Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.Following examples only for technical scheme of the present invention is clearly described, and can not limit the scope of the invention with this.
As shown in Figure 2, a kind of method for designing of books sorter, comprises the following steps:
Step one, analyzes existing books sorter, finds out technical contradiction.
The project organization too complex of existing books sorter, manufacturing cost and difficulty higher, floor space is large, so new design wishes that the characteristic that can improve is the complexity of reduction system, while reducing system complexity at that time, inherently make the structure of books sorter produce to change, reduce the efficiency of books sorter; Therefore the technical contradiction of books sorter is the conflict between structural complexity and sorting efficiency now.
Step 2, selects a pair characteristic parameter representing technical contradiction from 39 general engineering parameter lists; Described characteristic parameter is No.36 and No.25.
Step 3, brings characteristic parameter No.36 and No.25 obtained in step 2 into collison matrix, determines inventive principle.
Collison matrix is prior art, specifically as shown in Table 1
Table one 39 × 39 contradiction matrix abridged table
In conjunction with collison matrix, confirmable inventive principle is that No.6 versatility principle and No.29 are pneumatic with hydraulic structure principle.
Step 4, according to inventive principle design solution.
Analyze No.6 versatility principle, No.6 versatility principle enables an object complete multiple function, can reduce the quantity completing object needed for these functions in former design.Because the multiple conveying mechanisms 4 in the sorting equipment of existing sorter are identical and separate work, therefore can replace with a conveying mechanism 4, and this conveying mechanism 4 is arranged on sorting small rail car 3 realizing diverse location.In sum, solution according to No.6 versatility principle design is: replaced by the conveying mechanism 4 of the multiple conveying mechanisms 4 in the sorting equipment of existing books sorter, and is arranged on by this conveying mechanism 4 and small rail car 3 realizes the sorting of books basic class.
Analyze with hydraulic structure principle No.29 is pneumatic, No.29 is pneumatic is the solid parts of object pneumatic or hydraulic unit are replaced with hydraulic structure principle, gas or liquid is used for expanding or vibration damping.Because books are generally divided into 22 basic class by existing sorter, concrete segmentation still passes through manual sorting, when run into that vacation, the new term begins or the peak period of student's also book time, workload is very big, both proposes challenge to the staff in library, and causes again books to stack, hinder the circulation of books, therefore can design a hoistable platform 2, small rail car 3 is arranged on hoistable platform 2, be realized the sorting more specifically of books by the motion of small rail car 3 and hoistable platform 2.In sum, pneumaticly according to No.29 with the solution of hydraulic structure principle design be: design hoistable platform 2 in order to realize books large class under the sorting of group.
According to the books sorter of above-mentioned method for designing design, as shown in Figure 3, comprise recognition device, book management system, the conveyer 1 that be successively set on recognition device downstream and the sorting equipment supporting with recognition device, recognition device, conveyer 1 and sorting equipment are controlled by PLC entirety.
As shown in Figure 4, sorting equipment comprises sorting platform and bookshelf 5, sorting platform comprises support 8, hoistable platform 2 and small rail car 3, hoistable platform 2 is fixed on support 8, this hoistable platform 2 is electric up-down rod structure, some self locking lifting rods 7 are also provided with between the work top of hoistable platform 2 and support 8, the work top of hoistable platform 2 is provided with the track mated with small rail car 3, here work top shape is rectangle, track is arranged along the length direction of work top, small rail car 3 can move in orbit, small rail car 3 is provided with conveying mechanism 4, the drive motors driving conveying mechanism 4 to work and the drive motors of drive track dolly 3 movement, this conveying mechanism 4 is roller conveyor structure, its throughput direction is along the width of work top, bookshelf 5 is placed on the side and the downstream being positioned at conveying mechanism 4 of sorting platform.
As shown in Figure 5, above-mentioned self locking lifting rod 7 comprises at least two sheathed successively from inside to outside lifting poles and retaining mechanism.As shown in Figures 6 and 7, retaining mechanism comprises spring 74, the two ends of spring 74 are all fixed with multidiameter 73, the little axle of multidiameter 73 outwardly, the length of little axle is greater than the wall thickness of lifting pole, adjacent lifting pole is respectively interior pole 72 and outer pole 71, relative both sides, interior pole 72 bottom are provided with the through hole mated with the little axle of multidiameter 73, relative both sides, outer pole 71 top are provided with the through hole mated with the little axle of multidiameter 73, the little axle being positioned at the multidiameter 73 at spring 74 two ends is embedded in the through hole of pole 72 both sides respectively, and spring 74 is in compressive state.When interior pole 72 rises to the top of outer pole 71, the little axle of multidiameter 73 pushes the through hole of outer pole 71 under the effect of spring 74, realizes self-locking.
In order to improve sorting efficiency further, the sorting equipment of described books sorter has two, and arranged side by side is arranged on conveyer 1 downstream, in order to coordinate with two sorting equipments, be configured with two bookshelves 5, the downstream of each conveying mechanism 4 is all placed with a bookshelf 5, each bookshelf 5 is arranged nine layer of 11 row book frame, i.e. every platform sorter, sort 11 large classes, be divided into nine groups in each large class, move for the ease of bookshelf 5, bottom bookshelf 5, be also provided with universal wheel 6
The course of work of above-mentioned books sorter: when books are given back by reader, books are first through recognition device identification, controlled 22 kinds of basic class books to be divided into A--K and N--Z two parts by PLC, A--K 11 kinds of books are transported on the conveying mechanism 4 of a sorting equipment through conveyer 1, N--Z 11 kinds of books are transported on the conveying mechanism 4 of another sorting equipment through conveyer 1, the small rail car 3 of sorting equipment moves on bookshelf 50 one row diverse location respectively under the control of PLC, then the hoistable platform 2 of sorting equipment moves on bookshelf 5 nine layers of diverse location respectively under the control of PLC, when moving to the position with books type matching, books are sent into book frame by the conveying mechanism 4 that PLC controls sorting equipment.
In sum, method for designing of the present invention have employed TRIZ theory, by collison matrix determination inventive principle, according to inventive principle design solution, the books sorter designed by the method is effectively overcome existing books sorter complex structure, takes up an area greatly, invests the shortcomings such as large.The books sorter adopting above-mentioned method for designing to design improves on existing books sorter, multiple conveying mechanisms 4 during sorting equipment is multiple conveying mechanism 4 replaces, conveying mechanism 4 is arranged on small rail car 3, small rail car 3 is arranged on hoistable platform 2, by the motion of small rail car 3 and hoistable platform 2, realize the sorting of books, volume be little, cost is low, sorting efficiency high.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the technology of the present invention principle; can also make some improvement and distortion, these improve and distortion also should be considered as protection scope of the present invention.
