The shaft and the support bracket of the shaft, 74 is the coupling of the main drive shaft.

It will be described in detail according to the driving source of the motor in the operating state of the present invention composed of the above method and apparatus.

First, as shown in FIGS. 1 and 3a and d, the first feeding roll 10 is rotated through the pulleys F ₁ and F ₂ by the driving of the first motor M ₁ , and the upper and lower hangers 11, The film unwound by the film rolls 11R and 12R caught by 12) is superimposed in two layers on the guide roll 13, and passes through the upper guide rolls 14a, 14b and 14c as shown in FIG. The cut line is drilled by the cutter 18K of the point cutter 1 because the cut 18K is always pressurized by the tension spring 18S while maintaining the proper pressure with the guide roll 14b as shown in FIG. to be

Of course, in order to adjust the width of the perforated line, the knob 17N may be loosened, and the shaft 16s may be moved left and right with a guide and tightened to fix it. The two-ply film having a perforated line is unwound and supplied from the film rolls 11R and 12R continuously by the first feeding roll 10, wherein the tension control action of the supply film by the tension adjusting unit 2 is As shown in FIG. 3, the film, which is turned up and down along the guide rails 22 which are elevated along the guide rails 21 on both inner sides of the frame F, is pulled by the second feeding roll 20 which will be described later. As shown above, the guide roll 22 is raised and lowered from the bottom to the top of the die D, and when the operation of the second feeding roll 20 is stopped (when sealed by a thermal cutter), the self-weight of the guide roll 22 The guide roll 22 is lowered again by the action of the first feeding roll 10 and the tension of the feed film is made.

On the other hand, this way, the second motor to be described later based on the detection of a movement pattern detection sensor 37 in a printing a mark on at regular intervals of the pattern if there is a pattern in which enters the film state with a die upper part (M ₂ Stop the transmission of the power by the power transmission by the), the pattern detecting sensor unit 3 rotates the knob 33 as shown in Figs. By moving forward and backward along the rack gear 32, the pattern detection sensor 37 coupled to the guide bar 36 rolled on the guide bracket 35 is moved forward and backward, and the fixed knob 37N can be released to move left and right. Thus, the position can be changed according to the pattern of the supply film.

The film thus supplied is supplied to the thermal cutter 4 by the second feeding roll 20. The action of the film is driven by the driving of the second motor M ₂ as shown in FIGS. 5 and 6a. As the main drive shaft 51S is rotated by rotating the pulley 51F, the ratchet driving wheel 55 is rotated, and the eccentrically coupled arm 55A moves the rack gear 55G forward and backward in a linear motion. It is transmitted to the gear 56G, and the wheel drive shaft 56S is rotated forward and backward. At this time, the proximity switch 57S performs intermittent switching in accordance with the rotation of the cam 57 at the other side of the main drive shaft 51S. By operating the clutch 56C of the shaft 56S, the wheel 56 is driven at the forward rotation, and the drive of the wheel 56 is clutched at the reverse rotation. Therefore, only when the wheel drive shaft 56S rotates forward, the wheel 56 drives the timing pulley 20F by the belt V as shown in Figs. 6d and e so that the pair of upper and lower pairs of second feeding rolls 20 is rotated. At the same time as driving, the conveyor belt driving roll 20R of the bottom surface of the thermal cutter 4 is driven by the idle gear 20G ₁ .

That is, when the drive from the second motor (M ₂ ) is not transmitted by the clutch 56C, the cutting operation of the film supplied with the stopping of the second feeding roll 20 and the conveyor C ₁ is performed. Since the pressurized heat cutting of the heat cutter 4 to be described later is made, and when the driving force is transmitted, the heat cutter 4 discharges the pre-cut packing table while waiting for the next pressurization from the upper conveyor (C _2). It is a state to be transferred to) side.

Referring to the action of the thermal cutter 4 at the time of stopping the second feeding roll 20 and the conveyor C ₁ , the main drive shaft 51S by driving the second motor M ₂ is also shown in FIG. 6A. ) Rotates the first eccentric flywheel 51F ₁ , the first drive link 51L ₁ forward and reverse rotation of the shaft 52S ₁ at a constant stroke angle through the first connecting arm 51A ₁ , this shaft of the opposing side (52S ₂₎ to the shaft (51S ₁₎ the third link second arms (51A ₂₎ provided on both ends (51L ₃₎ the second arm (51A ₂₎ and each shaft (52S as connected by a ₁ , 52S ₂ ) move the same. At this time, the third arm 51A _{3 at} each shaft end is driven to raise or lower the guide rod 42 at the end of the connecting plate 53 (see also FIG. 6B).

At this time, the tension coil (58) connected to the third arm (51A ₃ ) and Daimonche age (see also 6b) serves to give rise to the elastic force after the lowering, sealing of the thermal cutter (4). The lifting action of the thermal cutter 4 by the guide rod 42 is when the guide rod 42 is lowered in the state of FIG. 5 in which the second feeding roll 20 and the conveyor C ₁ are in operation ( The guide plate 42 which penetrates the ring guide metal 41 and guides ascends and descends first, while the press plate 46 having the guide hole 46H is clamped with the inflow film on the stopped conveyor C ₁ , is continued. The compression coil spring 45S between the cutter bracket 45 and the pressing plate 46 is lowered to lower the sealing cutter 47K so as to be horizontally lowered to the bottom of the cutter bracket 45 so that the hole of the pressing plate 46 is lowered. 46H) is inserted into the thermal cutting. At this time, the nut 44N acts to adjust the cutting pressure of the thermal cutter by adjusting the elasticity of the compression coil spring 44S by loosening and tightening thereof. Thereafter, the thermal cutter 4 rises and returns, and simultaneously drives the second filling roll 20 and the conveyor C ₁ .

On the other hand, after the sealing work is finished packaging is discharged by the discharge conveyor (C ₂ ), at this time, in order to prevent obstacles in the inflow of the packaged sealed to the inlet of the discharge conveyor (C ₂ ), that is, for smooth discharge The belt rolling shaft 52S ₃ (see FIG. 7) intermittently expands and contracts, and its action is the second eccentric fryer 51F ₂ coupled to the main drive shaft 51S as shown in FIG. 6A. The second link 51L ₂ in accordance with the rotation of the drive the shaft (52S ₄ ) by interlocking the fourth arm (51A ₄ ) and the shaft (52S ₄ ) is the fifth arm (51A ₅ ) and the fourth link ( By interlocking 51L ₄ ), the arm plate 54 coupled with the pin 54P expands and clamps the belt rolling shaft 52S ₃ located at the inlet side of the discharge conveyor C ₂ . That is, when the second feeding roll 20 and the conveyor C ₁ are in operation, the expansion and expansion of the sealed packing table are good, and when stopped, the gap is moved and discharged (see FIG. 7).

The present invention is constructed and operated as described above by pulling the film in two layers from the compressed film roll of the upper and lower support by the first feeding roll driven by the first motor to cut the point and simultaneously by the second motor drive The guide roll is raised and lowered according to the operation of the 2 feeding rolls to maintain the tension of the feed film, and the flower cutter is formed by sealing two layers of film with a heat cutter when stopping by intermittent transfer. It is a method and a configuration in which the belt rolling shaft at the inlet side of the discharge conveyor is expanded and narrowly conveyed by two motors. It is a very special invention that can be used to supply a large number of flower packs in a growing flower export market at low prices.
