Description

Technical Field

[0001] The present invention relates to a roller conveyor with an independent acceleration function, belonging to the technical field of conveyor lines. Background Art

[0002] Conveyor lines are mainly used to complete the transportation task of materials. In the areas surrounding warehouses, production workshops, and packaging workshops, there are conveyor chains composed of many belt conveyors, roller conveyors, etc.

[0003] Currently, in the prior art, the Chinese invention patent application number: 202010550820.3 discloses a modular sprocket roller track line conveying system. In this conveying system, the motor drives the output gear of the reducer to rotate, drives the sprocket connected to the output gear of the reducer to rotate, and drives all roller groups to rotate through the transmission connection between adjacent sprockets, completing the operation of the entire roller track line. In this conveying system, although it can convey the conveyed items, there is also the problem of slow acceleration. Specifically, most of the conveyor lines use trays to carry materials. When the tray reaches a certain station, it needs to carry materials. The conveyor line using only rollers has high energy consumption during rapid start and stop during the conveying process and is restricted by the friction between the roller and the tray. The acceleration and deceleration cannot achieve the desired effect, resulting in a slow acceleration of the tray when the conveyor line starts again and affecting the conveying speed. If the tray wants to obtain a large acceleration, the power of the conveyor line must be segmented, and the accumulation function of local rollers is cancelled. This method will cause the tray to rebound and displace when it stops, not only affecting the stopping accuracy of the tray, but also causing wear due to the sliding friction between the tray and the rollers, making the acceleration effect unstable and not convenient for actual use. Summary of the Invention

[0035] To solve the above-mentioned technical problems and to further understand the content of the present invention, the following further elaborates on this technical solution in conjunction with specific embodiments.

[0036] Embodiment 1: As Figures 1 to 10 shown, this embodiment provides a roller conveyor with an independent acceleration function, which includes an accumulation conveyor line 1, an acceleration drive assembly 2, a lifting assembly 3, and a control system installed on a frame; the frame includes four support legs 5 and two parallel crossbeams 6, and the four support legs 5 are grouped in pairs and are respectively located below both ends of the crossbeam 6.

[0037] The accumulation conveyor line 1 is used to transport pallets 4; specifically, the accumulation conveyor line 1 includes a drive motor 10, a motor connection plate 11, a pedestal bearing 12, a bearing mounting plate 13, a transmission shaft 14, a double sprocket 15, and an accumulation roller assembly 19 installed on the crossbeam 6; among them, the drive motor 10 is installed on the motor connection plate 11, the motor connection plate 11 is fixed on the crossbeam 6, the pedestal bearing 12 is fixedly connected to the bearing mounting plate 13, both ends of the transmission shaft 14 respectively penetrate through the pedestal bearing 12 and are then connected to the transmission sprocket 16, the accumulation roller assembly 19 and the transmission sprocket 16 are driven by a single chain 17, the drive motor 10 drives the double sprocket 15 to rotate, and a double chain 18 connects the double sprocket 15 and the transmission sprocket 16 for driving, and the accumulation roller assembly 19 transports the pallets 4.

[0038] The acceleration drive assembly 2 is used to assist in accelerating the pallet 4 to the transportation speed of the accumulation conveyor line 1; as a specific implementation manner of this embodiment, specifically, the acceleration drive assembly 2 includes a brushless motor 20, a motor mounting plate 21, a first drive wheel 22, a second drive wheel 23, and a double-row drive wheel 25 and a transmission double-row sprocket 26 installed in a protective cover 24; among them, the brushless motor 20 is installed on the motor mounting plate 21, the brushless motor 20 drives the double-row drive wheel 25 to rotate, the double-row drive wheel 25 is respectively connected to the transmission double-row sprocket 26 through a single-row chain 27, the first drive wheel 22 and the second drive wheel 23 are respectively in driving cooperation with the transmission double-row sprocket 26, and the first drive wheel 22 and the second drive wheel 23 are used to drive the pallet 4 to move.

[0039] The lifting assembly 3 is used to drive the acceleration drive assembly 2 to approach and move away from the tray 4, and the lifting assembly 3 is installed below the acceleration drive assembly 2. As a specific implementation manner of this embodiment, specifically, the lifting assembly 3 includes a mounting connection plate 30, a pressure adjusting member 31, a return spring 32, an optical axis 33, a linear bearing 34, a connection bracket 35, a cylinder 36, a buffer pad 37, an adjusting block 38, a connection angle member 39, and a floating pull rod 40. One end of the connection angle member 39 is installed below the mounting connection plate 30, and the other end of the connection angle member 39 is installed on the motor mounting plate 21. The cylinder 36 is fixed on the fixed plate 41, and the buffer pad 37 and the adjusting block 38 are sequentially arranged below the cylinder 36. Both ends of the floating pull rod 40 are connected to the mounting connection plate 30 and the cylinder 36. The pressure adjusting member 31 is threadedly connected to the mounting connection plate 30, and both ends of the return spring 32 are respectively fixed on the pressure adjusting member 31 and the fixed plate 41. By screwing in or out the pressure adjusting member 31, the elastic force of the return spring 32 is adjusted. Specifically, when the friction between the first driving wheel 22, the second driving wheel 23 and the tray 4 is insufficient, in order to prevent the first driving wheel 22 and the second driving wheel 23 from slipping, the compression amount of the return spring 32 is adjusted to meet the operation requirements. The connection bracket 35 is located on the side of the fixed plate 41, the linear bearing 34 is installed on the fixed plate 41, one end of the optical axis 33 is fixed on the mounting connection plate 30, and the other end of the optical axis 33 passes through the linear bearing 34. The optical axis 33 plays a guiding role. The protective cover 24 is installed on the mounting connection plate 30, and the connection bracket 35 is fixed on the cross beam 6.

[0040] The control system is used to control the operation of the accumulation conveyor line 1, the acceleration drive assembly 2, and the lifting assembly 3. Specifically, the control system includes a PLC controller, a solenoid valve 7, and a detection sensor 8. The PLC controller is electrically connected to the drive motor 10, the brushless motor 20, the solenoid valve 7, and the detection sensor 8. The detection sensor 8 is installed on the cross beam 6 on the side where the acceleration drive assembly 2 is located. The solenoid valve 7 is connected and fixed to the connecting member 9, and then the connecting member 9 is fixed on the cross beam 6. The detection sensor 8 is used to detect whether the tray 4 is above the acceleration drive assembly 2. The detection sensor 8 feeds back the signal to the PLC controller, and the PLC controller controls the solenoid valve 7 to drive the cylinder 36 to operate. The solenoid valve 7 is installed on the cross beam 6 through the connecting member 9. In this embodiment, the detection sensor 8 adopts an optoelectronic switch.

[0041] Embodiment 2: As Figures 1 to 13 shown, on the basis of Embodiment 1, the first driving wheel 22 and the second driving wheel 23 drive the tray 4 to move. Due to the friction between the two, after a long time, there will be wear and powder will be generated. In order to collect the powder, two dust collection boxes 42 are provided on the side wall of the mounting connection plate 30.

[0042] As a specific implementation manner of this embodiment, the accumulation roller assembly 19 in this embodiment includes an adjustment pin 191, a pressure button 192, an accumulation spring 193, a pressing pad 194, a first friction plate 195, a driving sprocket, a first bearing 197, a second friction plate 198, a mounting housing, a second bearing 199, a transmission pin 1910, and a roller 1911. Among them, the adjustment pin 191 and the roller 1911 are respectively located at both ends of the transmission pin 1910. Specifically, the adjustment pin 191 penetrates along the radial direction of the transmission pin 1910, and the roller 1911 is sleeved on the outer periphery of the transmission pin 1910. Along the direction from the adjustment pin 191 to the roller 1911, a pressure button 192, an accumulation spring 193, a pressing pad 194, a first friction plate 195, an accumulation sprocket 196, a second friction plate 198, and a second bearing 199 are sequentially sleeved on the outer periphery of the transmission pin 1910. A first bearing 197 is sleeved between the accumulation sprocket 196 and the transmission pin 1910, and the second bearing 199 is located inside the housing of the cross beam 6. One end face of the pressure button 192 is a flat surface, and a plurality of continuous accommodation grooves 1912 are evenly distributed on the other end face of the pressure button 192, and the accommodation grooves 1912 are used for placing the adjustment pin 191. Since the materials on the tray 4 are heavy, a relatively large frictional force is required to drive the loading tray 4 to move. In order to ensure a relatively large frictional force to drive the tray 4 to move, the adjustment pin 191 is designed to compress the accumulation spring 193. Specifically, first, press the pressure button 192 in the direction where the accumulation spring 193 is located, so that the adjustment pin 191 is separated from the accommodation groove 1912, rotate the adjustment pin 191, and after releasing the pressure button 192, the adjustment pin 191 is stuck at the position of other accommodation grooves 1912, that is, by changing the position of the adjustment pin 191 in different accommodation grooves 1912, the frictional forces between the accumulation spring 193, the first friction plate 195, the accumulation sprocket 196, and the second friction plate 198 are increased or decreased.

[0043] In practical applications, as Figures 1 to 13 shown, taking Embodiment 2 as an example, in the initial state, the tray 4 is loaded with materials. The PLC controller controls the driving motor 10 to operate, the driving motor 10 drives the double sprocket 15 to rotate, and then the transmission sprocket 16 is transmitted with the accumulation sprocket 196 through the single chain 17, so as to realize that the roller 1911 drives the tray 4 to move in the direction of the acceleration driving assembly 2. At this time, the detection sensor 8 does not sense the tray 4, and the solenoid valve 7 controls the operation of the cylinder 36. Specifically, the cylinder 36 drives the floating pull rod 40 to move downward, and the return spring 32 is compressed, so that the height of the acceleration driving assembly 2 is lower than the conveying height of the roller 1911 of the accumulation conveyor line 1.

[0044] When the tray 4 is conveyed in place by driving the accumulation roller assembly 19 through the driving motor 10, that is, when the tray 4 is located above the acceleration driving assembly 2, the detection sensor 8 detects the position of the tray 4, the driving motor 10 stops rotating, and the tray 4 stops at this station. When the detection sensor 8 detects that the stop time of the tray 4 exceeds 1.5 s, the signal is transmitted back to the PLC controller, and the PLC controller controls the solenoid valve 7 to drive the cylinder 36 to eject. The floating pull rod 40 moves upward, so that the pressure of the return spring 32 is released. The return spring 32 resets and drives the first driving wheel 22 and the second driving wheel 23 to move upward until the first driving wheel 22 and the second driving wheel 23 contact the tray 4. When contacting, there is a certain pressing force between the first driving wheel 22, the second driving wheel 23 and the conveying tray 4, ensuring that there is a certain frictional force between the first driving wheel 22, the second driving wheel 23 and the tray 4 when starting again.

[0045] Subsequently, the brushless motor 20 and the driving motor 10 are started simultaneously. The response speed of the brushless motor 20 is higher than that of the driving motor 10. The brushless motor 20 can quickly accelerate the tray 4. At this time, the roller 1911 is in a slipping state, enabling the tray 4 to quickly reach the conveying speed of the accumulation conveying line 1. After the brushless motor 20 operates for 1.5 s, the solenoid valve 7 controls the cylinder 36 to descend. The cylinder 36 pulls the floating pull rod 40, so that the return spring 32 is compressed, thereby realizing the separation of the first driving wheel 22, the second driving wheel 23 and the tray 4. The tray 4 moves under the conveying of the accumulation conveying line 1. When the detection sensor 8 cannot detect the position of the tray 4, the PLC controller controls the brushless motor 20 to stop operating; this cycle repeats until the next tray 4 enters the inlet end of the accumulation conveying line 1. Through the coordinated cooperation among the accumulation conveying line 1, the acceleration driving assembly 2, the lifting assembly 3 and the control system, the tray 4 can obtain a large acceleration and does not affect the stop accuracy of the tray 4, solving the problem that the loading tray 4 starts slowly again and greatly improving the conveying efficiency.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
