Description

[Detailed description of the invention] The present invention relates to a paper container processing device.

Paper containers are being used for a wide range of purposes, including milk, juice, and recently sake.

However, conventionally, the production line for paper containers filled with drinking water usually includes a box assembly device that roughly roughens the paper containers by folding flat carton blanks, and a box assembly device that receives the assembled paper containers using this box assembly device. , a filling device for filling the paper container with the milk, fruit juice, etc., and a sealing device provided on the discharge side of the filling device, either integrally or separately, to seal the opening of the paper container filled with drinking water. Equipped with equipment. Such a production line is naturally set up in a clean room to ensure sufficient hygiene, but it is more desirable to assemble the paper containers and before filling them with drinking water. should be washed with liquid. Therefore, the present invention provides a paper container processing apparatus suitable for use in such a production line.

The invention will now be described with reference to the illustrated embodiments.

In FIG. 1, A is a box assembly device, B is a polishing device, and C is a filling device. The above-mentioned box assembly device A is equipped with a first half (not shown), in which a carton blank of a paper container unfolded in one plane is folded in parallel at four points, and then both sides are glued to close the ends. It forms a cylindrical container. This cylindrical container is delivered to the holder 1 of the box assembly apparatus A at the position A in FIG. The vertical rotation shaft 2 includes six holders 1 in a horizontal plane, and each holder is arranged at equal intervals in the radial direction around the vertical rotation shaft 2. This vertical rotation axis 2 is connected to each holder 1.
is rotated intermittently by 60 degrees in the direction of the arrow in FIG. The above-mentioned cylindrical shape with both ends closed is delivered to the holder 1 at the position A, and the holder 1 holds the cylindrical container in a relatively iron-fitted manner within the cylindrical container.

Next, this cylindrical paper container 3 is rotated 60 degrees and positioned at the opening, and is folded by a conventionally known curling mechanism 4 so that the radially outward opening can close the opening. It will be done. The paper container 3 that has been further rotated by 60 degrees is heated by the heating device 5 at the position C, and then bent again by the press device 6 by the above-mentioned curl folding mechanism 4 at the second position where it is rotated by 60 degrees. Can be bent. As is well known in the art, the surface of a paper container is coated with a thermoplastic resin coating for the purpose of waterproofing, etc., so the heating and subsequent bending cause the radially outward sealing part to close to the sealing part. It will be glued in the closed state.

The paper container 3 is thus closed at one end, i.e. at the bottom.
The wood is cooled at the next 60 degrees advanced position of the tree, and further rotated 60 degrees to reach the delivery position to the vertical washing device 8. This type of string box device A is already known in the art. The refining device B is equipped with a horizontal rotating shaft 7 and a disc 8 attached to the tip of this shaft in a vertical plane. , six holders 9 are provided at equal intervals in the radial direction of the disk 8.

As shown in FIGS. 3 to 5, each holder 9 includes a pair of cases 10 and 11 each having a U-shaped cross section, and a rectangular connecting plate 12 that connects both cases 10 and 11 with the cases 10 and 11 facing each other with a predetermined distance L between them. The paper container 3 can be stored between the pair of cases 10 and 11. A mounting plate 13 having a U-shaped cross section is connected and fixed to the outer periphery of the case 10, a bracket 14 is fixed to the outer periphery of the disc 8, and a pin 15 press-fitted into the mounting plate 13 is formed on the bracket 14. screw 1 while engaged in the hole 16
The holder 9 is attached to the disc 8 by attaching the attachment plate 13 to the bracket 14 by means 7. moreover,
One case 11 constituting the holder 9 has a window 18 at a predetermined position, and a leaf spring 19 attached to the case 11 is made to protrude from the window 18 into the pair of cases 10 and 11. The paper container 3 inserted into the holder 9 can be held by the holder 19. Further, the connecting plate 12 is provided with a notch 12a so as to correspond to the distance L formed between the two cases 10 and 11, and the claws of the paper container retainer and ejecting device described below are attached to the connecting plate 12. I try not to interfere. Note that the holder 1 is also provided with a clearance for the claw. When the holder 1 of the assembled box apparatus A stops at the delivery position and the holder 9 of the refining apparatus B stops in a straight line above the holder 1, the paper container feeding and discharging apparatus D It has a function of simultaneously carrying out the operation of concentrating the paper container 3 from the holder 1 into the holder 9, and the operation of discharging the paper container 3 that has been washed with rice bran from the holder 9, which is 180 degrees out of phase with the holder 9. are doing.

As shown in FIGS. 1 and 2, this device D is a reciprocating motor which is supported so as to be able to reciprocate in the horizontal direction from a pair of brackets 9 on the sides of a pair of holders 9 that are 180 degrees out of phase. It is equipped with 21. A guide punch 22 is arranged and fixed between the pair of brackets 20 in parallel with the reciprocating shaft 21, and a connecting member 23 is slidably provided with respect to the guide shaft 22.
is fixed approximately at the center of the reciprocating punch 21, and the reciprocating punch 21
The cylinder device 24 arranged parallel to the connecting member 23
is connected to. At both ends of the reciprocating village 21, claw mechanisms 25 and 26 which can be engaged with the paper container 3 are provided, respectively.
Since both claw mechanisms are formed substantially the same, one claw mechanism will be explained. As shown in FIG.
7 is attached, and claws 28 and 29 are provided at the upper and lower positions of the tip of the bracket 27, respectively. This pair of claws 28,2
9, as shown in FIG. 7, are each rotatable around the bottle 30, and normally the upper pawl 28 comes into contact with the stopper pin 31' to restrict clockwise rotation as shown in FIG. The lower claw 29 contacts the stopper pin 32 and is restricted from rotating counterclockwise. In this state, each claw 28, 29 is spaced L apart from the top and bottom of the holder 9.
It is provided so that it can protrude into the holder 9, in other words, it can interfere with the paper container 3, and in the right stroke in FIGS. 1, 2, and 7 of the reciprocating stroke of the reciprocating village 21. are the claws 28 and 2 formed by the stopper pins 31 and 32.
By controlling the rotation of the paper container 9, the engagement state with the paper container 3 is maintained and the paper container 3 is moved, and when moving to the left, the claws 28 and 29 can be freely rotated to disengage the paper container 3. There is. Therefore, as shown in the second diagram, when the paper container 3 is positioned at the delivery position of the string box device A and stopped, the claw mechanisms 25 and 26 located at the right end are moved to the left by the cylinder device 24. row and is located at the left row end position.

In addition, at this time, even if the claws 28 and 29 of each claw mechanism 25 and 26 interfere with the paper container 3, it will not be moved. When each claw mechanism 25, 26 is located at the left end, each holder 9 is intermittently rotated by 60 degrees in the direction of the arrow in FIG. 2 from the horizontal rotation shaft 7, and the empty holder 9 is moved to the delivery position At the same time, the holder 9, which holds the paper container that has been thoroughly washed as will be described later, is positioned at the ejection position shown in FIG. 2. Then, the claw mechanisms 25, 26 are moved to the right by the cylinder device 24, and at this time, the claws 28, 29 of each claw mechanism 25, 26 engage with the paper container 3 and transport it. That is, the claw mechanism 25 moves the paper container 3 held in the holder 1 into the holder 9 so that its opening is radially outward of the disc 8, and
This paper container 3 is held within the holder 9 by the leaf spring 19. At this time, as shown in FIG. 4, for example, l00
The bottom part 3a of the paper container for 0 secretion is pushed in to the vicinity of the connecting plate 12, whereas the bottom part 3b of the paper container for 500' is pushed in only about half way. However, it is desirable to provide it in a position where the paper container 3 can be held. On the other hand, the other claw mechanism 20 pushes out the washed paper container 3 from inside the holder 9 and supplies the paper container 3 to the next filling device C. When the claw mechanisms 25 and 26 reach the right-hand end, the box assembly device A supplies the subsequent paper container 3 to the above-mentioned delivery position, and the above-described operation is repeated thereafter. Therefore, the washing device B is equipped with a washing liquid spray nozzle 33 at a stop position 60 degrees from the position where the holder 9 faces the delivery position, and a washing liquid spray nozzle 33 is provided at a stop position 60 degrees further advanced than the stop position 160 degrees from the position where the holder 9 faces the delivery position. An air nozzle 34 for spraying drying air is provided.

Both nozzles 33 and 34 are each inserted into the paper container 3 held by the holder 9, but since their drive mechanisms are substantially the same, only the drive mechanism of the rice bran spray nozzle 33 will be described. do. The washing liquid spray nozzle 33 is arranged so as to coincide with the axial direction of the paper container 3 located at the stop position, and is slidably provided on a guide 35 and a guide punch 36 parallel to the above-mentioned/zuru 33. The sliding member 37 allows movement in the axial direction.

Links 38 and 39 are connected to the sliding member 37, and a cylinder device 41 which is pivotally supported by a fixed member 40' is interlocked with the link 39, and the cylinder device 41 can operate the /zzle 33. I'm trying to make it possible. This cylinder device 41 is disposed in a chamber 43 separated as much as possible from the chamber 42 in which the nozzle 33 is disposed, so that it is not affected by the refining water. Further, a partition plate 44 is provided on the disc 8 to partition each holder 9, and a cover 45 is provided at the tip of the nozzle 33 to cover that part and allow the relative alignment of the holders 9. Splashing of rice bran water to other parts is minimized as much as possible. Therefore, while the holder 9 is rotating, the nozzle 33 is located at a lowered position where it does not interfere with it, and when the holder 9 stops at the above-mentioned stop position, the nozzle 33 is raised by the cylinder device 41, and the tip of the nozzle 33 is Holder 9
The container 3 is inserted into the paper container 3 held at the container 3.

Then, the inside of the paper container 3 is washed with the washing liquid sprayed from the nozzle 33 continuously or when the nozzle 33 rises, and the holder 9 is placed at a lowered position where it does not interfere with the holder 9 until it is rotated again. It has been restored. 6 more
The air nozzle 34 installed at the stop position after advancing 0 degrees also
It is raised and lowered by the same mechanism as the rice bran spray nozzle 33,
The washing liquid inside the paper container 3 is blown away.

The paper container 3 that has been washed in this manner is transferred directly to the ejection position and ejected from the holder 9 by the claw mechanism 26.

At this ejection position, the holder 9 is placed with the entrance section facing forward.
An attitude control device is provided which receives the paper container 3 pushed out from the container, controls the attitude of the paper container 3 into an upright state, and supplies it to the filling device C. As shown in FIG. 2, this device includes a receiving member 46 having a U-shaped cross section that can receive the paper container 3 pushed out from the holder 9, and a receiving member 46 that is rotated 90 degrees counterclockwise around a shaft 47. The silisodar device 4 rotates in the direction
8, and a chute 49 having a U-shaped cross section. Therefore, the paper container 3 pushed out from the holder 9 is received by the receiving member 46, and when this receiving member 46 is then spread by the cylinder device 48, the paper container 3 on the receiving member 46 is placed at its bottom. falls down on the receiving member 46, is caught by the chute 49, and further
It falls along 0' and stops in an upright position with the entrance facing upward. A transfer device is provided at the stop position in this upright state to intermittently transfer the paper container into the filling device C, and the paper container 3 is filled with drinking water in the filling device C. After that, it will be sealed.

Since such devices are well known in the art, their description will be omitted. Further, in the embodiment described above, the cleaning mechanism is composed of the refining liquid spray nozzle 33 and the E-A nozzle 34, but either one of the two nozzles or another device, such as a sterilizing device using ultraviolet rays, may be used as the rice bran cleaning mechanism. can. As described above, the present invention includes a silk box device for forming a cylindrical paper container with a sealed bottom, a refining device for receiving and holding the formed paper container, and refining or sterilizing it. The washing device is equipped with a filling and sealing device that receives a purified paper container, fills it with liquid, and then seals it. and a paper container feeding position where the tip of the first holder is stopped facing the bottom of the tip of the paper container supported at the forming end position of the assembled box device, and diametrically opposed to the second holder. It is provided so as to be able to slide back and forth along these holders between the paper container discharging position where other holders are located, and the paper containers of the assembly box device are moved to the above-mentioned one by means of claw mechanisms provided at both ends of the sliding section. a supply/discharge device for pushing the paper container into the holder and discharging the paper container in the other holder toward the filling device; The pawl mechanism is provided in the protruding position when the paper container is moved along the moving direction of the paper container, and is provided in a retractable position when the paper container is being returned. Since a notch is formed along the axis of the holder to allow the tip of the claw to protrude and move, it is possible to effectively refine the paper container just before it goes from the paper container assembly device to its filling and sealing device. , it is possible to further improve hygiene compared to the conventional method.

In particular, in the rice bran washing device, the simultaneous feeding and discharging of paper containers is performed by a pawl mechanism of a sliding member that reciprocates linearly along each holder diametrically opposed to the rotating body. Moreover, the claw mechanism of the combined discharge device configured in this manner is maintained in the protruding position during forward movement and in the retracted position during return movement, and has a vertical line direction on the holder side that allows the protruding transition of the claw tip. Since the notch is provided, there is an effect that the feeding operation can be performed reliably without damaging the flexible paper container.
