Detailed Description
The bread box turnover device shown in the attached figure 1 comprises a turnover mechanism, a conveying mechanism and a clamping mechanism; the bread box 32 is conveyed to the turnover mechanism from the bread production line and is further brought into the turnover mechanism through the conveying mechanism, then the clamping mechanism rotates to clamp the bread box 32 tightly, the turnover mechanism is started at last, the bread box 32 is turned over together with the conveying mechanism and the clamping mechanism, the bread stops for several seconds, the bread automatically falls out of the bread box 32, the turnover mechanism resets, then the clamping mechanism releases the bread box 32, the whole process is completed, the process is simple and clear, and the production efficiency is greatly improved.
The following is to further describe the structure of the present invention, as shown in fig. 2 and fig. 3, the turnover mechanism includes a rotation axis driving motor 30 and a rotation axis 26 connected to the rotation axis driving motor 30, fixing bases 29 for fixing the rotation axis 26 are installed at two ends of the rotation axis 26, and a fixing plate 25 is installed at one side of the fixing base 29. The cross sections of both ends of the rotating shaft 26 are cylindrical, the cross section of the middle section is square, and the fixing plate 25 is installed at one section of the square cross section, so that the fixing plate 25 can rotate along with the rotating shaft 26 without using connecting and fixing members such as pins.
A first sensor 28 for sensing the turning angle of the fixing plate 25 is arranged at one side of the fixing plate 25, then two positioning screws 27 are respectively arranged at two ends of the fixing plate 25, and when the turning mechanism is in an original state, the first positioning screws 27 are positioned at the first sensor 28; the rotating shaft driving motor 30 is started, the rotating shaft 26 drives the conveying mechanism and the clamping mechanism to rotate, when the turnover mechanism is turned over by one hundred eighty degrees, the second positioning screw 27 is located at the first sensor 28, the first sensor 28 gives an indication to the system, the fact that the turnover mechanism is turned over by one hundred eighty degrees is indicated, the system gives an instruction, the turnover mechanism stops turning over, and the turnover mechanism is reset after being stopped for a period of time.
The conveying mechanism is arranged on one side of the rotating shaft 26 and rotates along with the rotating shaft 26, and comprises a transmission shaft driving motor 5, a transmission shaft 4 and a conveying chain 1 which is connected with the transmission shaft 4 and used for conveying the bread box 32, wherein a driving chain 3 is arranged on the transmission shaft driving motor 5 and connected with the transmission shaft 4, and two ends of the transmission shaft 4 are arranged on the fixing plate 25. The conveying chains 1 are respectively provided with one conveying chain 1 on two sides of the turnover mechanism, the driving chain 3 drives one of the transmission shafts 4 to rotate, the transmission shafts 4 drive the conveying chains 1 on two sides to move, and the conveying chains 1 drive the other transmission shaft 4 to rotate. The utility model discloses still set up a bearing 10 that is used for supporting drive chain 3 on drive chain 3, then install on the member through a bearing frame 9, as shown in figure 4.
The second sensor 7 for sensing the position of the bread box 32 is arranged on one side of the transmission chain 1, when the second sensor 7 senses the bread box 32, the system is immediately sent out an instruction, then the system sends out an instruction to stop the transmission shaft driving motor 5, the transmission chain 1 stops conveying, the bread box 32 reaches a designated position, and then the next clamping process is carried out.
The clamping mechanism is arranged in the middle of the rotating shaft 26 and rotates along with the rotating shaft 26, and comprises a shaft sleeve driving cylinder 16 and a shaft sleeve 21 which is connected with the shaft sleeve driving cylinder 16 and sleeved on a shaft rod, wherein a buckle 23 for rotatably clamping the bread box 32 is arranged on the shaft sleeve 21.
In order to simplify the installation, reduce the volume, the utility model discloses install axle sleeve 21 on transmission shaft 4, axle sleeve 21 both ends are equipped with bearing 14, just so even transmission shaft 4 rotates, also can not drive axle sleeve 21 and rotate.
Preferably, the shaft sleeve 21 is provided with a gear 31, the shaft sleeve driving cylinder 16 is provided with a rack 17 connected to the gear 31, and the rack connection can provide more stable and larger clamping force relative to the chain. A support bar 24 is provided below the rack 17 to prevent the rack 17 from being bent after being extended without being effectively engaged with the gear 31, which is an accident.
