Detailed description of the invention
Below, with reference to accompanying drawing, the utility model is elaborated.
As shown in Figure 1 and Figure 2, chassis feedway 1 of the present utility model has: framework 2; Be arranged at travelling with track 3 on framework 2; Load in travelling with the chassis 4 on track 3.Framework 2 is level, and chassis 4 moves back and forth with track 3 via travelling on this framework 2.
Be provided with the motor 5 with S. A. 6 in one end of framework 2 (being left end in the present embodiment), be provided with the S. A. 7 that is supported on bearing 8 at the other end of framework 2.Be separately installed with sprocket wheel 6a, 7a at S. A. 6 and S. A. 7.
The roller chain 9 with end is wound around between S. A. 6,7 sprocket wheel 6a, 7a separately.Be combined with front side, the rear side of the direct of travel of chassis 4 respectively in the both ends of roller chain 9.In addition, in the present embodiment, the left side of Fig. 1 and Fig. 2 is front side, and right side is rear side.In addition, so-called roller chain 9 refers to chassis 4 " combination ", except the situation of roller chain 9 and chassis 4 direct combinations, also comprise roller chain 9 via miscellaneous parts such as bonded blocks with the situation of chassis 4 combinations.
As shown in FIG. 2 and 3, below roller chain 9 to be provided with supporting track 10 along the mode of roller chain 9.Supporting track 10 is with the roller chain 9 that supports respectively the mode of roller chain 9 of upside and downside and be arranged at above-mentioned upside, downside below separately.
The spring 11 of coiled type is installed at the rear side of chassis 4.One end of spring 11 is connected with chassis 4, and stretches in the direction identical with the direct of travel of chassis 4.The rear side of this external chassis 4 is provided with support 12, can be arranged at slidably support 12 as the pin 13 of bonded block.And the other end of spring 11 is connected with pin 13, is connected with the end of roller chain 9 on pin 13.
On the other hand, be provided with the support 14 as bonded block in the front side of chassis 4, on support 14, be directly connected with the end of roller chain 9.But the front side of chassis 4 also can identically with rear side become the structure that adopts spring.
In present embodiment, be provided with the semicircular feature 15,15 with semi-circular shape at front side, the rear side of chassis 4.Each end of roller chain 9 is with the mode bending of the semi-circular shape along semicircular feature 15,15, and is connected with support 14 or pin 13.In addition, semicircular feature 15 also can only be installed on the either side of the front and back of chassis 4.Herein, " end " of so-called roller chain 9 refers to following part: comprise with " end " of chassis 4 combinations and near " part " that should " end " for example, with the part of the mode bending along semicircular feature 15.
Next the action of chassis feedway 1 is described.
First, as shown in Figure 1, 2, chassis 4 is disposed to carry and starts place.In the present embodiment, be Fig. 1,2 right side.Under this state, transported material 16 loads on chassis 4.In addition, in present embodiment, transported material 16 is mold board chassis, and transported material 16 is carried towards chassis 4 from the direction of the arrow A shown in Fig. 1 and Fig. 3.
Next CD-ROM drive motor 5 pulls roller chain 9, and to the direction conveying carrier 4 of arrow B.Now, the roller chain 9 of upside is pulled by the driving of motor 5, therefore can not produce lax.On the other hand, although that the roller chain 9 of downside produces is lax, this is lax is supported track 10 and supports, thereby roller chain 9 can not become sagging state.And now, by the elongation of spring 11, and pull roller chain 9 via pin 13.That is, the lax of roller chain 9 absorbed by the elongation of spring 11, therefore can eliminate roller chain 9 lax of downside.
Roller chain 9 is pulled by the driving of motor 5, and the end of roller chain 9 is also pulled with the connecting portion of the support 14 that is installed on chassis 4 thus.But roller chain 9 is connected with support 14 with the mode bending along semicircular feature 15.Therefore,, if pull roller chain 9 by the driving of motor 5, roller chain 9 is pushed hard and is pressed on semicircular feature 15.That is, pull the major part of the power of roller chain 9 to be passed to semicircular feature 15, thereby put on the connecting portion of support 14 and roller chain 9, chassis 4 significantly reduces with the power of the joint portion of roller chain 9.Therefore, can significantly extend the life-span of this connecting portion or joint portion.
Chassis 4 arrives to be carried after terminal (left side of Fig. 2), carries transported material 16 from chassis 4.Transported material 16 is carried towards the direction of the arrow C shown in Fig. 1,3.
Transported material 16, after chassis 4 is handled upside down, makes motor 5 contrarotations and to the opposite sense conveying carrier 4 of arrow B.Now, the roller chain 9 of downside is pulled.The roller chain 9 of upside produces lax, but is supported as hereinbefore that track 10 supports thereby can be not sagging.
In addition, although the connecting portion of the end of roller chain 9 and pin 13 is also pulled, roller chain 9 is connected with pin 13 with the mode bending along semicircular feature 15.Therefore, if pull roller chain 9 by the driving of motor 5, roller chain 9 is pushed hard and is pressed on semicircular feature 15, thereby the power that puts on the connecting portion of pin 13 and roller chain 9 significantly reduces.Therefore, spring 11 is hardly because pulling the power of roller chain 9 compressed, can not exert an influence to the action of chassis because of the compression of spring 11 and elongation afterwards thus.
