Description

Technical Field

[0001] This utility model relates to the field of conveying machinery technology, and in particular to a steering conveying device. Background Technology

[0002] Post-processing of engineered wood panels includes processes such as panel screening, cooling, and stacking. Conveying devices are needed to connect these processes and after stacking. Due to factors such as the layout of equipment and the input / output angles of panels, the conveying process often involves turning the panels, changing their orientation by 90°. This type of turning conveyor typically consists of a roller conveyor mounted on a frame, which conveys in the same direction as the original panel. Below this roller conveyor, a liftable bogie is mounted on the frame. A chain conveyor is installed on this bogie, positioned between the rollers of the original roller conveyor. Initially, the bogie is in a low position, with the chain conveyor's conveying surface lower than that of the roller conveyor. Upon arrival of a panel, the bogie is raised, raising the chain conveyor's conveying surface above that of the roller conveyor. The chain conveyor then lifts the panel and, using its own conveying action, outputs it to the downstream conveyor, achieving the 90° turning conveying purpose. In conventional steering conveyor systems, the bogie's lifting and lowering are driven by multiple drive cylinders. Given that common engineered wood panels are typically 2.4m × 1.2m in size, the conveying surface area of ​​the steering conveyor is large, resulting in a correspondingly large bogie frame. This usually requires six to eight drive cylinders for lifting and lowering. However, in practical use, it has been found that due to factors such as hydraulic line pressure and machining errors in the drive cylinders, the synchronization of the multiple drive cylinders during operation is poor. Consequently, the lifting and lowering of the chain conveyor mechanism is unstable, posing a risk of tipping over when steering and conveying stacks of panels of a certain height. Therefore, it is necessary to improve the lifting and lowering stability of the steering conveyor system, leading to this invention. Utility Model Content

Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Undoubtedly, those skilled in the art will recognize that various modifications can be made to the described embodiments without departing from the spirit and scope of the present invention. Therefore, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.

[0019] like Figure 4 As shown, the steering and conveying device includes a frame 1, on which a roller conveyor mechanism 2 is mounted. Conventionally, the roller conveyor mechanism 2 includes a plurality of conveying rollers 21 mounted on the frame 1 and arranged sequentially along the conveying direction. Inter-roller gaps are provided between adjacent conveying rollers 21, and the conveying rollers 21 are collectively connected to a conveying roller driver 22. A lifting and movable bogie 4 is mounted on the frame 1, and a chain conveyor mechanism 3 is mounted on the bogie 4, located at the roller gaps. This structural arrangement is well-known in the art and will not be described in detail here.

[0020] like Figure 5 As shown, in this embodiment, the bogie 4 includes a bogie base 41 positioned below the roller conveyor mechanism 2. Chain mounting frames 42 are respectively provided on the bogie base 41 at intervals corresponding to the conveyor rollers 21 of the roller conveyor mechanism 2. A support frame 43 is fixedly connected between the chain mounting frame 42 and the bogie base 41. Based on this, as... Figure 1 , Figure 2 and Figure 5 As shown, the chain conveyor mechanism 3 in this embodiment includes upper chain pulleys 31 installed at both ends of the chain mounting frame 42. A chain drive shaft 32 is rotatably mounted on the steering base frame 41. Lower chain pulleys 33 are respectively installed on the chain drive shaft 32 corresponding to each of the chain mounting frames 42. A conveyor chain 34 is installed on the lower chain pulleys 33 and the two corresponding upper chain pulleys 31. A chain driver 35 is provided between the chain drive shaft 32 and the steering base frame 41. With the above structure, the chain conveyor mechanism 3 is set at the intervals of the conveyor rollers 21 of the roller conveyor mechanism 2, and one chain driver 35 drives multiple conveyor chains 34.

[0021] At least two rows of lifting transmission swing arms 5 are arranged side by side on the frame 1, such as Figure 3 As shown, this embodiment only uses two rows for illustration. Figure 1 , Figure 2 and Figure 5As shown, the lifting transmission swing arm 5 includes a lifting section 51 that swings in the pitch direction and a transmission connection section 52 that swings in the arrangement direction, so that each of the lifting transmission swing arms 5 is approximately in the shape of a figure 7. The free end of the lifting section 51 is hinged to the bogie 4, and a linkage rod 6 is hinged between the free ends of adjacent transmission connection sections 52; a lifting driver 7 is installed on the frame 1, and the lifting driver 7 is used to drive the lifting transmission swing arms 5 in each row to move synchronously.

[0022] Through the linkage of each row of linkage rods 6, one lifting driver 7 can drive two rows of lifting transmission swing rods 5 to move synchronously. This can eliminate manufacturing errors of multiple power sources and use rigid structure transmission to make the lifting and lowering section 51 of each lifting transmission swing rod 5 reflect the synchronicity of lifting the bogie 4, thereby improving the stability of lifting.

[0023] like Figure 3 , Figure 4 and Figure 5 As shown, the lifting drive 7 in this embodiment includes a drive synchronous shaft 71 rotatably mounted on the frame 1. A drive eccentric component 72 is fixedly provided on the drive synchronous shaft 71 at each of the rows of lifting transmission swing arms 5. A transmission connecting rod 73 is hinged between the free end of the drive eccentric component 72 and the transmission connection section 52 of the nearest lifting transmission swing arm 5 in the corresponding row. A lifting drive motor 74 is mounted on the frame 1, and the power end of the lifting drive motor 74 is transmittedly connected to the drive synchronous shaft 71.

[0024] After the lifting drive motor 74 drives the drive synchronous shaft 71 to rotate, the drive eccentric component 72 drives all the transmission connecting sections 52 to swing synchronously through the transmission connecting rod 73, thereby achieving a smooth lifting of the bogie 4. Of course, when the lifting drive motor 74 drives the drive synchronous shaft 71 to rotate forward, the bogie 4 is lifted; when the lifting drive motor 74 drives the drive synchronous shaft 71 to rotate in reverse, the lifting transmission swing rod 5 swings in the opposite direction, and the bogie 4 is lowered.

[0025] Therefore, after the roller conveyor 2 receives the input plate, the lifting drive motor 74 drives the drive synchronous shaft 71 to rotate forward, as shown. Figure 1 As shown, the bogie 4 is raised, and the chain conveyor 3 takes over from the roller conveyor 2 to lift the plate and output it to the side. After output, the lifting drive motor 74 drives the drive synchronous shaft 71 to reverse, as shown. Figure 2 As shown, the bogie 4 descends, and the chain conveyor 3 returns to a position where the conveying surface is lower than the conveying surface of the roller conveyor 2. The roller conveyor 2 can receive subsequent input plates.

[0026] Preferably, the linkage rod 6 and the two connected transmission sections 52 form a parallelogram mechanism. Therefore, the lengths of all transmission sections 52 should be equal, and the lengths of all lifting sections 51 should also be equal. Furthermore, this length refers to the length of the centerline between the center of the lifting transmission lever 5 and the center of the hinge axis, not the overall length of each section. All subsequent references to the length of the rod should be understood in this manner.

[0027] Preferably, such as Figure 5 As shown, the linkage rod 6 includes a fisheye rod head 61 that is respectively connected to the two transmission connecting sections 52. Each fisheye rod head 61 is provided with a connecting internal thread, and the threads of the two connecting internal threads are opposite in direction. A linkage main rod body 62 is provided between the two fisheye rod heads 61. Both ends of the linkage main rod body 62 are fixedly provided with connecting studs 63 that are respectively connected to the two fisheye rod heads 61. A rod head fastening nut 64 is installed on each connecting stud 63.

[0028] The fisheye rod head 61 is a known technology and can be either internally threaded or externally threaded; this embodiment uses the internally threaded type. After rotating the rod head fastening nut 64 away from the fisheye rod head 61, the linkage main rod body 62 can rotate relative to the two fisheye rod heads 61. During this rotation, the distance between the two fisheye rod heads 61 changes due to the opposite rotation directions of the two connecting internal threads. The distance between the two fisheye rod heads 61 decreases when rotating in the forward direction and increases when rotating in the reverse direction. This achieves the purpose of adjusting the length of the linkage rod 6, eliminating the influence of machining errors during installation, and forming a parallelogram mechanism with the linkage rod 6 and the two connected transmission connecting sections 52. After adjustment, the rod head fastening nut 64 is rotated back to the position close to the fisheye rod head 61 to lock the length of the linkage rod 6.

[0029] Of course, the transmission link 73 described in this embodiment can also be configured as an adjustable length structure, referring to the linkage 6, to further ensure that the two rows of lifting transmission swing rods 5 swing at the same angle.

[0030] In addition to the above structure, another eccentric component is fixedly installed on the drive synchronous shaft 71. The free end of the eccentric component is hinged to the frame 1 to install a drive cylinder, which can also achieve the purpose of synchronous driving using a single drive power. This method should also be within the protection scope of this utility model.

[0031] In practical use, this embodiment has a relatively large conveying surface area for common plate sizes of 2.4m × 1.2m. Therefore... Figure 4 As shown, in this embodiment, two parallel roller conveyor mechanisms 2 are installed on the frame 1. Figure 1 and Figure 2As shown, the bogies 4 and chain conveyors 3 are respectively installed on the frame 1 at the locations corresponding to the roller conveyors 2. The transmission connection sections 52 of the lifting transmission swing rods 5 near the two bogies 4 are also hinged to the linkage rods 6. Thus, the two parallel roller conveyors 2 can normally receive input plates, and the linkage rods 6 are also hinged between the lifting transmission swing rods 5 between the two bogies 4. One lifting drive motor 74 can drive the two bogies 4 to lift synchronously. Therefore, in this large conveying surface application scenario, this embodiment can better avoid the influence of manufacturing errors of power components and still achieve the effect of improving lifting stability.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
