Definitions

  • the invention relates to a device for conveying a web of material in the form of long, narrow hanging loops through a treatment chamber, according to the corresponding preamble of patent claims 1 and 2.
  • bar chain conveyors have also been developed in which the support bars are attached to the chains at large intervals.
  • the support rods lie close together on a support element and move at low speed in the direction of the goods outlet.
  • the chains hang from the support bars when folded.
  • the rest of the orbit i.e. the return path, run through the chains at high speed in the stretched state. Examples of such devices can be found in DE-PS 22 42 890, in DE-OS 20 56 945 and in DE-OS 29 51 299.
  • the chain which is guided over a third sprocket arranged in the vicinity of the ceiling, places the support rod on a support element which is designed as an endless conveyor belt.
  • the conveyor belt rotates at a greatly reduced speed, so that the supporting bars lie close together on it and the chain sags in free loops.
  • the invention has for its object to avoid the disadvantages mentioned and to improve a device according to the preamble of claims 1 and 2 so that a uniform loop length is ensured.
  • the arm enables the support rod to move around the second sprocket at a distance on an arc in the loop formation area.
  • each support rod is gripped exactly at the prescribed point by a pivot lever.
  • the number of teeth of the second sprocket it is necessary to match the number of teeth of the second sprocket, the number of chain links between two supporting bars and the arrangement of the pivot levers.
  • various combinations are possible, which the person skilled in the art can easily calculate.
  • a structurally simple combination with favorable dimensions is specified in claim 3.
  • the length of the arm according to claim 4 results in a sufficient jump in speed with a small footprint.
  • the time at which the speed jump occurs depends on the relative position of the first and second sprockets. In the arrangement according to claim 5, there is a favorable time.
  • the pivot lever not only guides the support rod around the second sprocket, but at the same time raises the arm to which the support rod is attached, so that the support rod leads the associated hinge pin.
  • the feature of claim 6 ensures the exact further transport of the support rod.
  • the cam disc mentioned in claim 7 facilitates the rotation of the support rod around the third sprocket and its further transport to the support member and causes the defined feed of the support rods already there.
  • the feature of claim 9 enables the step-by-step feed of the loops carrying support rods with simple means.
  • each feed step is coupled with one revolution of all the support rods located on the rail. This avoids markings on the goods.
  • the rolling resistance becomes so great that the roll slips on the rail. The stick can no longer turn and the goods can develop again.
  • Figure 1 illustrates the orbit of a chain for a first embodiment.
  • FIG. 2 shows an enlarged section from FIG. 1.
  • FIG. 3 illustrates a detail from FIG. 1.
  • FIG. 4 illustrates another detail from FIG. 1.
  • FIG. 5 shows another detail in section.
  • Figure 6 illustrates the orbit of a chain for a second embodiment.
  • an endless chain 2 consisting of interlinked ring links runs in a closed orbit in a vertical plane. It is guided over several sprockets 3 - 8 of the same size. Between the two chains 2, support rods 9 extend, the ends of which are connected at regular intervals a to the two chains 2.
  • the distance a is e.g. 1 - 1.5 m. It is 1.5: 1 in relation to the circumference of the chain wheels 3 - 8.
  • this means that the number of chain links between two support rods is 3: 1 to the number of teeth on a chain wheel 3 - 8.
  • this relation is important at least for the sprockets 4, 5.
  • the support rods 9 are connected to the chain 2 by arms 10.
  • Each arm 10 is freely rotatable on a hinge pin 11 which is attached to a link of the chain 2.
  • an axle pin 12 of the support rod 9 is rotatably mounted in the other end of the arm 10.
  • a roller 13 is seated in a rotationally fixed manner.
  • the arm 10 has a pear-like shape: it widens in the direction of the support rod 12 and has a circular arc on the side facing away from the hinge pin 11 13 coaxial contour, the radius of which is slightly larger than the radius of the roller 13.
  • the length of the arm 10, measured between the axis of the pivot pin 11 and the axis of the support rod 9, is equal to half the effective diameter d of the chain wheels 3-8.
  • the support rods 9 are arranged closely next to one another so that the widened ends of the arms 10 abut one another. Accordingly, the center distance of adjacent supporting rods is e.g. about 10 - 15 cm.
  • the rollers 13 are supported on support members which are designed as rails 14.
  • the arms 10 hang freely down.
  • the chain 2 forms a hanging loop 15 between the hinge pins 11 of each two adjacent arms 10.
  • the chain 2 is between the individual sprockets in the stretched state.
  • the chain wheels 5, 6 which are directly adjacent to the two ends of the rail 14 can be driven synchronously at a constant speed.
  • the direction of rotation is symbolized in the drawing by an arrow 16.
  • the sprocket 3, hereinafter referred to as "first sprocket” for better distinction, is arranged under a feed roller 17 so that its axis lies almost in the vertical tangential plane of the feed roller 17 on the outlet side.
  • the "second sprocket" 4 is arranged at the same height next to the first sprocket 3.
  • the center distance of the chain wheels 3, 4 is approximately 1.5 times the effective diameter.
  • the chain 2 is S-shaped over the two sprockets 3, 4, looping around the first sprocket 3 from above and the second sprocket 4 from below. Between the two chain wheels 3, 4 there is an obliquely downward section.
  • Fixed to the second sprocket 4 is a two-armed pivot lever 18.
  • the length of a lever arm 19, 20 is equal to the sum of the effective radius of the second sprocket 4 and the length of the arm 10, i.e. in the present embodiment, the effective diameter of the sprockets.
  • each lever arm 19, 20 On the leading side in the direction of rotation, each lever arm 19, 20 has a hook-like projection 21, 22 at the end.
  • the "third sprocket" 5 is arranged on the side facing away from the first sprocket 3 obliquely above the second sprocket 4 so that the chain 2 alternately loops around the two sprockets 4, 5 and passes between them a vertically directed straight line section.
  • a cam disk 23 Connected to it in a rotationally fixed manner is a cam disk 23 which has two recesses 24, 25 which are offset by 180 ° and match the outline of the arm 10 and is arranged in the same plane as the arm 10.
  • a material web 28 is fed from below to the feed roller 17 through a slot 29 in the bottom of the treatment chamber.
  • a support bar of the chain run 2a moved vertically upwards has just reached the position 9a at a certain moment.
  • the associated arm hangs down in position 10a on its hinge pin, which is located on the first sprocket 3 in the 9 o'clock position 11a.
  • the material web has not yet touched the support rod.
  • a new loop can be formed undisturbed.
  • the hinge pin has passed the outlet-side vertical tangential plane of the feed roller 17 and is in the 1 o'clock position 11b.
  • the support rod has moved to position 9b on an arcuate curve. He is now in contact with the nascent loop 28b, which is in the process of being formed and rests on the one hand on the feed roller 17 and on the other hand on the leading support rod 9m. This slips on the support rod and deflects it - depending on the weight of the goods - a little to the side, so that the associated arm assumes an oblique position 10b. In an intermediate position 9c, 10c, 11c, the lateral deflection due to the lengthening hanging loop 28c is already greater.
  • the hinge pin now moves on an inclined downward path. The support rod moves approximately parallel to it. However, since it is deflected more and more by the hanging loop that slides on it, its movement is somewhat slowed down compared to the movement of the associated hinge pin.
  • the hinge pin now reaches the 8 o'clock position lld on the second sprocket 4.
  • the arm assumes an approximately radial position 10d. At about this moment, it is gripped by the arm 19 of the swivel lever 18 and guided around the second sprocket 4 at a distance on the flight circle 27. It is suddenly accelerated to twice the chain speed. Due to the acceleration, the contact force between the web and the support bar is currently increased. At the same time, the wrap angle between the support bar and the web increases. In the 6 o'clock position 9e it is approximately 90 °.
  • the support rod is prevented from rotating about its axis by the frictional contact with the arm 19 of the pivot lever 18. The goods can therefore neither slip nor roll off.
  • the loop has ended.
  • the delivered goods begin to form a new loop.
  • the arm While the support rod is guided counterclockwise onto the flight circle 27 by the pivot lever 18, the arm maintains its approximately radial position so that it is almost upright in the 1 o'clock position 10f (FIG. 3). In this position, the roller 13 runs into the guide rail 26, which now takes the lead. The support rod is thereby released from the pivot lever 18. In position 9g the support rod is located exactly vertically above the associated hinge pin llg. A moment later, the cam plate 23 engages the arm and moves it to the horizontal position 10h (FIG. 4). Its widened end, in which the support rod 9h is mounted, has already reached the rail 14 and abuts the support arm 10n of the leading support rod 9n. In position 10h, the arm acts as a push rod which moves the support rod 9n and the further support rods already on the rail 14 one step further forward.
  • the length of the steps corresponds to the diameter of the arcuate contour at the wider end of the arm 10.
  • the rollers 13h, 13n of the support rods 9h, 9n have no contact with one another and can therefore roll freely on the rail 14. This also applies to the roles of the other support rods that are already on the rail 14. Each roll rotates around 120 ° per step. Accordingly, the support points of the fabric loops hanging on the rollers are shifted with each step, so that markings are avoided.
  • the second sprocket 4 Because of the coordinated size relationship between the support rod distance and the circumference of the sprocket, the second sprocket 4 has made exactly 1.5 revolutions when the subsequent support rod has reached position 9d.
  • the support rod is therefore detected at the right moment by the other arm 20 of the pivot lever 18.
  • the recesses 24, 25 of the cam plate 23 alternately engage the arms 10 of successive support rods 9.
  • a take-off roller 30 arranged above the end of the rail 14 has pulled out the product loop hanging between it and the subsequent support rod.
  • the driven chain wheel 6 pulls off the chain loop 2z hanging between it and the hinge pin located in position 11z. Finally, the position of the chain 2 is pulled onto the chain wheel 6 at which the hinge pin 11z is seated.
  • the associated support rod is pulled off the rail 14 and transported, hanging vertically downwards.
  • FIG. 6 the same reference numerals have been used for those details which structurally and functionally essentially correspond to details of FIG. 1 as in FIG. 1. In this respect, a description is unnecessary.
  • the arm 50 which connects the support rods 59 to the chain 2 is rigidly connected to the associated chain link 51, in such a way that it points inwards at right angles. Its length corresponds exactly to half the effective diameter of the chain wheels 3 - 8.
  • the loop is formed as follows: At a certain moment, a chain link has just reached the 9 o'clock position 51 a on the first chain wheel 3. The associated arm is in the horizontal position 50a and the support rod in position 59a. In this position, its axis coincides exactly with the axis of the first sprocket 3. The support rod remains in this position, while the associated chain link on the first chain wheel 3 passes through an arc of approximately 120 °. During this period, the entire space between the feed roller 17 and the leading support rod is available for the formation of a product loop. After the chain link has passed the 1 o'clock position 51b, it moves in a straight line on the downward inclined path via the intermediate position 51c to the position 51d. The support rod passes through the corresponding positions 59c, 59d at the same speed as the chain link.
  • the chain link then describes an arc counterclockwise on the second sprocket 4, which extends approximately from the 8 o'clock position to the 3 o'clock position.
  • the support rod also runs through an arc, but with a double diameter. During the transition to the bow, it is suddenly accelerated to twice the speed. From this moment on, as explained in detail in connection with the other exemplary embodiment, the goods can no longer slide off the support rod. The following goods start to form a new loop.
