A storage device for luncheon meat canning and its usage method

Abstract

This invention relates to the field of canned food storage, specifically to a storage device and its method for producing luncheon meat cans. After a tray is released from the high side of an inclined placement plate, it continuously accelerates under gravity, often reaching a high speed at the low end. The tray then rigidly collides with the support frame or the limiting structure at the end, resulting in a large impact force that can easily cause displacement or damage to the cans within the tray. Simultaneously, the tray will oscillate back and forth on the support frame after the impact, making it difficult to quickly and stably settle. In this luncheon meat can production storage device and its method, when the sliding seat and the side support undergo relative displacement, the limiting ball bearings are subjected to a gradually increasing radial constraint force within the V-shaped insert groove, thereby generating a damping force that increases with the displacement. This progressive damping causes the can tray's speed to gradually decrease in the final stage of its journey before settling on the support frame, ultimately achieving a smooth stop.

Description

Technical Field

[0001] This invention relates to the field of canned food storage, specifically to a storage device for luncheon meat production and its usage method. Background Technology

[0002] In the production and packaging of foods such as luncheon meat, in order to facilitate the temporary storage and transfer of semi-finished or finished products, the canned products are usually neatly stacked in special pallets and then transferred to shelves for storage. In order to improve the utilization of workshop space and reduce the burden of manual handling, multi-layer inclined shelves are widely used.

[0003] This type of shelving typically includes a multi-layer structure arranged vertically. Each layer is equipped with an inclined placement board, with the higher side of the placement board facing the operator and the lower side adjacent to the support frame. After the operator places the canned food pallet on the higher side of the inclined placement board, the pallet automatically slides to the lower side under its own weight, thus completing one storage action.

[0004] To automate pallet placement across different shelf heights, some existing shelving systems are equipped with lifting frames at the support supports, such as lifting devices driven by screw slides. A typical workflow is as follows: operators or conveying equipment first place the canned food pallet on the higher side of an inclined placement shelf. After placement, the pallet slides down the shelf to the lower support support. The lifting frame then raises the pallet from the support support to the target shelf height for placement or further transport. This sliding-then-lifting operation reduces the labor intensity of manual layer-by-layer handling.

[0005] The following problems exist in the existing technology and have not been adequately resolved: After being released from the higher side of the inclined placement platform, the pallet continues to accelerate under the influence of gravity, often reaching a high speed when it reaches the lower end. The pallet then undergoes a rigid collision with the support frame or the limiting structure at the end, resulting in a significant impact force that can easily cause displacement or damage to the cans inside the pallet. Simultaneously, the pallet will oscillate back and forth on the support frame after the impact, making it difficult to quickly and stably settle into its final position. This not only affects the continuous storage of subsequent pallets but also interferes with the gripping and positioning accuracy of the lifting frame. In actual operation, if the previous pallet has not been taken away by the lifting frame or has not come to a stable stop, and the operator mistakenly releases the next pallet from the high side, the next pallet will slide down at high speed and collide violently with the previous pallet. This may not only cause the cans to deform or the packaging to break, but also pose a safety risk of the pallet tipping over. Summary of the Invention

[0006] The purpose of this invention is to provide a storage device and its method of use for luncheon meat canning production, in order to solve the problems mentioned in the background art. To achieve the above objective, this invention provides the following technical solution: A storage device for luncheon meat canning production, comprising a multi-layer inclined shelf, wherein the multi-layer inclined shelf includes a placement rack located on the ground, the placement rack being configured as a multi-layer structure in the vertical direction, each layer being equipped with an inclined placement plate, a support bracket for supporting can trays being fixed to one outer wall of the placement rack, the higher side of the placement plate facing the operator, and the lower side adjacent to the support bracket, the support bracket being provided with a lifting frame driven by a screw slide table for lifting the can trays to the corresponding layer height position, a buffer anti-collision component integrated on the side wall of the placement rack and located at the lower end of the inclined placement plate, two sets of buffer anti-collision components being symmetrically arranged on both sides of each layer of placement plate, the two sets of buffer anti-collision components being mirror-distributed with respect to the longitudinal central axis of the placement plate.

[0007] Preferably, the buffer and anti-collision assembly includes a support base fixedly disposed on the side wall of the placement rack, a sliding seat slidably connected to the support base, the sliding seat being capable of reciprocating along the length direction of the support base, a first elastic element disposed between the sliding seat and the support base, one end of the first elastic element abutting the sliding seat and the other end abutting the support base, and a buffer abutting plate extending from the sliding seat toward the placement plate, the buffer abutting plate being used to directly contact the sliding can tray.

[0008] Preferably, a side bracket is slidably connected to the outer wall of the sliding seat, the side bracket is movable relative to the sliding seat along its length, and a second elastic element is provided between the sliding seat and the side bracket, the second elastic element keeping the sliding seat and the side bracket close to each other in the initial state.

[0009] Preferably, a limiting baffle is fixedly provided on the support base. The limiting baffle is located on the moving path of the buffer abutment plate after being pressed. A second guide groove is provided on the limiting baffle. The second guide groove includes a straight groove section extending along the moving direction and an arc-shaped locking section located at the end of the straight groove section. A plurality of limiting balls are embedded in the arc-shaped locking section. A V-shaped opening is provided on the limiting baffle. Each limiting ball is floatingly disposed in the embedding groove by an elastic sheet. A friction pad is covered on top of the limiting balls.

[0010] Preferably, a locking swing arm is rotatably connected to the side bracket via a rotating shaft. A torsion spring is sleeved on the rotating shaft. The torsion spring causes the locking swing arm to always apply a preload towards the sliding seat. A first sliding roller and a second sliding roller are arranged opposite to each other on the locking swing arm. The first sliding roller is located on the side closer to the sliding seat, and the second sliding roller is located on the side closer to the limiting baffle.

[0011] Preferably, the sliding seat has a first guide groove, the first guide groove includes a snap-fit ​​section and a sloped section that is smoothly connected to the snap-fit ​​section. The snap-fit ​​section is used to accommodate the first sliding roller in the initial state, and the sloped section is used to drive the locking swing arm to deflect when the sliding seat moves relative to the side bracket.

[0012] Preferably, a secondary protective baffle is also hinged to the sliding seat. A third guide groove is provided on the sliding seat, which extends along the length of the sliding seat. A fixed bracket is connected to the outer wall of the side support facing the third guide groove via a third elastic element. The fixed bracket can move relative to the side support along the extension direction of the third guide groove. A transmission pin is provided at the bottom of the fixed bracket extending into the third guide groove. A roller is rotatably connected to the transmission pin, and the roller rolls in cooperation with the third guide groove. A connecting rod is hinged between the transmission pin and the secondary protective baffle.

[0013] Preferably, the method of using the storage device for luncheon meat canning includes the following steps: S1: Release the can tray from the side of the placement plate, and the can tray will accelerate down the slope under the action of gravity; S2: The can tray first contacts the buffer abutment plate, pushing the sliding seat to compress the first elastic element and perform main buffering and energy absorption; S3: When the sliding seat moves, it drives the side bracket and locking swing arm to move synchronously. The second sliding roller moves along the straight section of the second guide groove to the arc-shaped locking section and is locked, and the side bracket stops moving. S4: The sliding seat continues to move, generating relative displacement with the side support, stretching the second elastic element. At the same time, the first sliding roller slides from the snap-fit ​​section of the first guide groove into the inclined section, forcing the locking swing arm to deflect, driving the second sliding roller to squeeze the friction pad and the limiting ball in the arc-shaped locking section, generating progressive damping, so that the pallet speed gradually decreases and stops smoothly. S5: While the sliding seat moves relative to the side support, the secondary protective baffle is driven by the linkage through the relative movement of the third guide groove and the transmission pin to unfold from the retracted state and span over the placement plate to block the subsequent misplaced can trays. S6: After the can tray is removed, the sliding seat moves back under the action of the first elastic element's reset force, the second elastic element resets so that the sliding seat and the side support move closer together again, the locking swing arm resets, and the secondary protective baffle retracts and resets.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: In this invention, when the sliding seat and the side support are relatively displaced, the locking swing arm deflects and squeezes the friction pad. The friction pad transmits the pressure to the limiting ball. The limiting ball is subjected to a gradually increasing radial constraint force in the V-shaped insert groove, thereby generating a damping force that increases with the increase of displacement. The progressive damping causes the can pallet to gradually reduce its speed in the last segment of its stroke before landing on the support, and finally achieve a smooth stop. Since the kinetic energy of the pallet has been fully consumed before it stops, even if the elastic potential energy stored in the first elastic element is released, it cannot drive the pallet to produce obvious reciprocating swaying. This completely solves the problem of repeated swaying of the pallet after impact in the prior art and improves the stability of pallet positioning.

[0015] In this invention, when the first can tray slides down and comes into contact with the buffer anti-collision component, the relative displacement between the sliding seat and the side support causes the relative movement to automatically drive the secondary protective baffle from the retracted state to the unfolded state via the linkage, spanning the space above the placement plate. If the operator releases the second tray before the first tray has been removed, the second tray will slide down to the secondary protective baffle and be blocked. The impact energy will be absorbed and buffered by the compression of the third elastic element via the linkage, thereby effectively avoiding direct collision between the two trays and preventing damage to the cans or tray tipping over.

[0016] In this invention, the reset force of the first elastic element is greater than that of the second elastic element, ensuring that the sliding seat can be reset first after the first tray is removed, thereby driving the side support and secondary protective baffle to return to the initial state in an orderly manner. Under the reverse drive of the inclined section of the first guide groove, the locking swing arm, in conjunction with the preload of the torsion spring, allows the second sliding roller to smoothly exit from the arc-shaped locking section and return along the straight groove section, realizing the automatic reset of the entire buffer anti-collision assembly. This enables the storage device to continuously and stably perform multiple operations without manual adjustment or maintenance, thus improving the automation level of the production line.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example Please see Figures 1 to 12 The present invention provides a technical solution: a storage device for luncheon meat can production, including a buffer and anti-collision component 2 for the storage of can pallets 5, which is suitable for multi-layer inclined shelves 1 and solves the problem of excessive impact at the end of the pallet's descent and repeated shaking after landing in the prior art. The multi-layer inclined shelving 1 includes a placement rack 11 located on the ground. The placement rack 11 is configured as a multi-layer structure in the vertical direction. Each layer is equipped with an inclined placement plate 12. A support bracket 13 for supporting canned food trays 5 is fixed to one outer wall of the placement rack 11. The high side of the placement plate 12 faces the operator, and the low side is adjacent to the support bracket 13, so that the canned food trays 5 can slide freely from the high side to the low side by gravity. A lifting frame 14 driven by a screw slide is provided on the support bracket 13 to lift the canned food trays 5 to the corresponding layer height. The buffer anti-collision component 2 is integrated on the side wall of the placement rack 11 and is located at the low end of the inclined placement plate 12. Two sets of buffer anti-collision components 2 are symmetrically arranged on both sides of each layer of placement plate 12. The two sets of buffer anti-collision components 2 are mirror-distributed with the longitudinal central axis of the placement plate 12 as a reference. Taking one set as an example.

[0021] Specifically, the buffer anti-collision assembly 2 includes a support seat 21 fixedly mounted on the side wall of the placement rack 11, a sliding seat 22 slidably connected to the support seat 21, the sliding seat 22 being able to reciprocate along the length of the support seat 21, a first elastic element 23 being provided between the sliding seat 22 and the support seat 21, one end of the first elastic element 23 abutting against the sliding seat 22 and the other end abutting against the support seat 21, for being compressed to absorb energy when the sliding seat 22 is impacted, and a buffer abutting plate 24 is provided extending from the sliding seat 22 toward the placement plate 12, the buffer abutting plate 24 being used to directly contact the sliding can tray 5; When the first can tray 5 is released from the high side of the placement plate 12, it accelerates down under the action of gravity. The can tray 5 first contacts the buffer abutment plate 24, pushes the sliding seat 22 to slide along the support seat 21, and compresses the first elastic element 23. During this process, the first elastic element 23 converts the kinetic energy of the can tray 5 into elastic potential energy through elastic deformation, thereby achieving the main buffer against impact energy.

[0022] In this embodiment, a side support 3 is slidably connected to the outer wall of the sliding seat 22. The side support 3 can move relative to the sliding seat 22 along its length direction. A second elastic element 31 is provided between the sliding seat 22 and the side support 3. The second elastic element 31 keeps the sliding seat 22 and the side support 3 close to each other in the initial state. A limiting baffle 32 is fixedly installed on the support base 21. The limiting baffle 32 is located on the moving path of the buffer abutment plate 24 after being pressed. A second guide groove 321 is provided on the limiting baffle 32. The second guide groove 321 includes a straight groove section 3211 extending along the moving direction and an arc-shaped locking section 3212 located at the end of the straight groove section 3211. A plurality of limiting balls 322 are embedded in the arc-shaped locking section 3212. A V-shaped opening is provided on the limiting baffle 32 for the fitting groove 323. Each limiting ball 322 is floatingly disposed in the fitting groove 323 by an elastic sheet. A friction pad 324 is covered on the top of the limiting ball 322. A locking swing arm 33 is rotatably connected to the side bracket 3 via a rotating shaft. A torsion spring is sleeved on the rotating shaft. The torsion spring causes the locking swing arm 33 to always apply a preload towards the sliding seat 22. A first sliding roller 34 and a second sliding roller 35 are arranged opposite to each other on the locking swing arm 33. The first sliding roller 34 is located on the side closer to the sliding seat 22, and the second sliding roller 35 is located on the side closer to the limiting baffle 32. The sliding seat 22 is provided with a first guide groove 221. The first guide groove 221 includes a snap-fit ​​section 2211 and a sloped section 2212 that is smoothly connected to the snap-fit ​​section 2211. The snap-fit ​​section 2211 is used to accommodate the first sliding roller 34 in the initial state, and the sloped section 2212 is used to drive the locking swing arm 33 to deflect when the sliding seat 22 moves relative to the side bracket 3. In the initial state, the sliding seat 22 and the side support 3 approach each other under the action of the second elastic element 31. The locking arm 33 faces the sliding seat 22 under the action of the torsion spring. Its first sliding roller 34 is located in the snap-fit ​​section 2211 of the first guide groove 221. When the can tray 5 slides down and contacts the sliding seat 22, the sliding seat 22 initially slides, driving the side support 3 and the locking arm 33 to move synchronously. The second sliding roller 35 on the locking arm 33 enters the straight groove section 3211 of the second guide groove 321 on the limiting baffle 32 and moves along the straight groove section 3211. When the second sliding roller 35 reaches the arc-shaped locking section 3212, it is locked by the arc-shaped locking section 3212, and the side support 3 stops moving. At this time, the sliding seat 22 continues to move forward under the continuous gravity of the tray, and relative displacement occurs with the stopped side support 3, thereby stretching the second elastic element 31. The first sliding roller 34 on the locking swing arm 33 slides from the snap-fit ​​section 2211 of the first guide groove 221 into the inclined section 2212, and is forced to deflect against the torsion of the torsion spring by the downward pressure of the inclined section 2212. The deflection of the locking arm 33 causes the second sliding roller 35 to press the friction pad 324 within the arc-shaped locking section 3212. After being pressed, the friction pad 324 transmits the pressure to the lower limiting ball 322, forcing the limiting ball 322 to further embed into the V-shaped insert groove 323. Since the cross-section of the V-shaped insert groove 323 is V-shaped, the limiting ball 322 is subjected to a gradually increasing radial constraint force during the embedding process. The constraint force is fed back to the second sliding roller 35 through the friction pad 324, forming a progressive damping force. The progressive damping causes the speed of the first can tray 5 to gradually decrease in the last segment of its stroke before falling onto the support bracket 13, eventually achieving a smooth stop, thereby eliminating the reciprocating swaying that may be caused by the rebound of the first elastic element 23.

[0023] In this embodiment, a secondary protective baffle 4 is also hinged to the sliding seat 22, and a third guide groove 222 is provided on the sliding seat 22, which extends along the length direction of the sliding seat 22. A fixed bracket 42 is connected to the outer wall of the side bracket 3 facing the third guide groove 222 via a third elastic element 41. The fixed bracket 42 can move relative to the side bracket 3 along the extension direction of the third guide groove 222. A transmission pin 43 is provided at the bottom of the fixed bracket 42 extending into the third guide groove 222. A roller 44 is rotatably connected to the transmission pin 43. The roller 44 rolls with the third guide groove 222. A connecting rod 45 is hinged between the transmission pin 43 and the secondary protective baffle 4. The connecting rod 45 is used to convert the relative motion between the transmission pin 43 and the third guide groove 222 into the swing motion of the secondary protective baffle 4. In the initial state, the secondary protective baffle 4 is in a retracted state and is attached to the outside of the sliding seat 22. It does not affect the path of the can tray 5 during the downward movement. When the first can tray 5 contacts the sliding seat 22, the sliding seat 22 and the side support 3 are relatively displaced. Since the side support 3 is stationary while the sliding seat 22 moves, the fixed support 42 fixed on the side support 3 remains stationary. The third guide groove 222, which moves with the sliding seat 22, moves relative to the fixed support 42. The transmission pin 43 slides relative to the roller 44 in the third guide groove 222. The relative motion is converted into the rotational motion of the secondary protective baffle 4 through the connecting rod 45, thereby driving the secondary protective baffle 4 to change from the retracted state to the unfolded state. The secondary protective baffle 4, in its unfolded state, spans the space above the placement plate 12, forming a physical barrier. If the operator mistakenly places the second can tray 5 on the high side of the placement plate 12, the second can tray 5 will be blocked when it slides down to the secondary protective baffle 4 and come into contact with it. After being compressed, the secondary protective baffle 4 pushes the fixed bracket 42 through the connecting rod 45. The fixed bracket 42 compresses the third elastic element 41, absorbing and buffering the impact energy of the second can tray 5, thereby effectively avoiding direct collision between the two trays. When the first can tray 5 is removed from the support bracket 13, the sliding seat 22 begins to move back under the restoring force of the first elastic element 23. Since the restoring force of the first elastic element 23 is greater than the restoring force of the second elastic element 31, the relative displacement between the sliding seat 22 and the side support 3 gradually decreases, the stretched second elastic element 31 recovers, and the two come together again. Under the reverse drive of the inclined section 2212 of the first guide groove 221, the locking arm 33 slides back to the snap-fit ​​section 2211 along the inclined section 2212. At the same time, the locking arm 33 recovers its initial deflection angle under the action of the torsion spring. The second sliding roller 35 exits from the arc-shaped locking section 3212 and returns to the initial position along the straight groove section 3211. The relative reset movement of the sliding seat 22 and the side bracket 3 simultaneously drives the third guide groove 222 to move in the opposite direction relative to the transmission pin 43. The reverse movement drives the secondary protective baffle 4 to retract from the unfolded state back to the initial position through the connecting rod 45, and the entire buffer anti-collision assembly 2 is fully reset, ready for the next operation.

[0024] In this embodiment, the first elastic element 23, the second elastic element 31 and the third elastic element 41 are all compression coil springs.

[0025] In this embodiment, the tilt angle of the placement plate 12 is preferably 8°~12°.

[0026] In this embodiment, the friction pad 324 is made of polytetrafluoroethylene or wear-resistant rubber material.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention.

S6: After the can tray (5) is removed, the sliding seat (22) moves back under the reset force of the first elastic element (23), the second elastic element (31) resets so that the sliding seat (22) and the side support (3) come together again, the locking arm (33) resets, and the secondary protective baffle (4) retracts and resets.
