Description

Technical Field

[0001] The present invention relates to the technical field of automated storage devices, in particular to a flipping device for correcting the position of products in a storage line. Background Art

[0002] Warehousing is one of the important links in production and manufacturing and the circulation of goods, and it is also an important link in logistics activities. When goods are stored in warehouses, it is necessary to ensure that the product is positioned uniformly when the goods are transmitted on the storage line. Therefore, it is necessary to always position the product correctly to avoid skewed transmission of the product, which may cause product displacement or misalignment. If the product is offset during transmission, it will affect the position displacement of the entire process, resulting in the robot being unable to select the product surface to absorb the goods, let alone the robot being able to absorb the goods reliably, which ultimately affects the product loading or packaging. At the same time, in the current storage lines, there is still the problem that the robot can only absorb a single side when absorbing goods. This defect is not conducive to the convenience and efficiency of loading cages, and has poor versatility, affecting work efficiency and economic benefits. Summary of the invention

[0010] Preferably, the rotating alignment component is a rubber-coated bearing, which is vertically mounted on the C-end of the connecting rod via a rotating shaft to form an installation structure in which the rubber-coated bearing rotates around the rotating shaft at the C-end of the connecting rod.

[0011] Preferably, the connecting rod fixing seat is composed of two fixing plates, and two through holes for installing the rotating shaft are arranged at the diagonals, and the two through holes are hingedly connected to the connecting rod B and the connecting rod C respectively.

[0012] Preferably, the roller device includes a straight roller assembly, an inclined roller assembly and a workbench. The workbench is a working frame with the straight roller assembly and the inclined roller assembly mounted on the surface, and a horizontal rotation mechanism and a vertical flipping mechanism mounted on the side.

[0017] The beneficial effects of the present invention are as follows: when transmitting articles on a storage line, the articles first flow through an inclined roller assembly and are rotated and aligned in a horizontal direction by a horizontal rotating mechanism; then, when being transmitted to a straight roller assembly, the articles are vertically flipped and aligned by a vertical flipping mechanism; finally, the articles are grabbed by a robot and caged and boxed; at the same time, the present invention adjusts the product positioning of the storage line to facilitate the grabbing selection of the best suction surface of the cage loading robot, making the suction of articles more reliable, ensuring the stability and efficiency of the cage loading of articles, and realizing the convenience and high efficiency of the cage loading of the cage loading robot; by adjusting the alignment of the products, it is convenient to maximize the utilization of space when loading articles into cages.

The connecting rod structure of the connecting rod power device also performs reciprocating connecting rod motion under the transmission action of the type-one connecting rod. Therefore, when the horizontal rotation drive device exerts an electric drive effect, the linkage rod telescopes and swings with the cylinder fixing seat at the same time, thereby driving the type-one connecting rod and the connecting rod structure as a whole to swing and move back and forth. Since the connecting rod structure performs the connecting rod motion at the same time, the overall motion is connected to realize the reciprocating motion of the electrically driven connecting rod, thereby driving the rubber-coated bearing to rotate and telescope to adjust the product rotation position.

[0019] The vertical flipping mechanism of the present invention can realize the vertical flipping of articles.

First, a linear motion device is installed at the flipping support, and the rotating connecting rod is connected to the rotating connecting rod through a slidable screw nut in the linear motion device, so that the rotating connecting rod can rotate around the screw nut and slide along the screw line with the screw nut; then, the bottom of the flipping fixed base is fixed on the straight roller assembly, and the top is hingedly connected to the flipping support, so that the flipping support can rotate around the flipping fixed base and drive the linear motion device to rotate accordingly; finally, the rotating connecting rod and the flipping fixed base are also rotatably connected, so one end of the rotating connecting rod can rotate around the flipping fixed bottom, and the other end can rotate around the linear motion device, and the three parts move in a continuous manner to form a reciprocating flipping motion; therefore, under the motion support force of the rotating connecting rod and the linear motion device, the flipping support can flip as a whole around the flipping fixed bottom, so that the sponge vacuum suction cup finally absorbs the article and stands up vertically, and the manipulator grabs the article from the sponge vacuum suction cup and further packs it into a cage and box.

[0030] This embodiment mainly consists of three parts: a roller device 1, a horizontal rotation mechanism 2, and a vertical flip mechanism 3. A flow limit blocking cylinder can be set at the straight roller assembly of the roller device, and a blocking component is extended by the flow limit blocking cylinder to assist in positioning the object; wherein:

[0031] 1) The inclined roller assembly 12 of the roller device realizes the function of positioning the objects sideways during transportation;

[0032] 2) The horizontal rotation mechanism 2 can realize the horizontal rotation of the object by 90°. After the rotation is corrected, it is convenient to be transmitted to the straight roller assembly. The horizontal rotation mechanism 2 is installed on the side of the frame of the straight roller assembly. The rubber-coated bearing is arranged on the side of the straight roller assembly under the support of the connecting rod structure, so as to be adjacent to the object being transmitted. When the object hits the rubber-coated bearing, the rubber-coated bearing rotates to drive the object to rotate 90°, thereby realizing the horizontal rotation of the object by 90°; the driving cylinder, the type I connecting rod, the connecting rod A, the connecting rod B, and the connecting rod C are respectively connected by hinges. Under the premise that the driving cylinder provides power, the connecting rod C finally reaches the dead point. The rubber-coated bearing is rotatably installed on the connecting rod C. When the object hits the rubber-coated bearing, a 90-degree horizontal rotation is realized without rotating the object in the correct position. The connecting rod C retracts inward under the power of the driving cylinder;

[0033] 3) The flow direction limiting blocking cylinder is set at the straight roller assembly. When the object is transferred to the straight roller assembly, the flow direction limiting blocking cylinder blocks its forward flow, so that the object stays at the specified position. The flow direction limiting blocking cylinder provides preparation for achieving a vertical 90° flip;

[0034] 4) The vertical flipping mechanism 3 realizes the flipping of the object in the vertical direction, which is convenient and efficient for the robot to suck and put into the cage; the driving motor provides the main force, the screw nut 324 and the linear slide 322 move back and forth along the screw 323 and the linear guide 321, and one end of the rotating connecting rod is connected to the screw nut and the other end is connected to the flipping fixed base, thereby realizing the flipping action, and the sponge vacuum suction cup realizes the action of sucking the object.

[0035] The items first pass through the inclined roller assembly to achieve side positioning. If it is necessary to rotate the items horizontally, the rubber-coated bearing of the horizontal rotating mechanism 2 is extended to rotate the items 90°, and the items are rotated to the correct position and continue to flow backward; and when the items first pass through the straight roller assembly and then through the flow limit blocking cylinder, the flow limit blocking cylinder extends a blocking component to position the items, so that the items stay between the straight roller assemblies, and then the vertical flipping mechanism flips and stands up to absorb the items. Since the items need to be flipped vertically to facilitate the robot to absorb and cage the items, the vertical flipping mechanism sucks the items through the sponge vacuum suction cup, and then the flip support and the sponge vacuum suction cup that sucks the items are flipped until they stand vertically, and the robot grabs the items from the sponge vacuum suction cup to cage and box them.

[0036] The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Technical personnel in this industry can make some deformation and modifications under the inspiration of this technical solution. Any modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
