Description

[Detailed Description of the Invention] <<Object of the Invention>><Industrial Application Field> The present invention provides a method for packaging canned goods, etc., in a fixed quantity, for example, in batches of several pieces, in a tube-shaped net package. The present invention also relates to a method and apparatus for packaging fragile items suitable for simultaneously loading labels.

<Background of the Invention> Food products and the like have conventionally been packaged using packaging bodies made of tube-shaped nets. This packaging means is becoming widely used because, depending on the shape of the objects, the objects can be packaged in an aligned manner, making handling convenient and displaying them more effectively in stores. However, most of these packaging methods are currently filled manually, which involves dropping the packaged object into a tube-shaped package with one end closed through the other opening. Most of the work is like this. Therefore, this method cannot be applied to packaging fragile items such as canned goods and other fruits, whose appearance is easily damaged by the impact caused by dropping them. Efficiency has deteriorated significantly. In addition, in this type of packaging, a label indicating the contents is loaded at the same time, but a sufficient method for smoothly and reliably performing this has not been disclosed. In other words, Japanese Patent Application Laid-Open No. 51-100887 discloses a label filling method, but the label and the packaged object are sent out at the same time, and then combined with the packaging net, and the feeding speed etc. If there is misalignment, the labels may become wrinkled or bent, making it difficult to load the labels reliably.

<Problems attempted to be solved> The present invention was made in view of this background, and it is capable of efficiently filling even packaged objects such as canned goods that require relatively careful handling. In addition, the present invention attempts to propose a new packaging method and packaging device that can reliably load labels and the like.

<<Structure of the invention>><Means for achieving the object> That is, the first method of the packaging method for fragile items according to the present invention is to place the free end of a tube-shaped package with one end closed against a guide frame arranged approximately horizontally. On the other hand, the objects to be packaged, which are arranged in unit numbers, are passed through the inside of the guide frame all at once to fill the package, and are guided so that they are separated from both the package and the objects to be packaged. A label fixed to a string that is integral with the package at one end is passed through a label slit provided along the frame to fill the package.
After that, the free end of the package is closed.

Furthermore, in a second method of packaging fragile items according to the present invention, the free end of a tube-shaped packaging body with one end closed is fitted onto a guide frame arranged approximately horizontally, while The packaged objects are passed through the inside of the guide frame all at once to fill the package, and the label slits provided along the guide frame are placed so as to be isolated from both the package and the packaged objects. , filling the package by passing through a label fixed to a string that is integral with the package at one end;
After that, the free end of the package is closed, and then the package is heated to cause heat shrinkage.

Furthermore, the packaging device for fragile items according to the present invention includes a guide frame arranged almost horizontally for storing a tube-shaped package in a state of being rolled up on the outer periphery; a label slit provided so as to be isolated from both; a supply device provided at the rear of the guide frame and feeding the packaged objects in unit numbers forward through the guide frame; A binding machine is provided in front of the guide frame and binds the package so as to divide the front and rear of the package each time a unit quantity of the packaged articles is filled.

The present invention attempts to achieve the above object by taking these technical means.

<Operation of the Invention> In the present invention, first, the free end of the tube-shaped package with one end closed is rolled up to fit outwardly into the guide frame which is arranged substantially horizontally. On the other hand, the objects to be packaged in units are pushed out at once through the inside of the horizontally arranged guide frame by the feeding device. As a result, the objects to be packaged are smoothly fed and loaded into the package without damaging each other. At this time, the label from the label slit is simultaneously fed out at approximately the same speed as the packaged object is pushed in and loaded into the package. At this time, since the label passes through the label slit independently so as to be isolated from both the packaged object and the packaged object, the label is sufficiently protected at this stage when it is easily damaged. This will ensure that the label is loaded correctly.

<Example> The present invention will be specifically explained below based on the illustrated example. In this explanation, an apparatus for carrying out the method of the present invention will first be explained, and while explaining its working mode, , the method of the present invention will also be explained.

Reference numeral 1 denotes a packaging device for fragile goods according to the present invention, in which a stocker 2 for storing a tube-shaped package P is provided in the center, and a stocker 2 is provided at the center for storing a tube-shaped package P. A feeder 3 is provided at the front (defined as the front), and a pusher 4 is further provided at the rear. These feeder 3 and pusher 4 supply the object to be packaged A, and these two members are collectively defined as a supply device. On the other hand, a binding machine 5 is provided in front of the stocker 2, and a shrink tunnel 6 is further provided following it. To explain each of these members below, the stocker 2 has a cylindrical guide frame 11 arranged horizontally on the upper surface of the table 10, and this guide frame 11 has its front and rear ends. 12 Form into a shape that expands slightly outward. The reason why the guide frame 11 is arranged horizontally is to prevent the packaged object A passing through it from falling by itself.
It does not require that it be in a safe horizontal state, but it may be in a nearly horizontal state within the range that suits the purpose, and this guide frame 11 may be in a trough shape with an open top to the extent that its functional purpose can be achieved. , or any other suitable shape. This guide frame 1
1 stores the object to be packaged A in a rolled-up state on its outer periphery. Further, as an example, a label slit 13 is integrally formed in the upper part of the guide frame 11.
From here, label L is placed inside the package P at the same time as packaging.
Configure to supply. Of course, this label slit 13 only needs to be along the guide frame 11, and does not need to be formed of an integral member. Such a guide frame 11 is fixed at the rear end to the side edge of the feeder 3 by a clamp 15.
In this embodiment, for the guide frame 11 filled with the packages P, one is prepared as a spare on the side, and when the packages P are used up, the stocker 2 is replaced and used. Do it like this. Next, the feeder 3 and pusher 4 that constitute the feeding device will be explained. First, the feeder 3 has a feeder frame 16 provided with a conveyor 17 that is driven intermittently, and a large number of stock trays 18 are formed for this conveyor 17. The stock tray 18 is, for example, a receiving frame having a V-shaped front surface, and the objects A to be packaged, such as canned goods, are stored in an aligned state on the upper surface of the receiving frame. The structure is such that one of the stock trays 18 always stops in alignment with the guide frame 11 as the conveyor 17 moves intermittently.
Furthermore, to explain about the pusher 4 provided at the rear of this feeder 3, this one is a table 20.
The slider 4a of the cylinder, which is constituted by a cylinder provided on the upper part and which essentially acts as a pusher, is slidable from the stock tray 18 to a range that fully penetrates the guide frame 11. Has a stroke. Next, the binding machine 5 will be explained. This binding machine 5 is provided on a table 23 and has a conventionally known configuration. That is, in this embodiment, the coil-shaped binding wire W is guided to the binding head 25, and the binding wire W is guided to the binding head 25 as shown in FIG.
As shown in F, the binding wire W is cut into short pieces by the binding claw 26 and the guide 27, and then bent into a flat annular shape as the binding claw 26 is pushed in, thereby bundling the package P. It is something. Note that the binding claw 26 and guide 27 in this binding head 25
Two sets are provided in the front and rear, and each time a package P is filled with the object A, the rear end of the package P and the next package P to be packaged.
and the front ends of each at the same time. This apparatus is further provided with a shrink tunnel 6, which heats the package P filled with the packaged articles A, as shown in FIG. It is configured so that hot air is blown into the Shrink tunnel 6.

The packaging apparatus for fragile items according to the present invention has the specific configuration as described above, and operates as follows to complete packaging while carrying out the method of the present invention. This state will be explained below with reference to FIG.

() Preparation state (see Figure 5 A) (a) Filling the package First, prior to operation, the package P is prepared.This is done by removing the guide frame 11 from the clamp 15 as appropriate and placing it on a table or the like that is easy to work with. For example, a package P made of a tube-shaped net is loaded by being rolled up on the outer periphery of the guide frame 11 by utilizing this method. Of course, at this time, it is preferable to perform the same operation on the spare guide frame 11 as well. The end of the package P on the starting side, that is, the end on the front side, is pulled out at one end, and the end is closed with a binding wire W in the binding machine 5.

(b) Loading of objects to be packaged The objects to be packaged A, such as canned goods, are placed on the stock tray 18 in the feeder 3 by hand or the like as appropriate. Needless to say, at this time, as many cans as needed are arranged. Of course, in the case of such manual work, an appropriate work method can be used, such as changing the type of canned goods or changing the number of canned goods as necessary.

(c) Loading of labels Furthermore, the present invention employs a method of loading labels at the same time. Incidentally, in the case of a package P consisting of a tube-shaped net, the package itself cannot be printed with any trademark or other product indication indicating the product inside, and must be printed with other paper labels. Especially when such a package P is used, a method that allows label L to be filled at the same time is extremely useful. In this method, as shown in FIG. 4, labels L tied at regular intervals with, for example, a thin string L are supplied to the label slit 13 in the guide frame 11, and the packaged object A and the packaged object P are
It shall be kept isolated from both.
Note that one end (front end side) of the string I has already been fixed to the front end side of the package P in the previous operation, and if it is not fixed, it is fixed prior to the operation.

(d) Pusher standby During the preparation stage, the cylinder that is the pusher 4 stands by in a contracted state.

() Filling the object to be packaged A This work is performed by the pusher 4 as shown in FIG. It is pushed out from above, further pushed into the guide frame 11, and then pushed out until it fully penetrates the guide frame 11.
At that time, the packaged object A is pushed by the pusher 4 and is filled into the package P. At the same time that the packaged object A is filled, the label L moves into the packaged object P together with the packaged object A, and the label L is loaded. Then, since the strings L that tie the labels L are tied together at the binding position of the package P, the labels L are automatically pulled out one after another, and the labels L are sandwiched between the inside of the package P and the packaged object A. It is packaged in such a way that it looks like it will be washed.

() Binding After such work, the package P near the rear end of the object to be wrapped A is delivered manually to the binding head 25 of the binding machine 5, and is operated to tie it to the binding wire W. One is used to bind the rear end of the packed object A, and the other is at the front of the single item that will be packed in the next package. It binds the parts together. Of course, the work performed on the binding machine 5 itself can be performed manually. In addition, the specific work of this binding is as shown in Fig. 5 D, H, and F.
is supplied to the binding head 25, the binding claw 26
At the same time, it is cut into a predetermined size by the holder, and at the same time, it is pressed and bent into a flat circular shape by the action of a guide, and the object to be packaged A is held and bundled. After this, the cutter C cuts between the two binding wires.

() Shrink processing After performing this process, packaging at this stage may be sufficient depending on the properties of the packaged object A, but if necessary, in order to obtain a stronger packaging condition, it is necessary to The package P filled with is passed through the shrink tunnel 6. In such cases, the package P undergoes heat shrinkage due to the hot air blown out from the Shrink tunnel 6, and the packaged object A is tightly wrapped.This can cause mutual misalignment, especially when handling canned goods etc. at the distribution stage. This is a preferable method for products where it is desirable to prevent this from occurring.

<<Effects of the Invention>> The present invention has the configuration and operation described above, and the operation of filling a tube-shaped package with objects to be packaged can be performed extremely efficiently. In particular, in the present invention, since the objects to be packaged A are fed in the horizontal direction, and when the objects A are fed, the unit number of objects is fed all at once, so there is no collision between the objects to be packaged.
Since it does not cause damage, even fragile items that are easily damaged can be efficiently packaged. Furthermore, when loading the label L into the package P, the label L is guided and loaded into the independent label slit 13, so the feeding of the label L is consistent with the movement of the package P and the packaged object A. Therefore, the label L can be loaded smoothly and reliably.
