Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a web gathering and guiding device in a carding machine. An apparatus comprising a guide element having a guide surface extending perpendicular to the direction, that is, transverse to the traveling direction of the fiber web surface, and which takes the web from the web take-up mechanism and collects it into a fiber bundle. It is.

In the guide device known from U.S. Pat. No. 3,946,464, the guide element consists of at least two conveyor belts, the tensioned parts of the individual belts in contact with the dosing or feeding mechanism running opposite each other. In this device, the guide element has at least one movable guide surface. Therefore, the conveyor belt must run over driven rollers, which can result in operational failures. Moreover, the belt must be kept tensioned at all times, which adds to maintenance costs. Overall, the installation costs of this known device are too high. Furthermore, since the guide surface of the conveyor belt is flat, there is a disadvantage that the air flow acts directly from above to below against the web fed from the feeding mechanism. This drawback is particularly problematic when the web is fed out of the feed mechanism at high speeds.

In the web guide device known from U.S. Pat. No. 3,196,492, the web is delivered from a web removal mechanism of a carding machine and is supported by a guide surface. This device is connected to the card dock and extends to a pair of calender rolls. That is, an asymmetrically configured flat triangular guide plate having upwardly curved edges serving as left and right web guide means is disposed between the take-out mechanism and the calender roll. The slightly downwardly inclined longitudinal edge of the edge forms an acute angle with the axis of the web take-out roller, so that the entire apparatus takes on a funnel-like shape. Between the left and right edges, the web guide device opens upwards, so that the web sliding on the guide plate is acted upon by an air flow from above, which causes the web to move upwards, especially when being fed at high speeds. There is a possibility of escape. As is well known, a web delivered at a high velocity must be focused at an equally high velocity.
Furthermore, when sliding on the guide plate, there is a possibility that the web may stagnate or break due to local differences in adhesive force, which will affect the production flow and quality. With this known device, it is not possible to capture and focus webs delivered at high speeds.

No. 3,840,942 discloses a web guiding device comprising a pair of guiding elements spaced apart from each other on both sides of the web fed out from a squeeze roller.
It is known from No. A control device causes the guide element to
The webs are moved from an lateral position where there is no compressive occlusion to an internal position where the webs converge into a generally T-shaped bundle. Since both guide elements are much shorter than the squeeze roller, the squeeze roller is required to capture all the web coming out of the squeeze roller.
It must be placed a certain distance from the roller. If the web is arranged in this way, the web will be strongly affected by the air current, and if the speed of the web is increased, there is a risk that the web will be cut. Therefore, such an arrangement cannot be used.

SUMMARY OF THE INVENTION In order to eliminate the above-mentioned drawbacks, an object of the present invention is to provide a web convergence guide device that can reliably capture and condense webs fed out from a feeding mechanism at high speed with an extremely simple structure. be.

According to the invention, unlike the above-mentioned known devices, a web guiding device which requires no maintenance and operates without any troubles can be produced very simply and economically, if the guiding element is provided with at least one stationary guiding surface. Can be manufactured. An important advantage is that there are no longer moving parts such as rollers, belts, etc. The guide surface of the guide element is constructed in such a way that it is concave in the direction of the web in order to accommodate the passing web. With this arrangement, the airflow does not act on the focused web. With the apparatus of the present invention, the problem of reliably capturing and simultaneously focusing a web fed at high speed can be solved very easily. The air flow in the guide surface rolls up the edges of the web, thus stabilizing the web as it passes. Another advantage of the apparatus of the present invention is that the orientation of the fibers constituting the web is well maintained.

In contrast to the second known device mentioned above, in the present invention the web strikes the guide surface of the guide element almost perpendicularly from the feeding mechanism and moves within the guide surface with a perpendicular orientation. By covering the working peripheral surface of the roller of the supply mechanism on the delivery side with the guide surface of the guide element,
The web is protected from the influence of the outside air and, by being guided in the manner described above, is restrained from escaping upwards. The speed at which the web is removed from the rollers and the speed at which it is delivered via the guide element is therefore the same. It is believed that the delivery speed of the web moving within the guide surface is increased by the air flow delivered from the feed mechanism. It is believed that the inward curling phenomenon at the edge of the web is also caused by the air flow flowing within the guide surface, and this provides stability of the web.

In contrast to the third known device mentioned above, the guide elements are arranged close to the rollers, the concave guide surfaces develop in a direction perpendicular to the direction of travel of the web to be delivered, and the delivery side circumferential surfaces of both rollers are arranged close to the rollers. covered by a concave guide surface. Since the guide surface is in close proximity to the rollers that feed the web, the web is not affected by the outside air. The web leaving the squeeze roller has an extremely thin veil-like structure and is susceptible to breakage. In the present invention, the web is focused as soon as it leaves the squeeze roller,
Both edges are folded inward, so you don't have to worry about it breaking even when driving at high speeds. In particular, for thin webs made of short fibers, the running speed has been increased from about 60 meters per minute to about 80 meters per minute, and for thick webs made of medium or long fibers, the running speed has been increased from about 150 meters per minute to about 150 meters per minute. It can accelerate up to about 210 meters. According to the results of practical use, the apparatus of the present invention, which has an extremely simple structure, has extremely easily achieved the task of reliably capturing and simultaneously converging webs fed at high speed. By using the apparatus of the present invention, even short fibers called waste generated when carding cotton fibers can be processed. In the known apparatus, short fibers have a weak cohesive force, so the web is easily broken. In the present invention, even if the cohesive force is not strong, the web is converged as soon as it leaves the squeeze roller, the web is folded inward from both edges, and is drawn out as a card sliver.

It is preferable that the horizontal longitudinal edge of the guide surface of the guide element is parallel or substantially parallel to the axis of the roller of the supply mechanism, and that the guide surface covers the delivery-side circumferential surfaces of both rollers of the supply mechanism. Placing this longitudinal edge in close proximity to the rollers of the feed mechanism prevents air flow from adversely affecting the web. The apparatus of the present invention can be easily manufactured by arranging the longitudinal edge of this guide surface parallel to the roller axis of the supply mechanism.

In order to facilitate the web welding operation, it is preferable that this guide surface is movable in the running direction of the web while maintaining a parallel arrangement with respect to the roller axis of the supply mechanism. Similar advantages can also be obtained by configuring the guide surface of the guide element to be able to rotate while maintaining the holding level (with respect to the roller axis of the supply mechanism). That is, with this configuration, abnormalities such as variations in fiber density and disturbances in fiber orientation in the web can be observed while the web is captured and focused, thereby controlling the mode of operation of the card.

In order to configure the guide surface so that it has a concave shape in the direction of the web pulled out from the roller of the feeding mechanism, it is sufficient to select a concave shape such as a cylindrical shape, a flat arc shape, or a prismatic shape. Depending on the feed rate and the number of webs, a shape that is hydrodynamically and technically suitable will be selected.

Either two fiber strips are drawn out from the side edges of the guide surface of a one-piece guide element, two outlets are provided on the guide surface of a one-piece guide element, or three are arranged side by side.
The web can be split by providing two outlets, for example gaps, to capture the two webs between two guide surfaces.

It is practical to provide at least one outlet in the guide surface of the one-piece guide element in the form of a hole or a recess opening either upwardly or downwardly.

The web can also be pulled out reliably by forming a hole with rounded corners or a notch opening to one side, especially near the side edges of the guide surface of the guide element.

If both guide surfaces of a two-component guide element are pivotable about an axis perpendicular to the horizontal part of the machine frame, or if the integral guide element is movable in the direction of web travel, then The guide surface of the guide element is pulled away from the rollers of the feed machine to open it, and the web is then spliced before being fed through the trumpet to the calender rollers.
This guide surface may then be returned to its working position in close proximity to the rollers of the feeding mechanism, and the web withdrawal speed may be accelerated to, for example, 250 meters per minute or more. In this operating position, the generatrix of the guide surface is parallel to the axis of the roller of the feed mechanism. During operation, the web can be observed by rotating or shifting this guide surface while adjusting the operating speed.
However, depending on the material to be processed, the feeding speed, and the web count, the generatrix of the guide surface may be left at an acute angle or offset from the axis of the roller of the feeding mechanism.

If the guide element is configured to be movable parallel to the axis of the roller of the supply mechanism, a large space is secured for joining the webs and controlling the operation, and therefore the operation becomes easier.

If the guide surface of the guide element almost completely covers the delivery side circumferential surface of the roller, it is possible to prevent the adverse effects of air currents acting on the web from the outside.

Preferably, the guide surface of the guide element is arranged such that its generating line forms an angle with the axis of the roller, while the horizontal upper and lower longitudinal edges of the guide surface are very close to the roller.

The side edge of the guide element is connected to one of the rollers of the supply mechanism.
If the trumpet-shaped web guide member and the calendar roller are arranged to be located inward from the end face on one side, the trumpet-shaped web guide member and the calender roller should be provided at positions along one side of the carding machine in correspondence with the position of the side edge of the guide element. The purpose of the present invention can be achieved by the following.

The basic structure of the web converging and guiding device in a carding machine according to the present invention has been described above.Next, the basic structure of the device of the present invention and its effects will be explained with reference to the embodiments shown in the attached drawings. will be explained in detail.

As is clear from FIG. 1, the cylinder 1 of the carding machine 2 includes a dot arrow roller 3, a stripper roller 4, squeeze rollers 5, 6 as a feeding mechanism, and a trumpet-shaped web guide member 7 (hereinafter simply referred to as trumpet). ) are installed in parallel. A guide element 8 is provided immediately behind the squeeze rollers 5,6. The guide surface 10 of the guide element 8 is formed to be a semi-cylindrical concave surface toward the web 9 emerging from the squeeze rollers 5,6. Information surface 10
is configured to remain stationary at least during operation and cover the delivery side peripheral surfaces of both squeeze rollers 5 and 6. The upper and lower longitudinal edges of the guide surface 10 (not shown in FIG. 1) are on the same level as the upper and lower peripheral edges of the squeeze rollers 5 and 6, respectively. The guide element 8 is fixedly arranged, but can be pivoted about a vertical axis via a pivot element, for example a hinge (not shown in FIG. 1), near the side edge of the curved shape. can.

During operation, the web 9 coming out of the squeeze rollers 5 and 6 collides with the guide surface 10 and is rolled up into folds. As a result, the web 9 is collected and pulled out in the direction determined by the web joining. The collected web 9 is guided by a guide surface 10, for example along a cornered side edge of the guide element 8, into the trumpet 7 and is focused into a sliver 11.

Figures 2, 3 and 4 show various embodiments of guide elements 8a, 8b and 8c and respective associated squeeze rollers 5, 6. FIG. 2 shows a guide element 8a consisting of two flat plate parts joined at a position remote from the squeeze rollers 5,6. This embodiment is easy to manufacture since it consists of flat plates joined at one joint line. The configuration of the guide element 8b illustrated in FIG.
Two flat plate parts are assembled at an angle to each other. With this configuration, the four flat plate portions can provide a relatively wide space. The guide element 8c shown in FIG. 4 has a flat arc-shaped cross section. This guide element 8c is connected to the moving element 28 via the holder 27.
The moving element 28 allows the guiding element 8c to be moved toward and away from the squeeze rollers 5, 6 along the rail 29. Since it has a flat arc shape, the web can be guided particularly smoothly. The guide elements 8a, 8b and 8 described above
c are both open toward the squeeze rollers 5 and 6 so that the web 9 can be stored in their bosoms.

Figures 6a and 6b show a guide element 8e of integral construction. A slit 23 that opens upward on only one side is formed near the center of the guide element 8e.
This slit 23 is U-shaped, and its edge is constituted by a rounded shoulder 26. The advantage of this slit 23, which is open only on one side upward, is that the webs of the card can be supported and the webs can be joined easily.

The embodiment shown in FIGS. 7a and 7b is similar to the embodiment shown in FIGS. 6a and 6b, except that the guide element 8f is formed by a slit 2 that opens only downwardly.

As is clear from figure b, the guide surfaces 10i and 10
The generatrix of i' forms an acute angle with the longitudinal axes of the squeeze rollers 5, 6, and is arranged to approach the axes of the squeeze rollers 5, 6 towards their ends. This embodiment provides a large space for accommodating the web, so it is suitable especially when the card sliver is thick.

Figures 15a and 15b show a one-piece guiding element 8p which effectively accomplishes the splitting of the web by guiding the two-part web along the rounded side edges 12p, 13p.

16a and 16b are similar to the embodiment shown in FIGS. 15a and 15b, but the radius of curvature of the outer edges 12r and 13r is larger than the radius of curvature of the guide surface 10r in the intermediate region between the side edges 12r and 13r. A one-piece guide element 8r is shown.

In the embodiments shown in FIGS. 14a to 16a and 14 to 16b, the web can be split so that more than one card sliver can be drawn out. Particularly when the working width of the carding cylinder is greater than one meter, it is advantageous to be able to divide the web.

As described above, the web converging and guiding device of the present invention includes rollers,
In particular, an embodiment has been described in which the feed mechanism is linked with squeeze rollers 5 and 6, but it is of course possible to link with other web drawing devices.

When the above-described web converging and guiding device for a carding machine was put into practical use, it became desirable to provide a trapping means in order to solve various practical problems. Below, these retrieval means and the web focusing and guiding device equipped with them will be explained in sequence.

The first problem is what to do when cutting the web.
That is, there is a possibility that a part of the web supplied from the supply mechanism, that is, the web take-out mechanism may be interrupted, that is, it may be cut off at a certain position. The cut web is completely pulled out by the pull-out roller of the calendar mechanism. The subsequently fed web loses its connection with the drawing roller and can no longer be drawn out by the drawing roller of the calender mechanism, but instead stagnates in the space between the guide surface and the feeding mechanism.

Therefore, as a practical spinning machine, it is naturally necessary to take measures against such cases. That is, there is a special device that detects if the web stagnates in the space between the guide surface and the feeding mechanism, displays this in some cases, stops feeding the web, and makes it possible to remove the stagnant web. is necessary.

As a result of various studies regarding this point, the following solution was found. That is, a support element for adjusting the position of the guide surface is provided between the rollers of the feeding mechanism, a switch element is interlocked with the guide surface, and the switch element is activated when the pressure of the stagnant web exceeds a certain value. The problem was solved by configuring the guide surface to be moved away from the roller. That is, in this particular device, the guide surface of the guide element is designed to be movable, that is to say rotatable, pivotable or movable.
When the web becomes lodged in the space between the feed mechanism and the guide surface, the pressure on the guide surface increases, for example by pivoting and pressing a limit switch. The limit switch activates an optical or acoustic indicator, so that the guide surface can be manually opened in response to this and the obstruction cleared. It is further advantageous if the limit switch activates an opening device which automatically moves the guide surface away from the rollers. It is also preferred that the limit switch is capable of activating a shut-off device that stops the supply of web from the card. In a particularly preferred embodiment, a limit switch is actuated when the guide surface leaves a limit position associated with the feed mechanism, so that the feed of the web is stopped at the same time as the guide surface release device is actuated. In this embodiment, when the web stagnates, the pressure actuates a limit switch to stop the web feed and at the same time open the guide surface so that the obstruction can be removed.

In order to make the guide surface rotatable or pivotable, it is preferable from a structural standpoint that the guide surface is provided with a hinge. An advantage of this embodiment is that when the web stagnates, the pressure not only displaces the guide surface, but also allows the guide surface to be opened so that the obstruction can be removed. In this embodiment, the web pressure can be adjusted, for example, by combining the hinge bearing with an adjustable spring load.

When the web pressure exceeds a certain value, a limit switch is activated. It is preferable to use a microswitch with a small reaction stroke as the limit switch.

In a preferred embodiment, the guide surface is attached to the holding arm, for example under the bias of a leaf spring. The limit switch may be mounted directly on the guide surface under spring bias. With this configuration, after the obstacle has been removed, the guide surface can be automatically returned toward the supply mechanism, for example, by a pivoting motion.

The configuration and effects of the device will be specifically described below with reference to the embodiments shown in the accompanying drawings (FIGS. 19 to 22).

In FIG. 19, downstream of the squeeze rollers 5, 6 of the feeding mechanism, a guide element constituted by two guide surface members 8u, 8u' is shown.
is located close to. These members 8u, 8
u' are held in one row in the horizontal direction via bushes 52 and holding arms 71, which are respectively supported rotatably around fixed pins around vertical axes.
A protrusion 6 is provided on the end surface of the holding arm 71 to operate a limit switch 68 fixed to the holder 51.
9 will be provided. It is preferable that the holding arm 71 be biased in the counterclockwise direction by a spring force. During operation, in the space formed between the members 8u, 8u' of the guide element and the rollers 5, 6, when the pressure acting on the members 8u, 8u' increases under normal conditions, the holding arm 71 rotates in the direction of the hour hand. The limit switch 68 is actuated via the protrusion 69, and as a result, the display device 49 is actuated. Next, by manually rotating the members 8u, 8u' further in the direction of the hour hand, the webs stagnant within the guide surface members 8u, 8u' can be removed.

In FIG. 20, the individual guide surface members 8v, 8v' are connected to the holding arm 71a via leaf springs 52, which hold the members 8v, 8v' at a distance from the holding arm 71a. . In this embodiment, the guide surface members 8v, 8v' can be pivoted. A limit switch 70a is provided on a holding arm 71a that cooperates with the guide surface member. This limit switch 70a consists of a leaf spring 52 and a holding arm 7.
1a and guide surface member 8v or 8 in cooperation with this
It is located between v′. Operating parts 8v or 8
When the pressure of the web acting on v' exceeds a certain value, the back surface of guide surface member 8v or 8v' presses limit switch 70a to operate it. The limit switch 70a is connected to the gear 5 via a conductor 53.
It acts on the motor 56 with 5. Said gear 55 meshes with a gear 54 mounted on a rotatable bush 52. As the bush 52 rotates, the corresponding guide surface member 8v or 8v' is automatically rotated in the direction of the hour hand via the holder 71a and the leaf spring 52 to the extent that the obstruction caused by the stagnation of the web can be removed.

In FIG. 21, a hinge 57 that is rotatable about a horizontal axis is provided on the guide surface member 8w.
A limit switch 70b that can engage with the back surface of the guide member 8w is provided on the fixed holder 58 on the side opposite to the squeeze rollers 5 and 6. When the pressure of the web exceeds a certain value, the guide surface member 8w
When the member rotates in the direction of the hour hand and the back side of the member acts on the limit switch 70b, the limit switch 70b is activated. The holder 58 is a connecting member 59
When the web is held in the bracket 60 via the
The bracket 60 can be moved horizontally on the rail 61 by the pneumatic action of the pressure cylinder D.

FIG. 22 shows an embodiment in which the guide element 8x has a guide part 62 which is horizontally movable in a guide 63 which is fixed on the side opposite the squeeze rollers 5, 6. A limit switch 70c operates inside the guide portion 62. A rod 65 is provided which is biased by a compression spring 64, and a limit switch 70c is installed on the fixed guide 63.
When the web stagnates, limit switch 70c
After actuation, the guide element 8x pivots downward about the fulcrum 66. The limit switch 70c controls, for example, the operation of an actuating section of a supply roller (not shown) of the card by means of a shutoff device 67, and by activating the shutoff device, the fiber supply to the card is cut off, and the web is removed from the roller of the supply mechanism. Stop supply. The second problem is that the guide element is used when changing the speed of a cylinder, carder, or other rotating body, such as when starting a carding machine or adjusting the operating speed for web splicing work. The problem is adjusting the position of the guide surface. This problem is solved in the present invention as described below.

As is well known, the operating speed of the web removal and take-off rollers of the carding machine is adjusted in stages. When performing web joining work, the cylinders are already set at full speed, and rollers such as the web take-out roller, take-off roller, stripper roller, squeeze roller, and calender roller are first set to the web joining speed. lower. When the web joining operation is completed, these rollers are increased to a high running speed and the guide surfaces of the integral or multi-component guide elements are manually returned to their normal working position. If a problem occurs in the formation of the web, the running speed of these rollers is reduced again to a low rotational speed, and the guide surface is manually pulled away from the squeeze roller surface to remove the problem.

However, such manual work is complicated, reduces work efficiency, and requires skill. Therefore, in the present invention, the problem has been solved by providing a web focusing and guiding device that can automatically adjust the position of the guiding surface of the guiding element.

That is, the problem was solved by providing an element for adjusting the position of the guide surface with respect to the roller of the web take-out and supply mechanism according to the rotational speed of at least one of these rollers.

According to the invention, in order to displace the guide surfaces of the one-piece or multi-component guide elements, for example the rotational speed of these rollers is varied. Varying the rotational speed of supply and retrieval rollers such as stripper rollers, squeeze rollers, take-up rollers, etc. By coordinating a position adjustment element controlled by the rotation speed of the roller with the guide surface, the guide surface is automatically moved away from or extremely close to the squeeze roller as the rotation speed changes. I can do it.

Preferably, as means for adjusting the position of the guide surfaces, there is provided a measured value generator actuated by at least one of the web removal and calender rollers, a control device connected thereto, and an adjustment member associated with each guide surface. Preferably, the guide surface or adjustment member is continuously movable. For example, a generator may be used as the measured value generator. A voltage-dependent relay is suitable as the target value setting device.

The structure, function and effect of the automatic device will be described in detail below with reference to the embodiments shown in the accompanying drawings (FIGS. 22 to 26).

In FIG. 22a, the taker-in roller 73 and the feed roller 72 are arranged in front of the cylinder 1 of the carding machine, and the carder 3, the stripper roller 4, the squeeze rollers 5, 6 and the calender are arranged behind the cylinder 1 with respect to the working direction. A roller 74 is arranged. Immediately behind the squeeze rollers 5, 6 there is provided a web collection device including a guide element 8, with which the hinge 52 and the adjustment member 76 are associated. The adjusting element 76 is connected via conductors 77, 78 to a control device 79, which is connected via further conductors to a measured value generator 80, for example a generator, which is installed on the feed roller 72. . The control device 79 is associated with a target value setting device 81, for example a voltage-dependent relay. The control device 79 can have both slow and fast action areas.

As is clear from FIG. 23, the feed roller 7
2. A generator as a measured value generator 80 and a relay as a target value setting device 81 are connected to each other, and the target value setting device 81 is connected to two conductors 82, 82.
For example, a so-called 4/2-stroke magnetic valve is connected via a.

The control device 79 is connected to the regulating element 76 via compressed air conduits 77 , 78 , the conduit 77 being connected to the regulating element 7
6 and one side 83b of the piston 83 in the conduit 7
8 acts on the other side 83a, respectively. The adjustment member 79 includes an electromagnetic coil 84 connected to conductive wires 82, 82a. A movable core 85 is placed within the coil 84 and held by a compression spring 85a. The other end of the iron core 85 is connected to the outlet of a passage 86, and the inlet of said passage is connected to a pressure chamber 87. A piston 88 is disposed in the pressure chamber 87 so as to be freely interlocked. Opposed to the entrance of the passage 86 is a compressed air supply source P, conduits 77, 78 and two discharge pipes 89, 90.
Connect. If the rotation speed of the feed roller 72 is low,
Since the voltage supplied by the measured value generator 80 is low, the relay used as the setpoint value setting device 81 does not respond. Iron core 85 closes the end of passage 86. The air coming out from the compressed air supply source P is transferred to the piston 8
8 and the wall of the pressure chamber 87 through the conduit 7
8 and acts on the surface 83a of the piston 83 in the adjustment member 76, causing a guide element (not shown) to be pulled away from the circumferential surface of the squeeze roller and released. Air is discharged from the surface 83b of the piston 83 through the conduit 77 and the discharge tube 90. When the rotational speed of the feed roller 72 is high, a high voltage is supplied by the measurement value generator 80, in response to which the relay supplies a pulse to the coil 84, and at the same time the iron core 85 is supplied with a high voltage.
is drawn into the coil 84, and the iron core 85 is drawn into the passage 86.
Open the end. Compressed air from the compressed air source P therefore flows through the passage 86 into the space above the piston 88 and presses it. As a result, since the conduit 77 is released, air pressure acts from the compressed air supply source P on the opposite side 83b of the piston 83 in the adjustment member 76, closing the guide element and squeezing the piston 83.
Take a working position very close to the circumferential surface of the roller.
Air is now released from the side 83a of the piston 83 through the conduit 78 and the discharge pipe 89.

FIG. 24 shows the squeeze rollers 5, 6 and the guide element with two guide surfaces 8y, 8y' arranged behind them. Only the holding and operation of the guide surface member 8y will be explained below. In addition, the guide surface member 8
Needless to say, the same holds true for y′.

As is clear from FIG. 24, the guide surface member 8y
A holding arm 48b is provided on the
The pin 50 is attached to the upper end of the pin 50 via a bushing 52.
It is supported so that it can rotate freely around its vertical axis. A U-shaped lever 91 is fixed to the lower end of the bush 52.
The rotation speed of the feed roller 72 is determined by the target value setting device 81.
, the controller 79 receives a signal and the pressure in the conduit 77 increases. As a result, the piston (second
(Fig. 3) moves, and the adjustment member 76 moves to the lever 91.
The cylinder rod 92 in interlocking relationship with the cylinder rod 92 is moved outward. The lever 91 and the holding arm 48b move in the direction of the hour hand to release the guide surface member 8y from the working position. That is, move it away from the rollers 5 and 6.
For example, when the number of revolutions of the feed roller 72 increases above a certain value, such as when starting a carding machine, the guide surface member 8y moves to the closed position as a result of the pressure from the control device 79 to the conduit 78 increasing. That is, rollers 5, 6
Once moved.

As shown in FIG. 25 (closed position) and FIG. 26 (open position), a holding arm 48c is attached to the guiding member 8z, the other end of which is attached to a cylinder of an adjusting member 76, such as a pneumatic device. It is attached to rod 92. Holding arm 48
One end of a relatively long link 93 is attached to the intermediate position between both ends of the cylinder c, and a relatively short link 94 is attached to the cylinder rod 92 together with the holding arm 48c. The other ends of links 93 and 94 connect to corresponding fixed hinges 95 and 96. When the cylinder rod 92 is retracted into the adjustment member 76,
The link systems 48c, 93, 94 are activated,
Guide surface member 8 to which holding arm 48c is attached
z pivots from the closed position shown in FIG. 25 to the open position shown in FIG. 26. The other guide surface member 8z' is also associated with a similar linkage system and adjustment member.

A third problem is that in carding machines of the basic configuration described above, the free air flow generally acts on the web running in a focused manner in the region between the guide element and the trumpet, resulting in damage to the web. There is a possibility that this could happen. This problem is particularly acute if the focused web is pulled out of the guide element at high speeds. However, this problem has been solved by making the distance between the trumpet and the guide element extremely small, even close to zero. This arrangement prevents the air flow from acting directly on the focused web, and since the trumpet is located in close proximity to the guide element, the web immediately passes from the guide element to the trumpet. From this point of view, the trumpet is preferably provided as an extension of the guide surface and fixed thereto. In this case, the trumpet can be formed separately and attached to the outlet of the guide element. However, it may also be formed integrally with the same material as the guide surface member, for example by deep drawing. It is preferable that the guide surface member, the trumpet and the calender roller are movable integrally with respect to the squeeze roller. With this configuration, it is possible to monitor the web fed from the squeeze roller during operation and to prevent obstructions. During removal, it is possible not only to move the integrated structure away from the squeeze roller, but also to facilitate the web splicing operation in which the web coming out of the squeeze roller is captured by hand and introduced into the trumpet. . It is also advantageous to construct the trumpet and calender roller so that they can be displaced relative to the guide element. With this arrangement, the trumpet and the calender roller can be displaced independently of each other with respect to the guide element. Displacement of the trumpet and calender rollers alone, or together with structurally integral guiding elements, can be accomplished by pivoting or tilting upwards or downwards about a horizontal axis.

The configuration and effects of the above-mentioned trumpet-equipped device will be explained in detail with reference to the embodiments disclosed in the accompanying drawings (FIGS. 27 to 30).

In the embodiment of FIG. 27, the web removal mechanism (located at the rear of the carding machine, not shown) comprises two rollers 5, 6, in close proximity to which a concave guide element 8 is installed. It is located. The opening 24 of the guide element 8 passes directly into the trumpet 7. Trumpet 7 has two calendars.
Rollers 74 and 75 are provided close to each other. The trumpet 7 and the calender rollers 74, 75 together with the guide elements form a so-called calender mechanism which is movable in the running direction of the web, that is, in the horizontal direction. Therefore, two holding members 92, 9
3, the calender mechanism and the guide element 8 are attached to a transport element 28 which is horizontally movable on a rail 29.

In the embodiment shown in FIG.
It is constructed so that it can pivot downward from the position shown in the figure.

In the embodiment of the guide element 8 shown in FIG. 29, a circular outlet 24 is provided intermediate the side edges 12, 13, the edges of which have rounded corners. A guide element 8 is placed immediately behind and in close proximity to the rollers 5, 6 (only roller 5 is shown) so that the focused web is not adversely affected by the airflow. The delivery side working surface (Fig. 27),
The running web is covered to protect it from the influence of outside air. The horizontal longitudinal edge (for example 21) of the guide element 8 is brought into close contact with the generatrix of the rollers 5,6. The guide surface 10 of the guide element 8 is formed in a slightly conical shape so as to guide the web smoothly into the trumpet 7. By bringing the side edges 12, 13 of the guide element 8 into close or almost close contact with the side end faces of the rollers 5, 6, all the web coming out of the rollers 5, 6 is captured by the guide element 8. The guide element 8 is connected via two holding parts 95, 96 to the holding member of the calender rollers 74, 75 (calendar roller 7
(only 4 is shown). A hinge element (eg 14a) is provided on the outer edge 12 and the guide element 8
, a trumpet 7 provided on the guide element 8, and calender rollers 74, 75 connected to the guide element 8.
and a second axis around the vertical axis via the hinge element.
9. It is configured to be able to turn from the position shown in FIG. 9 to a position away from the rollers 5 and 6.

FIG. 30 shows an embodiment in which the guide elements 8 are provided in close proximity to the rollers 5, 6. Behind the guide element 8 there is a trumpet 7 and a calender roller 74,
A calendar mechanism integrally constructed from 75 is disposed. The trumpet 7 is connected via a holder 97, and the calendar rollers 74, 75 are connected via a holder 93 to a moving element 28, which moves the calendar mechanism relative to and independently of the guiding element 8. This enables horizontal movement along 29.

The next problem is how to quickly increase the functionality of the aforementioned guide elements when starting up a carding machine that has been stopped. Generally, at the end of each day's work, textile processing machines are shut down and cooled down until the next start of work. When operation begins in the morning, the temperature of the machine gradually increases due to frictional heat and an increase in indoor temperature, but by the time the machine reaches a certain working temperature, the fibers may wind around the rollers or become tangled with the parts they come into contact with. many. In the device according to the present invention, it is still desirable to address this problem in order to obtain more effective effects.

In practice, it generally takes a long time for the mechanical parts of the carding machine to reach a high and uniform working temperature.
Experience shows that in cold machine conditions, web capture cannot be carried out quickly and reliably, with the inconvenience of having to wait until the machine temperature reaches a certain temperature.

As a result of various studies, a web collecting and guiding means was developed that can quickly and reliably capture the web within a very short time after the carding machine is started. This point will be explained in more detail below.

Experience has shown that the operating temperature of the carding machine rollers and web guiding device is at a certain level, e.g. 20-30°C.
Only after reaching this point can the web be captured quickly and reliably. This seems to be related to the fact that the temperature at the beginning of the engine prevents the web from sliding against the guide surface. If the guide surface of the web guide device can be heated freely, the time required to reach a predetermined working temperature can be significantly shortened. In order to provide such a function to the guide surface, it is preferable to provide an electric heating device on the opposite side of the guide surface from the web, and at least a portion of the guide surface may be covered by the heating element of the electric heating device. desirable. In a preferred embodiment, the electric heating device is adjustable. The temperature can be adjusted continuously or by a selection switch from approximately 20°C to 80°C. The advantage of higher temperatures is that the running speed of the web can be increased, thus increasing production capacity. That is, it is believed that higher temperatures significantly increase the slippage of the fibers relative to the web guiding device. It is also believed that the web guiding device beneficially affects the airflow in this space by warming the air between the guiding surface and the squeeze roller.

The attached drawing (Part 3) shows the heating means described above.
With reference to the embodiment shown in FIGS. 1 and 32), the configuration, operation and effect will be explained in detail.

In the embodiment shown in FIG. 31, a holding member 33 is provided behind the two squeeze rollers 5, 6,
The holding member is attached to the side frame of the carding machine via attachment members (not shown). The holding member 33 has a prismatic cross-sectional shape. A guide element 8 is provided in the inner space of the holding member 33, which opens toward the rollers 5 and 6 and has a flat arcuate surface. On the side of the guide surface 10 opposite the squeeze rollers 5, 6 there is a heating element 98, for example a heater coil.
will be established. The heater coil is connected to a power source 100 via a conductor 99. This circuit is switch 1
01, and a regulating device 10, for example a rheostat.
It also includes 2. The heating element 98 is attached to the back side of the guide surface 10 via two insulator tubes 103 made of, for example, electroceramic. The insulator tube 103 serves both as an insulator and a spacer.

As shown in FIG. 32, a bimetal element 104 is arranged approximately in the center of the guide element 8 and behind the heating element 98, and a contact 105 is connected to this. Bimetal element 104 and contact 105 are connected in series with heating element 98 and power supply 100 to constitute a temperature control device. When a certain temperature is exceeded, the two components of bimetal element 104 made of different metals exhibit different expansions, resulting in bimetal element 104 curving away from contact 105 and interrupting the current flow.

It is also possible to configure the temperature control device consisting of the bimetallic element 104 and the contacts 105 to be linked to a control device (not shown) so that, for example, when a target temperature is reached, the guide element 8 is actuated by means of an adjustment member. .
