Fig. 2 is that expression is as an embodiment of conveyer of the present invention, the figure of the cross sectional shape that the curve part of ladder orbit has.Conveyer 1 of the present invention is embodied in conveyer ladder orbit 5C.The short brink that the conveyer that Fig. 2 represents has a L font with ladder orbit 5C becomes the structure of hollow.(a) is illustrated in conveyer with among the ladder orbit 5C, the figure of the example of the cross sectional shape under the situation of a part of opening of the end of the minor face in the hollow space in Fig. 2.(b) is illustrated in the hollow space in Fig. 2, with the figure of the example of cross sectional shape under the situation of a part of opening on parallel limit, the limit of (a) split shed.And (c) be in the expression hollow space, with in vertical limit, the limit of (a) and (b) split shed, the figure of the example of the cross sectional shape under the situation of a part of opening of the short brink of L font.In each example that Fig. 2 represents, opening is represented as peristome 17.
The conveyer of conveyer of the present invention is represented as block diagram in Fig. 3 with the example of the state of ladder orbit 5C bending.Fig. 3 is illustrated under conveyer has Fig. 2 with the cross sectional shape of ladder orbit 5C the situation of cross sectional shape of (c) expression, the state of four kinds of bendings of enforcement.Be that the roller 6 of ladder 4 usefulness is under the situation of shape of (c) expression of Fig. 2 at cross sectional shape: when cross-section, become the face of straight line 15 or when cross-section, become any structure that the limit is moved in the face of straight line 16.Therefore by bending direction being changed into the either direction in the four direction and being formed, remove journey siding track 51 and backhaul siding track 52 these both directions thereby can tackle with identical cross sectional shape.The conveyer that (a) illustrates in Fig. 3 is to making peristome 17 become the example of the direction bending of curved interior with ladder orbit 5C, (b) conveyer that illustrates is to making peristome 17 become the example of the direction bending of curved outside with ladder orbit 5C, (c) conveyer that illustrates is to making long side become the example of the direction bending of curved outside with ladder orbit 5C, and the conveyer that (d) illustrates is to making long side become the example of the direction bending of curved interior with ladder orbit 5C.
Fig. 4 is at conveyer of the present invention, its ladder orbit is shown to the figure of the example of framework installation.(a) observes the block diagram that ladder orbit 5C is installed on the example of framework 21 from the direction vertical with respect to the length direction of ladder orbit in Fig. 4.Ladder orbit 5C arranges drive track 5A and the servo-actuated track 5B of journey siding track 51 respectively in the both sides of framework 21, and the drive track 5A of backhaul siding track 52 and servo-actuated track 5B amount to four.Fig. 4 (a) represents its installation example.As install towards, as an example of expression among Fig. 4 (a), in four ladder orbit 5C, several be mounted at long side move, remaining several situations about being mounted in the short brink operation it is also conceivable that in addition situation or four ladder orbit 5C that four ladder orbit 5C all are mounted in the long side operation all are mounted to situation about moving at short brink.It is also conceivable that in addition four ladder orbit 5C all use ladder orbit 5C of the present invention, but incite somebody to action the difform ladder orbit 5 of several uses wherein, and the situation that makes up to use.
As shown in Figure 4, as the structure that the ladder orbit is installed on framework, consider following structure: will insert the peristome 17 that the bolt 22 that leads in the bolt hole that is opened in framework 21 passes the ladder orbit, and utilize bolt head and nut to carry out ladder orbit and framework clamping fastening.In addition, (b) is from frame side in Fig. 4, and namely peristome 17 sides are observed the figure of the installation example of (a) expression.Shown in Fig. 4 (b), in the structure of this ladder orbit 5C, because can be at the optional position of peristome 17 hold-down bolt 22, so the change of the installation site of bolt 22, that is, ladder orbit 5C is very easy to the adjusting of the position that framework 21 is installed.In this installation constitution, owing to be connected with framework 21 in peristome 17, so peristome 17 is restrained by bolt 22 etc.5C arranges peristome 17 at the ladder orbit, though itself can reduce the rigidity of ladder orbit 5C, by retraining peristome 17 with bolt 22 grades, can improve the bending stiffness of ladder orbit 5C.Therefore can be raw MAT'L with the thin material of the existing material of thickness ratio, and can realize lighting.In addition, existing escalator for example just must change specification and design paper when the floor height of building changes, but by being made as the structure that Fig. 4 represents, only change the length of ladder orbit 5C, just can deal with all ladder orbit 5C by enough design papers.
Next, the embodiment of the manufacture method of conveyer of the present invention is described.
At first, Fig. 5 has the cross sectional shape of Fig. 2 (c) expression as making, and end wise has the example of method of the ladder orbit 5C of length, the situation of expression Bending Processing.(a) expression operation 1, (b) expression operation 2, (c) expression operation 3, (d) expression operation 4, (e) expression operation 5, (f) represent operation 6 among Fig. 5.Ladder orbit 5C makes by a panel beating 8 is carried out bending according to the order of from (a) to (f) graphic operation 1～6.Become straight line 14,15,16 face portion when forming from cross-section by bending.The bending operation that Fig. 5 represents is an example only, and crooked order also needn't be defined in this order.
Fig. 6 is the example that is illustrated in the shape of bending part in the Bending Processing that Fig. 5 represents.When ladder orbit 5C was made in panel beating 8 bendings, bending part 12 in order to carry out roughly 180 ° bending, shown in Fig. 6 (a), carried out bending machining by giving R, thereby the intensity that can prevent bending part reduces.In addition, shown in Fig. 6 (b), 180 degree of also can turning back carry out bending, and bending part 12 can not have R in this case.
In addition, as another embodiment of the manufacture method of conveyer of the present invention, also have based on the manufacturing of extrusion process and make method as the ladder orbit of long parts.Fig. 7 is illustrated in an example of the cross sectional shape of this situation downstairs orbit 5C.As shown in Figure 7, different with the situation of utilizing bending machining to make, will straight line 14 and straight line 15 be shaped separately (being formed separately).Be equivalent to straight line 14 and straight line 15 at Fig. 7 cathetus 18.Bending Processing and extrusion process are examples that the long parts with such cross section is carried out method for processing, it is also conceivable that methods such as rolling, rolling formation, roll-in manufacturing in addition.
Next, as the manufacture method of conveyer of the present invention, the example of common roll-in bend mode is described.At this moment, the device integral body of all not drawing among all figure, the position that only records roller 31 concerns.In such roll-in bending machining, performance is applied the roller 31B (pinch roll) of the roller 31A (mobile roller) of the effect of bending machining power and the performance effect of pressing and make up and need more than three for minimum two kinds.
Fig. 8 is as the example of its minimum form, three bending machining is shown with the collocation method of rollers (below, be called for short " roller ") 31.At this moment, because the ratio of the quantity of the different mobile roller 31A of bending method and pinch roll 31B is different, only example of below representing.Represent to go into the moving direction that the adjustment of amount is moved the rotation axis of roller 31 in order to carry out roll-in with the arrow 510 of linearity, represent the hand of rotation (in Fig. 9, Figure 10 too) of driven roller 31 with circular-arc arrow 520.In the configuration of the roller shown in Fig. 8, at first under the situation of (a) graphic configuration mode, roller is configured to centered by mobile roller 31A two pinch roll 31B are arranged on the equicrural triangle of side.That is, at its center configuration rotation mobile roller 31A freely, dispose two pinch roll 311B, 312B altogether in its side.By making mobile roller 31A move to carry out the adjustment that amount is gone in roll-in to moving direction 510, in addition by making pinch roll 311B, 312B to hand of rotation 520 rotations, and make machined material 32 mobile or reciprocal at the length direction of machined material 32, carry out bending machining thus.Under the situation of the graphic configuration mode of Fig. 8 (b), any one among rotation mobile roller 311A, the 312A freely that pinch roll 31B is configured to make it and be configured in both sides approaches.Machined material 32 is clamped in pinch roll 31B on one side and carries out bending machining near one side between the mobile roller 312A of side.Roll-in is gone into the adjustment of amount and is carried out in moving direction 510 motions by making mobile roller 311A, 312A, by making pinch roll 31B to hand of rotation 520 rotations, make machined material 32 in the length direction movement of machined material 32 or back and forth carry out bending machining thus.Under the situation of Fig. 8 (c) graphic configuration mode, the configuration of three rollers 31 is the configurations with the same equicrural triangle of (a) graphic mode, but at central configuration rotation stationary roll 31D freely, be mobile roller 311A, the 312A of pinch roll 31B at its both sides configuration double as.By making mobile roller 311A, 312A to hand of rotation 520 rotations, make machined material 32 mobile at the length direction of machined material 32 on one side, independently in moving direction 510 motions, carry out going into respect to the roll-in of machined material 32 adjustment of amount thus on one side.Movement to the length direction of machined material 32 can be carried out to a direction continuously, also can back and forth carry out.In addition, machined material 32 is moved or reciprocal method at the length direction of machined material 32, nothing but an example, except the method by the rotational force of the friction force delivery roll 31 of 32 of roller 31 and machined materials, also the length direction of oriented machined material 32 applies the method for power.And then making machined material 32 can be whole bending machining with roller 31 at the mobile employed roller 31 of the length direction of machined material 32, and what also can be bending machining with in the roller 31 be several.
In Fig. 8 (a), (c), represented that the configuration of roller 31 is situations of equicrural triangle, but not necessarily must be equicrural triangle, under the situation of (a) graphic mode, also can consider mobile roller 31A near pinch roll 311B side, perhaps the situation of close pinch roll 312B side.In addition, similarly in (c), under the situation of graphic mode, also can consider the situation near mobile roller 311A or 312A side with stationary roll 31D.
Fig. 9 is another example of expression configuration of roller 31 when implementing the manufacture method of conveyer of the present invention by the roll-in bending.The example that Fig. 9 represents is that the quantity of roller 31 is the example under the situation more than four.Clamping machined material 32 disposes pinch roll 311B, 312B on thickness direction, disposes mobile roller 311A, 312A in the both sides of a pinch roll 312B.Adjustment with respect to the amount of being pressed into of machined material 32 is carried out in moving direction 510 motions by making mobile roller 311A, 312A and pinch roll 311B, 312B, make pinch roll 311B, 312B to hand of rotation 520 rotations, thereby make machined material 32 in the mobile bending machining of carrying out of the length direction of machined material 32.To the movement of the length direction of machined material 32, can carry out to a direction continuously, also can back and forth carry out.In addition, make machined material 32 at the mobile or reciprocal method of the length direction of machined material 32 example only, except the friction force by 32 of roller 31 and machined materials came the method for rotational force of delivery roll 31, also the length direction of oriented machined material 32 applied the method for power.And then making machined material 32 can be whole bending machining with roller 31 at the mobile employed roller 31 of the length direction of machined material 32, and what also can be bending machining with in the roller 31 be several.
Another example of the configuration of roller 31 when Figure 10 represents to implement the manufacture method of conveyer of the present invention by the roll-in bending.Figure 10 is equivalent in the roll-in bending when the quantity of the roller 31 that Fig. 9 represents is four, utilizes the example under the situation that roller 31 carries 32 of machined materials to a direction.In example shown in Figure 10, make the stationkeeping of any one party of mobile roller 311A, 312A that Fig. 9 represents, and play a role as guide reel 31C.Utilize pinch roll 311B, the 312B of 32 configurations of clamping machined material, machined material 32 limits in order to carry to correct direction from pressing with certain pressure up and down, support the conveying of this material with guide reel 31C, thereby carry out the roll-in bending machining by mobile roller 31A is moved at moving direction 510.While making whole roller 31 make machined material 32 carry out the processing of machined material 32 in the length direction movement of machined material 32 to hand of rotation 520 rotations.At this moment, the roller by changing pinch roll 311B, 312B at interval or mobile roller 31A to the amount of movement of moving direction 510, can change the curvature of bending thus.Make machined material 32 at the mobile method of the length direction of machined material 32 example only, except the friction force by 32 of roller 31 and machined materials came the method for rotational force of delivery roll 31, also the length direction of oriented machined material 32 applied the method for power.In addition, making machined material 32 can be whole bending machining with roller 31 at the mobile employed roller 31 of the length direction of machined material 32, and what also can be bending machining with in the roller 31 be several.
Next, the example of the roller 31 with the shape of rotating from the bight of outside constraint machined material 32 is described with reference to Figure 11.Figure 11 is illustrated in the manufacture method of conveyer of the present invention, be configured in ladder orbit 5C around the example of roll shape of pinch roll 31B.Figure 11 is the figure that observes from the face that the length direction with respect to ladder orbit 5C vertically intersects, though only put down in writing pinch roll 311B and 312B among the figure, but in the processing of reality, also use mobile roller 311A, the 312A that disposes before and after the length direction that leaves ladder orbit 5C as shown in Figure 9.The peristome 17 of machined material 32 is towards pinch roll 312B side.
As Figure 11 (a) was graphic, pinch roll 311B and 312B had the groove that bending machining is used at the position of each side that keeps ladder orbit 5C in its columned profile portion.This groove shape forms: in the middle of concentrated by the stress that produces in ladder orbit 5C in the inhibition bending machining, particularly the stress that produces in the bight is concentrated the shape of caused distortion.That is, pinch roll 312B suppresses its distortion with the bight 201 of the part clamping ladder orbit 5C of the part of straight line 102 and straight line 103, and suppresses its distortion with the bight 202 of the part clamping ladder orbit 5C of the part of straight line 103 and straight line 104.Pinch roll 311B suppresses its distortion with the bight 203 of the part clamping ladder orbit 5C of the part of straight line 105 and straight line 106 in addition, and suppress its distortion with the bight 204 of the part clamping ladder orbit 5C of the part of straight line 106 and straight line 107, and then, suppress the distortion on the L shaped long limit of ladder orbit 5C with the part of the part of the part of straight line 107, straight line 108 and straight line 101.
The long limit of the groove shape of pinch roll 311B and 312B and ladder orbit 5C and minor face measure-alike or bigger.By forming such shape, can be only retrain from the outside of roller 31 and do not retrain with tamper from the inboard of machined material 32, the generation that the stress when therefore suppressing easily by bending machining concentrates gauffer in reversing of causing or the face, buckle etc.
