Must be noted that, in this embodiment, the decline 11 of stent production line is downward-sloping relative to its rearmost part section (that is, the upper part 12 ' of chain 12 is downward-sloping).
In the decline 11 of production line, the separator 15 providing fabric and chain 12 and the telecontrol equipment making fabric movement after being separated with chain (or more generally, motion), thus fabric moves downward chain through production line, and be deposited on subsequently on the accumulation device 17 of below, this accumulation device 17 more clearly describes subsequently.
In this example, telecontrol equipment is formed by multiple element, in these multiple elements, is the roller 16D and the tractive cylinder 16E that return carrying roller 16A, 16B, 16C (preferably idler roller), have force cell; In this example, these elements 16 are in series arranged, to limit the path of fabric between separator 15 and accumulation device 17 according to following order: the first roller 16A is above the upper part 12 ' of chain 12; Second roller 12B is at the low portion 12 of chain 12 " below; There is the roller 16D of force cell at low portion 12 " below; 3rd roller 16C has below the roller 16D of force cell; And tractive cylinder 16E presses height placement between roller 16B and 16C.Naturally, the above-mentioned carrying roller and force cell roller and tractive cylinder of returning is provided with the parallel to each other and pivot center of motion vertical with fabric.Be appreciated that in other embodiments, this telecontrol equipment can be provided with different elements, and does not comprise the element mentioned all or some here.And the relative position of these elements can change as required.Be appreciated that this telecontrol equipment also can regard the assembly of the device that the fabric of separation (cut off or throw off) is turned to relative to the path in stent production line simply as downwards.
The device being used for fabric is moved downward also advantageously comprises protection dividing plate 16F ' and 16F "; these protections dividing plate 16F ' and 16F " is arranged to adjacent with the private side of corresponding chain 12, and be suitable for delimiting the space between same chain, this space enables fabric move downward, and does not touch the danger of chain; Therefore, from the inner side of production line to outside (transverse to production line), the layout of element is as follows: 1) chain, 2) dividing plate, 3) for the space, 4 of fabric movement) dividing plate, 5) chain.More particularly; this example is provided with first to protection dividing plate 16F ' and second couple of dividing plate 16F "; this first couple protection dividing plate 16F ' is placed side by side on inside the chain 12 of upper part 12 ', inside the chain 12 that this second couple of dividing plate 16F " is placed side by side on low portion 12 " (and therefore in dividing plate 12 ' below).
In this example, separator 15 is provided with two operator schemes.First mode provides being separated (path according to the fabric T of this first mode represents by continuous lines in FIG) of fabric and same needle by means of with the simple disengagement of pin forming fixture 14; In such configuration, fabric returns on carrying roller 16A first and guides (returning carrying roller 16A ' by preliminary cantilever).Second pattern provides cutting by means of knife unit 15A, this knife unit 15A is suitable for cutting the relative side direction (i.e. lengthwise) of the fabric T being fixed to two chains 12, and (the alphabetical L of line of cut indicates edge T1, and express with dotted line in the part of fabric T, this fabric T is expressed in fig. 2)., by the fabric T of cutting, from knife unit (fabric left from knife unit indicates with dotted line in FIG), through the first other roller 16A, " (being arranged in above the first roller 16A) guides downwards.
Protection dividing plate 16F ensure that fabric does not touch chain 12 when it moves downward, thus prevents fabric to be captured in by accident in same chain.As described; to throw off or the fabric T of cutting is being included in the upper and lower part 12 ' and 12 of chain " chain 12 between space in (namely through the end sections 11 of stent production line) be directed to second downwards and return carrying roller 16B; as indicated above, pass through protecting between dividing plate 16F.Fabric is partly wrapped in from the second roller 16B to be had the roller 16D of force cell, and then returns carrying roller 16C by the 3rd and transfer to tractive cylinder 16E, and the roller 16D of this force cell measures its tractive tension force.Tractive cylinder is cooperated with the roller 16D with force cell, to keep fabric tool tension force/tractive force likely.Their are formed and are used for measuring and adjustment to be left from stent production line and to enter the tension force (tractive force) of the fabric of accumulation device.
Above-mentioned accumulation device 17 is arranged in below tractive cylinder, and below the decline 11 of stent production line.According to the present invention, the accumulation device of fabric is arranged in below the decline of stent production line, and described decline is stacked on accumulation device at least in part.
In this embodiment, these accumulation devices 17 comprise accumulation surface 18, this accumulation surface 18 is movable according to arrow f2, be associated with the device making accumulation surface 18 can change its speed according to following at least two speed: first rate, at this first rate, surface 18 is with the movement velocity of the fabric T in the decline of stent production line (that is, substantially pressing the speed of stent production line) motion, corresponding with the proper motion step of stent production line; With the second speed, in this second speed, the movement velocity of the fabric of velocity ratio in the decline of stent production line on accumulation surface 18 is low, thus accumulation is formed in this on same surperficial 18, forms slight fluctuations.The direction of motion on surface 18 is consistent with the direction of motion of fabric T when it is on stent production line, or more generally, (its longitudinal end is represented by line N1 in FIG with the end sections 11 carrying out comfortable stent production line, corresponding with being returned the space outerpace that carrying roller 13 occupies by end in practice) longitudinal direction of below is consistent, in the outside of the projection of stent production line, preferably cross span N1, namely returns below carrying roller 13 in the end of production line and passes through.
In the example described, this accumulation surface 18 advantageously level.
According to preferred embodiment described herein, accumulation device 17 produces by means of the conveyer belt 19 of closed-loop type, and the upper face of this conveyer belt 19 is surperficial 18 corresponding with above-mentioned, and fabric T is accumulated on this upper face.This conveyer belt 19 is such as closed loop flexible-belt (or other flexible member), and this closed loop flexible-belt returns between carrying roller 20 at two and guides, and these two return one of carrying roller 20 is motor-driven.As mentioned above, the movement velocity of this belt surface 18 has at least two speed, one lower than the movement velocity of the chain 12 of stenter, and another is identical with the cardinal principle of the movement velocity during the normal operating of production line (namely, when fabric is collected in its downstream, as more clearly explained subsequently).
In a preferred embodiment, on conveyer belt 13, decline 11 stacked of stent production line is included in a part for the stent production line of the region upstream that fabric and chain are thrown off, although chain also continues their path after throwing off, until arrive end to return sprocket wheel 13.Term " upstream " or " downstream " refer to longitudinal direction, in fact with regard to the figure of Fig. 1 from left to right.
With reference to this Fig. 1, when being separated with chain by whole fabric wherein and occurring to throw off, throw off region to be marked by line N4, and (namely acquisition is measured S2 throwing off N4 " upstream " stacked on conveyer belt 19, comprise between online N4 and N3, and N3 identifies the line the space that occupied by band 19 in a longitudinal direction).
Same with reference to Fig. 1, when being occurred by the cutting at edge to be wherein separated, throw off region and marked by line N2, and S1 (namely between online N3 and N2) is measured in acquisition throwing off stacked on conveyer belt 19 of N2 " upstream ".
More generally, according to preferred embodiment, be stacked in " upstream " that online N1 occurs in any case according to of the present invention, namely line N1 limits the line of the maximum longitudinal space (returning the space outerpace that carrying roller 13 occupies by end) occupied by the decline of stenter.In the example described, stent production line is stacked on conveyer belt 19 to measure S3 (namely with the space comprised between N1 and N3).Must be noted that, conveyer belt in this example remains on outside stent production line to measure S4, and this amount S4 is included between N1 and N5, and N5 is the line of the end of the floor space of mark band 19 in a longitudinal direction.
In fact, in this example, the decline of stent production line is stacked at least 4/5 for the length of conveyer belt 19 on conveyer belt 19.Usually, this stacked at least half for conveyer belt occurs, and preferably occurs at least 3/4 of conveyer belt at least 2/3, even more preferably.Be appreciated that the length of conveyer belt is larger, the amount of the fabric of accumulation will be larger.Therefore, in other embodiments, this band also can extend until more core (that is, the sloping portion of the decline 11 of stent production line) with regard to the part indicated here below stent production line.
Therefore, according to top view, accumulation device (in this example, conveyer belt) be substantially included in below stent production line for its major part, namely with reference to the longitudinal extension part of this production line, its major part is included between the initial of stent production line and last longitudinal limit (such as, chain initial and latter two returns carrying roller).
This structure makes it is possible that the system that terminates on accumulation chute relative to wherein stent production line, reduces occupying of the space around stent production line.
