Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a PET bottle filling and capping device,

The present invention relates to a PET bottle filling and capping device that automatically transfers a hollow PET bottle, and after filling the beverage inside the PET bottle and then sealing the opening of the PET bottle with the cap.

PET (polyethylene terephthalate) is a bottle made of polyethylene. It is light, does not break easily and can be recycled. It is widely used as container for drinking water and water.

Most beverage companies are equipped with PET bottle filling and capping devices to manufacture beverages as well as to contain and seal manufactured beverages in PET bottles.

Under mass production, each functional part is mounted on a conveyor line while transferring a hollow PET bottle onto a large scale conveyor line. For example, the functional unit may be a cap filling unit for capping a beverage filling unit for filling a beverage with a hollow PET bottle, a cap supply unit for capping and supplying a cap to an entrance of a PET bottle filled with beverage, and a capping unit for sealing the cap by rotating the cap at the entrance of the capped PET bottle. The beverage charging section, the cap supply section, and the capping section are sequentially installed on the conveyor line in a large size.

That is, a large amount of PET bottles are transferred at once, and a large amount of PET bottles are charged at a time in a beverage charging unit, and the cap supply unit supplies cap bottles to each of a large number of PET bottles at a time. The capping unit also caps a large number of PET bottles at one time And is rotated and sealed. This is because, under mass production conditions, it is not surprising that bottles are charged and capped one by one in small quantities, which reduces productivity.

However, it is difficult for small companies to use large-sized PET bottle filling and capping devices used by beverage makers. For example, in the case of a vendor that sells and sells the syrupy sap and a honeypot farmer who operates a honey farm, it is difficult to buy a large-scale PET bottle filling and capping device as well as to purchase it.

In this regard, there is a need to develop a small-sized PET bottle charging and capping device which can be easily and easily used by small-sized vendors. However, if each of the above-described functional units is installed on the conveyor line, the first line becomes long and the whole apparatus becomes large. In addition, since the operation intervals of the second functional units are different from each other, Resulting in decreased productivity. Third, there arises a problem that it is difficult to adjust the intermittent transportation cycle of the PET bottle so that each functional part installed on the straight line conveyor line can operate on the PET bottles being transported.

Therefore, instead of arranging the respective functional portions on a conveyor line in a line, the conveyor is divided into an inlet conveyor and an outlet conveyor, and a PET bottle rotating wheel capable of rotating the PET bottle between the inlet conveyor and the outlet conveyor is installed, The respective function units can be provided in a radial sequence above the wheel. This is because the PET bottle wheel is easy to rotate the PET bottles intermittently through angle division, so it is easier to fit the PET bottle intermittent transfer cycle than to arrange each function section in line on the straight line conveyor line.

However, as a driving unit for intermittent rotation transfer of a conventional PET bottle rotary wheel, it is inevitable to construct a complicated gear combination for a rotary motor, or to use expensive equipment such as an index table or a complicated configuration. Since each function unit can not be installed together, There arises a problem that the apparatus is inevitably equipped with a rotary wheel and the production cost is increased. This is because the operation interval of the beverage charging section in the functional section is much longer than the operation interval of the capping section or the capping section which is the other functional section. That is, since the beverage charging unit needs to be charged according to the predetermined amount of beverage, that is, a predetermined amount, when filling the beverage into the inside of the PET bottle, the initial rapid charging and the latter constant amount charging are performed through one nozzle. In more detail, the operation interval of the cap supply unit or the capping unit is about 2 seconds, but the operation interval of the beverage charging unit is required to be at least 5 seconds to 6 seconds.

In summary, the conventional PET bottle filling and capping apparatus has a problem that the configuration of the rotation driving unit for intermittent rotation transfer of the PET bottle rotary wheel is complicated and expensive equipment is used, and the second is that the respective functional units are installed together on the single PET bottle rotary wheel .

SUMMARY OF THE INVENTION It is an object of the present invention, which is conceived from the above-described viewpoints, to provide a simple structure of a rotary drive unit for intermittent rotation of a PET bottle rotary wheel through a combination of low-cost mechanisms, To reduce the size of the entire device, and to provide a low-cost PET bottle filling and capping device that is easy to use by small businesses.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 to 14, the PET bottle filling and capping apparatus according to the present invention includes an inlet conveyor 100, a PET bottle rotating wheel 200, a rotation driving unit 300, a beverage charging unit 400, a cap supplying unit 500, A capping unit 600 and an outlet conveyor 700. The rotation driving unit 300 includes a rotating shaft 310, a Geneva driven wheel 320, a Geneva driving wheel 330, and a rotating motor 340 . The beverage charging unit 400 may include a charging body 410, a first rapid charging nozzle 420, a second rapid charging nozzle 430, and a third rapid charging nozzle 440.

The inlet conveyor 100 conveys a hollow PET bottle PB formed with a neck flange PBa sequentially, as shown in Figs. 1 to 3, and operates as an endless track. A PET bottle (PB) is a bottle made of a general polyethylene material and is composed of a body containing a shoulder and a drink under the shoulder, which is expanded from an inlet (PBb) and an inlet (PBb) A neck flange PBa annularly protruded between an inlet PBb and a shoulder of the main body is formed. These PET bottles PB are sequentially conveyed through the inlet conveyor 100 in a hollow state.

As shown in FIGS. 1 to 3, the PET bottle rotary wheel 200 is installed at the rear of the inlet conveyor 100, and has a plurality of gripping grooves 210 formed at regular intervals along the outer circumference of a disk- The PET bottle PB is transferred from the inlet conveyor 100 to the gripping groove 210 so that the neck flange PBa of the PET bottle PB is caught. The PET bottle rotary wheel 200 rotates intermittently with reference to the rotation center of the disc shape through the rotation drive unit 300 to be described later and grips the PET bottle PB through the gripping groove 210 formed around the outer periphery. That is, the neck of the PET bottle PB is inserted into the grip groove 210, the neck flange PBa is caught in the grip groove 210, and the PET bottle PB caught in the grip groove 210 is engaged with the PET bottle rotation wheel 200 It is rotated intermittently with rotation.

The rotation driving unit 300 intermittently rotates the PET bottle rotary wheel 200 as shown in FIGS. More specifically, the rotation drive unit 300 includes a rotation shaft 310, a Geneva driven wheel 320, a Geneva drive wheel 330, and a rotation motor 340. The upper end of the rotary shaft 310 is fixedly coupled to the rotation center of the PET bottle rotary wheel 200, and the lower end of the rotary shaft 310 extends downward. In addition, the Geneva driving wheel 320 has a rotation center fixedly coupled to a lower end of the rotary shaft 310, and a plurality of radial driving grooves 321 are formed around the outer periphery. That is, the upper end of the rotary shaft 310 is fixedly coupled to the PET bottle rotary wheel 200 and the lower end thereof is fixedly coupled to the Geneva driven wheel 320. Thus, the rotary shaft 310, the PET bottle rotary wheel 200 and the Geneva driven wheel 320, Is a structure that rotates together when any one of them rotates. In this case, the Geneva drive wheel 330 is installed to be rotatable adjacent to the Geneva driven wheel 320, and a single drive pin 331 protruding from the rotation center is provided to the drive groove of the Geneva drive wheel 320, (321) to intermittently rotate the Geneva driven wheel (320). That is, the Geneva driven wheel 320 and Geneva drive wheel 330 are Geneva mechanisms which are intermittent rotating mechanisms by the mutual drive grooves 321 and the drive pins 331. [ The rotation motor 340 rotates the Geneva drive wheel 330 in a predetermined direction. The driving pin 331 is rotated and the driving pin 331 is inserted into the driving groove 321 of the Geneva driven wheel 320 The intermittent movement of the Geneva driven wheel 320 by the repetitive operation of rotating the Geneva driven wheel 320 and then being inserted into the drive groove 321 of the Geneva driven wheel 320 and then rotating the Geneva driven wheel 320 Rotation is achieved. The intermittent rotation of the Geneva driven wheel 320 leads to the intermittent rotation of the rotary shaft 310 and the PET bottle rotary wheel 200 and the PET bottle PB held in the grip groove 210 of the PET bottle rotary wheel 200 is intermittently rotated .

The PET bottle gripped by the PET bottle rotation wheel 200 is intermittently rotated through the PET bottle rotation wheel 200 and the rotation drive unit 300 so that the PET bottle PB repeats the rotation transfer and stop operations. At this time, when the stopping operation of the PET bottle PB is performed, each of the functional units described below sequentially performs respective functions for the PET bottle PB. That is, the beverage charging part 400 charges the beverage in the inside of the PET bottle PB, the cap supplying part 500 supplies the cap PB to the inlet PBb of the PET bottle PB and supplies the cap C to the capping part 600, Is to seal the cap (C) on the PET bottle (PB).

1 and 6, the beverage filling part 400 is installed above the PET bottle rotary wheel 200, and the PET bottles (not shown) PB through the inlet (PBb) of the beverage. In this case, considering the intermittent operation interval of the PET bottle rotary wheel 200, the beverage charging unit 400 may include a charging body 410 to be filled with beverage, Three first fast filling nozzles 420, a second fast filling nozzle 430 and a quantitative filling nozzle 440 that fill the beverage through the inlet PBb of the first pump PB. Each of the first rapid filling nozzle 420, the second rapid filling nozzle 430 and the fixed amount filling nozzle 440 projects in a direction of rotation of the PET bottle rotary wheel 200, And the first rapid filling nozzle 420 charges 35% to 45% of the total amount of the beverage filling through the inlet PBb of the PET bottle PB, 35% to 45% of the total amount of the beverage filling is further charged through the inlet PBb of the PET bottle filled with the first rapid filling nozzle 420, and the quantitative filling nozzle 440 further charges the PET bottle PB, the remainder after being charged by the first rapid charging nozzle 420 and the second rapid charging nozzle 430 is charged to a predetermined amount (100%).

The reason for separating the beverage charging part 400 from the three nozzles is that when filling a full amount (100%) of the inside of the PET bottle PB with one nozzle, the beverage charging time becomes long, It does not fit the intermittent rotation feed interval. Therefore, in order to match the intermittent rotation transfer interval of the PET bottle rotary wheel 200, the nozzles of the beverage charger 400 are connected to the first rapid charging nozzle 420, the second rapid charging nozzle 430 and the fixed charging nozzle 440 Respectively. At this time, the first rapid filling nozzle 420 and the second rapid filling nozzle 430 quickly charge the beverage into the PET bottle PB by a predetermined capacity, ) Is filled with a predetermined amount of beverage to be charged. Therefore, the first fast filling nozzle 420 and the second fast filling nozzle 430 are charged in a ratio of about 70% to about 90% of the fixed amount, and the remaining 10% to 30% The respective charging times can be separated and fitted to the intermittent rotation transfer interval of the PET bottle rotary wheel 200. [

7, the cap supply unit 500 and the capping unit 600 are provided above the PET bottle rotary wheel 200, and the cap supply unit 500 and the capping unit 600 are disposed above the PET bottle rotation wheel 200, The cap C is supplied to the inlet PBb of the PET bottle filled with the beverage through the charger 400 and supplied. 8, the capping unit 600 is installed above the PET bottle rotation wheel 200 and is connected to the inlet PB of the PET bottle covered with the cap C through the cap supply unit 500 The cap C is rotated and sealed.

The outlet conveyor 700 is a conveyor belt driven in the same infinite track as the inlet conveyor 100. The outlet conveyor 700 is installed at the rear side of the PET bottle rotary wheel 200. After the beverage is filled, The sealed PET bottles (PB) are transferred from the PET bottle rotary wheel (200) and transferred sequentially. The outlet conveyor 700 passes the filled and capped PET bottles PB from the PET bottle rotary wheel 200 to the packaging conveyor 700 for conveying the PET bottles PB to the PET bottle rotary wheel 200. In contrast to the case where the inlet conveyor 100 conveys the hollow PET bottles PB to the PET bottle rotary wheel 200, To the outside.

The beverage charging unit 400, the cap supplying unit 500, and the capping unit 600, which are functional units, should be installed in order along the rotational direction of the PET bottle rotary wheel 200 in terms of their functions. That is, after the beverage is filled in the hollow plastic bottle PB through the beverage charging unit 400, the cap C is covered and supplied to the inlet PBb of the beverage bottle PB through the cap supply unit 500, The cap C of the PET bottle PB capped by the cap C must be rotated and sealed in the capping unit 600. [

10, a hollow PET bottle PB is fed through the inlet conveyor 100, and the neck flange PBa of the PET bottle PB is gripped by the gripping groove 210 of the PET bottle rotating wheel 200 . The PET bottle gripped by the gripping groove 210 is intermittently rotated by the intermittent rotation operation of the PET bottle rotating wheel 200 by driving the rotation driving unit 300. [ The PET bottles (PB) to be rotated are brought into contact with the first drink filling part (400) in the rotating direction of the PET bottle rotating wheel (200).

10 and 11, the beverage charging unit 400 includes a first rapid charging nozzle 420, a second rapid charging nozzle 430, and a fixed-amount charging nozzle 440 sequentially arranged in the rotating direction, The hollow PET bottle PB is filled with 35% to 45% of the beverage by the first rapid filling nozzle 420 and then rotated so that 35% to 45% of the beverage is supplied from the second rapid filling nozzle 430 And is rotated again, so that the remaining beverage is charged in a fixed amount in accordance with a predetermined amount in the fixed-amount charging nozzle 440.

As shown in FIG. 12, the PET bottle filled with a predetermined amount of beverage is continuously rotated while being caught by the holding groove 210 of the PET bottle rotating wheel 200, and then comes into contact with the cap supply part 500 for the second time. The cap C is put on the inlet PBb of the PET bottle PB through the cap 500.

13, the PET bottle covered with the cap C meets the capping unit 600 for a third while being rotated by the PET bottle wheel 200, and the cap C ) Is rotated to seal the inlet PBb of the PET bottle PB. This completes filling and capping of the PET bottle (PB).

As shown in FIG. 14, the filled and capped PET bottles (PB) are transferred from the PET bottle wheel 200 to the outlet conveyor 700, transferred to the outside, packaged, and the PET bottle filling and capping operation is completed. The filling and capping operations for the one PET bottle (PB) are sequentially performed for each of the other PET bottles (PB), thereby filling and capping the large number of PET bottles (PB).
