Description

Technical Field

[0001] The utility model relates to a roller conveying mechanism. Background Art

[0002] Roller conveyor mechanisms are also commonly referred to as drum conveyor mechanisms. The motor drives the rotation of the drum to move the material on the drum. This type of conveying mechanism is usually used to transport materials with heavy weights because the drum has strong supporting strength. A defect of the roller conveyor mechanism is that it is difficult to turn. Since the drum needs to transmit power through a power transmission belt, the drums are usually required to be parallel to each other. Therefore, the roller conveyor mechanism can usually only realize material transportation in a straight line. In the production workshop, due to the limited space of the production workshop, the production line cannot be built in a straight line, which also means that the roller conveyor mechanism corresponding to the production line needs to be able to turn. In the prior art, the turning of the roller conveyor mechanism is usually achieved by setting the drum in one direction on a lifting frame, and the lifting of this lifting frame usually uses a cylinder or an oil cylinder as a power. On the other hand, since the materials transported by the roller conveyor mechanism are usually heavy, the material conveying surface for conveying the materials cannot usually be configured too high. If the roller position is set too high, there is a greater safety risk of material falling, and it is also inconvenient for the staff to get on and off the materials. The lifting frame powered by a cylinder or an oil cylinder usually requires a higher height. Summary of the invention

DETAILED DESCRIPTION

[0021] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0022] Figure 1An example of a roller conveying mechanism with steering is provided, which includes a conveying mechanism in two directions and a conveying steering adapter mechanism 3. The conveying mechanisms in the two directions are respectively a first direction conveying mechanism 1 and a second direction conveying mechanism 2. The conveying mechanisms in the two directions are both provided with conveying roller mechanisms, and the material conveying surface levels of the conveying mechanisms in the two directions are different. Specifically in this embodiment, the material conveying surface level of the second direction conveying mechanism 2 is higher than the material conveying surface of the first direction conveying mechanism 1, and the material conveying directions of the first direction conveying mechanism 1 and the second direction conveying mechanism 2 are perpendicular. The conveying steering adapter mechanism 3 is arranged at the connection between the first direction conveying mechanism 1 and the second direction conveying mechanism 2, and is respectively connected to the conveying mechanisms in the two directions in two directions. The conveying steering adapter mechanism 3 includes two sets of conveying roller mechanisms. The two sets of conveying roller mechanisms are respectively a first conveying roller mechanism 31 and a second conveying roller mechanism 32. The first conveying roller mechanism 31 and the second conveying roller mechanism 32 are respectively equipped with power mechanisms. Specifically, the first conveying roller mechanism 31 is connected to the first power mechanism 311, and the second conveying roller mechanism 32 is connected to the second power mechanism 321. The two sets of conveying roller mechanisms are connected to the conveying mechanisms in two directions respectively. Specifically, the first conveying roller mechanism 31 is connected to the first direction conveying mechanism 1; the second conveying roller mechanism 32 is connected to the second direction conveying mechanism 2. Figure 2 and Figure 3 , the first conveying roller mechanism 31 is fixed on the frame of the conveying steering adapter mechanism 3, and has the same material conveying surface height as the conveying mechanism with a lower material conveying surface height, and is connected thereto. Specifically in this embodiment, the conveying mechanism with a lower material conveying surface height is the first direction conveying mechanism 1. That is, the first conveying roller mechanism 31 has the same material conveying surface height as the first direction conveying mechanism 1, and the first conveying roller mechanism 31 is connected to the first direction conveying mechanism 1. The second conveying roller mechanism 32 is arranged on the low-height short-stroke lifting mechanism 300, and more specifically, the second conveying roller mechanism 32 is arranged on the lifting frame 33 of the low-height short-stroke lifting mechanism 300.

[0023] Low height short stroke lifting mechanism 300, refer to Figure 3 and Figure 4, including a lifting frame 33 and a lifting mechanism 34 connected to the lifting frame 33. The lifting frame 33 can be lifted vertically under the limitation and guidance of the four sides of the frame of the conveying steering adapter mechanism 3. The lifting mechanism 34 includes a roller 331 arranged at the bottom of the lifting frame 33, a translation lifting guide frame and a lifting drive cylinder 342. The translation lifting guide frame includes a translation lifting slide 341 arranged in a slide slot and a lifting drive cylinder 342 connected to the translation lifting slide 341. Horizontally arranged. The lifting drive cylinder 342 can be a cylinder or an oil cylinder. Specifically in this embodiment, the lifting drive cylinder 342 preferably adopts a cylinder. The lifting drive cylinder 342 is horizontally arranged, that is, the piston of the lifting drive cylinder 342 moves horizontally, thereby enabling the translation lifting slide 341 connected to the lifting drive cylinder 342 to move horizontally in the slide slot along the length direction of the translation lifting slide 341 under the drive of the lifting drive cylinder 342. The translation lifting slide 341 is provided with an inclined groove 3411. The roller 331 is arranged at the bottom of the lifting frame 33 through the roller seat 332, and a bearing is arranged between the roller 331 and the roller seat 332, so that the roller 331 can rotate along the axis of the horizontal axis. The axis of the roller 331 is horizontal and perpendicular to the length direction of the translation lift slide 341. The position of the roller 331 matches the position of the inclined groove 3411, so that when the translation lift slide 341 moves horizontally, the roller 331 can roll into the inclined groove 3411 or move out of the inclined groove 3411. Figure 5 When the translation lifting slide 341 moves in the direction indicated by the arrow M under the drive of the lifting drive cylinder 342, the roller 331 in the inclined groove 3411 can roll along the inclined surface of the inclined groove 3411 and finally roll out of the inclined groove 3411. In this process, the translation lifting slide 341 has a lifting effect on the roller 331, and when the roller 331 rolls out of the inclined groove 3411, it lifts the lifting frame 33 above the roller 331 to the highest point; when the translation lifting slide 341 is in the lifting When driven by the driving cylinder 342 to move in the direction opposite to the direction indicated by the arrow M, the roller 331 outside the inclined groove 3411 can roll along the inclined surface of the inclined groove 3411 and roll into the inclined groove 3411, and finally roll to the lowest point of the inclined groove 3411. During this process, the lifting frame 33 above the roller 331 naturally falls under the action of its own gravity, so that the lifting frame 33 is lowered. When the roller 331 rolls to the lowest point of the inclined groove 3411, the lifting frame 33 drops to the lowest point.

[0024] When the lifting frame 33 is lifted to the highest point, the material conveying surface height of the second conveying roller mechanism 32 provided on the lifting frame 33 is higher than the material conveying surface height of the first conveying roller mechanism 31 fixed on the frame, and is the same as the material conveying surface height of the conveying mechanism with a higher material conveying surface height, so that the second conveying roller mechanism 32 on the lifting frame 33 is connected with the conveying mechanism with a higher material conveying surface height. In this embodiment, the conveying mechanism with a higher material conveying surface height is the second direction conveying mechanism 2. That is to say, when the lifting frame 33 is lifted to the highest point, the material conveying surface height of the second conveying roller mechanism 32 is flush with the second direction conveying mechanism 2, and thus, the second conveying roller mechanism 32 is connected with the second conveying mechanism 2.

[0025] The working principle of this embodiment is as follows: when the second conveying roller mechanism 32 is lowered to the lowest point, the height of the second conveying roller mechanism 32 is lower than the height of the first conveying roller mechanism 31. At this time, through the connection between the first conveying roller mechanism 31 and the first direction conveying mechanism 1, the materials on the first direction conveying mechanism 1 can be moved to the conveying steering adapter mechanism 3, and the materials on the conveying steering adapter mechanism 3 can also be moved to the first direction conveying mechanism 1. The second conveying roller mechanism 32 with a height lower than the first conveying roller mechanism 31 will not hinder the material transportation between the conveying steering adapter mechanism 3 and the first direction conveying mechanism 1. When the second conveying roller mechanism 32 is lifted to the highest point, the height of the second conveying roller mechanism 32 is higher than the height of the first conveying roller mechanism 31. At this time, through the connection between the second conveying roller mechanism 32 and the second direction conveying mechanism 2, the materials on the second direction conveying mechanism 2 can be moved to the conveying steering adapter mechanism 3, and the materials on the conveying steering adapter mechanism 3 can also be moved to the second direction conveying mechanism 2. The first conveying roller mechanism 31 with a height lower than the second conveying roller mechanism 32 will not hinder the material transportation between the conveying steering adapter mechanism 3 and the second direction conveying mechanism 2. When the material needs to be transferred from the first direction conveying mechanism 1 to the second direction conveying mechanism 2, the second conveying roller mechanism 32 is first lowered to the lowest point, and then the material is moved from the first direction conveying mechanism 1 to the conveying steering adapter mechanism 3. At this time, the material on the conveying steering adapter mechanism 3 is supported by the first conveying roller mechanism 31, and then the second conveying roller mechanism 32 is lifted to the highest point, so that the material is supported by the second conveying roller mechanism 32, and finally the material on the conveying steering adapter mechanism 3 is conveyed to the second direction conveying mechanism 2. When the material needs to be transferred from the second direction conveying mechanism 2 to the first direction conveying mechanism 1, the specific process is opposite to the above, and will not be repeated.

[0026] In addition, in order to enable the second conveying roller mechanism 32 to achieve smooth lifting and lowering, in this embodiment, two translation lifting slide plates 341 are provided, and two inclined grooves 3411 are arranged on the translation lifting slide plate 341. The two translation lifting slide plates 341 are parallel to each other and are respectively located below the two sides of the lifting frame 33. The two translation lifting slide plates 341 are connected through the synchronous translation frame 343, and are connected to the lifting drive cylinder 342 through the synchronous translation frame 343.

[0027] In another optional embodiment, three, four or more translation lift slide plates 341 may be provided. Three, four or more inclined grooves 3411 may be provided on the translation lift slide plate 341. In this case, the translation lift slide plates 341 are parallel to each other, and the translation lift slide plates 341 are connected by a synchronous translation frame 343.

[0028] In addition, in order to reduce friction when the translation lift plate 341 translates in the slide groove, the translation lift plate 341 is mounted on a rolling mechanism. Figure 4 , the slide groove is constructed by a roller groove bracket 344; the roller groove bracket 344 includes a bracket plate 3441 and a rolling rod 3442. There are two bracket plates 3441. The two bracket plates 3441 are vertically arranged, parallel to each other, and arranged along the length direction of the translational lifting slide plate 341. A certain gap is left between the two bracket plates 3441. The rolling rod 3442 is arranged between the two bracket plates 3441. The rolling rod 3442 and the bracket plate 3441 are connected by a bearing. When the translational lifting slide plate 341 is arranged on the roller groove bracket 344, the bottom of the translational lifting slide plate 341 is mounted on the rolling rod 3442, supported by the rolling rod 3442, and clamped by the two bracket plates 3441. It should be noted that, in this embodiment, the slideway is constructed by two roller slot brackets 344, which are respectively arranged at the two ends of the length direction of the translation jacking slide plate 341, and each roller slot bracket 344 is equipped with two rolling round rods 3442. It is understood by those skilled in the art that the roller slot brackets 344 that form the slideway can also be three, four or more, or even one. Obviously, when there is one roller slot bracket 344 that forms the slideway, at least two rolling round rods 3442 on the roller slot bracket 344 are required.

[0029] In another optional embodiment, the slide groove can realize the rolling movement of the translation lifting slide plate 341 through two mutually parallel bracket plates cooperating with balls.

[0030] In addition, in order to reduce the power of the lifting drive cylinder 342 required for the lifting of the lifting frame 33, the angle between the inclined surface of the inclined surface groove 3411 and the horizontal is generally not more than 30 degrees.
