Description

Technical Field

[0001] This utility model relates to a shuttle vehicle, specifically a shuttle vehicle adaptable to two lengths and multiple widths. Background Technology

[0002] Currently, most shuttles operate with a specific size of tool rack or pallet. However, some manufacturers may have a wider variety of goods, and a single size tool rack or pallet cannot meet their daily stacking needs. Therefore, we are considering developing a shuttle that can accommodate pallets or tool racks of more sizes. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a shuttle car that can adapt to two lengths and multiple widths. This addresses the problem that some customers have multiple sizes of tooling racks, making it impossible for a single conventional shuttle car to transport them.

[0004] To achieve the above technical objectives, the technical solution adopted in this utility model embodiment is as follows: A shuttle adaptable to two lengths and multiple widths includes a high-low chain conveyor and a traveling assembly. The high-low chain conveyor is mounted on the traveling assembly, which is capable of traveling along the length of a ground track. The high-low chain conveyor is used to adjust the position of goods in the width direction of the ground track. A ground end block and a ground barcode scanner are provided on one side of the ground track. The ground end block is used to block the goods on the high-low chain conveyor, and the ground barcode scanner is used to scan the goods to confirm the dimensions of the goods. A ground mesh bridge is provided at one end of the ground track. The ground mesh bridge and the traveling mesh bridge in the traveling assembly are mutually sensed to confirm the accurate position of the traveling assembly.

[0005] Furthermore, the high-low chain conveyor includes several groups of parallel chains, with the groups of chains arranged on planes at different heights.

[0006] Furthermore, the high-low chain conveyor also includes a main beam, a drive station, and an encoder. The main beam is supported by the support column, and a weighing module is provided at the bottom of the support column. The drive station is equipped with a first motor and a first drive shaft. The first motor and the first drive shaft cooperate to drive the chain to move synchronously. The encoder is used to precisely control the running distance of the goods on the chain and to confirm whether the geometric center of the goods coincides with the geometric center of the chain conveyor through a diffuse-reflection switch.

[0007] Furthermore, the high-low chain conveyor also includes a blocking part and a guide frame. The guide frame ensures that the goods are placed centered on the high-low chain conveyor. The blocking part is located on the side of the chain to prevent the goods from rushing out of the high-low chain conveyor.

[0008] Furthermore, the walking assembly includes a walking frame, a second motor, and a second drive shaft. The walking frame is equipped with walking wheels, and the second motor drives the walking wheels to move on the ground track via the second drive shaft.

[0009] Furthermore, the walking assembly also includes a horizontal guide wheel and an end anti-collision device, which are located at the two ends of the walking frame, respectively. The horizontal guide wheel is used to ensure the straightness of the walking assembly.

[0010] Furthermore, the traveling assembly also includes a current collector arm and a sliding contact line. The current collector arm is mounted on the traveling frame. During the travel of the traveling frame, the carbon brush at the end of the current collector arm is always in contact with the conductor of the sliding contact line, thereby supplying power to the entire shuttle.

[0011] Furthermore, the traveling assembly also includes a horizontal addressing device, which includes a deceleration slot switch, a position slot switch, and a limit switch mounted on the traveling frame, as well as a deceleration sensing plate, a position sensing plate, and a limit sensing plate mounted on the ground. The deceleration slot switch and the deceleration sensing plate work together to decelerate the traveling assembly; the position slot switch and the position sensing plate work together to confirm whether the traveling assembly has reached its position; and the limit switch and the limit sensing plate work together to provide final electrical protection for the traveling assembly.

[0012] Furthermore, end blocks are provided at both ends of the ground rail, and buffers are provided on the opposite inner sides of the end blocks.

[0013] The beneficial effects of the technical solution provided by this utility model embodiment are: 1) The shuttle of this utility model accurately positions the pallet or tool rack by blocking the end of the ground, so that the geometric center of the tool rack can always coincide with the geometric center of the shuttle.

[0014] 2) The shuttle of this utility model can ensure that when pallets (or tooling racks) of different widths are connected to the forks, the center of the pallet (or tooling rack) coincides with the center of the upper fork and is accurately placed in the center of the rack.

[0015] 3) The shuttle of this utility model can adapt to two lengths of pallets (or tool racks), giving customers more options. Attached Figure Description

They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the scope of protection of this utility model.

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0031] Example 1 like Figures 1-4 As shown, a shuttle adaptable to two lengths and multiple widths includes a high-low chain conveyor 1 and a traveling assembly 2. The high-low chain conveyor 1 is mounted on the traveling assembly 2, which can travel along the length of a ground track 6. The high-low chain conveyor 1 is used to adjust the position of goods in the width direction of the ground track 6. A ground end block 3 and a ground barcode scanner 4 are provided on one side of the ground track 6. The ground end block 3 is used to block the goods on the high-low chain conveyor 1, and the ground barcode scanner 4 is used to scan the goods to confirm the size of the goods. A ground mesh bridge 5 is provided at one end of the ground track 6. The ground mesh bridge 5 and the traveling mesh bridge 201 in the traveling assembly 2 are mutually sensed to confirm the accurate position of the traveling assembly 2.

[0032] like Figures 5-8 As shown, the high and low chain conveyor 1 includes several sets of parallel chains 11. The sets of chains 11 are arranged on planes at different heights, so that the sets of chains 11 at different heights can hold goods of different lengths.

[0033] The chain 11 is set perpendicular to the length direction of the ground rail 6, and the relative position of the goods and the ground rail 6 can be adjusted during the movement of the chain 11.

[0034] In one implementation, the high-low chain conveyor 1 includes four rows of parallel chains 11, forming two sets of chains 11 with different heights, which can support two lengths of cargo jigs. For example, it can simultaneously support cargo jigs with lengths of 1200mm and 1600mm. The width of the cargo jig is 700-1100mm, and the jig is loaded with goods of different lengths and specifications.

[0035] The high and low chain conveyor 1 also includes a main beam 12, a drive station 14, and an encoder 15. The main beam 12 is supported by a support column 13. A weighing module 16 is provided at the bottom of the support column 13. The drive station 14 is equipped with a first motor 141 and a first drive shaft 142. The first motor 141 and the first drive shaft 142 cooperate to drive the chain 11 to move synchronously. The encoder 15 is used to accurately control the running distance of the goods on the chain 11 and to confirm for the second time whether the geometric center of the goods coincides with the geometric center of the chain conveyor 1 through a reversing switch 17.

[0036] The high-low chain conveyor 1 also includes a blocking part 18 and a guide frame 19. The guide frame 19 ensures that the goods are placed in the center on the high-low chain conveyor 1. The blocking part 18 is provided on the side of the chain 11 to prevent the goods from rushing out of the high-low chain conveyor 1.

[0037] like Figures 9-12 As shown, the walking assembly 2 includes a walking frame 202, a second motor 203, and a second drive shaft 204. The walking frame 202 is equipped with walking wheels 205, and the second motor 203 drives the walking wheels 205 to move on the ground track 6 through the second drive shaft 204.

[0038] The walking assembly 2 also includes a horizontal guide wheel 206 and an end anti-collision device 207. The horizontal guide wheel 206 and the end anti-collision device 207 are located at the two ends of the walking frame 202, respectively. The horizontal guide wheel 206 is used to ensure the straightness of the walking assembly 2.

[0039] The traveling assembly 2 also includes a current collector arm 208 and a sliding contact line 209. The current collector arm 208 is mounted on the traveling frame 202. During the travel of the traveling frame 202, the carbon brush at the end of the current collector arm 208 is always in contact with the conductor of the sliding contact line 209, thereby supplying power to the entire shuttle.

[0040] The traveling assembly 2 also includes a horizontal addressing device, which includes a deceleration slot switch 211, a position slot switch 212, and a limit switch 210 mounted on the traveling frame 202. It also includes a deceleration sensor, a position sensor, and a limit sensor mounted on the ground. The deceleration slot switch 211 and the deceleration sensor work together to decelerate the traveling assembly 2. The position slot switch 212 and the position sensor work together to confirm whether the traveling assembly 2 has reached its position. The limit switch 210 and the limit sensor work together to provide final electrical protection for the traveling assembly 2 and prevent the traveling assembly 2 from running out of control and crashing off the ground rail 6.

[0041] Both ends of the ground rail 6 are provided with end blocks 61, and buffers 62 are provided on the opposite inner sides of the end blocks 61.

[0042] The shuttle of this utility model is used to transport goods back and forth between the loading point and the unloading point. After the shuttle arrives at the loading point and stops, a forklift driven by a human will places the tooling frame and materials on the chain 11 of the high and low chain conveyor 1, and the guide frame 19 ensures that the goods are placed in the center on the high and low chain conveyor 1.

[0043] The high and low chain conveyor 1 starts running. The first motor 141 and the first drive shaft 142 cooperate to drive the chain 11 to move synchronously. After the goods move to the ground end block 3 position, the ground barcode scanner 4 scans the barcode of the goods tool rack to confirm the specifications and dimensions of the tool rack and provide feedback. Then the chain conveyor starts to reverse so that the geometric center of the goods coincides with the geometric center of the chain conveyor, and ensures that the geometric center of the goods is also the center position of the upper fork. This ensures that the goods are in the center of the fork when they are picked up, thus ensuring that the goods are in the center of the shelf when the stacker crane stacks them onto the shelf. The running distance of the goods on the chain 11 is precisely controlled by the encoder 15, and the reverse switch 17 confirms for the second time whether the geometric center of the goods coincides with the geometric center of the chain conveyor 1.

[0044] The blocking part 18 is used to ensure that the goods will not rush out of the high-low chain conveyor 1 in the event of an electrical failure when the high-low chain conveyor 1 is running in reverse. It is a mechanical protection device. The four weighing modules 16 at the bottom of the support column 13 will record the weight of the goods at all times and feed it back to the terminal.

[0045] In conventional chain conveyors, the chain section is located on a parallel plane. However, in this invention, the four-row chain 11 (high and low) is situated on two different planes. Two rows of chain 11 are on the lower plane, and two rows are on the higher plane. The two rows of chain 11 on the higher plane and the two rows on the lower plane maintain a fixed, non-adjustable height difference, ensuring overall stability. Furthermore, the four-row chain 11 utilizes a single drive unit. A first motor 141 transmits power stably to the four rows of high and low chains 11 through four sprockets and the chain, achieving complete synchronization. The cooperation of these components and the tooling frame is key to enabling the transport of goods of various sizes.

[0046] After the goods are placed, the second motor 203 starts to transmit power from the second drive shaft 204 to the walking wheels 205. The walking assembly 2 drives the high and low chain conveyor 1 and the goods on it to start moving. The weight of the goods is as high as 2 tons. Due to the weight and length of the goods, the maximum running distance of the entire shuttle is 10m. Therefore, for the sake of overall safety, the lateral movement speed of the shuttle cannot be too fast, and it starts and stops slowly. Therefore, when the shuttle is about to reach the stacker crane picking point, the deceleration slot-type switch 211 at the bottom of the shuttle walking frame 202 senses the deceleration sensor and decelerates. After decelerating for a certain distance, the positioning slot-type switch 212 at the bottom of the shuttle walking frame 202 touches the positioning sensor. The positioning slot-type switch 212 receives a signal, indicating that the goods have reached the stacker crane picking position and stopped. The stacker crane forks can then pick up the goods on the shuttle and complete the entire action process.

[0047] During operation, the traveling net bridge 201 on the shuttle and the ground net bridge 5 are aligned. The two net bridges sense each other, allowing for real-time and accurate feedback of the shuttle's position to the terminal. The entire system is powered by the sliding contact line 209. The ground rail 6 is a 38kg heavy rail, providing reliable support for the overall load. Horizontal guide wheels 206 are installed on the sides of the traveling wheels 205 to ensure straight-line movement. An end anti-collision device 207 is installed on the traveling frame 202, and an end stop 61 is installed at the end of the ground rail 6. A buffer 62 is installed on the end stop 61 to prevent the shuttle from running off the ground rail 6 in case of electrical failure; this serves as the final protection for the mechanical components. The buffer 62 is made of polyurethane.

[0048] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although this utility model has been described in detail with reference to examples, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
