle is fixed to the V-shaped discharge rack by fasteners. Since the length of the raw materials exists in various forms, the relative fixed position between the guide baffle and the V-shaped discharge rack can be adjusted. In addition, a positioning cylinder 29 is installed on the side of the V-shaped discharge rack and fixed to the unloading platform plate through a bracket 30. When the raw materials roll to this position, the positioning cylinder extends to push the end of the raw materials against the guide baffle. Since this part is for loading, and the loading is completed by a loading robot, a signal needs to be generated here to inform the loading robot to operate. Therefore, a proximity switch 31 is installed on the guide baffle. When the raw materials are against the guide baffle, the proximity switch is triggered.

[0037] In the present structure, in order to improve the smoothness of loading, a plurality of groups of blocking blocks 32 are arranged on the fixed side plates and the adjusting side plates corresponding to the loading bin. There is a gap between the bottom of the blocking block and the bottom plate. The size of the gap is 1.5 to 2 times the diameter of the rod, which can ensure that the rods roll to the front loading area one by one. This structure makes it possible for a large amount of raw materials to accumulate at the rear end while the amount of raw materials at the front end will be greatly reduced when loading in the loading bin, thereby reducing the accumulation of raw materials in the loading seat area, reducing the resistance to the top material when the loading seat rises, and ensuring the smoothness of loading.

[0038] The gravity silo of the present invention can be used for bars of various sizes and specifications. For bars of different lengths, the width of the silo can be adjusted by adjusting the side plates. For bars of different diameters, the distance between the adjustment plate and the front fixed plate can be changed by replacing the loading seats and connecting blocks of different sizes, and the gap between the bottom plate and the front fixed plate can be adjusted at the same time to achieve width adjustment to meet the needs of bars of different diameters.

[0039] In addition, it also includes an electric control cabinet 33 installed on the support frame, which is electrically connected to the lifting cylinder, proximity switch and positioning cylinder to achieve corresponding control. The control principle and connection method of the control cabinet can refer to the relevant connections of the existing electric control cabinet. It is not the focus of protection of the present invention, so it is not described in detail.

[0040] The present invention discloses an axial gravity silo, whose working principle is as follows: the adjustable side plate is adjusted according to the length of the bar, and then the material is loaded into the upper silo, the lifting cylinder is retracted, the loading seat moves down so that a bar falls onto the loading seat, the lifting cylinder is extended, and the loading seat is lifted to be flush with the unloading platform plate. At this time, the buffer lever is also extended, and the bar rolls to the buffer lever and stops under the action of gravity, and then the lifting cylinder is retracted again, and the bar rolls again into the V-shaped discharge rack, and the positioning cylinder is extended to push the bar toward the guide baffle, triggering the proximity switch, so that the robot comes to pick up the material.

[0041] The present invention discloses an axial gravity silo, which adopts an adjusting structure to adjust the size of the loading silo, so as to match bars of various sizes and improve its versatility. The loading structure adopts a lifting cylinder in conjunction with a loading seat, an inclined bottom surface and a loading platform plate, and utilizes the dead weight of the bar to make it roll into a V-shaped discharge rack, thereby effectively realizing automatic loading.

[0042] The technical contents and technical features of the present invention have been disclosed as above. However, those skilled in the art may still make various substitutions and modifications based on the teachings and disclosures of the present invention without departing from the spirit of the present invention. Therefore, the protection scope of the present invention should not be limited to the contents disclosed in the embodiments, but should include various substitutions and modifications that do not depart from the present invention and are covered by the claims of this patent application.
