Description

Technical Field

[0001] The utility model relates to the technical field of stacker track changing mechanisms, and more specifically to a stacker ground track synchronous track changing mechanism. Background Art

[0002] Stereoscopic intelligent storage (AS / RS) is a complex automation system composed of stereoscopic shelves, rail-mounted aisle stackers, in-and-out pallet conveyor systems, size detection barcode reading systems, communication systems, automatic control systems, computer monitoring systems WCS, computer management systems WMS, and other auxiliary equipment such as wire and cable tray distribution cabinets, pallets, adjustment platforms, steel structure platforms, etc. Stereoscopic warehouse equipment can realize warehouse high-rise rationalization, storage and retrieval automation, and simplified operation.

[0003] The stacker fork is the main mechanism for storing and retrieving items. It has an automatic telescopic function. It is directly mounted on the stacker and travels through the lanes between the shelves to complete the automatic storage and retrieval of items. The stacker fork can be connected with the production line system and enterprise management system to achieve information-based and efficient operation and management, which truly saves manpower and energy.

[0004] The traditional stacker track-changing mechanism only has a track-changing mechanism on the stacker ground. The stacker's lower crossbeam guide wheel runs along the track of the ground track-changing mechanism. When the ground track-changing mechanism is close to the turning point, the stacker's overall center of gravity is on the inside of the curved track when turning. The track-changing mechanism is affected by the stacker's running direction and cannot change tracks. In addition, the traditional stacker track-changing mechanism can only change tracks when the stacker is on a straight track as a whole and its center of gravity is at the center of the track, which affects the layout plan and the cargo space in the warehouse area, and wastes land resources.

DETAILED DESCRIPTION

[0024] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the sake of illustration and convenience of description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific purposes.

[0025] like Figure 1-6 As shown, the technical solution of the utility model provides a synchronous track changing mechanism for a stacker 7 and a ground rail 2, including a ceiling rail track changing mechanism 5 arranged on the ceiling rail 1 and a ground rail track changing mechanism 6 arranged on the ground rail 2. The ceiling rail track changing mechanism 5 and the ground rail track changing mechanism 6 act simultaneously when the stacker 7 changes tracks. The ceiling rail track changing mechanism 5 can guide the ceiling rail guide wheel 8 when changing tracks, so as to avoid large shaking or even jamming due to the change in the center of gravity of the stacker 7 when changing tracks. The ground rail track changing mechanism 6 can achieve docking with the straight track 3 and the turning track 4 on the ground rail by switching to meet the track changing requirements. The ground rail guide wheels 9 are stuck on both sides of the ground rail 2 and are in rolling contact with the side of the ground rail 2. The ceiling rail track changing mechanism 5 and the ground rail track changing mechanism 6 cooperate to improve operational stability, improve efficiency, do not affect the cargo space in the warehouse area, and improve land utilization.

[0026] The overhead rail change mechanism 5 includes a linear slide 501, a driving mechanism 1, and a guide member 505 slidably connected to the linear slide 501, wherein the guide member 505 is arranged at the junction of the linear track 3 and the turning track 4, and the guide member 505 is driven by the driving mechanism 1. The guide member 505 can guide the overhead rail guide wheel 8 when changing tracks to ensure that the overhead rail guide wheel 8 is in the correct position, and the position change of the guide member 505 is realized by the driving mechanism 1.

[0027] The driving mechanism 1 includes a driving motor 1 502, a crank disk 503 connected to the output end of the driving motor 1 502, and a pull rod 504 rotatably connected to the crank disk 503, and the other end of the pull rod 504 is rotatably connected to the guide member 505. The pull rod 504 is arranged away from the center of the crank disk 503, and the driving motor 1 502 drives the crank disk 503 to rotate at an angle of 180 degrees. The guide member 505 includes a mounting portion 5051 slidably connected to the linear guide rail 501 and a plate-shaped portion 5052 for limiting, and the guiding is mainly achieved by the plate-shaped portion 5052.

[0028] In the above scheme, the overhead rail track changing mechanism 5 is installed on the H-shaped steel above the overhead rail 1. The mounting portion 5051 of the guide member 505 is slidably connected to the linear guide rail, and can be driven by a driving mechanism 1 to slide back and forth along the linear slide rail 501. The rotation of the driving motor 1 502 will drive the crank disk 503 to rotate, and then drive the pull rod 504 to move. The pull rod 504 also moves linearly with the guide member 505 under the limit of the linear slide rail 501. Each time the driving mechanism rotates 180 degrees, the plate-like portion 5052 has two position states. When the plate-like portion 5052 is close to the turning track 4, it is in a linear track changing state; when the plate-like portion 5052 is close to the linear track 3, it is in a turning track changing state. Figure 5 Shown is the position of the plate-like portion 5052 when in the straight track change state.

[0029] The ground rail track switching mechanism 6 includes a fixed base plate 601, a driving mechanism 2 arranged on the fixed base plate 601, and a track switching assembly connected to the driving mechanism 2, and the track switching assembly includes a mounting plate 607, a curved transition section 608, and a straight section 609. The curved transition section 608 and the straight section 609 are mounted on the mounting plate 607, and the straight section 609 and the curved transition section 608 straight track 3 are respectively connected with the straight track 3 and the turning track 4 on the ground rail 2.

[0030] The second driving mechanism can drive the mounting plate 607 to move, thereby realizing the position change of the straight segment 609 and the curved transition segment 608. The straight segment 609 is docked with the straight track 3 on the ground rail 2, and the stacker 7 can move in a straight line. The curved transition segment 608 is docked with the turning track 4 on the ground rail 2, and the stacker 7 can turn, and the switching is flexible.

[0031] The driving mechanism 2 includes a driving motor 2 602 and a sprocket 1 603 connected by the driving motor 2 602, a sprocket 2 604 arranged on the fixed base plate 601 and a chain 605 meshing with the sprocket 1 603 and the sprocket 2 604, the chain 605 is limited by a guide bar 606, and the track switching component is connected to one side of the chain 605.

[0032] The driving motor 2 602 drives the sprocket 1 603 to rotate, and the sprocket 1 603, the sprocket 2 604 and the chain 605 cooperate, and the mounting plate 607 is connected to one side of the chain 605, and the chain 605 rotates to drive the mounting plate 607 to move, and the position is limited by the limit guide bar during the movement. Four supporting rollers 610 are arranged at the bottom of the mounting plate 607. The arrangement of the supporting rollers 610 can ensure the stable movement of the mounting plate 607 on the one hand, and support the mounting plate 607 on the other hand when the stacker 7 passes by the mounting plate 607 position to prevent the mounting plate 607 from shaking.
