DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0028] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] Example 1

[0030] Reference Figure 1-7 This embodiment provides a palletizing device, including a vibrating loosener 1, a screening conveyor 2, a rocker conveyor 3, a flat conveyor 4 and a stacker 5 which are arranged in sequence; the vibrating loosener 1, the screening conveyor 2, the rocker conveyor 3, the flat conveyor 4 and the stacker 5 are fixedly arranged on a frame 7 in sequence.

[0031] The vibration loosening machine 1 includes a vibration plate 11 which is arranged obliquely and a vibration mechanism 12 for controlling the vibration of the vibration plate 11; one corner of the material inlet side of the vibration plate 11 is higher than the diagonal corner, and the other diagonal corners of the vibration plate are on the same horizontal line. A fixed baffle 13 is arranged on the relatively low side of the vibration plate 11, and the fixed baffle 13 is parallel to the material transportation direction and is located on the low diagonal side. After the material is placed in the vibration loosening machine 1, it is loosened under the action of the vibration mechanism 12, and the vibration plate 11 is arranged obliquely, so the material can move toward the screening conveyor 2 under the dual action of gravity and vibration. At the same time, because one side of the vibration plate 11 is lower than the other side, one end of the material will be aligned under the action of the fixed baffle 13.

[0032] The outlet of the vibrating loosener 1 is located above the screening conveyor 2, which includes two first synchronous belts 21 parallel to the material transport direction, and the distance between the two first synchronous belts 21 is less than the length of the standard material. When the material moves to the screening conveyor 2, if the length of the material is less than the distance between the two first synchronous belts 21, it will fall between the two first synchronous belts 21, and the material shorter than the standard length will be screened out.

[0033] The rocker conveyor 3 includes two groups of symmetrically arranged rocker assemblies 31, which include a fixed plate 311 with a serrated groove, a rocker tray 312 with the same groove as the fixed plate 311, and a rocker 313 connecting the fixed plate 311 and the rocker tray 312. One end of the rocker 313 is connected to the fixed plate 311 through a bearing, and the other end of the rocker 313 is fixedly connected to the rocker tray 312. The rocker tray 312 is driven to rotate by controlling the rocker 313 to rotate. The materials in the grooves of the fixed plate 311 and the rocker tray 312 are moved up and down by the rotation of the rocker tray 312, thereby achieving the purpose of transporting a single piece of material.

The qualified length of the material moves along the first connecting plate 3111 to the serrated groove above the fixed plate 311 and the rocker tray 312, and is transported downward by the rocker mechanism to achieve the purpose of conveying a single piece of material. During the transportation process, the staff can determine whether the material is qualified based on experience, and then take away the unqualified material; or set the second connecting plate 3112 as a retractable structure, control its extension and contraction through the hydraulic cylinder, so that the unqualified material falls below the second connecting plate 3112, so as to achieve the purpose of removing unqualified products. Complete the secondary screening work.

[0034] The flat conveyor 4 includes two second synchronous belts 41 parallel to the material transport direction, and the two second connecting plates are in contact with the upper ends of the two second synchronous belts 41 of the flat conveyor 4. The material after the secondary screening is transported by the flat conveyor 4.

[0035] The stacking machine 5 includes a workbench 51, a first transmission assembly 52 for controlling the up and down movement of the workbench 51, a tooling frame 53 arranged above the workbench 51 and slidably connected to the workbench 51, a second transmission assembly 54 for controlling the sliding of the tooling frame 53, and a telescopic extrusion plate 55 fixedly arranged on the workbench 51; the first transmission assembly 52 includes four first hydraulic cylinders 521, the cylinder bodies of the first hydraulic cylinders 521 are fixedly arranged on the frame 7, and the piston rods of the first hydraulic cylinders 521 are fixedly arranged on the workbench 51.

The fourth hydraulic cylinder is fixedly arranged on the end surface of the workbench 51. A through hole for accommodating the movement of the piston rod of the fourth hydraulic cylinder is opened on the workbench 51, and the piston rod of the fourth hydraulic cylinder is fixedly connected to the telescopic extrusion plate 55.

[0036] A groove 511 is provided on the workbench 51 , and a ridge 5311 matching the groove 511 is provided on the bottom plate 531 . The second transmission assembly 54 includes a second hydraulic cylinder 541 , the cylinder body of the second hydraulic cylinder 541 is fixedly provided on the workbench 51 , and the piston cylinder of the second hydraulic cylinder 541 is fixedly connected to the bottom plate 531 .

[0037] The tooling frame 53 includes a bottom plate 531, a baffle 532 fixedly arranged on a single side of the bottom plate 531, a column 533 fixedly connected to the bottom plate 531, and a liftable top plate 534; the column 533 is arranged at one end away from the flat conveyor 4; the top plate 534 is controlled to move up and down by the third transmission assembly 56; the bottom plate 531, the column 533 and the top plate 534 are provided with a binding rope groove 535.

[0039] Under the action of gravity and inertia, the material moves to the position of the bottom plate 531 close to the column 533, and then the second hydraulic cylinder 541 is controlled to move the bottom plate 531 away from the flat conveyor 4. According to this method, the entire bottom plate 531 is covered, and then the fourth hydraulic cylinder is controlled to extend the telescopic extrusion plate 55 by a material thickness. While the third hydraulic cylinder 561 is controlled to squeeze the material stack through the top plate 534, the second hydraulic cylinder 541 is used to push the bottom plate 531 toward the flat conveyor 4 until the first row of material layers is tightly fitted; then the third hydraulic cylinder 561 is controlled to raise the top plate 534 to the level of the flat conveyor 4, and the first hydraulic cylinder 521 is controlled to move the workbench 51 downward as a whole by a material thickness, and then the second hydraulic cylinder 541 is controlled to move the column 533 and the end face of the flat conveyor 4 output port 2 material widths away, and then the above steps are repeated to stack the materials layer by layer.

The material stack after extrusion is bundled by the bundle rope pre-set in the bundle rope groove 535. Then, the uneven end of the material stack is cut and then transported out. The bundler 6 is a commercial product, and its structure is prior art, which will not be described in detail.
