Description

Technical Field

[0001] This application relates to the technical field of material transfer, and in particular to a reverse flow device. Background Technology

[0002] Typically, after the products produced on the production line are placed in the storage bins, the storage bins need to be moved.

[0003] In related technologies, material bins are mostly handled manually. Once a certain number of bins are stacked on the production line, users manually move them. However, this method is labor-intensive, time-consuming, and inefficient. Furthermore, the weight of bins containing products is usually considerable, posing a safety hazard as they can easily injure users during handling. Summary of the Invention

[0004] Therefore, it is necessary to provide a reversing flow device to address the aforementioned technical problems, so as to improve the transfer efficiency of the material box and enhance the safety during the transfer process.

[0005] A reversing and reflux device includes: a material rack; a transport assembly including a feeding unit fixedly connected to the material rack and a reflux unit rotatably connected to the material rack, the feeding unit being used to transport a material box to the reflux unit, the reflux unit having an input position that can be connected to the feeding unit and an output position that is away from the feeding unit; an operating member rotatably connected to the material rack; and a transmission assembly including a first transmission unit and a second transmission unit, the first transmission unit drivingly connecting the operating member and the reflux unit, and the second transmission unit drivingly connecting to the reflux unit; wherein, when the operating member rotates relative to the material rack, the operating member can drive the reflux unit to rotate from the input position to the output position via the first transmission unit, and at the same time, the reflux unit can drive the second transmission unit to move, so that the second transmission unit can block the movement of the material box relative to the feeding unit.

[0006] In one embodiment, the reversing reflux device further includes a reset member, the two ends of which are connected to the feed rack and the reflux unit, respectively, for restoring the reflux unit from the output position to the input position.

[0007] In one embodiment, the feeding unit includes a feeding element and a feeding roller. The feeding element is fixedly connected to the material rack, and the feeding roller is rotatably connected to the feeding element and spaced apart within the feeding element. At the input position, the feeding element is connected to the return unit.

[0008] In one embodiment, the recirculation unit includes a recirculation component, a recirculation roller, and a transmission component. The recirculation component is connected to a first transmission unit and rotatably connected to a material rack. The transmission component is connected to the recirculation component and a second transmission unit and can rotate with the recirculation component and drive the second transmission unit to move. The recirculation roller is rotatably connected to the recirculation component and is spaced apart within the recirculation component.

[0009] In one embodiment, the second transmission unit includes a first transmission rod, a second transmission rod, a connecting rod, and a stop rod. One end of the first transmission rod is connected to the return unit, and the other end is rotatably connected to one end of the connecting rod. The other end of the connecting rod is connected to the second transmission rod. The second transmission rod is rotatably connected to the material rack. The stop rod is connected to the second transmission rod and can move relative to the feeding unit.

[0010] In one embodiment, when the operating member rotates, the recirculation unit is configured to rotate about a first axis relative to the material rack, and the second drive rod is configured to rotate about a second axis relative to the material rack, the first axis being perpendicular to the second axis.

[0011] In one embodiment, the transport component further includes a discharge unit fixedly connected to the material rack for discharging the material box to a preset position. At the discharge position, a return unit is connected to the discharge unit so that the material box on the return unit can be transferred to the discharge unit.

[0012] In one embodiment, the discharge unit includes a discharge component and a discharge roller. The discharge component is fixedly connected to the material rack, and the discharge roller is rotatably connected to the discharge component and spaced apart within the discharge component. At the output position, the discharge component is connected to the return unit.

[0013] In one embodiment, the first transmission unit includes a first driven rod, a second driven rod, and a third driven rod. The first driven rod is connected to the operating member, the second driven rod is perpendicular to the first and third driven rods and its two ends are respectively connected to the first and third driven rods, and the third driven rod is connected to the return unit.

[0014] In one embodiment, the rack includes a base frame and a support frame. The base frame is parallel to the placement plane, the support frame is vertically connected to the base frame and disposed at opposite ends of the base frame, and the operating element is rotatably connected to the base frame.

[0015] The aforementioned reversing and reflux device, through the arrangement of the feeding unit, enables the material boxes on the production line to be transferred from the feeding unit to the reflux unit. Then, by driving the operating component, which rotates relative to the material rack, and via the first transmission unit, drives the reflux unit to rotate, the material boxes on the reflux unit are transferred to the output position. This material box transfer process only requires driving the operating component to rotate, making it convenient to operate. Furthermore, the rotation of the reflux unit drives the second transmission unit to move, preventing the material boxes on the feeding unit from moving to the reflux platform. This achieves orderly transfer of multiple material boxes on the production line, thereby improving the transfer efficiency and safety of the material boxes during the transfer process.

[0027] See Figure 1 , Figure 1 A schematic diagram of a reversing flow device according to an embodiment of this application is shown. The reversing flow device 100 provided in one embodiment of this application includes a material rack 10, a transport assembly 20, an operating component 30, and a transmission assembly 40.

[0028] The rack 10 is the main body of the reversing return device 100, providing installation space and support for the transport component 20, the operating component 30, and the transmission component 40. By abutting the rack 10 against the production line, the material boxes on the production line can be transferred to the transport component 20, thereby conveying the material boxes through the reversing return device 100.

[0029] The transport component 20 provides a transfer route for the product-containing bins, enabling them to be moved from the production line to a preset location without manual handling. Combined with... Figure 2The transport component 20 includes a feeding unit 21 and a return unit 22. The feeding unit 21 is fixedly connected to the material rack 10 and forms a feeding channel for conveying the material box to be rotated to the return unit 22.

[0030] The return unit 22 is rotatably connected to the material rack 10. The return unit 22 has an input position and an output position. In the input position, the return unit 22 is connected to the feeding unit 21, allowing the hopper to be rotated on the feeding unit 21 to move onto the return unit 22. In the output position, the return unit 22 rotates away from the feeding unit 21, allowing the hopper on the return unit 22 to move to a preset position. The preset position can be the next workstation, a storage position, or the operator's position, etc.

[0031] The operating component 30 is rotatably connected to the material rack 10. The operating component 30 is designed for user operation, allowing the material box to be transferred on the transport assembly 20 by the user's drive of the operating component 30. In this embodiment, the operating component 30 is a foot pedal. By applying force to the foot pedal, the operator causes the foot pedal to rotate, thereby driving the return unit 22 to rotate from the input position to the output position, completing the material box transfer process.

[0032] The operating component 30 has an initial state and an operating state. In the initial state, the return unit 22 is in the input position. In the operating state, the operating component 30 rotates relative to the material rack 10 by a preset angle, causing the return unit 22 to rotate from the input position to the output position.

[0033] The transmission assembly 40 transmits the driving force of the operating element 30 to the return unit 22, thereby enabling the rotation of the return unit 22 and facilitating control of the material bin transfer process. (See also...) Figures 1 to 4 The transmission assembly 40 includes a first transmission unit 41 and a second transmission unit 42. The first transmission unit 41 is connected to the operating member 30 and the return unit 22, and the second transmission unit 42 is connected to the return unit 22.

[0034] When the operating component 30 rotates relative to the material rack 10, the operating component 30 can drive the return unit 22 to rotate from the input position to the output position via the first transmission unit 41. That is, the first transmission unit 41 is used to convert the driving force of the operating component 30 into the rotation of the return unit 22. At the same time, the return unit 22 can drive the second transmission unit 42 to move. That is, the second transmission unit 42 is used to convert the rotation of the return unit 22 into its own movement, so that the second transmission unit 42 can block the material box from moving relative to the feeding unit 21, that is, to realize that only one material box is transferred each time the operating component 30 is driven.

[0035] By setting up the feeding unit 21, the material boxes on the production line can be transferred from the feeding unit 21 to the return unit 22. Then, by driving the operating component 30, the operating component 30 rotates relative to the material rack 10, and the operating component 30 can drive the return unit 22 to rotate via the first transmission unit 41, so that the material boxes on the return unit 22 can be transferred to the output position. This material box transfer process only requires driving the operating component 30 to rotate to complete the material box transfer, which is convenient to operate. Furthermore, when the return unit 22 rotates, it can drive the second transmission unit 42 to move, so that the second transmission unit 42 can prevent the material boxes on the feeding unit 21 from moving to the return platform, realizing the orderly transfer of multiple material boxes on the production line, thereby improving the material box transfer efficiency and enhancing the safety of the material boxes during the transfer process.

[0036] Specifically, in this embodiment, see [reference] Figure 1 The material rack 10 includes a base frame 11 and a support frame 12. The base frame 11 is parallel to the placement plane, and the support frame 12 is vertically connected to the base frame 11 and disposed at opposite ends of the base frame 11 to facilitate the installation and connection of the transport assembly 20. The operating member 30 is rotatably connected to the base frame 11.

[0037] Specifically, in this embodiment, the base frame 11 includes two first base rods 11 and two second base rods 12 arranged opposite to each other, with the ends of the first base rods 11 and the ends of the second base rods 12 connected sequentially. The support frame 12 includes at least a first support rod 121, a second support rod 122, a third support rod 123, and a fourth support rod 124 arranged at intervals, with two sets of support frames 12 vertically connected to the two second base rods 12. In this application, the first support rod 121 and the fourth support rod 124 are positioned at the connection between the first base rods 11 and the second base rods 12. The second support rod 122 and the third support rod 123 are positioned between the first support rod 121 and the fourth support rod 124.

[0038] The base frame 11 and support frame 12 provide support for the transport component 20, the operating component 30 and the material box, so that the reversing return device 100 can remain stable, and thus the material box can remain stable during the transfer process, thereby ensuring that the material box can be stably and reliably transferred from the production line to the preset position.

[0039] Furthermore, the material rack 10 also includes a plurality of obliquely arranged reinforcing rods 13, one end of which is connected to the base frame 11 and the other end to the support frame 12. Specifically, the reinforcing rods 13 are arranged at the connection between the base frame 11 and the support frame 12, thereby providing reinforcement to the connection between the first support rod 121 and the second support rod 122 and enhancing the overall stability of the material rack 10.

[0040] In some embodiments, the rack 10 further includes a first connecting rod 14, the two ends of which are respectively connected to two first support rods 121, and the first connecting rod 14 is parallel to the base frame 11. Specifically, the first connecting rod 14 is further away from the placement plane than the base frame 11. The configuration of the first connecting rod 14 provides fixation to the other end of the first support rod 121, further increasing the stability of the rack 10.

[0041] Furthermore, the first connecting rod 14 is detachably connected to the first support rod 121. This detachable connection facilitates the disassembly and installation of the first connecting rod 14, improving ease of use and facilitating the overall storage of the material rack 10. Specifically, both the first support rod 121 and the first connecting rod 14 are provided with threaded holes, and bolts are threaded into these holes to achieve a detachable connection between the first connecting rod 14 and the first support rod 121.

[0042] In some embodiments, see Figure 5 The reflux unit 22 includes a reflux component 221, a reflux roller 222, and a transmission component 223. The reflux component 221 is fixedly connected to the first transmission unit 41 and rotatably connected to the material rack 10. The reflux roller 222 is rotatably connected to the reflux component 221 and is spaced apart within the reflux component 221. The transmission component 223 is connected to the reflux component 221 and the second transmission unit 42 and can rotate with the reflux component 221 and drive the second transmission unit 42 to move.

[0043] The return component 221 provides a platform for the material box, facilitating its rotation and thus enabling its transfer. The return roller 222 creates a rolling connection between the return unit 22 and the material box, facilitating the input and output of the material box to and from the return component 221. The transmission component 223 enables the return unit 22 to drive the second transmission unit 42 during rotation, providing a stable driving force for the second transmission unit 42.

[0044] Further, see Figure 5 The material rack 10 also includes a mounting frame 15 and a transmission frame 16. The mounting frame 15 is used for mounting the return component 221 and connecting the first transmission unit 41. The mounting frame 15 includes a first mounting rod 151, a second mounting rod 152, a third mounting rod 153, and a fourth mounting rod 154. Both ends of the first mounting rod 151 are connected to the second support rod 122. One end of the return component 221 is rotatably connected to the first mounting rod 151, and the other end is connected to the second mounting rod 152. The third mounting rod 153 is connected to the first transmission unit 41, and one end of the third mounting rod 153 is rotatably connected to the first mounting rod 151, while the other end is fixedly connected to the fourth mounting rod 154.

[0045] The transmission frame 16 is positioned on the side of the return member 221 away from the third mounting rod 153, with one end connected to the second mounting rod 152 and the other end rotatably connected to the first mounting rod 151. The transmission member 223 is fixedly connected to the transmission frame 16. The arrangement of the transmission frame 16 helps to stably transmit the driving force during the rotation of the return unit 22 to the transmission member 223, and then stably to the second transmission unit 42.

[0046] Specifically in this embodiment, combined with Figure 1 and Figure 3 The material rack 10 also includes a connecting frame 17, which includes a second connecting rod 171, a third connecting rod 172, and a fourth connecting rod 173. The two ends of the second connecting rod 171 are respectively connected to the fourth support rod 124, and the two ends of the third connecting rod 172 are respectively connected to the third support rod 123. The fourth connecting rod 173 is perpendicular to the third support rod 123 and the fourth support rod 124, and its two ends are respectively connected to the second connecting rod 171 and the third connecting rod 172.

[0047] The connecting bracket 17 provides an installation position for the feeding unit 21, allowing the feeding unit 21 to be installed onto the material rack 10. Furthermore, the fourth connecting rod 173 provides a further connection between the second connecting rod 171 and the third connecting rod 172, which helps improve the stability of the feeding unit 21, thereby enhancing the overall stability of the material rack 10.

[0048] Further, see Figure 2 and Figure 3 The feeding unit 21 includes a feeding component 211 and a feeding roller 212. The two ends of the feeding component 211 are fixedly connected to the second connecting rod 171 and the third connecting rod 172 of the material rack 10, respectively. The feeding roller 212 is rotatably connected to the feeding component 211 and is spaced apart within the feeding component 211. In the input position, the two ends of the feeding component 211 are connected to the production line and the return component 221, respectively, allowing the material bins of the production line to be input from the feeding component 211 to the return component 221.

[0049] The feed unit 211 is configured to define the direction in which the hopper enters the reversing return device 100 and provides an input placement platform for the hopper. The feed roller 212 is configured to enable a rolling connection between the feed unit 21 and the hopper, so as to facilitate the transport of the hopper to the return unit 22.

[0050] In some embodiments, see Figure 2The transport component 20 also includes a discharge unit 23, which is fixedly connected to the material rack 10. The discharge unit 23 is used to output the material box to be rotated on the return unit 22 to a preset position. At the output position, the return unit 22 is connected to the discharge unit 23, allowing the material box on the return unit 22 to be transferred to the discharge unit 23. The discharge unit 23 improves the output path for the material box, enabling it to be accurately output to the preset position.

[0051] Accordingly, see Figure 2 The connecting frame 17 also includes a fifth connecting rod 174 and a sixth connecting rod 175. The fifth connecting rod 174 is connected to the third support rod 123, and the sixth connecting rod 175 is connected to the fourth support rod 124. The configuration of the fifth connecting rod 174 and the sixth connecting rod 175 provides installation space for the discharge unit 23, so that the discharge unit 23 can be installed on the material rack 10.

[0052] Furthermore, the discharge unit 23 includes a discharge component 231 and a discharge roller 232. The two ends of the discharge component 231 are fixedly connected to the fifth connecting rod 174 and the sixth connecting rod 175 of the material rack 10, respectively. The discharge roller 232 is rotatably connected to the discharge component 231 and spaced apart within it. In the output position, the discharge component 231 is connected to the return unit 22. The discharge component 231 defines the discharge direction, allowing the material box to be transferred to a preset position by the return component 221. The discharge roller 232 enables a rolling connection between the discharge unit 23 and the material box, facilitating the transfer of the material box.

[0053] Preferably, the feeding unit 21, the return unit 22, and the discharging unit 23 are sequentially arranged on the material rack 10 in the direction facing the placement plane. That is, the second connecting rod 171, the third connecting rod 172, the first connecting rod 14, the fifth connecting rod 174, and the sixth connecting rod 175 are sequentially arranged in the direction facing the placement plane. This allows the material box to be transferred from the feeding unit 21 to the return unit 22 under its own gravity, then transferred from the return unit 22 to the discharging unit 23, and finally transferred from the discharging unit 23 to a preset position. This improves the convenience of material box transfer, helps reduce the driving force of the operator on the operating component 30, thereby reducing the operator's operating difficulty and improving the efficiency of transfer.

[0054] In feasible embodiments, see Figure 1The feeding unit 21, the return unit 22, and the discharge unit 23 are all configured in pairs, that is, the transport component 20 is configured in two pairs. The discharge ends of the two feeding units 21 can respectively abut against the feeding ends of the two return units 22, and the feeding ends of the two return units 22 can also respectively abut against the feeding ends of the two discharge units 23. Thus, during the transport of the box, both ends of the box are supported and transported by the two feeding units 21, the two return units 22, and the two discharge units 23, respectively. This arrangement helps to improve the stability of the box during the transport process.

[0055] Furthermore, two feeding units 21, two return units 22, and two discharging units 23 are spaced apart on the material rack 10. By adjusting the distance between the two transport components 20, the reversing return device 100 can be adapted to material boxes of different sizes, thereby improving the versatility of the reversing return device 100.

[0056] Preferably, the material rack 10 is provided with multiple transport components 20, operating components 30 and transmission components 40, so as to make full use of the space of the material rack 10, so that different material boxes can be transported simultaneously by different transport components 20 under the drive of different operating components 30, thereby improving the actual transport efficiency of the reversing flow device 100.

[0057] In some embodiments, see Figure 1 and Figure 2 The reversing reflux device 100 also includes a reset component. The two ends of the reset component are connected to the material rack 10 and the reflux unit 22, respectively, and are used to restore the reflux unit 22 from the output position to the input position. Simultaneously, the reflux unit 22 drives the operating component 30 from the operating state to the initial state via the first transmission unit 41. The reset component enables automatic reset of the reflux platform, which facilitates continuous transport of the material box and improves the material box transfer efficiency.

[0058] Specifically in this embodiment, combined with Figure 5 The reset component includes a first reset component 51 and a second reset component 52. The two ends of the first reset component 51 are respectively connected to the return component 221 and the first support frame 12, and the two ends of the second reset component 52 are respectively connected to the transmission component 223 and the third support frame 12.

[0059] Optionally, both the first reset member 51 and the second reset member 52 are springs. When the operating member 30 rotates, it drives the return platform to rotate. The rotation of the return platform causes the first reset member 51 and the second reset member 52 to be stretched, thereby generating elastic potential energy. After the operation on the operating member 30 is released, the first reset member 51 and the second reset member 52 will apply a pulling force to the return unit 22 in order to restore its original shape, so that the return unit 22 can return from the output position to the input position, and the operating member 30 rotates in the opposite direction relative to the material rack 10, returning from the operating state to the initial state, thereby continuing the transportation of the next material box. With the reset of the return unit 22, the second transmission unit 42 is also reset.

[0060] In some embodiments, see Figure 3 and Figure 5 The first transmission unit 41 includes a first driven rod 411, a second driven rod 412, and a third driven rod 413. The first driven rod 411 is fixedly connected to the operating member 30. One end of the second driven rod 412 is fixedly connected to the first driven rod 411, and the other end is fixedly connected to the third driven rod 413. The third driven rod 413 is fixedly connected to the return unit 22, so that as the operating member 30 rotates, the return unit 22 can rotate accordingly to realize the transfer of the material box.

[0061] Feasibly, the third driven rod 413 is connected to two spaced third mounting rods 153, so that the two spaced return units 22 can be rotated by an operating element 30, making the transfer of the material boxes placed on the two return units 22 at both ends more stable.

[0062] In some embodiments, see Figures 1 to 4 The second transmission unit 42 includes a first transmission rod 421, a second transmission rod 422, a connecting rod 423, and a stop rod 424. One end of the first transmission rod 421 is connected to the transmission component 223 of the return unit 22, and the other end is rotatably connected to one end of the connecting rod 423. The other end of the connecting rod 423 is connected to the second transmission rod 422. The second transmission rod 422 is rotatably connected to the rotating rod 177 of the material rack 10. The stop rod 424 is connected to the second transmission rod 422 and can move relative to the feeding unit 21, thereby preventing the material box from moving relative to the feeding unit 21.

[0063] Practically, the stop bar 424 abuts against the hopper, so that as the stop bar 424 moves upward, the hopper is lifted, applying a pushing force to the hopper, thereby stopping the hopper on the feeding unit 21 and preventing movement of the hopper relative to the feeding unit 21. In other embodiments, the stop bar 424 can move upward into the movement path of the hopper, thereby stopping the movement of the hopper.

[0064] When the return platform rotates, the first transmission rod 421 is subjected to pressure from the transmission component 223 of the return platform. The transmission component 223 moves downward, causing one end of the first transmission rod 421 to move downward with the transmission component 223. Since the other end of the first transmission rod 421 is rotatably connected to the connecting rod 423, the two ends of the first transmission rod 421 will be subjected to uneven force, causing the other end of the first transmission rod 421 to move upward, thereby driving one end of the connecting rod 423 to move upward and the other end to move downward. Since the second transmission rod 422 is rotatably connected to the material rack 10, the second transmission rod 422 rotates downward relative to the material rack 10, causing the stop rod 424 to move upward, thereby preventing the material box from moving relative to the feeding unit 21.

[0065] Furthermore, one end of the first transmission rod 421 is provided with a receiving groove 4211, and one end of the connecting rod 423 is provided with a rotating ball 4231. The rotating ball 4231 can be installed in the receiving groove 4211, thereby realizing the rotational connection between the first transmission rod 421 and the connecting rod 423.

[0066] In some embodiments, when the operating member 30 rotates, the reflux unit 22 is configured to rotate relative to the material rack 10 about a first axis, the extension direction of the first axis being parallel to the first base rod 111, and the second transmission rod 422 is configured to rotate relative to the material rack 10 about a second axis, the first axis being perpendicular to the second axis, and the extension direction of the second axis being parallel to the second base rod 112. This enables the second transmission rod 422 to cause the stop rod 424 to rotate upward while the reflux unit 22 rotates downward, thereby enabling the stop rod 424 to prevent the material box from moving relative to the feeding unit 21 while the reflux unit 22 rotates from the input position to the output position.

[0067] When using the reversing return device 100, it is first placed at the corresponding workstation on the production line, allowing the material box to move from the feeding end of the feeding unit 21 to the return unit 22. After the material box is placed on the return unit 22, the operating component 30 is stepped on, causing the operating component 30 to rotate downwards, which in turn drives the first transmission unit 41 to move downwards. This causes one end of the return unit 22 to move downwards synchronously, while the other end of the return unit 22 rotates relative to the material rack 10. As the return unit 22 rotates, the material box can move from the return unit 22 to the discharge unit 23. At the same time, the transmission component 223 of the return unit 22 drives the second transmission rod 422 to rotate downwards relative to the material rack 10, causing the stop rod 424 to move upwards to block the movement of the material box on the feeding unit, thus completing the material box transfer process. When the pedaling operation 30 stops, the return unit 22, under the action of the first reset member 51 and the second reset member 52, returns from the output position to the input position, causing the operating member 30 to rotate upward relative to the material rack 10, returning from the operating state to the initial state. Simultaneously, as the return unit 22 resets, the second transmission rod 422 also resets, causing the stop rod 424 to move away from the material box on the feeding unit, allowing the material box on the feeding unit to move onto the return unit 22 for the transfer of the next material box. This process is simple and convenient, requires no manual handling, saves manpower and time, improves the material box transfer efficiency, and ensures a safe and reliable transfer process.
