Compared with the horizontal conveying mechanism, the present utility model makes full use of the vertical working space, thereby saving the horizontal working space, shortening the length of the equipment, and reducing the floor area.

[0025] In some other specific embodiments of the present utility model, the rest is the same as the above embodiments, except that, as Figure 1 shown, the main bracket lifting mechanism includes a cross beam 0101, a slide rail 0102, a conveyor belt 0103, and a servo motor 0104. The two main brackets 0200 are connected into one body by the cross beam 0101. A slider is arranged at the bottom of the cross beam 0101 and is located in the slide rail 0102. The slide rail 0102 is fixedly arranged on the wall panel 0800 up and down. The servo motor 0104 is fixed at the bottom of the wall panel 0800, and the servo motor 0104 drives the cross beam 0101 to move up and down through the conveyor belt 0103.

[0026] In some other specific embodiments of the present utility model, the rest is the same as the above embodiments, except that, as Figure 1 and Figure 2As shown, both ends of the crossbeam 0101 are connected to the fixed plates 0206. A cylinder seat 0202 and a bracket slider 0205 are fixed on the fixed plates 0206. A cylinder 0201 on the cylinder seat 0202 drives the piston rod 0203 to extend and retract.

When the main bracket 0200 retracts, it withdraws from the paths formed by the front stop rod 0400 and the rear stop rod 0500. When the main bracket 0200 descends to the bottom and docks with the conveying plate 0700, the cylinder 0201 drives the main bracket 0200 to retract, so that the glass tube stack moves onto the conveying plate 0700. When the main bracket 0200 rises to the top receiving area, it is controlled by the cylinder 0201 to extend.

[0027] In some other specific embodiments of the present invention, the rest is the same as the above embodiments, except that, as Figure 1 and Figure 3 shown, a secondary bracket 0300 is respectively arranged beside the pair of main brackets 0200. The secondary bracket 0300 is fixed on the upper part of the wall panel 0800 and is driven by a secondary bracket cylinder to extend or retract. When it extends, the secondary bracket 0300 is located between the paths formed by the front stop rod 0400 and the rear stop rod 0500. When the secondary bracket 0300 retracts, it withdraws from the paths formed by the front stop rod 0400 and the rear stop rod 0500. During the process of the main bracket 0200 descending, the secondary bracket 0300 can replace the main bracket 0200 to store the next batch of glass tube stacks. After the main bracket 0200 rises, when it rises slightly higher than the secondary bracket 0300, it can lift the glass tubes on the secondary bracket mechanism 0300. Then the secondary bracket 0300 is driven by the cylinder to retract, and the main bracket 0200 can descend to convey a new batch of glass tubes. The present invention adopts the main bracket and the secondary bracket to work alternately, and can realize the uninterrupted vertical lifting and conveying of glass tube products.

It is convenient to adjust the front and rear positions of the rear stop rod 0500.

[0029] In some other specific embodiments of the present invention, the rest is the same as the above embodiments, except that, as Figure 4As shown, the rear baffle adjusting mechanism 0600 includes a stepper motor 0601, a nut 0602, a lead screw 0603, a baffle slider 0604, a baffle slide rail 0605, an adjusting beam 0606 and a mounting plate 0607. The middle of the mounting frame 0501 is connected as a whole through the adjusting beam 0606. Baffle sliders 0604 are provided on both sides of the bottom of the adjusting beam 0606. The baffle sliders 0604 are arranged in the baffle slide rail 0605. The stepper motor 0601 is arranged on the mounting plate 0607. The stepper motor 0601 drives the lead screw 0603. The lead screw 0603 is connected to the adjusting beam 0606 through the nut 0602. After the stepper motor 0601 is started, the lead screw 0603 drives the adjusting beam 0606 to move back and forth in the baffle slide rail 0605. The rear baffle 0500 moves together with the mounting frame 0501 and the adjusting beam 0606, realizing the adjustment of the front and rear positions of the rear baffle 0500 to meet the width requirements of the front and rear baffles for products of different specifications.

[0030] In some other specific embodiments of the present invention, the rest is the same as the above embodiments, except that, as Figure 5 shown, sprockets 0701 are provided on both sides of the bottom of the wall panel 0800. A chain 0702 is driven on the sprockets 0701. The conveying plate 0700 is laid on the chain 0702. A lower baffle 0703 is provided on the conveying plate 0700. The lower baffles 0703 are in groups of two. A placement space for the glass tube 0900 is formed between every two lower baffles 0703. When the main bracket 0200 descends to the bottom and then retreats, the lower baffle 0703 can block the glass tube 0900 and leave it in this placement space. At this time, the glass tube 0900 in the lower baffle 0703 can be wound and packaged by using a packing device. After the packaging is completed, the chain 0702 drives the conveying plate 0700 to move and send away the glass tube 0900.

[0031] In some other specific embodiments of the present invention, the rest is the same as the above embodiments, except that, as Figure 1 shown, multiple groups of the lower baffles 0703 are provided and evenly distributed on the conveying plate 0700. Each group of the lower baffles 0703 is a packaging station. With multiple packaging stations, after the glass tube stack is packaged, the chain 0702 drives the tube stack to be conveyed to the next station. At this time, the next group of the lower baffles 0703 reaches the packaging position to form a packaging station and waits for the arrival of the next group of products, and can operate cyclically.

[0032] Combined with the above embodiments, the working process of the present invention is as follows: As Figure 6 shown, the bundling equipment stacks the glass tubes 0900 layer by layer on the main bracket 0200. The glass tubes 0900 are blocked by the front baffle 0400 and the rear baffle 0500 and will not roll. When the glass tubes 0900 reach the specified quantity or height, as Figure 7As shown, the main bracket lifting mechanism drives the main bracket 0200 to hold the product and descend within the path width restricted by the front stop bar mechanism 0400 and the rear stop bar mechanism 0500 under the drive of the servo motor 0104. When the product descends onto the lower stop bar conveyor plate 0700, as Figure 8 shown, the packaging equipment wraps and fixes both ends of the glass tube with plastic film at this station. At the same time, the Yamabe sub-bracket 0300 extends under the action of the cylinder, and the bundling equipment stacks the next group of glass tubes 0900 onto the sub-bracket 0300, while the bottom main bracket 0200 retracts under the action of the cylinder, leaving the glass tubes 0900 on the conveyor plate 0700. The main bracket 0200 rises under the control of the lifting mechanism. During the rising process, the main bracket 0200 extends again through the cylinder and continues to rise slightly higher than the sub-bracket 0300, replacing the sub-bracket 0300 to hold the glass tubes. Then the sub-bracket 0300 retracts driven by the cylinder, and the main bracket 0200 can descend to convey a new batch of glass tubes. The glass tubes 0900 on the conveyor plate 0070 at the bottom are packed and conveyed to the next process during the rising and falling of the main bracket 0200. By operating in this cycle, the uninterrupted vertical conveyance of the glass tube bundle products is achieved.
