Abstract
Description
Technical Field
[0001] This utility model relates to the field of bar (hot-rolled ribbed steel bar) packaging technology, specifically to an automatic bar counting and aligning device. Background Technology
[0002] Currently, domestic bar stock (hot-rolled ribbed steel bars) is packaged in fixed-length bundles, with the number of bars per bundle clearly defined according to specifications and lengths based on market demand. To improve production efficiency, automatic counting machines are generally used to count the products, and after reaching the specified number, they are packaged by a packing machine. However, during the counting process, because the automatic counting machine's recognition system has high requirements for product alignment, the products are transported on roller conveyors. Relying solely on positioning baffles to align the ends is insufficient to effectively fix the position, resulting in uneven product ends. When the ends extend or contract by more than 2cm, the counting error rate increases significantly. This leads to repackaging due to incorrect packaging, increasing production costs and reducing production efficiency.
[0003] Therefore, in order to correct the above-mentioned defects, we propose an automatic bar counting and sizing device. Utility Model Content
[0004] The technical problem solved by this utility model is to provide an automatic counting and aligning device for bar stock.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic bar counting and alignment device, wherein the alignment device is used to align the bars when they are conveyed on a conveyor chain, the alignment device is installed on one side of the conveyor chain, and includes a cylinder seat, a cylinder is installed in the cylinder seat, a connecting plate is installed on the telescopic end of the cylinder, and a push plate is installed on one side of the connecting plate.
[0006] Furthermore, the pusher plate is connected to an inclined guide plate at one end near the material feeding direction of the conveyor chain, and the inclined guide plate is inclined towards the connecting plate.
[0007] Furthermore, the push plate and the connecting plate are connected by a detachable structure, which includes a T-shaped vertical groove on the side of the connecting plate opposite to the push plate and a T-shaped vertical rod fixed on the side of the push plate opposite to the connecting plate. When the push plate and the connecting plate are connected, the T-shaped vertical rod is inserted into the T-shaped vertical groove.
[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model sets the end position of the alignment device baffle stroke by the end position of the fixed length of the bar, and adds a certain margin to the maximum value of the head position deviation length as the cylinder stroke of the alignment device. During normal operation, after the bar hits the fixed length baffle, it rebounds and retracts. The alignment device pushes the retracted bar back to its original position through slow periodic movement, thereby achieving the purpose of head alignment. This reduces the phenomenon of multiple or missing bars caused by inaccurate counting due to uneven bar heads. The device has a simple structure, is easy to maintain, has a reasonable design, is safe and reliable, reduces production costs, is economical and practical, and is easy to promote and apply on a large scale.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0015] This utility model provides a technical solution:
[0016] Please see Figure 1-3An automatic bar counting and alignment device is disclosed. This device aligns bars as they are conveyed on a conveyor chain. Installed on one side of the conveyor chain, the device includes a cylinder base 1 containing a cylinder 2. A connecting plate 3 is mounted on the telescopic end of the cylinder 2, and a push plate 4 is mounted on one side of the connecting plate 3. An electrical control device is also provided. The device sets the end position of the alignment device's baffle stroke based on the bar's fixed length end position, using the maximum deviation of the head position length plus a certain margin as the cylinder stroke. During normal operation, the bar rebounds and retracts after impacting the fixed length baffle. The alignment device pushes the retracted bar back to its original position through slow, periodic movements, achieving head alignment. The cylinder's actuation frequency is set by a time relay based on the bar production speed. Independent switches are provided for on / off operation, allowing for flexible and convenient control by on-site personnel.
[0017] Specifically, when the bar is conveyed by the conveyor chain, cylinder 2 pushes the bar so that the other end of the bar abuts against the positioning baffle set in the opposite direction. All the bars that come over go through this process, so that the heads of all the bars are aligned.
[0018] As cylinder 2 drives push plate 4 to move forward and backward continuously, and bar stock is continuously conveyed on the conveyor chain, push plate 4 is connected to inclined guide plate 5 at the end near the material direction of the conveyor chain. Inclined guide plate 5 is inclined towards connecting plate 3.
[0019] Taking the pusher plate 4 pushing 10 bars at a time as an example, when the pusher plate 4 pushes the first 10 bars to align, the ends of the last 10 bars will move towards the other end along the inclined guide plate 5 to prevent the last 10 bars from being blocked by the pusher plate 4, which has not yet retracted.
[0020] Because the wear on the push plate 4 is significant due to the bar stock, the push plate 4 needs to be replaced periodically. Therefore, the push plate 4 and the connecting plate 3 are connected by a detachable structure. The detachable structure includes a T-shaped vertical groove 7 on the side of the connecting plate 3 opposite to the push plate 4 and a T-shaped vertical rod 6 fixed on the side of the push plate 4 opposite to the connecting plate 3. When the push plate 4 is connected to the connecting plate 3, the T-shaped vertical rod 6 is inserted into the T-shaped vertical groove 7. The upper opening of the T-shaped vertical groove 7 protrudes from the upper end surface of the connecting plate 3, and the height of the T-shaped vertical groove 7 is lower than that of the connecting plate 3. That is, the T-shaped vertical groove 7 on the side of the push plate 4 is inserted into the T-shaped vertical groove 7 from above, and the connection between the push plate 4 and the connecting plate 3 is completed. When disassembling, the push plate 4 can be pulled upward.
[0021] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
