Description

  The present invention relates to an apparatus for quickly cleaning the inside of a cup immediately before filling the food in a line for automatically filling the food in the supplied cup.

Conventionally, as shown in FIG. 6 (a), a line for automatically filling foods into a cup supplied using a rotating drum, and a cup is directly supplied onto a retainer conveyor as shown in FIG. 6 (b). In any of the lines for automatically filling the food, the cups are automatically filled with the supply of the molded cups.
None

  However, during the process of receiving the supply from the molding of the cup, it may go through a transportation process, etc., so that various impurities such as hair and broken pieces of the cup are mixed in the cup even though it is one out of 100. Therefore, when filling the food without washing, although most of the cups are clean, the problem arises that one of the many is contaminated with impurities.

In the present invention , the cups are sucked out one by one on a rotating drum that rotates intermittently from the supply cylinder, and the cup is turned downward by 180 ° rotation so as to cover the food on the drum, and the cup is turned upward by intermittent rotation of the drum. In the automatic filling line of the food material to be sent to the retainer conveyor of the closed lid packaging line, the suction cup is moved to the position just before filling the food material with the opening outside the opening by the 90 degree intermittent rotation of the rotating drum. The cup is provided with a cleaning device comprising an air suction cylinder having a suction opening widened in a trumpet shape and a plurality of air injection nozzles arranged so as to reciprocate in an equidistant range on the outside of the suction port. So that the air spray angle is slightly changed by the reciprocating motion of each air injection nozzle so that no cleaning residue is generated. To, it was so as to solve the problem.

  According to the present invention, since the inside of all supplied cups is washed and then filled with foodstuffs, there is an effect that it is possible to provide a foodstuff filled cup free of impurities. Each cup has a combination of air blowing by an air jet nozzle and air suction by an air suction cylinder, so that it can be washed in two ways, blowing and sucking, from light items such as hair to heavy items such as metal pieces. This produces an effect that the impurities can be surely eliminated from the cup.

  By reciprocating the air injection nozzles in equal sections, the air blowing pressure per injection nozzle can be increased by reducing the number of nozzles, and impurities can be cleaned by slightly changing the air blowing angle due to the reciprocation. The effect of eliminating the remaining is produced.

The present invention is directed to a line for automatically filling food in a cup to be supplied, an air injection nozzle that blows and cleans the inside of the cup at the cup position immediately before filling the food, facing the opening surface of the cup, and an air A cleaning device comprising an air suction cylinder for suction and cleaning was arranged to automatically clean the inside of the cup immediately before filling with food by the cooperation of air blowing and air suction.
By reciprocating the range of the equal division, the air injection nozzle can cover the entire circumference of the cup with a small number such as four. The air suction cylinder is widened to increase the suction range.

  As shown in FIG. 1, the cups C are sucked out one by one from the supply cylinder 1 onto the rotating drum 2 that rotates intermittently, and the food C on the drum 3 is covered with the cup C facing downward by rotating 180 degrees. With the intermittent rotation of the drum 3, the cup C is turned upward and the lid 2 is fed to the retainer conveyor 4, which is a packaging line. The rotating drum 2 is rotated 90 degrees and the cup C is turned sideways with the opening outside. The inside of the cup C is quickly cleaned by bringing the cleaning device 7 of the present invention close to the opening of the cup C at a point, that is, a point immediately before the food S is put on. During this time, the intermittent rotation time is synchronized with the intermittent rotation time, and the intermittent rotation pitch of the drums 2 and 3 does not change. Impurities such as hair that may be contained in the cup C are blown and washed by air injection from the air injection nozzle 5 and then reliably cleaned by suction and cleaning by the inner air suction cylinder 6.

  As shown in FIG. 2, a plurality of air injection nozzles 5 are provided at regular intervals in order to blow and wash the entire inner circumference of the cup C without leaking. Corresponding to the circular shape or quadrangular shape of the cup C, the circular shape or the quadrangular shape is arranged in parallel. The impurities sucked by the air suction cylinder 6 are discharged to a dust collector (not shown) outside the room through the pipe 6a. Next, the cup C is turned downward by the rotary drum 2, covered with the food material S, and sent to the retainer conveyor 4 for packaging.

  The cleaning device 7 for the circular cup C is configured by providing an air suction cylinder 6 having a suction port 6b expanded in a trumpet shape and several to ten or more air injection nozzles 5 at equal intervals on the outer periphery thereof. . The air injection nozzle 5 is disposed so as to inject air from the inner wall of the entire circumference of the cup C toward the bottom surface. 5a is an air conduit connected to an external air compressor (not shown), and 5b is a branch pipe for distributing air entering from the air conduit 5a to each air injection nozzle 5.

  As soon as the cup C rotates 90 degrees and faces the cleaning device 7 and stops intermittently, the cleaning device 7 injects air from the air injection nozzle 5 in close proximity so as to close the outer surface of the opening of the cup C. (FIG. 3). The cup C, which may contain impurities such as hair, should be washed away so that the impurities such as hair are blown away by the blowing pressure of the air and sucked from the air suction tube 6 on the inner side, and the pipe 6a. It will be removed by collecting the dust in the connected external dust collector. By making the air suction by the air suction cylinder 6 and the amount of air blown to be jetted as close to each other as possible, all the blown-off impurities are sucked out by the air suction cylinder 6, so that there are impurities in the surroundings. It will not scatter or pollute the environment. Since dust and the like that are not visible are also eliminated by washing at the same time in the cup C, all the cups C in which no impurities are mixed can be filled with foodstuffs after improving hygiene. When the cups C are supplied in several rows of two or more rows, the cleaning device 7 is provided for each row, and a plurality of cups C arranged side by side are washed simultaneously.

  FIG. 2 (c) shows a washing device for the cup C having a quadrangular shape. The air injection nozzles 5 are arranged in parallel in a square frame shape in accordance with the quadrangular shape of the cup C, and the opening of the air suction cylinder 6 is opened. Except for the square cup, it is the same as for the round cup.

  As shown in FIG. 4, in the line for supplying the cup C directly to the retainer conveyor 4, the cleaning device 7 of the present invention is provided on the section immediately before the food filling portion 8 in the downward direction, and the upward cup C that comes and goes. Clean it close to the surface. The cleaning procedure is the same as the previous example.

  By rotating the air injection nozzle 5 back and forth in a certain section, the entire circumference of the cup C can be covered with a small number. FIG. 5 shows an example in which four air injection nozzles 5 are provided at intervals of 90 degrees. By reducing the number of air injection nozzles 5, the wind pressure per nozzle is increased in inverse proportion to the number of the air injection nozzles 5, thereby improving the blowing and cleaning performance. In addition, since the air spray nozzle 5 is reciprocally rotated by means such as a servo motor (not shown) together with the cleaning device, the air blowing angle with respect to the impurities is changed, so that the adhered impurities are also blown away and cleaned. Will be. The number of nozzles can be set to 3 for rotational reciprocation at 120 degrees, or 6 for 60 degrees rotational reciprocation.

  As described above, the present invention can be widely used as a device for cleaning the inside of a cup immediately before food is automatically filled, regardless of the size or shape of the cup.
