Description

Technical Field

[0001] The utility model relates to a bamboo strip shape sorting machine, in particular to an automatic unloading device for the bamboo strip shape sorting machine. Background Art

[0002] The production of bamboo products requires a series of processing steps, including splitting, screening, primary planing, and secondary planing. Splitting involves slicing the bamboo axially into strips; screening involves selecting those that meet various production standards from these strips. Existing screening processes often rely on manual visual inspection, which not only has a high error rate but also relies heavily on worker experience.

[0003] For this purpose, the applicant previously applied for a patent title: A bamboo strip shape sorting machine (patent number: ZL2021204067881, authorization publication date: 2021-11-12), which includes: a detection device, the detection device includes a bamboo strip inlet and a bamboo strip outlet, a transmission wheel shaft is arranged between the bamboo strip inlet and the bamboo strip outlet, and a shape detection mechanism is arranged on the upper side between the bamboo strip inlet and the bamboo strip outlet, and the shape detection mechanism includes a thickness detection mechanism and a width detection mechanism; a conveying device, which is arranged on one side of the bamboo strip outlet; a plurality of extraction devices, arranged along the transmission direction of the conveying device; a control system, including a PLC, for receiving the signal of the shape detection mechanism and grading the bamboo strips, and then controlling the corresponding extraction device to select the bamboo strips to the corresponding workstation. This bamboo strip grade sorting and storage method is achieved by using a plurality of extraction devices. Although the plurality of extraction devices can extract bamboo strips of different grades into the unloading area reserved beside the conveying device, this bamboo strip grade sorting and storage method is not ideal. A larger unloading area needs to be reserved beside the conveying device, resulting in a larger floor space. In addition, since the bamboo strips are extracted by the extraction device at a high speed, there are certain safety hazards when workers collect the bamboo strips in the unloading area. When the bamboo strips are conveyed forward, due to their inertia, they are likely to miss the corresponding extraction device and continue to be conveyed forward, which affects the bamboo strip grade sorting effect. Utility Model Content

[0004] The utility model provides an automatic unloading device for a bamboo strip shape sorting machine, which aims to overcome the technical problems that the existing method of sorting and storing bamboo strips of different grades is not ideal, occupies a large area, and is easy to miss the corresponding extraction device and continue to be transported forward, thus affecting the bamboo strip grade sorting effect.

[0005] In order to achieve the purpose, the technical solution provided by the utility model is as follows:

[0006] The invention relates to an automatic unloading device for a bamboo strip shape sorting machine, comprising left and right brackets located below a feeding frame and spaced apart on the left and right sides, the left and right brackets each comprising a horizontal cross bar for supporting the bamboo strips to be pushed forward, and a plurality of vertical support rods connected to the top of the horizontal cross bar and spaced apart in sequence in the length direction of the horizontal cross bar, the tops of the plurality of vertical support rods being connected to the bottom of the horizontal cross bar, and a bamboo strip storage space being formed between two adjacent vertical support rods, the plurality of bamboo strip storage spaces constituting sorting and storage areas for bamboo strips of different grades; a plurality of unloading openings located above the corresponding bamboo strip storage space are provided on each horizontal cross bar, and each unloading opening is correspondingly provided with a horizontal block which is level with the height of the horizontal cross bar; one end of each horizontal block is movably connected to the front end of the unloading opening, and the other end thereof can be tilted up to block the bamboo strips so that the bamboo strips fall from the unloading opening into the corresponding bamboo strip storage space.

[0007] Furthermore, each horizontal stopper is generally L-shaped and can be movably connected to the front end of the discharge port through a pin shaft; each horizontal stopper is equipped with a cylinder, the base of which is connected to a side wall of the upper end of a vertical support rod, and its piston rod is connected to the bottom of one end of a corresponding horizontal stopper. A horizontal stopper pushes one end thereof through the piston rod of the corresponding cylinder so that the other end thereof can be tilted up and block the bamboo strips.

[0008] Furthermore, a feeding detection device is provided on the left side of the rear end of the feeding rack, and the feeding rack is equipped with a conveyor chain assembly that pushes the bamboo strips detected by the feeding detection device one by one horizontally to the left and right brackets for automatic grade sorting. The conveyor chain assembly includes a conveyor chain installed on the feeding rack and symmetrical to each other on the left and right, and the left and right conveyor chains are symmetrically provided with a plurality of paddles that can push the bamboo strips on the horizontal cross bar forward; one end of each paddle is symmetrically fixed on the chain links of the left and right conveyor chains, and the other end of each paddle forms a free end.

[0009] Furthermore, an auxiliary drag platform is provided at the bottom of the rear end of the feeding rack body for supporting the bamboo strips that have been inspected by the feeding detection device. The table top of the auxiliary drag platform is at the same height as the left and right brackets. The auxiliary drag platform is located at the rear ends of the left and right brackets, and the front end of the auxiliary drag platform is provided with two horizontal extension rods arranged at intervals on the left and right, and the two horizontal extension rods are located between the two horizontal cross bars, and the rear ends of the two horizontal extension rods and the two horizontal cross bars form a bracket connection area.

[0010] Furthermore, there are two feeding detection devices, and the two feeding detection devices are arranged at intervals in front and behind. Each feeding detection device includes a detection device and a traction component that pulls and transports the bamboo strips to the horizontal crossbar after they are detected by the detection device.

[0011] The technical solution provided by the utility model has the following beneficial effects compared with the existing technology: the structural design of the automatic unloading device is ideal, and a design of multiple blocks with tilted ends is adopted. When unloading, it is only necessary to tilt the rear end of a corresponding block and block the bamboo strips so that the bamboo strips fall from the unloading port into the corresponding bamboo strip storage space to complete the unloading operation. Not only is the unloading safer and occupies less space, but the bamboo strips are blocked when tilted, avoiding the problem of the bamboo strips continuing to be transported forward and missing the corresponding unloading port due to inertia, thereby greatly improving the bamboo strip grade sorting effect.

Space 7, the multiple bamboo strip storage spaces constitute a sorting and storage area for bamboo strips of different grades; each horizontal cross bar 21 is provided with multiple discharge openings 20 located above the corresponding bamboo strip storage space, and each discharge opening 20 is correspondingly provided with a horizontal stopper 23 at the same height as the horizontal cross bar 21; one end of each horizontal stopper 23 is movably connected to the front end of the discharge opening 20, and the other end thereof can be tilted and block the bamboo strips 4 so that the bamboo strips 4 fall from the discharge opening 20 into the corresponding bamboo strip storage space 7.

[0018] Refer to the attached Figure 1 、 Figure 3 and Figure 4 Each horizontal block 23 is generally L-shaped and is movably connected to the front end of the discharge port 20 via a pin 24. Each horizontal block 23 is equipped with a cylinder 25. The base of the cylinder 25 is connected to a side wall of the upper end of a vertical support rod 22, and its piston rod 251 is connected to the bottom of the corresponding end of the horizontal block 23. The piston rod 251 of the corresponding cylinder 25 pushes one end of the horizontal block 23 so that the other end can be tilted up and block the bamboo strips 4, while opening the corresponding discharge port 20, allowing the bamboo strips 4 to fall from the discharge port 20 into the corresponding bamboo strip storage space. At the same time, each horizontal block 23 can be pushed by the piston rod 251 of the cylinder 25 so that its other end can be tilted up to block the bamboo strips 4, effectively avoiding the problem of the bamboo strips 4 continuing to be transported forward and missing the corresponding discharge port due to inertia, greatly improving the bamboo strip grade sorting effect.

[0019] Refer to the attached Figure 1 、 Figure 2 and Figure 4 A feeding detection device 5 is provided on the left side of the rear end of the feeding frame 1. The feeding frame 1 is equipped with a conveyor chain assembly that pushes the bamboo strips 4 detected by the feeding detection device 5 one by one horizontally to the left and right brackets 2 and 3 for automatic grade sorting. The conveyor chain assembly includes conveyor chains 11 and 12 installed on the feeding frame 1 and symmetrical to each other on the left and right sides, and the left and right conveyor chains 11 and 12 are symmetrically provided with paddles 13 that can push the bamboo strips 4 on the horizontal cross bar 21 forward; one end of each paddle 13 is symmetrically fixed to the chain links of the left and right conveyor chains 11 and 12, and the other end of each paddle 13 forms a free end.

[0020] In addition, the number of the feeding detection devices 5 can also be one group, three groups or other appropriate numbers.

[0021] Refer to the attached Figure 1 、 Figure 2 and Figure 4 The rear end bottom of the feeding frame 1 is provided with an auxiliary platform 6 for supporting the bamboo strips 4 after being inspected by the feeding inspection device 5.

The detection device 51 is used to pre-detect the parameter information of the bamboo strips before the bamboo strips 4 are transported to the horizontal crossbar 21, and feed the parameter information back to the controller in real time. The controller controls the actions of multiple cylinders 25, so that the piston rod 251 of a corresponding cylinder 25 drives a horizontal block 23 to tilt, opening a corresponding discharge port 20, so that the bamboo strips 4 fall from the discharge port 20 into the corresponding bamboo strip storage space, thereby completing the sorting and storage of bamboo strips of different grades. Each horizontal block 23 can be pushed by the piston rod 251 of the cylinder 25 so that its other end can be tilted to block the bamboo strips 4. The traction assembly 52 comprises a traction frame and two conveyor wheel assemblies spaced apart from each other. The detection device 51 is mounted on one traction frame and located between the two conveyor wheel assemblies. Each conveyor wheel assembly includes a driving wheel and a driven wheel corresponding to upper and lower portions, forming a traction channel for the bamboo strips to pass through. During operation, the bamboo strips 4 sequentially pass through the left conveyor wheel assembly, the detection device 51, and the right conveyor wheel assembly. As the bamboo strips 4 pass through the detection device 51, parameter information related to the bamboo strips is collected. The detection method of the feeding detection device 5 is based on existing technology (i.e., a bamboo strip shape detection device). The applicant previously applied for a patent titled "A Bamboo Strip Shape Detection Device" (Note: Patent No.: ZL 202120404498.3, Authorization Publication Date: 2021-10-22), which detailed the specific structure of the detection device 2 and traction assembly 52, as well as the principles of the detection technology, and will not be repeated here.
