The present invention relates to a wire fixing means having a function of detecting a tension of a driving wire in a door apparatus used in a production line such as an automobile sheet metal line, and a wire driven door apparatus having the fixing means. After the lifting or lowering operation is completed, if the drive wire is continuously released from the winch unit due to a malfunction such as a limit switch or the tension applied to the wire is removed as the wire is short-circuited, it is detected quickly, thereby maintaining and maintaining the door device. The present invention relates to a wire fixing means having a wire tension sensing function and a wire-tight door having the same, to facilitate the operation, and in particular, to smoothly proceed the operation of the production line using the door device.

The door device for opening and closing of a specific space is operated in various forms according to its driving type. For example, it is used in production line such as automobile sheet metal line or painting line, and its length is long and the door is opened for utilization of space. In the case of a door that is opened and closed in a lifting form without opening and closing a furnace, a wire-driven door device that realizes the rising and falling of the door using a driving wire is mainly used.

On the other hand, Figures 1 to 3 show an example of such a known conventional wire-driven door device.

For example, in FIG. 1 and FIG. 2, the overall configuration of the door device is shown in front and rear view. Such a conventional wire driven door device 200 has a predetermined length along the side of the column 202. Guide pulleys 206 disposed on the left and right sides of the frame 240 formed of vertically supported supporting steels 204a and plates 204b connected therebetween are connected to both upper sides of the door 208.

In addition, the guide pulley 206 is fixed and wound on one end and the other end of the wire fixing bracket 212 and the winch unit 214 (winch unit) respectively installed on the left and right sides of the upper base 210 of the upper column The wire 216 is supported as it passes through.

Therefore, as shown in FIGS. 1 and 2, when the motor 214a of the winch unit 214 on the upper base 210 is driven, the driving wire 216 wound on the connected driving drum 214b is pulled up or As it is released and lowered, the door 208 under the guide pulley 206 is raised or lowered integrally with the operation of the driving wire.

On the other hand, Figure 3 shows a conventional wire-driven door device 200 as a side view, according to the operation of the drive wire 216 passing through the guide pulley 206 in accordance with the operation of the winch unit 214. When the lower door 208 of the guide pulley 206 is raised or lowered, the column 202 corresponding to the highest position of the door and the lowest position of the door has upper and lower limit switches for adjusting the raising and lowering of the door. 218 and 220 are respectively provided, and the top and bottom limit switches 218 and 220 are operated on the upper portion of the door 208.

Accordingly, when the door 208 is raised or lowered, the tooth bar 222 quenches the upper limit switch 218 or the lower limit switch 220, and when the limit switches are operated, an electrically connected winch As the drive motor 214a of the unit 214 is stopped, the raising or lowering operation of the door 208 is adjusted.

However, the following problems occur in the conventional wire-driven door device 200 as described above.

For example, the work environment of the line in which the door device 200 is installed, for example, in the case of automobile sheet metal or painting line, various fly products, dust, or other foreign substances generated during the work are the upper and lower limit switches 218. It is easy to attach to 220, and therefore malfunction of the limit switches 218 and 220 easily occurred.

Accordingly, even when the door 208 of the device is lowered to the bottom (bottom), the lower limit switch 220 does not operate normally, and eventually the drive motor 214a of the winch unit 214 electrically connected to the limit switch. Although the lowering of the door is completed, the driving wire 216 is continuously released from the driving drum 214b while continuing to operate.

In this case, in order to return the part of the drive wire 216 loosened more than necessary from the drive drum of the winch unit to the initial position for normal operation, a lot of manual work and time should be put into place. Operation, of course, affects the operation of the production line including the door device.

On the contrary, if the operation of the winch unit is caused by a malfunction of the upper limit switch 218 even after the lift of the door is completed, the motor of the winch unit is overloaded or the driving wire is excessively pulled, resulting in short circuit of the wire or equipment failure of the device. Was to cause.

Accordingly, a malfunction of the limit switch that controls the rising and falling of the door in the wire-driven door device occurs, causing the drive wire to be loosened or excessively pulled from the winch unit more than necessary, resulting in a short circuit of the wire, thereby eliminating tension of the wire. At this moment, it will be desirable to detect this and stop the operation of the drive wire, since the loosening of the drive wire from the winch unit will not continue or the equipment will be prevented from damage.

The present invention is to solve the various problems as described above, the moment the tension of the lifting drive wire of the door is removed, it is quickly sensed by adjusting the operation of the drive wire, thereby facilitating subsequent processing of the door device In addition, the operation of the production line itself, such as automobile sheet metal, painting lines, etc., using wire-driven doors can be performed smoothly. In particular, a frame or elastic body that flows when the drive wire is removed is guided or seated. The present invention provides a wire fixing means having a wire tension sensing function and a wire-driven door device having the same, which are supported by a negative portion and have a constant frame lift to increase the operation precision of the sensor.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

First, Figure 4 and Figure 5 shows a wire fixing means (1) having a wire tension detection function according to the present invention.

That is, as shown in Figures 4a and 4b, the wire fixing means 1 of the present invention is pulled or released by a drive means, for example, a winch unit (commonly used for driving the wire) or the like On the moving base, that is, the driving wire 10 for elevating (raising or lowering) the door or the like described in detail from the following FIG. 6 and the moving path of the drive wire 10, for example, on the upper base of the door device. The fixed frame 30 installed in the, and the flow frame 50 is seated so as to flow through the elastic body 40 on the fixed frame 30, the drive wire 10 is connected, and the fixed frame Tension which is installed in the 30 and the drive wire 10 is continuously released from the drive means such as the winch unit due to a malfunction of the limit switch, and the wire is shorted while being loosened or excessively pulled and acting on the drive wire 10. Removed moment is constituted by a sensor 70 which is actuated by fluid flow frame.

At this time, as shown in Figure 4c and 4d, the fixed frame 30, the guide rod 32 for guiding the vertical flow through the flow frame 50 vertically, and of the flow frame 50 It is provided with a seating block 34 on which the elastic body 40 which the bottom surface contacts is seated.

In addition, the seating block 34 has a hollow shape in which the elastic body 40, for example, a spring is embedded therein.

In addition, as shown in Figure 4b and 4c, the flow frame 50, the first horizontal frame 54, the wire socket 52 is fixed to the lower end of the drive wire 10 is fixed and The vertical frame 56 supporting the first horizontal frame 54 is installed on the upper portion and seated on the elastic body 40, and includes a second horizontal frame 58 through which the guide rod 32 passes. Consists of.

At this time, the second horizontal frame 58 of the flow frame 50 is formed with holes (58a) through which the guide rod 32 on the fixed frame 30 passes, the bottom of the spring is the elastic body The fixing groove 58b which is fitted and seated is formed.

And, the upper end of the guide rod 32 is fastened to the nut (32a) to block the separation of the flow frame.

In addition, as illustrated in FIGS. 4A and 4B, a through hole 58c through which the driving wire 10 passes through the center portion of the second horizontal frame 58 and the fixed frame 30 of the floating frame 50. ) 30a are formed.

As shown in FIG. 4A, the drive wire 10 is wound around the wire fixing socket 52 and connected and fixed as a fastener 52a.

As shown in FIGS. 4A and 4B, the sensor 70 has the second horizontal frame when the second horizontal frame 58 of the floating frame 50 is adjacent and the tension of the driving wire 10 is removed. When the frame 58 is raised by the spring that is the elastic body 40, it may be a proximity sensor that is operated.

Therefore, when looking at the operation of the wire fixing means 1 having a wire tension detection function of the present invention, for example, a moving body associated with the drive wire 10, for example, the door as shown in FIG. At the time of elevating, the tension of the drive wire 10 is, as shown in Figure 4a, because the drive wire 10 is pulled, the tension (F) acts.

As described above, however, even after the movement of the movable body is completed, the tension F is removed when the winch unit serving as the wire driving means continues to operate due to a malfunction of the limit switch and the driving wire 10 is loosened.

On the contrary, if the driving wire is excessively pulled and shorted due to a malfunction of the upper limit switch, the tension F acting on the wire is removed even in this case.

Therefore, as shown in FIG. 5, when the driving wire 10 is loosened or short-circuited and the tension acting on the wire is removed, the compressive force for pressing the flow frim 50 connected to the driving wire 10 is lost. Therefore, the tension body (F) acts on the elastic body 40 interposed between the fixed frame 30, that is, the driving wire 10, and the elastic body 40, which is compressed due to the lowering of the flow frame, has the flow frame 50 with elastic force. Raise upward along the guide rod (32).

That is, in FIG. 5, the second horizontal frame 58 of the flow frame 50 positioned adjacent to the sensor 70 moves from the position of P1 to the position of P2, and at this time, the sensor 70 installed in the fixed frame 30. That is, the proximity sensor is activated and stops the driving of the drive motor of the winch unit shown in detail, for example, the driving means electrically connected through the control unit (panel) of the device (not shown).

Therefore, the wire fixing means 1 having a wire tension detection function of the present invention has a simple structure as a whole, and immediately detects when a driving wire that is operated when a moving object, such as a door, is lifted or abnormally loosened or short-circuited and no tension acts on the wire. By stopping the operation of the drive wires, it is possible to fundamentally solve the conventional problems.

Next, FIGS. 6 to 12 show the wire-driven door apparatus 100 of the present invention having the wire fixing means 1 having the wire tension sensing function of the present invention described above, wherein the wire fixing means 1 The components of) are denoted by the same reference numerals, and the description of the operation of the wire fixing means 1 is briefly described below.

First, in FIG. 6 to FIG. 8, the overall configuration of the wire-driven door device 100 of the present invention is shown in plan, front and rear views thereof.

That is, as shown in Figures 6 and 8, the wire-driven door device 100 of the present invention, is installed on one side on the upper base 120 spanning the pillar 110, the drive wire 10 Wire fixing means (1) having a tension sensing function of the wire while the one end is connected and fixed, the winch unit 130 is installed on the other side on the upper base 120 and the other end of the driving wire (10), The door 150 which is operated upward or downward from the lower side of the upper base 120 while the wire guide pulleys 152 through which the driving wire 10 passes, are connected between the fixing means 1 and the winch unit 130. ) Is configured to include.

Accordingly, the other end of the driving wire 10 having one end connected to the wire fixing means 1 in the door device 100 of the present invention is wound around the driving drum 134 of the winch unit 130, and eventually the winch unit When the driving motor 132 is operated, the driving wire is pulled or released according to the driving of the winch drum 134, and the door 150 connected to the lower portions of the guide pulleys 152 on both sides through which the driving wire 10 passes. ) Is lowered when the drive wire is unwound from the winch unit, and rises when the drive wire is wound around the winch unit.

At this time, although not shown by a separate code, the door 150 is connected to the frame of the frame and the inner frame of the outer frame on which the wire guide pulley 152 is mounted, the front and rear of the channel and the plate 7 and 8, when the door 150 descends to seal the space, a transparent plate or the like may be installed to view the inside of the rubber plates.
