Description

[Detailed Description of the Invention] This relates to a machine for packaging with plastic film. Equipment and control function tThus, it is characterized in that the belt interval for conveying trays and the interval of chains for continuous film shooting can be automatically set variable according to the size of the input tray. It is something.

This type of packaging machine is basically a modified bag-making machine, and depending on the size of the tray, there is a space between the side belts that hold and transport the tray from both sides, and a moeki tray. Although it is possible to adjust the distance between the pair of endless chains used to transport the wrapping film with just one hand, the size of the tray must be adjusted according to the size of the packaged items. Since manual adjustment is required every time a change is made, the adjustment work is cumbersome and inefficient.

In view of the above points, the present invention connects the above-mentioned double transport device d to a storage device, and by simply inputting the tray size as a numerical value with a button, the interval between the @Kiya transport devices is automatically variably adjusted. It was made as possible.

Hereinafter, practical examples of the present invention will be explained based on the drawings.

A switch Cl8) is provided to separate the brake motors (four, rotational speed detection value fil 146) from each other.

It is connected to the electronic storage device t251.

At the front ends of the above-mentioned both strip plates 1:17) +37), threaded pins 149) and +9) are installed vertically, and via these pins both strip plates j, (7) l'37) and the aperture rotating body are connected. 12+ +2

A practical example of the tree is constructed as described above, and the operation will be explained below.

When both sides of the film (iF) are held between the clips sunk in the chines (1a) (la) on both sides, the film begins to be moved by the rotational action of the chinos (t). Figure 2 shows the number.

Since the film can be folded into place, the film is rolled into a cylindrical shape around the tray. The tray fT) is then conveyed by being held between both sides by a belt conveyor +31f31.
On the way, the film fFl rolled into a cylindrical shape as described in 1jill is cut by a push-cut 44 mechanism 1 (6) between each tray, and the end of the cut film is cut into the F of the tray fT) by known means. Can be folded to the side.

Therefore, it is necessary to change the size of the tray fTl in accordance with the type and size of the supporting equipment. Are there various types of trays with different sizes, groove widths, and depths? The electronic storage device 125) outputs a signal adapted to the tray to be used based on the pre-recorded data L to the motor (1) shown in Figure 3 and the motor 14 shown in Figure 5.
