Description

Stacking pallet splitting device, its splitting method and pallet conveying system

technical field

The invention relates to the field of conveying equipment, in particular to a stacking pallet dismantling device, a dismantling method thereof and a pallet conveying system.

Background technique

Pallets are horizontal platform devices used for assembly, stacking, handling and transportation of goods and products placed as unit loads. As a kind of loading equipment similar to containers, pallets have been widely used in production, transportation, warehousing and distribution and other fields.

As an important loading, unloading, storage and transportation equipment in the process of logistics operation, pallets play a huge role in modern logistics when used together with forklifts. The benefits it brings to the modern logistics industry are mainly reflected in: the unitization of item packaging can be realized , Standardization and standardization, protect items, facilitate logistics and business flow, pallets are also known as pallets.

In order to facilitate the use of pallets, in the existing conveying system, it is often necessary to disassemble the stacked pallets one by one and then transport them separately. Therefore, various pallet splitting equipment came into being, such as the patent application number 201821588441.8 The Chinese patent discloses a splitting device that lifts the top of the stacked pallets to a height close to that of the conveyor line through the lifting plate, and then pushes the top pallet to the conveyor line through the push plate on the side , although this splitting device effectively realizes splitting, there are still certain problems:

(1) When splitting, it is necessary to apply force to the pallet through the push plate to generate the power to move it. During the force application process, the push plate will receive a greater impact. Since the pallet is often a wooden structure, Therefore brought bigger damage to pallet.

(2) When the pallet receives lateral force and moves, it often drives the lower pallet to shift and shake, which affects the stability and position accuracy of the stacked pallet. Moreover, if the lower pallet tilts, it will Affect the stability of the subsequent push plate push.

(3) After the pallet moves to the conveying line, it needs to be limited by the baffle. The resistance of the baffle will easily cause damage to the pallet. On the other hand, the pallet will rebound and shift when it receives the resistance of the baffle , which leads to inconsistent positions of the pallets on the roller conveyor belt, which brings troubles to the subsequent automatic feeding.

(4) In the structure of this scheme, after a pair of stacked pallets are disassembled, another stacked pallet must be loaded, which causes time loss and is not conducive to the improvement of disassembly efficiency.

As shown in Figure 6, the support mechanism 3 includes at least four L-shaped support rods 31 distributed in a rectangular shape, which are respectively located on both sides of the conveying line 1, and the main support rods 31 located on the same side of the conveying line 1 The area near the turning point of the rod 311 is pivotally connected to a mounting plate 32 fixed on the side frame of the support frame 22, the mounting plate 32 extends along the conveying direction parallel to the conveying line 1, and the supporting The tail end 312 of the rod 31 is pivotally connected to a transmission rod 33, the transmission rod 33 is parallel to the mounting plate 32, and one end of the transmission rod 33 is pivotally connected to the cylinder shaft of the driving cylinder 34, and the driving cylinder 34 The cylinder axis is parallel to the transmission rod 33.

The reason why this structure is adopted is that the power source of this structure is less than that of the following direct cylinder support method, and the pressure of stacking pallets is mainly applied on the mounting plate 32, which has a very strong effect on the cylinder shaft. Small, but when the following is directly supported by the cylinder shaft, the pressure of the stacked pallets is applied to the cylinder shaft, and the load on the cylinder shaft is large. Long-term use will cause the cylinder shaft to bend and affect the use of the cylinder.

When the cylinder shaft of the driving cylinder 34 is retracted, the main rod 311 of the support rod 31 extends to the bottom of the pallet on the conveying line 1; when the cylinder shaft of the driving cylinder 34 is stretched out, the The support rod 31 rotates around its pivot with the mounting plate 32 , and its main rod 311 moves out to the outside of the pallet on the conveying line 1 .

Of course, in other embodiments, the support mechanism 3 can also be of other structures, for example, it can include four cylinders arranged on both sides of the conveying line, and the cylinder shafts of the cylinders are located on the conveying line 1 when the cylinder shaft shrinks. Outside the stacking pallet, the cylinder shaft of the air cylinder extends into the bottom of the stacking pallet when extended, thereby providing support.

Further, in order to adapt to pallets of different heights, the support mechanism 3 is set on a lifting structure (not shown in the figure) that drives its lifting. The lifting structure can be an electric cylinder or an oil cylinder, etc., which are known here Technology, not to repeat.

In addition, in order to improve disassembly efficiency, when the lifting mechanism 2 and the support mechanism 3 are disassembled, another stack of pre-stacked pallets 20 to be disassembled can be placed above the conveying line 1, but since the conveying line is dismantling Time-sharing is in the working state. At this time, it is necessary to prevent the pre-stacking pallet 20 from moving with the conveying line 1. For example, the pre-stacking pallet 20 can be blocked by a stopper, but after blocking, there will be a gap between the conveying line and the bottom pallet. Maintaining a certain amount of friction will cause wear and tear on both the conveying line and the pallets, and may even cause the stacked pallets to tilt. Therefore, the method of suspending the pre-stacked pallets 20 above the conveying line 1 is used to realize timely feeding. Correspondingly, as shown in accompanying drawings 1 and 3, the hollow area 11 is also provided with a lifting device 4 located at the front end of the conveying line 1 (when the conveying line 1 is conveying, the first passing position is the front), The top surface 41 of the lifting device 4 can be switched between a fourth height and a fifth height, the fourth height is not higher than the conveying surface of the conveying line 1, and the fifth height is higher than the conveying surface. Conveying surface of line 1.

Further, in order to protect the stacked pallets located on the conveying line 1 and prevent the pallets that are too high from falling out of the conveying line 1, as shown in Figure 8, protective Blocking 5, the protective blocking 5 is a frame structure composed of criss-crossing circular tubes, and the openings at both ends of the protective blocking 5 on both sides are bell mouths, and in order to facilitate the application of pallets of different sizes, the protection on both sides The distance between the barriers 5 can be adjusted. Specifically, the protective barriers 5 are fixed on the tripods 8 located on both sides of the conveying line 1 through a set of screw rods 6 and nuts 7. By adjusting the screw rods 6 on the The installation position on the tripod 8 can adjust the distance between the protective barriers 5, and one side of the lifting device 4 does not have the protective barriers 5, thereby facilitating feeding.

Finally, when the entire stacking pallet splitting device is working, various known control devices (not shown in the figure), such as PLC, or a computer equipped with control software control the start and stop or work of each cylinder, motor, etc. State switching, and various sensors can be combined to send corresponding control command switching to various control devices, which is a known technology here and will not be described in detail here.

As shown in the accompanying drawing 13, in this preferred embodiment, in order to make the articles can be uniformly transferred from the fixed position of the second conveying line 92 to the first conveying line 91 and prevent the articles from being transported by the second conveying line 92 Sliding out, the end of the second conveying line 92 is fixed with a baffle 9203 for blocking the progress of the articles.

There are still many implementations in the present invention, and all technical solutions formed by equivalent transformation or equivalent transformation fall within the protection scope of the present invention.
