Description

Technical Field

[0001] This invention relates to the field of concrete test block conveying technology, specifically a conveying line with a buffer device. Background Technology

[0002] During the preparation of concrete test blocks, it is usually necessary to transfer the test blocks. For example, after the concrete test blocks have finished curing in the curing area, they need to be transferred out of the curing area via a conveyor line. In the curing area, the concrete test blocks are usually placed on pallets, and the pallets used to support the concrete test blocks are usually placed on pallet racks.

[0003] However, in existing technologies, when concrete specimens are moved out of the warehouse from the pallet rack using a palletizer, the pallets are usually moved together from the pallet rack to the conveyor line. The conveyor line transfers the pallet and concrete specimens simultaneously from the curing chamber. After the specimens are transferred out of the curing chamber, they are picked up by a robotic arm, leaving only the pallet on the conveyor line to continue forward to the vicinity of the operator. Finally, the operator removes the pallet from the conveyor line and stacks it. Since concrete specimens are usually prepared in large batches, manually picking up and stacking the pallets from the conveyor line requires a lot of manpower, and there is a problem with uneven stacking, which causes the pallets to tip over when they are stacked to a certain height. Therefore, it is necessary to improve this defect.

[0004] The above content is only used to help understand the technical solution of the present invention and does not represent an admission that the above content is the closest prior art. Summary of the Invention

[0048] 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.

[0049] Please see Figure 1-7 The present invention provides a technical solution:

[0050] The conveyor line with a buffer device includes a support tray 101 for carrying the test block 100, and further includes:

[0051] The conveying unit 1 is used to convey the carrier plate 101 containing the test block 100;

[0052] The buffer unit 2 includes an output end located on the upper part of the conveying unit 1, a storage component 22 for storing the empty carrier disk 101 after the test block 100 is grasped, and a pushing component 21 located on both sides of the storage component 22 for transferring the empty carrier disk 101 into the storage component 22.

[0053] It should be noted that before the conveying unit 1 transfers the carrier tray 101 containing the test block 100 to the buffer unit 2, the test blocks 100 on the carrier tray 101 are sequentially picked up by the robotic arm. The empty carrier tray 101 is then conveyed forward by the conveying unit 1 to the bottom of the storage component 22. Subsequently, the pushing component 21 pushes the empty carrier tray 101 from the conveying unit 1 into the storage component 22 for stacking and storage. There is no need for manual removal and stacking of the carrier tray 101 from the conveyor line, saving a lot of manpower.

[0054] As an improvement, such as Figure 1-2 As shown, the conveying unit 1 is provided with a forklift station 6 for placing the test block 100 onto the conveying unit 1, a conveying station 5 for transferring the test block 100 from the forklift station 6, and a robot gripping station 4 for removing the test block 100 conveyed by the conveying station 5 along the conveying direction.

[0055] The robot gripping station 4 is located at the output end of the conveying unit 1;

[0056] The forklift station 6 is located at the input end of the conveying unit 1.

[0057] Furthermore, such as Figure 2-3 As shown, the conveying unit 1 includes:

[0058] Bracket 11;

[0059] The first sprocket 12 has two sets coaxially arranged inside the input end of the bracket 11;

[0060] The second sprocket 16 has two sets coaxially arranged inside the output end of the bracket 11;

[0061] The conveyor chain 13 has one end engaged with the first sprocket 12 and the other end engaged with the second sprocket 16, and is used to drive the carrier plate 101 to be conveyed along the conveying station 5.

[0062] The first cylinder 14 is installed at the lower part of the input end of the bracket 11. The upper end of the first cylinder 14 is equipped with a support frame 15, which is used to support the support plate 101 to the upper part of the conveyor chain 13.

[0063] Preferably, a damper 17 is installed at the lower end of the support 11 and below the conveyor chain 13 to ensure that the carrier plate 101 does not slide relative to the conveyor chain 13 during the conveying process.

[0064] Furthermore, such as Figure 2 , Figure 5-6 As shown, the storage component 22 includes:

[0065] The buffer compartment 221 is fixedly connected to the upper end of the bracket 11 and is used to buffer the carrier disk 101;

[0066] Slot 222 is provided on the side of cache compartment 221 and corresponds one-to-one with push component 21, and is used to support the carrier disk 101 inside cache compartment 221.

[0067] Among them, such as Figure 4-6 As shown, the pushing component 21 includes:

[0068] Mounting platform 211 is fixedly installed inside the bracket 11 and located directly below the buffer compartment 221;

[0069] The second cylinder 212 is installed at the lower end of the mounting platform 211, and the driving end of the second cylinder 212 extends from the lower end of the mounting platform 211 to the upper end of the mounting platform 211.

[0070] The lifting plate 213 is fixedly connected to the drive end of the second cylinder 212. The lifting plate 213 corresponds to the bottom opening of the buffer compartment 221 and is used to push the empty carrier plate 101 into the buffer compartment 221 from the upper end of the conveyor chain 13.

[0071] The limiting mechanism 214 is located on both sides of the bottom of the cache slot and is used to limit the support plate 101 at the bottom of the cache compartment 221.

[0072] The limiting block 215 is fixedly connected to the inner side of the bracket 11 and located on both sides of the lifting plate 213, and is used to limit the carrier plate 101 on the conveyor chain 13 to the lower opening of the buffer compartment 221.

[0073] In addition, the limiting mechanism 214 includes:

[0074] The support platform 2141 is provided in two sets, which are respectively fixedly connected to both sides of the bottom of the buffer slot;

[0075] The third cylinder 2142 is installed on the upper end of the support platform 2141;

[0076] The slider 2143 is fixedly connected to the drive end of the third cylinder 2142. The slider 2143 is provided with a rod 21431 at one end of the support plate 101 for limiting the bottom of the support plate 101 after passing through the slot 222.

[0077] The guide rail 2144 is fixedly connected to the upper end of the support platform 2141 and located on both sides of the third cylinder 2142, and is used to limit the movement of the slider 2143.

[0078] As an improvement, the bearing plate 101 is provided with extended edges 1011 on both sides near the top, which are used to support the bearing plate 101 by mounting it on the upper end of the insertion rod 21431.

[0079] As an improvement, such as Figure 1 As shown, one end of the conveying unit 1 relative to the storage component 22 is provided with a palletizing unit 3 for transporting the carrier tray 101 containing the test block 100 onto the conveying unit 1. The palletizing unit 3 includes:

[0080] Slide rail 31;

[0081] The palletizer 32 is slidably mounted on the upper part of the slide rail 31;

[0082] The forks 33 are installed on the upper part of one side of the palletizer 32 and are used to synchronously transport the carrier plate 101 together with the test block 100 to the forklift station 6.

[0083] It should be noted that: such as Figure 1-3 As shown, in the specific implementation of this invention, when the concrete test block 100 needs to be transferred out of the curing area, the palletizer 32 controls the forks 33 to move to the bottom of the support plate 101 placed in the curing area and lift the support plate 101 containing the test block 100. Subsequently, the palletizer 32 moves the support plate 101 containing the test block 100 along the slide rail 31 to directly above the forklift station 6, and activates the first cylinder 14. The first cylinder 14 drives the support frame 15 to move upward, and the support frame 15 lifts the support plate 101 containing the test block 100 on the forks 33. The palletizer 32... The robot moves along the slide rail 31 and drives the forks 33 to move and pick up the next load plate 101 with the test block 100. During this process, the first cylinder 14 drives the support frame 15 to move downward, so that the test block 100 on the load plate 101 on the support frame 15 is placed at the upper end of the conveyor chain 13. The conveyor chain 13 transports the load plate 101 with the test block 100 to the pick-up station 6 via the conveying station 5. Then, the robot grabs the test block 100 on the load plate 101 at the pick-up station 6, thereby achieving the effect of automatically removing the test block 100 from the resting area.

[0084] like Figure 4-5 , Figure 7As shown, after the test block 100 is removed by the robotic arm at the forklift station 6, the remaining empty carrier plate 101 is conveyed forward by the conveyor chain 13 to the limiting block 215. The limiting block 215 limits the empty carrier plate 101 directly below the opening of the buffer bin 221. At this time, the second cylinder 212 is activated, which drives the lifting plate 213 to move upward, so that the carrier plate 101 limited by the limiting block 215 is pushed upward by the conveyor chain 13 into the buffer bin 221. Subsequently, the third cylinder 212 is activated. Cylinder 2142, the third cylinder 2142 drives slider 2143 to move along guide rail 2144. Slider 2143 drives insertion rod 21431 to move directly below extension edge 1011 after passing through slot 222, so that the carrier plate 101 located at the bottom of the buffer compartment 221 is supported and limited. Control the second cylinder 212 to drive lifting plate 213 to move down to the initial position, thereby realizing that the carrier plate 101 does not need to be continuously removed from the conveyor chain 13 by manual labor, saving a lot of manpower.

[0085] like Figure 4-6 As shown, in addition, after the second cylinder 212 drives the lifting plate 213 to push the carrier plate 101 into the buffer bin 221 and is limited by the insertion rod 21431, the next set of carrier plates 101 pushed into the buffer bin 221 will push the previous set of carrier plates 101 to move upward along the buffer bin 221, so that the carrier plates 101 are gradually stacked together along the buffer bin 221, thereby realizing the automatic stacking of the carrier plates 101. The buffer bin 221 limits and guides the carrier plates 101, ensuring that the carrier plates 101 stacked to a certain height will not tip over.
