The conveyer of conveyer of the present invention is represented as block diagram in Fig. 3 with the example of the crooked state of ladder orbit 5C.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 that ladder 4 uses 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 the structure that moves on any limit in the face of straight line 16.Therefore through bending direction being changed into the arbitrary 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 crooked example of direction of curved interior with ladder orbit 5C; (b) conveyer that illustrates is to making peristome 17 become the crooked example of direction of curved outside with ladder orbit 5C; (c) conveyer that illustrates is to making long side become the crooked example of direction 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 to conveyer of the present invention, and the figure of its ladder orbit to the example of framework installation is shown.(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 is provided with the 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) representes it example is installed.As install towards; As an example of expression among Fig. 4 (a); In four ladder orbit 5C; Several are mounted in long side operation, and remaining several situation 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 the situation in the short brink operation.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 make up situation about using.
As shown in Figure 4; As the structure that the ladder orbit is installed on framework; Structure below considering: 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 promptly 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 since can be in the optional position of peristome 17 hold-down bolt 22, so 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 in peristome 17, be connected with framework 21, so peristome 17 is restrained by bolt 22 etc.On ladder orbit 5C, peristome 17 is set,,, can improves the bending stiffness of ladder orbit 5C through with peristome 17 such as constraint such as bolt 22 grades though itself can reduce the rigidity 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 through being made as the structure that Fig. 4 representes; 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 manufacturing approach 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 through a panel beating 8 is carried out bending according to the order of from (a) to (f) graphic operation 1～6.Become the face portion of straight line 14,15,16 when forming from cross-section through bending.The bending operation that Fig. 5 representes 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 representes.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 through 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 manufacturing approach 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 manufacturing approach 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 (move roller) of the effect of bending machining power and the effect that performance is pushed and make up and need more than three for minimum two kinds.
Fig. 8 is as the example of its minimum form, and the collocation method of three bending machining with roller (below, be called for short " roller ") 31 is shown.At this moment because that the difference of bending method moves the ratio of quantity of roller 31A and pinch roll 31B is different, below represent nothing but an example.Represent to go into the moving direction that the adjustment of amount is moved the rotation axis of roller 31 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 order to carry out roll-in.In the configuration of the roller shown in Fig. 8, at first under the situation of (a) graphic configuration mode, it is the equicrural triangle that the center is arranged on two pinch roll 31B the side that roller is configured to move roller 31A.That is,, dispose two pinch roll 311B, 312B altogether in its side at its center configuration rotation mobile roller 31A freely.Through being moved to moving direction 510, mobile roller 31A carries out the adjustment that amount is gone in roll-in; In addition through making pinch roll 311B, 312B to hand of rotation 520 rotations; And make machined material 32 mobile or reciprocal on the length direction of machined material 32, carry out bending machining thus.Under the situation of the graphic configuration mode of Fig. 8 (b), with pinch roll 31B be configured to make its with freely mobile roller 311A of the rotation that is configured in both sides, 312A in any one approaching.On one side machined material 32 is clamped in pinch roll 31B 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 on moving direction 510, is moved and carry out through making mobile roller 311A, 312A; Through making pinch roll 31B, machined material 32 is moved on the length direction of machined material 32 or back and forth carry out bending machining thus to hand of rotation 520 rotation.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, be mobile roller 311A, the 312A of pinch roll 31B at its both sides configuration double as at central configuration rotation stationary roll 31D freely.Move roller 311A, 312A to hand of rotation 520 rotations through making; Machined material 32 is moved on the length direction of machined material 32 on one side; Motion on moving direction 510 independently carries out going into respect to the roll-in of machined material 32 adjustment of amount thus on one side.Moving of length direction to 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 on 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, the length direction of also oriented machined material 32 is executed power-assisted method.And then, make machined material 32 on the length direction of machined material 32, move employed roller 31 can be whole bending machining with roller 31, 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 situation of equicrural triangle; But not necessarily must be equicrural triangle; Under the situation of (a) graphic mode, also can consider to move roller 31A near pinch roll 311B side, perhaps near the situation of pinch roll 312B side.In addition, likewise in (c), under the situation of graphic mode, also can consider stationary roll 31D near the situation that moves roller 311A or 312A side.
Another example of Fig. 9 configuration of roller 31 when to be expression through the roll-in bending come the manufacturing approach of conveyer of embodiment of the present invention.The example that Fig. 9 representes 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, moves roller 311A, 312A in the configuration of the both sides of a pinch roll 312B.Adjustment with respect to the amount of being pressed into of machined material 32 is moved roller 311A, 312A and pinch roll 311B through making, 312B moves on moving direction 510 and carries out; Make pinch roll 311B, 312B to hand of rotation 520 rotations, carry out bending machining on the length direction of machined material 32 thereby machined material 32 is moved.To moving 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 on the length direction of machined material 32, move only example of perhaps reciprocal method; Except the friction force by 32 of roller 31 and machined materials came the method for rotational force of delivery roll 31, the length direction of also oriented machined material 32 was executed power-assisted method.And then, make machined material 32 on the length direction of machined material 32, move employed roller 31 can be whole bending machining with roller 31, what also can be bending machining with in the roller 31 be several.
Another example of the configuration of roller 31 when Figure 10 representes to come the manufacturing approach of conveyer of embodiment of the present invention through the roll-in bending.Figure 10 is equivalent in the roll-in bending when the quantity of the roller 31 that Fig. 9 representes is four, utilizes roller 31 with 32 examples under the situation that a direction is carried of machined material.In example shown in Figure 10, make any side's of mobile roller 311A that Fig. 9 representes, 312A stationkeeping, 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 so that carry to correct direction from pushing with certain pressure up and down; Support the conveying of this material with guide reel 31C, thereby carry out the roll-in bending machining on moving direction 510 through mobile roller 31A is moved.While making whole roller 31 make machined material 32 on the length direction of machined material 32, move the processing of carrying out machined material 32 to hand of rotation 520 rotations.At this moment, the roller through 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 only example of method that machined material 32 moves on the length direction of machined material 32; Except the friction force by 32 of roller 31 and machined materials came the method for rotational force of delivery roll 31, the length direction of also oriented machined material 32 was executed power-assisted method.In addition, make machined material 32 on the length direction of machined material 32, move employed roller 31 can be whole bending machining with roller 31, what also can be bending machining with in the roller 31 be several.
Next, the example of the roller 31 of the shape with the bight rotation that retrains machined material 32 from the outside is described with reference to Figure 11.Figure 11 is illustrated in the manufacturing approach 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, mobile roller 311A, the 312A that disposes before and after the length direction that leaves ladder orbit 5C that also use 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: suppress in the bending machining by in the middle of the stress concentration that in ladder orbit 5C, produces the shape of the caused distortion of stress concentration that particularly produces in the bight.That is, pinch roll 312B suppresses its distortion with the bight 201 of the part clamping ladder orbit 5C of the partial sum straight line 103 of straight line 102, and suppresses its distortion with the bight 202 of the part clamping ladder orbit 5C of the partial sum straight line 104 of straight line 103.Pinch roll 311B suppresses its distortion with the bight 203 of the part clamping ladder orbit 5C of the partial sum straight line 106 of straight line 105 in addition; And suppress its distortion with the bight 204 of the part clamping ladder orbit 5C of the partial sum straight line 107 of straight line 106; 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.Through 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 stress concentration when therefore suppressing to be prone to by bending machining causes reverse or face in gauffer, the generation of buckling etc.
Illustrate the different example of the roll shape (pinch roll 312B) of peristome 17 when pinch roll 312B side in Figure 11 (b).In (a) of Figure 11, in the graphic roller 31, further on the pinch roll 312B of peristome 17 sides that are disposed at ladder orbit 5C, be provided with flange shape projection as a kind of mode that suppresses the peristome shut-off block.This projection gets into the peristome 17 of ladder orbit 5C, thereby peristome 17 is closed when suppressing rolling formation.At this moment; Can suppress the projection that the peristome 17 of ladder orbit 5C is closed; Be the outstanding projection in bottom of the groove that in Figure 11, forms from part, be meant the projection that the part by the part of the part of straight line 112, straight line 113 and straight line 114 forms by straight line 111,115.
Next, another embodiment of the manufacturing approach of conveyer of the present invention is described with reference to Figure 12.Figure 12 illustrates the different example that is configured in machined material 32 roll shape on every side.Figure 12 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, in the processing of reality, also uses and moves roller 311A, 312A.In Figure 12 split shed portion 17 towards with respect to the vertical direction of moving direction that moves roller 31A.Pinch roll 311B and 312B have 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: suppress in the bending machining by in the middle of the stress concentration that in ladder orbit 5C, produces the shape of the caused distortion of stress concentration that produces in the particularly bight of ladder orbit 5C.Part with the straight line 123 of the part of the part of the straight line 121 of pinch roll 312B, straight line 122 and pinch roll 311B; The bight 201 of clamping ladder orbit 5C suppresses its distortion; And the bight 202 with the part clamping ladder orbit 5C of the partial sum straight line 124 of the straight line 123 of pinch roll 311B suppresses its distortion; Bight 203 with the part clamping ladder orbit 5C of the partial sum straight line 125 of the straight line 124 of pinch roll 311B suppresses its distortion in addition; Bight 204 with the part ladder support orbit 5C of the partial sum straight line 126 of the straight line 125 of pinch roll 311B suppresses its distortion, and the part of the part of the straight line 126 of this external application pinch roll 311B, the straight line 127 of pinch roll 312B and the part of straight line 121 suppress the distortion on the long limit of L shaped shape.
