At the same time, multiple sets of telescopic rods are installed in the car, which can make it more convenient to load cargo. The overall use is more convenient, and it can carry a larger weight, which is conducive to the transportation of large cargo.

[0004] However, in the more commonly used logistics field, during the actual stacking and handling process, we often encounter some packaging surfaces that are very rough, such as packaging boxes made of cardboard. The distance that this type of packaging box can be pushed by the electric push rod on the loading platform is very short, and it is difficult to quickly reach the designated stacking point in a short time. This loading and unloading method is not only time-consuming, but also causes the goods to shift, resulting in skewed stacking, posing a safety hazard.

[0005] Therefore, a high-speed stacker with an automated stacking function is proposed to solve the above-mentioned problems. Summary of the invention

[0006] Technical issues solved In view of the above-mentioned shortcomings of the prior art, the present invention provides a high-speed stacker with an automated stacking function, which can effectively solve the problem of low loading and unloading efficiency of the stacker in the prior art.

In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0026] The present invention will be further described below in conjunction with the embodiments.

[0027] Example

[0028] See attached Figure 1-8 This case proposes a high-speed stacker with automatic stacking function, including a door-shaped bracket 1 and a shelf board 2. The door-shaped bracket 1 is composed of two columns and two Q235 steel columns (height 5m, spacing 2m) and a beam located between the two columns. The surface of the column is installed with a guide rail, and the beam is integrated with a chain lifting mechanism driven by a servo motor.

[0029] A group of winding rollers 11 are fixedly installed on the side of one of the pillars. Four cables are covered on the winding rollers 11. The cables are hung on the shelf board 2 through a pulley set. Two cables are respectively arranged on both sides of the length direction of the shelf board 2 for suspension. This is a well-known technology and will not be elaborated here.

[0030] The shelf plate 2 is connected to the door-shaped bracket 1 through a chain and can be vertically lifted and lowered along the column at a lifting speed of 1.5m / s; the storage platform 21 of the shelf plate 2 is an aluminum alloy plate (1.8m long and 1.2m wide).

[0031] Thus, by winding and loosening the cable, the shelf board 2 can be movably mounted on the door-shaped bracket 1 and can be reciprocated and lifted along the height direction of the door-shaped bracket 1.

[0032] When in use, first lift the shelf board 2 downward, place the goods to be stacked on the shelf board 2 manually or by a robot, start the motor, let the shelf board 2 rise to the required stacking height, and then send the goods on the shelf board 2 to the designated stacking point.

[0033] It should be noted that the shelf board 2 in this embodiment includes a storage platform 21 for placing goods, and a push plate 22 and a lifting plate 23 are movably installed on the rear side and the bottom end of the storage platform 21 respectively. The push plate 22 can move from the back to the front, and while the goods on the storage platform 21 are pushed by the push plate 22, the lifting plate 23 rises along the height direction of the shelf board 2 and lifts the goods, and a plurality of rotating rollers 231 are arranged on the lifting plate 23.

[0034] In this embodiment, a plurality of slots 211 for extending the rotating roller 231 are arranged along the width direction of the storage platform 21. Each slot 211 is opened along the length direction of the storage platform 21. The size of the slot 211 is not specifically limited. In this embodiment, the slot width of the slot 211 is 20 mm and the spacing is 200 mm.

[0035] In this embodiment, the push plate 22 is tilted at an angle of 15° and is driven by a cylinder or a telescopic push rod to move horizontally.

[0036] It is worth mentioning that in the present embodiment, the height of the upper plane of the storage platform 21 is lower than the lower plane of the push plate 22, so that when placing goods, the bottom surface of the goods will contact the upper plane of the storage platform 21, but because the height of the upper plane of the storage platform 21 is lower than the lower plane of the push plate 22, the rear bottom end of the goods intersects with the push plate 22, thereby limiting the displacement of the goods.

[0037] At the same time, a limiting structure is also provided at the front end of the goods. A baffle plate 212 is also hinged at the front end of the storage platform 21. The lower end plane of the storage platform 21 is not higher than the lower end surface of the hinge shaft on the baffle plate 212. When the goods are placed normally, that is, when the storage platform 21 is rising, since the lower end plane of the storage platform 21 is not higher than the lower end surface of the hinge shaft on the baffle plate 212, that is, it is at most flush with the cross-section of the hinge shaft on the baffle plate 212, when the goods are placed on the storage platform 21, the bottom end of the goods contacts the hinge shaft of the baffle plate 212, and the baffle plate 212 cannot rotate at this time, thereby ensuring that the goods will not tilt forward.

[0038] Furthermore, when the lifting plate 23 rises to the maximum height, the top cut surface of the rotating roller 231 intersects with the upper end surface of the hinge shaft on the baffle 212. When it reaches the specified position, as the lifting plate 23 rises, it will drag the goods up, and the front end of the goods will gradually move away from the hinge shaft of the baffle 212 and move toward the upper part of the baffle 212. In addition, as the pushing plate 22 is pushed and the rotating roller 231 rotates, the goods will gradually pass over the lifting plate 23, and the lifting plate 23 will be "pressed" by the rear side of the goods to rotate to form a downward slope to facilitate the detachment of the goods.

[0039] Compared with the traditional technology of directly using a linearly moving push rod, this solution makes it easier to load and unload goods with greater friction.

[0040] It should be noted that, in order to avoid movement obstruction of the push plate 22 , the top end section of the rotating roller 231 is always lower than the lower end plane of the push plate 22 .

[0041] In the present case, the coordinated actions of the push plate 22 and the lifting plate 23 are not specifically limited. In the present embodiment, a roller 221 (with a diameter of 50 mm and made of nylon) is welded on both sides of the push plate 22. A rolling groove 232 for the roller 221 to roll therein is provided at the side end of the lifting plate 23. The roller 221 is embedded in the rolling groove 232 of the lifting plate 23, and the rolling groove 232 is tilted forward and downward for a distance from the rear end face of the push plate 22 and then extends horizontally forward.

[0042] It should be noted that when the roller 221 has not yet rolled in the rolling groove 232, the roller 221 will be located at the initial position of the rolling groove 232, and the notch of the rolling groove 232 will be rounded to allow the roller 221 to roll smoothly into the rolling groove 232. Since the internal slope of the rolling groove 232 changes, the lifting plate 23 will begin to rise as the roller 221 moves.

[0043] The lifting plate 23 is integrated with a motor and a plurality of rotating rollers 231 driven by the motor.

[0044] In terms of safety, two situations are also taken into consideration in this embodiment. First, some cargoes are heavy. Therefore, when the cargoes are in the process of leaving the storage platform 21 , the movement of the push plate 22 will reinforce the current storage platform 21 .

[0045] Specifically, a plurality of horizontal columns 10 are arranged at intervals along the height direction of the column, and each horizontal column 10 is provided with a positioning groove 101. A positioning block 222 is connected to the side end of the push plate 22, and the positioning groove 101 is located on the moving path of the positioning block 222. When the push plate 22 starts to move and pushes the goods forward, the positioning block 222 will be stuck in the positioning groove 101 to be locked.

[0046] It is worth noting that when the positioning block 222 and the positioning groove 101 are matched, the matching point is located in the middle of the entire storage platform 21.

[0047] In addition, during the operation of a stacker that uses wire rope lifting, the wire rope may deviate from the preset winding roller groove, causing the wire rope to become tangled and the length and tension on both sides to be inconsistent, affecting safe operation.

[0048] And the cable in the present embodiment is normally arranged in the winding roller rope groove in sequence.If abnormal situation occurs, the steel wire rope must have at least one section to cross the rope groove edge, causing protrusion.

[0049] A touch sensor 12 is arranged directly below the winding roller. When the wire rope is entangled or misplaced and presses and triggers the sensor 12 below, the sensor 12 moves downward. A reset spring 121 is arranged at the bottom. The sensor 12 transmits the signal to the PLC. The PLC is connected to the motor that controls the rotation of the winding roller. It can be determined that the wire rope has deviated from the rope groove, the equipment stops, the winding roller stops rotating and an alarm is sounded, prompting the staff to carry out maintenance.

[0050] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
