Description

Automatic cutting and packaging equipment for roll film materials

The present invention relates to an automatic dispensing apparatus for a film material, and more particularly to a film material roll capable of automatically and continuously winding and cutting a roll film material for winding a roll film material into a predetermined length. Automatic cutting and dispensing equipment.

Many of the known film materials are stored and transported in a roll form after the initial production, and the roll film material is generally called a raw material roll, and the length and weight of the raw material roll are very large and Not suitable for direct sale to end consumers, so for some roll-type film materials such as thermal insulation paper that need to be further packaged for retail, further packaging and cutting according to the length or retail unit required for retailing is required.

A retracted device of the Republic of China, No. M430468, "Retracting Device", which discloses a retracting device comprising at least two rollers; a lifting unit disposed on one side of each roller; and a combination with the lifting unit Corresponding to the retracting unit disposed between the two rollers, comprising a connecting tube disposed on the lifting unit, a hollow reel connected to the communicating tube and located between the two rollers, and a plurality of suction holes disposed on the hollow reel . Thereby, it can be taken up as a film material (such as heat insulation paper), so that each roller drives the hollow reel of the retracting unit to rotate, and at the same time, the hollow reel generates a suction force, and the film material is made up of the roller and the hollow reel. When interposed, the hollow reel is used to attract and retract the film material, thereby achieving the advantages of saving the winding time, accurately controlling the winding length, and eliminating the need for secondary leveling.

In the case of the film material T, the platen 81 is lifted again to the standby position above the film material T, and then the second actuator 672 moves the support frame 83 again to return the platen 81 and the platform 82 to the normal position of "11A" (between Between the driving path of the driving roller 13 and the double-edged blade 31, returning to the winding operation stage of the film material T, the continuous and continuous operation can automatically and continuously cut the film material of the roll film. The film is cut into a predetermined length, and the film material T having a predetermined length after cutting is taken up into a film material roll TC.

Please refer to FIG. 12 to FIG. 13 for a structural block diagram and a structural view thereof according to another embodiment of the present invention, further including: a force control mechanism 90 for detecting between the discharge reel 11 and the driving roller 13. The tension of the film material T controls the rotation speed of the first driving unit 61 of the material supply mechanism 10 according to the magnitude of the tension, so that the film material T between the take-up reel 11 and the driving roller 13 is maintained within an appropriate tension range, thereby maintaining The film material T is wound up in the winding mechanism 20 into a winding quality of the film material roll TC.

An embodiment of the tension control mechanism 90, as shown in FIG. 13, includes at least: a movable idler 91, a tractor 92, and a position detector 93; wherein the movable idler 91 is disposed on the film material T A conveying path between the reel 11 and the driving roller 13, one embodiment of which is to arrange the movable idler 91 between the unwinding reel 11 and an idler 12 adjacent thereto, and the retractor 92 is a traction capable of providing a long state. One embodiment of the retractor 92 may be any one of a tension spring, a pneumatic cylinder, and a pneumatic telescopic rod; in one embodiment of the invention, the retractor 92 is a pneumatic element, specifically Like an adjustable damping pneumatic telescopic rod (described in detail later), one end of the retractor 92 is connected to a fixed position that is relatively stationary with the reel 11 The other end of the tractor 92 is rotatably connected to one axial end of the movable idler gear 91, and two axial directions of the movable idle gear 91 are provided for balance. The position detector 93 is connected to the end to detect the change of the position of the movable idler 91, and transmits a signal indicating the change of position to the control unit 50. The embodiment of the position detector 93 may be a type. Any one of a linear variable resistor, an optical scale, or a photoelectric proximity switch, because the movable idler gear 91 maintains contact with the film material T during the process in which the film material T is continuously fed by the take-up reel 11 The movable idler 91 is pulled due to the change in the tension of the film material T. When the tension of the film material T and the traction force of the tractor 92 are balanced, the movable idler 91 stops moving, and therefore, the movable idler 91 is detected by the transmission. The position can be inferred from the tendency of the tension of the film material T to change (large or small).

In practice, at the beginning of the automatic dispensing operation of the raw material roll S, the diameter of the raw material roll S is large, and the release speed of the film material T in the tangential direction of the raw material roll S is large, and the tension of the film material T is higher. In a small case, the force of the tractor 92 pulls the movable idler 91 to a position farther from the discharge reel 11 (see "Fig. 14A"); the automatic cutting and dispensing equipment is used for the material of the reel type film material. During the automatic and continuous winding and cutting operation of the roll S, the diameter of the material roll S is gradually reduced (see "Fig. 14B"), and if the rotation speed of the take-up reel 11 is maintained, the film material T is in the raw material roll. The release speed of the tangential direction of S is gradually reduced. When the rotation speed of the driving roller 13 is constant, the tension of the film material T is gradually increased, and the movable idle gear 91 is pulled to change its position, so dynamic adjustment is required. The rotation speed of the reel 11 prevents the film material T from affecting the winding quality of the film material roll TC in the take-up mechanism 20 due to the change in tension (too large or too small).

According to an embodiment of the present invention, the control unit 50 will be based on the position of the movable idler 91. The rotation speed of the first driving unit 61 is controlled to maintain the film material T between the take-up reel 11 and the driving roller 13 within an appropriate tension range, thereby maintaining the film material T wound up in the winding mechanism 20 into a film material roll. In one embodiment of the present invention, the position detector 93 is a linear variable resistor, and one end of the movable idler 91 is connected to the position detector 93 for interlocking. The linear variable resistor changes its resistance value, detects the position of the movable idler 91 through different resistance values, and further knows the tendency of the tension of the film material T to change, and then controls the first driving unit 61 by the control unit 50. The rotational speed is such that the film material T between the take-up reel 11 and the drive roller 13 is maintained within an appropriate tension range.

In an embodiment of the invention, the tractor 92 is a pneumatic component (such as a pneumatic cylinder or an adjustable damping pneumatic telescopic rod), and the control unit 50 transmits a controllable solenoid valve and a compressed gas supply unit. The traction of the tractor 92 can be adjusted according to actual conditions.

While the present invention has been described above by way of example, the present invention is not intended to limit the invention, and the invention may be modified and modified without departing from the spirit and scope of the invention. The scope of patent protection is subject to the terms of the claims attached to this specification.
