Description

Technical Field

[0001] This invention relates to the field of conveying equipment technology, and in particular to a differential turning conveying device and a turning conveyor line. Background Technology

[0002] For flat products such as boards, decorative panels, and tiles, they are laid flat on the conveyor line for transport during the production line process. Due to space constraints, it is generally difficult to arrange the equipment in a straight line, so a curved conveyor line is needed to change the direction of material transport during production.

[0003] Traditional turning conveyor lines change the conveying direction by connecting two conveyor lines. While the product's conveying direction changes, its original orientation remains the same. An additional mechanism is needed to redirect the product's orientation simultaneously with the conveying direction. Some existing turning conveyor lines use multiple synchronously rotating conical rollers. While this type of conveyor can simultaneously change the product's orientation and conveying direction, maintaining consistency between them, it is structurally complex, has many parts, is inconvenient to maintain, and is costly. Summary of the Invention

[0004] The purpose of this invention is to provide a differential turning conveyor to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.

[0005] The technical solution adopted to solve the above-mentioned technical problems is as follows:

[0006] A differential turning conveyor includes: a frame and a first conveying device and a second conveying device mounted on the frame;

[0007] The first conveying device and the second conveying device are each provided with two pairs of conveying components. Each conveying component is provided with a feeding end and a discharging end. Each conveying component includes a conveying part and a conveying drive component. The conveying drive component is provided with a conveying drive end that is connected to the conveying part and causes the conveying part to move from the feeding end to the discharging end.

[0008] The feeding direction of the conveying assembly is defined as the direction from the feed end to the discharge end. The feeding directions of the two conveying assemblies arranged in pairs are consistent, while the feeding directions of the first conveying device and the second conveying device are inconsistent. The two feed ends of the second conveying device are respectively connected to the two feed ends of the first conveying device.

[0009] The differential speed turning conveyor provided by this invention has at least the following beneficial effects: incoming materials are conveyed sequentially by the first and second conveying devices, changing the material's original conveying direction (which was aligned with the feeding direction of the first conveying device) to the feeding direction of the second conveying device. When the material is conveyed on the first and second conveying devices: the paired conveying components can be preset with different conveying speeds, and the material can rotate due to the different speeds of the conveying parts, thereby changing the material's orientation. The differential speed turning conveyor of this invention, through the first and second conveying devices that feed material in different directions, allows the material's conveying direction to change; simultaneously, the speed difference between the paired conveying components allows the material to rotate during conveying, thereby changing its orientation. Controlling the speed difference between the paired conveying components can change the material's rotation amplitude, allowing the material's orientation to be set at any angle to its conveying direction when exiting the differential speed turning conveyor.

[0010] As a further improvement to the above technical solution, the conveying assembly includes a conveyor belt, and the conveying drive component includes a conveying drive unit and two drive wheels. The two drive wheels are respectively located at the feed end and the discharge end, and the axes of both drive wheels are perpendicular to the feeding direction. Both drive wheels are connected to the frame, and the conveying drive unit is drivenly connected to one of the drive wheels. The conveyor belt is wound around the two drive wheels and is drivenly connected to them. The conveying section is located on the upper surface of the conveyor belt. Through this technical solution, the conveyor belt can be wound around the two drive wheels, allowing its surface to support and convey materials. The cyclically wound conveyor belt can move cyclically, achieving uninterrupted feeding. The drive unit can drive the drive wheels to rotate, thereby driving the conveyor belt to move cyclically and convey materials.

[0011] As a further improvement to the above technical solution, the conveying assembly further includes a belt support member, which is disposed between the two drive wheels and connected to the frame. The belt support member has a belt support portion extending along the feeding direction, located on the inner side of the conveyor belt. Through this technical solution, the belt support portion of the belt support member can support the inner surface of the conveyor belt, preventing the middle of the conveyor belt from easily sinking, causing material to bounce and affecting the conveying process.

[0012] As a further improvement to the above technical solution, the support belt is provided with a first connecting portion and a second connecting portion arranged along the feeding direction, both of which are adjustablely connected to the frame in the vertical direction. Through this technical solution, the height of both ends of the support belt can be adjusted as needed, facilitating docking between the two ends of the conveying assembly and making the material flow more smoothly when entering or exiting the conveying assembly.

[0013] As a further improvement to the above technical solution, the support belt portion has a groove structure, and the shape of the support belt portion is consistent with the inner shape of the conveyor belt. Through this technical solution, the groove structure of the support belt portion can limit and guide the inner side of the conveyor belt, allowing the inner side of the conveyor belt to move within the support belt portion, effectively preventing the conveyor belt from swaying during movement and causing abnormalities.

[0014] As a further improvement to the above technical solution, the conveying sections of each of the conveying components are all located on the same horizontal plane, with the width direction of the conveying component being perpendicular to the feeding direction and parallel to the horizontal direction. The conveying component is adjustablely connected to the frame along the width direction. Through this technical solution, the horizontally aligned conveying sections can smoothly convey materials, preventing them from easily tipping over. The conveying components can be adjusted in position along the width direction, allowing the spacing between paired conveying components to be set according to the size of the material.

[0015] As a further improvement to the above technical solution, the first conveying device and the second conveying device further include a omnidirectional ball conveying component. The omnidirectional ball conveying component is disposed between the paired conveying components and connected to the frame. The omnidirectional ball conveying component includes multiple omnidirectional ball units arranged along the feeding direction. Through this technical solution, the omnidirectional ball conveying component can support the material at the position between the two conveying components. The omnidirectional ball units roll in contact with the bottom of the material, without obstructing the conveying or rotation of the material.

[0016] As a further improvement to the above technical solution, both the first conveying device and the second conveying device are installed on the top of the frame. The bottom of the frame has multiple downward-extending columns, each with an adjustable support leg at its base. The distance between the adjustable support leg and the top of the frame is adjustable. Through this technical solution, the height of the frame can be adjusted as needed, and the heights of the first and second conveying devices can be adjusted according to the corresponding height of the connection points.

[0017] The present invention also provides a turning conveyor line, comprising: a first conveyor line, a second conveyor line, and the aforementioned differential turning conveyor device; the conveying direction of the first conveyor line is consistent with the feeding direction of the first conveyor device, and the downstream end of the first conveyor line is connected to the two feeding ends of the first conveyor device; the conveying direction of the second conveyor line is consistent with the feeding direction of the second conveyor device, and the upstream end of the second conveyor line is connected to the two discharging ends of the first conveyor device.

[0018] The turning conveyor line provided by the present invention has at least the following beneficial effects: the incoming material from the previous process can be fed into the differential turning conveyor along the first conveyor line, and the conveying direction and material orientation are changed in the differential turning conveyor, and then it is sent out along the second conveyor line to enter the next process.

[0019] As a further improvement to the above technical solution, the conveying speed of the second conveyor line is not lower than that of the first conveyor line, and the conveying speeds of both the first and second conveying devices are not lower than that of the first conveyor line. Through this technical solution, incoming materials are sequentially conveyed on the first conveyor line, the differential turning conveyor, and the second conveyor line. The conveying speeds of the first and second conveying devices, as well as the second conveyor line, are all not lower than those of the first conveyor line, which can prevent material accumulation. It is worth noting that the faster the conveying speed, the greater the positional distance between adjacent materials. For materials that are not circular on a projection plane perpendicular to the vertical direction, the required material spacing increases when the material rotates; for materials whose orientation changes, the material spacing also needs to be increased. The conveying speeds of the first conveyor, the second conveyor, and the second conveyor line can be set according to the material conveying requirements. Attached Figure Description

[0030] Reference Figures 1 to 4 The turning conveyor line of the present invention is provided in the following embodiment:

[0031] A turning conveyor line includes: a first conveyor line 500, a second conveyor line 600, and a differential turning conveyor device.

[0032] The differential turning conveyor includes: a frame 100, a first conveying device 200, and a second conveying device 300.

[0033] The first conveying device 200 and the second conveying device 300 are both mounted on the top of the frame 100. The bottom of the frame 100 has multiple downward-extending columns 110, each with an adjustable support leg 111 at its bottom end.

An adjusting bolt is also provided between the column 110 and the adjustable support leg 111. The adjusting bolt extends axially in the vertical direction and is rotatably connected to the adjustable support leg 111 and threadedly connected to the column 110. In some embodiments, the adjustable support leg 111 can be a foot cup with a vertically extending stud threadedly attached to the bottom end of the column 110.

[0034] The first conveying device 200 and the second conveying device 300 are each provided with two pairs of conveying components 400.

[0035] The conveying assembly 400 is provided with an inlet end and an outlet end. The conveying assembly 400 includes a conveying section 411 and a conveying drive component 420. The conveying drive component 420 is provided with a conveying drive end that is pulsatorically connected to the conveying section 411 and moves the conveying section 411 from the inlet end to the outlet end.

[0036] To facilitate the transport of flat products, in this embodiment, the transport assembly 400 adopts a structure of a pulley-driven conveyor belt 410. The transport assembly 400 includes a conveyor belt 410, and the transport drive component 420 includes a transport drive unit 421 and two drive wheels 422. The two drive wheels 422 are respectively located at the feed end and the discharge end. The axial directions of the two drive wheels 422 are perpendicular to the feeding direction. Both drive wheels 422 are connected to the frame 100. The transport drive unit 421 is drivenly connected to one of the drive wheels 422. The conveyor belt 410 is wound around the two drive wheels 422 and is drivenly connected to the two drive wheels 422. The transport section 411 is located on the upper surface of the conveyor belt 410.

[0037] To facilitate control of the conveying speed and accuracy, the conveying drive unit 421 in this embodiment adopts a servo motor. In other embodiments, the conveying drive unit 421 may be a stepper motor or a pneumatic motor or other rotary drive element.

[0038] The conveying assembly 400 also includes a support belt 430. The support belt 430 is disposed between the two drive wheels 422 and connected to the frame 100. The support belt 430 has a support portion extending along the feeding direction, and the support portion is disposed on the inner side of the conveyor belt 410.

[0039] In this embodiment, the conveyor belt 410 is a flat belt, and the support portion is a flat plane. In other embodiments, the conveyor belt 410 may be a V-belt or a round belt, etc. The support portion has a groove structure, and the shape of the support portion is consistent with the inner shape of the conveyor belt 410. Similarly, the outer periphery of the drive wheel 422 is also provided with a groove structure with a shape consistent with the inner side of the conveyor belt 410.

[0040] The support belt 430 is provided with a first connecting part and a second connecting part arranged along the feeding direction. Both the first connecting part and the second connecting part are adjustablely connected to the frame 100 in the vertical direction.

[0041] The feeding direction of the conveying assembly 400 is defined as the direction from the inlet end to the outlet end. The feeding directions of the two paired conveying assemblies 400 are the same, while the feeding directions of the first conveying device 200 and the second conveying device 300 are different. The two inlet ends of the second conveying device 300 are respectively connected to the two inlet ends of the first conveying device 200.

[0042] The conveying direction of the first conveyor line 500 is consistent with the feeding direction of the first conveying device 200, and the downstream end of the first conveyor line 500 is connected to the two feed ends of the first conveying device 200. The conveying direction of the second conveyor line 600 is consistent with the feeding direction of the second conveying device 300, and the upstream end of the second conveyor line 600 is connected to the two discharge ends of the first conveying device 200.

[0043] To prevent material accumulation due to slowed material conveying speed, which could cause material damage from impacts, the conveying speed of the second conveyor line 600 is not lower than that of the first conveyor line 500, and the conveying speeds of both the first conveyor device 200 and the second conveyor device 300 are not lower than that of the first conveyor line 500. It is worth noting that the conveying speed of the first conveyor device 200 refers to the conveying speed of the slower conveying component 400 within the first conveyor device 200; similarly, the conveying speed of the second conveyor device 300 refers to the conveying speed of the slower conveying component 400 within the second conveyor device 300.

[0044] When using the turning conveyor line of the present invention: incoming materials are sequentially conveyed on the first conveyor line 500, the differential turning conveyor, and the second conveyor line 600. When the material enters the inlet of the second conveyor 300 from the outlet end of the first conveyor 200, the conveying direction of the material changes from the feeding direction of the first conveyor 200 to the feeding direction of the second conveyor 300.

[0045] To balance the force and prevent material from falling, in this embodiment, the conveying sections 411 of each conveying assembly 400 are all located on the same horizontal plane. The width direction of the conveying assembly 400 is defined as perpendicular to the feeding direction and parallel to the horizontal direction, and the conveying assembly 400 is adjustablely connected to the frame 100 along the width direction. The conveying assembly 400 is provided with a drive shaft 423 extending along the width direction, and the drive wheel 422 is adjustablely coaxially mounted to the drive shaft 423 along the width direction. Similarly, the support belt 430 is adjustablely connected to the frame 100 along the width direction.

[0046] The first conveying unit has two conveying components 400, namely a first outer conveying component 400 and a first inner conveying component 400. The second conveying unit has two conveying components 400, namely a second outer conveying component 400 and a second inner conveying component 400. The feed end of the second outer conveying component 400 is connected to the discharge end of the first outer conveying component 400, and the feed end of the second inner conveying component 400 is connected to the discharge end of the first inner conveying component 400.

[0047] In this embodiment, the first conveying device 200 is positioned forward, and the second conveying device 300 is located beside the front end of the first conveying device 200, with its feeding direction facing left. The first inner conveying component 400 and the first outer conveying component 400 are respectively located on the left and right sides of the first conveying device 200, while the second outer conveying component 400 and the second inner conveying component 400 are respectively located on the front and rear sides of the second conveying device 300.

[0048] When incoming materials are conveyed on the differential speed turning conveyor, the speed difference between the two conveying components 400 causes the materials to rotate during the conveying process. In this embodiment, viewed from top to bottom: when the conveying speed of the first inner conveying component 400 is higher than that of the first outer conveying component 400, the material rotates clockwise during the conveying process of the first conveying device 200; conversely, the material rotates counterclockwise. When the conveying speed of the second inner conveying component 400 is higher than that of the second outer conveying component 400, the material rotates clockwise during the conveying process of the second conveying device 300; conversely, the material rotates counterclockwise.

[0049] In some embodiments, the first conveying device 200 and the second conveying device 300 further include a ball joint conveying component.
