The assembly device shown in the figure is a two-unit type, and the carton bottom assembly and welding device b has a pair of six mandrels 3, 3 (total 12 ), and first and second bottom heaters 4, 4, 5, 5, which are arranged to surround these mandrels 3 and face the tips thereof, respectively.
bottom breaker 6, 6 and bottom sealer 7,
7, and a pair of carton supply devices a are also provided accordingly.

Next, the process of assembling a carton using this assembly device will be explained. First, a carton (not shown) that has been set in advance in a carton supply device a is extruded by the extrusion devices 44, 44 of the device into a mandrel 3, 3 is fitted externally. After that, the mandrels 3, 3 rotate, and the first and second bottom heaters 4, 4, 5, 5, bottom breaker 6,
6 and bottom sealers 7, 1st and 2nd bottom heating, bottom breaking, and bottom sealing are performed in order to form the bottom of the carton.
The carton with its bottom formed reaches the turret 8 with the next rotation of the mandrels 3, 3 and is taken over by it.

The turret 8 has a cruciform shape when viewed from above, and is made up of four carton receiving parts 8a, and is configured to rotate in 90° increments around a rotation axis 9.
Two of the three receiving parts 8a are always located below the parallel mandrels 3, 3, so as to receive the respective cartons.

Therefore, the cartons transferred to the turret 8 are rotated through 90 degrees, changing from the parallel state to the serial state, and are transferred to the next transfer device c.

The transfer device c is designed to intermittently transfer two cartons in series as one pit, and the two cartons thus transferred form a set and are transferred to the next spout attachment device e. Once reached, the two spouts are attached at the same time, the spouts are further welded by the spout welding device f, the top is first curled by the curling device g, and the content liquid is filled by the filling device h. .

After that, the top part is further folded in a second pattern in a pattern folding device i, the top part is heated in a heater j, and then the top part is welded and sealed in a welding device k, and then it is discharged as a product from a discharge part l. ing.

Next, regarding the spout attachment device, see Figures 6 and 7.
To explain with reference to the figure, the supply chute 11
A suction car 20 is placed at a position opposite to the outlet 11a of the
20, and these suction wheels 20, 20 are provided on the holding member 21 thereof.

This holding member 21 is attached to two sliding rods 22, 23, and passes through two guide members 25, 25 and 26, 26 fixed to the machine frame 24.

A connecting piece 28 is obliquely fixed to the connecting rod 27 of the guide members 25, 25, and a small air cylinder 29 and a large air cylinder 30 are connected to the upper and lower ends.

The right ends of the air cylinders 29 and 30 are located at the same position and are connected to a sliding member 31, through which the sliding rods 22 and 23 are also fixed.

Further, 32 forms the transfer device c, and includes a holding frame 3 for holding the body of the carton 1;
3 is a support plate that supports the bottom of the carton 1; 34 is a bent presser plate that presses the upper edge of the opening of the carton 1; the support plate 33 and the presser plate 34 have connecting rods 35 and 3;
6, which is moved up and down by an air cylinder 37.

Next, to explain the operation of this spout attachment device, first, due to the action of the large cylinder 30, the sliding rods 22 and 23, which are fixed via the sliding member 31 at the right rear end thereof, slide to the right. , the suction cup 20 provided on the holding member 21 is connected to the spout 2.
It comes into contact with the mounting seat plate 2a (see Fig. 2) and attracts it.

After that, by the action of the cylinder 30 again,
When the sucker 20 returns to the center position of the holding frame 32 of the carton 1 while adsorbing the spout 2, the carton 1 is pushed to the first stage X position by the action of the lower air cylinder 37 via the connecting rod 35. The insertion hole of spout 2 of carton 1 is
This matches the position of spout 2 which is adsorbed to 0.

Then, due to the action of the small air cylinder 29, the sliding rods 22, 23 slide to the right with a shorter stroke than the larger cylinder 30, so that the spout 2 is aligned with the spout 2 of the carton 1. After being fitted into the insertion hole, the suction car 20 stops suction and returns to its original position by the action of the small air cylinder 29.

Next, by the action of the air cylinder 37 below, the carton 1 is pressed down by the presser plate 34 via the connecting rod 36.
After holding down the open end of the carton 1 and lowering it to the second stage Y position, the holding frame 32 (i.e., the transfer device) advances one pitch in a direction perpendicular to the plane of the paper, and the carton 1 is moved to the next spout welding device f. will be transferred to.

(Problems to be Solved by the Invention) The spout supply device and its attachment device have been described above, but the conventional supply device for the water inlet attachment device has the following drawbacks.

That is, the spout 2 of the liquid paper container has a mounting seat plate 2b as shown in FIG. 2, and since the spout is intermittently supplied, the mounting seat plate 2b
During the feeding process, the comrades of b overlap below near the bending part of the feeding chute 11 (see FIG. 10),
This may increase the friction between the spout 2 and the inner surface of the metal supply chute 11, making it difficult to slip.Furthermore, since the weight of one spout is extremely small at approximately 2.5 g, The falling speed could be slow, making it difficult to consistently obtain a smooth supply of the spout, which hindered the process of attaching the spout to the carton, which had a negative impact on the entire container assembly process. .

The present invention aims to eliminate such drawbacks and to enable stable and smooth supply of the spout to the mounting device.

(Means for Solving the Problems) In order to achieve this objective, in the present invention, the supply chute of the spout connecting the parts feeder and the spout mounting device is located above the position where the cutting device is provided. The problem is solved by installing a vibrator near the bend.

That is, specifically, a supply chute connected to a parts feeder and having a bent part, a cutting device equipped with two upper and lower claws that alternately protrude into the supply chute, and a supply chute above the cutting device. It consists of a vibrator installed near the bent part of the chute, and a spout attachment device that attaches the spout with a mounting seat plate to the assembled paper container from the inside.

Embodiments Hereinafter, embodiments of the present invention will be described with reference to the drawings.

The present invention is based on a liquid paper container 1 as shown in FIG.
The present invention is characterized by a spout supply device d that supplies the spout from the parts feeder 10 to the spout attachment device e in the apparatus for assembling, filling, and sealing the container.

First, the spout supply device d and attachment device e will be explained with reference to FIGS. 6 to 10. Reference numeral 11 is the supply chute of the spout 2;
It branches into two on the way from the parts feeder 10 (FIG. 4) and is suspended in parallel toward the mounting device e.

An outlet 11a for the spout 2 is opened at the lower end of the supply chute 11, from which the spout 2 fed by the parts feeder 10 and passed through the supply chute 11 is taken out. However, the spouts 2 supplied to this outlet 11a are fed one by one by a cutting device provided in the supply chute 11.

In FIGS. 8 and 9, reference numeral 12 denotes the cutting device, and this cutting device 12 has two upper and lower arms 13, 14, a link 16 that forms a parallel link 15 together with the bases of these arms 13, 14,
17, a piston cylinder 18, and a connector 19 for connecting the piston cylinder 18 and the parallel link 15, each of which is provided in the supply chute 11, 11, respectively.

The ends of the upper and lower arms 13 and 14 each have an L.
Claws 13a and 14a are provided which are bent into a letter shape, and when the arms 13 and 14 swing due to the action of the parallel link 15 due to the reciprocating movement of the piston cylinder 18, the claws 13a and 14a alternately push into the supply chute 11. I'm starting to do that.

The upper and lower claws 13a and 14a are spaced apart in the vertical direction so that exactly one spout 2 can fit therein, so that the bottommost spout 2 that has passed through the chute 11. 2' is first the 10th
As shown in FIG. 11 to the outlet 11a at the lower end.

At this time, the second spout 2'' from the bottom, whose lower end was locked by the upper claw 13a, is opened by the claw 13a further coming out of the chute 11 and the claw 14a entering inside. Similar to spout 2', claw 14
The lower end is locked at point a, and the same operation is repeated thereafter.

In this way, the spouts 2 that are intermittently supplied to the outlet 11a of the supply chute 11 are respectively attached to cartons by the next spout attachment device.

9 and 10, 38 is a vibrator, and a total of two vibrators 38 are installed, one for each supply chute 11 and 11.

Reference numeral 39 denotes a mounting plate that effectively transmits the vibrations of the vibrator 38 to the supply chute 11. This mounting plate 39 is bent in a dogleg shape, and its lower part 39a is fixed to the surface of the supply chute 11. A vibrator 38 is attached to the upper part 39b.

The vibration of the supply chute 11 caused by the vibrator 38 is caused by the relative movement of the two upper and lower claws 13a and 14a that alternately enter the supply chute 11, so that the claws 13a and 14a vibrate with respect to the supply chute 11. will be given.

In addition, in FIG. 9, 40 and 41 are large and small cylinders different from those shown in FIG. 6 for operating the suction cup 20 and its holding member 21 at the spout installation position in the same manner as described above. , are arranged in series, with a connecting block 42 at the tip.

3' are connected.

Further, 43 is a guide block for the sliding rods 22' and 23'.

(Effect of the invention) The present invention provides a device for attaching a spout from the inside to an assembled paper container for liquids. 2
Since the machine is equipped with a cutting device with two claws and a vibrator is attached near the upper bend of the cutting device, the spout fed from the parts feeder has a mounting seat plate and is relatively light. In addition to slowing down at certain points, the supply chute has a bend, and even with intermittent feeding, the vibration of the supply chute caused by the vibrator causes the spout to overlap its mounting seat plate. There is no clogging, the flow flows smoothly, and the two claws that plunge into the supply chute alternately vibrate relative to each other due to the vibration of the supply chute, and the spout that connects the claws into the supply chute The entry into the gap is smooth, and the separation is smooth and reliable without damaging the spout.
