Description

Technical Field

[0001] The invention relates to the technical field of packaging box transportation and storage, and in particular to a storage and transportation box for a Tetra Brik packaging box and a storage method. Background Art

[0002] At present, when transporting Tetra Brik boxes, multiple boxes are generally stacked vertically to form a stack. However, with the growth of market demand, the height and number of packaging stacks continue to increase, and the stability defects of this traditional stacking method are becoming more and more prominent. Dynamic factors such as vehicle bumps during transportation can easily cause the stacking structure to become unstable, causing the boxes to shift or even tip over. In order to enhance stability, the existing technology mostly applies an extrusion force to the neatly stacked boxes from the outside to fix them.

[0003] However, from the perspective of mechanical principles and actual application scenarios, in order to ensure that the packaging box remains upright under complex transportation conditions, the external force required is often relatively large. When acting on the packaging box, this large external force can easily exceed the reasonable pressure range that the packaging box material can withstand, thereby causing the risk of the packaging being punctured. At the same time, excessive external pressure may also destroy the sealing integrity of the packaging, exposing the packaging box to the external environment and increasing the possibility of microbial contamination. Given that Tetra Brik packaging boxes are widely used in food, medicine and other product packaging fields that require a sterile environment, once the packaging is damaged, microbial invasion will be inevitable, seriously threatening the quality and safety of the product. Therefore, during the transportation of the packaging box, how to effectively coordinate the relationship between the force required to fix the packaging box and preventing the packaging box from being damaged due to excessive pressure has become a core issue that needs to be overcome in the field of packaging technology. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a storage method for a Tetra Pak packaging box, which effectively prevents the packaging box from being punctured or contaminated due to excessive squeezing during transportation, ensures a sterile environment inside the packaging box, and guarantees the transportation quality of large quantities of packaging boxes.

[0013] The present invention also provides a storage method of a storage and transportation box of a Tetra Brik packaging box, comprising the following contents: S1. Place a specified number of flat packaging boxes into the transport box. After the second pressure sensing module detects the pressure signal, the second air inlet valve opens, and the air pressure supply mechanism starts to supply airflow to the second air cavity until the first pressure sensing module detects that the pressure parameter reaches the system preset conventional clamping reference value Pc. The second air inlet valve closes, and the system stores the pressure parameter currently detected by the second pressure sensing module as Pm.

[0014] S2. When the transport vehicle bumps, the flat packaging box shakes, and the first pressure sensing module detects the pressure parameter in real time. Suppose the real-time pressure parameter detected by the first pressure sensing module is Px, and the real-time pressure parameter detected by the second pressure sensing module is Py.

[0015] S3. When Px < Pc and Py > Pm, the first pressure difference ΔP1 = Pc - Px, and the second pressure difference ΔP2 = Py - Pm.

[0016] S3.1. The valve opening degree parameter value F(λ 11 ) ∝ the parameter value F(ΔP1) of the first pressure difference.

[0025] S5. When Px = Pc and Py = Pm, and the duration reaches the preset delay reference duration Ts of the system, the first intake valve, the first exhaust valve, the second intake valve, and the second exhaust valve are all completely closed.

[0026] As a preferred technical solution of the storage method of the present invention: the valve opening degree parameter values ​​of the first air inlet valve, the first air outlet valve, the second air inlet valve, and the second air outlet valve are ∈[0,1]. When the valve opening degree parameter value = 0, the valve is completely closed. When the valve opening degree parameter value = 1, the valve is completely open.

[0027] The present invention provides a storage and transportation box and a storage method for a Tetra Brik packaging box, which have the following beneficial effects: 1. In the present invention, the stacked flat packaging boxes are clamped up and down by the first clamping assembly and the second clamping assembly inside the transport box, which can effectively prevent the packaging boxes from shifting or tipping over due to bumps during transportation, thereby ensuring transportation stability. In addition, the first air cavity in the first clamping assembly and the second air cavity in the second clamping assembly are respectively connected to corresponding pneumatic assemblies, and the pressure in the air cavity can be accurately adjusted through the coordinated work of the air inlet pipe, the air outlet pipe, the air inlet valve, and the air outlet valve, thereby achieving precise control of the clamping force of the packaging box.

[0028] 2. The pressure sensing modules respectively embedded on the bottom sides of the first and second displacement plates in the present invention can monitor the clamping pressure in real time, provide a basis for dynamic adjustment, ensure that the clamping force is always appropriate, and avoid damaging the packaging box due to excessive pressure or shaking the packaging box due to insufficient pressure. During transportation, when the vehicle bumps and causes the flat packaging box to shake, the pressure sensing module detects the pressure change, and the pneumatic component dynamically adjusts the valve opening degree according to the preset control logic to achieve real-time regulation of the air cavity pressure. For example, when the vehicle bumps and causes the pressure above to decrease and the pressure below to increase, the first air inlet valve increases the intake rate and the first air outlet valve reduces the exhaust rate. At the same time, the second air inlet valve reduces the intake rate and the second air outlet valve increases the exhaust rate, so that the clamping force automatically adapts to changes in road conditions and keeps the packaging box stable.

[0029] 3. In the present invention, when the transport vehicle is on a stable road section and the pressure remains stable for a preset period of time, each air inlet valve and air outlet valve are completely closed to reduce the air source power consumption of the air pressure supply mechanism and save energy. At the same time, unnecessary gas flow and valve movement are reduced, equipment wear is reduced, and the service life of the equipment is extended. In addition, damping elements are configured in the first air cavity and the second air cavity, which are connected to the displacement plate, and play a buffering role when the air cavity pressure changes, avoiding violent movement of the displacement plate due to sudden pressure changes, further stabilizing the clamping of the packaging box, and reducing the risk of damage to the packaging box due to impact.

[0030] 4. The present invention adopts precise pressure control and a stable clamping method, which effectively avoids internal contamination or puncture of the packaging box due to excessive squeezing during transportation, ensures the sterile environment inside the packaging box, and guarantees the transportation quality of large quantities of packaging boxes.

DETAILED DESCRIPTION

[0034] The following will be combined with the present invention Figure 1 , Figure 2 As well as the embodiments, the technical solution of the present invention is described more clearly and completely.

[0035] Embodiment 1: The present invention designs a storage and transportation box for a Tetra Brik packaging box, which mainly includes the following contents: Overall structure: The transport box 1 has an inner cavity area 2 for placing stacked flat packaging boxes 3.

The first air inlet pipe 401 and the second air inlet pipe 501 are independently connected to an air pressure supply mechanism 9 upstream, and the exhaust port at the end of the first air outlet pipe 402 is an open structure.

[0037] The second pneumatic assembly 5 includes a second air inlet pipe 501 and a second air outlet pipe 502 connected to the second air cavity 702. The second air inlet pipe 501 is provided with a second air inlet valve 504, the second air outlet pipe 502 is provided with a second air outlet valve 503, and the exhaust port at the end of the second air outlet pipe 502 is an open structure.

[0038] First clamping assembly 6: The first protective shell 601 is fixedly mounted on the top of the inner cavity area 2, and the opening of the first protective shell 601 faces downward. The first air cavity 602 is located inside the first protective shell 601, and the first displacement plate 603 is slidably mounted inside the first protective shell 601. The first piston ring structure 604 that is in sliding contact with the inner wall of the ring plate of the first protective shell 601 is configured on the ring side of the first displacement plate 603. The first pressure sensing module 605 is embedded on the bottom side of the first displacement plate 603, and a damping member 8 is configured in the first air cavity 602, and the damping member 8 is connected to the first displacement plate 603.

[0039] Second clamping assembly 7: The second protective shell 701 is fixedly mounted at the bottom of the inner cavity area 2, and the opening of the second protective shell 701 faces upward. The second air cavity 702 is located in the inner periphery of the second protective shell 701, and the second displacement plate 703 is slidably mounted in the second protective shell 701. The second piston ring structure 704 that is in sliding contact with the inner wall of the ring plate of the second protective shell 701 is configured on the ring side of the second displacement plate 703. The second pressure sensing module 705 is embedded on the bottom side of the second displacement plate 703, and a damping member 8 is configured in the second air cavity 702, and the damping member 8 is connected to the second displacement plate 703.

[0040] Embodiment 2: In the present invention, a storage method of a storage and transportation box of a Tetra Brik packaging box, the specific control method is as follows: First, initial placement and pressure testing: A specified number of flat packaging boxes 3 are placed in the transport box 1. After the second pressure sensing module 705 detects the pressure signal, the second air inlet valve 504 opens, and the air pressure supply mechanism 9 starts to supply air flow to the second air cavity 702 until the first pressure sensing module 605 detects that the pressure parameter reaches the system preset conventional clamping reference value Pc. The second air inlet valve 504 is closed, and the system stores the pressure parameter currently detected by the second pressure sensing module 705 as Pm.

[0041] Second, pressure monitoring and adjustment during transportation: When the transport vehicle bumps, the flat packaging box 3 shakes, and the first pressure sensing module 605 detects a real-time pressure parameter set to Px, and the second pressure sensing module 705 detects a real-time pressure parameter set to Py.

[0042] Case 1: When Px<Pc,Py> Pm, the clamping degree of the first displacement plate 603 on the flat packaging box 3 is weakened, and the clamping degree of the second displacement plate 703 on the flat packaging box 3 is increased, then the first pressure difference ΔP1=Pc-Px, and the second pressure difference ΔP2=Py-Pm.

[0043] At this time, the valve opening degree parameter value F (λ 11)∝ The parameter value F(ΔP1) of the first pressure difference (i.e., the gas replenishment rate of the first intake pipe 401 to the first air chamber 602 increases).

[0044] The valve opening degree parameter value F(λ of the first outlet valve 403 12 )∝ The parameter value F of the first pressure difference -1 (ΔP1)(The gas discharge rate of the first outlet pipe 402 to the first air chamber 602 decreases. In the present invention, the method of charging while discharging is designed to adjust the air pressure of the first air chamber 602 because when the air pressure in the first air chamber 602 is too high, restarting the first outlet valve 403 and correspondingly adjusting the valve opening degree of the first outlet valve 403 will result in a large system control and mechanical action delay. On the contrary, restarting the first intake valve 404 will also have a delay, resulting in an inappropriate clamping force of the first displacement plate 603 on the flat packaging box 3, causing the flat packaging box 3 to shake excessively or be clamped excessively. The control methods of the second intake valve 504 and the second outlet valve 503 are the same. For dynamic control, they are generally not completely closed to ensure the response speed of valve regulation).

[0045] The valve opening degree parameter value F(λ of the second intake valve 504 21 )∝ The parameter value F of the second pressure difference -1 (ΔP2)(The gas replenishment rate of the second intake pipe to the second air chamber 702 decreases).

[0046] The valve opening degree parameter value F(λ of the second outlet valve 503 22 )∝ The parameter value F(ΔP2) of the second pressure difference (The gas discharge rate of the second outlet pipe 502 to the second air chamber 702 increases).

[0047] Case 2: When Px > Pc and Py < Pm, the clamping degree of the first displacement plate 603 on the flat packaging box 3 increases, and the clamping degree of the second displacement plate 703 on the flat packaging box 3 attenuates. Then the third pressure difference ΔP3 = Px - Pc, and the fourth pressure difference ΔP4 = Pm - Py.

[0048] At this time, the valve opening degree parameter value F(λ of the first intake valve 404 11 )∝ The parameter value F of the third pressure difference -1 (ΔP3).

[0049] The valve opening degree parameter value F(λ of the first outlet valve 403 12 )∝ The parameter value F(ΔP3) of the third pressure difference.

[0050] The valve opening degree parameter value F(λ of the second intake valve 504 21 )∝ The parameter value F(ΔP4) of the fourth pressure difference.

[0051] The valve opening degree parameter value F (λ 22 )∝the parameter value of the fourth pressure difference F -1 (ΔP4).

[0052] Third, the treatment of stable road sections: When Px=Pc and Py=Pm, and the duration reaches the system preset delay reference duration Ts, the first air inlet valve 404, the first air outlet valve 403, the second air inlet valve 504, and the second air outlet valve 503 are all completely closed (indicating that the transport vehicle is on a relatively stable road section, closing the valves reduces the air source power consumption of the air pressure supply mechanism 9).

[0053] Finally, in the above content, the valve opening degree parameter values ​​of the first air inlet valve 404, the first air outlet valve 403, the second air inlet valve 504, and the second air outlet valve 503 are ∈[0,1], wherein when the valve opening degree parameter value = 0, the valve is completely closed; when the valve opening degree parameter value = 1, the valve is completely open.

[0054] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
