Description

Technical Field

[0001] The invention relates to the technical field of concrete test block conveying, in particular to a conveying line with a buffer device. Background Art

[0002] During the preparation process of concrete test blocks, it is usually necessary to transfer the positions of the test blocks. For example, after the curing work of the concrete test blocks in the resting area is completed, the concrete test blocks need to be transferred out of the curing area through a conveyor line. The concrete test blocks are usually placed on pallets in the curing area, and the pallets used to carry the concrete test blocks are usually placed on pallet racks.

[0003] However, in the prior art, when the concrete specimens are transported out of the warehouse from the pallet rack by the palletizer, they usually need to be transported from the pallet rack to the conveyor line together with the pallet. The conveyor line transfers the pallet and the concrete specimens out of the curing room synchronously. After the specimens are transferred out of the curing room, they are clamped by the robot. Only the pallet remains on the conveyor line and continues to be transported forward to the vicinity of the operator. Finally, the operator takes the pallet out of the conveyor line and stacks it. Since concrete specimens are usually prepared in large batches, it takes a lot of manpower to manually take the pallets from the conveyor line and stack them, and there is a phenomenon of uneven manual stacking, which causes the pallet to tip over when it is stacked to a certain height. Therefore, it is necessary to improve this defect.

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

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

[0066] The slot 222 is provided at the side of the buffer chamber 221 and corresponds one-to-one with the push assembly 21 , and is used to support the carrier plate 101 inside the buffer chamber 221 .

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

[0068] The mounting platform 211 is fixedly mounted inside the bracket 11 and is located directly below the buffer bin 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 passes through the lower end of the mounting platform 211 to the upper end of the mounting platform 211;

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

[0071] The limiting mechanism 214 is provided on both sides of the bottom of the buffer slot, and is used to limit the carrier plate 101 at the bottom of the buffer bin 221;

[0072] The limiting blocks 215 are fixedly connected to the inner side of the bracket 11 and are located on both sides of the lifting plate 213 , and are used to limit the carrying plate 101 on the conveying chain 13 at the lower end opening of the buffer bin 221 .

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

[0074] The support platform 2141 is provided with two groups, which are respectively fixedly connected to the two 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] A slider 2143 is fixedly connected to the driving end of the third cylinder 2142. The slider 2143 is located at one end of the carrier plate 101 and is provided with an insertion rod 21431 for limiting the bottom of the carrier 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 is 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 two sides of the carrier plate 101 are provided with extension edges 1011 on the upper side, which are used to be mounted on the upper end of the insertion rod 21431 to support the carrier plate 101;

[0079] As an improvement, Figure 1 As shown, the conveying unit 1 is provided with a stacking unit 3 at one end opposite to the storage assembly 22 for transporting the carrier plate 101 with the test block 100 to the conveying unit 1, and the stacking unit 3 includes:

[0080] Slide rail 31;

[0081] A palletizer 32 is slidably disposed on the upper portion of the slide rail 31;

[0082] The fork 33 is installed on the upper part of one side of the palletizer 32 and is used to synchronously transport the carrier plate 101 and the test block 100 to the forking station 6 .

[0083] It should be noted that: Figure 1-3 As shown, in the specific implementation process of the present invention, when the concrete test block 100 needs to be transferred out of the curing area, the palletizer 32 controls the fork 33 to move to the bottom of the carrier 101 placed in the resting area and lifts the carrier 101 with the test block 100. Subsequently, the palletizer 32 moves the carrier 101 with the test block 100 along the slide rail 31 to just above the forking station 6, and starts the first cylinder 14. The first cylinder 14 drives the carrier 15 to move upward, and the carrier 15 lifts the carrier 101 with the test block 100 on the fork 33. The palletizer 32 Move along the slide rail 31 and drive the fork 33 to move and fork the next set of carrier trays 101 with test blocks 100. In this process, the first cylinder 14 drives the carrier 15 to move downward, so that the test block 100 on the carrier tray 101 on the carrier 15 is placed on the upper end of the conveying chain 13. The conveying chain 13 conveys the carrier tray 101 with the test block 100 to the forking station 6 through the conveying station 5. Then, the manipulator grabs the test block 100 on the carrier tray 101 at the forking station 6, thereby achieving the effect of automatically moving the test block 100 out of the resting area;

[0084] like Figure 4-5 , Figure 7As shown, after the test block 100 is taken out by the robot at the fork-taking station 6, the remaining empty carrier plate 101 is further conveyed forward by the conveying chain 13 to the limit block 215, and the limit block 215 limits the empty carrier plate 101 just below the opening of the buffer bin 221. At this time, the second cylinder 212 is started, and the second cylinder 212 drives the lifting plate 213 to move upward, so that the carrier plate 101 limited by the limit block 215 is pushed upward by the conveying chain 13 into the buffer bin 221, and then the third cylinder 212 is started. The air cylinder 2142 and the third air cylinder 2142 drive the slider 2143 to move along the guide rail 2144. The slider 2143 drives the insertion rod 21431 to move to the bottom of the extension edge 1011 after passing through the slot 222, so that the carrier plate 101 located at the bottom of the buffer bin 221 is supported and limited, and the second air cylinder 212 is controlled to drive the lifting plate 213 to move downward to the initial position, thereby realizing that the carrier plate 101 does not need to be taken out from the conveying chain 13 continuously by manual labor, saving a lot of manpower;

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