Description

Technical Field

[0001] The present invention relates to the technical field of automated equipment, and more specifically, to an adjustable bar separation mechanism. Background Art

[0002] With the rapid development of the processing industry, enterprises pursue efficient, automatic, and environmentally friendly production methods. An important means is to use automated equipment to replace manual operations, improve production efficiency, and reduce labor costs. Due to the above advantages of automated equipment, they are currently widely used in material transportation.

[0003] A bar separation mechanism is a device used in the automated processing process to separate and transport bar-shaped materials according to predetermined requirements. The bar feeding mechanism disclosed in a Chinese patent with the publication number CN104477670B and the patent name "A bar feeding mechanism" includes a first material chamber, a second material chamber, a feeding roller, and a material trough; the feeding roller is arranged between the second material chamber and the material trough, and a communication channel is arranged between the first material chamber at a high position and the second material chamber at a low position. Through this channel, part of the bars in the first material chamber automatically fall into the second material chamber. The surface of the feeding roller is provided with grooves for accommodating a single bar; by rotating the feeding roller, the bar is fed from the second material chamber into the groove, and the groove drives the bar to rotate with the feeding roller and finally falls into the material trough; a pressing device is arranged above the material trough, and the pressing device is driven by a first power device to press down, limiting a single bar in the material trough; after the pressing device presses down, it covers the top opening of the material trough to form a cavity that only accommodates a single bar.

[0004] During the actual feeding process of the above bar feeding mechanism, after the bar enters the second material chamber, it will cover the space between the second material chamber and the feeding roller, and then fall into the groove of the rotating feeding roller and is driven by the feeding roller into the material trough. If bars with different diameters need to be transported, the grooves on the feeding roller can be opened with different diameters. At this time, it is easy for the grooves with a smaller diameter to be blocked by bars with a larger diameter, resulting in bars with a matching diameter being unable to fall in, causing the feeding roller to rotate idly. If the grooves are kept with the same diameter, when a bar with a smaller diameter falls into the groove, it cannot be effectively limited by the inner wall of the groove. After the feeding roller rotates and the orientation of the groove changes, the bar is very likely to break away from the groove before reaching the material trough. Therefore, the above bar feeding mechanism can only be used for the transportation of bars with a specific diameter and cannot be used for the transportation of bars with different diameters. In a production environment where bars with multiple diameters need to be processed, the production process cannot be flexibly adjusted, and the feeding mechanism needs to be frequently replaced, which not only reduces production efficiency but also increases production costs. Utility Model Content

[0005] In view of the above situation, in order to overcome the problem that the above-mentioned existing bar feeding mechanism can only be used for the conveying of bar materials of specific diameter, and cannot be used for the conveying of bar materials of different diameters, resulting in the inability to flexibly adjust the production process in a production environment where bar materials of multiple diameters need to be processed, and the feeding mechanism needs to be frequently replaced, which not only reduces production efficiency but also increases production costs. The purpose of the utility model is to provide a bar feeding mechanism that can meet the needs of conveying bar materials of different diameters, so that the production process can be flexibly adjusted according to needs, and there is no need to replace the feeding mechanism during production. Therefore, it has higher production efficiency and lower production cost.

[0028] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "left", "right", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product of the present invention is usually placed during use. It is only for the convenience of simplified description, rather than indicating or implying that such orientation is a specific orientation that must be possessed and specific orientation structures and operations. Therefore, it should not be construed as a limitation to the present invention.

[0030] Such as Figures 1 to 3 And Figures 7 to 9As shown in the figure, the utility model relates to an adjustable bar separation mechanism, which includes a frame 1, a feeding plate 2, a discharging plate 3, a gate opening and closing device 4, a gate adjusting device 5, a first power device 6 and a second power device 7. Among them, the top of the frame 1 has a gate 1a, and the gate 1a is vertically oriented as a whole. The feeding plate 2 and the discharging plate 3 are both fixed on the frame 1. The feeding plate 2 is located at the upper end of the gate 1a and slopes downward towards the gate 1a. The discharging plate 3 is located at the lower end of the gate 1a and slopes downward in a direction away from the gate 1a. The bars 8 to be separated and conveyed are placed on the feeding plate 2, roll along the feeding plate 2 under the action of gravity, and can fall into the gate 1a. After passing through the gate 1a, they are received by the feeding plate and finally roll along the feeding plate to be conveyed forward. Through slots 1b are opened on the front and rear sides of the gate 1a, and the through slots 1b communicate with the gate 1a. Both the gate opening and closing device 4 and the gate adjusting device 5 have two groups and are both arranged on the frame 1. The two gate opening and closing devices 4 are located on the front and rear sides of the gate 1a, and the two gate opening and closing devices 4 are opposite to the corresponding through slots 1b on the corresponding side. The gate adjusting device 5 is located on the left and right sides of the gate 1a and is connected to the gate opening and closing device 4. The first power device 6 and the second power device 7 are both arranged at the bottom of the frame 1. The output end of the first power device 6 is connected to the gate opening and closing device 4, and the output end of the second power device 7 is connected to the gate adjusting device 5. The gate opening and closing devices 4 on both sides of the gate 1a can be driven by the corresponding first power device 6 to rotate forward or backward. During the forward rotation, they slide along the through slot 1b synchronously and enter the gate 1a. After entering the gate 1a, they will eventually close it as the forward rotation continues. When the gate opening and closing device 4 rotates backward, it also slides along the through slot 1b and correspondingly exits the gate 1a to reopen the gate 1a. The gate adjusting device 5 is driven by the second power device 7 to move horizontally. The two gate opening and closing devices 4 will move towards or away from each other under the drive of the gate adjusting device 5, thereby changing the distance between them and correspondingly changing the diameter of the gate 1a. The bar separation mechanism of the utility model drives the two gate adjusting devices 5 to move horizontally by the second power device 7, and drives the two gate opening and closing devices 4 to move towards or away from each other, thereby changing the diameter of the gate 1a to allow bars 8 of different diameters to pass through. At the same time, the gate opening and closing device 4 can also rotate towards the inside of the gate 1a under the drive of the corresponding first power device 6 to close it, preventing the bars 8 on the feeding plate 2 from passing through the gate 1a and isolating them from the bars 8 that have entered the gate 1a, so that the bars 8 that have entered the gate 1a can be conveyed forward orderly through the discharging plate 3. Thus, the separation of bars 8 of different diameters is realized, and the distance between the bars 8 of different diameters separated each time can be correspondingly controlled, so that the production process can be flexibly adjusted according to needs during production, and there is no need to replace different feeding mechanisms during production. Therefore, it has high production efficiency and low production cost.

[0031] As Figures 2 to 4 and Figure 6 and Figure 7As shown, the gate opening and closing device 4 includes a rotating shaft 401, a profiling block 402 and a transmission assembly 403. The rotating shaft 401 is arranged horizontally, that is, arranged in a direction consistent with the length direction of the gate 1a. The profiling block 402 is arranged on the rotating shaft 401, and the profiling block 402 is slidably matched in the through groove 1b. It should be mentioned that there are two profiling blocks 402 corresponding to each group of gate opening and closing devices 4, and there are two corresponding through grooves 1b. The transmission assembly 403 is hinged to the rotating shaft 401 and the output end of the first power device 6, and the first power device 6 is connected to the The frame 1 is hinged, and the first power transfer first drives the transmission component 403 to transmit, and the power is transmitted to the rotating shaft 401 through the transmission component 403 to rotate the rotating shaft 401, and the rotating shaft 401 drives the connected profiling block 402 to rotate, so that the profiling block 402 can enter or exit the gate 1a, and slide in the corresponding through groove 1b during the rotation process. The gate adjustment device 5 is connected to the rotating shaft 401. When the gate adjustment device 5 is active, it drives the profiling block 402 to move horizontally through the rotating shaft 401, thereby changing the diameter of the gate 1a.

[0032] like Figures 2 to 4 as well as Figure 6 and Figure 7 As shown, the transmission assembly 403 includes a connecting rod 403a and a pull rod 403b, one end of the connecting rod 403a is hinged to the output end of the first power device 6, and the other end is hinged to the pull rod 403b, and the end of the pull rod 403b away from the connecting rod 403a is hinged on the rotating shaft 401. The first power device 6 first drives the connecting rod 403a to move horizontally, and converts the horizontal movement of the connecting rod 403a into rotational motion through the pull rod 403b, thereby driving the connected rotating shaft 401 to rotate, and the rotating shaft 401 drives the connected profiling block 402 to rotate. When the gate adjustment device 5 drives the rotating shaft 401 to move, the pull rod 403b will rotate at the same time, thereby avoiding interference with the movement of the rotating shaft 401.

[0033] like Figure 2 As shown, the gate opening and closing device 4 also includes a large tightening sleeve 404 and a small tightening sleeve 405, which are sequentially sleeved on the connecting rod 403a, and the large tightening sleeve 404 is connected to the pull rod 403b, specifically, it is connected to the pull rod 403b through two threaded fasteners, the small tightening sleeve 405 can prevent the rotating shaft 401 from generating translational movement along the length direction, ensuring the stable connection between the rotating shaft 401 and the gate adjusting device 5, and the large tightening sleeve 404 ensures that the pull rod 403b is stably connected to the rotating shaft 401 to avoid dislocation.

[0034] like Figure 2 , Figure 3 , Figure 8 and Figure 9As shown, the gate adjusting device 5 includes a top block 501, a top rod 502, a slider 503 and a slide rail 504. The top block 501 is connected to the output end of the second power device 7. The top rod 502 is arranged on the top block 501. There are two groups of sliders 503. The two sliders 503 are correspondingly connected to the two gate opening and closing devices 4, and are both connected to the top rod 502 and are both slidably fitted in the slide rail 504. The slide rail 504 is arranged on the frame 1. Here, it should be mentioned that the second power device 7 is vertically installed on the frame 1, and the slide rail 504 is horizontally installed on the frame 1. When adjusting the diameter of the gate 1a, the second power device 7 first drives the top block 501 to move up and down in the direction perpendicular to the horizontal plane. During the up and down movement of the top block 501, the top rod 502 will be pushed. The top rod 502 drives the slider 503 to move up and down along the slide rail 504. The two gate opening and closing devices 4 are driven by the slider 503 to move horizontally, realizing the adjustment of the diameter of the gate 1a. In the present utility model, the sliders 503 connected by the two groups of gate adjusting devices 5 always move horizontally in opposite directions, so that the two gate opening and closing devices 4 can move towards or away from each other smoothly, and better change the diameter of the gate 1a.

[0035] As Figure 5 shown, the gate adjusting device 5 further includes a cylindrical pin 505. One end of the cylindrical pin 505 is fixed on the top rod 502. An inclined chute 503a is formed on the slider 503. The other end of the cylindrical pin 505 is slidably fitted in the inclined chute 503a. Based on the above settings, the horizontal movement of the slider 503 along the slide rail 504 is mainly realized by driving the cylindrical pin 505. When the cylindrical pin 505 moves up and down under the drive of the second power device 7 through the top block 501 with the top rod 502, it can exert pressure on the inclined inner wall of the inclined chute 503a. The existence of the inclined chute 503a enables the slider 503 to move relative to the cylindrical pin 505 under the action of pressure. Guided by the slide rail 504, the slider 503 finally moves horizontally, thereby driving the two gate opening and closing devices 4 to move, realizing the adjustment of the diameter of the gate 1a.

[0036] As Figure 2 and Figure 3As shown in the figure, the frame 1 includes a bottom plate 101, a machine table 102, support columns 103, mounting seats 104, a partition plate 105, a front baffle 106 and a rear baffle 107. The support columns 103 are arranged at the bottom of the machine table 102. There are multiple groups of support columns 103, which provide stable support for the machine table 102. Each support column 103 is fixed on the bottom plate 101. There are two groups of mounting seats 104, and the two mounting seats 104 are arranged on the left and right sides of the top of the machine table 102. There is a spacing between the two mounting seats 104. The partition plate 105 is correspondingly installed on the front baffle 106 and the rear baffle 107. The front baffle 106 and the rear baffle 107 are arranged on both sides of the partition plate 105 and are mounted on the mounting seats 104. A gate 1a is formed between the front baffle 106 and the rear baffle 107. Through grooves 1b are opened on the front baffle 106 and the rear baffle 107. The feeding plate 2 is arranged on the top of the front baffle 106. The discharging plate 3 is arranged in the spacing between the two mounting seats 104. It should be mentioned that the first power device 6 and the second power device 7 are arranged on the bottom plate 101. Two groups of gate opening and closing devices 4 are arranged on the outer sides of the front baffle 106 and the rear baffle 107. The slide rail 504 of the gate adjusting device 5 is arranged on the outer side wall of the mounting seat 104.

[0037] Further, the first power device 6 and the second power device 7 are oil cylinders or air cylinders, so that the corresponding gate opening and closing devices 4 and the gate adjusting device 5 can be driven to move through the reciprocating movement of their respective output ends.

[0038] Combined Figures 1 to 9, when the bar separating mechanism of the present utility model is used in actual production, the bar 8 to be separated and conveyed is placed on the feeding plate 2. Under the action of gravity, the bar 8 will roll along the feeding plate 2 and fall into the gate 1a. It falls through the gate 1a to the feeding plate, is received by the feeding plate, and finally rolls along the feeding plate to be conveyed forward. If bars 8 with different diameters need to be separated, the second power device 7 can be operated. The output end of the second power device 7 first drives the top block 501 of the gate adjusting device 5 to move up and down. The top block 501 drives the ejector rod 502 to move up and down. The ejector rod 502 pushes the slider 503 to move horizontally along the slide rail 504 through the cylindrical pin 505, thereby driving the synchronous movement of the rotating shaft 401 of the connected gate opening and closing device 4. The two gate opening and closing devices 4 maintain opposite moving directions, so that the profiling blocks 402 on their respective rotating shafts 401 move away from or towards each other along the through groove 1b, thereby changing the diameter of the gate 1a and allowing bars 8 with different diameters to pass through. At the same time, the two gate opening and closing devices 4 can also be driven by the corresponding first power device 6. The connecting rod 403a is driven to rotate through the pull rod 403b, and then the rotating shaft 401 is driven to rotate by the connecting rod 403a, so that the profiling blocks 402 of each other rotate towards and away from each other. When rotating towards the inside of the gate 1a to a certain angle, the gate 1a is closed to prevent the bar 8 on the feeding plate 2 from passing through the gate 1a and isolating it from the bar 8 that has entered the gate 1a, so that the bar 8 that has entered the gate 1a can be conveyed forward through the discharging plate 3 in an orderly manner, thereby changing the distance between the bars 8 with different diameters separated each time.

[0039] The above embodiments and descriptions in the specification only illustrate the principles and the best embodiments of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
