Description

Technical Field

[0001] This utility model relates to the field of profile conveying technology, and in particular to a material distribution and conveying device for a material rack and a material rack including the material distribution and conveying device. Background Technology

[0002] A material rack is provided, which has an inclined feeding surface, a blocking device, and a lifting device. Profiles are placed on the inclined feeding surface and move downwards along the surface under gravity until they are blocked by the blocking device. After the profile is blocked, the lifting device pushes the profile closest to the blocking device upwards, allowing it to pass over the blocking device and continue to be conveyed.

[0003] In this type of material rack, the feeding surface is inclined, but the blocking surface of the blocking device is vertical, and the pushing direction of the lifting device is also vertical. With this configuration, when several profiles are arranged sequentially on the feeding surface, if the lifting device wants to push the profile closest to the blocking device upwards, it needs to overcome not only the weight of the profile closest to the blocking device, but also the downward pressure exerted by other profiles on the feeding surface. This increases the work done by the lifting device, making it prone to damage after repeated operation and resulting in a shorter service life. Utility Model Content

[0004] The main purpose of this utility model is to propose a material distribution and conveying device for a material rack, which aims to solve the technical problem that the material feeding device in the prior art is easily damaged.

[0005] To achieve the above objectives, this utility model proposes a material distribution and conveying device for a material rack, including a conveying frame with an inclined conveying surface; it also includes a baffle and a top-loading device. The baffle is located on the conveying frame and at least partially protrudes from the conveying surface. The baffle has a baffle surface that is angled to the conveying surface and is inclined from top to bottom in a front-to-back direction. The top-loading device includes a top-loading drive device and a top-loading component that are connected by a transmission. The top-loading drive device is located on the conveying frame, and the top-loading component is positioned corresponding to the baffle surface. The top-loading drive device can drive the top-loading component to move in a direction parallel to the baffle surface, lifting the profile closest to the baffle surface and causing it to pass over the baffle.

[0006] The beneficial effects of this utility model are as follows: the retaining surface is perpendicular to the conveying surface, and the top material driving device can drive the top material to move in a direction parallel to the retaining surface. When a profile is conveyed along the conveying surface to the side of the retaining surface, the top material device lifts the profile closest to the retaining surface in a direction parallel to the retaining surface. During this process, the top material driving device is less affected by other profiles behind it. Therefore, most of its work can be used to lift the target profile, which is conducive to the long-term operation of the top material device, reduces the maintenance frequency of the top material device, and extends the service life of the top material device and the material conveying device.

[0007] Preferably, the material distribution and conveying device further includes an adjusting device, which includes an adjusting drive device and an adjusting slide rail. The adjusting slide rail is mounted on the conveying frame and its extension direction is parallel to the conveying direction of the conveying surface. The top material device is mounted on the adjusting slide rail and can slide along the adjusting slide rail. The output end of the adjusting drive device is connected to the top material device for transmission, so as to drive the top material device to slide along the adjusting slide rail. This is beneficial to expanding the application range of the material distribution and conveying device, thereby improving the conveying efficiency and reducing the production cost.

[0008] Preferably, the baffle surface is further provided with a buffer curved surface, the rear side of which is connected to the upper side of the baffle surface, and the front side of which is connected to the conveying surface. The buffer curved surface bends upward and extends downward in the direction from back to front, which is beneficial for protecting the profile and the conveying frame.

[0009] Preferably, the top material component includes a top material end and a front inclined surface, the front inclined surface is located on the front side of the top material component, and the rear side of the front inclined surface is connected to the top material end.

[0010] Preferably, the top material component also includes a rear inclined surface located at its rear side, the front side of which is connected to the top material end, which is beneficial for protecting the pipe and the conveying component.

[0011] Preferably, the front and rear sides of the top material end are respectively provided with front curved surfaces, the front side of the front curved surface is connected to the front inclined surface, the front curved surface bends downward and extends downward in the direction from back to front, which is beneficial to extend the service life of the top material component, the top material device and the material distribution and conveying device.

[0012] Preferably, the conveyor frame is also provided with a stopping component, which includes a stopping plate and a buffer plate. The stopping plate is vertically located at the end of the conveyor frame and at least partially protrudes from the conveying surface. The buffer plate is provided with a buffer slope that slopes from top to bottom in a front-to-back direction. The front side of the buffer slope is connected to the rear side of the stopping plate, and the rear side of the buffer slope is connected to the conveying surface, which is beneficial for protecting the profile and the stopping plate.

[0013] Preferably, the conveyor frame is also provided with a horizontally arranged profile placement surface, the front side of which is connected to the rear side of the conveying surface. This helps to reduce the initial speed of the profile conveyed along the conveying surface, thereby reducing the collision force between the profile and the retaining surface or the front profile, which helps to protect the profile and the material distribution and conveying device.

[0014] This utility model also proposes a material rack, including the material distribution and conveying device of the above-mentioned material rack.

[0015] Preferably, the material distribution and conveying device further includes an adjusting device, which includes an adjusting drive device and an adjusting slide rail. The adjusting slide rail is mounted on the conveying frame and its extension direction is parallel to the conveying surface. The top material device is mounted on the adjusting slide rail and can slide along the adjusting slide rail. The output end of the adjusting drive device is connected to the top material device for transmission, so as to drive the top material device to slide along the adjusting slide rail. The material frame includes a synchronous transmission structure and multiple material distribution and conveying devices arranged side by side. The adjusting drive devices on the multiple material distribution and conveying devices are interconnected through the synchronous transmission structure so that the top material devices on the multiple material distribution and conveying devices move synchronously.

[0023] like Figures 1 to 3 , Figures 5 to 8As shown, a material distribution and conveying device for a material rack includes a conveying frame 1 with an inclined conveying surface 11; it also includes a baffle 2 and a top-loading device 3. The baffle 2 is disposed on the conveying frame 1 and at least partially protrudes from the conveying surface 11. The baffle 2 has a baffle surface 21, which is angled to the conveying surface 11 and is inclined from top to bottom in a front-to-back direction. The top-loading device 3 includes a top-loading drive device 31 and a top-loading member 32 connected by a transmission. The top-loading drive device 31 is disposed on the conveying frame 1, and the top-loading member 32 is positioned corresponding to the baffle surface 21. The top-loading drive device 31 can drive the top-loading member 32 to move in a direction parallel to the baffle surface 21, lifting the profile 10 closest to the baffle surface 21 and making it pass over the baffle 2.

[0024] The retaining surface 21 is perpendicular to the conveying surface 11, and the top material drive device 31 can drive the top material 32 to move in a direction parallel to the retaining surface 21. When a profile 10 is conveyed along the conveying surface 11 to a position close to the retaining surface 21, the top material drive device 3 lifts the profile 10 closest to the retaining surface 21 in a direction parallel to the retaining surface 21. During this process, the top material drive device 31 is less affected by other profiles 10 on the rear side, so most of its work can be used to lift the target profile 10, which is beneficial for the top material drive device 3 to work for a long time, reduce the maintenance frequency of the top material drive device 3, and extend the service life of the top material drive device 3 and the material conveying device.

[0025] In this embodiment, the top material drive device 31 includes a cylinder, and the top material component 32 is disposed on the piston rod of the cylinder.

[0026] In some specific embodiments, reference is made to Figure 7 and Figure 8 The angle α between the conveyor 11 and the horizontal plane is 20°, and the angle b between the retaining surface 21 and the conveyor surface is 90°~150°.

[0027] Specifically, refer to Figure 8 The material blocking surface 21 is perpendicular to the conveying surface 11, i.e., b is 90°. This setting can ensure that the profile 10 is stopped while reducing the burden on the material lifting device 3.

[0028] In some specific embodiments, reference is made to Figure 1 and Figure 2 The material conveying device also includes an adjusting device 4, which includes an adjusting drive device 41 and an adjusting slide rail 42. The adjusting slide rail 42 is mounted on the conveying frame 1 and its extension direction is parallel to the conveying direction of the conveying surface 11. The top material device 3 is mounted on the adjusting slide rail 42 and can slide along the adjusting slide rail 42. The output end of the adjusting drive device 41 is connected to the top material device 3 to drive the top material device 3 to slide along the adjusting slide rail 42.

[0029] Specifically, in this embodiment, the adjustment drive device 41 includes a hand crank 411 and an adjustment transmission structure 412. The adjustment transmission structure 412 can be a gear and rack mechanism or other mechanism, as long as it can convert rotation into linear motion.

[0030] In this embodiment, the adjusting device 4 can move in a direction parallel to the conveying direction of the conveying surface 11 to adjust the relative position between the top material member 32 and the stop surface 21, so that the top material member 32 can lift profiles 10 of different widths / diameters. This is beneficial to expanding the application range of the material distribution and conveying device, thereby improving conveying efficiency and reducing production costs. Since the top material member 3 needs to be adjusted relatively infrequently in actual production, the adjusting drive device 41 adopts a simple and low-cost hand crank 411, which is beneficial to reducing production costs and also to making the material rack lightweight, facilitating transportation and installation.

[0031] In some specific embodiments, reference is made to Figure 1 and Figure 2 The baffle surface 21 is also provided with a buffer surface 22. The rear side of the buffer surface 22 is connected to the upper side of the baffle surface 21, and the front side of the buffer surface 22 is connected to the conveying surface 11. The buffer surface 22 is curved upward and extends downward in the direction from back to front.

[0032] In this embodiment, "the buffer surface 22 bends upward and extends downward in the direction from back to front" means that the buffer surface 22 is arched upward as a whole, with its highest point located at the position connected to the stop surface 21 and its lowest point located at the position connected to the conveying surface 11, and it extends continuously downward in the direction from front to back. This arrangement ensures that after the profile 10 passes the stop surface 21, it will move a certain distance along the buffer surface 22 before falling onto the conveying surface 11, rather than directly hitting the conveying surface 11. This helps protect the profile 10 and the conveyor frame 1. Moreover, due to the upward arch of the buffer surface 22, the profile 10 will not move too fast when it moves to the conveying surface 11, avoiding excessive collision between the profile 10 and subsequent structures, further protecting the profile 10.

[0033] In some specific embodiments, reference is made to Figure 3 The top material component 32 includes a top material end 323 and a front inclined surface 321. The front inclined surface 321 is located on the front side of the top material component 32, and the rear side of the front inclined surface 321 is connected to the top material end 323.

[0034] The top-feeding component 32 in this embodiment is particularly suitable for pipes or profiles 10 with a circular cross-section. Taking pipes as an example: before material distribution, multiple pipes on the conveying surface 11 are arranged sequentially behind the retaining surface 21; during material distribution, the adjusting device 4 aligns the top-feeding end 323 between the first and second pipes closest to the retaining surface 21, and then the top-feeding device 3 pushes upwards, lifting the first pipe closest to the retaining surface 21. During the lifting process, refer to... Figure 5 When the front inclined surface 321 of the top material member 32 does not protrude beyond the stop surface 21 of the stop member 2, the pipe is limited by the front inclined surface 321 of the top material member 32 and the stop surface 21 of the stop member 2, and therefore will only move upward along the extension direction of the stop surface; Reference Figure 6 When the front inclined surface 321 of the top material component 32 gradually protrudes beyond the blocking surface 21 of the blocking component 2, the front inclined surface 321 of the top material component 32 will push the pipe forward until the pipe passes the blocking surface 21. Then the pipe will roll along the buffer curved surface 22 and finally fall on the conveying surface 11 of the conveying frame 1.

[0035] In the above-mentioned material sorting process, "the top end 323 is aligned between the first and second pipes closest to the retaining surface 21" means that the position of the top end 323 is located between the center of the first pipe and the center of the second pipe closest to the retaining surface 21. Most preferably, the top end 323 is aligned exactly with the contact position between the first and second pipes closest to the retaining surface 21. Generally speaking, the pipes to be sorted in the same batch have the same specifications, so it can also be said that the top end 323 is aligned exactly with the midpoint of the line connecting the center of the first pipe and the center of the second pipe closest to the retaining surface 21.

[0036] In some specific embodiments, reference is made to Figure 3 The top material component 32 also includes a rear inclined surface 322 located on its rear side, and the front side of the rear inclined surface 322 is connected to the top material end 323.

[0037] During the ejection process, the adjusting device 4 may not be properly adjusted, causing the ejector 32 to lift the second pipe closest to the baffle surface 21. In this embodiment, the rear inclined surface 322 of the ejector 32 is designed to ensure that, in the event of this, the second pipe closest to the baffle surface 21 can fall back onto the conveyor surface 11 along the rear inclined surface 322 of the ejector 32, thus preventing it from directly hitting the conveyor frame 1 or other pipes behind it, protecting both the pipe and the conveyor components.

[0038] In some specific embodiments, reference is made to Figure 3 The front side of the top material end 323 is provided with a front curved surface 3211. The front side of the front curved surface 3211 is connected to the front inclined surface 321. The front curved surface 3211 is bent downward and extends downward in the direction from back to front.

[0039] In this embodiment, the front curved surface 3211 is designed to make the ejector 32 better match the outer surface of the pipe or the profile 10 with a circular cross-section during the ejection process. This can partially "wrap" the pipe, increase the contact area between the pipe and the ejector 32, and prevent the pressure from the pipe on the ejector 32 from being concentrated in a small area. This slows down the wear rate of the ejector 32 and helps extend the service life of the ejector 32, the ejector device 3, and the material conveying device.

[0040] Furthermore, a rear curved surface 3221 is provided on the rear side of the top material end 323. The rear side of the rear curved surface 3221 is connected to the rear inclined surface 322. The rear curved surface 3221 bends downward and extends downward in the front-to-back direction. The purpose of the rear curved surface 3221 is similar to that of the front curved surface 3211, to further reduce the wear rate of the top material 32.

[0041] Furthermore, the upper side of the die end is rounded to prevent it from being too sharp and damaging the profile 10.

[0042] In some specific embodiments, reference is made to Figure 1 and Figure 2 The conveyor frame 1 is also provided with a stopping component 5, which includes a stopping plate 51 and a buffer plate 52. The stopping plate 51 is vertically located at the end of the conveyor frame 1 and at least partially protrudes from the conveying surface 11. The buffer plate 52 is provided with a buffer slope 521, which slopes from top to bottom in the direction from front to back. The front side of the buffer slope 521 is connected to the rear side of the stopping plate 51, and the rear side of the buffer slope 521 is connected to the conveying surface 11.

[0043] In this embodiment, the stop plate 51 is used to stop the profile 10 so that it can be moved to the subsequent processing equipment. The buffer plate 52 is provided to reduce the moving speed of the profile 10 as it plunges down from the conveyor surface 11, thereby reducing the collision force between the profile 10 and the stop plate 51, which helps protect the profile 10 and the stop plate 51. The profile 10 finally stops at the junction of the buffer plane and the conveyor surface 11.

[0044] In some specific embodiments, reference is made to Figure 1 The conveyor frame 1 is also provided with a horizontally arranged profile placement surface 12, the front side of which is connected to the rear side of the conveyor surface 11.

[0045] Since the profile 10 has a certain initial velocity when it is transported from the front equipment to the conveyor frame 1, if it is directly transported to the inclined conveyor surface 11, the profile 10 will collide with the baffle surface 21 or the profile 10 in front at a relatively high speed, which will easily cause damage.

[0046] In this embodiment, the conveyor frame 1 is also provided with a horizontally arranged profile placement surface 12. When the profile 10 is conveyed from the front equipment to the conveyor frame 1, it is first conveyed to the profile placement surface 12. Under the action of friction between the profile 10 and the conveyor frame 1, the profile 10 will stop on the profile placement surface 12. When a profile 10 is conveyed to the profile placement surface 12 from the rear, the profile 10 from the front will move forward until enough profiles 10 are conveyed from the rear. Only then will the foremost profile 10 move along the conveyor surface 11. The profile placement surface 12 helps to reduce the initial speed of the profile 10 conveyed along the conveyor surface 11, thereby reducing the collision force between the profile 10 and the stop surface 21 or the front profile 10, which helps to protect the profile 10 and the material distribution and conveying device.

[0047] refer to Figure 4 This embodiment also proposes a material rack, including the material distribution and conveying device of the above-mentioned material rack.

[0048] In some specific embodiments, reference is made to Figure 4 The material distribution and conveying device also includes an adjusting device 4, which includes an adjusting drive device 41 and an adjusting slide rail 42. The adjusting slide rail 42 is mounted on the conveying frame 1 and its extension direction is parallel to the conveying surface 11. The top material device 3 is mounted on the adjusting slide rail 42 and can slide along the adjusting slide rail 42. The output end of the adjusting drive device 41 is connected to the top material device 3 to drive the top material device 3 to slide along the adjusting slide rail 42. The material frame includes a synchronous transmission structure 20 and multiple material distribution and conveying devices arranged side by side. The adjusting drive devices 41 on the multiple material distribution and conveying devices are interconnected through the synchronous transmission structure 20 so that the top material devices 3 on the multiple material distribution and conveying devices move synchronously.

[0049] Specifically, the material distribution and conveying devices located at both ends of the material rack include at least one adjustment drive device 41 with a hand crank 411. The adjustment drive device 41 includes a drive shaft, and the hand crank 411 is connected to the adjustment transmission structure 412 of multiple material distribution and conveying devices through the drive shaft, thereby enabling multiple top material devices 3 to move synchronously.

[0050] In some other embodiments, each material conveying device is equipped with a handwheel 411 for adjusting the position of the top material device 3 by means of the handwheel 411.

[0051] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
