Description

Technical Field

[0001] The utility model relates to the technical field of warehousing, in particular to a rotary switch device, and an annular shuttle system applying the rotary switch device. Background Art

[0002] With the increasing demand for automation, the application of automated stereoscopic warehousing is becoming more and more widespread. The ring-through single machine is widely used in the automated stereoscopic warehouse industry due to its strong expandability, high transfer efficiency, and flexible transfer. The conventional annular shuttle system usually refers to setting up a closed loop, and the ring-through single machine reciprocates in one direction (clockwise or counterclockwise) on the annular track to achieve the connection of goods. The ring-through single machine is mostly composed of a double walking motor, a rotating mechanism, a rotating variable pitch mechanism, etc. The double-motor walking wheel system will increase the debugging difficulty of the ring-through single machine, and it is necessary to ensure the synchronization of the two motors. The distribution of the output torque of the two motors when passing through the bend is a technical problem that is more difficult to solve. The rotating mechanism and the rotating rail-changing mechanism on the ring-through single machine are vulnerable parts and are often damaged during actual use and maintenance. After damage, the maintenance cost is high and it will affect the operation of the overall ring-through system. In addition, this type of annular shuttle system cannot automatically run the faulty ring-through single machine to the fault repair area outside the annular track for repair, nor can it schedule the redundant ring-through single machines to the low-efficiency obstacle avoidance area outside the annular track when the system flow is low. Summary of the Utility Model

[0003] The technical problem to be solved by the utility model is to provide a rotary switch device with a simple structure, small floor area, simple installation and maintenance, flexible, stable and reliable operation, and low failure rate. After applying this rotary switch device in the annular shuttle system, the easily damaged rotating mechanism and the rotating rail-changing mechanism on the equipped ring-through single machine can be directly cancelled. This not only reduces the manufacturing cost of the ring-through single machine, but also makes the structure of the ring-through single machine more concise, and can also reduce the horizontal positioning mechanism, reduce the failure rate of the ring-through single machine, improve the stability of the operation of the ring-through single machine, and realize more flexible operation of the annular shuttle system.

[0004] To solve the defects described in the background art, the present application designs a rotary switch device, the structure of which includes: a base and a vehicle body.

[0060] The technical solution of the present utility model will be further described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0061] For the convenience of description, in this embodiment, Figure 1 and Figure 5 the direction shown on the left hand side is defined as "left", and Figure 1 and Figure 5 the direction shown on the right hand side is defined as "right", and Figure 1 and Figure 5 the direction shown on the upper side is defined as "front", and Figure 1 and Figure 5The lower side shown is defined as "rear", and all directional terms such as "left", "right", "front", and "rear" in this text shall be based on this definition. It should be noted that the definition of direction here is only for facilitating the description of the relative positions of various components, and it does not limit the installation direction of the turntable turnout device and the ring shuttle system. Embodiment 1

[0062] In this embodiment, the turntable turnout device described, as Figure 1 and Figure 4 shown, includes: a base 1 and a vehicle body 2. When the turntable turnout device is installed on the foundation, the base 1 is the foundation or a mounting seat structure on the foundation. When the turntable turnout device is installed on the roadway, the base 1 can be a part of the roadway or a separate mounting seat structure, which is not limited here and depends on the specific installation environment and construction requirements. A bearing 21 is embedded in the vehicle body 2, and a support shaft 11 is fixedly arranged on the base 1. In order to improve the reliability of the support shaft 11 fixed on the base 1, an extended strengthening connecting plate 12 is further arranged at the bottom of the support shaft 11, and the extended strengthening connecting plate 12 is fixedly connected with the base 1 by a bolt connection method. The vehicle body 2 is arranged on the support shaft 11 through the bearing 21 and the bearing axial positioning member group 22. The bearing axial positioning member group 22 is used to limit the axial position of the bearing 21, which belongs to conventional technical means, so the bearing axial positioning member group 22 will not be elaborated here. At this time, the vehicle body 2 can rotate through the bearing 21 under the action of an external force. Two guide rails 23 are fixedly arranged on the vehicle body 2. The two guide rails 23 are parallel to each other and are symmetrically distributed on both sides of the center of the vehicle body 2. The ends of the two guide rails 23 are arc-shaped curved surfaces 24, and the arc-shaped curved surfaces 24 at the four ends of the two guide rails 23 are all on the same imaginary circumferential surface.

[0063] As Figure 1 and Figure 2 shown, at the bottom of each end of each guide rail 23, an end support wheel 25 is respectively arranged. When the vehicle body 2 swings around the axis of the support shaft 11, each end support wheel 25 is in rolling contact with the base 1 and is used to support the corresponding guide rail 23. In addition, on the basis of the above, in this embodiment, a middle support wheel 26 is arranged at the bottom of the middle section of each guide rail 23. Each middle support wheel 26 passes through the hollow of the vehicle body 2 and contacts the base 1, and when the vehicle body 2 swings around the axis of the support shaft 11, each middle support wheel 26 is in rolling contact with the base 1 and is also used to support the corresponding guide rail 23.

[0064] A driving device for driving the vehicle body 2 to swing around the axis of the support shaft 11 is arranged on the base 1, as Figure 1 , Figure 2 and Figure 3As shown in the figure, the structure of the driving device in this embodiment is as follows: The motor 3 is installed on the base 1 through the motor support 31. A driving gear 32 is fixedly arranged on the output shaft of the motor 3. An arc-shaped rack 33 meshing with the driving gear 32 is arranged on the vehicle body 2. By rotating the motor 3 forward or backward, the vehicle body 2 can swing clockwise or counterclockwise around the axis of the support shaft 11, thereby changing the directions of the two guide rails 23 on the vehicle body 2 and achieving the purpose of docking with tracks in different directions.

[0065] The turntable type turnout device with the above structure has the advantages of simple structure, small floor area, simple installation and maintenance, flexible, stable and reliable operation, and low failure rate. Embodiment 2

[0071] In the ring shuttle system using the rotary switch device, when the ring shuttle single machine runs to the corresponding rotary switch device, the direction of the ring shuttle single machine can be changed through this rotary switch device.

In addition, the overall occupied space is also reduced, which helps to improve the land use rate.

[0080] The position on the first straight track 4 that is front and back relative to the seventh rotary switch device 67 is truncated to form a third installation space. The position on the first straight track 4 that is front and back relative to the eighth rotary switch device 68 is truncated to form a fourth installation space, thereby segmenting the first straight track 4 into a fourth segmented straight track 41, a fifth segmented straight track 42, and a sixth segmented straight track 43.

[0081] As Figure 11 and Figure 12As shown, the right end portions of the two straight guide rails on the fourth segmented straight track 41, the two end portions of the two straight guide rails on the fifth segmented straight track 42, and the left end portions of the two straight guide rails on the sixth segmented straight track 43 are all eighth arc surfaces 78 that correspond and match the arc surfaces 24 at the ends of the two guide rails 23 on the rotary switch device; the ninth rotary switch device 69 is installed on the base at the third installation space, and the two guide rails 23 on the ninth rotary switch device 69 can be rotated under the drive of the corresponding drive device to be docked with the right end portions of the two straight guide rails on the fourth segmented straight track 41 and simultaneously docked with the left end portions of the two straight guide rails on the fifth segmented straight track 42; the tenth rotary switch device 610 is installed on the base at the fourth installation space, and the two guide rails 23 on the tenth rotary switch device 610 can be rotated under the drive of the corresponding drive device to be docked with the right end portions of the two straight guide rails on the fifth segmented straight track 42 and simultaneously docked with the left end portions of the two straight guide rails on the sixth segmented straight track 43.

[0085] In addition, in order to more intuitively understand whether the ring single machine accurately walks to the designated positions on the two guide rails 23 of the corresponding rotary switch device, an in-place detection switch for detecting that the loop-through single machine walks to the designated positions on the two guide rails 23 of the corresponding rotary switch device can be installed on each rotary switch device. Embodiment Four

[0086] For the ring shuttle system, the industry currently mostly adopts the form of centralized power supply for the full-length path. This form of power supply will cause a relatively large selection of the sliding contact wire, resulting in a certain waste. In addition, the previous power supply state and the operating state of the sliding contact wire were not monitored, and the operating state of the sliding contact wire and the overall power consumption of the loop-through could not be monitored in a timely manner.

[0087] In view of the above defects, in this embodiment, on the basis of Embodiment Two, the form of separate power supply for the long path and the auxiliary ammeter method are adopted. While reducing the selection of the sliding contact wire, the state of each section of the sliding contact wire can be monitored, which is convenient for timely detecting abnormalities of the sliding contact wire. In addition, this method can control the on-off of the power of the sliding contact wire in sections, which is convenient for completing the corresponding maintenance work without affecting the use of other functional areas.

[0088] The specific solution is as follows: As shown in Figure 5 、 Figure 6 and Figure 7 , the sliding contact wire installed on the first straight track 4 is composed of a number of first segmented sliding contact wires 111, and the two adjacent first segmented sliding contact wires 111 are connected by a first line divider 121; the sliding contact wire installed on the second straight track 5 is composed of a number of second segmented sliding contact wires 112, and the two adjacent second segmented sliding contact wires 112 are connected by a second line divider 122.

[0089] The sliding contact wires installed on the guide rails of the four rotary switch devices, namely the first rotary switch device 61, the second rotary switch device 62, the third rotary switch device 63, and the fourth rotary switch device 64, are each composed of two sections of third segmented sliding contact wires 113, and the two sections of third segmented sliding contact wires 113 are connected by a third line divider 123.

[0090] The sliding contact lines on the first docking straight rail 81 and the fourth docking straight rail 84 are each respectively composed of two sections of fourth segmented sliding contact lines 114, and the two sections of fourth segmented sliding contact lines 114 are connected by a fourth line divider 124.

[0091] Each loop-through single machine moves one week in the ring shuttle system, and the carbon brushes at the ends of the current collector arms of each loop-through single machine respectively contact each first segmented sliding contact line 111, each second segmented sliding contact line 112, each third segmented sliding contact line 113, and each fourth segmented sliding contact line 114 once.

[0092] Each section of the first segmented sliding contact line 111, each section of the second segmented sliding contact line 112, each section of the third segmented sliding contact line 113, and each section of the fourth segmented sliding contact line 114 are independently powered, and each section of the first segmented sliding contact line 111, each section of the second segmented sliding contact line 112, each section of the third segmented sliding contact line 113, and each section of the fourth segmented sliding contact line 114 are measured for electrical energy by their respective corresponding electric meters. The signal lines of each electric meter are all connected to a PLC with an alarm device. For the convenience of description, here each section of the first segmented sliding contact line 111, each section of the second segmented sliding contact line 112, each section of the third segmented sliding contact line 113, and each section of the fourth segmented sliding contact line 114 are collectively referred to as a section of sliding contact line. At this time, the PLC can collect the current situation of any section of the sliding contact line in real time. When the current is abnormal, that is, when the electrical energy detected by the electric meter corresponding to this section of the sliding contact line is outside the electrical energy range set in the PLC, the alarm device is started to give an alarm for timely maintenance. In addition, when a certain area is under maintenance, the power supply of this part can be disconnected, and other areas can still be used normally. Embodiment Five

[0093] For the ring shuttle system, the industry currently mostly adopts the form of centralized power supply for the whole path. This kind of power supply form will cause a larger selection of sliding contact lines, resulting in a certain waste. In addition, the previous power supply state and the operation state of the sliding contact lines have not been monitored, and the operation state of the sliding contact lines and the overall power consumption of the loop-through cannot be monitored in time.

[0094] Aiming at the above defects, in this embodiment, on the basis of Embodiment Three, the form of separate power supply for the long path and the auxiliary electric meter method are adopted.
