Description

Technical Field

[0001] This utility model relates to the field of mechanical design technology, specifically to an aluminum rod palletizing machine. Background Technology

[0002] As an auxiliary equipment for packaging and bundling in the automated production line of the casting workshop, aluminum rod palletizing machines are required to automatically feed, count, and separate aluminum rods with high external turning precision and straightening, and automatically stack them to meet bundling and packaging needs. Due to transportation and cost control, steel strapping, aluminum strapping, and multi-layer PET parallel bundling are the primary methods used. Most operations involve manual labor and crane coordination. Because of the wide variety of rod diameters and stacking types, manual calibration of the aluminum rod end faces is necessary, which involves a certain degree of labor intensity and poses risks of mechanical injury. Improper operation can also damage the surface of the aluminum rods. Utility Model Content

The shift fork between the limiting part and the pushing part has an inwardly concave arc-shaped structure. When the piston rod of the first cylinder extends, the limiting part of the shift fork flips upward and is in a raised state, stopping the aluminum rod located behind the shift fork, so that the foremost aluminum rod is located in the concave part of the shift fork. When the piston rod of the first cylinder retracts, the pushing part of the shift fork flips upward and pushes the aluminum rod located in the concave part of the shift fork toward the front end of the support bracket.

[0009] The alignment device includes an alignment mechanism, which has two sets of symmetrically arranged on both sides of the support bracket between the shift fork and the front baffle. The alignment mechanism includes a roller, an alignment bracket, a second cylinder, and a push plate.

[0022] The first limiting bolt is set on the carriage base and located above the rear of the lifting arm. When the rear of the carriage base contacts the first limiting bolt, the lifting arm located in front of the hinge position with the carriage base is in a horizontal state.

A limiting baffle is provided on the lifting arm located in front of the hinge position with the slide base.

[0044] In the description of this utility model, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0045] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0046] like Figures 1 to 8As shown, the aluminum bar palletizing machine includes a feeding device 100 and an alignment device 200. The feeding device 100 is used to temporarily store the aluminum bars fed by the robotic arm, feed the aluminum bars to the alignment device 200, and count the aluminum bars fed to the alignment device 200. The alignment device 200 is used to align the end faces of the aluminum bars.

[0047] The feeding device 100 includes a support bracket 101, a guide plate 102, and an intermediate shifting fork mechanism 103.

[0048] The upper end of the support bracket 101 is provided with a crossbeam, and the guide plate 102 is set on the crossbeam at the upper end of the support bracket 101. The upper surface of the guide plate 102 has a certain slope, specifically, the end of the guide plate 102 away from the alignment device 200 is higher, and the end closer to the alignment device 200 is lower, so that the aluminum rod conveyed and placed on the guide plate 102 by the robot can roll toward the alignment device 200.

[0049] The intermediate shift fork mechanism 103 includes a first cylinder 105, a synchronous shaft 106, a first connecting rod 107, and a shift fork 108.

[0050] The end of the synchronous shaft 106 is hinged to the support bracket 101, so that the synchronous shaft 106 can rotate relative to the support bracket 101. The synchronous shaft 106 is arranged longitudinally, and its axis is parallel to the axis of the aluminum rod.

[0051] The first cylinder 105 is fixedly mounted on the support bracket 101. The end of the piston rod of the first cylinder 105 is hinged to one end of the first connecting rod 107, and the other end of the first connecting rod 107 is fixedly connected to the synchronous shaft 106. The extension or retraction of the piston rod of the first cylinder 105 drives the rotation of the synchronous shaft 106.

[0052] The shift fork 108 is a plate-shaped mechanism. The middle part of the shift fork 108 is sleeved on the synchronous shaft 106 and fixedly connected to the synchronous shaft 106. The rotation of the synchronous shaft 106 drives the shift fork 108 to rotate. The shift fork 108 is provided with a limiting part 112 for stopping the aluminum rod and a pushing part 113 for pushing the aluminum rod toward the alignment device 200. The part of the shift fork 108 between the limiting part 112 and the pushing part 113 is a concave part with an inward arc-shaped structure.

[0053] like Figure 9 As shown, when the aluminum rod is placed on the guide plate 102, it will roll to the position of the shift fork 108. The piston rod of the first cylinder 105 is in the extended state. The initial position of the shift fork 108 is that the limiting part 112 is in the vertically raised state. The aluminum rod at the foremost end is blocked by the limiting part 112 of the shift fork 108. At this time, the aluminum rod is located in the concave position between the limiting part 112 and the pushing part 113 of the shift fork 108.

[0054] When the aluminum rod at the foremost position needs to be pushed forward, the piston rod of the first cylinder 105 retracts, causing the shift fork 108 to rotate clockwise. The limiting part 112 of the shift fork 108 flips downward, and the pushing part 113 of the shift fork 108 flips upward, pushing the aluminum rod located in the concave part of the shift fork 108 towards the front end of the support bracket 101. The front end of the support bracket 101 is provided with a vertically arranged front baffle 104 to limit the further forward movement of the aluminum rod.

[0055] like Figure 4 As shown, Figure 10 The outer edge of the pushing part 113 of the shift fork 108 is a convex arc structure, so that when the pushing part 113 of the shift fork 108 rotates clockwise and drives the aluminum bar at the front end to move forward, the pushing part 113 of the shift fork 108 can stop the aluminum bar located on the rear side. When the shift fork 108 rotates clockwise, the aluminum bar located on the rear side is in continuous contact with the convex arc structure of the pushing part 113. The design of the convex arc structure can avoid scratching the aluminum bar.

[0056] By controlling the retraction distance of the first cylinder 105, the aluminum rod at the foremost end rolls forward past the shift fork 108. Then, the piston rod of the first cylinder 105 extends, causing the limiting portion 112 of the shift fork 108 to flip upwards, blocking the aluminum rod at the rear and causing it to roll to the concave position of the shift fork 108. The above steps are repeated to feed a predetermined number of aluminum rods to the front end of the support bracket 101.

[0057] In the above structure, it should be ensured that the height of the limiting part 112 and the pushing part 113 of the shift fork 108 after being raised is higher than the height of the guide plate 102.

[0058] The alignment device 200 includes an alignment mechanism 201, which has two sets of symmetrically arranged on both sides of the support bracket 101 between the shift fork 108 and the front baffle 104.

[0059] The alignment mechanism 201 includes a roller 202, an alignment bracket 203, a second cylinder 204, and a push plate 205.

[0060] The idler roller 202 is located at one end of the alignment bracket 203 near the support bracket 101. The axis of the idler roller 202 is perpendicular to the axis of the aluminum rod. The upper end of the idler roller 202 is slightly higher than the upper end of the crossbeam of the support bracket 101 by 1-2 mm, so that the aluminum rod can be smoothly rolled onto the idler roller 202 by the mechanism of the shift fork 108.

[0061] The second cylinder 204 is fixedly mounted on the end of the alignment bracket 203 away from the bearing bracket 101, and the push plate 205 is mounted on the end of the piston rod of the second cylinder 204.

[0062] When the aluminum rod needs to be aligned, the piston rods of the second cylinders 204 of the two alignment mechanisms 201 simultaneously drive the push plates 205 to extend, so that the two push plates 205 move toward the aluminum rod and clamp the aluminum rod to ensure that the two ends of the aluminum rod are aligned. The setting of the rollers 202 can avoid friction between the surface of the aluminum rod and the support, and at the same time, it can achieve the technical effect of aligning the ends of the aluminum rod by applying a small thrust of the second cylinders 204.

[0063] The above settings enable the counting, feeding, and alignment of aluminum bars without manual operation, and prevent surface damage during the alignment process.

[0064] As a supplement to the above technical solution, the alignment device 200 also includes a guide shaft 206 and a front stop block 207.

[0065] The guide shaft 206 is mounted on the alignment bracket 203 and located on its side. The push plate 205 of the alignment device 200 has a through hole for the guide shaft 206 to pass through. The guide shaft 206 passes through the through hole in the push plate 205, providing guidance for the movement of the push plate 205. A front stop 207 is provided at the front of the guide shaft 206. The front stop 207 is used to limit the movement of the push plate 205. The distance between the front stops 207 on the two sets of alignment devices 200 is the same as the length of the aluminum rod. This prevents one set of push plates 205 from moving forward too far, causing the entire aluminum rod to shift.

[0066] As a preferred embodiment of this utility model, the shift fork 108 mechanism further includes a first synchronous link 109, a second synchronous link 110, and a stop arm 111.

[0067] The first end of the first synchronous link 109 is fixedly connected to the synchronous shaft 106, the second end of the first synchronous link 109 is hinged to the first end of the second synchronous link 110, the second end of the second synchronous link 110 is hinged to the middle of the stop arm 111, and the lower end of the stop arm 111 is hinged to the crossbeam of the bearing bracket 101. The stop arm 111 is located in front of the shift fork 108.

[0068] The length direction of the first synchronous link 109 is perpendicular to the length direction of the limiting part 112 of the shift fork 108. During the process of the shift fork 108 rotating counterclockwise and the limiting part 112 flipping upward, the synchronous shaft 106 drives the first synchronous link 109 and the second synchronous link 110 to pull the stop arm 111 upward and flip it into a vertical state. The stop arm 111 is vertical to limit the aluminum rod rolling onto the idler roller 202 and prevent it from rolling towards the shift fork 108.

[0069] As a preferred technical solution of this utility model, it also includes a lifting telescopic fork 300 and an aluminum bundle transfer vehicle 400.

[0070] The lifting telescopic fork 300 includes a lifting frame 301, a horizontal guide rail 302, a vertical guide rail 303, a lifting slide 304, a third cylinder 305, a fourth cylinder 306, a synchronous sprocket 307, a guide wheel 308, and a chain.

[0071] The transverse guide rail 302 and the third cylinder 305 are both located at the bottom of the bearing space. The third cylinder 305 is located on the rear side of the transverse guide rail 302. The lifting frame 301 is located on the transverse guide rail 302. The piston rod of the third cylinder 305 is connected to the lifting frame 301 and is used to drive the lifting frame 301 to slide on the transverse slide rail in the direction toward or away from the aluminum bundle transfer vehicle 400.

[0072] The lifting frame 301 has a vertically arranged vertical guide rail 303 at its longitudinal end, and the lifting slide 304 is mounted on the vertical guide rail 303. The upper end of the vertical guide rail is provided with a guide wheel 308, and the synchronous sprocket 307 is mounted on the lifting frame 301 and located below the guide wheel 308.

[0073] There are two vertical guide rails 303 located on the same side. A rotating shaft is connected between the upper ends of the two vertical guide rails 303. A guide wheel 308 is sleeved on the rotating shaft and fixedly connected to the rotating shaft. The rotating shaft is hinged to the side surface of the guide rail.

[0074] The fourth cylinder 306 is mounted on the lifting frame 301. One end of the chain is connected to the end of the piston rod of the fourth cylinder 306, and the other end of the chain passes over the bottom of the synchronous sprocket 307, then passes over the top of the guide wheel 308, and connects to the upper end of the lifting slide 304. The extension of the piston rod of the fourth cylinder 306 drives the lifting slide 304 to descend, and the retraction of the piston rod drives the lifting slide 304 to rise. The lifting slide 304 is located between the roller 202 of the alignment mechanism 201 and the support bracket 101.

[0075] Both ends of the lifting frame 301 in the longitudinal direction are provided with a set of vertical guide rails. Correspondingly, the fourth cylinder 306, chain, synchronous sprocket 307, and guide wheel 308 are provided in two sets. The aluminum rod is lifted and lowered by the two sets of lifting frames 301.

[0076] The aluminum bundle transfer vehicle 400 is located on the front side of the support bracket 101.

[0077] After the alignment device 200 completes the alignment of the aluminum rod, the fourth cylinder 306 drives the lifting slide 304 to rise and lift the aluminum rod. Then, the piston rod of the third cylinder 305 extends, driving the lifting frame 301 to move towards the side of the aluminum bundle transfer vehicle 400. When it moves above the aluminum bundle transfer vehicle 400, the fourth cylinder 306 drives the lifting slide 304 to descend, causing the aluminum rod to fall onto the aluminum bundle transfer vehicle 400. Subsequently, the third cylinder 305 and the fourth cylinder 306 retract, causing the supporting lifting slide 304 and the lifting frame 301 to reset.

[0078] As a preferred technical solution of this utility model, the lifting slide 304 includes a slide base 310, a lifting swing arm 311, a first limiting bolt 312, a second limiting bolt 313, a limiting connecting rod 314, and a limiting baffle 315.

[0079] The carriage base 310 is mounted on the vertical guide rail, and the middle part of the lifting arm 311 away from the aluminum bundle transfer vehicle 400 is hinged to the carriage base 310, so that the lifting arm 311 can be flipped relative to the carriage base 310. Figure 7 As shown, the lifting arm 311 is hinged to the carriage base 310 at a position on the rear side of the middle of the lifting arm 311, so that the center of gravity of the lifting arm 311 is located on the front side of the hinge position.

[0080] The first limiting bolt 312 is disposed on the carriage base 310 and located above the rear of the lifting arm 311. When the rear of the carriage base 310 contacts the first limiting bolt 312, the front of the lifting arm 311 is in a horizontal state.

[0081] The limiting baffle 315 is disposed on the upper front surface of the lifting arm 311. The limiting connecting rod 314 is disposed on the upper end of the vertical guide rail 303, and the second limiting bolt 313 is disposed on the limiting connecting rod 314 and located above the end of the lifting arm 311 away from the aluminum bundle transfer vehicle 400. The lower end of the second limiting bolt 313 is located below the lower end of the first limiting bolt 312. When the lifting arm 311 is driven to rise by the fourth cylinder 306, and the end of the lifting arm 311 contacts the second limiting bolt 313, the lifting arm 311 is tilted as a whole, in a state of left lower and right higher. The limiting baffle 315 is located on the left side of the aluminum rod and is used to restrict the aluminum rod from falling off and limit the aluminum rod. Through the above settings, when the lifting arm 311 is raised and moves towards the aluminum bundle transfer vehicle 400, the risk of the aluminum rod falling off the front end of the lifting arm 311 is prevented.

[0082] Preferably, a wear-resistant plate 309 is provided on the lifting arm 311 located in front of the limiting baffle 315. The wear-resistant plate 309 is used to prevent wear on the lifting arm 311.

[0083] As a supplement to the technical solution of this utility model, the aluminum bundle transfer vehicle 400 includes a transfer vehicle transverse slide rail 401, a transfer vehicle bracket 402, a stop bar 403, a lifting platform 404, and a fifth cylinder 405.

[0084] The transverse slide rail 401 of the transfer vehicle is located on the front side of the material feeding device 100, and the transfer vehicle bracket 402 is located on the transverse slide rail 401 of the transfer vehicle. The transfer vehicle bracket 402 is driven to slide on the transverse slide rail 401 of the transfer vehicle by a chain-driven transverse sliding table mechanism.

[0085] Both ends of the transfer vehicle support 402 are equipped with a fifth cylinder 405, and the lifting platform 404 is mounted on the piston rod of the fifth cylinder 405. The lifting platform 404 is driven to move up and down by the fifth cylinder 405.

[0086] Both the front and rear ends of the transfer vehicle support 402 are equipped with stop bars 403. The lifting telescopic fork 300 places the aluminum rod between the two sets of stop bars 403, and the end of the aluminum rod rests on the lifting platform 404. The stop bars 403 are used to limit the aluminum rod and prevent it from falling off the transfer vehicle support 402.

[0087] Once the number of aluminum rods stacked on the transfer vehicle bracket 402 reaches the set value, the transfer vehicle bracket 402 moves laterally to the packaging table, where staff package the aluminum rods.

[0088] like Figures 9 to 12 The diagram shown is a schematic diagram of the structure of this utility model in the state of feeding and lifting aluminum rods. Figure 9 The aluminum rods are stopped by the intermediate shift fork mechanism 103 and are stacked behind the intermediate shift fork mechanism 103. Figure 10 The intermediate shift fork mechanism 103 is in a shifting state to move the aluminum bar, causing the aluminum bar to roll to the front side of the intermediate shift fork mechanism 103. Figure 11 The intermediate shift fork mechanism 103 completes the aluminum bar feeding, and all the aluminum bars are piled up on the front side of the intermediate shift fork mechanism 103. Figure 12 After the alignment device 200 completes the alignment of the aluminum rod, the telescopic fork 300 lifts the aluminum rod and moves it to the aluminum bundle transfer vehicle 400.

[0089] The above description is only a preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be included within the protection scope of the present invention.
