Description

Technical Field

[0001] This utility model belongs to the technical field of logistics and warehousing equipment, and relates to a single bar stock entry and exit buffer device. Background Technology

[0002] With the development of automated warehousing technology, various industries are demanding increasingly more automated products. Simultaneously, the diverse forms of materials and warehousing methods place higher requirements on inbound and outbound equipment. For single-bar inbound and outbound operations, the traditional method uses lifting devices combined with manual handling to pick up and store each bar. This approach is characterized by low automation, high labor intensity, and low efficiency. Furthermore, for warehousing systems, the traditional manual handling method is not only inconvenient to operate, but the bar counting is also non-automated. Manual counting is prone to errors, and incorrect inbound and outbound data can lead to distorted warehousing data. Correcting this data requires re-counting, which is time-consuming, labor-intensive, and severely impacts warehousing and logistics efficiency. Utility Model Content

[0003] To overcome the shortcomings of existing technologies, this utility model provides a single bar stock entry and exit buffer device. The purpose is to design a single bar stock entry and exit buffer device to meet the needs of single bar stock entry and exit, serving as the entry and exit connection device of the centralized bar stock storage system. This device automates the entry and exit of bar stocks into or out of the buffer device, thus replacing manual labor and reducing labor intensity. Furthermore, the automatic entry and exit of single bars facilitates counting and improves the storage and logistics efficiency of bar stocks.

[0004] To achieve the above-mentioned objectives, this utility model provides the following technical solution.

[0005] A single bar stock in / out buffer device includes a base frame with a tilting frame hinged to its upper end. One end of a tilting cylinder is connected to the base frame, and the other end is connected to the tilting frame to drive the tilting frame to rotate. A stop block is fixed at the rear end of the tilting frame to prevent bar stock laid flat on the upper surface of the tilting frame from falling off the rear end. Columns fixed to the base frame are respectively provided on the left and right sides of the front end of the tilting frame. An inbound picking plate and an outbound picking plate, which can slide up and down, are respectively connected to the left and right sides of each column. The telescopic ends of the inbound and outbound cylinders fixed to the base frame are respectively connected to the inbound and outbound picking plates to control their lifting and lowering. The upper end of the inbound picking plate has a first inclined surface with its lower end facing the stop block. The material receiving plate has a front-loading hook and a rear-loading hook, which are located in front of and behind the column, respectively, on the front and rear sides of its top. The material receiving plate has a second inclined surface with its upper end facing the stop block. The material receiving plate has a front-loading hook, which is located in front of the column, on the front side of its top. The distance D from the rear side of the top of the second inclined surface to the rear end of the column is greater than the radius of the bar stock and less than the diameter of the bar stock. The distance E from the front end of the rear-loading hook to the rear end of the column is greater than the diameter of the bar stock and less than 1.5 times the diameter of the bar stock. The hydraulic pump station is connected to the pipelines of the tilting cylinder, the receiving cylinder, and the receiving cylinder to control their extension and retraction.

[0006] As a further optimization, the hydraulic pump station is located in the middle of the base frame and below the tilting frame.

[0007] As a further optimization, there are multiple tilting frames hinged to the base frame, evenly spaced along the left and right direction; each tilting frame is connected to a tilting cylinder; the front end of each tilting frame corresponds to a pair of columns, and each column corresponds to an inbound material picking plate and an outbound material picking plate; each inbound material picking plate and each outbound material picking plate correspond to an inbound cylinder and an outbound cylinder, respectively.

[0008] As a further optimization, an inbound rack is fixedly connected to the rear side of the inbound picking plate; each inbound rack is meshed with an inbound gear, the inbound gear is fixedly connected to the inbound drive shaft, and the inbound drive shaft is rotatably connected to the base frame for controlling the synchronous lifting and lowering of all the inbound picking plates.

[0009] As a further optimization, an outgoing rack is fixedly connected to the rear side of the outgoing material picking plate; each outgoing rack is meshed with an outgoing gear; the ingoing gear is fixedly connected to the outgoing drive shaft, and the outgoing drive shaft is rotatably connected to the base frame for controlling the synchronous lifting and lowering of all the outgoing material picking plates.

[0010] As a further optimization, the base frame is equipped with several displacement sensors to monitor the rising and falling positions of the inbound and outbound material picking plates.

[0011] As a further optimization, the distance value D is equal to 1.2 times the radius of the bar stock, and the distance value E is equal to 1.2 times the diameter of the bar stock.

[0012] The method of using the bar stock single bar stock inbound and outbound buffer device is as follows: In the initial state, both the inbound picking plate and the outbound picking plate are located below the top of the column; the high end of the tilting frame faces forward and is lower than the top of the column;

[0013] When bar stock is received into the warehouse, the following steps are included:

[0014] S1: First, transport the single bar to the front of the in-warehouse picking hook at the front of the in-warehouse picking plate. The bar rolls backward along the first inclined plane until it reaches the front of the top support column.

[0015] S2: The oil cylinder extends and pushes the material picking plate of the warehouse to rise until the bar on the first inclined surface exceeds the top of the column. Then the bar rolls forward along the first inclined surface until it reaches the top support of the picking hook.

[0016] S3: The warehousing cylinder retracts, pulling the warehousing picking plate down until the bar material on the first inclined surface falls onto the upper end of the tilting frame. The bar material slides along the inclined upper end of the tilting frame into the rear end of the tilting frame; warehousing is completed.

[0017] When bar stock is released from the warehouse, the following steps are included:

[0018] S4: The tilting cylinder extends, driving the tilting frame to rotate until its high end faces backward and its low end faces forward, so that the bar stock laid flat on the tilting frame slides forward until the rear end of the top support column of the bar stock at the front end.

[0019] S5: The outgoing cylinder extends, pushing the outgoing material picking plate upward so that the foremost bar falls into the second inclined surface;

[0020] S6: The material picker plate continues to rise until the bar on the second inclined plane exceeds the top of the column. Then the bar rolls forward along the second inclined plane until it reaches the top of the material picker hook.

[0021] S7: The outbound cylinder retracts, the tilting cylinder retracts, and the initial state is restored; the bar stock located at the outbound hook is transferred, and the outbound process is completed.

[0022] As a further optimization, when bar stock is put into storage, the storage picking plate is raised and then lowered, and a count is performed once to obtain the storage data for a single bar stock; when bar stock is taken out of storage, the exit picking plate is raised and then lowered, and a count is performed once to obtain the exit data for a single bar stock.

[0023] As a further optimization, the lifting detection of the inbound and outbound material picking plates is achieved by displacement sensors installed on the base frame.

Detailed Implementation

[0033] The present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are merely some preferred embodiments of the present invention, and not all embodiments. Those skilled in the art should understand that these embodiments are merely used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. For ease of description, [the following is a simplified description of the embodiments]. Figure 1 The directions shown are described in front, back, left, right, top, and bottom.

[0034] Example 1: Please refer to Figure 1-6 ;

[0035] A single bar stock entry / exit buffer device is applied in a centralized bar stock storage system to facilitate single bar stock access. The buffer device is installed between the bar stock storage warehouse and the bar stock conveying equipment 61. The buffer device includes a base frame 1, with a tilting frame 2 hinged to the upper end of the base frame 1 via a hinge seat 11. One end of a tilting cylinder 21 is connected to the base frame 1, and the other end is connected to the tilting frame 2 to drive the tilting frame 2 to rotate. A stop block 22 is fixed at the rear end of the tilting frame 2 to prevent it from lying flat on the tilting frame. 2. The bar stock 6 on the upper surface falls from the rear end; on the left and right sides of the front end of the flipping frame 2, there are columns 3 fixed to the base frame 1; on the left and right sides of each column 3, vertical linear guide rails 31 connect to the slidable inbound picking plate 4 and outbound picking plate 5 respectively; the telescopic ends of the inbound cylinder 41 and the outbound cylinder 51 fixed to the base frame 1 are connected to the inbound picking plate 4 and the outbound picking plate 5 respectively, for controlling the lifting and lowering of the inbound picking plate 4 and the outbound picking plate 5 respectively; The upper end of the inbound material picking plate 4 is provided with a first inclined surface 42 with its lower end facing the stop block 22. A front inbound hook portion 43 and a rear inbound hook portion 44, respectively, are provided on the front and rear sides of the top of the inbound material picking plate 4, which are higher than the first inclined surface 42 and located in front of and behind the column 3. The upper end of the outbound material picking plate 5 is provided with a second inclined surface 52 with its upper end facing the stop block 22. A portion higher than the second inclined surface 52 and located in front of the column 3 is provided on the front side of the top of the outbound material picking plate 5. The outgoing hook part 53 is square; the rear side of the top of the second inclined surface 52 is located behind the column 3, and the distance D54 from the rear end of the column 3 is greater than the radius of the bar stock 6 and less than the diameter of the bar stock 6; the distance E45 from the front end of the inbound hook part 44 to the rear end of the column 3 is greater than the diameter of the bar stock 6 and less than 1.5 times the diameter of the bar stock 6; the hydraulic pump station 12 is connected to the pipeline of the tilting cylinder 21, the inbound cylinder 41 and the outbound cylinder 51 respectively, and is used to control their extension and retraction.

[0036] In use, in the initial state, both the inbound picking plate 4 and the outbound picking plate 5 are located below the top of the column 3; the high end of the flipping frame 2 faces forward and is lower than the top of the column 3.

[0037] When bar stock 6 is put into storage, as shown in the attached diagram, the following steps are included:

[0038] S1: First, the single bar stock 6 is transported to the front of the storage pick-up plate 4 and the storage pick-up hook 43. The bar stock 6 rolls backward along the first inclined surface 42 until it reaches the front of the top support column 3.

[0039] S2: The oil cylinder 41 extends and pushes the material picking plate 4 to rise until the bar 6 on the first inclined surface 42 exceeds the top of the column 3. Then the bar 6 rolls forward along the first inclined surface 42 until it reaches the top support after the material is picked up by the hook part 44.

[0040] S3: The warehousing cylinder 41 retracts, pulling the warehousing picking plate 4 down until the bar 6 on the first inclined surface 42 falls onto the upper end face of the tilting frame 2. The bar 6 slides along the inclined upper end face of the tilting frame 2 into the rear end of the tilting frame 2; warehousing is completed.

[0041] When bar stock 6 is released from the warehouse, as shown in the attached diagram, the following steps are included:

[0042] S4: The tilting cylinder 21 extends, driving the tilting frame 2 to rotate until its high end faces backward and its low end faces forward, so that the bar stock 6 laid flat on the tilting frame 2 slides forward until the rear end of the top support column 3 of the bar stock 6 at the front end.

[0043] S5: The outgoing cylinder 51 extends, pushing the outgoing material picking plate 5 to rise, so that the foremost bar 6 falls onto the second inclined surface 52.

[0044] S6: The material picker plate 5 continues to rise until the bar 6 on the second inclined plane 52 exceeds the top of the column 3. Then the bar 6 rolls forward along the second inclined plane 52 until it tops out of the material picker hook 53.

[0045] S7: The outgoing cylinder 51 retracts, the tilting cylinder 21 retracts, and the initial state is restored; the bar stock 6 located at the outgoing hook part 53 is transferred, and the outgoing process is completed.

[0046] As can be seen, during the outbound process, the outbound picking plate 5 works in conjunction with the column 3. Using the outbound picking plate 5, the bar stock 6 closest to the column 3 is picked up from among the multiple bars stock 6 laid flat on the tilting frame 2, and then this bar stock 6 is transferred to the front of the column 3, achieving single-bar outbound processing. The distance value D54 is greater than the radius of the bar stock 6, so the center of gravity of the bar stock 6 falls on the second inclined plane 52, which can push the bar stock 6 to rise. The distance value D54 is less than the diameter of the bar stock 6, ensuring that the outbound picking plate 5 can only pick up a single bar stock 6, preventing other bars stock 6 from being lifted, thus achieving the function of single-bar selection. The distance value E45 is greater than the diameter of the bar stock 6, ensuring that when the warehousing picker plate 4 descends, the distance from the front end of the picker hook 44 to the rear end of the column 3 is sufficient to accommodate one bar stock 6, preventing jamming. The distance value E45 is less than 1.5 times the diameter of the bar stock 6, ensuring that when the warehousing picker plate 4 descends, only one bar stock 6 is allowed to fall behind the column 3, thus achieving single-bar selection. Preferably, in this embodiment, the distance value D54 is equal to 1.2 times the radius of the bar stock 6, and the distance value E45 is equal to 1.2 times the diameter of the bar stock 6, resulting in more accurate and faster single-bar entry and exit.

[0047] To save space, the hydraulic pump station 12 is located in the middle of the base frame 1 and below the tilting frame 2, making the device compact and reducing the space occupied.

[0048] To accommodate longer bar stock 6, multiple tilting frames 2 are hinged to the base frame 1 and evenly spaced along the left-right direction. Each tilting frame 2 is connected to a tilting cylinder 21. The front end of each tilting frame 2 corresponds to a pair of uprights 3, and each upright 3 corresponds to an inbound picking plate 4 and an outbound picking plate 5. Each inbound picking plate 4 and each outbound picking plate 5 corresponds to an inbound cylinder 41 and an outbound cylinder 51, respectively. Therefore, multiple tilting frames 2 support the bar stock 6, extending the lifting and supporting portion in the left-right direction, making the bar stock 6 more stable. The number of tilting frames 2 can be adjusted according to the length of the bar stock 6.

[0049] To more precisely control the synchronous lifting and lowering of multiple material picking plates 4, a material picking plate 4 is fixedly connected to the rear side of a material picking plate 4. Each material picking plate 46 is meshed with a material picking gear 47, which is fixedly connected to a material picking shaft 48. The material picking shaft 48 is rotatably connected to the base frame 1 and is used to control the synchronous lifting and lowering of all the material picking plates 4.

[0050] Similarly, in order to more accurately control the synchronous lifting and lowering of multiple outgoing material picking plates 5, an outgoing rack 55 is fixedly connected to the rear side of the outgoing material picking plate 5; each outgoing rack 55 is meshed with an outgoing gear 56; the ingoing gear 47 is fixedly connected to the outgoing drive shaft 57, and the outgoing drive shaft 57 is rotatably connected to the base frame 1 for controlling the synchronous lifting and lowering of all the outgoing material picking plates 5.

[0051] Among them, the inbound drive shaft 48 and the outbound drive shaft 57 are at different heights and thus interfere with each other.

[0052] To facilitate individual material entry and exit counting, the base frame 1 is equipped with several displacement sensors 13 to monitor the rising and falling positions of the entry picking plate 4 and the exit picking plate 5. Although counting can also be achieved by monitoring the exit cylinder 51 and the entry cylinder, directly monitoring the entry and exit picking plates 4 is more direct and accurate.

[0053] The advantages of this utility model are: it solves the problem of single bar stock 6 entering and leaving the warehouse. The buffer device can store multiple bar stock 6. The bar stock is released out of the warehouse by the outgoing material picking plate 5 mechanism and sent to the buffer platform by the incoming material picking plate 4 mechanism. The mechanical replacement of manual labor in the inbound and outbound operations realizes the automated storage of bar stock 6, which saves time and labor. It can automatically count and count, and is not prone to errors.

[0054] The parts of this utility model not described in detail are prior art; for those skilled in the art, the technical features of the above embodiments can be combined in any way. In order to make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combination of these technical features does not contradict each other, they should be considered to be within the scope of this specification.
