Description

Technical Field

[0001] This invention relates to the field of automatic palletizing technology for industrial ice making, specifically to an automatic palletizing device for industrial ice making machines. Background Technology

[0002] As a large-scale refrigeration equipment, industrial ice makers can continuously and on a large scale produce regular block ice. After the ice blocks are produced, they usually need to be stacked neatly through a palletizing operation to form a stable and uniform transport unit, thereby ensuring the utilization efficiency of storage space such as cold storage and facilitating the subsequent bulk logistics transportation of ice blocks.

[0003] In existing automated ice palletizing operations, hoisting equipment or industrial robotic arms are typically used to control gripping structures to grasp and transport shaped ice blocks. The gripping structure is generally a single claw that can only hold a single ice block, but it can also be an enlarged single claw that covers multiple ice blocks, or a combination structure of multiple claws connected in parallel to grasp multiple ice blocks at the same time, thereby completing the automated palletizing operation of the entire ice block in an efficient and orderly manner.

[0004] However, traditional automated ice palletizing methods have the following problems: 1. In existing technologies, because the surface of ice is smooth and often covered with a layer of water film, the grippers often need to apply a large clamping force to overcome the risk of slippage and ensure gripping stability. This can easily lead to pressure damage or cracking of the ice surface. Surface damage not only reduces the integrity and quality of the ice but may also further weaken the effective contact and friction between the grippers and the ice surface, creating a vicious cycle of decreased gripping stability, ultimately affecting the reliability and efficiency of ice palletizing operations; 2. In existing technologies, the gripper structure needs to frequently collide with the hard surface of the ice. Due to the hard texture and low temperature of ice, the gripping components that directly collide with it are prone to significant wear. This not only increases the replacement frequency and maintenance costs but also affects the palletizing operation due to frequent downtime for maintenance. 1. The lack of continuity increases the overall operation steps, which adversely affects the overall production and processing efficiency and economy. 2. In the existing technology, since the ice blocks produced by existing ice makers are not completely uniform, the enlarged single claw, due to its rigid integrated structure, is difficult to adapt to the slight differences in size and shape between ice blocks, which easily leads to uneven distribution of clamping force. Some ice blocks may be crushed by pressure while others are not firmly grasped. Although the multi-claw parallel structure improves the gripping stability of individual ice blocks to a certain extent through independent control units, its complex mechanical design, additional pneumatic circuits and control systems significantly increase equipment costs and maintenance difficulty. More importantly, both of the above batch gripping methods lack the ability to quickly adjust to changes in the size of ice blocks of different specifications, resulting in insufficient overall flexibility and limiting their application in multi-model ice block production scenarios. Summary of the Invention

[0015] Preferably, the lifting and gripping part includes a slide plate slidably disposed inside the U-shaped limiting frame.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The present invention, through the cooperation of the adjustment mechanism, the limiting mechanism and the gripping mechanism, can achieve stable limiting and lifting gripping of ice blocks, replacing the direct gripping of traditional grippers, thereby effectively avoiding direct compression of the ice block surface and fundamentally eliminating ice damage caused by excessive gripping force. This not only significantly improves the reliability of gripping operations, but also reduces hard collisions between the gripping structure and the ice block surface, thereby greatly reducing the wear of the gripping structure itself, extending the service life of the equipment, and ensuring the continuity of palletizing operations and the overall economic benefits of production and processing.

[0019] 2. This invention, through the coordination of the adjustment mechanism, the limiting mechanism, and the gripping mechanism, can achieve simultaneous gripping of multiple ice blocks with fewer drive units. This not only significantly reduces equipment complexity and cost while ensuring efficient palletizing, but also has good size adaptability. It will not affect the gripping stability due to slight differences in size or shape between ice blocks, thereby effectively avoiding ice breakage caused by local stress concentration. At the same time, the gripping structure can be quickly adjusted according to different specifications of ice blocks, which significantly improves the flexibility and applicability of the equipment under different production needs.

Detailed Implementation

[0032] 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.

[0033] Please see Figure 1 An automatic palletizing device for an industrial ice maker includes an L-shaped lifting frame 2 for grabbing and palletizing ice blocks 1. The L-shaped lifting frame 2 is connected to an external lifting device or an industrial robotic arm. An adjustment mechanism 3 is provided on the lower side of the L-shaped lifting frame 2. A limit mechanism 4 is provided on the adjustment mechanism 3. A grabbing mechanism 5 is provided on both the adjustment mechanism 3 and the limit mechanism 4.

[0034] Please see Figure 1 The adjustment mechanism 3 includes a deflection adjustment part 31 for driving the ice block 1 to deflect and adjust. The deflection adjustment part 31 is provided with a deflection support part 32 for supporting the deflection adjustment. The deflection adjustment part 31 and the deflection support part 32 are jointly provided with a spacing adjustment part 33 for lateral adjustment to adapt to grabbing ice blocks 1 of different sizes.

[0035] Please see Figure 1 and Figure 2The deflection adjustment unit 31 includes a hydraulic cylinder 311 rotatably mounted on the lower side of the horizontal section of the L-shaped hoisting frame 2 via a support. A U-shaped plate 312 is fixedly mounted on the telescopic end of the hydraulic cylinder 311. A U-shaped deflection frame 313 is symmetrically mounted on the lower side of the horizontal section of the L-shaped hoisting frame 2, located on the lower side of the U-shaped plate 312. Baffles 314 are symmetrically fixedly mounted on the lower side of the U-shaped deflection frame 313. The upper side of the left end of the horizontal section of the U-shaped deflection frame 313 is hinged to the U-shaped plate 312 via a support.

[0036] Please see Figure 1 , Figure 2 and Figure 3 The deflection support 32 includes a mounting plate 321 that is symmetrically fixed between the U-shaped deflection frames 313 and located above the baffle 314. A connecting plate 322 is symmetrically fixed on the lower side of the right baffle 314. A deflection support column 323 that is hinged to the lower end of the vertical section of the L-shaped hoisting frame 2 is fixed on the lower side of the connecting plate 322.

[0037] When ice block 1 needs to be deflected, the L-shaped lifting frame 2 is first moved downwards by external hoisting equipment or an industrial robotic arm. The U-shaped deflection frame 313 then moves the limiting mechanism 4 downwards synchronously, limiting the ice block 1 in all directions until the platform (not shown in the figure) where the ice block 1 is placed can stably support the deflection support column 323. Then, the hydraulic cylinder 311 pulls the support second and the left end of the horizontal section of the U-shaped deflection frame 313 to the upper right via the U-shaped plate 312, thereby causing all the ice blocks 1 limited by the U-shaped deflection frame 313 and the limiting mechanism 4 to deflect synchronously to the right by a certain angle (e.g., Figure 10 As shown in the figure, since the overall deflection angle of ice block 1 is small and the deflection duration is short, and the limiting mechanism 4 can provide certain support for ice block 1 and the ice block 1 itself is relatively hard, the temporary deflection state will not cause damage to the lower right corner of ice block 1, which bears part of its own weight.

[0038] Please see Figure 1 and Figure 3 The spacing adjustment part 33 includes a slide rod 331 fixedly installed inside the U-shaped deflection frame 313 and extending left and right. A threaded rod 332 located between the front and rear symmetrical slide rods 331 is fixedly installed between the left and right symmetrical mounting plates 321. Multiple docking plates 333 are evenly arranged on the left and right sides below the slide rods 331. A slide seat 334 that is slidably connected to the corresponding slide rod 331 is fixedly installed on the upper side of the docking plate 333. A threaded sleeve 335 that is threadedly connected to the threaded rod 332 is rotatably installed on the upper side of the docking plate 333 through the support. A knob 336 is fixedly installed on the left side of the threaded sleeve 335.

[0039] By rotating knob 336, the threaded sleeve 335 is driven to rotate synchronously, so that the threaded sleeve 335 drives the docking plate 333 and the slide block 334 to move left and right along the slide rod 331 through the screw transmission with the threaded rod 332, thereby adjusting the distance between adjacent docking plates 333 and the distance between the rightmost docking plate 333 and the right vertical section of the U-shaped deflection frame 313.

[0040] Please see Figure 1 and Figure 4 The limiting mechanism 4 includes a width limiting docking part 41 disposed on the lower side of the spacing adjustment part 33 and used for left and right limiting along the width direction of the ice block 1, and a length limiting docking part 42 disposed on the width limiting docking part 41 for front and rear limiting along the length direction of the ice block 1.

[0041] Please see Figure 4 , Figure 5 and Figure 6 The width-limiting docking part 41 includes a fixing plate 411 fixedly disposed on the lower side of the docking plate 333. Guide rods 412 are symmetrically fixedly disposed on the lower side of the fixing plate 411. U-shaped slides 413 that move up and down and have upward openings are slidably disposed on the guide rods 412.

[0042] When lateral positioning along the width of ice block 1 is required, firstly, the threaded sleeve 335 is rotated to move the docking plate 333 left and right for adjustment. The fixed plate 411 then moves the guide rod 412 and the U-shaped carriage 413 on the guide rod 412 synchronously for adjustment until the spacing between adjacent U-shaped carriages 413 and the spacing between the rightmost U-shaped carriage 413 and the right vertical section of the U-shaped deflector 313 are equal and can stably position the ice blocks 1 left and right along the width of ice block 1. Then, external hoisting equipment or an industrial robotic arm is used to move the U-shaped deflector 313 and U-shaped carriages 413 downwards synchronously, thereby using each U-shaped carriage 413 and the right vertical section of the U-shaped deflector 313 to stably position the spaced ice blocks 1 left and right (e.g., ...). Figure 9 (As shown).

[0043] Please see Figure 4 , Figure 5 and Figure 6 The length limiting docking part 42 includes a bidirectional screw 421 that is rotatably mounted on the vertical section of the U-shaped slide 413. A knob 422 is fixedly mounted on the rear side of the bidirectional screw 421. An adjustment groove 423 is provided on the upper side of the horizontal section of the U-shaped slide 413. An L-shaped limiting plate 424 is symmetrically slidably mounted on the horizontal section of the U-shaped slide 413. A threaded seat 425 that is slidably connected to the adjustment groove 423 and threadedly connected to the bidirectional screw 421 is fixedly mounted on the upper side of the opposite end of the L-shaped limiting plate 424.

[0044] When the ice block 1 needs to be limited forward and backward along its length, rotating knob 422 drives the bidirectional screw 421 to rotate synchronously. The bidirectional screw 421 then drives the L-shaped limiting plate 424 to move in opposite directions or towards each other through the screw drive with the threaded seat 425, until the horizontal plate spacing at the opposite end of the L-shaped limiting plate 424 can stably limit the ice block 1 forward and backward. Then, the U-shaped deflection frame 313 and the U-shaped slide 413 are moved downward synchronously by external hoisting equipment or industrial robotic arm. The L-shaped limiting plate 424 moves downward synchronously, thereby stably limiting the ice block 1 forward and backward through the horizontal plates on the symmetrical L-shaped limiting plates 424 (e.g., Figure 1 (As shown).

[0045] When limiting the ice block 1 to the left or right or front or back, it is not necessary to make the U-shaped carriage 413 and the L-shaped limiting plate 424 fit tightly with the ice block 1. It is only necessary to stabilize the ice block 1 so that the ice block 1 will not shake significantly during deflection and grabbing and stacking.

[0046] Please see Figure 1 and Figure 4 The gripping mechanism 5 includes a sliding limiting part 51 disposed on the lower side of the length limiting docking part 42, a lifting gripping part 52 disposed on the sliding limiting part 51 for lifting and gripping ice blocks 1, an adjustment driving part 53 disposed on the deflection adjustment part 31, and a transmission adjustment part 54 disposed on the adjustment driving part 53. The adjustment driving part 53 cooperates with the transmission adjustment part 54 to drive the lifting gripping part 52 to grip ice blocks 1 in batches.

[0047] Please see Figure 4 , Figure 5 and Figure 7 The sliding limiting part 51 includes connecting columns 511 symmetrically fixedly arranged on the lower side of the U-shaped slide 413. A loop-shaped limiting frame 512 is fixedly arranged on the lower side of the connecting columns 511. A straight groove 513 extending forward and backward is opened on the upper side of the loop-shaped limiting frame 512, and a straight groove 514 extending forward and backward is opened on the lower side of the loop-shaped limiting frame 512.

[0048] Please see Figure 4 , Figure 7 and Figure 8 The lifting and gripping part 52 includes a slide plate 521 slidably disposed inside the U-shaped limiting frame 512. A connecting shaft 522 that is slidably connected to the corresponding straight groove 513 is fixedly disposed on the upper side of the rear end of the slide plate 521. A driven block 523 is fixedly disposed on the upper side of the connecting shaft 522. Multiple connecting shafts 524 that are slidably connected to the corresponding straight groove 514 are evenly fixedly disposed on the lower side of the slide plate 521. An L-shaped connecting platform 525 is fixedly disposed on the lower side of the connecting shafts 524. A wedge-shaped support plate 526 is fixedly disposed on the right side of the L-shaped connecting platform 525.

[0049] When batch grabbing of ice blocks 1, the U-shaped carriage 413 and U-shaped deflection frame 313 are first used by external hoisting equipment or industrial robotic arm to limit the left and right movement of ice blocks 1, and at the same time, the L-shaped limiting plate 424 limits the front and rear movement of ice blocks 1 (e.g., Figure 9 As shown, the platform on which ice block 1 is placed provides stable support to the underside of the deflection support column 323, the L-shaped connecting platform 525, and the wedge-shaped support plate 526. Then, the hydraulic cylinder 311 drives the U-shaped deflection frame 313 to deflect to the right at a certain angle. The U-shaped slide 413 and the L-shaped limiting plate 424 then drive the ice block 1 to deflect synchronously. During the deflection process, the U-shaped slide 413 will slide relative to the corresponding guide rod 412, and the underside of the wedge-shaped support plate 526 will always be in contact with the platform. Touch until the deflected wedge plate 526 can be stably inserted into the wedge-shaped space under the corresponding deflected ice block 1. At this time, the driven block 523 and the connecting shaft 1 522 can be driven to move forward along the straight groove 1 513 by adjusting the drive unit 53 in conjunction with the transmission adjustment unit 54. The slide plate 521 then drives the L-shaped connecting platform 525 and the wedge plate 526 to move forward along the straight groove 2 514 to the foremost position through the connecting shaft 2 524. The wedge plate 526 then moves to the underside of the corresponding deflected ice block 1 (e.g., Figure 10 As shown), lubricating oil can be applied to the lower side of the inclined surface of the wedge-shaped support plate 526 or ball bearings can be installed to reduce the frictional resistance during the movement of the wedge-shaped support plate 526. Then, the hydraulic cylinder 311 drives the U-shaped deflecting frame 313 to deflect and reset to the left, and the deflected ice block 1 resets synchronously. The lower surface of the ice block 1 then comes into contact with the upper surface of the wedge-shaped support plate 526. Thus, the U-shaped slide 413, the U-shaped deflecting frame 313, the L-shaped limiting plate 424, and the wedge-shaped support plate 526 can synchronously limit and lift each ice block 1 (e.g., Figure 11 (As shown).

[0050] When stacking the grasped ice block 1, the U-shaped deflection frame 313 is first moved upward a certain distance by external hoisting equipment or an industrial robotic arm. The U-shaped carriage 413 and the wedge-shaped support plate 526 then slide relative to each other along the corresponding guide rod 412 until the guide rod 412 can drive the U-shaped carriage 413 and the wedge-shaped support plate 526 to move upward synchronously. At this time, the grasped ice block 1 moves upward synchronously. Then, the grasped ice block 1 is moved to the stacking position by external hoisting equipment or an industrial robotic arm, and the U-shaped deflection frame 313 is moved downward until the deflection support column 323. Once stably supported, the U-shaped deflector 313 and the ice block 1 can be simultaneously deflected to the right at a certain angle until the lower surface of the ice block 1 is no longer tightly attached to the upper surface of the wedge-shaped support plate 526. At this point, the wedge-shaped support plate 526 can be moved backward to reset by adjusting the drive unit 53 in conjunction with the transmission adjustment unit 54. Then, the U-shaped deflector 313 is deflected to the left to reset to the initial state. The ice block 1 is deflected and reset and stacked to the required position. Finally, the U-shaped deflector 313 and the U-shaped slide 413 can be moved upward to reset by external hoisting equipment or industrial robotic arm until they are completely separated from the ice block 1.

[0051] The above-described operation method enables stable positioning and lifting gripping of ice block 1, replacing the direct gripping of traditional grippers. This effectively avoids direct compression of the surface of ice block 1 and fundamentally eliminates ice damage caused by excessive gripping force. It not only significantly improves the reliability of gripping operations but also reduces hard collisions between the gripping structure and the surface of ice block 1, thereby greatly reducing wear on the gripping structure itself, extending the service life of the equipment, and ensuring the continuity of palletizing operations and the overall economic benefits of production and processing.

[0052] Please see Figure 1 and Figure 8 The adjustment drive unit 53 includes a multi-section cylinder 531 fixedly mounted on the opposite side of the baffle 314 via a support four. The telescopic end of the multi-section cylinder 531 is fixedly mounted with an L-shaped connecting plate 532 that moves back and forth. A slide rail 533 is fixedly mounted between the left and right symmetrical L-shaped connecting plates 532. Multiple sliders 534 are evenly slidably mounted on the lower side of the slide rail 533. Each slider 534 corresponds to a docking plate 333.

[0053] Please see Figure 1 , Figure 7 and Figure 8 The transmission adjustment unit 54 includes a transmission frame 541 fixedly disposed on the lower side of the slider 534. A straight groove 542 extending through the front and back and extending vertically is provided on the transmission frame 541. A sliding shaft 543 that moves vertically is slidably disposed on the straight groove 542. A transmission rod 544 is fixedly disposed together between the sliding shaft 543 and the corresponding driven block 523.

[0054] When the U-shaped deflector 313 deflects the ice block 1 to the desired angle, the multi-section cylinder 531 on the U-shaped deflector 313 drives the slide rail 533 and the slider 534 on the slide rail 533 to deflect synchronously via the L-shaped connecting plate 532. At this time, the U-shaped slide 413 drives the driven block 523 to slide relative to the corresponding guide rod 412. The driven block 523 then drives the corresponding transmission rod 544 and the slide shaft 543 to move synchronously along the straight groove 3 542 until the wedge-shaped support plate 526 is located under the deflected ice block 1 and the upper surface of the wedge-shaped support plate 526 is not in close contact with the lower surface of the ice block 1 (e.g., Figure 10 As shown), at this time, the multi-section cylinder 531 can drive the transmission frame 541 and transmission rod 544 to move back and forth through the slide rail 533 and slider 534, thereby driving the wedge plate 526 to move forward to support the ice block 1 or move backward to release the limiting grip on the ice block 1.

[0055] When the threaded sleeve 335 drives the docking plate 333 and the U-shaped slide 413 to move left and right for adjustment, the U-shaped slide 413 then drives the corresponding transmission frame 541 and slider 534 to move left and right synchronously along the slide rail 533 through the transmission rod 544 and the slide shaft 543.

[0056] The above-described operation method enables the simultaneous gripping of multiple ice blocks 1 with fewer drive units. This not only significantly reduces equipment complexity and cost while ensuring efficient palletizing, but also has good size adaptability. It does not affect the gripping stability due to slight differences in size or shape between ice blocks 1, thus effectively avoiding ice breakage caused by local stress concentration. At the same time, the gripping structure can be quickly adjusted according to different specifications of ice blocks 1, which significantly improves the flexibility and applicability of the equipment under different production needs.
