Detailed Description
The present invention will be described in further detail with reference to examples, wherein the directions indicated in the drawings are referred to hereinafter as the X-direction and the Y-direction.
Example 1:
the embodiment of the invention provides a stacker with a buffer area, as shown in fig. 1, which comprises a stacker seat 700, a stacker frame 800, a translation mechanism, a cargo carrying table lifting mechanism 703, a cargo carrying table and a buffer area 600. The stacker seat 700 in this embodiment is of a plate type structure, and the translation mechanism is mounted on the stacker seat 700 and includes a bottom traveling wheel 701, a top traveling wheel 702, and a reduction motor for driving the bottom traveling wheel 701 to operate. As shown in fig. 1, since the stacker of this embodiment is additionally provided with the buffer area 600, it is heavier than the conventional stacker, and a total of four upper and lower tracks, that is, the double ground tracks 501 and the double sky tracks 502 in fig. 1, need to be arranged in the warehouse to improve the walking stability of the stacker. The double ground rails 501 in fig. 1 are raised by angle steel, the stacker car seat 700 is not arranged on the bottom walking wheels 701, but the bottom walking wheels 701 are arranged on two sides of the stacker car seat 700, so that the stacker car seat 700 can sink.
The cargo bed lifting mechanism 703 is used for driving the cargo bed to move up and down along the stacker frame 800, as shown in fig. 1, the cargo bed lifting mechanism 703 is installed at the front end of the stacker seat 700, and drives the steel cable to pull through the motor, and the cargo bed is connected with the stacker frame 800 in a sliding manner, so that the cargo bed slides up and down along the stacker frame 800. As shown in FIG. 1, the stacker frame 800 of this embodiment has four upright structures, and two more upright structures than the conventional stacker, so that the lifting of the cargo carrying platform on the frame has four rails, and the problem that the conventional stacker needs to increase rigidity due to the cantilever is solved. The sliding connection between the cargo carrying platform and the stacker frame 800 in this embodiment is realized by connecting slideways to four vertical columns of the stacker frame 800, arranging a three-sided encircling guide wheel 801 capable of sliding on the slideways on one side of the cargo carrying platform, and arranging a single-sided supporting guide wheel 802 capable of sliding on the slideways on the other side of the cargo carrying platform, so as to prevent the lifting process from being locked, as shown in fig. 12 and 13.
The buffer area 600 of this embodiment has a total of 8 layers, as shown in fig. 2, 8 layers from the buffer area a601 to the buffer area H608 are distributed along the Z direction, each layer is provided with a buffer conveyor 612 capable of operating independently and driven bidirectionally, the buffer conveyor 612 is distributed along the X direction, and both ends of the conveying direction are provided with retractable blocking blocks 613. Each layer of the buffer conveyor belt 612 is divided into three storage positions, each storage position is provided with a detection sensor 614, and as shown in fig. 3, the buffer area H608 is divided into three cargo positions, namely a buffer area H1609, a buffer area H2610 and a buffer area H3611. As shown in fig. 1, since the buffer area 608 of this embodiment is opened at both ends of the buffer conveyor 612, feeding at one end and discharging at the other end can be realized by the buffer conveyor 612. When only goods are loaded, the telescopic blocking block 613 at the loading end contracts to give way, and the telescopic blocking block 613 at the unloading end extends out to stop; when only goods are discharged, the telescopic blocking block 613 at the discharging end contracts and moves to the abduction position, and the telescopic blocking block 613 at the feeding end extends out to stop; when one end is used for feeding and the other end is used for discharging, the telescopic blocking blocks 613 at the two ends are simultaneously contracted and abducted; when the loading and unloading process is not performed, the retractable blocking block 613 extends to perform both-end blocking. The detecting sensor 614 is used for confirming whether goods are conveyed in place, and the accuracy of each loading and unloading is ensured. Since both ends of the buffer area 608 can enter and exit the goods, compared with the conventional stacker, when the goods are put in storage, the goods do not need to enter from the goods carrying platform in a package manner, and the goods are directly put into the buffer area 608 from one end far away from the goods carrying platform in a butt joint manner (the goods outside the warehouse are put into the buffer area, the goods can be put into the buffer area by adopting a lifting platform with a conveyor belt device, a new lifting storage device can be designed according to the structure of the buffer area, which is not the invention point of the present invention, so that excessive description is not needed), and the working efficiency is improved.
