Description

Technical Field

[0001] The present invention relates to the technical field of cold chain transportation and loading and unloading, and in particular to automatic loading and unloading equipment for cold chain transportation of chicken fillets. Background Art

[0002] Chicken fillets are frozen foods. According to relevant national standards, they should be stored at a temperature of less than or equal to -18°C. In such a low-temperature environment, the growth and reproduction of microorganisms can be effectively inhibited, and the speed of chemical reactions such as fat oxidation and water loss in chicken fillets can be slowed down, thereby maintaining the taste, flavor and nutritional value of chicken fillets and extending their shelf life. However, there must be loading and unloading processes during the transportation of chicken fillets. During this period, the chicken fillets will be exposed to room temperature. If the time is too long, the freshness of the chicken fillets will not be high. Therefore, chicken fillets must be loaded and unloaded quickly, but the current loading and unloading is slow, inefficient, and takes a long time. The existing loading and unloading has adopted equipment loading and unloading, but the equipment is not integrated and cannot be loaded and unloaded continuously. Moreover, it is very difficult to transport the track from the body to the ground. It has a slope, and the box body is not easy to control when it slides down, making loading and unloading relatively difficult. Summary of the invention

DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0033] like Figure 1-10 As shown, the present invention proposes an automatic loading and unloading device for cold chain transportation of chicken fillets, comprising an automatic loading and unloading device box 1, a first mechanical arm loading and unloading mechanism 3, a second mechanical arm loading and unloading mechanism 5, a first transport roller belt 7, a second transport roller belt and a controller;

[0034] A first lifting platform 6 is provided in the rear half of the automatic loading and unloading equipment box 1, and a second lifting platform 8 is provided in the front half. The bottoms of the first lifting platform 6 and the second lifting platform 8 are lifted and lowered by a lifting hydraulic cylinder group. A first transport roller belt 7 is placed on the first lifting platform 6, and the right end of the first transport roller belt 7 is fixed to the right side wall of the automatic loading and unloading equipment box 1. A second transport roller belt is provided on the second lifting platform 8, and the left end of the second transport roller belt is fixed to the left side wall of the automatic loading and unloading equipment box 1. A controller is provided under the second lifting platform 8.

[0035] The purpose of setting two transport roller belts is to facilitate the installation of the second robotic arm loading and unloading mechanism 5 at the rear. Since the automatic loading and unloading equipment box 1 is placed on the ground, it cannot be moved like the first robotic arm loading and unloading mechanism 3. Because the first robotic arm loading and unloading mechanism 3 can be placed in the cold chain transport vehicle, it has support, and when the second robotic arm loading and unloading mechanism 5 is pulled out, there will be a distance from the ground, and the support table is not stable and inconvenient to operate. It is fixed on the outer wall of the automatic loading and unloading equipment box 1, with good stability, and it is convenient to operate the second transport roller belt to carry the goods so as to take the goods away.

[0036] An open installation space is provided at the rear half of the left end of the automatic loading and unloading equipment box 1, a first pull-out plate 61 is provided at the left end of the first lifting platform 6, and the first pull-out plate 61 can be pulled out from the left end of the first lifting platform 6, the bottom of the first mechanical arm loading and unloading mechanism 3 is fixed on the first pull-out platform 61, and the second mechanical arm loading and unloading mechanism 5 is installed on the rear half side wall of the right end of the automatic loading and unloading equipment box 1, and a second pull-out platform 81 is provided at the right end of the second transport roller belt 8, and the first pull-out platform 61 and the second pull-out platform 81 are both provided with an inserting plate 611 at the rear side to be inserted into the corresponding first lifting platform 61 and the second lifting platform 81;

[0037] Since the heights of the cold chain transport vehicles are not exactly the same, and the first mechanical arm loading and unloading mechanism 3 needs to be moved according to the unloading position, an installation space is provided for easy removal. The second pull-out platform 81 is pulled out and moved to the cold chain transport vehicle.

[0038] The automatic loading and unloading equipment box 1 is provided with an inward-pushing cylinder group 2 on the front and rear side walls near the left end, and a sliding door 11 is provided on the front half of the right end of the automatic loading and unloading equipment box 1; when the inward-pushing cylinder group 2 is transported to the side of the first lifting platform 6, it will stop rotating for 1-2 seconds through automatic detection of the goods and transport them to a fixed position (the position set by the system), and the inward-pushing cylinder group 2 will be directly pushed to the second transport roller belt (the first transport roller belt is slightly higher than the second transport roller belt when loading, and the opposite is true when unloading).

[0039] The first mechanical arm type loading and unloading mechanism 3 and the second mechanical arm type loading and unloading mechanism 5 have the same structure and function. The first mechanical arm type loading and unloading mechanism 3 includes a control bottom box 321, a rotating shaft 32, a mechanical arm, a rotating servo motor 40 and a suction box plate 4. The control bottom box 321 is equipped with a rotating shaft 32, the bottom end of the mechanical arm is fixed to the top of the rotating shaft 32, the front end of the mechanical arm is rotatably equipped with a rotating servo motor 40, an angle adjustment hydraulic cylinder 31 is connected between the front end of the mechanical arm and the rotating servo motor 40, a suction box plate 4 is installed on the rotating shaft of the rotating servo motor 40, a plurality of negative pressure suction cups 41 are arranged at the bottom of the suction box plate 4, a shooting camera 44 is arranged at the middle position of the bottom of the suction box plate 4, a negative pressure suction pipe connected to the plurality of negative pressure suction cups 41 is arranged on the suction box plate 4, a control line is arranged on the rotating servo motor 40, and the negative pressure suction pipe and the control line are connected to the control bottom box along the mechanical arm;

[0040] The control bottom box 321, the rotating shaft 32, the mechanical arm, and the rotating servo motor 40 are all existing, and the box body is now adsorbed and transferred to the conveyor belt. However, the adsorption structure is different, and the middle shooting camera 44 is used to compare the position of the goods, which is convenient for moving and picking up the goods.

[0041] The first transport roller belt 7 and the second transport roller belt are both stretch roller conveyor belts;

[0042] The controller is used to control the operation of the entire device.

[0043] The first mechanical arm loading and unloading mechanism 3 is positioned to dock with the rear door of the cold chain transport vehicle, and the height of the first lifting platform 6 is adjusted according to the height of the inner bottom wall surface of the docked cold chain transport vehicle, so that the first pull-out plate 61 can be just placed on the inner bottom wall surface of the cold chain transport vehicle after being pulled out, and the second lifting platform 8 is adjusted according to the height of the first lifting platform 6, so as to transport the chicken fillet cold chain storage box to each other. It can adapt to a variety of cold chain transport vehicles of different sizes, and it can better adjust the height.

[0044] The two sides of the first transport roller belt 7 are composed of a plurality of cross frames 71, and a universal wheel is installed at the supporting position of the bottom end of the cross frame 71. The middle position between the cross frames 71 is rotatably connected, and the outer sides of the top ends of adjacent cross frames 71 are connected by connecting rods 711, and the connecting rods 711 are rotatably connected to the top of the cross frame 71. The multiple cross frames 71 on both sides of the first transport roller belt 7 correspond to each other, and rollers 72 are rotatably installed between the top ends of the corresponding cross frames 71. Both ends of the rollers 72 are rotatably installed on the inner side of the top end of the cross frame 71. All the rollers 72 are covered with a double pulley at the end of the same side, and a rotating rod 73 is connected between the cross frames 71 corresponding to the two sides between the crossing positions. Two guide rollers 74 distributed up and down are provided on the rotating rod 73 below the double pulleys. A belt is covered between the double pulleys between the same cross frame 71, and the upper and lower sides of the belt pass through the upper and lower guide rollers 74 respectively. A belt is covered between the double pulleys between the adjacent cross frames 71, and the outermost double pulleys are driven by a belt through a driving motor.

[0045] The first transport roller belt 7 can occupy a short distance when folded and stored, and can be pulled out for a long distance after being pulled out. It is different from the existing transport roller belt 7, and its disadvantage is that it can only transport larger cargo boxes with a width of more than 60 cm. However, for small cargo boxes, the existing transport roller belt can also be replaced. Figure 7 It can be seen that after the same cross frame 71 is pulled apart, the distance between the two rollers 72 is relatively large. The first conveying roller belt 7 and the second conveying roller belt are arranged to be disassembled from the automatic loading and unloading equipment box so that other structures with stretching roller conveyor belts can be replaced. That is, it is easy to replace.

[0046] The suction box plate 41 includes a chassis 412, a rubber suction cup 411, an air suction nozzle 43, a suction pipe 431 and an elastic telescopic rod 42. The rubber suction cup 411 is fixed to the bottom of the chassis 412, the bottom end of the elastic telescopic rod 42 is fixed to the top of the chassis 412, the top of the elastic telescopic rod 42 is fixed to the bottom of the suction box plate 41, a round hole is provided in the middle of the rubber suction cup 411 and the air suction nozzle 43 is plugged in the round hole, the suction pipe 431 is installed on the air suction nozzle 43 and moves through the elastic telescopic rod 42, and multiple suction pipes 431 are connected to the negative pressure suction pipe.

[0047] The elastic telescopic rod 42 prevents the rubber suction cup 411 from pressing against the box body and damaging the box body. The elastic telescopic rod 42 has a buffering effect and can also improve the adsorption effect. The suction tube 431 absorbs air to prevent it from falling after being sucked. When it is put down, it does not absorb air and falls automatically.

[0048] The first lifting platform 6 is not provided with the first pull-out plate 61 at the left end, and the control bottom box 321 of the first robotic arm loading and unloading mechanism 3 can be moved away from the first lifting platform 6. At this time, the first pull-out plate 61 is docked to the rear door of the cold chain transport vehicle and is flush with the bottom wall inside the cold chain transport vehicle.

[0049] The pull-out plate is easy to operate, but the first mechanical arm loading and unloading mechanism 3 can only be in the middle position when entering the cold chain transport vehicle. The first pull-out plate 61 is cancelled and can be placed as needed. Moreover, the first pull-out plate 61 is no longer needed at this time, and the first transport roller belt 7 can be directly pulled into the cold chain transport vehicle.

[0050] After being pulled out, the upper surfaces of the insert plates 611 on the first pull-out platform 61 and the second pull-out platform 81 are padded with gaskets 612 , so that the upper surfaces of the gaskets 612 are flush with the upper surfaces of the first pull-out platform 61 and the second pull-out platform 81 .

[0051] After pulling, the surface will be sunken and uneven. The gasket 612 can make it level.

[0052] The automatic loading and unloading equipment box 1 is provided with two detectors in the same straight line on the front and rear inner walls near the left end. The detector is an infrared distance detector. After the first detector detects that the box has moved to the designated position, the movement speed is slowed down. When the second distance detector detects, the operation can be stopped instantly. At this time, the inner push cylinder group 2 is started to push and transfer to another transport roller belt, and then continue to transport and transfer the next box.

[0053] After the second pull-out platform 81 is pulled out, a support frame with adjustable height is placed on the ground at the bottom of the second pull-out platform 81, and the top of the support frame is against the bottom of the second pull-out platform 81. If the goods are too heavy, the support is used to improve the levelness. Figure 6 An anti-drop plate 70 is arranged on the cross frame of the second transport roller belt to prevent it from falling.

[0054] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
