Description

FIELD OF THE INVENTION

The invention relates to automatic technological equipment for the continuous winding of bays of long materials, in particular cable. It can be used at manufacturers of long products to form packages during the manufacturing process, as well as at consumer enterprises for rewinding long materials (cable, wire, etc.) from large drums to frameless bays convenient for work.

State of the art

For manufacturers of cables (or wires), one of the main tasks is to ensure a constant cable pulling speed and continuity of the winding process. This is due to the fact that in the manufacture of the cable its insulating layer is formed when pulling metal wires through the extruder. If the broaching speed is uneven, the applied insulating layer will be uneven: with increasing speed, the coating thickness will decrease, and when it slows down, sagging and thickening will form. The manufactured cable is immediately wound on a drum, the drive of which provides a certain winding speed. When one drum is full, you need to continue winding on the next. This will take some time to replace the drum or throw the cable to an empty one. To ensure the continuity of the process, the transition time of the process should be minimal or an additional storage device should be provided that can take a few meters of cable onto itself until the drums are replaced.

It is also important for enterprises-consumers of cable products to ensure the continuity of the winding process, especially in cases where it is necessary to rewind the cable into many small bays from one large drum. The problem is that at high winding speeds during the transient process (to cut the material, to organize a new winding), extra tens of meters of cable can run in, and the design of the bobbin winders should receive these extra meters or should minimize the length of the incoming wire. In other words, the design should prevent breakage or entanglement of the wound material.

From the Internet, research and patent literature, various designs of coils are known.

For example, the MOTROL 800 coiler is known, a manufacturer of technological equipment from Kabelmat, Germany (www.kabelmat.de). Its main characteristics: diameter of a bay or a drum max 800 mm; bay width max 250 mm; the diameter of the wound cable is 1-40 mm. Known BN-600 coils, which is designed to rewind cores, wires and cables into a bay, a coil with simultaneous visual control, equipment manufacturer LLC VNIIKP-Mash. Its characteristics of the cove heads are as follows: outer diameter 500, 600 mm; the diameter of the tummy is 150, 200 mm. These coils are intermittent-cycle devices, i.e. after winding a bay with the desired wire length, the rotation of the winding shaft is stopped and the cable is trimmed and the bay is removed from the winding place.

Of automatic devices, a large-sized twin-shaft winding machine, brand SN-10Sh2-1500, manufactured by JSC "Production of winding equipment" (website www.namotka.ru), which is designed to receive corrugated tubes from an extruder in production, is known. Two shafts allow for a continuous cycle: on one shaft, the corrugated pipe is received and the bay is formed, on the other at the same time, the finished bay is packaged and removed from the machine. Main parameters: diameter of the wound corrugated pipe (hose) - up to 100 mm; the maximum diameter of the frame is up to 1500 mm. The disadvantages of this device are the large amount of manual labor, the presence of a frame for wound bays and the need for a special device to remove these bays from the frames.

From the brochure of the Taiwanese company YA SIH TECHNOLOGI CO., LTD, the Hich speed double twist pairing machine, a high-speed winding machine, is known which provides the winding of two bays alternately on parallel frames, rotating from an electric drive and capable of folding to ensure unimpeded removal of the wound bay. The above-mentioned problem - control of incident cable meters during transients - is solved here using a separate device - a vertical drive, which manages to save several meters of cable in the form of winding into two coaxial and vertically spaced coils in one transient process of removing the finished bay.

As an analogue, consider a machine for continuous winding on a coil of predominantly metal wire (US patent No. 3980244). This machine contains a supporting and pulling device for two coils with parallel axes, gripping and guiding wires for single-row distribution during winding, as well as a lever that transfers the winded wire from the finished coil to a new one without interrupting the winding process with the same length without appearing effort creating a break. This machine contains: coil mounts; means for rotating coils; means for capturing the thread; means for guiding the thread for a uniform (turn to turn) winding, as well as a first swing arm carrying a guiding means and moving in two extreme positions at the end of winding of each coil; a second rocker arm synchronized in motion with the first and equipped with a passive pulley for receiving the wire before it reaches the wire direction pulley; a locator body, the vertical end of which is located between two coils and oscillates between two extreme positions along an axis parallel to the axis of the coils, the vertical end being located at a level that allows the wire to break when moving from one extreme position to another; means for moving the locator body to a position where the vertical end will push the intercepted wire to the gripping means of the empty coil; a vertical rod located at the same level as the end of the locator body. Moreover, this rod moves between two extreme points and it supports the length of the wire between the finished coil and the rod outside the area of the wire cut.

This device is not intended for winding frameless bays.

A disadvantage of this device is the complex lever design, which allows the wire to be thrown from one coil to another, as well as high requirements for the accuracy of synchronization of the moment of cutting the wire and the moment of completion of winding of each of the coils.

Known invention, the most suitable as a prototype. This is a dual winding machine with automatic transmission (US patent No. 4030673).

This winding machine contains a bed having supports for two pairs of spindles whose axes are parallel to the base and spaced vertically: one axis is located above the other at a certain distance. On each axis there are a pair of spindles, that is, there are driven spindles: upper and lower, and driving spindles: upper and lower. The spindles are mounted on a bed, and coils with the possibility of free rotation are put on their conical ends. The motor and drive are also fixed to the bed, which drives the driving spindles. Moreover, the leading spindles have a disk-shaped gearing, which serves to connect with the flanges of the coils (to transmit rotation to them). A spreader mechanism is located above the spindle axes, which serves to guide the wire during winding. Each coil has a special cutout for meshing the wire at the start of winding. To transfer the winding from one coil to another, there is a special deflecting device that causes a change in the path of the wire relative to the filled coil before it is fixed in the recess of the coil, and there is also a control system for the mechanism of deflection and repulsion of the wire.

The operation of the winding machine is as follows. Disc-shaped gears are connected to the coils. The engagement mechanism guides the wire into the cut of the upper coil to fix the beginning of the winding. The motor is turned on, the coils begin to rotate in the opposite direction and winding begins on the upper coil. When the upper coil is full, the deflector directs the wire to the lower coil to secure the wire in the section of the lower coil, after which the wire is cut and winding on the lower coil begins. After that, a disk-shaped gear is removed from the upper coil, the wound upper coil is removed and a new, empty one is put on. After winding the lower coil, the cycle repeats. The continuity of the process of this machine is ensured by high accuracy of synchronization of the processes of threading the wire into a special fixing cut at the beginning of winding and the moment of cutting the wire between the coils. The slightest violation in the control system of these processes can lead to tangling of the wire, that is, to disruption of the winding process. In addition, automatic removal of the wound spool is not provided here. The disadvantages are the mandatory use of permanent frame coils, that is, you can not reel frameless bay.

The proposed technical solution of the automatic bobbin winder is aimed at ensuring continuous winding (rewinding), and at a constant speed, of lengthy materials into bays, as well as removing high requirements for synchronizing the moment of throwing (from a filled frame to an empty one) with the moment of cutting of the wound material, to minimize "Run-in" of excess material during the transition process, to reduce external mechanical stresses on the formed bay when removed from the frame and when displaced Amotka and to ensure favorable conditions for further technological operations: packaging and transportation.

Disclosure of invention

Automatic Bucket contains:

- a bed on which the whole construction of the coiler is mounted;

- two drums, which are the frame for winding on them long material;

- spindles transmitting torque to the drums and their motors;

- two movable platforms, designed to ensure vertical movement of the drums along the guides, and actuators, providing them with linear movement;

- a distributor (that is, a feed device and a layout on the neck of the drum of a lengthy material) and a linear movement mechanism of its moving part;

- unsupported unit, structurally providing automation of the continuous winding process;

- a mechanism for cutting off a coiled bay;

- a manipulator, which is a mechanism for displacing finished bays from the place of winding;

- two countertops designed to receive finished bays from the manipulator;

- an elevator device designed to transport finished bays from one countertop to another.

The essence of the invention lies in the fact that two winding drums are located one above the other on the same vertical axis, with each drum having a body and a neck. The neck of each drum is made in the form of a circular cylinder, vertically cut into sectors that are mounted on the body with the possibility of moving away from it by a certain distance under radial mechanical action from the inside, thereby increasing the size of the neck.

The drums are mounted on the spindles, each of which is rigidly connected to the shaft of its rotation motor, and the drums can be moved vertically (upper - up, lower - down) thanks to movable platforms with guides rigidly mounted on the bed together with actuators, leading them back translational motion.

Each spindle is made of two main parts: a face plate and an axial pusher. The axial pusher is connected to the shaft of the rotation motor and in the middle part of its body has a smooth transition from a smaller diameter to a larger one. The faceplate is connected to the drum body using spring-loaded fingers having an internal vertical stroke in the body of the body with the corresponding mechanical action on the spindle (without the movement of the drum as a whole).

Between the drums on the same axis is placed an unsupported unit made in the form of a sleeve, on the edges of which flat round cheeks are planted with the possibility of free rotation on this sleeve. The cheeks play the role of the inner flanges of the drums, as they are in constant engagement with the ends of both drums or at least one of them. The ends of the necks of the drums facing each other have protrusions of a cylindrical shape with a circular groove at the base, the depth of which corresponds to the magnitude of the change in the radial size of the neck — the “stroke of the neck”. Each cheek of the supportless node has a flat shape with curly slots and a round hole in the middle, corresponding to the shape and size of the protrusion of the end face of the neck of the drum. The end face of the supportless node has such a surface configuration that corresponds to the design of the end face of the drum, and this ensures that the axle pusher moves from the periphery to the center (due to mutual mechanical impact) connecting the drum with the support node, namely, the fixed fixing of the cheek of the supportless node in the groove of the neck protrusion drum. And, conversely, with the reverse movement of the axial pusher from the center to the periphery, the unsupported assembly detaches from the drum.

Inside the drum body there are through horizontal holes in which spring-loaded radial pushers are placed, having mechanical contact with the outer surface of the axial pusher and the inner surface of the cylindrical sectors of the neck. The axial pusher itself in the middle part of its body has a smooth transition from a smaller diameter to a larger one. Therefore, with a vertical reciprocating motion of the axial pusher, mechanical action is provided on the spring-loaded radial pushers, which have a bursting effect on the cut neck of the drum.

In fact, the axial pusher performs two functions:

provides connection (or separation) of the cheeks of the supportless node with the ends of the drums;

changes the radial size of the neck within the "neck stroke".

The spatial arrangement of the supportless node is constant, and the drums can move vertically (upper - up, lower - down) on moving platforms with guides rigidly fixed to the frame. Moreover, most of the time both drums are connected to a support node. And only at the moment of displacement of the finished bay from the place of winding, its drum (that is, its winding frame) is disconnected from the cheek of the supportless node.

Winding is performed on the drums alternately. Moreover, during winding, the size of the neck of the drum is maximum - the sectors are as far away as possible from the drum body. After winding, the axial pusher moves to its initial position and the sectors are again connected to the housing due to the return springs - the neck size decreases. This ensures unhindered removal of the coil from the core of the coiled bay.

Winding on a reel and transferring winding from one reel to another is carried out with the help of a handler (a feeder and layout of the wound material), which is mounted on the frame and is oriented vertically along the zone between the extreme positions of the outer flanges of the drums. The figured shape of the cheeks of the supportless node in the form of petals tilted to one side provides a reliable grip of the wound material when transferring the winding from one coil to another.

When transferring the winding, for example, from the upper drum to the lower one, both drums rotate in the same direction at the same angular speed. After filling two rows of windings on the lower drum, the wound material is cut, then the rotation is forcibly (due to braking), and the upper drum is disconnected from the upper cheek of the supportless assembly. The coiled bay remains motionless to lie on this upper cheek, which has stopped rotation due to its loose fit on the sleeve of the unsupported assembly. The distance between the cheeks is small (a few centimeters), and it determines the length of the section of wound material to be cut.

The cut-off mechanism is attached to the bed, just at the level of the section to be cut, that is, the “cutting zone”. This mechanism has the ability to move horizontally, and according to the signal at the right time, its cutting part moves to the cutting zone and switches to the slow feed mode, which allows the cable to be cut in a time corresponding to several revolutions of the drum. That is, the segment is carried out without stopping the winding process.

Two worktops are horizontally fixed on the frame one above the other at the levels of the lower position of the necks of the upper and lower drums, and a manipulator is fixed at a level that provides unhindered movement from the place of winding of finished bays to these worktops. The manipulator moves the finished bays for further transportation and packaging.

The coil winder may include an elevator device located between two countertops for transporting finished bays from one to another and then sending it to the conveyor.

Thus, the proposed technical solution of the automatic loader provides the following technical result.

1. Provides a constant winding speed.

2. Provides the formation of frameless bays with the maximum preservation of the shape and density of the winding, in particular, due to the vertical arrangement of the axis of the drums, as this eliminates external mechanical influences when releasing the bays from the temporary winding frame (the neck of the drum has a variable radial size, the finished bay lies on motionless support - the released cheek of the unsupported node). This is a favorable condition for further transportation and packaging.

3. Eliminates the accumulation of extra meters of wound material during the transfer of winding from one drum to another.

4. Provides cutting of wound coils without stopping the winding process. Moreover, the moment of cutting does not require tight synchronization of the transition process.

The implementation of the invention

The design of the automatic coiler is based on the frame, which is a frame 1 (figure 1), consisting of horizontally located upper and lower plates 2, 3 and vertical racks 4. Between the upper and lower plates of the frame 1 is vertically arranged 5, including the engine 6 (linear movement mechanism), guides 7, drive 8, movable element 9. On the upper plate 2, the upper actuator 10 and the guides 11 of the upper movable platform 12 are fixed. On the lower plate 3, the lower actuator 13 and the guides 14 of the lower the lower platform 15. On the frame 1, the upper countertop 16, the lower countertop 17, the manipulator 18, the cut-off mechanism 19 are also fixed.

An upper gear motor 20 is mounted on the upper movable platform 12, the shaft of which is connected to the spindle 21, which serves to transmit torque to the upper drum 22 having an external flange 23.

On the lower movable platform 15, a lower geared motor 24 is fixed, the shaft of which is connected to the spindle 25, which serves to transmit the torque to the lower drum 26 having a detachable flange 27.

Between the reels 22 and 26 on the same vertical axis is placed support node 28.

The upper and lower countertops 16, 17 are located horizontally one below the other in the central part of the construction of the coiler. Over these worktops are guides 29, which are part of the manipulator 18, along which pushers 30 of the bays can move in the horizontal direction.

The mechanism of the segments 19 is mounted on the frame in the area of the support node 28.

Between the upper and lower countertops 16, 17, an elevator device 31 can be placed for transporting coils from the upper countertop 16 to the lower 17.

The support assembly 28 (Fig. 2) is an axis 32 on which bearings 34 are mounted through a spacer 33, tightened by the inner flanges 35 and the outer bearing caps 36. Cheeks 37 are rigidly attached to the flanges 35. This design allows independent rotation of the cheeks around axis 32 and a stop. The cheeks 37 of the supportless node are made with slots in the form of petals, with the same slope of each petal in this plane in one direction.

The upper drum 22 consists of a housing 38 (Fig. 3), around which a neck 39 is arranged in the form of a circular cylinder, cut vertically in three places, forming three sectors 40. Inside the housing 38 there are through horizontal holes located in three groups of vertically three pieces, each group being located in the zone of the vertical axis of symmetry of each sector 40 of the circular cylinder.

In the upper and lower holes are placed cylindrical parts 41 connected to the neck by screws 42, which play the role of radial guides. In each of the three middle holes there is a radial pusher 43, which on the one hand has the shape of a cylinder, like parts 41, and is attached to the neck with the same screw 42. And on the opposite side it has a flange 44 in the form of a truncated cone, and part radial pusher up to the flange is entwined with an elastic spring 45.

The outer flange 23 of the upper drum 22 is connected to the housing 38 by screws 46. At the lower end of the neck 39 there is a protrusion 47 of a cylindrical shape with a circular groove 48 at the base.

The spindle 21 is made on the basis of two main parts: the faceplate 49 and the axial follower 50, which is connected to the shaft of the upper gear motor 20 (i.e., the rotation motor) by a long screw 51, the head of which forms a centering protrusion 52, which plays an important role when connected to an unsupported assembly . The diameter D1 _{u of the} inner hole of the cheek 15 (FIG. 2) is equal to the outer diameter D1 _{in the} protrusion 47 of the neck of the upper drum (FIG. 3).

To prevent rotation of the shaft in the spindle, a key 53 with a rectangular section is provided, which is included in the corresponding recesses in the faceplate 49 and the axial pusher 50.

The rotation is transmitted from the spindle to the upper drum by means of the fingers 54, rigidly connected by screws 55 to the faceplate 49. The fingers 54 have an internal vertical stroke in the body of the housing 38 when the spindle is mechanically impacted from above. The elasticity of the stroke and the return of the spindle into place provides an elastic spring 56.

The lower drum 26 is made similarly to the upper drum 22 (Fig. 1) with the only difference that it does not have its own external flange, and its lower end is made in such a way as to enable the connection of the detachable flange 27 by analogy with the connection of the cheek of the support device. To do this, a circular groove 58 is made on the neck 57 (Fig. 4) for snapping a detachable flange 27 into it, and the neck body 57 slightly protrudes beyond the end of the drum body.

Tabletops 16, 17 (Fig. 5) have a cut-out part of the plane 59 in the shape of the outer contour of the cheeks 37 of the unsupported assembly. The guides 29 of the manipulator are located above the surface of each countertop, and the pushers 30 of the bays in the form of arcs have a coverage area at the level of the necks of the drums.

The mechanism of segments 19 (Fig. 1) is located in the vertical zone of the supportless device and contains a knife 60 (Fig. 6), a knife holder 61, a linear movement mechanism 62 and guides 63, along which the holder 61 can reciprocate through the bushings 64.

The elevator device 31 (FIG. 1) comprises a movable table 65 moving along a vertical rod 66 when the motor 67 of the elevator device is operating.

On the lower countertop 17 (figure 1) there are stops 68 that serve to stop the detachable flange 27 when it moves down as the outer flange of the lower drum.

Description of the operation of an automatic coil-breaker of a specific design

A cable is used as a long material, and a controller is used as a control device for the entire work process.

In the initial state, the unsupported assembly 28 (Fig. 1) is connected to the lower drum 26 by the lower cheek. In this case, the lower movable platform 15 is in its highest position, the springs 45 and 56 (Fig. 4) are compressed, the axial pusher 50 is advanced to its highest position and with its thickened part, the radial pushers 43 are bursting, which, in turn, press on the sectors 40, and the neck 57 therefore has a maximum radius value (different from the initial one by the value of the “neck stroke”). The upper end part of this neck 57 is attached to the lower cheek of the supportless device, and a detachable flange 27 is fixed in the groove 58 of the lower end part of the neck 57.

The upper cheek of the support assembly 28 is similarly attached to the upper drum 22, in which the outer flange 23 (Fig. 3) is non-detachable (rigidly fixed to the upper drum casing by screws 46).

The corresponding ends of the axial pushers in the form of centering protrusions 52 (Figs. 3, 4) with approach in the form of a truncated cone enter the central holes of the ends of the support unit (diameter D _c , Fig. 2). Thus, a rigid structure is formed on one vertical axis of two drums and an unsupported assembly between them.

The mechanism of segments 19 is derived from its core. The pushers of the manipulator are in the initial position. The movable table 65 (figure 1) of the elevator device 31 is located at the level of the lower tabletop 17.

The cable intended for rewinding into the bay is initially passed through the movable element 9 of the spreader 5 and its end is fixed in the lower part of the neck of the lower drum 26 near the outer flange. A command is issued from the controller to rotate the lower drum with an angular velocity that provides a given linear speed of the cable. The movable element 9 begins to produce reciprocating movements along the vertical axis within the neck of the lower drum. In this case, the cable is winded onto the lower drum 26 while simultaneously calculating the meter of winding and evaluating the remainder of the winding to a given cable length of the formed bay. A few meters before the end of the winding, a command is sent to the lower drum to turn on the upper gear motor 20 — the upper drum 22 begins to rotate in the same direction and at the same angular speed. After winding a predetermined amount of footage of the first bay, the spreader 5 is given a command to move the movable element 9 in the area of the unsupported assembly 28 with the maximum possible speed to the upper cheek of the unsupported assembly 28. The coiled cable when leaving the lower drum 26 falls first into the nearest slot of the lower cheek of the unsupported assembly 28, then into the nearest slot of the upper cheek of the support assembly 28 and falls onto the neck of the upper drum 22. In this case, the rotational speeds of both drums synchronously change to ensure a given line winding speed, and sets the corresponding speed of movement of the movable element 9 of the spreader 5.

From this moment, winding on the upper drum 22 begins, that is, the movable element 9 of the spreader 5 starts to make reciprocating movements along the vertical axis within the neck of the upper drum. After two rows of cable are wound on the upper drum, which is a guarantee of tight pressing of the lower row, a command is sent to the mechanism of the cuts 19 for fast horizontal movement into the cable cutting zone, and then the slow feed speed of the knife is set. The cable is cut over several revolutions of the reels. The resulting resistance moment during cable cutting does not affect the stability of the linear winding speed, since a modern electric drive, for example, based on the Control Techniques Unidrive-SP140 frequency converter, provides stable revolutions with a sharp change in the load moment over a wide range (www.controltechniques.com )

A sign of guaranteed cable cutting is the signal that the knife exits the cutting zone on the other hand. After that, the mechanism of segments 19 (Fig. 6) quickly removes the knife 60 from the cutting zone, a command is issued from the controller to stop the lower drum 26 and then lower the lower movable platform 15. This leads to disconnection of the lower drum 26 from the lower cheek of the unsupported assembly 28 in the next okay. At the initial moment of movement, the upper end part of the sectors is rigidly closed in the grips of the lower cheek of the supportless node, which prevents the drum body and neck from moving downward, and the lower axial pusher 50 moves down (Fig. 4). In this case, at the end of the stroke L, the radial pushers 43 under the influence of return springs 45 change the diameter of the neck of the drum to a minimum value, as a result of which the hook of the protrusion 47 with the groove 48 will leave the engagement zone with the lower cheek of the unsupported assembly 28 and be released. And the lower drum 26 (Fig. 1) together with the wound bay will begin to fall down until the moment when the external detachable flange 27 of the lower drum with the bay located on it reaches the stops 68 of the lower tabletop 17. The lower drum will lower further until it completely leaves the core bays, and the detachable flange, unfastened from the drum (similarly to the cheek of an unsupported device), will remain on the supports 68 and its upper surface, which is a support for the wound bays, will be practically at the same level with the surface Strongly countertops.

Then a command is given to the manipulator to start work and its pusher 30 (Fig. 5) shifts the bay to the tabletop and then to the movable table 65 of the elevator device 31, then the pusher 30 returns to its original position.

The controller instructs the raising of the lower platform 15. The lower drum 26 rises, connects a detachable flange 27, then the lower cheek of the unsupported assembly 28. And the winding of the bay continues on the upper drum 22. Upon reaching a certain number of meters when winding the upper bay, a command is issued to rotate the lower drum 26 at the same speed, and the cycle of switching the winding from one drum to another is repeated. The only difference is that the outer flange 22 is non-detachable, and when lifting the upper platform 2 with the upper drum 22, the wound bay remains lying on the upper cheek of the support device 28 disconnected from the upper drum. Then the manipulator 18 is also connected and moves the finished bay to the upper countertop 16.

The use of an elevator device provides the convenience of further packaging and transportation of bays from one level. For example, you can use a conveyor belt, mounted close to the countertop top.

It should be noted that the diameter of the cheeks of the supportless node should be larger than the diameter of the outer flanges of the drums in order to increase the reliability of the transition of the winding from one drum to another if the cable is wound around the neck of the drum as fully as possible, that is, up to the outer borders of the outer flanges.
