Description

Technical Field

[0001] The utility model relates to the field of sandwich panel production lines, and is particularly suitable for a sandwich panel production line. Background Art

[0002] The continuous production process of composite panels such as metal-faced polyurethane sandwich panels, metal-faced rock wool sandwich panels, metal-faced glass wool sandwich panels, and metal-faced polystyrene sandwich panels requires spraying adhesive or foaming materials, and then aging through double crawlers to ensure bonding strength and surface flatness of the sandwich panels. After aging, the sandwich panels enter the cutting device and are cut to a customized length. After continuous cutting, only the tail plate of the sandwich panel remains in the double crawlers. Since the tail plate part is too short, the double crawlers have almost no driving force on the sandwich panel, and it is difficult to push the tail plate into the cutting equipment through the friction of the double crawlers themselves. Usually, the double crawlers can only be opened by lifting the upper crawler, and then the tail plate of the sandwich panel is manually pushed into the cutting equipment, and the cutting system is manually controlled for cutting.

The embodiments of the present utility model are described in detail below in conjunction with the drawings.

[0026] It should be understood that the drawings are only used to illustrate the present application.

[0027] A sandwich panel production line, such as Figure 1-4 As shown, it includes a conveying device for conveying sandwich panels 7, a pushing device for receiving sandwich panels 7 sent out by the conveying device, and a processing device for receiving sandwich panels 7 sent out by the conveying device or the pushing device. The processing device performs processing operations on the sandwich panels 7. The conveying device, the pushing device, and the processing device are sequentially arranged along the conveying direction of the sandwich panels 7. The length of the sandwich panels 7 is usually long, so the sandwich panels 7 can be divided into a head panel and a tail panel. When the head panel is separated from the conveying device, the tail panel may not be separated from the conveying device. At this time, the head panel passes through the pushing device and the processing device in sequence, but even if the head panel of the sandwich panel 7 has been processed at the processing device, the tail panel may still be conveyed at the conveying device. The conveying device can be set as any device that can convey the sandwich panels 7. In this solution, the conveying device is set as a double crawler 5; the processing device can be set as any device that processes the sandwich panels 7. In this solution, the processing device is set as a cutting device 6.

[0028] like Figure 2-Figure 4 As shown, the pushing device includes a base 1, a clamping module arranged on the base 1, and a pressure sensor 51 arranged on the double crawler 5, and the clamping module includes a relaxed state without interference with the sandwich panel 7 and a clamping state for clamping the sandwich panel 7. When the pressure sensor 51 detects that the pressure of the double crawler 5 is a normal value, the clamping module is in a relaxed state, and when the pressure sensor 51 detects that the pressure of the double crawler 5 is less than the normal value, the clamping module is in a clamping state.

[0029] The base 1 is fixed between the double crawler 5 and the cutting device 6 by expansion bolts. The base 1 is mainly used to fix the clamping assembly. The base 1 includes a base bracket and support rods arranged at both ends of the base bracket. There is no obstruction between the two support rods, which is convenient for the sandwich panel 7 to pass through.

[0030] The clamping module includes a lower clamping roller assembly arranged on the base 1 and an upper pressing wheel assembly that can approach or move away from the lower clamping roller assembly.

[0031] The upper pressure wheel assembly includes a slide rail 22 arranged on the base 1, a slider 23 arranged on the slide rail 22, an upper pressure wheel 25 arranged on the slider 23, and a cylinder 21 that drives the slider 23 to move on the slide rail 22, and the cylinder 21 drives the slider 23 to move on the slide rail 22 in the direction close to or away from the lower clamping roller assembly. The upper pressure wheel 25 is made of hollow elastic material, which ensures the friction force on the sandwich panel 7 while ensuring that the pressure is stable and small, thereby reducing the deformation damage that the pressure may cause to the surface of the sandwich panel 7. The slide rail 22 is arranged on the support rod, and the slide rail 22 is arranged on both of the support rods. The slide rail 22 is arranged vertically and in parallel, so that the upper pressure wheel 25 can move in the direction close to or away from the lower clamping roller assembly. The length of the slide rail 22 needs to ensure that the upper pressure wheel 25 and the lower clamping roller 32 can clamp the sandwich panel 7 and have no interference with the sandwich panel 7. Slide blocks 23 are provided on both of the slide rails 22, and the upper pressure wheel 25 can be directly connected to the slide blocks 23. However, if the size of the sandwich panel 7 changes, it may not be possible to clamp the sandwich panel 7. Therefore, in this solution, a pressure wheel connecting rod 24 is provided to connect the two slide blocks 23, and the upper pressure wheel 25 is provided on the pressure wheel connecting rod 24. The upper pressure wheel 25 can be provided at any position of the pressure wheel connecting rod 24, but in order to ensure the clamping of sandwich panels 7 of different sizes, the upper pressure wheel 25 is provided at the middle position of the pressure wheel connecting rod 24 as much as possible. A pressure wheel seat is provided on the pressure wheel connecting rod 24, and the upper pressure wheel 25 is provided on the pressure wheel seat. At least one upper pressure wheel 25 is provided, and the axes of all the upper pressure wheels 25 are located on the same horizontal line. However, in order to ensure the clamping of the sandwich panel 7, in this scheme, four upper pressure wheels 25 are provided, and the four upper pressure wheels 25 are arranged in groups of two, and are evenly provided on the pressure wheel connecting rod 24, and the axes of the four upper pressure wheels 25 are located on the same horizontal line. Both of the two sliders 23 are connected to the cylinder 21, and the two cylinders 21 run synchronously to ensure the stability of the movement of the upper pressure wheel 25, and the cylinder 21 is fixed on the bracket of the base 1.

[0032] The lower clamping roller assembly includes a lower clamping roller 32 arranged on the base 1 and a servo motor 31 connected to the lower clamping roller 32. A bearing seat is arranged on the base 1, and a bearing is arranged on the bearing seat. The lower clamping roller 32 is connected to the bearing. The servo motor 31 drives the lower clamping roller 32 to rotate in the bearing. Two bearing seats are arranged, and the two bearing seats are arranged at both ends of the base bracket. The two ends of the lower clamping roller 32 are respectively connected to the two bearings. The servo motor 31 can adjust the rotation speed of the lower clamping roller 32 as needed. The continuous production line provides a speed signal to the servo motor 31, so that the rotation speed of the lower clamping roller 32 is synchronized with the production line speed, thereby accurately calculating the forward distance of the sandwich panel 7, facilitating automatic cutting of the cutting device, saving repeated measurement of the board length and marking time, improving efficiency, and making the size more accurate. In order to ensure that the upper pressure wheel 25 cooperates with the lower clamping roller 32 to clamp the sandwich panel 7 well, the axis of the lower clamping roller 32 and the upper pressure wheel 25 are on the same vertical line. A reduction gear unit 33 is provided between the lower clamping roller 32 and the servo motor 31 .

[0033] When the pressure sensor 51 detects that the pressure of the double track 5 is less than the normal value, the upper pressure wheel 25 moves to the lower clamping roller 32 and clamps the sandwich panel 7. However, after the sandwich panel 7 is transported, the upper pressure wheel 25 is easy to collide with the lower clamping roller 32. Therefore, after the sandwich panel 7 is transported, the upper pressure wheel 25 needs to move away from the lower clamping roller 32. Therefore, a photoelectric sensor 42 for detecting the sandwich panel 7 is provided on the base 1. When the photoelectric sensor 42 cannot detect the sandwich panel 7, the cylinder 21 drives the upper pressure wheel 25 to move away from the lower clamping roller 32. The sandwich panel 7 first passes through the clamping module and then passes through the photoelectric sensor 42 to prevent the cylinder 21 from driving the upper pressure wheel 25 to move away from the lower clamping roller 32 after the photoelectric sensor 42 cannot detect the sandwich panel 7, and the sandwich panel 7 cannot be clamped. The clamping module can be set on the side of the base 1 close to the double tracks, and the photoelectric sensor 42 can be set on the side of the base 1 away from the double tracks. However, in this case, it is easy to cause the sandwich panel 7 to be transported, and the clamping module is still in the clamping state, and the upper pressure wheel 25 and the lower clamping roller 32 are easy to collide; the clamping module and the photoelectric sensor 42 can also be set on the side of the base 1 close to the double tracks 5, but in this case, in order to ensure that the sandwich panel 7 passes through the clamping module first and then the photoelectric sensor 42, the photoelectric sensor 42 needs to be set at a position closer to the base 1, which is inconvenient to set; therefore, in this scheme, the clamping module and the photoelectric sensor 42 are both set on the side of the base 1 away from the double tracks, which is convenient to set, ensuring the full clamping of the sandwich panel 7, and preventing the upper pressure wheel 25 from continuing to move downward due to the action of the cylinder 21 and colliding with the lower clamping roller 32.

[0034] A sensor bracket 41 is arranged on the base 1, and the sensor bracket 41 is located in the middle of the length direction of the lower clamping roller 32; the photoelectric sensor 42 is arranged on the sensor bracket 41, and the photoelectric sensor 42 can move on the sensor bracket 41 toward or away from the clamping module. In this solution, the straight-line distance between the photoelectric sensor 42 and the lower clamping roller 32 is 200 to 600 mm, which can ensure that the upper pressing wheel 25 and the lower clamping roller 32 clamp the sandwich panel throughout the whole process, and can also ensure that the upper pressing wheel 25 and the lower clamping roller 32 are separated as soon as possible to avoid collision.

[0035] The clamping module includes a clamping state and a relaxing state. In the clamping state, the upper pressure wheel 25 moves toward the lower clamping roller 32 until it clamps the sandwich panel 7. The sandwich panel 7 is sent to the cutting device through the clamping force of the upper pressure wheel 25 and the lower clamping roller 32 on the sandwich panel 7, and the rotation speed of the lower clamping roller 32 can be set to be consistent with the speed of the production line through the servo motor 31 to ensure the accurate cutting length of the sandwich panel 7; in the relaxing state, the upper pressure wheel 25 moves away from the lower clamping roller 32 until it returns to its original position, and the sandwich panel 7 can pass through the pushing device. At this time, the pushing device has no interference with the sandwich panel 7.

[0036] The sandwich panel 7 has a certain length. Under normal circumstances, the double crawler 5 clamps the sandwich panel 7. At this time, the double crawler 5 has a clamping force on the sandwich panel 7, and the sandwich panel 7 can be smoothly pushed into the cutting device for cutting. At this time, the pushing device is in a relaxed state, and the pushing device has no interference with the sandwich panel 7. The sandwich panel 7 can move from the lower clamping roller 32 when passing through the pushing device and smoothly enter the cutting device 6. After the cutting device 6 continues to cut the sandwich panel 7, the length of the sandwich panel 7 is not enough to support the clamping force of the double crawler 5 on the sandwich panel 7, and the sandwich panel 7 may not be able to complete the transportation. When the pressure sensor 51 detects that the pressure is less than the normal value, the pushing device changes from a relaxed state to a clamping state, and the upper pressure wheel 25 moves in a direction close to the lower clamping roller 32 until the sandwich panel 7 is clamped, and the clamping force is applied to the sandwich panel 7, and the sandwich panel 7 is continuously sent into the cutting device 6 to ensure the cutting and transportation of the tail plate of the sandwich panel 7. The rotation speed of the lower clamping roller 32 is consistent with the production line to ensure the accuracy of the cutting.

[0037] The specific operation method of the sandwich panel production line is as follows:

[0038] The base 1 is fixed between the double crawler 5 and the cutting device 6 by expansion bolts. The double crawler 5 clamps the sandwich panel 7 and transports the sandwich panel 7 to move. When the pressure sensor 51 detects that the pressure of the double crawler 5 is a normal value, the conveying device maintains the initial state, and the cutting device 6 receives the sandwich panel 7 sent from the double crawler 5 and cuts the sandwich panel 7; when the pressure sensor 51 detects that the pressure of the double crawler 5 is less than the normal value, the pressure sensor 51 transmits the signal to the servo motor 31 and the cylinder 21. After receiving the signal, the cylinder 21 drives the upper pressure wheel 25 to move along the slide rail 22 toward the lower clamping roller 32 until the sandwich panel 7 is clamped. After receiving the signal, the servo motor 31 starts working and drives the lower clamping roller 32 to move. The roller 32 rotates synchronously with the speed of the production line. The tail plate of the sandwich panel 7 continues to move at the speed of the production line under the clamping and pushing friction between the upper pressure wheel 25 and the lower clamping roller 32. After entering the cutting device 6, the sandwich panel 7 is cut while maintaining a stable position due to the clamping force. When the photoelectric sensor 42 cannot detect the sandwich panel 7, the signal is transmitted to the servo motor 31 and the cylinder 21. After receiving the signal, the cylinder 21 drives the upper pressure wheel 25 to move along the slide rail 22 away from the lower clamping roller 32 until there is no interference with the sandwich panel 7, but generally it is the highest position of the slide rail 22. After receiving the signal, the servo motor 31 stops working until the pressure sensor 51 detects again that the pressure of the double track 5 is less than the normal value.

[0039] The utility model mainly designs a sandwich panel production line, and sets a pressure sensor 51 to monitor whether the double track 5 still has a clamping force on the sandwich panel 7. When the pressure sensor 51 detects that the pressure value is less than the normal value, it means that the double track 5 has no clamping force on the sandwich panel 7. At this time, the clamping module is in a clamping state, clamping the sandwich panel 7 and inserting it into the cutting device 6. When the double track 5 still has a clamping force on the sandwich panel 7, the pressure detected by the pressure sensor 51 is a normal value. At this time, the clamping module is in a relaxed state, and the clamping The holding module has no interference with the sandwich panel 7, and the sandwich panel 7 can directly enter the cutting device 6 through the pushing device. It has a simple structure, is easy to operate, saves manpower, and ensures accuracy. The servo motor 31 is provided to ensure that the speed of the lower clamping roller 32 can be kept consistent with the speed of the production line, which is convenient for cutting the sandwich panel 7 and ensuring the size of the sandwich panel 7. It does not need to be measured manually again, which is convenient and fast. The photoelectric sensor 42 is provided so that after the cutting of the sandwich panel 7 is completed, the conveying device is changed from a clamping state to a loose state to avoid collision between the upper pressure wheel 25 and the lower clamping roller 32.
