Description

  The present invention relates to a film fitting apparatus for fitting a tubular film such as a cap seal or a label onto a fitting body such as a bottle container, and more particularly to a film fitting apparatus suitable for a thin tubular film or the like.

  For example, a device as shown in FIG. 8 is disclosed as a label fitting device for fitting a cylindrical label L formed of a thin film to a body portion of a bottle container B. As shown in the figure, the film covering apparatus 80 is a cylindrical mandrel having a long belt-like label forming base material M in a state of being folded into a sheet shape in which cylindrical labels L are continuously connected. 81, while being opened in a predetermined state by being fitted to 81, the feed roller 82 feeds the lower part of the mandrel 81, and the cut unit 83 installed at the cutting position so as to surround the intermediate part of the mandrel 81 has a predetermined length. After the individual labels L are formed by sequentially cutting the individual labels L, the individual labels L thus opened are sequentially sent to the predetermined label fitting positions by the rollers 84, so that the individual labels L are sequentially conveyed to the label fitting positions. A label L is fitted on the body of the container B.

  As shown in the figure, the roller 84 is disposed in an inclined state with respect to the feeding direction of the label L, and the label L is rotated by rotating the label L sandwiched between the mandrel 81 and the label L. While L is rotated in the circumferential direction, it is sent out downward.

  Thus, when the label L is sent out downward while rotating in the circumferential direction, the cylindrical label L spreads outward in the radial direction, and the lower end side of the label L protruding from the mandrel 81 is less likely to be bent forward. Even if it is the label L formed with the thin film, there exists an advantage that it can be reliably fitted to the trunk | drum of the bottle container B. FIG.

  By the way, when the label L fitted on the mandrel 81 is sent out while being rotated in the circumferential direction as in the label fitting device 80 as described above, a label having a large diameter and a short cut length has no waist and a seat. Since it is easy to bend, it is desirable to increase the rotational speed of the label L in the circumferential direction to increase the shape retention by centrifugal force. Conversely, if the folding diameter of the label L is reduced, it is difficult to buckle. It is desirable to increase the delivery speed of the label L while minimizing the number of rotations in the circumferential direction. Also, the ease of buckling varies depending on the material of the label L.

  As described above, in the film covering apparatus according to the first aspect of the present invention, the shot roller is supported so as to be rotatable around the axis extending in the radial direction of the shot roller from the sandwiched portion of the tubular film by the shot roller in the mandrel. It is equipped with an angle adjustment mechanism that adjusts the tilt angle of the shot roller, so that the optimum rotation speed can be achieved by changing the tilt angle of the shot roller according to the diameter, length, and film material of the tubular film. And a cylindrical film can be fitted to a to-be-inserted body at a sending speed.

  Moreover, in order to determine the optimum inclination angle of the shot roller, the tubular film can be fitted with various inclination angles, so that the material of the tubular film, the slipperiness of the inner surface, the object to be fitted (container) The adjustment of the angle of inclination of the shot roller can be easily performed depending on the surface condition of

  Further, an operation display device 73 is connected to the label control device 1 </ b> A, and a label detection sensor 60 and a bottle detection sensor 62 are connected via sensor amplifiers 78 and 79.

  The label control device 1A is connected to a servo amplifier 74 that controls a pitch feed motor 10a that is a servo motor for rotationally driving the drive roller 11 of the base material feed unit 10, and includes a label detection sensor 60 and a bottle detection. When a control signal for rotating the drive roller 11 is output to the servo amplifier 74 based on the label detection signal and the bottle detection signal output from the sensor 62, a drive signal is sent from the servo amplifier 74 to the pitch feed motor 10a. As a result, the pitch feed motor 10a is driven, and the drive roller 11 rotates.

  The label control device 1A is connected to a servo amplifier 75 that controls a movable blade motor 30a, which is a servo motor for driving the movable blade 32, and labels output from the label detection sensor 60 and the bottle detection sensor 62. When a control signal for advancing and retracting the movable blade 32 is output to the servo amplifier 75 based on the detection signal and the bottle detection signal, a drive signal is output from the servo amplifier 75 to the movable blade motor 30a.

Is driven to rotate, and the shot roller 50 rotates.

  Hereinafter, operation | movement of this label covering apparatus 1 is demonstrated, referring the timing chart shown in FIG. First, in the standby state shown in FIG. 1, when the bottle container B is detected by the above-described bottle detection sensor (T0), the shot roller 50 starts to rotate, and the label L (fitted to the label shaping unit 25) By sending L1) downward while rotating in the circumferential direction, the bottle container B that passes through the label fitting position α is timed and fitted to the barrel. At this time, the shot roller 50 rapidly accelerates to the final peripheral speed Vc corresponding to the fitted speed, and then rotates at the final peripheral speed Vc for a predetermined time. Then, the rotation is stopped after the label L is separated from the shot roller 50 (T1).

  When the bottle container B is detected by the bottle detection sensor (T0), the label transfer means 40 also starts to drive, and the next label L (L2) gripped between the label opening 21 of the mandrel 20 Is started to the label shaping section 25 of the mandrel 20, and when the lower end of the label L (L2) reaches a position immediately before being gripped by the shot roller 50, the transfer operation of the label L is temporarily stopped (T2). At this time, the upper end of the label L (L2) is held between the feed belt 46 of the label transfer means 40 and the label opening 21.

  In addition, after the label transfer means 40 starts to be driven and until the label L transfer operation is temporarily stopped (T0 to T2), the base material supply unit 10 sends the label forming base material LM downward. Then, the label forming substrate LM is fitted into the label opening 21 of the mandrel 20, and the lower end of the label forming substrate LM is transferred to the lower half of the label opening 21 by the label transfer means 40, and the label is formed from the cutting position. The distance to the lower end of the substrate LM matches the label length. And while the label transfer means 40 stops driving, the base material cutting unit 30 cuts the label forming base material LM, so that the gap between the feed belt 46 of the label transfer means 40 and the label opening 21 is reached. The label L is separated while being held.

  When a predetermined time has elapsed after the label transfer unit 40 has stopped driving (T3), both the label transfer unit 40 and the shot roller 50 resume driving, and the upper and lower twos fitted on the mandrel 20 are restarted. The label L of the sheet is slightly transferred downward, and the lower label L (L2) is delivered from the label transfer means 40 to the shot roller 50. At this time, the moving speed Vb1 of the feed belt 46 of the label transfer means 40 and 1/2 of the peripheral speed Vc1 of the shot roller 50 are set to be substantially equal.

  As described above, when the shot roller 50 disposed in a state inclined by θ = 60 degrees with respect to the axis of the mandrel 20 is rotated, the label sandwiched between the mandrel 20 and the shot roller 50 Since L is sent downward at the peripheral speed Vc1 × cos θ = Vc1 / 2 of the shot roller 50, the delivery speed of the label L between the label transfer means 40 and the shot roller 50 is such that the label transfer means 40 and the shot roller 50 matches.

  However, in this label fitting apparatus 1, when the label L is delivered from the feed belt 46 of the label transfer means 40 to the shot roller 50, the feed belt 46 and the shot roller 50 do not grip the label L at the same time. The distance between the label transfer means 40 and the shot roller 50 is set so that the shot roller 50 can receive the label L after the toner has separated from the feed belt 46.

  The label transfer means 40 performs a stop operation (deceleration-stop) simultaneously with the separation of the label L from the feed belt 46. The shot roller 50 detects until the lower end portion of the label L is detected by the label detection sensor 60. The constant speed rotation is continued, and when the label L is detected by the label detection sensor 60 (T4), a stop signal of the shot roller 50 is output and a stop operation (deceleration-stop) is executed.

  In this way, the standby state shown in FIG. 1 is reached, and thereafter the same operation is repeated.

  As described above, in this label fitting apparatus 1, the shot roller 50 is supported so as to be rotatable about the axis extending from the ball roller 26 in the radial direction of the shot roller 50, and the inclination angle of the shot roller 50 is adjusted. Since the angle adjustment mechanism is provided, the label can be rotated at the optimum rotation speed and delivery speed by changing the inclination angle of the shot roller 50 according to the diameter, length, thickness, material, and surface state of the container. L can be fitted into the bottle container B.

  In addition, in order to determine the optimum inclination angle of the shot roller 50, the work of fitting the label L can be performed at various inclination angles, and therefore the adjustment operation of the inclination angle of the shot roller 50 can be easily performed. .

  In particular, in this film fitting apparatus 1, since the label L is sandwiched between the ball roller 26 attached to the mandrel 20 and freely rotatable in any direction and the shot roller 50, the shot roller 50 The ball roller 26 rotates in the direction corresponding to the inclination angle of the shot roller 50 even if the inclination angle of the lens changes, and the label L can always be sent downward while smoothly rotating.

Various driving means that can increase the rotational speed corresponding to the final fitting speed in a very short time after the driving is started can be employed. In particular, it is desirable to use a servo motor with good control accuracy of speed change during high-speed rotation.

  In each of the above-described embodiments, the ball shaping roller 25 is attached to the label shaping unit 25 of the mandrel 20 at a position corresponding to the shot roller 50. However, the present invention is not limited to this. It can be omitted. However, it goes without saying that it is desirable to provide the ball roller 26 in consideration of damage to the label L and the like.
