Description

TECHNICAL FIELD [0001] The present invention relates to an emergency stop device for an automatic vinyl packaging machine,

The present invention relates to an emergency stop device for an automatic vinyl packaging facility, and more particularly, to an emergency stop device for an automatic vinyl packaging facility capable of automatically stopping the operation of the automatic packaging line, ≪ / RTI >

In general, packaging is used to procure products such as food or things necessary for living, and to protect, store, move, distribute or exchange these.

That is, the packaging is used for preventing the inflow of foreign matter and preventing damage to the appearance of the product until the product is provided to consumers.

Currently available means for packaging food include vinyl, cans, bottles, PET, paper, and plastics.

Among these means for packaging food, vinyl is mainly used in packaging low-priced and wrinkled products.

In general, plastic wrapping paper is widely used as a packaging bag for various foodstuffs and parts due to its low cost, excellent sealing property and airtightness.

Currently, the vinyl used for vinyl wrapping in the automatic vinyl wrapping facility is fed from the roll to the vinyl in a state of being opened in the front and back, or is fed from the roll to the vinyl in the sheet. After the operator inserts the product into the vinyl, And sealing each end portion of the vinyl in the longitudinal direction or by sealing the vinyl in the widthwise direction and in the longitudinal direction at both ends of the vinyl.

On the other hand, when the automatic parting system using the automated vinyl packing equipment is operated, if the part stops moving due to the foreign matter being stuck on the part such as the supply roll or the bonding roll, if the continuous operation with the peripheral part is not stopped, Damage, line tangling, etc. In such a case, it is essential to operate the system to quickly stop the entire line.

4 is a cross-sectional view showing an emergency stop device applied to a conventional automatic vinyl packaging facility.

4, the emergency stop device includes a ball 110 and a plunger 120 rotating together with an axis 100 for driving a roll, and a proximity sensor (not shown) is disposed at one side of the plunger 120 The ball 110 presses the plunger 120 and the proximity sensor 130 senses the protrusion operation of the plunger 120 at this time. And the line is stopped by the output control of the controller (not shown) by the detection signal of the proximity sensor 130. [

Here, the structure for pressing the plunger while pushing the ball by the torque acting on the shaft is the same as that of the general emergency stop device, so a detailed description will be omitted.

However, in the conventional emergency stop device, when a ball or plunger is operated by a torque when a line abnormality such as a foreign matter is caught between rolls, a motion sensor senses the action of the ball & The time difference between the time point at which the line abnormality occurs and the time point at which the line is stopped (time difference by the rotation angle of the ball and plunger) occurs.

That is, until the proximity sensor detects the plunger protruding outwardly, the proximity sensor senses only after 180 ° when the plunger is 2 or 360 ° when the plunger is 1, The sensing operation of the proximity sensor is performed at a time difference of.

As a result, even during such a period of time, the lines continue to operate in the peripheral process part, and the load on the entire line is liable to be incurred because the vinyl or the like becomes more entangled or interference occurs between the progressive parts, There is a problem in that the facility operation rate is lowered and the productivity is lowered, as well as the efficiency of facility operation is remarkably deteriorated.

FIG. 1 is a perspective view showing an emergency stop device of an automatic vinyl packaging facility according to an embodiment of the present invention, and FIG. 2 is a front view showing an emergency stop device of an automatic vinyl packaging facility according to an embodiment of the present invention.

As shown in FIGS. 1 and 2, the emergency stop device senses the movement of the joint roll and the drive shaft lifted up by a foreign object or the like, and then immediately stops the entire facility with the detection signal at this time Lt; / RTI >

To this end, the emergency stop device comprises two upper and lower bonding rolls (not shown) mounted on an automatic vinyl packaging line of the automatic vinyl packing facility and sealing the longitudinal end of the vinyl package containing the product.

The two bonding rolls are arranged in a structure in which the two bonding rolls are coupled to two driving shafts 11 arranged side by side while being rotated up and down, and each of the bonding rolls is provided with a bar heater (not shown) The vinyl package is sealed in a form in which the vinyl is fused.

Here, the driving method of the bonding roll including the drive shaft, the bonding method using the heater, and the like are the same as the driving method and the bonding method of the general automatic vinyl packing equipment, and thus a detailed description thereof will be omitted.

Further, gears 10, which are meshed with each other and are rotated by means for receiving power, are mounted on the ends of the upper and lower drive shafts 11, respectively.

Particularly, in the present invention, the driving shaft 11 of at least one of the two bonding rolls, for example, the driving shaft 11 of the bonding roll disposed at the upper side, can be structured to be vertically movable, The sensor 12 senses the movement of the drive shaft 11 including the drive shaft 11, thereby immediately stopping the operation of the entire equipment in the event of a line abnormality such as a foreign object jamming or jamming.

A rear end portion of the shaft block 14 is disposed on the frame 100 at a position adjacent to the both ends of the drive shaft 11 and the rear end portion of the shaft block 14 is supported by the hinge shaft 13 So that the axial block 14 is installed to be rotatable about the hinge shaft 13 at the rear end portion.

Both end portions of the drive shaft 11 are coupled to each other at a right angle through the central portion of both shaft blocks 14 and a bearing 23 is interposed at the coupling portion. The end portion of the shaft block 14 can freely rotate freely with respect to the shaft block 14 and can be simultaneously heard during the rotation of the shaft block 14. [

In other words, the shaft block 14 can be rotated around the hinge shaft 13 at the rear end so that the joining roll and the driving shaft 11 are lifted up.

Here, the rotation of the shaft block 14 means that the tip of the shaft block 14 is lifted up.

A spring block 15 is installed on the frame 100 below the front end of the shaft block 14. A spring pin 16 is vertically erected on the spring block 15, Respectively.

At this time, the upper end portion of the spring pin 16 can be extended upwardly through a hole (not shown) at the tip end of the axial block 14, So that the spring sheet 18, which will be described later, can be fastened.

A spring 17 is disposed around the upper end of the spring pin 16. The spring 17 is engaged with the bottom surface of the spring seat 18 fastened to the upper end of the spring pin 16, And a spring seating groove 22 formed on the upper surface of the front end portion of the housing.

As a result, the spring 17 can always push the lower end of the lower shaft block 14 downward while exerting its elasticity with the upper spring seat 18 as a fulcrum. As a result, The tip end of the lifted axial block 14 can be returned to its original lower position.

In this case, the elastic force of the spring 17 can be adjusted. For example, when the position of the spring seat 18 fastened to the screw portion of the spring pin 16 is adjusted up and down, So that the elastic force of the spring 17 can be adjusted in accordance with the adjustment of the position of the spring seat 18.

For example, it is possible to loosen the elasticity of the spring 17 by loosening and lifting the spring seat 18, and conversely, by tightening the spring seat 18 and downward, it is possible to tighten the elasticity of the spring 17.

The stopper pin 21 is provided as a means for restricting the position (posture) of the shaft block 14.

The stopper pin 21 may be formed in a form of a bolt and is positioned at one side of the spring block 15 and maintains a vertical posture parallel to the spring pin 16. In this state, And is installed as a fastening structure.

The upper end of the stopper pin 21 installed in this way receives the spring force to support the bottom surface of the front end of the shaft block 14 pressed downward. As a result, as the stopper pin 21 supports the bottom, ) Will be able to maintain a flat-bottom level as downward movement is regulated.

Of course, when adjusting the fastening state of the stopper pin 21 to adjust its height, the posture of the shaft block 14 can be varied.

In particular, the sensor block body 20 and the sensor 12 are provided as means for substantially sensing motion.

The sensor block body 20 includes a bracket 20a, a block 20b, a pin 20c, a sensing adjusting body 20d, and the like.

The bracket 20a is installed at the front end of the shaft block 14 and the block 20b is fixed to the front surface of the sensor bracket 19 with a vertical shaft. The pin 20c is inserted into the hole in the block 20b And is structured so as to be movable up and down while being supported by the resilient force of the pin spring 20f.

At this time, the lower end of the pin 20c comes into contact with the upper surface of the distal end portion of the bracket 20a.

The sensing adjuster 20d is in the form of a cylindrical ring, and its position can be fixed by the set screw 20e, which is inserted into the pin 20c and is coupled to the side.

At this time, the sensing adjusting body 20d can be adjusted in position on the pin 20c through the tightening and releasing operations of the set screw 20e. By adjusting the position of the sensing adjusting body 20d, The sensing range of the sensor 12 that senses the movement of the sensor 12 can be changed.

The sensor 12 is a kind of proximity sensor which is installed in a structure in which the sensor bracket 19 provided on the frame 100 supports the sensor bracket 19 while maintaining a horizontal posture, The sensing adjusting body 20d in the sensor block body 20 can be located immediately in front of the sensor body 20.

Accordingly, when the sensing adjusting body 20d of the sensor block body 20 which is provided at the tip of the shaft block 14 and moves upward together is positioned in front of the sensor 12, At this time, the detection signal is sent to the controller (not shown). As a result, the entire automatic vinyl packaging facility can be immediately stopped by the output control of the controller.

Here, a method of stopping the operation of the entire automatic vinyl packing apparatus by the output control of the controller that receives the signal of the sensor is not particularly limited as long as it is a method commonly known in the art.

Meanwhile, a set including a shaft block, a spring, a sensor block body, a sensor, etc., which is a means for sensing the structure and motion of the joint roll and the drive shaft, is provided with two sets, one set for each of the drive axes, It is desirable to be able to accurately detect the movement while stably supporting the roll and the drive shaft.

Accordingly, the operation state of the emergency stop device of the automatic vinyl packaging apparatus having the above structure will be described below.

3 is a front view showing an operation state of an emergency stop device of an automatic vinyl packaging facility according to an embodiment of the present invention.

As shown in Fig. 3, in the situation where each step of the packaging line according to the operation of the automatic vinyl packing facility progresses sequentially, the operation of the upper and lower bonding rolls (for example, A heat-sealing operation is performed by engaging with each other while interposing the heat-sealing resin between the heat-sealing resin and the heat-sealing resin.

In this process, when an abnormality such as a foreign substance is caught between the upper and lower bonding rolls which are engaged with each other or a plurality of vinyl packages are piled up and formed, the upper bonding roll is lifted up corresponding to the foreign object, The drive shaft 11 is also lifted up.

When the drive shaft 11 including the bonding roll is lifted up, the shaft block 14 coupled to the end of the drive shaft 11 rotates around the hinge shaft 13 at the rear end, It will be heard up.

When the distal end of the shaft block 14 is lifted up, the sensor bracket 20a at the distal end of the shaft block 13 pushes up the pin 20c so that the pin 20c is lifted up I will go.

Subsequently, the sensor 12 located on one side of the upper and lower movement lines of the sensing adjusting body 20d senses the presence of the sensing adjusting body 20d. At the same time, the sensing signal of the sensor 12 is supplied to the controller The entire line can be stopped while the operation of the whole facility is immediately stopped by the output control of the controller.

As a result, the entire line is immediately interrupted at the same time as the line abnormality occurs, so that it is possible to prevent equipment damage, product damage, line tangle, safety accident, etc., The follow-up can be made as easy as that.

As described above, in the present invention, a new system capable of quickly stopping the entire line can be realized by detecting the movement of the joint roll and the drive shaft moving in conjunction with the occurrence of an abnormality such as a foreign material between the joint rolls in the automated vinyl packaging line Thus, it is possible not only to protect the facility but also to prevent a safety accident, and to operate the system efficiently.
