Description

Pillow Automatic Packing Machine

The present invention relates to a pillow automatic packing machine, and more particularly to a pillow automatic packing machine of a new structure that can easily automatically correct the transfer speed of the packaging film according to the packaging state.

The pillow packing machine is a device for automatically wrapping a packaged object in a film bag, that is, a pillow. Such a device includes an attachment conveyor for sequentially supplying a packaged object, a film supply mechanism for taking out a film wound on a film supply roll, a former for folding the supplied film to surround the transported object, and a center portion of the film surrounded by the packaged object. A center sealing mechanism, and a sealing cutting mechanism for cutting the front and rear ends of the package simultaneously with sealing. Such a pillow packaging machine is not packed properly because the film is expanded, broken or stretched if the line speed of the supplied film does not match the operating cycle of the sealing or cutting tool. Moreover, since various patterns or trademarks are printed on the packaging film, if the feeding speed of the film and the sealing or cutting position are not exactly the same, the printing part of the wrapping paper may be out of position or the airtightness of the packaging may not be maintained after the packaging is completed. May be generated.

Therefore, the film supply mechanism, the sealing mechanism, the cutting mechanism, etc. are configured to be synchronously operated by being connected by a chain or gear. However, due to the stretching of the film due to the material or temperature of the film, or other reasons, the linear velocity of the film and the timing of the sealing and the cutting tool do not coincide, which causes unavoidable packaging or entanglement of the film.

The present invention has been proposed in view of the problems of the conventional pillow packer as described above, if for some reason the feed rate of the packaging film does not match the sealing or cutting timing, automatically detect and correct it, and withdraw the center sealing portion It is an object of the present invention to provide a pillow automatic packaging machine having a new structure that can easily correct film transfer errors such as sagging of a film between a roll and a center sealing roll by manual operation.

Hereinafter, with reference to the drawings will be described a preferred embodiment of the present invention. 1 is a front view of the packaging machine of the present invention, and FIGS. 2 to 4 are schematic plan views, side cross-sectional and front sectional views of the drive mechanism of the device according to the present invention.

As shown, according to the present invention, the feed roll 10 is provided in the form of a roll of the film (P) marked marking at regular intervals to indicate a predetermined ad text or product name and the lateral cut of the film, and the film It includes a printing machine 11 for printing the date (P), the film P passed through the printing machine 11 is supplied to the former 22 through a pair of feed roll 12 and the tension roll (13). On the film transfer path of the rear end of the printing machine 11, the first sensor 14 is provided to be adjustable in position on the post 15. The sensor 14 detects the marking marked on the film P and adjusts it to synchronize the feeding speed, sealing and cutting of the film together with the second sensor 39 described later.

On the other hand, in front of the former 22, an attachment supply conveyor 20 for sequentially supplying the packaged object 21 is installed, and the packaged object 21 transferred by the supply conveyor 20 is a former 22. It is put into the inside. The former 22 is formed in a downwardly open channel shape to fold both ends of the film P to be introduced to form a bag to surround the package 21. A pair of left and right take-out rolls 34 is disposed at the rear end of the former 22. The takeout roll 34 advances the overlapping portion in the longitudinal center of the bag-shaped film P containing the package 21 by frictional contact, and the left and right pairs of center sealing rolls 36 are arranged next to each other. The center overlap is heated to seal it. In this way, the bag-shaped film P sealed in the center portion is made up of a pair of rolls arranged up and down again and is simultaneously cut in the transverse direction while being cut through the sealing cutter portion 40 in which the cutter is formed and separated into individual packages. . In this way, the finished product is discharged on the discharge conveyor (23). A second sensor 39 is installed in the sealing cutter unit 40 to detect that the marking marked on the wrapping paper passes. Referring to FIGS. 2 to 5, the drive mechanism 50 of the present invention will be described. First, an output shaft of the drive motor 51 made of a gear motor is provided with a belt transmission 52 having an adjustment handle 53. do. The belt transmission 52 appropriately shifts the rotational speed of the drive motor 51 by adjusting the relative effective diameters of the pulley 54 and the pulley 55 with the handle 53. As shown in FIG. 4, the drive shaft 58 is coupled to the rear pulley 55 of the belt transmission 52, and the other side of the drive shaft 58 has a conventional gear 62 composed of different gear ratios. And the gear 60 to which the electromagnetic clutch 61 is attached are axially coupled. These gears 60 and 62 are coupled to the gear 65 and the gear 66 with one-way clutch bearing 64 by the chain 67, respectively, and the gear ratios of these gears 65 and 66 are the same. These gears 65, 66 and another gear 68 adjacent thereto are coupled to the driven shaft 70.

The bevel gear mechanism 71 is condensed on the driven shaft 70 to rotate the take-out roll 34 through the drive shaft 81. The gear 84 coupled to the drive shaft 81 is meshed with the gears 85 and 86 of the driven shaft 82 through the first connecting gear 87 or the second connecting gear 88. 82 rotates the center sealing roll 36. The first connection gear 87 and the second connection gear 88 are made of different gear ratios, and the gear ratios of the gears 85 and 86 are the same. The chain 68 is connected to the gear 68 to drive the aforementioned feed roll 12. On the other hand, a separate chain 69 is directly connected to the drive motor 51 to drive the roll of the sealing cutter unit 40 described above.

Referring to the operation according to this configuration, the driving force of the drive motor 51 is transmitted to the driven shaft 70 through the gear 62 and the gear 66 through the drive shaft 58, the driven shaft 70 is The feed roll 12 is rotated through the gear 68 while rotating the take-out roll 34 and the center sealing roll 36 through the bevel gear mechanism 71. Therefore, the linear speed of the film P supplied through the feed roll 12 and the rotational speed of the take-out roll 34 and the center sealing roll 36 are maintained substantially constant. However, the sealing cutter portion 40 driven by the chain 69 directly connected to the drive motor 51 is the cutting and packaging of the packaging while rotating at a set speed through the input means of the controller 100 according to the package and the packaging specifications. Sealing is performed.

In the normal operation state, the timing of detection of the marking on the film of the first sensor 14 provided on the film transfer path and the second sensor 39 provided on the cutter sealing portion 40 is substantially coincident. However, for some reason, for example, due to the material, thickness, or temperature difference of the packaging film P, the feeding speed of the film does not coincide with the operating cycle of the sealing cutter portion 40, and thus, when detecting the marking of the first sensor 14. If the marking is not detected by the second sensor 39, the controller 100 determines this and operates the electronic clutch 61 installed on the driving shaft 48. Then, in addition to the power transmission through the gear 62 and the gear 66, the electromagnetic clutch 61 is frictionally connected, and power is also transmitted to the gear 65 of the driven shaft 70 through the gear 60. At this time, since the teeth of the gear 60 is greater than the teeth of the gear 65 and the teeth of the gears 62, 65 and 66 are the same, the gear 65 rotates faster than the gear 66, and thus the one-way clutch The gear 66 in which the bearing 64 is attached is turned to block the power transmission therethrough. Therefore, the driven shaft 70 rotates relatively quickly, and the rotational speeds of the take-out roll 34 and the center sealing roll 36 and the feed roll 12 which are operatively connected thereto are also increased. In this way, when the linear velocity of the film is increased so that the marking detection timing of the first sensor 14 and the detection timing of the second sensor 39 of the sealing cutter unit 40 are matched again, the electronic clutch 61 of the electronic clutch 61 is controlled by the controller 100. The operation is stopped and the correction is completed by matching the film feed rate with the operation timing of the sealing cutter unit 40.

On the other hand, as shown in FIG. 5, in the normal state, the driving force of the drive shaft 81 transmitted through the bevel gear mechanism 71 directly rotates the take-out roll 34 and simultaneously the gear 84 and the first connecting gear. The center sealing roll 36 is rotated through the driven shaft 82 through the 87 and the gear 85. Therefore, the rotation speeds of the take-out roll 34 and the center sealing roll 36 are the same. By the way, there arises a case where the speed of the film P drawn out through the take-out roll 34 does not coincide with the speed of the sealing treatment in the center sealing roll 36 due to the difference in the elongation of the film or the slip of the film. Then, the film between the lead stone 34 and the center sealing roll 36 is stretched so that the center sealing is not made correctly and the airtightness of the packaging may be damaged. In this case, the screw shaft 91 is raised by adjusting the handle 80 shown in FIG. Then, the spring 89 mounted on the upper end of the screw shaft 91 raises the second connecting gear 88, and at this time, the first connecting gear 87 and the second connecting gear 88 through the friction plate 83. Is drivingly connected. However, since the second coupling gear 88 has a larger gear ratio than the first coupling gear 87, the rotational speed of the gear 85 meshed with the first coupling gear 87 is increased by the second coupling gear 88. Is slower than the rotational speed of the gear 86 engaged with the gear. Therefore, the driven shaft 82 is rotated through the gear 86 having a high rotational speed by the clutch bearing 90 so that the speed of the center sealing roller 36 is increased so that the normal film is made by unfolding the stretched film P. do.

According to the present invention described above, the sensor is installed in the film transfer path and the sealing cutter of the pillow packaging machine, if the linear velocity of the film and the sealing and cutting timing is inconsistent, it is detected by the electronic clutch mechanism to automatically drive the drive mechanism By increasing the speed, the linear velocity of the film is corrected, and if the film is stretched between the take-out roll and the center sealing roll, the relative rotational speed of the center sealing roll is increased by manual operation, so that the difference in the thickness or material of the packaging film or The pillow automatic packaging machine of the new structure which can easily and automatically correct the quantity of packaging due to the difference of temperature will be provided.
