Description

Technical Field

[0001] The invention relates to automatic ranking, in particular to an automatic ranking mechanism and a ranking method thereof. Background Art

[0002] Corrugated cardboard is a multi-layer adhesive body, which consists of at least one layer of corrugated core paper (commonly known as "corrugated paper", "corrugated core paper", "corrugated paper core", "corrugated base paper") and one layer of cardboard (also known as "boxboard", "boxboard"). It has high mechanical strength and can withstand collisions and falls during transportation.

[0003] At present, common corrugated paperboard is generally made of corrugated paper sandwiched between upper and lower paperboards, and its strength and toughness are average. When designing packaging boxes for some valuable items, ordinary corrugated paperboard cannot meet the strength and toughness requirements. To solve the above problems, cotton thread is often added to corrugated paper. Please refer to the application number CN201820942496.8, which is a patent for a high-strength corrugated paperboard.

[0004] There are two main types of existing positioning mechanisms: one is manual positioning, which relies on manual movement of the workpiece to the working position, which is time-consuming and labor-intensive, inefficient, inaccurate, and has potential safety hazards. The other is automatic positioning, but the existing automatic positioning mechanism has a complex structure, a large volume, and high maintenance costs, and cannot be used in many places with small spaces and harsh environments. Summary of the invention

[0005] The invention provides an automatic ranking mechanism and a ranking method which can automatically rank workpieces.

[0006] The technical solution adopted by the present invention to solve its technical problems is: an automatic ranking mechanism includes a frame part and a slide part, the slide part and the frame part are connected, wherein: the frame part includes: a guide rail beam, a guide rail, a synchronous belt, a servo motor, a synchronous pulley, and an electromagnetic valve box, the guide rail, the servo motor and the synchronous pulley are all installed on the guide rail beam, the synchronous belt is wrapped around the synchronous pulley, and the servo motor drives the synchronous belt to rotate through the synchronous pulley; the slide part includes: a slide, a slider, a linkage cylinder, a locking cylinder, and a pressure block, the slider, the linkage cylinder and the locking cylinder are all installed on the slide, and the slide is slidably installed on the guide rail through the slider; the electromagnetic valve box is installed with electromagnetic valves corresponding to each cylinder.

[0007] Furthermore, the slides are provided in plurality and are provided on both sides of the frame 1 , and the slides are provided as an upper pressure belt slide and a lower pressure belt slide, and the upper pressure belt slide and the lower pressure belt slide are symmetrically provided.

[0008] Furthermore, the linkage cylinder of the upper pressing belt slide seat presses the upper belt of the annular synchronous belt when extending.

[0009] Furthermore, when the linkage cylinder of the downward pressing belt slide seat is extended, the lower belt of the annular synchronous belt is pressed.

[0010] The ranking method of the technical solution is as follows, which comprises the following steps:

[0011] A. Determine the number of stations n required, and slide the extra slide to one end and lock it;

[0012] B. Establish a coordinate system with the center line of the equipment as the absolute 0 position, and then calculate the absolute position X1-X of each station in this coordinate system according to the settings. n ;

[0013] C. Detect the distance Z1-Z between the current position of each slide and the center line n ;

[0014] D. Calculate the distance each slide needs to move S1-S n ;

[0015] E. Adjust the distance between the slides. First, move the slides in one direction and lock them in the set position. If there is an obstacle during the movement, stop. If it has not reached the position, proceed to step F.

[0016] F. The slide that has not reached the set position slides in the other direction, and stops and locks when it reaches the set position; when checking whether all have reached the set position, if any have not reached the set position, jump to step E until all have reached the set position.

[0017] The technical solution includes a frame part and a slide part, and the slide part is connected to the frame part, wherein: the frame part includes: a guide rail beam, a guide rail, a synchronous belt, a servo motor, a synchronous pulley, and a solenoid valve box. The guide rail, the servo motor and the synchronous pulley are all installed on the guide rail beam, the synchronous belt is wrapped around the synchronous pulley, and the servo motor drives the synchronous belt to rotate through the synchronous pulley; the slide part includes a slide, a slider, a linkage cylinder, a locking cylinder, and a pressure block. The slider, the linkage cylinder and the locking cylinder are all installed on the slide, and the slide is slidably installed on the guide rail through the slider; the solenoid valve box is installed with a solenoid valve corresponding to each cylinder. The guide rail 102, the servo motor 104 and the synchronous pulley 105 are all installed on the guide rail beam 101, the synchronous belt 103 is wrapped around the synchronous pulley 105, and the servo motor 104 drives the synchronous belt 103 to rotate through the synchronous pulley 105. The solenoid valve box 106 is installed with a solenoid valve corresponding to each cylinder. The slider 202, the linkage cylinder 203 and the locking cylinder 204 are all installed on the carriage 201, and the carriage 201 is slidably installed on the guide rail 102 through the slider 202. When the linkage cylinder 203 is extended and the locking cylinder 204 is retracted, the slide 2 is pressed on the synchronous belt 103 through the pressing block 205 and is separated from the guide rail beam 101. At this time, the slide 2 can move with the synchronous belt 103 and can be accurately positioned to the target position by the servo motor 104; when the linkage cylinder 203 is retracted and the locking cylinder 204 is extended, the slide 2 is separated from the synchronous belt 103 and locked on the guide rail beam 101 at the same time. At this time, the position of the slide 2 can be locked, that is, the slide 2 can be fixed and maintained at the target position.

[0018] In this technical solution, the slide 2 is divided into two types: an upper pressing belt slide U2 and a lower pressing belt slide D2. The difference is that when the linkage cylinder 203 of the upper pressing belt slide U2 is extended, it presses the upper belt of the annular synchronous belt 103, and when the linkage cylinder 203 of the lower pressing belt slide D2 is extended, it presses the lower belt of the annular synchronous belt 103. There are several slides of the two types and they are arranged on both sides of the frame 1. Since the upper belt and the lower belt of the annular synchronous belt will move symmetrically towards each other at the same time when the synchronous belt 103 rotates, the corresponding slides U2 and D2 on the left and right sides respectively pressed on the upper belt and the lower belt of the synchronous belt 103 can be arranged symmetrically at the same time.

[0019] In the production process of corrugated cardboard production line, due to the process requirements, multiple stations need to orderly arrange multiple groups of workpieces. Manual arrangement relies on manual movement of workpieces to the working position, which is time-consuming and labor-intensive, inefficient and inaccurate, and has safety hazards. Large automatic arrangement mechanisms cannot be used due to their large size and complex structure, and are restricted by factors such as small installation space and harsh working environment. This automatic arrangement mechanism uses a servo motor for automatic positioning, and the arrangement is fast and accurate. The mechanism is small in size, simple in structure, easy to operate and maintain. It overcomes the disadvantages of manual operation and is suitable for most working environments, which can greatly improve production efficiency. This automatic arrangement mechanism can be applied to various station occasions in the production of corrugated cardboard production line. The slide 2 of this arrangement mechanism is reserved with a workpiece installation position, and various workpieces can be installed, thereby realizing multiple uses. For example: after installing the pre-pressing wheel device used by the longitudinal cutting and creasing machine, the pre-pressing wheel of the longitudinal cutting and creasing machine can be automatically arranged; after installing the threading and breaking device of the threading machine, the threading machine can be automatically arranged; and so on.

[0020] This automatic sorting mechanism uses a servo motor for automatic positioning, with rapid sorting, controllable precision, small size, simple structure, easy operation and maintenance, which overcomes the disadvantages of manual operation and is suitable for most working environments.

DETAILED DESCRIPTION

[0030] Now, the preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0031] Embodiment 1:

[0032] An automatic ranking mechanism includes a frame part and a slide part, and the slide part is connected to the frame part, wherein: the frame part 1 includes: a guide rail beam 101, a guide rail 102, a synchronous belt 103, a servo motor 104, a synchronous pulley 105, and a solenoid valve box 106, the guide rail 102, the servo motor 104 and the synchronous pulley 105 are all installed on the guide rail beam 101, the synchronous belt 103 is wrapped around the synchronous pulley 105, and the servo motor 104 drives the synchronous belt 103 to rotate through the synchronous pulley 105; the slide part 2 includes: a slide, a slider 3, a linkage cylinder, a locking cylinder 7, and a pressure block, the slider 3, the linkage cylinder and the locking cylinder 7 are all installed on the slide, and the slide is slidably installed on the guide rail 102 through the slider 3; the solenoid valve box 106 is installed with a solenoid valve corresponding to each cylinder. The slides are provided in a plurality and are arranged on both sides of the frame 1. The slides are provided so that the linkage cylinder of the upper pressing belt slide extends to press the upper belt of the annular synchronous belt. The linkage cylinder includes an upper pressing belt cylinder 401 and a lower pressing belt cylinder 501, and the pressing block includes an upper pressing block 402 and a lower pressing block 502.

[0033] Embodiment 2:

[0034] The difference between this embodiment and embodiment 1 is that the slide seat in this embodiment is configured as a lower pressure belt slide seat, and the linkage cylinder of the lower pressure belt slide seat presses the lower belt of the annular synchronous belt when it is extended.

[0035] Embodiment 3:

[0036] This embodiment is an automatic ranking method, which includes the following steps:

[0037] A. Determine the number of stations n required, and slide the extra slide to one end and lock it;

[0038] B. Establish a coordinate system with the center line of the equipment as the absolute 0 position, and then calculate the absolute position X1-X of each station in this coordinate system according to the settings. n ;

[0039] C. Detect the distance Z1-Z between the current position of each slide and the center line n ;

[0040] D. Calculate the distance each slide needs to move S1-S n ;

[0041] E. Adjust the distance between the slides. First, move the slides in one direction and lock them in the set position. If there is an obstacle during the movement, stop. If it has not reached the position, proceed to step F.

[0042] F. The slide that has not reached the set position slides in the other direction, and stops and locks when it reaches the set position; then check whether all have reached the set position, and if not, jump to step E until all have reached the set position.

[0043] Embodiment 4:

[0044] The difference between this embodiment and embodiment 3 is that this embodiment takes 8 slides as an example, as shown in the figure, and now requires slides 1 to 8 to be arranged to workstations 1 to 8 respectively. The specific calculation process and arrangement steps are as follows:

[0045] Establish a coordinate system with the center line of the equipment as the absolute 0 position, and then calculate the absolute positions X1 to X8 of stations 1 to 8 in this coordinate system according to the order or ranking requirements;

[0046] Since the initial positions Z1 to Z8 of slides 1 to 8 are the slide zero positions or the positions positioned after the last order placement, they are known.

[0047] In order to save time to the maximum extent, the following principles are followed when arranging: 1. Move the adjacent slides to the required spacing first and then move them into place uniformly; 2. Move the slide that needs to be moved to the right first and then the slide that needs to be moved to the left; 3. Move the unobstructed slide first and then move the remaining slides in sequence; 4. When arranging, the slide that needs to be moved enters the linkage state and the slide that does not need to be moved enters the locked state. Based on this principle, the required moving steps and the slides and distances moved each time can be calculated:

[0048] Move Steps Slider movement direction Moving slider Moving distance Step 1 right Slider 4 S4=(X4-X3)-(Z4-Z3) Step 2 right Slider 4, 3 S3=(X3-X2)-(Z3-Z2) Step 3 right Sliders 4, 3, 2 S2=(X2-X1)-(Z2-Z1) Step 4 right Slider 4, 3, 2, 1 S1=X1-Z1 Step 5 Left Slider 5 S5=(X6-X5)-(Z6-Z5) Step 6 Left Sliders 5 and 6 S6=(X7-X6)-(Z7-Z6) Step 7 Left Sliders 5, 6, 7 S7=(X8-X7)-(Z8-Z7) Step 8 Left Sliders 5, 6, 7, 8 S8=Z8-X8

[0049] When arranged symmetrically, workstations 1 to 4 and workstations 8 to 5 are symmetrical with respect to the center line, and the initial positions of slides 1 to 4 and slides 8 to 5 are also symmetrical with respect to the center line, so the moving distance S1 to S4 and the moving distance S8 to S5 are equal to each other, that is, S1=S8, S2=S7, S3=S6, S4=S5. As introduced in the working principle, slides 1 to 4 are the lower pressure belt slides, and slides 5 to 8 are the upper pressure belt slides. After entering the linkage state, when the synchronous belt rotates in the same direction, the slides on the left and right sides will move symmetrically towards each other at the same time. Because the distances S1=S8, S2=S7, S3=S6, S4=S5 are symmetrically arranged, so when executing step 1, slides 4 and 5 can enter the linkage state at the same time, and then the synchronous belt rotates counterclockwise by a distance of S4 (S5=S4). In this way, the synchronous belt only needs to rotate once, that is, the moving step only needs to be executed once, and slides 4 and 5 can be moved into place. Similarly, all corresponding steps of moving to the left and right can be combined into one time, so that all slides can be moved into place in half the time:

[0050] Move Steps Moving slider Moving distance Step 1 Sliders 4 and 5 S4=(X4-X3)-(Z4-Z3) Step 2 Sliders 4, 3, 5, 6 S3=(X3-X2)-(Z3-Z2) Step 3 Sliders 4, 3, 2, 5, 6, 7 S2=(X2-X1)-(Z2-Z1) Step 4 Sliders 4, 3, 2, 1, 5, 6, 7, 8 S1=X1-Z1

For those skilled in the art, as long as there is no structural conflict, the technical solutions recorded in the above embodiments can be modified, or some of the technical features therein can be replaced by equivalents; and all these modifications and replacements should fall within the scope of protection of the claims attached to the present invention.
