Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method and apparatus for automatically supplying film for packaging articles such as toilet roll paper.

Conventionally, for example, when wrapping multiple toilet rolls with synthetic resin film, it was possible to automatically supply a bag-shaped film and then automatically wrap the multiple toilet rolls with this film. However, there is a disadvantage in that it requires a great deal of labor from the operator.

The object of this invention is to eliminate the above-mentioned drawbacks caused by conventional film packaging and to automatically supply packaging film.

In this invention, a bag-shaped packaging film hung on a stick is sucked and transferred, the packaging film is placed horizontally on one side of the mounting table, and the packaging film is transferred to the other side of the mounting table. Then, the opening part of the bag-shaped packaging film is expanded while suctioning from above and below, and the packaging film having a certain characteristic is automatically supplied at the point where the opening part of the expanded packaging film is supplied to the opening support. A method and apparatus thereof.

Next, one embodiment of the automatic packaging film feeding method and device of the present invention will be described.

Two holes 6.degree. 6 are provided in parallel at the welded portion on the opposite side of the opening portion 2 of the packaging film 1 which is heat-sealed into a bag shape.

Two hanging rods 4.4 are inserted into the holes 5.6 of this bag-shaped packaging film 1, and a large number of packaging films 1 are hung on the hanging rods 4.

The hanging is a suction pulling sound 115 on the packaging film 1 hung on the rod 4.
is moved forward, air is sucked through the suction port 5', one sheet of packaging film 1 is sucked onto the suction/separation section 5, the suction/separation section 5 is moved back, and the packaging film is moved in a trench near the mounting table 6. .

A suction transfer section 7 provided at the top of one side 6' of the platform 6
The packaging film 1 is moved forward and suctioned to the suction separation section 5, and the one packaging film 1 is suctioned by the suction lower' of the suction transfer section 7, and then
The suction of the suction separation unit 5 is stopped, and the suction transfer unit 7 is moved back from one end of the platform 6 to the other end so as to cross over the platform 6, and the suction of the suction transfer unit 7 is stopped. By stopping the packaging film 1, the packaging film 1 is placed horizontally VC on one side 6' of the mounting table 6 177.

A transfer section 8 is provided from one side 6' of the platform 6 to the other side 6''.The transfer section 8 consists of two parallel chains 8' each having claws 8'' at a predetermined interval. , by moving the tune 8' of this transfer section 8, the packaging film 1 is transferred from one side 6' of the loading table 6 to the other side 6'.
'Transfer to.

Two notches 9.9 are provided at the 6″ end of the other side of the platform 6.
will be established. Suction ports 10', 10' of the suction volume 1'' portion 10 are provided in the notches 9, 9 at the top and bottom, and suction is sucked from the suction ports 10', 10' of the suction openings 10, thereby removing the packaging film 1. The opening part 2 is sucked into the upper part 1111 and the lower part.

Move the suction opening 10 forward to the side where the opening support 11 is present, and gradually expand the VC of the lower arm 10'' and the lower arm 10'' of the suction volume unit 10. As a result, the opening portion 2 of the packaging film 1 being sucked into the suction port 10' provided at the tip of the arm 10'' gradually widens.

7- After the opening portion 2 of the packaging film 1 was fully expanded by fully expanding the arms 10'' and 10'', the suction opening 10 was moved forward to completely expand and open the packaging film 1. The opening portion 2 of the film 1 is connected to the opening support 1.
Put it in 1. In order to facilitate insertion of the opening portion 2 of the packaging film 1 into the opening support 11VC, the side walls ii', i-i of the opening support 11, with the side walls 11', 11' having a U-shaped cross section facing each other, are tapered. After deforming, the opening 11 minutes 2 of the packaging film 1 is inserted into the opening support 11V (then the side wall 11').

11' is changed from a tapered shape to almost parallel, and by sucking air from the opening support 11 11, the packaging film 11 is inserted into the inside of the open support 11 in the form of multiple layers VC. The suction opening 10 then retreats while narrowing the upper and lower arms 10'', 10''.

After the opening support 11 has been completely supplied with the packaging film 1, the rotary plate 12 to which the opening support 11 is attached is rotated in substantially the same manner as before, and a plurality of packaging films 1VC and toilet roll paper are machined from the inside of the opening support 11. The packaging film 1 is removed from the opening support 11 while being inserted, and the opening part 2 of the packaging film 1 is wrapped as a heat-melting eyebrow.

3. The two holes 6, 6 in the thread extension 4 provided at one end of the packaging film 1 can be used to make it easier to hold the package by inserting a person's fingers when carrying it around after packaging. can.

According to the present invention, the opening portion of the packaging film can be automatically and efficiently expanded by the machine and fed to the opening support.
