Description
Technical Field
[0001] The utility model belongs to the technical field of unburned brick production equipment, and in particular relates to a device for grabbing and stacking unburned bricks. Background Art
[0002] After the unburned bricks are pressed and formed and the curing cycle is completed, they need to be transferred from the curing site to the packaging line for packaging. Usually, the unburned bricks are packed in the following ways: stacking and placing them layer by layer on the pallet and placing the adjacent layers of unburned bricks vertically to improve the stability of the brick stack. A layer of protective film is set between the adjacent layers of unburned bricks as an interlayer to avoid damage to the unburned bricks due to mutual squeezing and friction during transportation. Therefore, the packaging process of unburned bricks is usually the stacking process of unburned bricks.
[0003] As mentioned above, in order to enhance the compactness of the brick stack and prevent the brick stack from becoming loose and collapsing during movement, adjacent layers of unburned bricks are placed in an alternating manner, which requires that when the unburned brick stack is formed, the next layer of unburned bricks needs to be rotated 90° during stacking. Therefore, the process of forming an unburned brick stack is not a simple process of stacking unburned bricks, but a composite operation involving shifting, lifting, and the aforementioned rotation. Currently, due to the lack of suitable stacking devices, the stacking of unburned bricks requires more manual participation, which reduces the production efficiency of the brick production line. Utility Model Content

[0021] In order to further understand the content, features and effects of the present invention, the following embodiments are given to explain in detail.
[0022] See also Figure 1 and Figure 2 The utility model of the unfired brick grabbing and stacking device comprises a translation frame 9, a guide assembly and a lifting bracket 8 which is lifted and moved along the vertical direction defined by the guide assembly are installed in the middle of the translation frame 9, a rotary drive assembly is installed at the lower end of the lifting bracket 8, and a grabbing assembly is installed below the rotary drive assembly.
[0023] Under the driving action of the external translation drive assembly, the translation frame 9 moves in translation, so that the rotary drive assembly and the grabbing assembly below can be translated and displaced. Under the driving action of the external lifting drive assembly, the lifting bracket 8 moves in lifting and lowering, so that the rotary drive assembly and the grabbing assembly below can be lifted and displaced. The rotary drive assembly drives the grabbing assembly to rotate a certain angle (usually 90°), so that the grabbing assembly can rotate at a certain angle. Therefore, the unfired bricks grabbed by the grabbing assembly can be translated, lifted, displaced, and rotated. The grasping and stacking are realized by translation and lifting, and the staggered stacking of adjacent unfired brick layers is realized by rotation.
[0024] In this embodiment, the translation frame 9 includes two side beams that are arranged opposite to each other, a plurality of connecting beams are provided between the two side beams, and travel wheels 10 are installed below the ends of the two side beams.
[0025] The travel drive assembly may include a travel drive motor mounted on the translation frame 9, and a travel gear is mounted on the output shaft of the travel drive motor. The present grabbing and stacking device needs to be mounted on a frame, and a travel rack is mounted on the top of the frame. The travel gear falls on the travel rack, and the travel drive motor drives the travel gear to roll along the travel rack to achieve a translation drive effect. In order to improve the stability of the translation movement, a track is set on the frame, and a track block is set on the translation frame 9 and the track block is located on the track.
[0026] In this embodiment, the guide assembly includes two sets of guide bases 11 fixedly mounted in the middle of the translation frame 9, guide wheels 12 are mounted on the guide bases 11, and guide rails are mounted on both sides of the lifting bracket 8 and are located in the track grooves on the rims of the guide wheels 12. Figure 1 As shown in the figure, the guide rail is an angle steel welded and installed on the side of the lifting bracket 8. Accordingly, a track groove with a triangular cross-section is provided on the rim of the guide wheel 12. When the lifting bracket 8 is lifted and moved, the stability of the lifting bracket 8 and its accessories in the lifting and moving is guaranteed due to the limiting effect of the guide base 11 and the guide wheel 12.
[0027] The lifting drive assembly can be a lifting cylinder, or a sprocket is installed at the bottom of the lifting bracket 8, and sprockets are installed on two sets of guide bases 11, so that the middle part of a chain bypasses the sprocket on the lifting bracket 8, and both ends extend upward and bypass the sprockets on the two sets of guide bases 11. One end of the chain is fixed, and the other end is driven by a lifting drive motor. In this way, when the lifting drive motor drives the chain to move outward, the lifting bracket 8 can move upward, and conversely, when the lifting drive motor drives the chain to move inward, the lifting bracket 8 can move downward.
[0028] See also Figure 2 , Figure 3 and Figure 4 , we can see that:
[0029] The grab assembly includes a central base 4, on which two groups of supporting beams 14 are mounted, and below the ends of the two groups of supporting beams 14 are mounted jaws 2 and grab cylinders 16 for driving the jaws 2 to move inward and outward. A pressure bar 1 is also mounted between the jaws 2, and a holding cylinder 13 for driving the pressure bar 1 to move up and down is also mounted at the bottom of the central base 4.
[0030] The four grabbing cylinders 16 drive the four clamping claws 2 to move synchronously. When the clamping claws 2 move inward synchronously, the unburned bricks inside are clamped. When the clamping claws 2 move outward synchronously, the unburned bricks inside are released. The function of setting the pressing bar 1 driven by the pressing cylinder 13 to move up and down is: before grabbing and clamping, the pressing bar 1 is used to press and fix the unburned bricks below, so that when the clamping action occurs and during the displacement process of the unburned bricks after being grabbed, the unburned bricks will not shake, and the stability is better.
[0031] In this embodiment, guide rails 15 are installed below the ends of the two groups of supporting beams 14, and the top of each clamping jaw 2 is fixedly connected to the guide slider on the upper guide rail 15. In this way, the stability of each clamping jaw 2 moving inward or outward is improved through the limiting and guiding function provided by the guide rail 15.
[0032] In this embodiment, an inner base 19 is installed at the bottom of the middle base 4, a flexibly rotatable stabilizing gear 18 is installed on the inner base 19, and a stabilizing rack 17 is fixedly installed on each clamping jaw 2, and the stabilizing rack 17 is meshed and driven with the corresponding stabilizing gear 18. In this way, when the clamping jaw 2 moves inward and outward, the stabilizing rack 17 moves inward and outward synchronously, and the stabilizing rack 17 drives the stabilizing gear 18 to rotate, which further improves the stability of each clamping jaw 2 when it moves inward or outward.
[0033] In this embodiment, protective covers 3 are installed around the central base 4, and each protective cover 3 is buckled above the end of two groups of supporting beams 14. The tops of the four clamping jaws 2 and the guide rails 15 are respectively located inside the four protective covers 3. In this way, the protective covers 3 provide a certain protection function, which can prevent foreign objects from entering the internal space to cause jamming problems to a certain extent, and also improve the safety of operation to a certain extent.
[0034] See also Figure 2 , we can see that:
[0035] The slewing drive assembly includes a slewing main gear 5 mounted and fixed on the middle base 4, and a bearing seat 6 mounted and fixed on the lower end of the lifting bracket 8. The outer ring of the bearing in the bearing seat 6 is fixedly connected to the middle base 4. A slewing drive motor 7 is also installed on the side of the bearing seat 6. A driving gear is installed on its output shaft and the driving gear is meshed with the slewing main gear 5 for transmission. When it is necessary to drive the grabbing assembly below to rotate, the slewing drive motor 7 is turned on, and the slewing main gear 5 is driven to rotate through the driving gear, and the grabbing assembly rotates accordingly.
[0036] How to run:
[0037] The end of the conveyor line for unfired bricks extends to the bottom of the frame where the grabbing, stacking and palletizing device is located. When the unfired bricks are transferred to the end of the conveyor line, the translation frame 9 drives the grabbing assembly to move above the unfired bricks, and then the lifting bracket 8 drives the grabbing assembly to descend, so that the unfired bricks are located in the space between the clamps 2, and the pressure bar 1 descends and is pressed and fixed on the unfired bricks, and then the clamps 2 move inward synchronously to clamp the unfired bricks; then the lifting bracket 8 rises and the translation frame 9 translates and shifts to move the unfired bricks above the terminal position (usually on the pallet at the head end of the packaging line), and rotates 90° or not as needed, and then the lifting bracket 8 descends, and the clamps 2 move outward to release the unfired bricks onto the pallet, completing the grabbing, stacking and palletizing of a layer of unfired bricks; repeat the above-mentioned action process, grab and stack the unfired bricks layer by layer, and the adjacent layers of unfired bricks should be staggered to improve the density.
