Description

Technical Field

[0001] This application relates to the field of overhead conveyor technology, and in particular to an intelligent overhead conveyor line for vacuum compression bag production. Background Technology

[0002] The intelligent suspended conveyor line for vacuum compression bags is a conveying device used in vacuum compression bag production lines to transport vacuum compression bags.

[0003] The production of vacuum compression bags involves multiple processing steps, with semi-finished and finished bags transferred between each step via overhead conveyor lines. Overhead conveyor lines have the advantages of being adaptable to assembly line layouts, capable of continuous cyclical operation, adaptable to flexible bag transfer, and having a small footprint, making them the core transfer and conveying equipment for automated vacuum compression bag production.

[0004] Current overhead conveyor systems typically consist of a track, an overhead conveyor chain and overhead conveyor supports, a drive unit, and a fixing mechanism suspended at the bottom of the overhead conveyor supports. Currently, in the process of conveying individual vacuum compression bags, the overhead conveyor line uses an intermittent start-stop method. The vacuum compression bags are then manually placed into the fixing mechanism and conveyed through it. The conveying and fixing method generally uses vacuum adsorption. With vacuum adsorption, the vacuum compression bags are prone to falling during the intermittent start-stop conveying process, especially when there is airflow under the fan or air conditioning vent. In addition, the vacuum adsorption method requires a vacuum extraction pipe to be installed on each overhead conveyor support, making the equipment relatively complex. Summary of the Invention

[0005] Therefore, it is necessary to provide an intelligent suspended conveyor line for vacuum compression bag production to address the aforementioned technical problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an intelligent suspended conveyor line for vacuum compression bag production, comprising a suspended conveyor chain and a suspended conveyor support, and further comprising: A suspension mounting bracket is installed at the bottom of the suspension conveyor support; A compression bag placement plate is fixedly connected to the bottom of the hanging mounting bracket; A rotating fixing plate is rotatably connected to the bottom of the hanging mounting frame, and the rotating fixing plate is used to fix the vacuum compression bag on the compression bag placement plate; The mounting slot is provided on the side of the rotating fixing plate facing the compression bag placement plate; An elastic arc-shaped roller is rotatably connected within the mounting groove, with the arc-shaped protrusion in the middle of the roller extending out of the mounting groove.

[0007] In order to flatten the bottom of the vacuum compression bag, preferably, two connecting rods are symmetrically installed on the bottom of the rotating fixing plate, and a rotating roller is provided between the ends of the two connecting rods away from the rotating fixing plate.

[0008] Preferably, a torsion spring rotating shaft is installed at the connection between the connecting rod and the rotating roller.

[0009] Preferably, multiple sets of telescopic cylinders are rotatably connected to the rotating fixed plate. The other end of the telescopic cylinder is rotatably connected to the suspension mounting bracket. A return spring is sleeved on the telescopic end of the telescopic cylinder. One end of the return spring abuts against the cylinder body of the telescopic cylinder, and the other end is fixedly connected to the telescopic end of the telescopic cylinder. The telescopic cylinder is provided with an air inlet and an air outlet, and a one-way valve is installed in both the air inlet and the air outlet.

[0010] Preferably, the compression bag placement plate is provided with multiple sets of adsorption holes at equal intervals, and the adsorption holes are connected to the air inlet end of the telescopic cylinder.

[0011] To prevent the vacuum compression bag from tilting, preferably, the diameter of the adsorption pores gradually increases from the middle to both ends.

[0012] Preferably, an air inlet pipe is connected to the air inlet end of the telescopic cylinder, and an adsorption pipe communicating with the adsorption hole is provided inside the compression bag placement plate, with the air inlet pipe and the adsorption pipe being connected.

[0013] To control the rotation speed, preferably, a flow-dividing regulating valve is installed on the suspension mounting bracket. The flow-dividing regulating valve is provided with a first air inlet, a third air inlet, and a constant port output in sequence. The constant port output is connected to the air inlet pipe, the first air inlet is connected to the connecting pipe, and the third air inlet is connected to the outside. The flow-dividing regulating valve is provided with an adjustment port inside. The adjustment port is fixedly connected to the rotation shaft of the rotating fixed plate. The adjustment port is connected to the constant port output through a rotary sealing connection unit, and a control pipeline is provided on the adjustment port.

[0014] Preferably, the diversion regulating valve is provided with a second air inlet, and the second air inlet is connected to the connecting pipe, and the diameter of the control pipe is 1.5 times the diameter of the first air inlet.

[0015] Preferably, a sleeve is fixedly connected in the mounting groove, a spring is installed in the sleeve, and the two ends of the elastic arc-shaped roller are slidably connected in the sleeve and abut against the spring.

[0016] Compared with the prior art, the present invention provides an intelligent suspended conveyor line for vacuum compression bag production, which has the following advantages: This invention uses an elastic arc-shaped roller for fixed conveying, which can ensure the stability of vacuum compression bag conveying and prevent it from falling during the conveying process. In addition, the elastic arc-shaped roller can flatten the vacuum compression bag, preventing wrinkles from forming during the conveying and fixing process, which would affect the processing quality. Furthermore, there is no need to set up a complicated vacuum adsorption pipeline, making the equipment simpler and reducing the failure rate. At the same time, the rotating fixing plate and the rotating roller move downward to flatten and tighten the vacuum compression bag. Together with the compression bag placement plate, the vacuum compression bag is kept in a flat state, and the lower end of the vacuum compression bag is fixed. At this time, the vacuum compression bag can be prevented from falling during the conveying process. Even if it passes through the airflow area of ​​the fan or air conditioning vent, there will be no large shaking, which prevents the vacuum compression bag from falling and prevents the wind from causing wrinkles on its surface. Furthermore, the compression bag placement plate is equipped with multiple sets of suction holes at equal intervals. During the rotation and resetting of the fixing plate, the suction holes will generate suction force. After the staff places the vacuum compression bag, the suction force generated by the suction holes will help to pre-fix the placed vacuum compression bag, preventing the vacuum compression bag from falling off before it is fully fixed. Moreover, there is no need to configure a vacuum extraction pipe, making it easy to use. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0020] Example: Refer to Figure 1 , Figure 2 A smart suspended conveyor line for vacuum compression bag production includes a suspended conveyor chain 1 and a suspended conveyor support 2, wherein the suspended conveyor chain 1 is driven by a drive unit to move cyclically along the entire conveyor line. In a specific implementation, the intelligent overhead conveyor line is arranged along the processing steps, and then the overhead conveyor chain 1 is driven by the drive unit to move cyclically. The overhead conveyor supports 2 are arranged on the overhead conveyor chain 1 at set intervals. When the overhead conveyor chain 1 stops moving, the vacuum compression bag is manually placed in the fixing mechanism. At this time, the fixing mechanism has vacuum adsorption holes, and the vacuum compression bag is fixed by vacuum adsorption. Then the overhead conveyor chain 1 starts to transport the vacuum compression bag. During the transport process, the following problems may exist. First, when the overhead conveyor chain 1 stops moving and moves instantaneously, the vacuum compression bag has a certain inertial force. In particular, the heavy vacuum compression bag is prone to positional displacement. Second, since the workshop is generally equipped with equipment such as fans and air conditioners, there is airflow under the air outlet of the fan or air conditioner. If the overhead conveyor line passes through the area of ​​airflow, it may fall and affect subsequent processing. Third, the vacuum adsorption method requires a vacuum extraction pipe to be configured for each overhead conveyor support 2, which makes the equipment relatively complex and the related pipeline layout more complicated.

[0021] To address the current problems with intelligent overhead conveyor lines, the following implementation methods can be adopted, such as... Figure 4 , Figure 5 , Figure 7 , Figure 13 , Figure 14 As shown, a hanging mounting bracket 3 is installed at the bottom of the hanging conveyor bracket 2. A compression bag placement plate 4 is fixedly connected to the bottom of the hanging mounting bracket 3. A rotating fixing plate 5 is rotatably connected to the bottom of the hanging mounting bracket 3. An installation groove is provided on the side of the rotating fixing plate 5 facing the compression bag placement plate 4. An elastic arc roller 901 is rotatably connected in the installation groove. In a specific implementation, when the worker places the vacuum compression bag onto the suspended conveyor line, the rotating fixing plate 5 first rotates open, then the vacuum compression bag is placed on the compression bag placement plate 4. The rotating fixing plate 5 then resets to fix the vacuum compression bag. The protruding end in the middle of the elastic arc roller 901 first contacts the central area of ​​the vacuum compression bag, and as it continues to press down, the two sides of the arc surface of the elastic arc roller 901 gradually adhere to and spread out to both sides of the bag surface. Utilizing the lateral stretching force generated by the arc contour, the bag surface is pushed and flattened to both sides. The method of fixing with the elastic arc roller 901 can ensure the stability of the vacuum compression bag and prevent it from falling during the conveying process. Furthermore, the elastic arc roller 901 can flatten the vacuum compression bag, preventing wrinkles from forming during the conveying and fixing process, which would affect its processing quality. In addition, there is no need to set up complex vacuum adsorption pipelines, making the equipment simpler and reducing the failure rate.

[0022] In a preferred embodiment, such as Figure 15As shown, a sleeve 902 is fixedly connected in the mounting groove, and a spring 903 is installed inside the sleeve 902. The two ends of the elastic arc roller 901 are slidably connected inside the sleeve 902 and abut against the spring 903. The sleeve 902 can restrict the movement of the elastic arc roller 901, so that it moves stably along the sleeve 902 and avoids skewing. The spring 903 is used to reset the elastic arc roller 901, which is convenient for subsequent reuse.

[0023] In a preferred embodiment, such as Figure 3 , Figure 6 , Figure 8 , Figure 9 , Figure 10 As shown, two connecting rods 601 are symmetrically installed at the bottom of the rotating fixed plate 5. A rotating roller 602 is provided between the ends of the two connecting rods 601 away from the rotating fixed plate 5. (Refer to...) Figure 8 A torsion spring rotating shaft 603 is installed at the connection between the connecting rod 601 and the rotating roller 602. When the rotating fixed plate 5 is opened, the rotating roller 602 rotates to the left along the axis of the torsion spring rotating shaft 603 under the action of the torsion spring rotating shaft 603. When the rotating fixed plate 5 is reset, after the elastic arc roller 901 contacts the vacuum compression bag for a certain length, the rotating roller 602 first contacts the lower part of the vacuum compression bag. As the rotating fixed plate 5 continues to rotate, the rotating roller 602 moves downward to flatten and tighten the vacuum compression bag, and works with the compression bag placement plate 4 to keep the vacuum compression bag in a flat state. In addition, it also has the effect of fixing the lower end of the vacuum compression bag. At this time, the vacuum compression bag can be prevented from falling during the conveying process. At the same time, even if it passes through the airflow area of ​​the fan or air conditioning vent, there will be no large shaking, which can prevent the vacuum compression bag from falling and prevent the wind from causing wrinkles on its surface.

[0024] When the vacuum compression bag needs to be removed in the later process, the worker simply pulls on both ends of the bottom edge of the vacuum compression bag, as shown in the reference. Figure 10 Pull the vacuum compression bag to the right or lower right. At this time, the vacuum compression bag will squeeze the rotating roller 602 to the right, so that the rotating fixing plate 5 is in an open state, making it easier to take out the vacuum compression bag. After the vacuum compression bag is no longer squeezed, the rotating fixing plate 5 returns to the vertical position. At this time, the rotating roller 602 can press the vacuum compression bag tightly, so that it is in a pressed state when it is pulled out, preventing the flexible vacuum compression bag from collapsing and wrinkling. It is also easy to lay it flat and stack it on the worktable without re-leveling, thus improving its processing efficiency.

[0025] Furthermore, such as Figure 3 , Figure 6 As shown, each of the two connecting rods 601 is equipped with a hand lever 604. The hand lever 604 makes it easy for the operator to pull the connecting rod 601 when facing the rotating fixed plate 5, thus facilitating the operator's use.

[0026] In a preferred embodiment, such as Figure 11 , Figure 12 As shown, multiple sets of telescopic cylinders 701 are rotatably connected to the rotating fixed plate 5. The other end of the telescopic cylinder 701 is rotatably connected to the suspension mounting bracket 3. A return spring 702 is sleeved on the telescopic end of the telescopic cylinder 701. One end of the return spring 702 abuts against the cylinder body of the telescopic cylinder 701, and the other end is fixedly connected to the telescopic end of the telescopic cylinder 701. The telescopic cylinder 701 is equipped with an air inlet and an air outlet. A one-way valve is installed in both the air inlet and the air outlet. When the rotating fixed plate 5 is rotated, the telescopic cylinder 701 first discharges air. When the rotating fixed plate 5 is reset, the telescopic cylinder 701 draws air in. The diameter of the air inlet is small and the diameter of the air outlet is large, so as to easily open the rotating fixed plate 5 and allow the rotating fixed plate 5 to reset at a slower speed.

[0027] Multiple sets of suction holes 402 are evenly spaced on the compression bag placement plate 4. The suction holes 402 are connected to the air inlet end of the telescopic cylinder 701. During the process of rotating the fixing plate 5 to reset, the suction holes 402 will generate suction. After the staff places the vacuum compression bag, the suction generated by the suction holes 402 will pre-fix the placed vacuum compression bag to prevent the vacuum compression bag from falling before it is fully fixed.

[0028] In a preferred embodiment, such as Figure 7 As shown, the size of the adsorption hole 402 is small in the middle and gradually expands towards both ends. This way, when the vacuum compression bag is adsorbed and fixed, the large holes at both ends can increase the air extraction cross-sectional area, increase the adsorption stability, and prevent the vacuum compression bag from tilting after being placed on it. At the same time, it can ensure that the two ends of the vacuum compression bag are straightened. Specifically, this is because the staff holds the vacuum compression bag by its two ends when placing it, and the strong adsorption at both ends is more effective in preventing it from falling.

[0029] In a preferred embodiment, such as Figure 5 , Figure 16 As shown, a flow control valve 8 is installed on the suspension mounting bracket 3. The flow control valve 8 is provided with a first air inlet 802, a second air inlet 803, a third air inlet 804 and a constant port output 801 in sequence. The constant port output 801 is connected to the air inlet pipe 703. The first air inlet 802 and the second air inlet 803 are both connected to the connecting pipe 704. The third air inlet 804 is connected to the outside. The adjustment port of the flow control valve 8 is fixedly connected to the rotating shaft of the rotating fixed plate 5. The adjustment port is connected to the constant port output 801 through a rotating sealing connection unit. The adjustment port is provided with a control pipe 805. The diameter of the control pipe 805 is 1.5 times the diameter of the first air inlet 802. In a specific embodiment, the adjusting port is connected to the rotating shaft of the rotating fixing plate 5. The rotating shaft controls the rotation of the adjusting port to realize the rotation of the control pipe 805. In a specific configuration, the rotating fixing plate 5 can rotate 70 degrees, which is the angle between the rotating fixing plate 5 and the compression bag placement plate 4. When the rotating fixing plate 5 returns to 45-35 degrees, the control pipe 805 is simultaneously connected to the first air inlet 802 and the second air inlet 803, providing a greater suction force to strengthen the fixation of the vacuum compression bag and prevent it from falling after the operator removes their hand, providing a stable fixation state for subsequent fixation. When the rotating fixing plate 5 returns to 20 degrees, the elastic arc roller 901 contacts the vacuum compression bag. At this time, the connection area between the control pipe 805 and the first air inlet 802 and the second air inlet 803 changes. The smaller size allows for a gradual reduction in the suction force on the vacuum compression bag, facilitating the smoothing of the upper edge of the vacuum compression bag by the elastic arc roller 901, preventing wrinkles from forming in the middle. When the rotating fixing plate 5 is reset to 5 degrees, the control pipe 805 is no longer connected to the first air inlet 802 and the second air inlet 803. At this time, the elastic arc roller 901 fixes the vacuum compression bag for a certain length, preventing it from falling off. The control pipe 805 is also connected to the third air inlet 804, drawing in external gas. The suction hole 402 no longer has suction force, and the elastic arc roller 901 smooths both sides of the upper edge of the vacuum compression bag. Since the suction holes 402 on both sides are larger and have greater suction force, the vacuum compression bag may become concave. Smoothing the bag while it is not suctioning improves the smoothing effect and prevents wrinkles from forming.
