Description

Technical Field

[0001] This invention relates to the technical field of feeding equipment, and in particular to a double-layer staggered box-changing device with a high-low alternating conveying mode. Prior Technology

[0002] In traditional processing, the method of transporting materials to the processing machine usually involves using a crane to lift a material bucket, hoist it to the processing machine, and then unload it for processing. Since the processing machine is usually a long distance from the feeding end, using a crane for lifting and transporting is not only time-consuming but also quite dangerous due to the height of the operation. Therefore, to solve the problems of the traditional feeding method, a feeding trolley is set up. Two tracks are erected between the feeding end and the processing end, and a material bucket is placed on each track. The material to be processed is poured into the material bucket from the feeding end, and then the feeding trolley moves the material bucket along the tracks to the processing machine, where the material is unloaded for processing. The empty bucket left after the material is poured into the processing machine is then moved back to the feeding end along the tracks for the next batch of feeding. However, in the traditional dual-track feeding method, the second batch of feeding cannot be carried out until the first batch of empty buckets returns, which is quite time-consuming and does not meet production efficiency. Summary of the Invention

[0003] The main objective of this invention is to provide a transfer machine that allows for the alternating transport of material boxes and empty boxes, so that material boxes can be transported without waiting for empty boxes to return to their positions, thereby shortening transport time and achieving the effects of saving time and improving production efficiency.

[0004] The double-layer staggered box-changing device disclosed in this invention consists of a main machine with a first conveyor platform at one end and a second conveyor platform at the other end. The first and second conveyor platforms are driven up and down by independent lifting mechanisms. The second conveyor platform has an upper conveyor platform and a lower conveyor platform that lift synchronously. The device mainly uses the upper and lower conveyor platforms of the second conveyor platform to provide material buckets and empty buckets, forming staggered conveying, shortening waiting time, and achieving time-saving and improved production efficiency.

[0005] To achieve the aforementioned objectives and effects, the double-layer box-changing equipment includes a main machine platform, a first transfer platform located at one end of the main machine platform, and a second transfer platform located at the other end of the main machine platform. The first transfer platform is driven to rise and fall by an independent lifting mechanism and has one or more transfer channels. A box-transfer mechanism is located at the bottom of each transfer channel. This box-transfer mechanism includes a roller assembly with several parallel rollers, each roller having a toothed disc at one end connected by a chain. A power unit provides power to drive the rollers to roll synchronously. Limiting wheel assemblies are located on both sides above the rollers, and a stop device is located at the end of the transfer channel. The second transfer platform includes a lifting mechanism and an upper and lower conveyor platform connected to the lifting mechanism. The upper conveyor platform has… There is one or more upper-level conveyor channels, each with a conveying mechanism at its bottom. The conveying mechanism includes a roller assembly with several parallel rollers, each with a toothed disc at one end connected by a chain. A power unit provides power to drive the rollers to roll. Limiting wheel assemblies are also provided on both sides above the rollers, and a stop device is located at the end of the conveyor channel. A lower-level conveyor platform has one or more lower-level conveyor channels, each with a conveying mechanism at its bottom. This conveying mechanism includes a roller assembly with several parallel rollers, each with a toothed disc at its head or tail end connected by a chain. A power unit provides power to drive the rollers to roll, used to convey material boxes or empty boxes. A stop device is located at the end of the roller assembly to prevent the material box from advancing.

[0006] The core technology of this invention is that the double-layer staggered box-changing device is located between the feeding platform at the inlet and the feeding platform at the outlet. The second conveyor platform, which is close to the feeding platform at the outlet, has an upper conveyor platform and a lower conveyor platform. The upper and lower conveyor platforms are driven by a lifting mechanism to achieve synchronous lifting. Through the upper and lower conveyor platforms of the second conveyor platform, the transport of the material buckets and empty buckets is staggered, allowing the material buckets and empty buckets to enter and exit from different directions, reducing waiting time, thereby achieving the purpose of saving time and improving production efficiency.

[0025] Please refer to Figure 1. The staggered box-changing device of the present invention includes a main machine platform 1, a first transfer platform 2 disposed at one end of the main machine platform 1, and a second transfer platform 3 disposed at the other end of the main machine platform 1. The first transfer platform 2 is connected and driven to move up and down by an independent lifting mechanism 20, and includes one or more transfer channels 21 (two are shown in the figure, but since the structure is the same, only one transfer channel is described). The bottom of the transfer channel 21 is provided with a box-transfer structure, which includes a roller assembly 22. The roller assembly 22 has several horizontally parallel rollers 220, and each roller 220 has a toothed disc 221 fixed at its tail or end, which is meshed with each other by a chain 222. The gear 221 is powered by a power unit (not disclosed) to drive the chain 222, which in turn drives each roller 220 to rotate synchronously. A stop device (not disclosed) is provided at the end of the roller assembly 22. The stop device has a stop bar 210. A limit wheel assembly 230 is vertically mounted on both sides of the roller assembly 22 by angle iron 23. The limit wheel assembly 230 has a frame plate 231. Several limit wheels 232 are arranged inside the frame plate 231, and the limit wheels 232 are aligned inward and their protruding ends are flush. A guide block 233 is provided at the feed end of the limit wheel 232 to guide the material box forward. The limit wheel 232 contacts the material box and positions it to prevent deviation.

[0026] The second conveying platform 3 is driven to move up and down by an independent second lifting mechanism 30. It includes a second lifting mechanism 30 and an upper conveying platform 31 and a lower conveying platform 34 connected to the second lifting mechanism 30 in an upper-lower configuration. The upper conveying platform 31 has one or more upper conveying channels 310 (two are shown in the illustration, but due to their identical structure, only one channel is described). The bottom of the upper conveying channel 310 is equipped with a conveying mechanism, which includes a roller assembly 311. The roller assembly 311 has several rollers 312, and toothed discs 31 are fixed at the tail or end of each roller 312. 3. The chain 314 meshes with each toothed disc 313, and the chain 314 is driven by a power unit (not disclosed) to drive each roller 312 to rotate synchronously. On both sides of the roller assembly 311, a limiting wheel assembly 330 is vertically mounted with angle iron 33. The limiting wheel assembly 330 includes a frame plate 331 and several limiting wheels 332 located inside the frame plate 331, with the limiting wheels 332 facing inward and the protruding ends of the limiting wheels 332 being flush. In addition, a guide block 333 is provided at the feeding end of the limiting wheel 332 to guide the material box forward, and the limiting wheel 332 contacts and positions it to prevent deviation. A stop device is fixed at the front end of the roller assembly 311 of the upper conveyor 31. The stop device includes a stop rod 334 and a pneumatic cylinder 335 connected to the stop rod 334. The stop rod 334 has a fixed fulcrum 336. The pneumatic cylinder 335 controls the stop rod 334 to protrude upward or lower, so as to block the empty box from moving forward or to release it.

[0027] The lower conveyor platform 34 has one or more lower transfer channels 340. A conveying mechanism is provided at the bottom of each lower transfer channel 340. This conveying mechanism includes a roller assembly 341 with several rollers 342. Gear discs 343 are fixed to the tail or end of each roller 342. A chain 344 meshes with each gear disc 343. Power is provided by a power unit (not disclosed) to drive each roller 342 to rotate synchronously. A stop device is also provided at the rear end of the roller assembly 341. It forms an opposite linkage with the stop device at the end of the roller group 22 of the first transfer table 2 (i.e., a rising and falling arrangement), and its structure is the same as the stop device of the upper conveyor table 31 (not shown in the figure). In addition, several stop columns 35 are provided on the main body 1 corresponding to the bottom of the lower conveyor table 34 of the second transfer table 3 to limit the descent height of the second transfer table 3. Through the restriction of the stop columns 35, the transfer channel 21 of the first transfer table 2 and the lower conveyor table 34 of the second transfer table 3 are aligned, which is conducive to transportation.

[0028] Regarding the feeding process of this invention, please refer to Figures 3 to 17. After the unprocessed part 5 to be fed is placed into the material box 4, it is hoisted into the transfer channel 21 of the first transfer table 2 by a crane (see Figure 3). The material box 4 is then placed on the rollers 220 of the roller assembly 22. Since the width of the material box 4 matches the width of the transfer channel 21, the material box 4 will be touched by the protruding end of the limiting wheel 232. The limiting wheel 232 of the limiting wheel assembly 230 restricts the material box 4 to prevent it from shifting when it is transferred by the rollers 220. After the material box 4 is properly placed on the rollers 220, it is located at the end of the transfer channel 21. The stop device 210 protrudes upward to prevent the material box 4 from moving further (as shown in Figures 3 and 4). Then, the power unit is activated to provide power to drive the chain 222 to rotate the roller 220 synchronously and lower the stop 210. This allows the material box 4 to move forward and be transferred from the transfer channel 21 of the first transfer platform 2 to the lower transfer platform 34 of the second transfer platform 3, which is flush with it. The material box 4 then enters the lower transfer channel 340 of the lower transfer platform 34. At this time, the stop device 337 rises to block and position the material box 4 in the lower transfer channel 340 of the second transfer platform 3 (as shown in Figures 5 and 6).

[0029] When the material box 4 is positioned in the lower transfer channel 340 of the second transfer platform 3, the second lifting mechanism 30 is activated to rise, driving the lower transfer channel 340 upward to the track feeding end (as shown in Figure 7). This moves the material box 4 onto the feeding platform 7 on the track 70, allowing the material box 4 to follow the feeding platform 7 along the track 70 to the processing end for unloading (as shown in Figure 8). After all the material parts 5 in the material box 4 have been emptied, the empty box 6 is returned to the track feeding end with the feeding platform (see Figure 9). The empty box 6 on the feeding platform 7 is then transferred to the upper transfer channel 310 of the second transfer platform 3 (as shown in Figure 10). Then, the second lifting mechanism 30 is activated. The second lifting mechanism 30 descends, causing the lower transfer channel 340 to descend as well. Positioned by the lower stop 35, it accurately aligns with the transfer channel 21 of the first transfer platform 2, aligning the rollers 342 of the lower transfer channel 340 with the rollers 220 of the first transfer platform 2's transfer channel 21. This allows it to receive the material box 4, which is hoisted into the transfer channel 21 of the first transfer platform 2. Driven by the rollers 220, it then enters the lower transfer channel 340 of the second transfer platform 3 and is stopped by the stop bar 337 (as shown in Figures 10 and 11). At this point, the upper transfer channel 310 of the second transfer platform 3 carries an empty box 6, while the lower transfer channel 340 of the second transfer platform 3 carries the material box 4. As shown in Figure 12), a signal is generated to activate the second lifting mechanism 30, causing the second transfer platform 3 to rise. This aligns the lower transfer channel 340 of the second transfer platform 3 with the feeding platform 7 at the end of the feeding track, thereby receiving the material box 4 onto the feeding platform 7. The material box 4 then moves along the track 70 to the processing end for unloading. Through the lifting and lowering of the second lifting mechanism 30, the empty box 6 and the material box 4 are transferred separately. The material box 4 first rises from the lower transfer channel 340 to the end of the feeding track and is pushed to the feeding platform 7, then slides along the track 70 to the processing end for unloading (as shown in Figures 13 and 14). The empty box 6 is then lowered by the second lifting mechanism 30 from the upper transfer channel 310 of the second transfer platform 3. The height is adjusted so that, while the first transfer platform 2 is descending, the transfer channel 21 of the first transfer platform 2 is simultaneously raised by the lifting mechanism 20 to the upper transfer channel 310 of the second transfer platform 3 (as shown in Figure 15), so that the transfer channel 21 and the upper transfer channel 310 are at the same height. Then, the roller 312 is driven to transfer the empty box 6 from the upper transfer channel 310 of the second transfer platform 3 to the transfer channel 21 of the first transfer platform 2 (as shown in Figure 16). Then, the lifting mechanism 20 drives the first transfer platform 2 to descend to the original height (as shown in Figure 17) and continues to lift the empty box 6 to the feeding end to continue loading. Through such a cyclical transfer, the empty box and the material box are transferred separately, reducing the waiting time and achieving time saving and improved production efficiency.
