Description

Technical Field

[0001] This invention belongs to the technical field of cable tray palletizing machines, specifically a cable tray palletizing machine. Background Technology

[0002] As a crucial infrastructure for electrical wiring in modern buildings, the production efficiency and quality of cable trays directly impact project progress. The cable tray stacking device is an intelligent supporting equipment specifically designed for the end of the cable tray production line. It is primarily used for the automated collection and stacking of stamped and bent cable tray products, solving problems such as low efficiency, susceptibility to damage, and unstable stacking inherent in traditional manual stacking. This not only reduces labor intensity and costs but also minimizes safety hazards during handling.

[0003] The existing cable tray stacking device consists of a feeding mechanism, a translation mechanism, a stacking assembly, and a stacking station. The feeding mechanism is used to transport the finished cable trays. The stacking assembly clamps the cable trays, and the translation mechanism moves the stacking assembly with the clamped cable trays to the stacking station. The cable trays are then stacked on the stacking station. Through multiple cycles of operation, multiple sets of cable trays are stacked on the stacking station to achieve the stacking of cable trays.

[0004] In the process of stacking cable trays, the above-mentioned cable tray stacking device has only one set of stacking stations. When the number of cable trays stacked at each station reaches a certain number, the stacking station needs to be moved and replaced with the next set of stacking stations. The replacement of stacking stations wastes a lot of time and causes the device to stop, thereby reducing the stacking efficiency of cable trays. To address this, the present invention provides a cable tray stacking machine. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0006] The technical solution adopted by the present invention to solve its technical problem is as follows: The cable tray palletizing machine of the present invention includes a feeding mechanism for conveying cable trays, a translation mechanism is provided on the feeding mechanism, a palletizing mechanism for picking up and placing cable trays is provided on the translation mechanism, two sets of palletizing stations are symmetrically arranged in front of the feeding mechanism, each palletizing station includes a frame, two sets of transmission shafts rotatably mounted on the frame, sprockets mounted on the transmission shafts, both sets of sprockets meshing with chains, a number of pairs of limiting members distributed on the chain, and a motor fixedly mounted on one side of the frame for driving a set of transmission shafts, each pair of limiting members consists of two, and the bottom of the limiting members is fixedly connected to the chain; The chain-driven circular motion station switching allows the palletizing mechanism to automatically move out of the full-load station and into the empty station after palletizing is completed. This enables the three processes of palletizing, bundling, and hoisting to be carried out simultaneously. When the palletizing mechanism is working at the front end, the bundling and hoisting at the rear end do not interfere with each other, greatly improving the palletizing efficiency of cable trays.

[0007] Preferably, a support bar for supporting the chain is fixedly installed on the other side of the frame, and the support bar is slidably connected to the chain; When the cable tray is placed on the chain, the support bar supports that section of the chain. When the chain moves in a circular motion, the chain slides along the support bar, making the chain run more stably.

[0008] Preferably, the palletizing station also includes a material blocking mechanism, which includes a rotating shaft rotatably installed in a limiting member. The rotating shaft is fixedly installed with a stop bar for limiting the cable tray. One end of the stop bar is provided with a rotation damper, which is embedded in the limiting member. The stop bar is parallel to the cable tray. Before stacking the cable trays, manually flip the stop bar to keep it perpendicular to the cable trays. Then, place the cable trays between the cable trays. When moving the cable trays quickly, the cable tray limit will prevent the cable trays from tipping over.

[0009] Preferably, the material blocking mechanism further includes a first gear, which is fixedly mounted on a rotating shaft, and a second gear meshing with the first gear. The second gear is rotatably mounted on a fixed shaft, one end of which is fixedly connected to the inner wall of a limiting member, meshing with a rack of the second gear, and a movable plate fixedly connected to the lower end of the rack. A spring is provided on one end of the movable plate, and a pressure rod is fixedly connected to the bottom of the movable plate. A through hole is provided at one end of the movable plate, and a guide post is slidably connected to the through hole. The spring is sleeved on the guide post, and the guide post is fixedly mounted inside the limiting member. A guide hole is provided at the bottom of the limiting member, and the pressure rod is slidably connected to the guide hole. The stacking station includes a guide plate, both ends of which are rotatably connected to the ends of two sets of transmission shafts. A roller is rotatably mounted on the lower end of the pressure rod, and the roller is rotatably connected to the outer ring of the guide plate. The outer ring of the guide plate is composed of a first annular surface, a second annular surface, and an inclined surface. The inclined surface is used to push the roller. By setting a material blocking mechanism, the blocking lever can be automatically opened and closed, which not only improves the automation rate of the device, but also further improves the efficiency of the entire cable tray stacking.

[0010] Preferably, the stop bar is provided with a mounting groove, and several sets of pulleys are rotatably installed in the mounting groove at equal intervals; When the cable tray is placed or removed between the two sets of stops, the side of the cable tray moves along the pulley, and the side of the cable tray drives the pulley to rotate. The rotation of the pulley reduces the friction between the side of the cable tray and the stops, preventing excessive friction from leaving scratches on the side of the cable tray and ensuring the quality of the cable tray.

[0011] The beneficial effects of this invention are as follows: 1. The chain-driven circular motion station switching mechanism automatically moves the palletizing mechanism out of the full-load station and into the empty station after the palletizing is completed. This allows the three processes of palletizing, bundling, and hoisting to be carried out simultaneously. When the palletizing mechanism is working at the front end, the bundling and hoisting at the rear end do not interfere with each other, which greatly improves the palletizing efficiency of cable trays.

[0012] 2. Before stacking cable trays, manually flip the stop bar to keep it perpendicular to the cable trays. Then, place the cable trays between the cable trays. When moving the cable trays quickly, the cable tray limit will prevent the cable trays from tipping over.

[0013] 3. During the process of moving the material blocking mechanism to the stacking position, the rollers on the material blocking mechanism will first roll along the second annular surface. Then, the rollers will roll to the inclined surface, where the inclined surface will push the rollers, causing the rollers to drive the pressure rods to move along the guide holes towards the rack. Next, the pressure rods will push the movable plate along with the rack. During this process, the movable plate slides along the two sets of guide posts and compresses the spring. Simultaneously, the moving rack drives the second gear to rotate. The second gear, through the first gear, drives the rotating shaft and the stop rod to rotate together until the rollers roll to the first annular surface. When the material blocking mechanism, along with the cable... When the cable tray moves from the full-load station to the empty station, the rollers roll on the first annular surface, keeping the stop bar perpendicular to the cable tray. This limits the cable tray's movement and prevents it from tipping over. When the stop mechanism moves out of the empty station, the rollers roll from the first annular surface to the second annular surface. Under the spring's rebound force, the stop bar rotates back, remaining parallel to the cable tray. Therefore, by setting the stop mechanism, the stop bar can be automatically opened and closed, improving not only the automation rate of the device but also the overall efficiency of stacking the cable trays.

[0026] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0027] Example 1: As Figures 1 to 4 As shown in the embodiment of the present invention, a cable tray palletizing machine includes a feeding mechanism 1 for conveying cable trays 4, a translation mechanism 2 on the feeding mechanism 1, and a palletizing mechanism 3 on the translation mechanism 2 for picking up and placing cable trays 4. Two sets of palletizing stations 5 are symmetrically arranged in front of the feeding mechanism 1. Each palletizing station 5 includes a frame 501, two sets of drive shafts 502 rotatably mounted on the frame 501, sprockets 503 mounted on the drive shafts 502, both sets of sprockets 503 meshing with chains 504, a plurality of pairs of limiting members 505 distributed around the chains 504, and a motor 506 fixedly mounted on one side of the frame 501 for driving a set of drive shafts 502. Each pair of limiting members 505 consists of two, and the bottom of each limiting member 505 is fixedly connected to the chain 504.

[0028] Specifically, in the initial state, the palletizing mechanism 3 is located directly above the feeding mechanism 1, with... Figure 1 The middle arrow indicates the stacking position of cable tray 4. Initially, a pair of limiting members 505 are located at the stacking position on the stacking station 5. When cable tray 4 needs to be stacked, the feeding mechanism 1 transports the cable tray 4 to below the stacking mechanism 3. Then, the stacking mechanism 3 picks up the cable tray 4 and, via the translation mechanism 2, places it into the stacking position on the stacking station 5. The end of the cable tray 4 is positioned between the pair of limiting members 505, and the cable tray 4 is located on the chain 504. The material handling mechanism 1, the translation mechanism 2, and the stacking mechanism 3 work together to repeatedly perform the above operations, stacking multiple sets of cable trays 4 at the designated positions. After a certain number of cable trays 4 are stacked at the positions, two sets of motors 506 on the two stacking stations 5 are simultaneously activated. Motors 506 drive corresponding drive shafts 502 to rotate, drive shafts 502 drive sprockets 503 to rotate, and sprockets 503 drive chains 504 along with several pairs of limiting members 505 in a circular motion. Figure 2 The direction indicated by the middle arrow is the direction of circular motion. At the same time, the stacked cable tray 4 moves together with the chain 504 and the limiting member 505 until the next pair of limiting members 505 moves to the stacking position. At this time, the cable tray 4 is placed in the stacking position. The workers bundle and lift the stacked cable tray 4, and repeat the above operation. Compared with the existing technology, the circular motion station switching driven by the chain 504 automatically moves out of the full-load station and into the empty station after the stacking is completed, so that the three processes of stacking, bundling and lifting can be carried out simultaneously. When the stacking mechanism 3 is working at the front end, the bundling and lifting at the rear end do not interfere with each other, which greatly improves the stacking efficiency of the cable tray 4.

[0029] Furthermore, a support bar 507 for supporting the chain 504 is fixedly installed on the other side of the frame 501, and the support bar 507 is slidably connected to the chain 504.

[0030] Specifically, when the cable tray 4 is placed on the chain 504, the support bar 507 supports the chain 504 in that section. When the chain 504 moves in a circular motion, the chain 504 slides along the support bar 507, making the chain 504 run more stably.

[0031] like Figure 5 and Figure 6 As shown, the palletizing station 5 also includes a material blocking mechanism 508. The material blocking mechanism 508 includes a rotating shaft 5081, which is rotatably installed in the limiting member 505. The rotating shaft 5081 is fixedly installed with a stop bar 5082 for limiting the cable tray 4. One end of the stop bar 5082 is provided with a rotation damper, which is embedded in the limiting member 505.

[0032] Specifically, during the process of moving the stacked cable tray 4 from the full-load station to the empty station, if the cable tray 4 moves too fast, it will tip over when it stops at the empty station due to inertia. To ensure that the stacked cable tray 4 does not tip over, the moving speed of the cable tray 4 needs to be reduced, but this will affect the overall stacking efficiency of the cable tray 4. In the initial state, the stop bar 5082 is parallel to the cable tray 4. Before stacking the cable tray 4, manually flip the stop bar 5082 to keep it perpendicular to the cable tray 4. Then, place the cable tray 4 between the cable trays. When the cable tray 4 is moved quickly, the cable tray 4 will be prevented from tipping over due to the limit of the cable tray 4.

[0033] Example 2: Figures 7 to 10 As shown in the comparative embodiment one, another embodiment of the present invention is as follows: the material blocking mechanism 508 further includes a first gear 5083, which is fixedly mounted on the rotating shaft 5081. A second gear 5084 meshes with the first gear 5083. The second gear 5084 is rotatably mounted on a fixed shaft 5085. One end of the fixed shaft 5085 is fixedly connected to the inner wall of the limiting member 505 and meshes with the rack 5086 of the second gear 5084. A movable plate 5087 is fixedly connected to the lower end of the rack 5086. A spring 5088 is provided on one end of the movable plate 5087. A pressure rod 5089 is fixedly connected to the bottom of the movable plate 5087. One end of the movable plate 5087 has a through-hole. Hole 871, through hole 871 is slidably connected to guide post 872, spring 5088 is sleeved on guide post 872, guide post 872 is fixedly installed in limit member 505, limit member 505 has guide hole 5051 at bottom, pressure rod 5089 is slidably connected to guide hole 5051, stacking station 5 includes guide plate 509, the two ends of guide plate 509 are respectively rotatably connected to the ends of two sets of transmission shafts 502, the lower end of pressure rod 5089 is rotatably installed with roller 891, roller 891 is rotatably connected to the outer ring of guide plate 509, the outer ring of guide plate 509 is composed of first annular surface 5091, second annular surface 5092, and inclined surface 5093, inclined surface 5093 is used to push roller 891.

[0034] Specifically, the aforementioned lever 5082 requires manual opening and closing by staff, which not only reduces the automation rate of the device but also reduces the efficiency of the entire stacking of the cable tray 4. During the process of moving the material blocking mechanism 508 to the stacking position, the roller 891 on the material blocking mechanism 508 first rolls along the second annular surface 5092. Then, the roller 891 rolls to the inclined surface 5093, which pushes the roller 891, causing the roller 891 to drive the pressure rod 5089 to move along the guide hole 5051 towards the rack 5086. Then, the pressure rod 5089 pushes the movable plate 5087 and the rack 5086 to move together. During this process, the movable plate 5087 slides along the two sets of guide posts 872 and compresses the spring 5088. At the same time, the moving rack 5086 drives the second gear 5084 to rotate. The second gear 5084 drives the rotating shaft 5081 and the stop rod 5082 to rotate together through the first gear 5083 until the roller 891 rolls... When the material blocking mechanism 508 moves from the full-load position to the empty position along with the cable tray 4, the roller 891 rolls on the first annular surface 5091, keeping the stop bar 5082 perpendicular to the cable tray 4. This achieves the limitation of the stop bar 5082 on the cable tray 4, preventing the cable tray 4 from tipping over. When the material blocking mechanism 508 moves out of the empty position, the roller 891 rolls from the first annular surface 5091 to the second annular surface 5092. Under the rebound force of the spring 5088, the stop bar 5082 rotates back and remains parallel to the cable tray 4. Therefore, by setting the material blocking mechanism 508, the stop bar 5082 can be automatically opened and closed, which not only improves the automation rate of the device but also further improves the efficiency of the entire stacking of the cable tray 4.

[0035] Furthermore, the stop bar 5082 is provided with a mounting groove 821, and several sets of pulleys 822 are rotatably installed in the mounting groove 821 at equal intervals.

[0036] Specifically, when the cable tray 4 is placed between the two sets of stop bars 5082, the side of the cable tray 4 will move against the pulley 822, and the side of the cable tray 4 will drive the pulley 822 to rotate. The rotation of the pulley 822 reduces the friction between the side of the cable tray 4 and the stop bar 5082, so as to avoid excessive friction and leave scratches on the side of the cable tray 4, thus ensuring the quality of the cable tray 4.

[0037] Working Principle: The cable tray 4 is conveyed to the palletizing mechanism 3 by the feeding mechanism 1. The palletizing mechanism 3 then picks up the cable tray 4 and places it onto the palletizing station 5 via the translation mechanism 2. The end of the cable tray 4 is positioned between a pair of limiting members 505 and rests on the chain 504. The feeding mechanism 1, translation mechanism 2, and palletizing mechanism 3 work together to repeat this process multiple times, stacking multiple sets of cable trays 4 at the designated positions. After a certain number of cable trays 4 have been stacked, two sets of motors 506 on the two palletizing stations 5 are simultaneously activated. The motors 506 drive the corresponding drive shafts 502 to rotate, which in turn drive the sprockets 503. The sprockets 503 then drive the chain 504, along with several pairs of limiting members 505, in a circular motion. Figure 2 The direction indicated by the middle arrow is the direction of circular motion. At the same time, the stacked cable tray 4 moves together with the chain 504 and the limiting piece 505 until the next pair of limiting pieces 505 moves to the stacking position. At this time, the cable tray 4 is placed in the stacking position. The staff bundles and hoists the stacked cable tray 4, and repeats the above operation. During the process of moving the material blocking mechanism 508 to the stacking position, the roller 891 on the material blocking mechanism 508 first rolls along the second annular surface 5092. Then, the roller 891 rolls to the inclined surface 5093, which pushes the roller 891, causing the roller 891 to drive the pressure rod 5089 to move along the guide hole 5051 towards the rack 5086. Then, the pressure rod 5089 pushes the movable plate 5087 together with the rack 5086 to move. During this process, the movable plate 5087 slides along the two sets of guide posts 872 and compresses the spring 5088. At the same time, the moving rack 5086 drives the second gear 5084 to rotate. The second gear 5084, through the first gear 5086, rotates the second gear 5084. 083 drives the rotating shaft 5081 to rotate together with the stop rod 5082 until the roller 891 rolls to the first annular surface 5091. When the stop mechanism 508 and the cable tray 4 move out of the full-load station and into the empty station, the roller 891 rolls on the first annular surface 5091, keeping the stop rod 5082 perpendicular to the cable tray 4, thus limiting the cable tray 4 and preventing the cable tray 4 from tipping over. When the stop mechanism 508 moves out of the empty station, the roller 891 rolls from the first annular surface 5091 to the second annular surface 5092. Under the rebound force of the spring 5088, the stop rod 5082 rotates back and remains parallel to the cable tray 4.
