Description

Technical Field

[0001] The invention relates to the technical field of cargo stackers, in particular to a stacker capable of self-adapting cargo sizes. Background Art

[0002] A stacker is a special transport device that uses a fork or a string rod as a picking device to grab, carry and stack unit goods in warehouses, workshops, etc., or to pick up and place unit goods from high-rise shelves. It is a kind of warehousing equipment and is widely used in actual life. Among them, the more common ones are aisle stackers, high-bay stackers, etc. When the existing stackers are in use, they mainly use forks to take down or stack goods, but this structure requires a pad under the goods, or each item is placed separately on a layer. This is also the current mainstream way of placing goods. The disadvantage is that it takes up a lot of space. Therefore, we have launched a stacker that can adapt to the size of the goods.

[0003] The existing patent (publication number: CN115092591A) discloses an aisle stacker with adaptive cargo size, including a stacker outer frame, a loading assembly, a first gear, a second gear, two lifting mechanisms and two measuring mechanisms, the lifting mechanism including a first fork telescopic rod and a second fork telescopic rod, the first fork telescopic rod is slidably arranged on the first slide, the measuring mechanism includes a first ranging telescopic rod, a second ranging telescopic rod, a second tooth plate, a third tooth plate, a fourth tooth plate, a first spring block, a rack and a sixth gear, the first ranging telescopic rod is slidably arranged on the second slide, the disengagement mechanism is used to disengage the first gear and the second gear, and the driving mechanism is used to drive the lifting mechanism to move horizontally. The invention provides an aisle stacker with adaptive cargo size to solve the problems that the size of the existing stacker cannot be adjusted, the loading surface is too small when transporting large cargo, and the elongation of the fork cannot be adjusted according to the size of the cargo. The above technology has the following problems: 1. When the existing stacker is in use, the fork is inserted into the bottom of the goods, the goods are lifted up and transported, so as to complete the unloading or stacking. However, the goods are separated by a pad, and the bottom of the pad is a hollow structure so that there is a gap between the pad and the next layer of goods, so that the fork can be inserted without damaging the goods, but this stacking method requires a large space; 2. When the existing stacker is removing or stacking the goods, the goods need to be limited and fixed, otherwise the goods will slide off the stacker due to inertia during transportation, which is very dangerous. However, the sizes of the goods are different. When faced with goods of different sizes, it is difficult to limit and fix goods of various sizes well, and the adaptability is poor.

[0017] In the present invention, the goods are clamped on the left and right by the clamping plates arranged on both sides, and the goods are automatically lifted upward after clamping to separate the goods from the goods on the next layer. After separation, the pad is inserted into the bottom of the lifted goods to prevent the goods between the two clamping plates from falling during transportation.

[0018] In the present invention, goods of different sizes can be clamped by adopting a two-side clamping method. The forks of a conventional bottom fork stacker are fixed at a distance and are unstable when inserting and taking large-sized goods.

[0019] In the present invention, a pad with a trapezoidal cross-section is inserted into the bottom of the cargo to support the bottom of the lifted cargo. When unloading, the clamping plates on both sides of the cargo move away from each other to release the clamping of the cargo. At this time, the two pads also move away from each other. Under the action of the inclined surface of the pad, the cargo will gradually fall and finally land at the desired position, and the cargo will not be damaged by sudden falling.

[0020] In the present invention, the goods are clamped and lifted by the stacking assembly, and the top surface of the goods will enter the middle of the limiting assembly while the goods are lifted. In addition, during the lifting process, the vertical rack in the stacking assembly will also drive the long gear to rotate, and the long gear will drive the spiral cam to drive the limiting assembly to limit the goods. The airbags in the limiting assembly are connected by a connecting hose. This structure will cause the gas in the airbag in contact with the goods to be squeezed into the inside of the airbag that has not yet contacted the goods, and the airbag that has not contacted the goods will also contact the goods after expansion, thereby limiting the goods in all directions to prevent the goods from sliding due to inertia during movement.

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technical personnel in this field without creative work are within the scope of protection of the present invention.

[0034] See also Figures 1 to 11 The present invention provides a technical solution: a stacker with adaptive cargo size, comprising a mounting bracket 1, a driving mechanism 2 is fixedly connected to the middle of one side of the mounting bracket 1, a mounting frame 3 is provided on one side of the driving mechanism 2, a slide groove 4 is provided on the inner wall of the mounting frame 3, a stacking component 5 is provided in the middle of the mounting frame 3, a limit component 6 is provided above the stacking component 5, and a transmission component 7 is movably connected to one side of the limit component 6.

[0035] In this embodiment, Figure 1 , Figure 3 and Figure 4As shown, the stacking assembly 5 includes a hydraulic rod 501 and a limit rod 502 fixedly connected to the inner walls of both sides of the installation frame 3, the output end of the hydraulic rod 501 is fixedly connected to a slide plate 503, the middle part of the slide plate 503 is provided with an inclined groove 504, the bottom of one side of the slide plate 503 is fixedly connected to a pad 505, the side of the slide plate 503 away from the pad 505 is attached to a slide plate 2 506, the middle part of the slide plate 2 506 is provided with an L-shaped groove 507, the middle part of the L-shaped groove 507 and the middle part of the inclined groove 504 are penetrated by a movable rod 508, the end of the movable rod 508 away from the installation frame 3 is fixedly connected to a clamping plate 509, one side of the clamping plate 509 is provided with an anti-slip layer 5010, and the end of the movable rod 508 away from the clamping plate 509 is fixedly connected to a vertical rack 5011. A connecting slider 5012 is fixedly connected to the bottom of one side of the slide plate 2 506, and a limit plate 5013 is fixedly connected to one side of the slide plate 2 506 near the middle of the installation frame 3, and a roller 1 5014 is rollingly connected to one side of the limit plate 5013; the driving mechanism 2 is composed of a vertical electric push rod and a horizontal electric push rod, which can drive the installation frame 3 to move vertically and front and back directions, and the L-shaped groove 507 is composed of a horizontal groove and a vertical groove. The slide plate 1 503 is pushed by the hydraulic rod 501 to approach the goods in the middle of the installation frame 3. At this time, the slide plate 1 503 cooperates with the inclined groove 504 to push the movable rod 508 to slide along the horizontal groove of the L-shaped groove 507, and when the movable rod 508 and the slide plate 1 503 move, the movable rod 508 can drive the clamping plate 50 9 moves, and the slide plate 1 503 drives the pad plate 505 to move synchronously. Since the L-shaped groove 507 is opened in the middle of the slide plate 2 506, when the movable rod 508 moves to the intersection of the horizontal groove and the vertical groove, the movable rod 508 will drive the slide plate 2 506 to move closer to the goods until the limiting plate 5013 on one side of the slide plate 2 506 fits with the goods. At this time, the roller 1 5014 on the limiting plate 5013 will contact the side of the goods, making it impossible for the slide plate 2 506 to continue to move. At this time, the anti-skid layer 5010 on one side of the clamping plate 509 will also fit with the side of the goods, and the anti-skid layer 5010 will exceed a part of the roller 1 5014. Therefore, the anti-skid layer 5010 is squeezed by the goods and the clamping plate 509 on both sides. 010 to clamp the cargo, after which the hydraulic rod 501 will continue to extend and push the slide plate 503 to continue to approach the cargo. At this time, under the squeezing of the inclined slot 504, the movable rod 508 will move upward along the vertical slot, so that the movable rod 508 drives the clamping plate 509 to move upward, thereby lifting the cargo upward. At this time, the bottom of the cargo is separated from the next layer of cargo. During the rising process of the clamping plate 509, the pad 505 also approaches the cargo with the slide plate 503, because the side of the pad 505 close to the clamping plate 509 is an inclined surface, and while the pad 505 moves toward the cargo, the clamping plate 509 moves upward to avoid the pad 505. Therefore, the clamping plate 509 will not interfere with the pad 505, and the pad 505 is inserted into the bottom of the clamped cargo.It plays a supporting role for the goods and prevents the goods from slipping from between the two clamping plates 509 during transportation, and the roller 1 5014 can reduce the friction between the goods and the limit plate 5013 when they are rising, so as to avoid excessive friction between the limit plate 5013 and the goods, which may cause the clamping plate 509 to be unable to lift the goods. This device is different from the traditional stacker. It uses the clamping method on both sides to lift the goods, and then uses the driving mechanism 2 to drive the stacking component 5 to move up and down and forward and backward to stack or remove the goods. The advantage of this structure is that there is no need to place a hollow plate at the bottom of the goods to facilitate the insertion of the rod to pick up and put the goods, which reduces the space required for stacking goods. , because the length of the slide 4 is consistent with the length of the rear plate of the mounting frame 3, the clamping plate 509 can push the second slide plate 506 to move as far as possible along the slide 4, increasing the size range of goods that the stacker can clamp, making it convenient to clamp goods of different sizes. The function of the limit rod 502 is that after the goods are released, if the movable rod 508 is stuck in the vertical slot and cannot be lowered, the second slide plate 506 is blocked by the limit rod 502, and the second slide plate 506 stops moving. At this time, the hydraulic rod 501 continues to contract and drives the first slide plate 503 to move, so that the inclined slot 504 in the middle of the first slide plate 503 squeezes the movable rod 508 into the horizontal slot, and then resets the movable rod 508. ,

[0036] In this embodiment, Figure 3 As shown, the pad 505 has a trapezoidal cross-section, and the inclined surface of the pad 505 is provided with a plurality of anti-skid strips, and the middle part of the top surface of the pad 505 is rollingly connected with two rollers 5015; the anti-skid strips can increase the friction between the pad 505 and the bottom of the cargo, and the rollers 5015 can reduce the friction between the cargo and the pad 505. When unloading is required, the two pads 505 are driven by the slide 1 503 and move away from the cargo at the same time, and the cargo will gradually descend along the inclined surface of the pad 505, so as to prevent the cargo from falling and being damaged directly after the clamping plate 509 releases its clamping. In addition, since the pads 505 on both sides are inclined toward the middle, the cargo will always remain in the middle position of the mounting frame 3 during unloading, and there will be no positional displacement.

[0037] In this embodiment, Figure 6 As shown, an annular groove 5016 is provided on the inner wall of the inclined groove 504, and a limit slider 5017 is slidably connected inside the annular groove 5016, and the limit slider 5017 is elliptical in shape; the elliptical rotating limit slider 5017 slides along the annular groove 5016, and the limit slider 5017 is fixedly connected to the movable rod 508, so the limit slider 5017 can limit the movable rod 508 to prevent the movable rod 508 from rotating around its own axis, causing the clamping plate 509 to tilt and fail to clamp the goods.

[0038] In this embodiment, Figure 3As shown, a plurality of wave grooves are provided on the side of the anti-slip layer 5010 away from the clamping plate 509; the wave grooves can increase the friction between the anti-slip layer 5010 and both sides of the goods, and the anti-slip layer 5010 is elastic. When the clamping plate 509 clamps the goods, the anti-slip layer 5010 will be squeezed, ensuring the clamping force applied by the clamping plate 509 to the goods, paving the way for the subsequent lifting of the goods.

[0039] In this embodiment, Figure 1 , Figure 2 and Figure 7-11 As shown, the limiting assembly 6 includes a mounting rod 601 fixedly connected to the inner wall of the mounting frame 3, the end of the mounting rod 601 away from the mounting frame 3 is fixedly connected to a fixing ring 602, the middle of the fixing ring 602 is rotatably connected to a rotating ring 603, the top surface of the rotating ring 603 is provided with a plurality of toggle pins 604, the outer ring of the rotating ring 603 is equiangularly distributed with a plurality of driven pins 605, the outer side of the fixing ring 602 is sleeved with a gear ring 606, the inner ring of the gear ring 606 is provided with a plurality of spiral grooves 6017, the gear ring 606 is rotatably connected to the fixing ring 602, the bottom of the fixing ring 602 is fixedly connected to a vertical connecting rod 607, and the bottom of one side of the vertical connecting rod 607 is fixedly connected to a T-block 6 08, T-block 608 is slidably connected inside the slide rail 609, and the slide rail 609 is fixedly connected to both sides of the horizontal rack 6010; the driven pin 605 will drive the rotating ring 603 to rotate under the drive of the transmission component 7, and the rotating ring 603 will drive the top surface of the toggle pin 604 to rotate when rotating, and the gap between the toggle pins 604 is adapted to the width of the ring gear 606. When the previous toggle pin 604 is about to disengage from the spiral groove 6017, the next toggle pin 604 will enter the next spiral groove 6017, thereby driving the ring gear 606 to rotate. When the ring gear 606 rotates, it will drive the horizontal rack 6010 to move closer to or away from the central axis of the rotating ring 603.

[0040] In this embodiment, Figure 7-11As shown, an air cavity 6015 is provided in the middle of the inner side of the horizontal rack 6010, and one end of the horizontal rack 6010 close to the central axis of the fixed ring 602 is fixedly connected with four welding rods 6011 and a connecting pipe 6012, and a fixing plate 6013 is welded between the ends of the four welding rods 6011 away from the horizontal rack 6010, and the connecting pipe 6012 penetrates the fixing plate 6013 and is connected with the airbag 6014, and the airbag 6014 and the air cavity 6015 are connected through the connecting pipe 6012, and the air cavities 6015 in the middle of the inner side of the horizontal rack 6010 are connected through a connecting hose 6016; when the horizontal rack 6010 approaches the central axis of the rotating ring 603, the horizontal rack 6010 will drive the fixing plate 6013 and the airbag 6014 at the end to move synchronously, and the airbag 6014 and the cargo When the airbag 6014 contacts the outer surface of the cargo, it will be squeezed. Since the cargo is a regular circle, part of the airbag 6014 is squeezed, while the other part of the airbag 6014 has not yet contacted the cargo. At this time, the internal gas of the squeezed part of the airbag 6014 will enter the air cavity 6015 through the connecting tube 6012, and the gas in the air cavity 6015 will enter the airbag 6014 that is not in contact with the cargo through the connecting hose 6016, expanding the part of the airbag 6014 that is not in contact with the cargo, so that as many airbags 6014 as possible can contact the outer surface of the cargo, thereby limiting the cargo and preventing it from falling due to inertia and other factors during transportation. Multiple sets of horizontal racks 6010 and airbags 6014 are used to cooperate, which can limit the cargo of different shapes, thereby enhancing the adaptability of the limiting component 6.

[0041] In this embodiment, Figure 1 , Figure 4 and Figure 5As shown, the transmission assembly 7 includes a mounting plate 701 fixedly connected to the inner wall of one side of the mounting frame 3, a spring telescopic rod 702 is fixedly connected to one side of the mounting plate 701, an arc-shaped friction plate 703 is fixedly connected to the end of the spring telescopic rod 702 away from the mounting plate 701, the inner ring of the arc-shaped friction plate 703 is fitted with a friction sleeve 704, the friction sleeve 704 is rotatably connected to the inner wall of one side of the mounting frame 3, and a long gear 705 is fixedly connected to one side of the friction sleeve 704, and a spiral cam 706 is fixedly connected to the end of the long gear 705 away from the friction sleeve 704, the inner ring of the arc-shaped friction plate 703 is provided with a plurality of friction ridges, and the outer ring of the friction sleeve 704 is provided with a plurality of friction grooves, and the width of the friction grooves is greater than the width of the friction ridges; the long gear 705 and the vertical rack 5011 are meshed with each other, and the top of the vertical rack 5011 is meshed with each other. The first section is not provided with teeth. This structure can prevent the long gear 705 from rotating when the vertical rack 5011 starts to move up with the movable rod 508, until the top of the goods enters the middle of the limiting assembly 6 under the lifting action of the stacking assembly 5. At this time, the toothed part of the vertical rack 5011 begins to engage with the long gear 705 and drives the long gear 705 to rotate. The long gear 705 drives the spiral cam 706 to rotate, and the spiral cam 706 drives the driven pin 605 to move, thereby rotating the rotating ring 603. The friction sleeve 704, the arc-shaped friction plate 703 and the spring telescopic rod 702 cooperate with each other to limit the long gear 705 when the vertical rack 5011 is not engaged with the long gear 705, thereby preventing the long gear 705 from rotating, and then driving the limiting assembly 6 to release the limit on the goods through the spiral cam 706.

[0042] The use method and advantages of the present invention: When the stacker with adaptive cargo size is used, the working process is as follows:

[0043] When the stacked goods need to be removed, the driving mechanism 2 is used to push the stacking assembly 5 forward, and the clamping plates 509 in the stacking assembly 5 will be inserted into both sides of the goods. Then the hydraulic rod 501 is started to drive the stacking assembly 5 to clamp the goods and then lift them. After lifting, the pad 505 is placed under the goods to prevent the goods from falling. This structure does not require the use of hollow plates to lift the goods when stacking goods, thus saving space when stacking goods. After lifting the goods, the stacking assembly 5 will make the top surface of the goods higher than the top surface of the rotating ring 603 in the limiting assembly 6. At this time, the stacking assembly 5 uses the transmission assembly 7 to drive the limiting assembly 6 to limit the goods to prevent the goods from falling due to inertia and other reasons during rapid transportation.
