Description

Detailed Description of the Invention [Industrial Field of Application] The present invention is aimed at eliminating the edges that occur on both sides and above and below when a hexahedral package is molded from a thermoplastic strip sheet or a thermoplastic strip sheet coated with a thermoplastic droplet coating. An ear heating device (related to this) for attaching to the side or bottom surface.

[Conventional technology]

As a device for blowing FA air and heating C1 to the edge of the package for fusing, the first part is installed parallel to the package transport direction, and the hot air from the heating element is blown to the edge of the package. Some methods stop the floating of the package in time for the exit, and after heating the ears, transfer the package again and move on to the first pressure step.

Also, the first thing to do is to move packages in a non-intermittent manner (on a regular basis).
Some devices do this by passing the package through a fixed heating element to heat the entire package.

Furthermore, as a third method, heating elements for heating the ears of each package are provided at regular intervals on the circular plate 3 to continuously move the packages. There is one that moves the water and heats it for a predetermined period of time.

[Apex while the invention is trying to solve]

Among the heating devices mentioned above, the first one moves the package intermittently, so it continuously molds the strips and the like.
Since it cannot be used as a device for filling the contents, and it heats intermittently, is it efficient and continuous? There are drawbacks that are inferior to those that can be done.

The first method allows the package to be heated continuously without congestion, but since the heating element is fixed at one location, unnecessary parts are heated, which may cause deformation of the package and adversely affect the contents.

Furthermore, the third one can efficiently heat the ears of continuously transported packages, but...? A large number of lOM bodies are also required as the package is moved to follow suit.
Moreover, it is necessary to separately blow hot air from each heating element and to stop the heating element, making the apparatus unavoidably complicated.

(Means for solving the gap) The present invention was developed in view of the shortcomings of the conventional device. ! The purpose of this system is to effectively heat the ears of the packages being transferred in step 4, using a convenient number of grooves, and to hold the pub cages at regular intervals and rotate them at a constant speed. It consists of a heating body that reciprocates within a certain range at regular intervals ft and the stationary trajectory of the body and package, and the heating body is equipped with a heat outlet that heats each ear of each cage. shall move while holding the fixed position with the overturned package, and return quickly on the return trip, and the reciprocating time shall be set to the time required for the package to move between the same number of packages as the number of packages covered by the heating element. It is characterized by:

[for f]

Packages formed into approximately hexahedrons are held at a constant distance of 7.7 mm and rotated at a constant speed. The ear part 1 of the bar cage is heated by the reciprocating heating element.

Heating body? Is this a heat vent that can heat each ear of the compound concave package at the same time? Because each ear is placed exactly 1
10: I can do 't'8.

And is the heating element the ear part of the package? Since the package is moved to the top of the wave by °C while maintaining the position where it can be heated, the necessary amount of heating can be applied to the ears.

In addition, the heating body reciprocates within a certain range, and on the outward journey it heats while holding the overturned package in a fixed position, and on the return journey it returns quickly, and the heating body covers the reciprocating time. By setting the time for the packages to move between the same number of packages as the number of packages, it is possible to transfer the packages without heating them, and quickly return to the original position after heating to finish the heating. The music that overturns the next unheated pa-so cage and rotates with the package again? By repeating the reciprocating process 1h of the heating element, the edges of the package being transferred can be sequentially processed for 5h.

The number of packages and the reciprocating range that the heating body heats at one time are determined as appropriate depending on the rotational speed of the transporting body, the acceleration, the force of the cylinder, and the amount of heating for wrapping the ears. .

〔Example〕

FIG. 7 shows an embodiment of the uninvented device, +11 is the transport body -
Then, the package i31, which is autographed at a constant speed and sent from the left-forming station (2), is transferred one after the other.

(5) is a heating element, which has a built-in heating means such as Nichrome (6), and injects hot air from a heat outlet (7117). The heat outlet (7) 47)... is connected to each ear part (41 (41...) when the package (3) is being transferred.
The heating element (5) is provided in correspondence with the position t, and the heating body (5) is moved on the circumference of the transfer body (1) by 1!8] on the longer diameter than the circumferential surface that grips the package (3) of the transfer body (1). (1) rotation axis +J
A swinging arm f911 whose base is loosely attached is supported coaxially with +.

The swinging arm (q) (this is provided with a drive pin OO, and the drive bottle head is connected to the cam aO.According to the oral tradition of the cam nO, the movable bin a0 moves up and down and back and forth, so the swinging arm (Φ) 9) also moves up and down, but the base is pivoted.
As a result, the receiving body (5) also rotates, and the transporting body (1)
) to drive a certain range of UEs in the forward direction.

The heating element (5) is made large enough to heat the package (3) of q@ at the same time, and the reciprocating range of tv-K (51 is the range of 3@ of the package, but only in the same direction of the movement of the mohatkuji). The speed of the cam to maintain the fixed position with the coated qlI!I package (3) is set so that the return time in the opposite direction is the same as the transfer time for one package I31. Set the speed of the fly, the axis, and the oral speed.

In addition, in the embodiment, the package coating of the added M body (5) is covered by the epsilon decoy, and the forward trip advances by 3 times the rotation time with the covered package, and the return trip takes the rotation time of the package/tin. However, the size of the rIA body (5), the range of reciprocating movement, etc. are not limited to this.

[Effects of the Invention] In the present invention, the heating body f51 reciprocates and the transfer body (1) moves at a constant speed to the pan cage (3). Since it is moved continuously, /(
The heating process of the ear part (4) of the package (3) can be carried out efficiently, and the molding of the package and the filling of the contents can be done from a-rule w1h! This is something that can be fully accommodated by continuous practice.

In addition, since the heating element (5) is reciprocated in one continuous heating step, the ear can be heated without installing a large-scale heating means, and the heating source can be made smaller and more efficient.
