Description

Technical Field

[0001] This invention relates to the field of food sterilization equipment technology, and in particular, to a food sterilization conveying device and a food sterilization device. Background Technology

[0002] In food processing, it is often necessary to sterilize pre-packaged small-sized food products to reduce bacteria on the outer packaging and ensure its hygiene. This is typically done by loading food materials onto trays, stacking the trays several times, and then manually feeding or pulling the trays into or out of the sterilizer, which is labor-intensive. Alternatively, a receiving rack is usually used to connect with a track inside the sterilizer to accurately feed or receive trays. To avoid structural interference, the receiving rack must be manually removed when opening or closing the sterilizer door, and then re-aligned with the sterilizer, repeating this process repeatedly, which is also labor-intensive and cumbersome. Summary of the Invention

[0008] Furthermore, the conveying mechanism includes a sliding seat, a lifting block, a second telescopic drive mechanism, and a conveying drive mechanism; the sliding seat is slidably mounted on the receiving frame in the front-to-back direction, and the conveying drive mechanism is used to drive the sliding seat to slide back and forth; the lifting block is movably mounted on the sliding seat, and the bottom of the base is provided with an insertion hole, and the lifting block aligned with the insertion hole can rise and insert into the insertion hole to drive the base to move; a return spring is installed between the lifting block and the sliding seat to apply a downward elastic force to the lifting block; the second telescopic drive mechanism has a horizontally telescopic output shaft, and a wedge is connected to the output shaft, and the wedge can extend and push the lifting block to rise.

[0009] Furthermore, it also includes an unlocking mechanism; when two base trays facing the same direction approach each other in the front-rear direction, they can be connected to each other to achieve overall movement; the unlocking mechanism is used to disconnect the base tray in the third position from the previous base tray connected to it; the third position is between the first position and the second position; when the conveying mechanism conveys the base tray to the third position, the previous adjacent base tray is in the second position.

[0010] Furthermore, the base includes: a support base for supporting a food tray;

[0011] A fixed buckle is located on the rear side of the bottom of the support base; a movable component has a locked state that engages with the fixed buckle on the adjacent front support base, allowing the two adjacent support bases to move as a whole; the movable component is movably installed on the front side of the bottom of the support base to be able to move out of the locked state; a state holding component is used to apply a force to the movable component to maintain the locked state; an unlocking component is movably installed on the bottom of the support base; the unlocking mechanism is used to push the unlocking component to move, thereby causing the unlocking component to move out of the locked state and disconnect the two adjacent support bases.

[0012] Furthermore, the fixing buckle has a through hole for inserting the movable part, and a slot is provided on one side of the through hole. The movable part is rotatably mounted on the support base. The movable part has a latching part. In the locked state, the latching part is inserted into the slot.

When 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 invention.

[0043] Please refer to Figure 3 A preferred embodiment of the present invention provides a food sterilization and conveying device, comprising a frame 100, a lifting frame 200, a receiving frame 300, a base 400, and a conveying device.

[0044] The frame 100 is equipped with a lifting drive mechanism 110; the lifting frame 200 is movably mounted on the frame 100 and connected to the lifting drive mechanism 110 so that it can be lifted and driven. The lifting drive mechanism 110 can be a telescopic cylinder or a telescopic hydraulic cylinder. The telescopic end of the telescopic cylinder or the telescopic hydraulic cylinder is connected to the lifting frame 200 to drive its lifting and lowering; the receiving frame 300 is connected to the lifting frame 200 and is used to support the base 400; the conveying device is used to send the base 400 at the first position 401 on the receiving frame 300 into the sterilizer 800 and to convey the base 400 in the sterilizer 800 to the first position 401.

[0045] This invention provides a food sterilization conveying device that uses a conveying device to feed the bottom tray 400 at a first position on the receiving rack 300 into the sterilizer 800 and to convey the bottom tray 400 inside the sterilizer 800 to the first position, thereby achieving automatic feeding or pulling out of the bottom tray 400 and improving automation. In addition, to avoid interfering with the opening and closing of the sterilizer door 820, a lifting drive mechanism 110 drives the lifting frame 200 and the receiving rack 300 to rise and fall. Thus, when it is necessary to open or close the sterilizer door 820, the receiving rack 300 can be raised and lowered to a position that avoids the opening and closing path of the door 820. When it is necessary to receive or feed materials, the receiving rack 300 can be reset, without the need for manual movement of the receiving rack 300, further improving automation and reducing labor intensity.

[0046] Reference Figure 3 In some embodiments of the present invention, the conveying device includes a conveying mechanism 500 and a push-pull mechanism 600; the conveying mechanism 500 is used to drive the base tray 400 to move between a first position 401 and a second position 402, with the first position 401 located behind the second position 402; the push-pull mechanism 600 is used to push the base tray 400 at the second position 402 into the sterilizer 800 or to pull the base tray 400 out of the sterilizer 800 to the second position 402. That is, the push-pull mechanism 600 ultimately pushes the base tray 400 into and pulls it out of the sterilizer, while the conveying mechanism 500 moves the base tray 400 outside the sterilizer.

[0047] Reference Figure 3 In some embodiments of the present invention, the receiving rack 300 is provided with two first track plates 310 spaced apart from each other. A limiting plate 320 is provided on the opposite side of the two first track plates 310. The bottom of the base 400 is provided with two rows of rollers 417, which support the two first track plates 310 respectively. The limiting plate 320 is used to limit the rollers 417, preventing them from detaching from the first track plates 310, while the rollers 417 reduce the resistance to movement of the base 400. The sterilizer 800 is provided with two second track plates 810. The first track plate 310 can rise with the lifting frame 200 to be aligned with the height of the second track plate 810, thereby achieving track docking inside and outside the sterilizer. This allows the base 400 on the first track plate 310 to be accurately pushed onto the second track plate 810 inside the sterilizer 800. For stable support, a baffle is provided at the rear end of the first track plate 310 to block the base 400, preventing the base 400 from shifting out of the first track plate 310 from the rear.

[0048] Understandably, to facilitate loading and unloading, a receiving rack 300 extends from the rear end of the first track plate 310. The base 400 of the first position 401 rests on the receiving rack 300 extending from the rear end of the first track plate 310, thus allowing the AGV trolley to move and load / unload materials in the space between and below the two first track plates 310 at this position. Figure 1 and Figure 2 As shown, the first position 401 is the position for loading and unloading materials using an AGV trolley, and the second position 402 is the position for entering and exiting the pot.

[0049] Reference Figure 4 In some embodiments of the present invention, the push-pull mechanism 600 includes a rotary drive mechanism 610 and a first telescopic drive mechanism 620; the rotary drive mechanism 610 is slidably mounted on the receiving rack 300 in the front-to-back direction, and the rotary drive mechanism 610 has a rotatable rotating shaft, the rotating shaft being connected to a radially protruding hook block 611. Specifically, the rotary drive mechanism 610 can be a rotary motor or a rotary cylinder, using the rotary motor or rotary cylinder to drive the rotating shaft and hook block 611 to rotate. Figure 7 As shown, the bottom of the base 400 is provided with a hook hole 415. When the hook block 611 is aligned with the hook hole 415, the hook block 611 can rotate and embed into the hook hole 415, thereby driving the base 400 to move back and forth together. The first telescopic drive mechanism 620 is installed on the receiving rack 300. The first telescopic drive mechanism 620 is connected to the rotary drive mechanism 610 to drive the rotary drive mechanism 610 to slide back and forth, thereby pushing the base 400 in the second position into the sterilizer 800 or pulling the base 400 in the sterilizer 800 out to the second position. Specifically, the first telescopic drive mechanism 620 is a telescopic cylinder, thereby driving the rotary drive mechanism 610 to slide back and forth, and driving the base 400 hooked by the hook block 611 to move back and forth together.

[0050] It is understandable that, in order to achieve stable push-pull base 400, two sets of first telescopic drive mechanism 620 and rotary drive mechanism 610 are arranged at left and right intervals to achieve multi-position push-pull. In order to achieve sliding stability, the two rotary drive mechanisms 610 can be connected together through connecting frame 612. The bottom of connecting frame 612 is provided with slider, and the upper end of receiving frame is provided with first slide rail 330 adapted to slider, thereby achieving sliding guidance.

[0051] Reference Figure 3 and Figure 5In a specific embodiment of the present invention, the conveying mechanism 500 includes a sliding seat 510, a lifting block 520, a second telescopic drive mechanism 530, and a conveying drive mechanism 540. The sliding seat 510 is slidably mounted on the receiving rack 300 in the front-back direction. Specifically, the receiving rack 300 is provided with a second slide rail 340 extending in the front-back direction. A slider adapted to the second slide rail 340 is detachably connected to the bottom of the sliding seat 510, thereby achieving sliding guidance. In addition, to limit the stroke, a stroke limit stop structure, such as a baffle or a stop block, can be set at the rear end of the second slide rail 340 to prevent the sliding seat 510 from sliding out of the second slide rail 340. The conveying drive mechanism 540 is used to drive the sliding seat 510 to slide back and forth. Specifically, the conveying drive mechanism 540 is a transmission chain. Part of the chain links are connected and fixed to the sliding seat 510 by fasteners. The transmission chain is sleeved on a sprocket, and the sprocket is connected to a drive motor, thereby driving the sprocket to rotate. The rotation of the transmission chain drives the sliding seat 510 to move back and forth. The lifting block 520 is movably mounted on the sliding seat 510, as shown in the reference. Figure 7 The bottom of the base 400 is provided with an insertion hole 416. The lifting block 520, which is aligned with the insertion hole 416, can rise and insert into the insertion hole 416, thereby driving the base 400 to move. The sliding seat 510 is provided with an movable hole for the lifting block 520 to move up and down. A return spring 550 is installed between the lifting block 520 and the sliding seat 510 to apply a downward elastic force to the lifting block 520. Screws are connected to both the lifting block 520 and the sliding seat 510. Both ends of the return spring 550 are hooked on the screws, thereby applying a downward elastic force to the lifting block 520. The second telescopic drive mechanism 530 has a horizontally telescopic output shaft. A wedge 531 is connected to the output shaft. The wedge 531 can extend and move to push the lifting block 520 to rise. The second telescopic drive mechanism 530 is a telescopic cylinder, thereby driving the wedge 531 to move horizontally. The outer end of the wedge block 531 is provided with an inclined surface. When it extends, the inclined surface can push the lifting block 520 to rise and insert into the insertion hole 416. When it retracts, the lifting block 520 descends and exits the insertion hole 416 under the action of the reset spring 550.

[0052] Reference Figure 3In some embodiments of the present invention, an unlocking mechanism 700 is also included; two bottom trays 400 facing the same direction can be connected to each other to achieve overall movement when they approach each other in the front-back direction; the unlocking mechanism 700 is used to disconnect the bottom tray 400 at the third position 403 from the previous bottom tray 400 connected to it; the third position 403 is between the first position 401 and the second position 402; when the conveying mechanism 500 conveys the bottom tray 400 to the third position, the previous adjacent bottom tray 400 is in the second position. The bottom trays 400 can be connected in series, so that they can move as a whole. When unloading, all bottom trays 400 can be pulled out together, making it convenient to pull out the innermost bottom tray, reducing the travel and overall size of the push-pull mechanism 600. When it is necessary to separate the outermost bottom tray 400 for unloading, only the unlocking mechanism 700 needs to be automatically unlocked.

[0053] The following describes the process of removing the bottom tray 400 from the pot. Multiple bottom trays 400 are typically connected in series in the pot. When it's time to remove the pot, the first telescopic drive mechanism 620 drives the rotary drive mechanism 610 to extend, aligning the hook block 611 with the hook hole 415 of the outermost (rearmost) bottom tray 400. Then, the rotary drive mechanism 610 drives the hook block 611 to rotate and embed into the hook hole 415. Next, the first telescopic drive mechanism 620 drives the rotary drive mechanism 610 to retract, thus moving the outermost (rearmost) bottom tray 400 to the second position 402. Then, the sliding seat 510 moves until the lifting block 520 aligns with the insertion hole 416 of the bottom tray 400 at the second position 402. Then, the second telescopic drive mechanism 530 extends, driving the lifting block 520 to rise and insert into the insertion hole 416. Finally, the conveying drive mechanism 540 drives the sliding seat 510, carrying the outermost bottom tray 400, to the third position 403, where it stops, achieving the desired result. Figure 1 As shown, the second base support 400 is in the second position. Then, the rotation drive mechanism 610 drives the hook block 611 to rotate and disengage from the hook hole 415. The unlocking mechanism 700 unlocks both base supports 400. The conveying drive mechanism 540 drives the sliding seat 510 to continue moving backward until the outermost base support 400 reaches the first position 401, achieving the desired state. Figure 2As shown, the second telescopic drive mechanism 530 then retracts, the lifting block 520 descends and disengages from the insertion hole 416, and the outermost base tray 400 awaits the AGV trolley to transport the base tray 400 at the first position 401. Then, the sliding seat 510 transports the base tray 400 still at the second position to the third position. If there is another base tray 400 connected to the front of this base tray 400, it is unlocked by the unlocking mechanism 700 and continues to move forward to the first position 401. If there is no base tray 400 connected to the front of this base tray 400, it directly moves forward to the first position 401 to await transport by the AGV trolley. This achieves continuous transport, and the series connection of the base trays 400 slowly brings them out one by one. Without the series connection, the innermost base tray 400 would require a long travel distance for the push-pull mechanism 600 to be transported out, resulting in a larger overall size of the push-pull mechanism 600, occupying more space, and making equipment placement inconvenient.

[0054] Reference Figure 7 In a specific embodiment of the present invention, the base 400 includes a support base 410, a fixing buckle 420, a movable part 430, a status holding part 440, and an unlocking component 450.

[0055] The support base 410 supports the food tray 101; the fixing buckle 420 is located on the rear side of the bottom of the support base 410; the movable member 430 has a locked state that engages with the fixing buckle 420 on the adjacent support base 410, allowing the two adjacent support bases 410 to move as a whole, thereby enabling the adjacent trays 400 to be connected end-to-end; the movable member 430 is movably installed on the front side of the bottom of the support base 410 to be movable out of the locked state; the state holding member 440 applies a force to the movable member 430 to maintain the locked state; the unlocking component 450 is movably installed on the bottom of the support base 410; the unlocking mechanism 700 pushes the unlocking component 450 to move, thereby causing the unlocking component 450 to move the movable member 430 out of the locked state, thus disconnecting the two adjacent support bases 410. Specifically, the unlocking component 450 is located on one side of the fixing buckle 420, and the unlocking component 450 can disengage the movable member 430 on the other support base 410 that engages with the fixing buckle 420 from the locked state. The movable component 430 is connected to the fixing buckle 420 on the adjacent front support base 410, allowing the two adjacent base supports 400 to move together as a whole. The state holding component 440 applies a locking force to the movable component 430, ensuring a stable connection between the movable component 430 and the fixing buckle 420, as well as a stable series connection between the base supports 400. When it is necessary to separate the adjacent base supports 400, the unlocking mechanism 700 simply operates the unlocking component 450 to push the locked movable component 430 out of the locked state, making unlocking simple.

[0056] Reference Figure 8 and Figure 9 In a further embodiment of the present invention, the fixing buckle 420 has a through hole 421 for the insertion of the movable member 430. A slot 422 is provided on one side of the through hole 421. The movable member 430 is rotatably mounted on the support base 410. The movable member 430 has a latching part 431. In the locked state, the latching part 431 is engaged with the slot 422. Thus, by utilizing the cooperation between the latching part 431 and the slot 422, the latching part 431 hooks the fixing buckle 420, allowing two adjacent support bases 410 to be connected in series and move back and forth synchronously. The movable member 430 is hinged to the support base 410 via a hinge shaft 432. The state holding member 440 is a torsion spring sleeved on the hinge shaft 432. This applies an elastic force to the movable member 430, so that the movable member 430 remains in the locked state when no external force is applied. Specifically, to facilitate the installation of the torsion spring, a mounting clearance is provided in the middle of the hinge of the movable member 430 to expose the hinge shaft and provide sufficient space for the installation of the torsion spring. Specifically, the support base 410 has a mounting base 411 fixedly provided at its bottom. The movable member 430 is hinged to the mounting base 411. The torsion spring has two working arms 441. The two working arms 441 abut against the side of the movable member 430 facing away from the buckle part 431 and the mounting base 411 respectively, thereby driving the buckle part 431 to remain embedded in the bayonet 422. The mounting base 411 facilitates the hinge of the movable member 430. The mounting base 411 has an installation space for the movable member 430 to be embedded.

[0057] Reference Figure 8 and Figure 9In a further embodiment of the present invention, the unlocking component 450 includes a push rod 451 and a compression spring 452. The push rod 451 is movably mounted on the bottom of the support base 410 along its own length direction. The push rod 451 is aligned with the latch 422 so that it can be inserted into the latch to disengage the latch portion 431 embedded in the latch 422, thereby unlocking the fixed buckle 420 and the movable part 430, thereby allowing the two adjacent support bases 410 to be separated. The bottom of the support base 410 is provided with a guide block 412 for the push rod 451 to move through. The guide block 412 is provided with a mechanism adapted to the push rod 451. The guide hole is provided to guide the movement of the push rod 451. The end of the push rod 451 facing away from the latch 422 has a rod head 453. A compression spring 452 is sleeved on the push rod 451, with both ends abutting against the rod head 453 and the guide block 412 respectively. This ensures that when no external force is applied, the push rod 451 will not push the latch part 431 to move, maintaining a stable locking state. When the external force disappears, the compression spring 452 pushes the push rod 451 to automatically reset, allowing the push rod 451 to disengage from the latch part 431 and leave the latch 422, thus not affecting the subsequent insertion of the latch part 431 into the latch 422. Specifically, the unlocking mechanism 700 is a telescopic cylinder. The telescopic rod of the telescopic cylinder extends to push the push rod 451 on the base 400 in the second position 402 into the latch, disengaging the latch part 431 of the other base 400 embedded in the latch 422, thereby releasing the connection and locking of the two connected bases 400.

[0058] Specifically, a first limiting structure 454 is provided on the push rod 451. The first limiting structure 454 is located on the side of the guide block 412 opposite to the compression spring 452. The first limiting structure 454 can move to abut against the guide block 412 to limit the travel of the push rod 451 away from the latch 422, so that the push rod 451 will not disengage from the guide block 412 when it resets, and the position of the push rod 451 is stable when it resets. Utilizing the combined action of the first limiting structure 454 abutting against the guide block 412 and the compression spring 452, the push rod 451 is stable in position and will not move arbitrarily when no external force is applied. Specifically, the first limiting structure 454 is a screw that passes radially through the push rod 451, and a nut is threadedly connected to one end of the screw that passes through the push rod 451 to fix it to the push rod 451. The outer peripheral wall of the push rod 451 is provided with a second limiting structure 455. The second limiting structure 455 is located on the side of the first limiting structure 454 near the bayonet 422. The second limiting structure 455 can move to abut against the fixing buckle 420 to limit the depth of the push rod 451 inserted into the bayonet 422, so as to avoid the push rod 451 being inserted too deeply, causing structural interference or structural damage. Specifically, the second limiting structure 455 is a bushing fixed on the push rod 451. The bushing profile is larger than the bayonet 422, so the bushing cannot enter the bayonet 422, thereby limiting the stroke of the rod 451 inserted into the bayonet 422.

[0059] To facilitate stable handling of the AGV trolley, the support base 410 has a positioning seat 413 at its bottom. The positioning seat 413 has positioning holes 414 with bottom openings. The AGV trolley has a liftable support platform at its upper end, with positioning protrusions on the platform that fit the positioning holes 414. This ensures proper positioning and support during handling, preventing misalignment that could cause the base 400 to tip over and improving handling stability. Specifically, the positioning holes 414 are rectangularly distributed, enabling multi-position positioning.

[0060] Furthermore, the end of the latching part 431 is provided with a guide surface 433, so that the latching part 431 can gradually rotate under the action of the guide surface 433 during the process of inserting the latching part 431 into the through hole 421 so that the latching part 431 can be fully inserted into the through hole 421. The guide surface 433 can be a shoe upper or a curved surface. During insertion, the latching part 431 is not aligned with the through hole 421. Under the action of the guide surface 433, the latching part 431 rotates to fully insert into the through hole 421 to avoid structural interference. When the latching part 431 aligns with the slot 422, under the action of the state-holding member 440, the latching part 431 rotates and embeds into the slot 422, achieving the connection between the fixed buckle 420 and the movable part 430. Furthermore, during operation, there is no need for manual operation to rotate the latching part 431 to avoid structural interference. When the subsequent support base 410 moves towards the previous support base 410, the guide surface 433 and the state-holding member 440 can be used to automatically connect the fixed buckle 420 and the movable part 430 without additional manual operation. Additionally, it can be understood that to ensure the movable part 430 is stable and aligned with the through hole 421 before insertion, such as... Figure 9 As shown, the movable part 430 has a limiting plane 434. Under the action of the state holding member 440, the limiting plane 434 of the movable part 430 partially abuts against the mounting base 411, thereby ensuring that it remains in place. Figure 9 This allows for alignment with the insertion of via 421.

[0061] Reference Figure 3 and Figure 6In some embodiments of the present invention, in order to ensure precise positioning of the base 400 (support base 410) when it moves forward, thereby enabling accurate series connection between the base 400s, the receiving rack 300 is provided with guide mechanisms 900 on both sides of the first track plate 310. The guide mechanism 900 includes a movable arm 910, a guide wheel 920, and a third telescopic drive mechanism 930. The middle part of the movable arm 910 is rotatably mounted on the receiving rack 300 along the vertical axis. The guide wheel 920 is installed at one end of the movable arm 910 near the base 400, and the other end is connected to the telescopic end of the third telescopic drive mechanism 930. The guide wheel 920 is used to achieve left and right limit guidance when the base 400 moves forward. When the unloading base 400 needs to move backward, the telescopic drive mechanism 930 retracts from the movable arm 910, thereby moving the guide wheel 920 away from the movement path of the base 400 and avoiding interference with the unloading of the base 400. Since the base supports 400 do not need to be connected when they come out, but need to be separated, the absence of guide wheels 920 has no impact.
