Description

Technical Field

[0001] This utility model relates to the field of packaging equipment technology, and in particular to a double-sided changing device for an automated production line. Background Technology

[0002] In the packaging industry, automated production lines, especially conveyor lines, are equipped with double-sided guardrails on both sides of the conveying direction for protection. When the same production line conveys products of different sizes, especially those with different widths, the original spacing between the double-sided guardrails may affect the conveying of products. Therefore, it is necessary to adjust the distance between the double-sided guardrails and change the width between them, which is called double-sided remodeling of the production line.

[0003] like Figure 1 As shown, currently, guardrail 2 is installed using a manual adjustment mechanism 3, which adjusts the horizontal position of guardrail 2 to achieve the width adjustment between the two guardrails 2. When a changeover is required on both sides of production line 1, the manual adjustment mechanism 3 on the guardrail 2 needs to be manually adjusted. For one guardrail 2, multiple manual adjustment mechanisms 3 are often required for support, so they need to be adjusted one by one. This makes the adjustment process cumbersome, time-consuming, and results in low precision, making it difficult to meet the requirements of current rapid production. Utility Model Content

[0004] This utility model provides a double-sided changeover device for an automated production line. It uses a servo motor to control the changeover module to achieve automatic and rapid double-sided changeover on the production line. It is simple to operate, has high changeover accuracy and high changeover efficiency, and improves both production efficiency and the automation level of the equipment.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a double-sided type-changing device for an automated production line, comprising multiple quick-change modules arranged along the conveying direction of the production line, a transmission connecting rod for connecting multiple quick-change modules in series, and a servo motor.

[0006] The quick changeover module includes a module housing, a left support and a right support mounted on the module housing that can move simultaneously toward or away from each other. The left support is connected to the guardrail on the left side of the production line, and the right support is connected to the guardrail on the right side of the production line. The left support and the right support are respectively connected to a lead screw drive mechanism, and the lead screw in the lead screw drive mechanism is connected to a transmission mechanism. One end of the transmission mechanism in the quick changeover module located at one end is connected to a servo motor, and the other end is connected to the transmission connecting rod. The transmission mechanisms of adjacent quick changeover modules are connected to each other through the transmission connecting rod.

[0007] Furthermore, the left and right supports are respectively connected to the lead screw drive mechanism via sliders.

[0008] Furthermore, the lead screw drive mechanism includes a lead screw and a nut assembly. The lead screw is provided with a left-hand thread and a right-hand thread. The nut assembly includes a left-hand nut assembly and a right-hand nut assembly. The left-hand nut assembly engages with the left-hand thread of the lead screw, and the right-hand nut assembly engages with the right-hand thread of the lead screw. Both the left-hand nut assembly and the right-hand nut assembly are connected to corresponding sliders, driving the left support and the right support to move.

[0009] Furthermore, a left mounting plate is fixed to the upper end of the left bracket for connecting the guardrail on the left side of the production line; a right mounting plate is fixed to the upper end of the right bracket for connecting the guardrail on the right side of the production line.

[0010] Furthermore, the left bracket is provided with two symmetrically arranged arms side by side, with multiple connecting rods connecting the two arms, and the upper end of each arm is provided with the left mounting plate.

[0011] Furthermore, the right bracket is provided with two symmetrically arranged arms side by side, with multiple connecting rods connecting the two arms, and the upper end of each arm is provided with the right mounting plate.

[0012] Furthermore, the transmission mechanism is a bevel gear set, the input side of which has two connecting ends, one of which is connected to the transmission connecting rod, and the other connecting end is connected to the transmission connecting rod or the output shaft of the servo motor. The output side of the bevel gear set is connected to the lead screw.

[0013] Furthermore, the bevel gear set is connected to the lead screw, transmission connecting rod, and output shaft of the servo motor via couplings.

[0014] The beneficial effects achieved by this utility model are as follows: This device adopts a servo motor-controlled quick change module to realize bilateral automatic quick change of change components. The cooperation between the servo motor and the lead screw drive mechanism has the advantages of simple operation, high change accuracy, and high change efficiency. While improving production efficiency, it also improves the automation level of the equipment and realizes diversified production of the production line. Different products can achieve bilateral automatic quick production switching between different specifications of products through efficient change methods.

[0015] This device can be applied not only to the design and manufacturing of new equipment, but also to the transformation of old production lines. It greatly shortens changeover time, makes changeover more accurate, and significantly improves productivity. At the same time, the automation level of the equipment is also greatly improved, reducing labor costs and increasing enterprise efficiency. Attached Figure Description

[0023] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0024] Example 1

[0025] like Figure 3 As shown, a double-sided changeover device for an automated production line includes quick-change modules 7 spaced apart along the production line 1, transmission connecting rods 6 that drive each quick-change module 7 to move synchronously, and a servo motor 5. Guardrails 2 on both sides of the production line 1 are respectively connected to the top of the quick-change modules 7. The two ends of the transmission connecting rods 6 are respectively connected to two adjacent quick-change modules 7. The output shaft of the servo motor 5 is connected to an adjacent quick-change module 7, thereby driving each quick-change module 7 to move synchronously through multiple transmission connecting rods 6, adjusting the distance between the two connected guardrails 2, and completing the quick-change.

[0026] The following combination Figure 4 , 5A more detailed explanation of the structure and principle of the quick changeover module 7.

[0027] like Figure 4 As shown, the quick changeover module 7 includes a module housing 701, a left support 702, a right support 703, and a transmission mechanism 706. A linear track is provided on the upper part of the module housing 701, and two sliders are slidably mounted on the linear track. The lower ends of the left support 702 and the right support 703 are respectively fixedly connected to one slider. A left mounting plate 704 is fixed to the upper part of the left support 702, and a right mounting plate 705 is fixed to the upper part of the right support 703. The left mounting plate 704 is used to fix the guardrail 2 on the left side of the production line 1 with screws, and the right mounting plate 705 is used to fix the guardrail 2 on the right side of the production line 1 with screws. A drive mechanism is also provided inside the module housing 701. The drive mechanism drives the left support 702 and the right support 703 to move towards or away from each other through the two sliders, thereby adjusting the distance between the two guardrails 2. The drive mechanism is connected to the transmission mechanism 706 at one end of the module housing 701. The transmission mechanisms 706 of adjacent modules are connected by the transmission connecting rod 6. Thus, after the servo motor 5 is started, it can drive the left support 702 and the right support 703 in each quick change module 7 to move synchronously, so as to prevent the guardrail 2 from twisting during the adjustment process.

[0028] To further improve the fixing effect of the guardrail 2, the left bracket 702 is provided with two symmetrically arranged arms side by side, connected by a connecting rod to enhance the overall strength and torsional resistance. Each arm has a left mounting plate 704 at its upper end, with two screw holes. The right bracket 703 uses the same structure with a right mounting plate 705. Thus, both the left bracket 702 and the right bracket 703 can be fixedly connected to the guardrail 2 using four screws.

[0029] like Figure 5 As shown, the drive mechanism within the module housing 701 includes a lead screw 707 and a nut assembly mounted on the lead screw 707. The lead screw 707 is rotatably supported within the module housing 701. The lead screw 707 has left-hand and right-hand threads. The nut assembly includes a left-hand nut assembly 708 and a right-hand nut assembly 709, which are respectively fixed to the two sliders. The left-hand nut assembly 708 engages with the left-hand thread on the lead screw 707, and the right-hand nut assembly 709 engages with the right-hand thread on the lead screw 707. By rotating the lead screw 707, the left support 702 and the right support 703 can drive the connected guardrail 2 to move simultaneously towards or away from each other, thereby adjusting the width of the double-sided guardrail.

[0030] The axial direction of the lead screw 707 is perpendicular to the axial direction of the transmission connecting rod 6. To achieve transmission, one end of the lead screw 707 extends from the end of the module housing 707 and is connected to the transmission mechanism 706 via a coupling. The transmission mechanism 706 is used to achieve reversing transmission. In this embodiment, the transmission mechanism 706 includes a bevel gear set composed of two bevel gears meshing perpendicularly. The two bevel gears of the bevel gear set are respectively mounted on a vertically arranged power input shaft and power output shaft. The two ends of the power input shaft are respectively connected to two transmission connecting rods 6 or to the output shaft of the servo motor 5 via couplings. The power output shaft is connected to the lead screw 707 via a coupling. The power of the servo motor 5 is transmitted to each bevel gear set via the transmission connecting rod 6, and then transmitted to the connected lead screw 707 after reversing, thereby realizing the drive of the left support 702 and the right support 703 by the lead screw 707. The structure of the bevel gear set is a conventional transmission component in the mechanical field, and the implementer can select and use it according to the design requirements.

[0031] For example Figure 2 As shown, when the double-sided changing device 4 of this utility model is installed on the production line 1, the quick changing module 7 is located below the production line 1 and fixed on the adjacent production line frame. The left support 702 and the right support 703 are located on the left and right sides of the production line 1, and the upper ends of the left support 702 and the right support 703 are higher than the conveying surface of the production line 1, so that the connected guardrail 2 is higher than the conveying surface of the production line 1 and located on the left and right sides of the conveying surface.
