Description

Technical Field

[0001] This utility model relates to the field of food disinfection technology, and in particular to a height control device for a food disinfection transfer vehicle. Background Technology

[0002] Foods such as turtle jelly are often packaged in plastic bowls. To ensure food safety, the plastic bowls containing the turtle jelly need to be sterilized in sterilizers before leaving the factory. To improve sterilization efficiency, the plastic bowls need to be collected in a sterilization transport cart before being conveyed to the sterilizer for high-temperature sterilization. Currently, the sterilization transport carts are multi-layered, and workers need to adjust the height of the cart using a lifting platform before pushing the plastic bowls into it. The current lifting platform is manually controlled, and the height difference between the buffer platform and the sterilization transport cart needs to be less than 1 cm when the plastic bowls are pushed from the buffer platform to the cart. The manual adjustment of the lifting platform is slow, reducing work efficiency. Therefore, a height control device for food sterilization transport carts needs to be designed, which can automatically adjust the height of the sterilization transport cart using a through-beam photoelectric switch, shortening the time spent adjusting the height of the cart and improving work efficiency. Utility Model Content

[0003] To address the aforementioned issues, this invention proposes a height control device for a food disinfection transfer cart. This device utilizes a through-beam photoelectric switch to automatically adjust the height of the disinfection transfer cart, thereby reducing the time required for the lifting platform to adjust the cart's height and improving work efficiency.

[0004] This utility model is achieved through the following technical solution:

[0005] This utility model proposes a height control device for a food disinfection transfer vehicle, comprising: a disinfection transfer vehicle, a lifting mechanism, and a through-beam photoelectric switch. The lifting mechanism is installed in a pit in the ground, and a lifting platform is provided on the upper part of the lifting mechanism. The disinfection transfer vehicle is parked on the lifting platform. The disinfection transfer vehicle includes a frame and support plates. Multiple support plates are installed in the frame in a vertical direction, and a light shield is provided on one side of each support plate. The through-beam photoelectric switch is installed on both sides of the lifting platform through a support frame, and the light emitted by the through-beam photoelectric switch can be blocked by the light shield.

[0006] Furthermore, the uprights of the frame are provided with support blocks, the four corners of the support plate are mounted on the frame through the support blocks, and the light shields on all the support plates are located on the same vertical line, and the light emitted by the through-beam photoelectric switch is perpendicular to the vertical line.

[0007] Furthermore, the support plate is provided with multiple dividing strips, which divide the support plate into multiple placement slots.

[0008] Furthermore, the frame is provided with a slot, and the slot is provided with a baffle, which blocks one side of the placement slot.

[0009] Furthermore, the lifting platform is provided with a limiting groove, and the lower part of the disinfection transfer vehicle is provided with rollers, and the disinfection transfer vehicle is parked in the limiting groove by the rollers.

[0010] Furthermore, a pin hole is provided on one side of the limiting groove, and a pin is provided in the pin hole, which blocks the roller on one side.

[0011] Furthermore, the lifting mechanism is a scissor lifting mechanism, and a hydraulic rod is provided in the lifting mechanism.

[0012] Furthermore, the height of the light-shielding plate is 5cm to 10cm.

[0013] The beneficial effects of this utility model are as follows: When the lifting mechanism adjusts its height, a light shield is used to block the light emitted by the through-beam photoelectric switch, and a PLC controller is used to control the lifting mechanism, so that the lifting mechanism can automatically adjust the height of the disinfection transport vehicle, shortening the time consumed by the lifting platform to adjust the height of the disinfection transport vehicle and improving work efficiency.

Detailed Implementation

[0018] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Throughout the description, the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0019] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0020] Furthermore, the use of terms such as "first" and "second" in this utility model is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined with "first" and "second" may explicitly or implicitly include at least one of the stated features. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. If the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0021] like Figure 1 , Figure 2 , Figure 3 As shown, an embodiment of this utility model provides a height control device for a food disinfection transfer vehicle, including: a disinfection transfer vehicle 1, a lifting mechanism 2, and a through-beam photoelectric switch 3. The lifting mechanism 2 is installed in an equipment pit on the ground, and a lifting platform 4 is provided on the upper part of the lifting mechanism 2. The disinfection transfer vehicle 1 is parked on the lifting platform 4. The disinfection transfer vehicle 1 includes a frame 5 and a support plate 6. Multiple support plates 6 are installed in the frame 5 in a vertical direction, and a light shield 7 is provided on one side of the support plate 6. The through-beam photoelectric switch 3 is installed on both sides of the lifting platform 4 through the support frame, and the light emitted by the through-beam photoelectric switch 3 can be blocked by the light shield 7.

[0022] When food products such as turtle jelly are packaged in plastic bowls, the bowls are filled, sealed, and covered before being conveyed onto a buffer platform. When the lifting mechanism 2 is at its lowest point, the lifting platform 4 is flush with the ground. The disinfection transport cart 1 is placed on the lifting platform 4. At this time, the uppermost support plate 6 of the disinfection transport cart 1 is flush with the buffer platform or 2mm to 5mm lower. The upper surfaces of the buffer platform and support plate 6 are smooth. Workers push the plastic bowl packaging from the buffer platform into the placement slots of the support plate 6. After one layer of support plates 6 is filled, the worker presses the switch to raise the lifting mechanism 2, causing the lifting platform 4 and the disinfection transport cart 1 to rise. Initially, the lifting platform 4 rises at a speed of 4cm / s. When the light shield 7 blocks the light from the through-beam photoelectric switch 3, the lifting platform... The lifting speed of platform 4 is adjusted to 1-2 cm / s. As the height increases, the through-beam photoelectric switch 3 passes through the lower space of the support plate 6. When the receiver of the through-beam photoelectric switch 3 receives the through-beam light again, the lifting platform 4 stops lifting. At this position, the support plate 6 of the next layer stops exactly 2mm to 5mm lower than the buffer platform. The worker continues to push the plastic bowl packaging from the buffer platform into the placement slot of the support plate 6. By repeating the above operation, after the entire disinfection transfer cart 1 is filled, the lifting platform 4 is controlled to descend, and then the disinfection transfer cart 1 is pushed onto the conveyor belt. The disinfection transfer cart 1 is sent into the sterilization cabinet by the conveyor belt. It is disinfected by high temperature, ozone and other methods. After the plastic bowl packaging is disinfected, it is finally sealed and packaged.

[0023] The height of the through-beam photoelectric switch 3 is equal to the height of the buffer platform - the thickness of the support plate 6 - the redundancy dimension, where the redundancy dimension is 1mm to 3mm. When the lifting platform 4 rises, the signal state of the through-beam photoelectric switch 3 is: ① sensing → ② blocking → ③ sensing. In stage ①, the light emitted by the through-beam photoelectric switch 3 passes through the lower part of the upper support plate 6, which is the sensing state. The PLC controller is programmed to obtain the signal of the through-beam photoelectric switch 3 and control the lifting platform 4 to perform corresponding actions. In stage ②, the speed is reduced to 1-2cm / s. As the lifting platform 4 continues to rise, the light emitted by the through-beam photoelectric switch 3 will pass through the lower part of the upper support plate 6 again. The lower part passes through, at which point the PLC controller will stop the lifting platform 4 from rising. Since the speed of the lifting platform 4 has already decreased in stage ②, it can be stopped quickly when entering stage ③, ensuring that the support plate 6 is stopped at a position 2mm to 5mm lower than the buffer platform. For disinfection transfer carts 1 produced in different batches, the interval of each support plate 6 is different. Therefore, the solution of the light shield in this application can be compatible with disinfection transfer carts 1 with different height intervals. The worker can automatically control it after pressing the lifting button. The stopping position of the lifting platform 4 is controlled by the through-beam photoelectric switch 3, which greatly reduces the time required to adjust the height of the lifting platform 4 and improves the loading efficiency of the disinfection transfer cart 1.

[0024] Preferably, the uprights of the frame 5 are provided with support blocks 8, and the four corners of the support plate 6 are installed on the frame 5 through the support blocks 8. The support blocks 8 support the support plate 6 to ensure that the support plate 6 is in a stable state. The light shields 7 on all the support plates 6 are located on the same vertical line. The light emitted by the through-beam photoelectric switch 3 is perpendicular to the vertical line. When the lifting platform 4 is raised, the light shields 7 can block the light emitted by the through-beam photoelectric switch 3 in turn, so as to control the raising and stopping of the lifting platform 4 through the feedback signal of the through-beam photoelectric switch 3.

[0025] Specifically, such as Figure 2 As shown, the support plate 6 is provided with multiple dividing strips 9, and the support plate 6 is divided into multiple placement slots by the dividing strips 9, so that the plastic bowl packaging can be neatly arranged on the support plate 6, and the plastic bowl packaging can be heated evenly when sterilized in the sterilizer.

[0026] Specifically, the frame 5 is provided with a slot, and a baffle 10 is provided on the slot, which blocks one side of the placement slot. After each layer of support plate 6 is filled, the baffle 10 blocks one side of the placement slot to prevent the plastic bowl packaging from sliding out of the placement slot.

[0027] In a preferred embodiment, the lifting platform 4 is provided with a limiting groove 11, and the lower part of the disinfection transfer cart 1 is provided with rollers 12. The disinfection transfer cart 1 is positioned in the limiting groove 11 by means of the rollers 12. This allows the disinfection transfer cart 1 to stop accurately on the lifting platform 4, and when transferring the plastic bowl packaging, it allows the plastic bowl packaging to be transferred more smoothly from the buffer platform to the support plate 6.

[0028] In a preferred embodiment, a pin hole is provided on one side of the limiting groove 11, and a pin 13 is provided in the pin hole, which blocks one side of the roller 12. By blocking the roller 12 with the pin 13, the disinfection transport vehicle 1 is steadily stopped on the lifting platform 4.

[0029] In a specific embodiment, such as Figure 3 As shown, the lifting mechanism 2 is a scissor lifting mechanism. The lifting mechanism 2 is equipped with a hydraulic rod 14, which controls the lifting mechanism 2 to lift and lower, thereby raising the disinfection transport vehicle 1.

[0030] The height of the light-shielding plate 7 is 5cm to 10cm. This allows the light-shielding plate 7 to effectively block the light emitted by the through-beam photoelectric switch 3, so that the PLC controller can control the lifting mechanism 2 to rise and fall through the signal from the through-beam photoelectric switch 3.

[0031] Of course, there may be other implementations of this utility model. Based on this implementation, other implementations obtained by those skilled in the art without any creative effort are all within the scope of protection of this utility model.
