Description

Technical Field

[0001] The invention relates to the field of stackers, and in particular to an operating method of a stacker for automated warehousing. Background Art

[0002] The main purpose of the stacker is to shuttle back and forth in the aisles of high-rise shelves to store the goods at the entrance of the aisle into the cargo compartment; or, to take out the goods in the cargo compartment and transport them to the entrance of the aisle. In the process of storing or taking out the goods, the stacker needs to fork, lift, lower and quickly move the goods many times. During these processes, the stacker often causes the forked goods to tilt or shift during transportation due to the vibration generated by the equipment itself, or the inertia caused by lifting, lowering and transporting. This is not obvious when the weight of the goods is large. If the weight of the goods is less than a certain value, the displacement of goods or the tilt of goods due to displacement due to these reasons is becoming more and more common. The displacement or tilt of goods often causes various deviations in the storage position of the goods in the shelf, which greatly affects the next time the stacker takes out the goods from the shelf, and also causes great trouble for people to transport and take out the goods from the aisle entrance.

[0035] In this embodiment, the goods handling device 4 includes a goods support 41, a slide rail 42, and a slide rail motor 43. The goods support 41 is fixedly installed on the connecting column 33 on the side of the single column 3. The slide rail 42 is slidably installed above the goods support 41. The slide rail motor 43 is fixed on the goods support 41 and is located on the side of the slide rail 42. The slide rail motor 43 is connected to a gear shaft 44. The gear shaft 44 is rotatably connected to the goods support 41 and is provided with two gears 45 thereon. The gears 45 are engaged with a rack 46. The rack 46 is fixed below the slide rail 42. A goods anti-tilting device 5 is provided inside the slide rail 42. Driven by the slide rail motor 43, the gears 45 drive the rack 46 to move forward or backward, moving the goods 6 placed on the slide rail 42 forward and stacking them on the shelf or moving backward to carry them out from the shelf.

[0036] In this embodiment, the goods anti-tilting device 5 includes a friction pad 50, a push button switch 51, an electric push rod 52, a wedge-shaped extrusion block 53, a wedge-shaped rising block 54, and a roller plate 55. The friction pad 50 is fixed on the upper surface of the slide rail 42. The push button switch 51 is arranged at the middle position of the friction pad 50. The electric push rod 52 is electrically connected to the push button switch 51 and the output shaft of the electric push rod 52 is connected to the rear end of the wedge-shaped extrusion block 53. The wedging surface of the wedge-shaped extrusion block 53 is closely attached to the wedge-shaped rising block 54. The two side ends of the wedge-shaped rising block 54 are slidably installed in the slide rail 42 through guide blocks 56 integrally formed with the slide rail 42 and its upper surface is closely attached to the inner surface of the slide rail 42. The roller plate 55 is located above the wedge-shaped rising block 54. A plurality of rollers 57 are evenly arranged on the roller plate 55. After the goods 6 are placed on the slide rail 42, the goods 6 press down the push button switch 51, starting the electric push rod 52. The electric push rod 52 pushes the wedge-shaped extrusion block 53 to slightly lift the end of the slide rail 42, causing the slide rail 42 to drive the whole goods to incline inward, preventing the goods from vibrating and displacing. At the same time, the roller plate 55 will be lifted by the wedge-shaped rising block 54, causing the rollers 57 to contact the goods 6. The goods 6 are on the rollers 57 and the calibration wheels 59 and slide inward along the inclined slide rail 42 under the action of gravity, with one side tightly against the calibration block 58, effectively calibrating the inclination generated by the goods 6.

The limiting plate 84 is connected to the guide rail plate 84 through the guide rail 86 and is located behind the rear side of the fixing plate 82. The energy absorption spring 85 is fixed between the fixing plate 82 and the guide rail plate 83. When the goods 6 slide inward along the inclined slide rail 42, it can effectively absorb its kinetic energy and potential energy, preventing the goods 6 from suddenly stopping and slipping off the clamping plate 7 when being blocked by the alignment block 58 during sliding. Moreover, the energy absorption device 8 can also absorb the vibration of the equipment during the operation of the stacker, avoiding the impact of vibration on the goods.

[0039] Working principle: When handling the goods 6, first move the goods handling device 4 and the goods anti-tilting device 5 to the designated position through the traveling wheels 22. After moving the goods 6 onto the goods support 41, the goods 6 presses down the push button switch 51 to start the electric push rod 52. The electric push rod 52 pushes the wedge-shaped extrusion block 53 to slightly lift the end of the slide rail 42, causing the slide rail 42 to drive the whole goods to tilt inward, preventing the goods from generating vibration displacement. At the same time, the roller plate 55 will be lifted by the wedge-shaped rising block 54, making the rollers 57 contact the goods 6. The goods 6 are on the rollers 57 and the alignment wheels 59 and slide inward along the inclined slide rail 42 under the action of gravity, with one side tightly against the alignment block 58, effectively correcting the tilt generated by the goods 6. During the operation of the stacker and the handling process of the goods 6, the energy absorption spring 85 can effectively absorb the kinetic energy and potential energy of the goods 6 when they slide inward along the inclined slide rail 42, preventing the goods 6 from suddenly stopping and slipping off the clamping plate 7 when being blocked by the alignment block 58 during sliding. Moreover, the energy absorption device 8 can also absorb the vibration of the equipment during the operation of the stacker, avoiding the impact of vibration on the goods.

[0040] Based on the above, when handling goods, the pressing switch of the invention can be depressed by the gravity of the goods to start the electric push rod, which pushes the wedge-shaped extrusion block to slightly lift the end of the slide rail, causing the slide rail to drive the whole goods to incline inward, preventing the goods from vibrating and shifting; at the same time, the roller plate will be lifted by the wedge-shaped rising block, so that the rollers contact the goods, and under the action of the rollers and the calibration wheels, the goods slide inward along the inclined slide rail under the action of gravity, with one side tightly against the calibration block, effectively correcting the inclination of the goods; after the goods are placed on the shelf, the slide rail moves downward, the pressing switch is released, the roller plate no longer holds the goods, and the goods can be placed on the shelf in a standard form for the next retrieval; the energy absorption device can effectively absorb the kinetic energy and potential energy of the goods when they slide inward along the inclined slide rail, preventing the goods from suddenly stopping and slipping off the pallet when blocked by the calibration block, and the energy absorption device can also absorb the vibration of the equipment during the operation of the stacker, avoiding the impact of vibration on the goods.

[0041] As is known by technical common sense, the present invention can be implemented by other embodiments without departing from its spiritual essence or essential features. Therefore, the above-disclosed embodiments are illustrative in all aspects and not exclusive. All changes within the scope of the present invention or equivalent to the present invention are encompassed by the present invention.
