Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is capable of continuously packaging a large number of articles at a predetermined pitch, and accurately wrapping a strip-shaped continuous package in an amount corresponding to one or more predetermined number of packages. This invention relates to a feeding device for a feeding device.

For example, when trying to attach a small spoon (B) to the outer surface of a food packaging container (A) as shown in Figure 1, two film sheets are attached (as shown in Figure 2). By intervening the spoon (13) in between and welding (C) at a predetermined position, a continuous strip of sealed packages is produced, and one spoon is attached to the sealed package (1
) r, and the packaged product (D)′ is cut into a food packaging container (A).
Attach l tc.

That is, as shown in Fig. 3, a strip-shaped continuous package (D) wound into a roll (commonly called a ladder) is fed out as appropriate by a feed roller (1), and one spoon is fed out by a feeding device (21). Cuckoo mechanism (

Paste the food packaging container (A)K using the pasting device +￥t41 f'.

In such a device, when supplying a strip-shaped continuous package (Di) to a cutter (soot structure), a cutting means (7) is used.
Therefore, it is also conceivable to feed the package at a constant width corresponding to the width of the package. On the other hand, the swelling length, shrinkage, and dimensional errors during manufacturing due to the poor quality.

The pitch P is slightly distorted due to the tension caused by the tension, and in the case of very long continuous strip-shaped packages, the dimensional errors gradually add up, and the final ((cutting) There is.

In other words, welding tc+ in the width direction of the strip-shaped continuous package (D)
When removed from the section, each package (D)' is in an unsealed state.
Become and switch.

In view of these points, the present invention has been developed by winding a strip-shaped continuous package (D+) around a rotating body such as a triangular prism in which ridge lines are formed at regular intervals, and by moving the rotating body at a predetermined angle. It is possible to reliably absorb the dimensional error of the unrolled continuous package (I) while keeping the predetermined number of points (1 or 2 or more).

Hereinafter, the continuous package feeding device of the present invention will be explained based on the drawing attached in Attachment 4-1, which is an embodiment.

Figure 4 shows the spoon 111 shown in Figure 3! This is an enlarged view of only the unwinding device (2) of the j-landing machine. This feeding device +21 (r) is a triangular prism-shaped rotating body (51), and the same [7 is triangular prism-shaped and is provided close to the rotating body (5), and rotates in reverse in synchronization with the rotating body (51). It consists of a rising prevention part I (6) and a guide roller (7) and (8) K wound up and left strip-shaped continuous package α.
)) is wound around a rotating body (6) and supplied to a cuckoo mechanism (3) which is the 11th step.

The cuckoo mechanism (3) has a disc-shaped rotary blade (:U)' that cuts the strip-shaped continuous package (I)) while crossing it. It seems to stop shedding.The twisting rotary body (5) is connected to the movement of the rotating blade (3)' of the cuckoo mechanism!1ilJ +-

1) Unwinding the package (1)) The situation in which a strip-shaped continuous package σ)) is unrolled by the rotating body (5) will be explained with reference to FIG.

A strip-shaped continuous package (D) is wound around a rotating body (51) which is a triangular prism. As shown in FIG. The packaging part (Dl) that is being placed and the packaging part (D
l) Flexible welding tc+ part, tightly connected part (D
, ) are supported by the ridgeline portion (9) of a triangular prism (indicated by the apex of the triangle and 1- in the drawing). In other words, the strip-shaped continuous package (1)) being pulled by the tension F1 is supported by the flexible connecting part (D2) on the ridge of the rotating body (5) and is pulled forward while sliding. When reaching the rigid wrapping portion (Dl) of the spoon, it cannot be bent, creating a large resistance and regulating the relative position between the strip-shaped continuous package (wall) and the rotating body (5).

In addition, when the packaging part (D,) protrudes from the predetermined position, it is pulled back by the tension F1, and it becomes above the lid U position as in the above case.

The rotating body (5) starts rotating from the state shown in Fig. 5 (a), passes through the states shown in Fig. 5 (1)), (C), (d), and (e), and then reaches the state shown in Fig. 5 (f). Condition: 120 turns, 1l
The belt-shaped continuous package (L) corresponding to one package is sent out and stopped once. Rotating body (5) or Fig. 5(c)
, (di, (e)), a gap is created between the feeding side of the strip-shaped continuous package (I) and the rotating body (5). In other words, the angle bent by the ridgeline portion becomes looser, causing the packaging part () to rise and become slippery; however, due to the presence of the rising prevention member (61), the packaging part ()
, ) can be prevented from rising.

This rising prevention member is close to the rotating body (5), and may be fixed as long as it allows rotation of the rotating body (5), but if the rising prevention member is close to the rotating body (5), If you turn it as shown in U, the packaging part (Dl) and the rising prevention member (
6) It is possible to maintain a smaller interval between the two to increase the effect of preventing rising.

For example, a presser belt, roller, etc. can be used.

If the rotor (5) is parallel and has multiple ridges at regular intervals (/'tc), it should be flat (as shown in Figure 8), or with four or more corners as shown in Figure 9. polygon (can also be one shape).

When the rotating body (5) is a polygonal prism of four or more, the internal angles of the ridgeline portions become obtuse angles, making it easy to slip. Therefore, as shown in FIG. 9, it is preferable to bend the side surfaces once and form the ridgeline part at an as acute angle as possible. However, it is undeniable that slippage is still likely to occur because the strip-shaped continuous package is stretched between adjacent ridgeline portions.

From this point of view, it is wise to form the rotating body (5) in the shape of a triangular prism, and it is more effective if the rising prevention members of the same shape are rotated in synchronization.

Note that the rising prevention member (6) is not absolutely necessary, and the rotating body (51) may be used alone as shown in FIG. ) is related to the change in the stiffness of the packaging part (Dl) and the connecting part (D, ) of the strip-like continuous package, and to the tensions F, and F2. Tension I?2
If it is too large, the deflection part (Dl) will rise over the ridgeline part of the rotating body (5) as shown by the imaginary line in Figure 7, but if the difference between Fl and F2 is within a certain range. There is no such fear inside.

In addition, either tension F1 or F2 may be increased, but if the tension F1 in the advancing direction is increased, the front end of the packaging part becomes the reference for positioning, and the tension F1 in the advancing direction is the same or increased. In this case, 1i17 becomes the reference for positional adjustment after the packaging part (1), ).

In the illustrated embodiment, the length of the − side of the triangle 11 is the length of the package a)
)' The dimensions of the four pieces are approximately equal to P, but one side of the triangular prism is the dimension of the package l))' 2- or more, and the times lFt
<Body) The cut angle of 5) may be made smaller. ll- can also be used when dispensing a package with the same number of columns as 111.

However, in order to apply the present invention 1, it is necessary that there be 1-1 changes in the wrapping portion and the connecting portion of the strip-shaped continuous package.

If the feeding and twisting position of the strip-shaped continuous package in the next process is incorrect, or if you want to set the initial V-feeding position, the starting position [phase] of only the rotating body in conjunction with the next process [7] It can be corrected by changing .

An example of the phase ljf- will be explained below with reference to FIG.

Next - [The drive shaft (1
01 is loosely fitted with the gear io1 and the sleeve 2).

A long hole (13) in an oblique direction (helical shape) is bored in the sleeve (12), and the drive shaft (10) is inserted into the long hole (13).
A pin (14) protruding from is fitted. The sleeve +12) & gear (11) are interlocked by a key (15).

Therefore, the rotation of the drive shaft (10) causes the pin f+41 [therefore the sleeve (12) to move from the three 7 (12) to the key 11
5) is transmitted to the gear (11) by conduction. Gear C11) on the drive shaft is gear 0 on the shaft (16) of the rotating body (5).
In addition to meshing with η, other gears f1st and li!
(Due to the rotation of the rotating body (5) and the rise prevention unit (6)
) are synchronized.

A male i-shi (20) is provided at the tip of the sleeve 112),
This 1111 screw f2ffl Q is the only threaded body L) that is screwed into the drive shaft (10) using a screw (221).
It is designed so that it cannot move freely in the axial direction.

Therefore, in order to change the phase of the rotating body (5), the female screw body e? l) By turning the screws (within the knob, which are integrally connected), move the seven threaded slides (12) back and forth.
let However, the sleeve (12) and the drive shaft (10) are connected by the pin 114)! #! Since the drive shaft (10) and the sleeve t12) are engaged with the spiral elongated hole, the relative turning position of the drive shaft (10) and the sleeve t12), that is, the rotary body +51,! : Drive shaft (lO
) changes in phase.

A kite roller (8) is attached to the shaft of the nof (231), which is integral with the female threaded body (21), with a bearing (241) interposed therebetween.
is supported by a shaft.

According to the device 7 for feeding out strip-shaped continuous packages of the present invention, it is possible to feed out the next step 1 (accurately) based on the number of packages or other parts having 1 + Even if the width between each packaging rib of a continuous strip-shaped package changes due to manufacturing errors or temperature changes, there will be no deviation due to the number of unrolled strips. Even when a continuous package is cut into small!11 packages fc, the cutting position will not be deviated and parts other than the welded parts will be cut, resulting in defective products.

However, if the dispensing device is provided with a rising prevention member as in the embodiment, its operation can be performed more reliably.

Furthermore, if it is possible to adjust the phase between the rotational position of the rotating body and the interlocking of the next process, even if the width of the package, that is, the pitch of the continuous band-shaped package, is different, it will be within the range that can be absorbed by the slippage of the rotating body. If so, it can be used for various strip-shaped continuous packages.
