Description

Technical Field

[0001] This utility model relates to the field of concrete curing technology, and in particular to a backpack palletizer and a concrete curing system. Background Technology

[0002] During construction, concrete needs to be cured in a temperature- and humidity-controlled curing room after pouring. During curing, samples need to be taken from the curing room for performance testing. In existing technologies, the sample transport device can only transport a limited number of samples at a time, typically only one sample can be taken at a time. The device needs to enter and exit the curing room multiple times to obtain enough samples for a single performance test, resulting in low efficiency. Furthermore, repeated entry and exit of the device can easily cause changes in humidity and temperature within the curing room, which is detrimental to curing. Utility Model Content

[0004] Backpack palletizers can transfer more items at once, effectively improving efficiency. When applied to concrete curing systems, they can effectively reduce the number of times the backpack palletizer enters and exits the curing area for sampling, ensuring the stability of the curing area environment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] This utility model discloses a backpack palletizer, including a frame and a moving mechanism for moving the frame. The frame is provided with a transfer storage rack for placing items to be transferred and a picking and placing mechanism for picking and placing items to be transferred. The picking and placing mechanism is located outside the transfer storage rack. A lifting component for driving the picking and placing mechanism to rise and fall is provided between the picking and placing mechanism and the frame. The picking and placing mechanism includes a picking and placing arm that can extend and retract inside and outside the transfer storage rack and a rotating component for driving the picking and placing arm to rotate in the horizontal direction.

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0025] See Figure 1 As shown, this utility model discloses a backpack palletizer, including a frame 1 and a moving mechanism 2 for moving the frame 1. The frame 1 is provided with a transfer storage rack 3 for placing items to be transferred and a pick-and-place mechanism for picking up and placing items to be transferred. The pick-and-place mechanism is located outside the transfer storage rack 3. A lifting component 6 for driving the pick-and-place mechanism to rise and fall is provided between the pick-and-place mechanism and the frame 1. The pick-and-place mechanism includes a pick-and-place arm 4 that can extend and retract inside and outside the transfer storage rack 3 and a rotating component 5 for driving the pick-and-place arm 4 to rotate in the horizontal direction.

[0026] The backpack palletizer is used in the concrete curing system. When sampling is required, the backpack palletizer enters the curing area from the outside through the moving mechanism 2 and moves to the side of the shelf where the concrete sample to be transferred is placed. The rotating component 5 drives the pick-and-place arm 4 to turn to the side where the sample is located, and the lifting component 6 raises and lowers the pick-and-place arm 4 to a suitable height. Then, the pick-and-place arm 4 takes the sample from the shelf, retracts the pick-and-place arm 4, and rotates it to the side of the transfer storage rack 3 through the rotating component 5. Then, the pick-and-place arm 4 is inserted into the transfer storage rack 3 to place the sample that the pick-and-place arm 4 just took from the shelf into the transfer storage rack 3. This completes one sample transfer operation to the transfer storage rack 3. The above operation of transferring the sample to the transfer storage rack 3 can be repeated multiple times. Then, the backpack palletizer with the sample has been transported to the destination outside the curing area by the moving mechanism 2, and the sample is transferred out of the transfer storage rack 3 by the pick-and-place mechanism for performance testing.

[0027] In this embodiment, a transfer storage rack 3 and a pick-and-place mechanism with a retractable pick-and-place arm 4 are provided in the backpack palletizer. The pick-and-place mechanism can be rotated and raised and lowered by the rotating component 5 and the lifting component 6. This allows the backpack palletizer to temporarily store the items to be transferred in the transfer storage rack 3 at the pick-up point, and then take them out from the transfer storage rack 3 after transporting them to the destination. This enables the backpack palletizer to transfer a larger number of items at a time, effectively improving efficiency. When applied to concrete curing systems, it can effectively reduce the number of times the backpack palletizer enters and exits the curing area when sampling, ensuring the stability of the curing area environment.

[0028] In some embodiments, see Figure 3 As shown, the transfer storage rack 3 includes a frame 31, which is connected to the rack 1. The frame 31 has several storage layers 32 arranged vertically inside it, and the frame 31 has a retrieval opening facing the retrieval mechanism.

[0029] For example, the storage layer 32 has 2, 3, 4 or 5 layers, but is not limited to this. Multiple storage layers 32 are provided in the transfer storage rack 3, so that the backpack palletizer can transfer more items to be transferred at one time. The storage layers 32 are arranged vertically, and the picking and placing mechanism can be raised and lowered to a suitable height by the lifting component 6 to take out samples from different storage layers 32 or place samples on different storage layers 32, making the transfer and picking of samples more convenient.

[0030] In some embodiments, see Figure 1 , Figure 2 and Figure 4 As shown, the pick-and-place arm 4 includes a fixed rail 43, a tray 41 slidably mounted on the fixed rail 43, and a telescopic component 42 for driving the tray 41 to extend and retract in the horizontal direction. The tray 41 can support the sample, and together with the lifting mechanism and the telescopic component 42, the sample can be picked up and placed.

[0031] In one embodiment, the telescopic assembly 42 may include a telescopic cylinder (not shown).

[0032] In another embodiment, preferably, see [link to previous embodiment]. Figure 1 , Figure 2 and Figure 4 As shown, the telescopic assembly 42 includes an extension rail 422 slidably disposed on a fixed rail 43, a pallet 41 slidably disposed on the extension rail 422, and a drive member for driving the extension rail 422 and the pallet 41 to extend and retract along the length direction of the extension rail 422 on the pick-up and put-down arm 4.

[0033] In use, the drive unit drives the extension rail 422 and the pallet 41 to extend away from the fixed rail 43 or retract and fold towards the fixed rail 43 along the length of the extension rail 422. The extension rail 422 allows the pallet 41 to extend to a position further away from the fixed rail 43. Compared with the implementation scheme that simply uses a telescopic cylinder to drive the pallet 41 to extend and retract, by setting the extension rail 422 between the fixed rail 43 and the pallet 41, the fixed rail 43, the extension rail 422 and the pallet 41 cooperate with each other to form a three-section retractable structure. This makes the overall length of the pick-and-place arm 4 shorter in the retracted state. When rotating, especially when rotating to the side where the transfer storage rack 3 is located, it is less likely to interfere with the frame 1. At the same time, the extension length of the pick-and-place arm 4 is longer in the extended state, which is conducive to taking out samples located in a deeper position of the shelf. It is more convenient to pick up and place samples. At the same time, the frame 1, the transfer storage rack 3 and the pick-and-place arm 4 can be installed more compactly, and the overall layout of the backpack palletizer is more compact.

[0034] In the first embodiment, the drive includes a power element that controls the extension of the extension rail 422 and the pallet 41 respectively.

[0035] In the second embodiment, preferably, see [link to previous embodiment]. Figure 1 , Figure 2 and Figure 4As shown, the driving component includes a telescopic drive motor 421, a meshing gear on the fixed rail 43, the meshing gear being connected to the telescopic drive motor 421, and a transmission rack 425 on the extension rail 422 for meshing with the meshing gear. The transmission rack 425 is arranged along the length of the extension rail 422. The telescopic assembly 42 also includes a transmission chain (not shown). A first rotating wheel 423 and a first connecting end 424 are sequentially arranged on the fixed rail 43 along the outward extension direction of the support plate 41. A second rotating wheel 426 and a chain groove rail 427 are sequentially arranged on the extension rail 422 along the outward extension direction of the support plate 41. A second connecting end 411 is provided on the support plate 41. One end of the transmission chain is connected to the first connecting end 424, and the other end is sequentially connected to the second connecting end 411 by passing through the first rotating wheel 423, the second rotating wheel 426, and the chain groove rail 427. The first rotating wheel 423, the second rotating wheel 426, and the chain groove rail 427 can limit the reciprocating movement direction of the transmission chain from deviating.

[0036] When the pick-up and drop-off arm 4 needs to extend outward, the telescopic drive motor 421 drives the meshing gear to rotate, which in turn drives the transmission rack 425, which meshes with it, to move outward along the length of the extension rail 422. The extension rail 422 extends outward, which in turn drives the second connecting end 411 to move accordingly. The chain segment of the transmission chain from the first connecting end 424 to the second rotating wheel 426 becomes shorter, and the chain segment of the transmission chain from the second rotating wheel 426 to the second connecting end 411 becomes longer, which drives the pallet 41 to extend outward relative to the extension rail 422.

[0037] When the pick-up and drop-off arm 4 needs to retract inward, the telescopic drive motor 421 drives the meshing gear to rotate, which in turn drives the transmission rack 425, which meshes with it, to move inward along the length of the extension rail 422. As the extension rail 422 moves inward, the second connecting end 411 moves accordingly. The chain segment from the first connecting end 424 to the second rotating wheel 426 becomes longer, while the chain segment from the second rotating wheel 426 to the second connecting end 411 becomes shorter, causing the pallet 41 to move inward relative to the extension rail 422.

[0038] By working together with the telescopic drive motor 421, meshing gears, transmission rack 425 and transmission chain, the same power element can drive the movement of the extension rail 422 and the pallet 41, resulting in higher integration of the pick-up and put-out arm 4 and simpler retraction control.

[0039] The transmission chain has two sets, located on both sides of the width of the extension rail 422, making the transmission smoother.

[0040] In some embodiments, see Figure 2As shown, a gear set is provided between the telescopic drive motor 421 and the meshing gear. The fixed rail 43 is provided with a strip-shaped receiving groove 431. The strip-shaped receiving groove 431 is arranged along the length direction of the extension rail 422. The meshing gear and the gear set are located in the strip-shaped receiving groove 431. The transmission rack 425 extends at least partially into the strip-shaped receiving groove 431 and meshes with the meshing gear.

[0041] In some embodiments, the transmission chain may include a chain and connecting rods disposed at both ends of the chain. The connecting rods are respectively connected to the first wheel 423 and the first connecting end 424, which is beneficial to the stability of the transmission.

[0042] In some embodiments, see Figure 2 and Figure 3 As shown, the bottom of the storage layer 32 has a perforation for the tray 41 to pass through.

[0043] When a sample needs to be retrieved from a storage layer 32 of the transfer storage rack 3, the tray 41 moves and is raised or lowered by the lifting assembly 6 to the area below the storage layer 32 where the sample to be transferred is located. The tray 41 extends into the transfer storage rack 3, and then the lifting assembly 6 lifts the tray 41. The tray 41 moves from below the storage layer 32 through the cutout and into the storage layer 32, lifting the sample placed on the bottom of the storage layer 32 and removing it from the bottom. The sample is transferred to the area above the tray 41. Then the tray 41 is retracted, and the tray 41 with the sample is moved out of the transfer storage rack 3. Conversely, the tray 41 with the sample is moved down through the cutout of the storage layer 32, and the sample can be placed on the storage layer 32. The transfer storage rack 3 has a simple structure, and the transfer and retrieval of samples is simple.

[0044] In some embodiments, see Figure 1 and Figure 2 As shown, the lifting assembly 6 includes a lifting base 61 and a lifting rack 62. The lifting base 61 is slidably mounted on the frame 1. The lifting base 61 has a horizontally arranged rotating shaft and a lifting drive motor 63 that drives the rotating shaft to rotate. A first gear 64 is sleeved on the outside of the rotating shaft 65. The lifting rack 62 is arranged vertically and meshes with the first gear 64. The gear and rack lifting structure provides smoother lifting and less operating noise.

[0045] In some embodiments, preferably, two sets of lifting rack 62 and first gear 64 are provided, so that the lifting seat 61 can be lifted more smoothly.

[0046] In some embodiments, see Figure 2 and Figure 4 As shown, the rotating assembly 5 is mounted on the lifting seat 61. The rotating assembly 5 includes a rotating shaft and a rotating motor 51 for driving the rotating shaft to rotate. The rotating shaft is arranged in a vertical direction and is located below the pick-and-place arm 4.

[0047] In this embodiment, the rotating shaft is connected to the bottom of the fixed rail 43.

[0048] A gearbox can also be installed between the rotary motor 51 and the rotary shaft.

[0049] In some embodiments, see Figure 1 , Figure 5 and Figure 6 As shown, the palletizer is also equipped with an upper rail 71, a lower rail 72 and a positioning rack 73 that are parallel to each other. An upper roller is provided above the frame 1 and slides on the upper rail 71. The moving mechanism 2 includes a base 21, a lower roller provided below the base 21 and a moving motor 22 for driving the lower roller to move. The lower roller slides on the lower rail 72. A transmission shaft 23 is provided between the moving motor 22 and the lower roller. A positioning gear 74 is provided on the outside of the transmission shaft 23. The positioning rack 73 is provided below the base 21 and meshes with the positioning gear 74.

[0050] In this embodiment, the precise positioning of the palletizer is achieved through the cooperation between the positioning rack 73 and the positioning gear 74, which helps to improve sampling efficiency.

[0051] In some embodiments, see Figure 1 and Figure 3 As shown, the frame 1 includes a first column 11 and a second column 12 that are parallel to each other. The transfer storage rack 3 is connected to the first column 11 and the second column 12 respectively. The transfer storage rack 3 is located on one side of the plane where the first column 11 and the second column 12 are located, and the pick-and-place mechanism is located on the other side of the plane where the first column 11 and the second column 12 are located, so that the pick-and-place arm 4 is not easily interfered with by the transfer storage rack 3 during rotation, and the rotation angle of the pick-and-place arm 4 is wider and more convenient to use.

[0052] This utility model also discloses a concrete curing system, including the aforementioned backpack palletizer.

[0053] The concrete curing system in this embodiment uses the aforementioned backpack palletizer, which can effectively reduce the number of times the backpack palletizer enters and exits the curing area during sampling, ensuring the stability of the curing area environment, and has high sampling efficiency.

[0054] Of course, the above illustrations are only preferred embodiments of this utility model and are not intended to limit the scope of application of this utility model. Therefore, any equivalent changes made to the principle of this utility model should be included within the protection scope of this utility model.
