[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] This invention utilizes two sets of linear slide assemblies. By adjusting the positions of these slides, the overall width of the feeding conveyor belt, the discharging conveyor belt, and the adjusting baffle mechanism can be flexibly adjusted, thereby further increasing the adjustment range of the device.

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0025] Please refer to Figure 1-3 As shown, an embodiment of this application provides a large-size sheet material stacking and conveying device, including a conveying frame 3. A feeding conveyor belt 1 and a discharging conveyor belt 2 are sequentially arranged on the top of the conveying frame 3 along the conveying direction. The feeding conveyor belt 1 is higher than the discharging conveyor belt 2. An adjusting mounting frame 8 is straddling the top of the discharging conveyor belt 2. The fixed side of the adjusting mounting frame 8 is fixedly installed to one side of the discharging conveyor belt 2, and its adjusting side is slidably connected to the opposite side of the discharging conveyor belt 2 and fixed to the conveying frame 3 by fastening bolts. From top to bottom, the fixed or adjusting side of the adjusting mounting frame 8 is sequentially provided with a receiving / discharging mechanism 6 and a transition receiving mechanism 7. Both sets of receiving / discharging mechanisms 6 and the two sets of transition receiving mechanisms 7 are used for conveying... The center of the frame 3 is symmetrically arranged. A lifting receiving mechanism 9 is set at the top of the conveying frame 3 and at the center inside the adjusting mounting frame 8. The conveyed plate material 10 of the feeding conveyor belt 1 enters the space between the two sets of receiving and discharging mechanisms 6 for temporary storage. The plate material 10 is then dropped down by the two sets of receiving and discharging mechanisms 6 and placed between the tops of the two sets of transition receiving mechanisms 7. The top of the lifting end of the lifting receiving mechanism 9 is close to the bottom surface of the plate material 10. After the two sets of transition receiving mechanisms 7 release the plate material 10, the lifting receiving mechanism 9 retracts and drives it to fall to the top surface of the discharge conveyor belt 2. An adjusting blocking mechanism 5 is set at the center of the top of the adjusting mounting frame 8 along its length. The vertical end of the adjusting mounting frame 8 is set close to the front end of the traveling plate material 10.

[0026] The feeding conveyor belt 1 is equipped with a counting sensor 11, and the discharging conveyor belt 2 is equipped with a material receiving sensor 21.

[0027] In a preferred embodiment of this utility model, a pressure roller mechanism 4 is provided near the tail end of the feeding conveyor belt 1. The pressure roller mechanism 4 rolls and presses the top surface of the plate material 10 to increase the transmission force of the feeding conveyor belt 1.

[0028] In a preferred embodiment of the present invention, the counting sensor 11 is further fixedly mounted on the surface of the mounting bracket 43 and close to the top surface of the feed conveyor belt 1.

[0029] In a preferred embodiment of the present invention, the receiving and discharging mechanism 6 further includes two transition cylinders 61. The two transition cylinders 61 are fixedly installed at the bottom of the upper crossbeam 81 and near both ends. A fixed seat 62 is fixedly installed between the ends of the telescopic shafts of the two transition cylinders 61. The fixed seat 62 is connected to a plurality of transition wheels 63 at equal distances along the horizontal direction. The sheet material 10 is placed between the tops of the two rows of transition wheels 63.

[0030] Specifically, such as Figure 1-2 As shown, this conveying device is specifically designed for the process requirements of conveying, stacking and conveying large-area sheet materials 10. By setting counting sensors 11 and material receiving sensors 21 at the feeding conveyor belt 1 and the discharging conveyor belt 2, this device can customize the number of stacking layers by recording the quantity of incoming materials. The material receiving sensor 21 senses and conveys the stacked sheet materials 10 away through the discharging conveyor belt 2, thereby realizing a fully automated production line process for the sheet materials 10.

[0031] In this process, the feeding conveyor belt 1 transmits the sheet material 10 one by one into the receiving and discharging mechanism 6. After being received by the receiving and discharging mechanism 6, the sheet material 10 is placed downward into the transition receiving mechanism 7 for stacking. When the counting sensor 11 records that the number of sheet materials 10 transmitted reaches a preset value, it indicates that the required sheet material 10 has been stacked on the transition receiving mechanism 7. At this time, the lifting receiving mechanism 9 extends upward to hold the bottom of the stacked sheet material 10. After the sheet material 10 is released by the transition receiving mechanism 7, the lifting receiving mechanism 9 retracts to slowly lower the stacked sheet material 10 to the surface of the discharge conveyor belt 2. At this time, the discharge conveyor belt 2 is started by sensing the incoming material sensor 21 to transmit the sheet material 10 in the same direction.

[0032] With the above structural setup, the automatic stacking and automatic transfer of sheet metal 10 can be fully realized. However, in order to match the transfer of large-area, ultra-long sheet metal 10, a special docking and feeding mechanism 6 needs to be designed separately. By installing transition cylinders 61 at both ends of the transverse direction along the transfer direction on the adjusting mounting frame 8, and connecting a fixed seat 62 to the end of the telescopic shaft of the transition cylinder 61, and installing a row of transition wheels 63 on the fixed seat 62, the two rows of transition wheels 63 can support the left and right sides of the sheet metal 10. This structure has no limitation in the length direction of the sheet metal 10 and can be used for connecting and transferring sheet metal 10 of a certain length.

[0033] Meanwhile, the width of the sheet metal 10 can be flexibly adjusted by the extension and retraction of the transition cylinder 61 to match the material, so that the receiving and feeding mechanism 6 can adapt to the transmission function of large sheet metal 10 of various sizes and models.

[0034] Since the front end of the sheet metal 10 in the length direction needs a limiting device to ensure that it can be stably suspended in the receiving and discharging mechanism 6, a set of adjusting blocking mechanism 5 is set at the top center of the adjusting mounting frame 8 to block the sheet metal 10 from moving forward. In order to accommodate different sheet metal 10 sizes, the adjusting blocking mechanism 5 is designed to be adjustable in position for flexible adjustment.

[0035] In addition, the lifting and receiving mechanism 9 consists of multiple sets of lifting and receiving cylinders installed vertically and equidistantly arranged on the conveying frame 3 along the transmission direction. Through the extension of the telescopic shaft of each lifting and receiving cylinder, the pallet set on its top lifts the bottom of the stacked plates 10 in the transition receiving mechanism 7.

[0036] In a preferred embodiment of this utility model, the pressure roller mechanism 4 further includes a mounting bracket 43, which is fixedly mounted to the frame of the feeding conveyor belt 1. A downward pressure cylinder 41 is fixedly mounted on one side of the mounting bracket 43 in the vertical direction. The bottom of the telescopic shaft of the downward pressure cylinder 41 is fixedly mounted to the housing of the downward pressure roller assembly 42. The downward pressure roller assembly 42 is slidably connected to the mounting bracket 43 in the vertical direction. The roller of the downward pressure roller assembly 42 is a rubber wheel.

[0037] Specifically, such as Figure 3 As shown, the downward extension shaft of the downward pressing cylinder 41 drives the downward pressing roller assembly 42 to slide downward on one side of the mounting bracket 43, and the rubber roller presses the top surface of the sheet material 10, thereby increasing the friction between the sheet material 10 and the feeding conveyor belt 1. This allows the sheet material 10 to smoothly enter the receiving and discharging mechanism 6, thus preventing the sheet material 10 from slipping and clogging on the conveyor line and affecting the normal production process, thereby effectively ensuring the efficient transmission function of this device.

[0038] In a preferred embodiment of this utility model, the adjusting mounting frame 8 further includes two adjusting columns 82 and two fixed columns 85. The two fixed columns 85 are spaced apart along the transmission direction and fixedly installed on one side of the conveying frame 3. The two adjusting columns 82 are spaced apart along the transmission direction and fixedly installed on the top surface of the linear slide assembly 84. The linear slide assembly 84 is fixedly installed with the conveying frame 3. Two crossbeams 81 are sequentially fixedly connected between the two adjusting columns 82 or the two fixed columns 85 in the vertical direction. The feeding mechanism 6 is fixedly installed at the bottom of the upper crossbeam 81, and the transition feeding mechanism 7 is fixedly installed at the bottom of the lower crossbeam 81.

[0039] In a preferred embodiment of the present invention, the adjustable side of the discharge conveyor belt 2 is further fixedly installed on the top surface of the linear slide assembly 2 84, and its width is adjusted by the linear slide assembly 2 84.

[0040] The adjustable side of the feed conveyor belt 1 is fixedly installed on the top surface of the linear slide assembly 83, and its width is adjusted by the linear slide assembly 83. The linear slide assembly 83 is fixedly installed with the conveyor frame 3. By adjusting the slide positions of the two sets of linear slide assemblies, the overall width of the feed conveyor belt 1, the discharge conveyor belt 2, and the adjusting baffle mechanism 5 can be flexibly adjusted, thereby further increasing the adjustment range of the device and enabling stacking and conveying of more types of sheet metal 10, thus further increasing the versatility of the device.

[0041] In a preferred embodiment of this utility model, the transition receiving mechanism 7 further includes two pre-receiving cylinders 71, which are fixedly installed at the bottom of the lower crossbeam 81 and near both ends. A pre-receiving baffle 72 is fixedly installed between the ends of the telescopic shafts of the two pre-receiving cylinders 71. The sheet material 10 is placed between the tops of the two pre-receiving baffles 72. The working principle of the transition receiving mechanism 7 is basically the same as that of the receiving and discharging mechanism 6. It is used to receive, stack, and temporarily store the sheet material 10 thrown down by the receiving and discharging mechanism 6 one by one. After the sheet material is stacked to a specified number of layers, it is dragged down to the discharge conveyor belt 2 by the lifting receiving mechanism 9 to continue the transmission.

[0042] In a preferred embodiment of this utility model, the adjusting baffle mechanism 5 further includes a baffle slide rail 51, which is fixedly installed on the top of the adjusting mounting bracket 8. A baffle slider 52 is slidably connected to the top of the baffle slide rail 51, and a transition baffle 53 is fixedly installed on the top of the baffle slider 52. The transition baffle 53 is T-shaped, and the vertical surface of the transition baffle 53 is located downstream of the material receiving and discharging mechanism 6 in the transmission direction.

[0043] Specifically, such as Figure 1As shown, the distance between the transition baffle 53 and the material receiving and discharging mechanism 6 is changed by the sliding of the baffle slider 52 on the surface of the baffle slide rail 51. This allows for temporary blocking of plates 10 of different lengths. After adjustment, the transition baffle 53 is fixed in position by the transition slider and the transition slide rail. The adjustment is flexible and convenient, thus complementing the overall adjustment function of the device.

[0044] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
