Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a boxing device in an automatic pouch packaging device that fills food and drink products into pouches and stores the pouches in a case.

Recently, a method has been adopted to fill small bags (generally called stand pouches) with liquid or solid food and drinks so that they can be carried and used. An automatic bag packaging device has been developed in which a series of operations are performed automatically.

In this case, the filling operation into the sachets can be made more efficient by increasing the size of the device, but there is a limit to the packing speed, which hinders the efficiency. The general procedure for packing boxes is that when a predetermined number of small bags (e.g. 8 bags) are lined up in a row, the pouches are pushed into the support frame by the pushing means, and then fed into the waiting case below. Measures are being taken. In this case, the above sachets are filled at 120% per minute.
It is possible to obtain efficiency of 1 or more, but
When packing 8 bags in 5 rows as described above, the VC must supply all the bags in the support frame within 4 seconds while the 8 bags are being sent out, and return to the next receiving state. In view of this problem, the present invention connects two of the above-mentioned support frames, allows them to move back and forth in the lateral direction, and pushes the pouch into one of the support frames. In between, the pouches filled in the other support frame are fed into the case, thereby allowing sufficient time for feeding into the case and returning to the case, thereby improving the efficiency of box packing. It is.

The present invention will be described below based on embodiments shown in the drawings.

In FIG. 1, an automatic pouch packaging device 1 includes a filling machine 2 for filling one pouch W (FIG. 6) with heat-sterilized drinking water, etc., a cooling means 3 for cooling the pouch W, and a pouch box for packaging the pouches.

b is a guide rail connected to the connecting rod 24 and attached to the top plate 22 so that when one is in the extrusion position A of the pouch W, the other is located on the waiting position Bl or B2 of the case 0; The transverse cylinder 25 is slid left and right along lines 34 and 35. One of the guide rails 35 is opened at the extrusion position A, and the opening width is the same as that of the receiving frame 23.
a, 2! It has the same width as t'b, its both ends are bent toward the supply conveyor 9 side to form a guide wall, and the side opposite to the feeding side with respect to the supply conveyor 9 is extended onto the conveyor to form a small bag. A stop flange 35, a for W is formed.

The case supply means 40 includes case receiving members 41a and 41b provided below the case timing positions Bl and B2, and a case supply conveyor 42 provided opposite to the case receiving members.
42b and a case delivery conveyor 46 provided below the case receiving member.

The case receiving members 41a and 41b each have a bracket 46a attached to the frame 21 at one end.

A swinging conveyor 45a has one end pivotally supported by 46b.

, 47b are horizontally supported, and the booth (l conveyor 42a
, 42'b, and when the small bag W is stored, the swinging cylinders 47a and 47b are tilted and the case 0 is completely fed onto the conveyor 43. If necessary, an intermediate guide roller 48 is provided to smooth the transfer from the swinging conveyor to the delivery conveyor.

In the figure, 50 is the case timing position B1. This is a pouch push-out member provided above each of B2, which is provided as necessary, and is mainly composed of a push-out plate 51 and a cylinder 52 for pushing down the push-out plate 51.

Next, its effect will be explained.

The receiving frames 2'3a and 23b are, for example, one receiving frame 2.
3& is at the extrusion position A, and the other receiving frame 251) is at the case timing position E2.

In this case, the support plate 31 of the receiving frame 23a at the extrusion position AK
a is advanced and a row of small bags w' is placed between it and the supply conveyor 9.
It is stopped after an interval of 6.6 seconds (Fig. 2). In this state, the small bags W fed out by the cooling means 3 are countered by the counting member 11 provided on the supply conveyor 9, and are also resisted by the protrusions 12 toward the sea side, causing them to tilt as shown in FIG. They are fed in, abut against the stopper 35a, and are stacked one on top of the other.

When a predetermined number (for example, 8) of small bags W are accumulated on the front surface of the press plate 16, the press plate 16 is
After pressing tB, the bag is pushed into the pouch wl receiving frame 23a, and immediately returns to the old position after the pushing is completed. During this pushing operation, the next pouch W to be fed is prevented from entering by the blocking surface 16b of the pressing plate 16. After the above pushing operation is completed, the receiving frame 23
The support plate 31a of a is operated by the cylinder 32a.
The individual distance M is retracted in preparation for the next push.

In this case, although not shown, the partition plate S (FIG. 7) may be supplied by an appropriate partition plate supply means.

After the above pushing operation is repeated a predetermined number of times (for example, 5 times),
When the transverse cylinder 25 operates, the receiving frames 23a and 23b are moved, and the receiving frame 25a containing the pouch W reaches the case timing position Bl, and the other receiving frame 15b reaches the push-out position. The pouch W is subsequently pushed into the receiving frame 23b in the same manner as described above, and at the same time, the bottom plate 27a is pulled toward the cylinder 28a at the case timing position Bl, opening the lower part of the receiving frame 25a.

As a result, the pouch W is pushed down by its own weight or by the pouch pushing member 50, and is housed in the case C that moves downward. When the pouch W has been stored in the case C, the swinging conveyor 45a is tilted backwards to the swinging cylinder 47a, and the bag is moved onto the case delivery conveyor 43, and is transferred to the next process by the conveyor, and is oscillated. When the conveyor 45a returns to the horizontal position, the next case C is supplied onto the swing conveyor 45a by the case supply conveyor 42a.

During the boxing operation of small bags from the receiving frame 25a, the other receiving frame 25b is stuffed with small bags W, and after the filling is completed, the receiving frame 23b is placed in the case timing position B2. 23a returns to the extrusion position A, and the above operation is repeated.

As described above, according to the present invention, a pair of receiving frames is provided, and while the pouches are being packed in one receiving frame, the small bags in the other receiving frame are packed into the case. There is plenty of time to pack it into the case,
Therefore, even if the number of pouches fed from the supply conveyor per unit time increases, malfunctions will not occur, and reliable boxing can be performed.
