Description
Technical Field
The invention relates to a can pushing device, a can changer equipped therewith and a textile machine.
Background
In the can changer, the can pushing device is especially used as a component of the textile machine for removing the full can from the filling position and simultaneously moving the empty can into the filling position based on the can changer. In the filling position, the can changer deposits the fiber strand into the can located there in a known manner until the can is filled.
Various mechanical devices are known for moving the can. There are rotary can changers which move cans along a semicircle. In this case, a plurality of can pushers project free of attachment. The lack of adherence of the can pusher results in particular in a limitation of the size of the filled can. Furthermore, a plurality of can pushers is necessary, which complicates the construction.
There are also can changers that move cans along a straight path of movement. For this purpose, a plurality of can pushers are provided, each of which moves an associated can.
In order to be able to move large cans as well, the can changer is driven at both ends, which again complicates the construction.
Each can optionally be equipped with two can pushers which flank the respective can and move it. On return, the can pusher is deflected past the next can and springs back immediately when the latter is passed. Here too, a plurality of can pushers is urgently required, which in turn leads to a complex construction.
Disclosure of Invention
The object of the invention is to remedy the aforementioned disadvantages.
This object is solved by the subject matter of the independent claims. Advantageous variants are given in the dependent claims.
According to the invention, a can pushing device with a can pusher is provided. The can pusher is guided by one end along a predetermined path of movement. The device further comprises a drive mechanism comprising a drive section. The drive section is in moving operative connection with the one end of the can pusher. This means that a movement of the drive section translates into a corresponding movement of the can pusher. The drive mechanism is designed to move the drive section so as to move the can pusher along the path of movement through the aforementioned one end. In other words, the can pushing device according to the invention requires only one single can pusher, instead of a plurality of can pushers as in the prior art. This greatly simplifies the construction. Furthermore, the can pusher can be constructed without attachment as in a rotary can changer, which in turn further simplifies the construction.
The drive mechanism may be arranged for moving the drive section back and forth between the two end positions. In other words, unlike the rotary can changer, the can pusher used there can now also be used in a can changer for moving cans along a straight path of movement.
In the last-mentioned case, the drive mechanism is preferably constructed by means of a pneumatic cylinder. The aforementioned drive section is formed by the free end of the piston of the cylinder. This creates the known possibility that, although the end is free, it is possible to move a can with only one can pusher.
The drive section is connected to the one end of the can pusher, preferably in such a way that the aforementioned movable operative connection between the drive mechanism and the can pusher is formed. In other words, a simple fixing of the can pusher end is sufficient, which keeps the construction simple.
Each of the aforementioned devices furthermore preferably has a guide section extending along the movement path. The can pusher preferably has a mating guide section at the one end. The mating guide section is in turn preferably in a form-locking manner with the guide section, so that the mating guide section can be moved along the path of movement. In other words, the can pusher is moved by one and the same end and guided along the movement path. This enables the can pusher to be constructed without attachment in relation to the other end.
Each of the aforementioned can pushers preferably has a first support section at its end, which is designed to keep the other part of the can pusher at a distance from the at least one depending first counter-element on said one end along the path of movement. The counter element is for example a bottom, over which the can pusher moves. The bearing section enables decoupling of the mechanical device and enables a free end of the can pusher. It has surprisingly been shown that such a construction is capable of moving also large, full cans with a diameter of 1000mm and with a larger diameter. Also, an empty can that is pressed towards a full can does not suffer from a deformation that is so great that the can is no longer suitable for filling.
When a mating guide section is present, it is preferably precisely by means of this mating guide section that the first support section is constructed. In other words, the guide portion assumes a dual function, which further simplifies the construction.
Each of the aforementioned can pushers preferably has a second bearing section at its other end, which is designed to keep the other part of the can pusher at a distance from at least one associated second counter element at said other end. The counter element may still be a bottom. Alternatively or additionally, the counter element can likewise be, for example, a face of the can changer facing the free end of the can pusher. When a first support section is present, this relieves the first support section of load or renders it superfluous.
When present, at least one of the support sections preferably comprises at least one roller. The rolling surface of the roller is configured to roll on the associated counter-element. The at least one bearing section can alternatively or additionally be positively engaged with an associated counter-element. In the case of rollers, the engagement can be achieved by means of a convex spherical rolling surface and a recess, arcuate in cross section, as a sliding rail. A slider-slot guide may be provided. Known linear guides, such as dovetail guides, can also optionally be used. It offers a number of possibilities.
Each of the aforementioned can pushers may have a positioning section. The positioning sections are designed to counteract in opposition the movement of the (empty) can pressed in the predetermined direction and in contact with the can pusher towards one or both ends of the can pusher when the can pusher is moved in the predetermined direction along said path of movement. In other words, the lateral movement of the empty can in at least one direction is hampered. According to the invention, this effect is enhanced when an empty can is pressed towards a full can. This improves the safety and stability of operation. Furthermore, expensive side guides for the can be omitted, which makes the construction simple.
The positioning section preferably has an inward bend which is directed in the predetermined direction. This enables the squeezed can to be guided sideways according to the aforementioned convex spherical rolling surface, when the circular periphery of the circular can is considered as a rolling surface. Alternatively, the inner curvature is configured complementarily to the corresponding outer contour of the can to be moved. When the can is rectangular, the inturned portion is, for example, substantially rectangular (which is substantially because the corners of a rectangular can are actually rounded). This solution can thus be universally applicable.
As is known, the can changer according to the invention is designed such that the incoming fibre sliver is deposited in the spinning can according to a predetermined pattern in the filling position. The can changer furthermore has one of the aforementioned devices. The device is arranged to move the empty can in a predetermined direction towards its filling position when the can pusher is moved. The filling position is located in a known manner below the rotating disc of the can coiler.
The can changer is preferably designed such that, as soon as a can is in the filling position, a full can is simultaneously removed from the filling position by means of the can pusher when an empty can is moved into the filling position. In other words, a single can pusher is sufficient to replace the can(s).
Here, the empty can is pressed against the full can by means of the can pusher, preferably by this movement of the full can.
The textile machine according to the invention has one of the aforementioned can changers, or is connected to such a can changer. The first-mentioned cases exemplarily include a drawing frame, a combing machine, and a roving frame. The second mentioned case relates exemplarily to a carding machine with a can winding device arranged downstream. "connected" is therefore a functional expression and means connected in relation to the sliver production process or in relation to the yarn production process.
The method according to the invention for driving any of the aforementioned can changers or for driving a can changer of the aforementioned textile machine comprises a cycle. The cycle comprises a first step, carried out when the can pusher is located outside an initial position from which it comes out, able to bring an empty can to a filling position based on the driving mechanism in the aforementioned movement along the movement path. The first step consists in moving the can pusher into said initial position. This ensures that the can pusher is in the correct position for can replacement. The cycle comprises a second step carried out when a predetermined starting position of the can changer is free. In the starting position, the can changer in the initial position can bring an empty can into the filling position on the basis of the drive mechanism in the aforementioned movement along the movement path. The second step comprises moving the empty can into the starting position. The cycle furthermore comprises a third step which is carried out when the filling position is empty or a full can is in the filling position. The concept of "full cans" means that the associated can is filled "full" as the case may be. When a filled can, for example, just needs to contain the remaining part of the previously produced fiber strand before a partial replacement, the can does not need to be filled for the replacement, which is the meaning to be expressed by the present invention. In a third step, the can pusher is moved outward from the starting position, so that the can pusher brings the can located in the starting position into the filling position, so that a full can is pushed out of the filling position as long as there is an empty can. This results in a simpler can changing process, which can also be carried out very quickly. Depending on the implementation of the can changer, the first and second steps can be carried out independently of one another in terms of time or can be carried out one after the other in terms of time.
The method according to the invention furthermore preferably comprises a fourth step of filling the can at the filling position with fibrous material.
In each of the aforementioned methods, the cycle is preferably repeated, resulting in a continuous fiber material stacking process and can changing process.
Drawings
Additional features and advantages of the present invention are set forth in the description of the preferred embodiments that follows. In the figure:
figure 1 shows a device with a carding machine and a can changer arranged downstream,
figure 2 shows a top view of the part of the can changer below the can winding device,
fig. 3 shows a partial view of the can changer of fig. 1.
Detailed description of the preferred embodiments
Fig. 1 shows a device 1 with a carding machine 2, a can coiler 3 arranged downstream and a can changer 100 attached thereto.
The carding machine 2 and the can winding device 3 are arranged on a chassis 4, in which a drive for a non-visible can turn disc of the can winding device 3 is arranged, for example. The example shown relates to a so-called underground installation, in which the chassis 4 is constructed with its upper side flush with the ground surrounding it. It can optionally be mounted in a so-called open-faced manner, wherein a loading and unloading platform is additionally provided on the front side in order to be able to push the empty can 5a shown here onto a stop surface 101, shown here on the left side, of the can changer 100. The carding machine 2 and the can coiler 3 arranged downstream are constructed in a conventional manner and will not be described further.
A guide roller 102 is located in a stationary manner on the left side of the stop surface 101, and the axis of rotation of the guide roller 102 extends perpendicular to the ground or perpendicular to the upper side of the chassis 4. The guide roller 102 serves to prevent the empty can 5a, which is preferably moved manually onto the stop surface 101, from being moved further to the left, i.e. away from the can winding device 3. This makes it possible to safely and reliably push the empty can 5a onto the stop surface 101.
A can pusher 121 of a can pushing device 120, described further below, is located to the left of the rest surface 101. The rear side of the stop surface 101 facing the carding machine 2 abuts on the drive section 110 of the can changer 100.
The can changer 100 with the can winding device 3 operates as follows: no can is initially located below the can winding device 3. The first empty can 5a is pushed onto said resting surface 101. The can pusher 121 is then moved by means of the drive section 110 in the direction of the can winding device 3, so that the empty can 5a comes under the can winding device 3. The empty can 5a is brought into rotation and is filled with the fibre sliver 6 by means of the can winding device 3. This empty can 5a thus becomes a can 5b to be filled. When the can 5b is full, it becomes a full can 5 c. During which a new empty can 5a is pushed onto said resting surface 101. In order to now replace the full can 5c with a new empty can 5a, the drive section 110 presses the can pusher 121 toward the empty can 5a on the stop surface 101 in the direction of the winding device 3, wherein the empty can 5a is pressed toward the full can 5 c. In other words, the can pusher 121 pushes the just filled full can 5c out of the can winding device 3 through the empty can 5 a. As shown in fig. 1, the full can 5c comes to the right of the can winding device 3. The drive section 110 then returns the can pusher 121 again to the initial position shown in fig. 1.
Fig. 2 shows a top view of the part of the can changer 100 below the can winding device 3. In other words, the view to here two cans 5a, 5c is open. The can changer 100 is shown in a state in which the empty can 5a that has just been pushed is located on the stop surface 101.
The full can 5c filled with the fiber strand 6 is currently located on a stop section 8, which defines the filling position for the respectively arranged cans 5a, 5 b. As can be seen, the guide roller 102 is at a distance from the can pusher 121. The can pusher 121 of the can pushing device 120 is here constructed by means of a rod-shaped component. Here, the can pusher 121 extends substantially transversely to the path of movement of the empty can 5a from the stop surface 101 to the stop section 8. The can pusher 121 is provided at its lower free end with a roller 128, the axis of rotation of which extends transversely to the plane of the resting surface 101 and transversely to the path of movement. The circumferential rolling surface of the roller 128 bears against the stop surface 101, so that the roller 128 rolls on the stop surface 101 when the can pusher 121 is moved. The roller 128 serves to maintain the drum pusher 121 at its lower free end at a distance from the stop surface 101. The can pusher 121 has a centering section 122 approximately in the center, which is fastened to the can pusher 121, for example by means of two screws 11. The centering section 122 serves to bring the empty can into position when the can pusher 121 is moved toward the empty can 5a, so that its vertical position in fig. two corresponds to the vertical position of the full can 5 c. For this purpose, the centering section 122 preferably has an inward curve or recess, not shown here, in the direction of the resting section 8.
The can pusher 121 is fastened at its upper end to the connecting element 123 or is formed integrally therewith. Preferably by means of the connecting element 123, the drive section 110 is able to move the can pusher 121 along its path of movement. The drive section 110 is here covered by a cover 111. On the right side of the covering section 111 there is a further covering section 14, below which a guide section or guide rail 140 is partially arranged visible.
Furthermore, a drive motor 9 is shown, which rotates a can rotor disk, not visible here, for the full can 5c shown here, by means of which the can winding device 3 can deposit the sliver 6 in the can 5c in a cycloidal manner by means of its can winding device. The fixing element is responsible for keeping the can 5c in its position in a known manner.
Fig. 3 shows a partial view of the can changer 100. Only the main parts of the can changer 100 are shown here.
In fig. 3a, a bottom element 13 is shown, which has a through opening 13a for the can turn disc. The bottom element 13 preferably extends through the region of the stop section 8 and the region of the stop surface 101.
The cover 14 has been removed so that the view to the guide rail 140 is open. The guide rail 140 has a roller section 141 pointing upwards and serves to guide the can pusher 121 along the path of movement. The central section 122 with the inward curve is clearly visible. According to the embodiment shown here, the can pusher 121 is mounted on the connecting element 123 by means of three bolts 11. Of course any other form of attachment may be used, such as clamping, welding and the like.
The drive section 110 has, in addition to the cover 111 which points upwards, a cover 113 which points in the direction of the can pusher 121. The cover 111 is formed by means of a flanged profile, for example, so that an interior space is formed in connection with the cover 113, in which interior space the pneumatic cylinder 112 of the drive section 110 is arranged. The pneumatic cylinder 112 is arranged such that its piston 112a projects to the right here. The piston 112a is connected to an actuator 125, which is connected to the connecting element 123 via a connecting element 124.
Thereby, it is possible for the pneumatic cylinder 112 to move the can pusher 121 along its path of movement to the right in the direction of the through opening 13a by moving out the piston 112 a.
Fig. 3b shows the left-hand end of the device in fig. 3a in a perspective view.
Said can pusher 121 with a centring section 122 and a connecting element 123 are shown implicitly. The pneumatic cylinder 112 is preferably fastened to the cover 111 at its end facing the can pusher 121 by means of four screws 11. As can be seen, the can pusher 121 is fixed to the connecting element 123 by means of the bolt-and- nut fastening 11, 12.
The guide section 126 is mounted on the side facing away from the pneumatic cylinder 112 and facing the chassis 13. The guide portion 126 is accommodated guided along the displacement path on the guide rail 140.
Fig. 3c and 3d primarily show the fixing of the pneumatic cylinder 112 and its connection to the actuator 125.
The actuator 125 is fixed to the connecting element 124 or is formed integrally therewith.
The piston 112a of the pneumatic cylinder 112 opens at its free end 112b into a sleeve-like receptacle into which the round rod 127 is pushed through. The round bar 127 is received at both ends in a freely rotatable or positionally fixed manner by the free legs of the here u-shaped co-actuator 125. A thin-plate-shaped bearing section 131 is mounted on the front side wall of the co-actuator 125 here by means of two screws 11, the upper edge of which engages in a groove-like recess of the closure element 129, so that the right end of the rod 127 here is closed. Thereby, the co-actuator 125 is locked in its position in a direction transverse to the movement path and parallel to the surface of the chassis 13 not visible here. The round bar 127 makes it possible to offset the unevenness of the bottom surface when the barrel pusher 121 moves.
As can be seen in fig. 3d, the holding bracket 115 is mounted on the vertical inner wall of the covering part 111 on the covering part 111, and on the free end of the holding bracket the pneumatic cylinder 112 is mounted here on the half of the holding bracket by means of two screws 11. On the other half on the left, the pneumatic cylinder 112 is fastened, for example, in a similar manner to a cover 113, which is not shown here. The fixing of the holding bracket 115 is effected by way of example by means of two screws 11 and associated nuts 12, wherein only the upper screw 11 is visible.
Fig. 3e shows the can pushing device 120 in a partially exploded view.
As already explained above, the connecting element 123 at its end facing away from the can pusher 121 is screwed together with the connecting element 124 here by three screws 11. For this purpose, the connecting element 123 has three passage openings 123a at corresponding locations, through which the associated screw 11 is screwed into the corresponding fastening opening 124a of the connecting element 124 or screwed in a lead-through manner with the associated nut 12.
The actuator furthermore has a U-shaped recess 123b between the two through openings 123 a. In the region of this recess 123b, two further bolts 11 are guided through non-visible through openings in the connecting element 124 and screwed together with the guide section 126. The second guide section 126 is located in the region of the rear end of the connecting element 124. The two guide sections 126 are identically constructed. They have a body which is configured as a guide sleeve 126 a. The guide sleeve 126a has a recess 126c extending in the direction of the displacement path, which recess is partially open in the example shown. The slide facing surface 126b is placed in the recess 126 c.
The other connecting element 114 is arranged in a stationary manner on the upper side of the connecting element 124 or is formed integrally with the connecting element 124.
The guide rail 140 has a fastening section 142, which with a support surface 143 pointing downward here rests, for example, on the chassis 13. The fastening of the guide rail 140 is again carried out by way of example by means of a bolt 11. In the upper right region, the guide rail 141 has a roller surface section 141 which is circular in cross section and is designed in such a way that the guide section 126 can be pushed along the displacement path with its sliding surface 126b in a form-fitting manner.
By means of the two screws 11, the stop element 130 is fixed on the here forwardly directed, vertical outer side of the connecting element 114 in such a way that the lower end of the stop element 130 projects beyond the connecting element 124, so that a projection is produced.
This type of projection enables the can pusher 121 to deflect in some way around the longitudinal extension of the guide rail 140. This can counteract unevenness of the bottom surface, for example. In order that the can pusher 121 is not lifted in an unreliable manner, the stop element 130 is provided. In fig. 3e, when the upward pivoting angle of the can bar pusher 121 about the roller section 141 is at its maximum, the stop element 130 abuts against a stationary part of the can changer 100 and thereby limits the pivoting of the can bar pusher 121. This fixed position is preferably formed by means of the fixing section 142 of the guide rail 140.
The present invention is not limited to the foregoing embodiments.
Instead of the pneumatic cylinder 112, other drive mechanisms can also be used, such as an electric motor in the form of, for example, a linear motor. The guide rail 140 may comprise a coil assembly or be electrically excited by a coil assembly, for example, and the guide section 126 may be designed as a rotor of the motor, for example.
Instead of moving back and forth, provision can also be made for the can pusher 121 to move in only one direction. For example, an annular channel can be envisaged along which the can pusher is moved.
The connection between the drive section 110 and the can pusher 121 can be designed differently. For example, the pneumatic cylinder can be pushed to the left in fig. 1, so that the connecting element 124 becomes superfluous. The connection of the end 112b to the rod 127 can likewise be replaced, for example, by a rigid fastening.
Instead of a positive connection between the guide section 126 and the guide rail 140, any other form of guide can likewise be provided. For example, the guide section 126 can have guide rollers which, for example, run on the outside of the rail section 141.
The roller 128 can be replaced, for example, by a slide which is accommodated in a guide groove formed in the chassis 13 in a guided manner. The guide groove extends here along the path of movement of the can pusher 121.
The can pusher 121 has a bend similar to a rotary can changer, whereby the midsection section 122 can be replaced.
The invention can be applied to any textile machine with a can device (integrated or downstream connected). The textile machines are here, for example, drawing frames, combing machines and roving frames.
The roller 128 does not necessarily have to be formed at the free end of the can pusher 121. The roller 128 or any other guide section can be mounted, for example, on the side of the can pusher 121 facing the base element 13 or can be formed integrally therewith.
The invention finally provides the possibility of realizing a can changer for particularly large cans at low cost and with a simple construction.
