Description

[0001] Winding apparatus having tension regulation [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a winding apparatus, and more particularly, to a winding apparatus that winds a product so that a product such as a terminal strip, which is produced continuously and continuously, can be easily stored or transported.

There are products that are produced in a long direction in one direction. For example, when looking at the terminals for electrical connection, processing the base material through the progressive mold produces a terminal strip, which includes a plurality of terminals connected to each other by a carrier. That is, the terminals are not made individually but are produced in the form of terminal strips in which a plurality of terminals are connected to each other by a carrier. The carrier may then be cut and separated into individual terminals, or the entire terminal strip may be transported for subsequent processing.

Such long continuous products need to be rolled in the form of a roll for convenience of storage and transportation, and the winding device can be used to automatically wind the terminal. The winding device has a drum rotated using a motor, and when the drum rotates, the product is continuously wound on the drum.

However, in the process of winding the product using the winding device, the product may not be stacked straightly, or a part of the product may be folded during the winding process. This is because the product is wound around the product when it is wrapped with no tension applied to the product at all. To solve this problem, it is recommended to wrap the product in a state in which the product is tensioned to some extent.

On the contrary, when a tension is applied to the product, excessive tension may be applied in winding the product by the winding device. For example, when the product is not wound at a constant speed, or when the product is tangled during the winding process, or when the product is wound in the wrong direction by being moved to one side, a large tension may be generated in the process of winding the product.

In order to solve this problem, it is possible to put a sensor on the winding device so that when the product is subjected to too much tension, it may be detected and the winding operation stopped. However, since the sensor and the control unit only stop the winding operation, in order to rewind the product, the worker must correct the wrong state of the product or the winding apparatus and operate the winding apparatus again.

Also, depending on the sensitivity setting of the sensor, the winding device may stop frequently more than necessary, or conversely, an excessive tension may be applied to stop the winding device even if the winding device should stop.

It should be noted that, in adding reference numerals to the constituent elements of the drawings, the same constituent elements are denoted by the same reference symbols as possible even if they are shown in different drawings. In the following description of the embodiments of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the understanding why the present invention is not intended to be interpreted.

In describing the components of the embodiment of the present invention, terms such as first, second, A, B, (a), and (b) may be used. These terms are intended to distinguish the constituent elements from other constituent elements, and the terms do not limit the nature, order or order of the constituent elements. When a component is described as being "connected", "coupled", or "connected" to another component, the component may be directly connected or connected to the other component, Quot; may be "connected," "coupled," or "connected. &Quot;

The present invention is intended to wrap the workpiece (T) to facilitate storage and transportation. The present invention provides a structure that allows the workpiece T to be wound in a state in which the workpiece T is tightly stretched while giving a proper tension to the workpiece T and at the same time, when an excessive tension is applied thereto. Here, the workpiece T is elongated in one direction, and a terminal strip will be described below as an example. Of course, the workpiece T does not necessarily have to be a terminal strip but can also be applied when winding various workpieces T connected in a long continuous fashion.

According to the configuration of the present invention, the main frame of the present invention is formed by the main frame 10. The main frame 10 includes a main plate 11 in the form of a flat plate and a support portion 12 located under the main plate 11. The main plate 11 is erected on the support 12, in which all of the components described below are installed. Parts may be provided on the front and rear surfaces of the main plate 11, respectively. FIGS. 1 and 2 show the front surface of the main plate 11. FIG. The supporting portion 12 coupled to the main plate 11 may be configured to be able to easily move the entire main frame 10 with wheels.

A tension module 20, a sensing module 30 and a main roller 60 are installed on the main plate 11 constituting the main frame 10 and a feeder P May also be installed together. The tension module 20, the sensing module 30 and the main roller 60 provided on the main plate 11 are all exposed to the front of the main plate 11 and the work T is conveyed to the main plate 11 11).

2, the workpiece T is started from the tension applying module 20 and wound around the main roller 60 via the sensing module 30. [ During the winding process, the kanji P described below can be wound together. Here, the tension applying module 20 itself has a single roller shape. The workpiece T is wound on the main roller 60 while being wound around the tension applying module 20 first. This can be regarded as a case where the workpiece T is wound around the tension applying module 20 and rewound together with the separator P while being unwound to insert the separator P, T may be configured not to be pre-wound on the tension applying module 20 but to have a separate storage drum and pass the tensile force applying module 20 in the course of unwinding.

The tensile force applying module 20 applies a predetermined tensile force to the workpiece T so that the workpiece T can be wound in an unfolded state. To this end, the tension applying module (20) has a brake means (28) capable of generating tension. The tension applying module 20 is capable of adjusting the amount of tension applied to the workpiece T via the brake means 28 while applying tension to the workpiece T. [ That is, the breaking means 28 gives tension to the workpiece T by controlling the speed at which the tensioner module 20 rotates.

At the center of the tension applying module 20 is a first rotary shaft 21 for rotation and a tension hub 23 which is rotated about the first rotary shaft 21. The tension hub 25 is connected to the tension hub 23 via spokes. The workpiece T can be stored between the pair of tension ribs 25. When the tension hub 23 and the tension rim 25 are rotated, the stored workpiece T is released and is continuously moved toward the main roller 60.

The tension applying module 20 can apply tension to the workpiece T. The arrow F1 in FIG. 2 indicates a direction in which the tension applying module 20 applies tension to the workpiece T. The workpiece T can be wound in a tensioned state without being rolled in a loose state by applying such tension. Of course, even if the workpiece T is not given any additional tension, the driving speed of the main roller 60 may be increased or the tension may be generated even if the workpiece T is entangled. However, such a tension is difficult to predict It is necessary to manage the workpiece T because it may cause an excessive burden on the workpiece T.

3, it can be seen that a part of the tensile force application module 20 is installed on the rear side of the main plate 11 as well. The tension applying module 20 has a bearing 26 and a coupling device 27 connected to the first rotation shaft 21 and a brake means 28 connected thereto. The brake means 28 is for providing a load to the first rotary shaft 21, and can control the size of the load step by step. To this end, the brake means 28 may comprise a device capable of controlling the load. In this embodiment, the brake means 28 is a powder brake. The powder brake has a magnetic action by applying a magnetic force to the powder to form a chain-like cluster along a magnetic force line of the flank to generate a frictional force, thereby performing a breaking action. In this embodiment, the brake means 28 can adjust the load in five steps in total. Of course, it is also possible to adjust the load by using a gear assembly or a cylinder in addition to the powder brake.

The sensing module 30 is connected to the tensile force applying module 20. The sensing module 30 is a portion through which the workpiece T passes through the tensioning module 20 and is pressed against the workpiece T during the passage of the workpiece T, And serves to measure the tensile force applied to the workpiece (T). As shown in FIG. 2, the workpiece T passes through the sensing module 30 while being wound. Since the sensing module 30 is conveyed while the workpiece T is being wound around the sensing module 30, the sensing module 30 senses the amount of force applied to the workpiece T by sensing the force pressed by the workpiece T, You can do it.

The sensing module 30 measures the tension applied to the workpiece T in steps and controls the brake unit 28 according to the magnitude of the tension applied to the workpiece T So that the magnitude of the tension by the brake means 28 can be adjusted. The sensing module 30 can measure the magnitude of the tension stepwise, not simply ON / OFF, so that the winding device can be controlled according to each situation / condition.

The sensing module (30) of the present invention is installed in the main frame (10) so as to be linearly movable. The tensile force applied to the workpiece T while moving along the main frame 10 can be measured by the tension applied to the workpiece T. At the same time, It is possible to vary the magnitude of the tension applied to the tension member T.

The sensing module 30 can be roughly divided into a moving roller 31 and a sensing assembly 40. The moving roller 31 can move linearly to the main frame 10, (In the direction of arrow 1 in Fig. 2), and moves on the outer surface while the workpiece T is wound. Herein, it can be seen that the workpiece T is not moved to the moving roller 31 many times but moved in a state of being in close contact with the outer surface of the moving roller 31. [ The moving roller 31 is well visible on the front surface of the main plate 11 as shown in FIGS. The moving roller 31 rotates around the second rotating shaft 35 so that the workpiece T can be transported more smoothly.

Referring to the main plate 11, there is a moving roller 31 on the front side and a sensing assembly 40 on the rear side. The sensing assembly 40 is mounted on the rear surface of the main frame 10 and is connected to the moving roller 31 so that a part of the sensing assembly 40 linearly moves together with the moving roller 31, The magnitude of the tension of the water T can be measured. The moved configuration is returned to its original value when the tension of the workpiece T becomes small. 1 and 7, the main frame 10 and the base plate 41 have movement slots 15 penetrating them. The second rotary shaft 35 passing through the mobile slot 15 is connected to a moving plate 43, which will be described below, to operate the sensing assembly 40. The rollers R1 and R2 are provided around the moving roller 31 to facilitate the conveyance of the workpiece T. [

As shown in FIGS. 4 and 5, the base plate 41, which is installed on the opposite side of the main frame 10, forms the basic structure of the sensing assembly 40. The moving plate 43 and the guide block 44 provided thereon and the sensing angle 45 to be described below are disposed on the second rotating shaft 31 of the moving roller 31 35). Although the moving plate 43 is shown in FIG. 4, the moving plate 43 is omitted in FIG. 5 to show the internal structure.

The moving plate 43 is connected to the second rotating shaft 35 of the moving roller 31 and is linearly moved by the base plate 41. The moving plate 43 includes a guide block 44 coupled to the moving plate 43, Angle 45 also moves linearly. The moving plate 49 of the return means 47 is also engaged with the moving plate 43 so that the moving block 49 of the return means 47 when the moving plate 43 moves And the interlocking block 49 moves the piston rod 48 in and out of the cylinder.

On both sides of the base plate 41, there is a guide post 42, and a guide block 44 is coupled to the guide post 42. The guide block 44 is linearly moved along the guide post 42 and the guide block 44 is coupled to the moving plate 43 so that the moving plate 43 can be stably moved. The guide block 44 is composed of a total of four pieces, and the left two and the right two pieces are coupled to separate guide posts 42, respectively. Of course, the number of guide blocks 44 can be changed.

Sensor units 45 and 46 are installed in the sensing assembly 40. The sensor units 45 and 46 may be viewed as a part of the sensing assembly 40. The sensor units 45 and 46 may be moved linearly by the moving roller 31 and the second rotating shaft 35, In order to detect a change in position according to the position. As the moving plate 43 moves more and more, the tension applied to the workpiece T increases.

In the structure of the sensor units 45 and 46, the sensor units 45 and 46 include a sensing angle 45 and a sensor unit 46. The sensing angle 45 is connected to the moving plate 43 and moves together with the movement of the moving plate 43. As shown in the enlarged view of FIG. One of the sensing angles 45 is coupled to the moving plate 43, wherein the sensing protruding portion 45 '' bent at a right angle extends downward and is sensed as it passes the sensor unit 46. Reference numeral 45 'denotes a fastening hole for assembling to the moving plate 43.

The sensing protrusion 45 '' of the sensing angle 45 is sensed by the sensor unit 46 and the sensor unit 46 is composed of a plurality of horseshoe sensors 46a to 46d. The horseshoe sensors 46a to 46d are installed side by side along the mounting frame 41 'of the base plate 41 so that when the sensing angle 45 is moved, 46d. In this process, the moving state of the sensing module 30 can be known, and as a result, the magnitude of the tension applied to the workpiece T can be known.

In the present embodiment, the horseshoe sensors 46a to 46d are four in total. When the sensing angle 45 is at the initial position (the uppermost position in the drawing), the sensing angle 45 is detected by the horseshoe sensors 46a to 46d The sensing angles 45 are sequentially sensed by the four horseshoe sensors 46a to 46d in the course of the gradual movement of the sensing angle 45 And a horseshoe sensor 46d on the lower side thereof. Of course, the number of the horseshoe sensors 46a to 46d is not necessarily limited to four, and various types of sensors such as a laser sensor may be used in place of the horseshoe sensors 46a to 46d.

The sensing module (30) has a return means (47). The returning means 47 is for returning the moving roller 31 which has been moved due to the tension of the workpiece T to the sensing assembly 40. The returning means 47 has a certain resistance, The roller 31 may be regarded as a portion for supporting the sensing assembly 40 so as not to move linearly. That is, the returning means 47 resists the tensile force of the workpiece T transferred through the moving plate 43, while moving the moving workpiece T in accordance with the movement of the moving plate 43, The moving plate 43 is returned to its original position.

In this embodiment, the return means 47 is constituted by a pneumatic cylinder. At the end of the piston rod (48) protruding from the pneumatic cylinder, there is an interlocking block (49) connected to the moving plate (43). When the interlocking block 49 moves together with the moving plate 43, the piston rod 48 is inserted into the cylinder while overcoming the air pressure, and the sensing angle 45 is moved in the process. Of course, the return means 47 need not necessarily be a pneumatic cylinder, but may be made of an elastic material such as a hydraulic cylinder, a business assembly or a spring.

In this embodiment, the sensing module 30 is positioned between the tensioner module 20 and the main roller 60, and the tensioner is positioned at a position outside the shortest path between the main roller 60 and the tensioner module 20 Respectively. This is to allow the workpiece T to change its conveying direction while passing through the sensing module 30, and appropriate tension may be added to the workpiece T in the process.

The tension applying module 20 and the sensing module 30 are controlled by the control means. The control means controls the brake means 28 provided in the tensile force application module 20 to reduce the tension when the tension of the workpiece T detected by the sensing module 30 is equal to or greater than a set value . That is, the control means determines the magnitude of the tension applied to the workpiece T according to the position of the sensing angle 45 sensed by the sensor unit 46, The size of the tension can be adjusted. The control means may be installed separately or may be integrally coupled to the tension module 20 or the sensing module 30. [

1 and 2, the base plate 41 is provided with a main roller 60. The main roller 60 rotates about the third rotary shaft 61 and the workpiece T is wound on the main hub 63 and the main rim 65 of the main roller 60 during the rotation process . The workpiece T can be stored or transported while being wound around the main roller 60. [ A motor (not shown) is provided on the main roller 60 to provide a rotational force. In this embodiment, there is no motor in the tension applying module 20 or the sensing module 30, and the workpiece T is wound only by the driving force of the motor of the main roller 60. [

On the main surface of the main roller 60, there are devices for feeding the separator P. That is, at a position adjacent to the main roller 60, there is the intermittent feeding roller 70 for providing the interleaving paper P between the workpieces T wound around the main roller 60, Is fed through the separable feeder 90 and wound together with the main roller 60 in a state of being overlapped with the workpiece T. The width feeder 90 cuts the ply sheet P to an appropriate length while feeding the ply sheet P and the width adjusting device 80 located below the ply feeder 90 cuts the right and left sides of the ply P appropriately So that the kanji P can have a proper width in accordance with the size of the workpiece T. [ Reference numeral R3 denotes a roller that smoothly feeds the separator P.

Next, a process of moving the workpiece through the invention will be described.

First, when the main roller 60 rotates, the workpiece T is wound on the main roller 60, and the tensioner is gradually wound on the module 20 while being wound. The workpiece T is continuously wound on the main roller 60 while continuously moving from the tension applying module 20 to the main roller 60 through the sensing module 30. [ At this time, it is preferable that the workpiece T is wound in a tightly stretched state so as not to be entangled or shifted during the winding process. In the present invention, the tensioner module 20 serves as the tension. Reference numeral 50 denotes an aligning device for aligning the workpiece T in width.

The breaking means 28 of the tension applying module 20 can add a total of 5 steps of tension to the workpiece T. In the initial state, the highest one-step tension is applied. Therefore, the workpiece T begins to be wound in an unfolded state. The breaking means 28 gives tension to the workpiece T by controlling the speed at which the tension applying unit 20 rotates the first rotary shaft 21. [ That is, when the rotation speed of the tension applying module 20 is lowered due to the brake means 28 while the main roller 60 is continuously rotating, the tension of the workpiece T is increased and spread.

If the workpiece T is tangled or folded in this state, the workpiece T can not move smoothly and the tension increases in the process. The increased tension is a great burden on the workpiece T, and in severe cases, it may be broken or damaged. Therefore, appropriate measures are necessary. The present invention can solve this situation by automatic control.

Specifically, an increase in the tension of the workpiece T becomes a force for moving the sensing module 30. [ The sensing module 30 has a structure capable of moving along the mobile slot 15. When a force is applied to the sensing module 30 in the direction F2 in FIG. 2 by the workpiece T, 47). In this configuration, the second rotary shaft 35, the moving plate 43, the sensing angle 45, the interlocking block 49, and the guide block 44 move simultaneously. The second rotary shaft 35, the sensing angle 45, the interlocking block 49 and the guide block 44 are both coupled to the moving plate 43 and move together.

When the moving plate 43 moves while overcoming the resistance of the return means 47, the sensing angle 45 passes through the first horseshoe sensor 46a, starting from the initial stage of the first horseshoe. The control means controls the brake means 28 of the tensile force application module 20 so that the tension of the workpiece T is increased to a certain degree by the second horseshoe passing through the first horseshoe sensor 46a. Control reduces friction. When the frictional force of the brake means 28 is reduced, the tension applied by the tension applying module 20 is reduced by one step to two stages.

At this time, the sensing module 30, which is in contact with the workpiece T, can linearly move along the path of the mobile slot 15 to reduce the tension applied to the workpiece T. [ The tensile force applied to the workpiece T can relieve the sensing module 30 even if the tensile force application module 20 is not actuated. It is possible to reduce the size of the tension more easily.

In this case, the state of entanglement or the like of the workpiece T can be released. However, if the tension applied to the workpiece T still increases, the next step proceeds. That is, the second rotary shaft 35, the moving plate 43, the sensing angle 45, the interlocking block 49, and the guide block 44 move at the same time. When the moving plate 43 in the second stage moves further while overcoming the resistance of the return means 47, the sensing angle 45 passes the second horseshoe sensor 46b and passes through the second horseshoe sensor 46b The moment becomes three stages. This means that the tension of the workpiece T has increased more, so that the control means controls the brake means 28 of the tensioning module 20 to further reduce the frictional force. When the frictional force of the brake means 28 is reduced, the tension imparted by the tension applying module 20 is reduced by one step to three stages. Such a state is shown in Fig.

The sensing module and the tension applying module 20 can be controlled until the fifth step. 7 shows the fifth step. In the fifth step, the sensing module 30 itself moves most, and thus the tension of the workpiece T hanging on the sensing module 30 can be reduced to some extent The tension applied to the workpiece T by the tension applying module 20 and the sensing module 30 is minimized because the control means reduces the resistance of the break means 28 to five steps. Therefore, the abnormal state of the workpiece T can be solved.

As described above, according to the present invention, the workpiece T can be wound in a tight state because the tension applying module 20 pulls the workpiece T appropriately, and if the tension is excessively applied, The tension applied by the tension module means can be reduced. Therefore, the winding apparatus according to the present invention not only uniformly winds the workpiece T, but also a certain level of error or malfunction can be solved by the winding device itself.
