Description

Technical Field

[0001] The utility model belongs to the technical field of palletizing, and in particular relates to a curbstone palletizing machine. Background Art

[0002] Curbstones are block-shaped objects used as boundary stones on the edge of the road. They are the boundaries that distinguish the roadway, sidewalk, green space, isolation belt and other parts of the road on the road. They play a role in ensuring the safety of pedestrians and vehicles and ensuring the neatness of the road edge. At the same time, they can also play a role in beautifying and protecting the road surface. They are used in a large amount in various infrastructure construction such as landscaping, road construction, and old city reconstruction, and have a wide range of applications. With the optimization and upgrading of urban roads and the vigorous development of construction projects, the demand for curbstones has increased year by year, and the requirements and efficiency for the stacking and packaging of curbstones have also become higher and higher.

[0003] The molding method of concrete curbstones is mold pressing molding, which involves filling a mixture of concrete and its components into a molding mold, applying pressure to the molding mold, draining water, and rapidly dehydrating, compressing, and condensing the mixture under pressure in the mold. After demolding and drying, curbstones are obtained. After demolding, the curbstones are relatively scattered and need to be stacked and cured to be completely dry before use.

[0004] At present, the stacking machines for curbstone-type concrete brick products can only stack large flat surfaces, which are not only prone to bumps and collisions that cause secondary cracking and damage to the bricks, but also the curbstones have a large covered surface area after stacking, while the exposed surface area is small, and the maintenance and drying time is long, resulting in a long production cycle for the curbstones and low production efficiency. Utility Model Content

DETAILED DESCRIPTION

[0029] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0030] In the present application, terms such as “first” and “second” are merely used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship of quantity, priority or sequence between these entities or operations.

[0031] Please also read Figures 1 to 6Now, the curbstone stacker provided by the utility model is described. The curbstone stacker comprises a guide rail bracket 5, a traveling trolley 2, a lifting guide mechanism 1 and a product transfer mechanism 4, wherein the traveling trolley 2 is arranged on the guide rail bracket 5 and reciprocates along the guide rail bracket 5; the lifting guide mechanism 1 is arranged on the traveling trolley 2; the lifting guide mechanism 1 comprises a lifting guide rail 110 which can be raised and lowered, and the lifting guide mechanism reciprocates with the traveling trolley 2 at the same time; the product transfer mechanism 4 comprises a transfer base 403, a driving cylinder 404, a rotating frame 407 and a vacuum suction cup 401; the transfer base 403 is connected to the lower end of the lifting guide rail 110, the driving cylinder 404 is connected to the transfer base 403, the rotating frame 407 is rotatably connected to the transfer base 403 at the corner, the first arm of the rotating frame 407 is hinged to the driving cylinder 404, and the second arm of the rotating frame 407 is connected to the vacuum suction cup 401; the extension and retraction of the driving cylinder 404 pushes the rotating frame 407 to drive the vacuum suction cup 401 to realize a 90° flip.

[0032] The curbstone stacking machine provided by the utility model, during stacking, the extension and contraction of the driving cylinder 404 pushes the rotating frame 407 to drive the vacuum suction cup 401 to realize a 90° flip, and the curbstone adsorbed on the vacuum suction cup 401 is flipped 90°, so that the large plane of the curbstone is in a vertical state, and then the curbstone carried by the vacuum suction cup 401 is lifted to a certain height by the lifting guide mechanism 1, and the lifting guide mechanism is also moved to the stacking position with the walking trolley 2, and directly stacked in layers, at this time, the small planes of the curbstone are stacked on each other, and the large plane is exposed to the air, and the contact area between the curbstones after stacking is small, which can improve the effect of curbstone curing and drying, shorten the curing time, and improve the production efficiency of the curbstone; at the same time, the small area contact between the curbstones in an upright state after flipping can effectively prevent the curbstone from secondary damage such as cracking and fragmentation during the stacking process.

[0033] It should be noted that the curbstone stacker provided in the present application is not only suitable for stacking curbstones, but also suitable for other rectangular bricks made of concrete.

[0034] The explanation of the large and small planes of the curbstone is as follows: the curbstone is a rectangular structure, generally with a length, width, and thickness of 75cm×35cm×25cm, the large plane described in this article is 35cm, and the small plane is 25cm. The vacuum suction cup 401 is attached to the large plane of the curbstone, and then flipped 90°, so that the small plane of the curbstone faces downward, and then the small planes are stacked and stacked.

[0035] The first arm and the second arm of the rotating frame 407 form an angle of at least 90°.

[0036] In some embodiments, Figure 5As shown, a support seat 405 is provided on the transfer base 403, a bearing seat 406 is provided on the support seat 405, a support shaft is provided on the bearing seat 406, a corner of the rotating frame 407 is connected to the support shaft, and an avoidance space for the first arm of the rotating frame 407 is formed between the support shaft and the transfer base 403. When the cylinder rod of the driving cylinder 404 is extended, the cylinder rod pushes the first arm of the rotating frame 407 to rotate away from the driving cylinder 404, and the avoidance space allows the first arm to have space to rotate, and the second arm connected to the first arm will rotate in the direction of the driving cylinder 404. When the first arm rotates to be perpendicular to the transfer base 403, the second arm is parallel to the transfer base 403. At this time, the vacuum suction cup 401 is parallel to the large plane of the product. The vacuum suction cup 401 is close to the product and sucked up by the extension and contraction of the height adjustment cylinder 402; when the product transfer mechanism 4 moves synchronously with the lifting guide mechanism and the walking trolley 2, or when the product transfer mechanism 4 moves to the stacking station, the cylinder rod of the driving cylinder 404 is retracted, driving the rotating frame 407 to rotate in the opposite direction until the second arm is in a vertical state, and the product sucked by the vacuum suction cup 401 can be turned 90° so that the small plane of the product faces downward, and then the product is stacked on the next layer of products through the lifting and lifting adjustment of the lifting guide mechanism.
