Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a continuous packaging device using a horizontal billow packaging machine, etc., and its purpose is to tightly wrap the products to be packaged in the length direction, and The aim is to drastically reduce losses.

Conventionally, when seal-cutting the space between the packaged products in the horizontal direction using a horizontal billow packaging device, etc., the packaged products were Because the distance between the packaged items was formed with a relatively large margin in the length direction and the core part was sealed, the size of the finished bag became larger and the amount of film consumed increased accordingly. However, if the packaged product is not packaged in a box, the bag will be bulky and unsightly, which will significantly reduce the product value. There are various disadvantages such as having to do
There was a desire for packaging in extremely small bag sizes.

“When the packaged product passes through the horizontal seal cutting device section, the swinging chute provided on the packaging product removal side of the horizontal seal cutting device is tilted downward to move the packaged product toward the sealing section at the end. An embodiment of the present invention shown in the accompanying drawings will be described below in detail, in which the conventional drawbacks are eliminated by returning it to the horizontal state and cutting the rear side with an accurate transverse seal.

In FIG. 1, reference numeral 1 denotes a well-known horizontal pillow packaging device, including a bag-making device 8 for forming a continuous strip-shaped film 2 into a cylindrical film 2', and a packaged product number, etc. in the cylindrical film 2'. A packaged product feeding device 5 that feeds the packaged products at predetermined intervals, a vertical sealing device 6 that superimposes and seals the film edges of the tubular film 2', and a packaged product 4 in the tubular film holder. Each bag is provided with a horizontal seal cutting device 7 for cutting a seal in the horizontal direction to form a package 8 for each bag.

Reference numeral 9 denotes a chute that swings up and down, and is arranged adjacent to the packaged product removal side of the horizontal seal cutting device 7. The configuration will be explained in detail below with reference to FIGS. 2 to 6. 1
0.10 is a frame, which is fastened to the substrate 11 of the cutter 7 as described above.

Bearing part 12.12 at the upper end of said frame l, o, 10
Insert the shaft 13 rotatably into the
A chute side plate 14.14 is integrally coupled to the shaft 18 at both ends of the chute side plate 14.14. ．． A chute plate 15 is integrally fastened to the upper surface of the chute plate 14.

16.16 is a flange attached to one side of the chute side plate 14.14, and a cam floor l? , 1? is installed. 18 is a tension spring,
Its both ends are appropriately latched to the chute side plate 14 and the frame IO, and its tensile force always acts to pull the chute plate 15 downward.

Reference numeral 19.19 denotes a cam plate formed to engage with the cam floor 17.17, and is attached to a lower horizontal seal head mounting member 20 described below. When operated, the cam floor 17.17 slides against the cam surface 21.21, causing the chute plate 15 to swing up and down in synchronism.

Next, the horizontal seal cutting device 7 will be briefly explained.

Upper and lower horizontal seal head mounting members 25 and 20 are attached to guide shafts 28, . They are designed to be able to slide vertically relative to each other.
Both ends of the link member 26, 26, 27.27 are fitted into one end of the link member 26, 26, 27.27, and the link member 26.26.2? ,
2? The other end is connected to the lever 28.28 with a pin or the like. 29 is a rotation shaft, which is arranged at the upper part of the machine casing 2,
The levers 28 and 28 are fastened to both ends, and an operating lever 80 is further provided, and the other end of the operating lever 80 is connected with an operating shaft pin of an air cylinder 81 or the like. 82.82 is a bearing member for the rotation axis z9.

The upper and lower horizontal seal heads 88, 84 for sealing the tubular film 2' are respectively attached to the horizontal seal head mounting members 25, 20, and the well-known heating members 8
5, 35 (for example, a cartridge heater, etc.) is built in, and is heated appropriately. 86 is a cutter device, and the upper and lower horizontal seal heads, 33. 34
The center portion of the cylindrical film 2' is cut when the cylindrical film 2' is tightly sealed. 3
Reference numeral 7 denotes a belt, which is used for conveying the cylindrical film 2' on the loading side of the packaged products of the horizontal seal cutting device 2, and for discharging the completed package 8 on the unpacking side of the packaged product. It is. Although not shown, the lateral seal cutting device is reciprocated by a separate drive mechanism in the direction of the second arrow A--A in synchronization with the sealing operation of the cylindrical film.

In addition, FIG. 7 shows a case where a rotary type horizontal seal cutting device B is used instead of the vertically moving horizontal seal cutting device Y, and the rotary type The operation performed in synchronization with the rotational drive of the lateral seal cutting device f will now be described.

The cylindrical film 2' moves forward with packaged items 4, . Then, when moving forward further (during this time, the horizontal seal head i3 B,, 8
41dffi state, therefore, the chute plate 15 is in a downwardly inclined state. ) The product to be packaged moves forward along the downwardly inclined chute plate 15, but at this time, the product to be packaged slides down in the direction of movement within the cylindrical film holder due to its own weight.
The charging tip is reached (see Figure 4).

Next, when the lower horizontal seal head mounting member 20 rises, the chute plate 15 is gradually rotated upward via the cam floor 17 that engages with the cam surface 21 of the cam plate 19, and the upper and lower horizontal seal beds 8184 Before the cylindrical film 2' is closed and sealed, it returns to the horizontal state and the space 2'' of the cylindrical film 2' (see FIG. 2) is sealed.

By making the cam surface 21 uneven as shown in FIG. 6, it is possible to vibrate the chute plate 15 and cause it to rise, thereby helping the chute plate 15 slip off due to its own weight.

After the seal is cut as described above, the upper and lower horizontal seal heads 88, 84 are separated from each other again and are in an open state, and the chute plate 15 is tilted downward, so that the package 8 slides down on the chute plate 15. Bell) 81'lK- is therefore discharged.

According to the present invention, a swinging chute is provided adjacent to the packaging product removal side of the horizontal seal cutting device, and the swinging chute swings the tip end side up and down in synchronization with the opening and closing operations of the upper and lower horizontal seal heads. When the bag passes through the horizontal cool cut device section, the swinging chute is tilted downward to bring the packaged product to the 71 part side of the tip of the bag, and it is returned to a horizontal state to remove the packaged product from the side. Since the side is cut with a horizontal seal, it is possible to package the packaged items tightly in the length direction, and as a result, the bag size in the length direction can be reduced, and bagginess in the film can be eliminated.
It is possible to greatly reduce film loss, which is extremely economical, and since the horizontal seal cut is performed while keeping the same horizontal plane with the subsequent packaged products, correct and beautiful seal cuts can be made, resulting in a good-looking product. It has the advantage of producing packaging with high commercial value.

In this embodiment, the up and down movement of the chute plate has been explained using a cam, but it is also possible to do this by operating an air cylinder or the like, and any suitable operating means can be used.

Further, regarding the lateral seal cutting device, although a vertically movable type is described in this embodiment, a rotary type as shown in FIG. 7 may also be used.
