Description

Technical Field

[0001] The utility model relates to the technical field of shuttle vehicles, in particular to a four-way shuttle vehicle and a coil warehouse logistics system. Background Art

[0002] With the continuous development of science and technology, a large number of intelligent handling equipment are used in logistics warehousing, among which the four-way shuttle is favored by most people and is studied intensively. The four-way shuttle is flat as a whole, with two sets of mutually perpendicular wheels installed on two opposite sides, which can allow the shuttle to travel in four directions: front, back, left, and right. The body of the shuttle is equipped with a reversing mechanism and a jacking mechanism. Steering can change the height of one set of wheels to change the direction of travel of the shuttle. The jacking mechanism uses hydraulic cylinders, screw lifts and other equipment to control the height of the rod or plate to lift the goods.

[0003] Existing four-way shuttles are usually equipped with pallets. The pallets, goods, and shuttle passages form a storage unit. The existing storage units are relatively high due to the preset pallet space, which will lead to a reduction in the capacity of the entire three-dimensional warehouse. If the pallets are removed and only the shuttle's support rods and pallets are used to directly lift the goods, another difficulty will arise. Due to the requirement for the shuttle to be lightweight, the shuttle is relatively thin, and the hydraulic cylinder or screw lift it carries is affected by the thickness of the shuttle and has a very short stroke, which cannot meet the needs of cargo handling. Utility Model Content

[0004] Therefore, in order to solve the above-mentioned problems, the purpose of the utility model is to provide a four-way shuttle vehicle, including a vehicle body, in which a driving mechanism, a reversing mechanism and a lifting mechanism are arranged, the lifting mechanism includes a lifting motor and a lifting rod, the output end of the lifting motor is connected to a turntable, the rotating axis of the turntable is parallel to the ground, and a boss is connected to the side of the turntable away from the output end of the lifting motor, the boss rises / falls with the rotation of the turntable, and the lifting rod is connected to the boss.

[0005] Preferably, the lifting mechanism further comprises a movable plate, the upper end of which is fixedly connected to the lifting rod, and the movable plate is provided with a movable groove for accommodating the boss, and the boss can rotate or translate relative to the movable groove.

[0006] Preferably, the boss is cylindrical, the movable groove is arranged horizontally, a guide column is connected to the vehicle body, the lifting rod is fixedly connected to a guide block, and the guide block is clamped on the guide column.

[0008] Preferably, the two jacking mechanisms are symmetrically arranged in the vehicle body.

[0009] Preferably, the driving mechanism includes a first direction driving wheel group, a second direction driving wheel group and a driving motor, the driving motor is used to control the synchronous rotation of the wheels in the first direction driving wheel group and the second direction driving wheel group, the reversing mechanism includes a reversing motor, the output end of the reversing motor is connected to a cam, the cam is in contact with the second direction driving wheel group, and when the cam rotates, it can squeeze the second direction driving wheel group to make it rise / fall.

[0010] A coil warehouse logistics system includes a shelf and the above-mentioned four-way shuttle vehicle, with two jacking rods arranged in parallel and at the same height. The shelf includes a driving channel for the shuttle vehicle to pass through, and a coil support is symmetrically arranged above the driving channel. The coil support includes two parallel and equal-height rack rods.

[0011] The beneficial effects of the utility model are:

[0012] A horizontal lifting motor is used to control the rotation of the turntable. A boss is installed on the turntable. When the turntable rotates, the high end of the boss changes.

[0026] Embodiment 1:

[0027] Figure 1-Figure 5A four-way shuttle vehicle provided by the utility model is shown, including a vehicle body 1, which is flat as a whole. A driving mechanism 2 and a reversing mechanism 3, which are necessary for a shuttle vehicle, are arranged in the vehicle body 1, wherein the driving mechanism 2 includes a first direction driving wheel group and a second direction driving wheel group, and also includes a driving motor, which can drive the vehicle body 1 to move in the front, back, left and right directions respectively. A lifting mechanism 4 is also arranged in the vehicle body 1, and the lifting mechanism 4 includes a lifting motor 5 and a lifting rod 8. The output end of the lifting motor 5 is connected to a turntable 6, and the rotating axis of the turntable 6 is parallel to the ground. A boss 61 is connected to the side of the turntable 6 away from the output end of the lifting motor 5, and the boss 61 is eccentrically arranged relative to the rotating axis of the turntable 6, so when the turntable 6 rotates, the height of the boss 61 will change accordingly, and the lifting rod 8 is connected to the boss 61, and the boss 61 drives the lifting rod 8 to move up and down, so as to achieve the purpose of lifting and supporting the goods.

[0028] The boss 61 is connected to the lifting rod 8 through the movable plate 7, and the upper end of the movable plate 7 is fixedly connected to the lifting rod 8. The movable plate 7 is provided with a through movable groove 71 that can accommodate the boss 61. The boss 61 is clamped in the movable groove 71 and can rotate or translate relative to the movable groove 71. The inner edge of the vehicle body 1 has a guide structure that can limit the movable plate 7 to only make up and down translation movements. When the boss 61 rotates with the turntable 6, it swings left and right in the movable groove 71, so that the movable plate 7 moves up and down with the boss 61, thereby driving the lifting rod 8 fixed on the movable plate 7.

[0029] The guide structure is specifically a vertically arranged guide column 11. In the present embodiment, a guide block 81 cooperating with the guide column 11 is arranged on the side of the lifting rod 8. When the guide block 81 is engaged with the guide column 11, the lifting rod 8 can be limited to only make up and down translational movements. Since the movable plate 7 is fixedly connected to the lifting rod 8, the movable plate 7 also only makes up and down translational movements. Based on this design, the shapes of the boss 61 and the movable groove 71 are limited. The boss 61 is cylindrical, and the movable groove 71 is arranged in the horizontal direction. The boss 61 can translate left and right in the movable groove 71.

[0030] In the present embodiment, two turntables 6 are arranged, and the outer side surfaces of the turntables 6 have tooth patterns. The two turntables 6 can mesh with each other, and one of the turntables 6 is directly connected to the output end of the lifting motor 5. When the lifting motor 5 drives one of the turntables 6 to rotate, the other turntable 6 can be driven to rotate in the opposite direction at the same time through the meshing relationship. When the two turntables 6 rotate, the two bosses 61 always keep the same height. The movable plate 7 is correspondingly provided with two movable grooves 71 which respectively cooperate with the two bosses 61. The two bosses 61 provide symmetrical lifting forces to the movable plate 7 and the lifting rod 8. The lifting action of the lifting rod 8 is more stable and reliable. The two driving mechanisms 2 are symmetrically arranged in the vehicle body 1, and the goods rise more stably during lifting.

[0031] The reversing mechanism 3 includes a reversing motor and a cam 31 controlled by the reversing motor. The cam 31 is in contact with the second direction driving wheel set. When the reversing motor controls the cam 31 to rotate, the second direction driving wheel set is squeezed by the cam 31 and can move up and down. When the second direction driving wheel set drops to the lowest point, the height of the wheels therein is lower than the height of the wheels of the first direction driving wheel set. Therefore, at this time, the second direction driving wheel set is directly in contact with the ground or the laid track, and the shuttle can move in the second direction; conversely, when the second direction driving wheel set rises to the highest point, the first direction driving wheel set is directly in contact with the ground or the laid track. At this time, the second direction driving wheel set is suspended on the outside of the vehicle body 1, and the shuttle can move in the first direction.

[0032] The existing cam 31 is generally symmetrical in shape, such as Figure 4 This type of cam has high requirements on the torque provided by the commutation motor 3. After aging, the torque provided by the commutation motor 3 is unstable and may not be able to provide sufficient torque. Therefore, the cam shape is optimized to a certain extent. Figure 5 In this embodiment, the cam 31 is designed to be spiral. The spiral cam 31 prolongs the rotation amount during steering, but reduces the torque requirement, thereby preventing the reversing motor 3 from providing a low torque value due to aging or failure, which makes the reversing action fail.

[0033] The four-way shuttle vehicles on the market are usually equipped with eight sets of four wheels in a single direction, of which only four wheels are drive wheels. In this embodiment, all the wheels of the four-way shuttle vehicle are meshed and connected through a gear set, so all the wheels are drive wheels, and the driving force is stronger. The wheels will not slip with the running track, and the shuttle vehicle responds faster when accelerating and decelerating.

[0034] Working principle:

[0035] A horizontal motor is used to control the rotation of the turntable 6 with the boss 61, and the lifting rod 8 moves up and down accordingly. In the vehicle body 1 of the same thickness, the up and down stroke of the boss 61 on the turntable 6 is greater than the up and down stroke of the hydraulic cylinder and the screw lift. The up and down stroke of the lifting rod 8 is increased within the range of the same size specification. When transporting goods, the original pallet can be eliminated and the height of the single shelf 9 can be reduced, so that the three-dimensional warehouse can accommodate more goods.

[0036] Embodiment 2:

[0037] Figure 6-Figure 7A coil warehouse logistics system provided by the present embodiment is shown, comprising the four-way shuttle vehicle in Embodiment 1 and a shelf 9 arranged in the warehouse. The present embodiment is mainly used for the transportation of coils, so the lifting rods 8 are further restricted: a set of lifting rods 8 has two and are arranged in parallel at the same height, the coils can be clamped on the two sets of lifting rods 8 and will not roll off, the shelf 9 includes a driving channel for the shuttle vehicle to pass, and a coil support is symmetrically arranged above the driving channel, the coil support includes two parallel and equal-height racks 91, the racks 91 and the lifting rods 8 are staggered relative to the coils, and the racks 91 are located in the up and down travel of the lifting rods 8.

[0038] Coil handling process:

[0039] The lifting motor 5 controls the lifting rod 8 to rise and lift the coil. After the coil is placed stably, the shuttle car transports the coil to the designated shelf 9 through the driving mechanism 2 and the reversing mechanism 3. The lifting motor 5 controls the lifting rod 8 to descend. After the coil moves downward, it is lifted by the rack rod 91 and fixed on the shelf 9.

[0040] The design purpose of this embodiment is mainly to solve the problem of coil handling in the prior art. It is known that coils are easy to roll. If pallets are used for loading, a limit device needs to be installed, which is extremely inconvenient. If a double-rod lifting rod 8 is used, it can both lift the coil and limit the coil from rolling and falling off. However, this also brings a new problem, that is, the height of the lower end of the coil is lower than the height of the end point where the lifting rod 8 abuts against the coil. If the up and down stroke of the lifting rod 8 is not large enough, the lower end of the coil may abut against the shuttle car, and the coil rolls on the shuttle car. The lifting rod 8 can only play a role in limiting the rolling of the coil within a certain range. If the coil is heavy and has a large inertia, there is still a risk of rolling off. In addition, the body 1 of the shuttle car was originally designed not to carry goods. Overweight coils may bend the upper cover of the body 1. The above problem can be solved in the application embodiment 1 by using a shuttle car with a larger stroke and then cooperating with the shelf 9 of this embodiment.

[0041] The present embodiment is applicable to the loom shafts in the denim industry, specifically, the intermediate raw materials in the production process of denim (textile industry), the warp threads are wound around a loom shaft, and there are many sizes and styles of loom shafts during the production process. Usually, the shaft length of the loom shaft ranges from 1800 to 2600 mm, and the flange spacing ranges from 1600 to 2500 mm. Conventional simple shelves cannot be compatible with loom shafts of various sizes. The four-way shuttle and shelf provided in the present embodiment can meet the storage needs of loom shafts of various sizes and styles.

[0042] The above description is only an optional embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
