Field of the Invention [0001] The present invention relates to an automatic binding apparatus for wrapping a bundle of packing materials with a clip by using a clip reel to which a plurality of clips having binding grooves are connected, And a clip cutting unit for swinging in cooperation with the clip conveying unit, wherein the clip conveying unit includes a clip conveying unit having a latch type latching part, a clip material feed unit including roller parts for urging the mouth part of the wrapping material to be folded in the binding groove of the clip, And the second driving means for operating the packaging material injection unit are separately provided to individually control the operation time of the clip transferring unit, the clip cutout unit, and the packaging material input unit, Automatic clips for clip wrapping to improve productivity by controlling the operating time of the configuration It relates to an apparatus.

In general, the packaging material of the vinyl type is adhered in the form of opening one side to form a spout, and processed foods such as confectionery, bread, and other contents are stored through the spout and then the opened spout is sealed to prevent foreign matter and dust from entering from outside. It is packaged to be able to block.

Such a packaging material is generally released in a state that its mouth is sealed by thermal bonding, and the purchaser can not retrieve the contents after opening the mouth portion and use the packaging material and seal the packaging material again. However,

There is a packing material using a clip which can collect and seal the spout part again after opening the spout part according to the contents.

When the clip-closing type packaging material is packaged, the clip is released in a state where the clip is bound to the spout portion of the packaging material, so that the user can freely open and close the packaging material using the clip.

The clip is made of a thin plastic piece having elasticity and provided with a geometrical shape and cut open at one side so that the mouthpiece of the package is folded and bound to the binding groove so that the packaging material can be easily opened and then sealed And is widely used in packaging materials for various products.

However, traditionally, since the binding operation of the clip has been manually performed on each packaging material, labor costs are wasted excessively, and productivity is reduced when mass packaging is produced.

As a conventional technique for solving the above problems, there is a "seal bonding apparatus" (hereinafter referred to as "prior art") of Japanese Patent No. 10-1164347.

 [0002] Conventionally, the prior art is related to a bag binding apparatus using a clip cut out in a geometric shape so that one side is hooked with an injection part of a bag, and includes a rotation part in which the clip is joined in a roll form and is releasably supported together, A first guide groove for receiving the clips to be loosened and fixed to the other side of the support portion is formed and the inner side of the first guide groove is narrowed A first communication hole is formed on one side of the lower plate to cover the first guide groove and communicated with the first guide groove, and a second communication hole communicating with the cutout portion of the lower plate is formed on the other side of the lower plate.

The reason why the first driving means 22 for simultaneously operating the clip transferring portion 20 and the clip cutting portion 40 is provided separately from the second driving means 37 of the packaging material input portion 30 is that the size The operation time (speed) of the clip transferring unit 20 and the operation time (speed) of the packaging material input unit 30 can be set differently according to the size of the clip C and the size (vertical length) of the clip C .

7 and 8, the packaging material insertion unit 30 includes a pair of roller units 31 and 34 provided so as to be in contact with each other, and one of the roller units 31 and 34 And a second drive means 37 for rotating the first and second drive means in one direction so as to force the spout portion of the package to be inserted between the roller portions 31 and 34 to be folded in the binding groove C1 of the clip C.

The first roller portion 31 and the second roller portion 34 of the packaging material insertion portion 30 are formed by a pair of rollers 32, 33, 35, As the rollers of the first roller 31 and the second roller 34 come into contact with each other and rotate in opposite directions to each other, the wrapping material inserted between the rollers moves in the direction of the binding groove C1 of the clip C So that it is forcibly transferred.

In this case, among the first roller portions 31, the rear roller 33 includes a roller assembly 33A in which a plurality of rollers 33a are connected together by a belt 33b and rotate together.

This is because the ends of the spout portions of the packaging material are more smoothly inserted into the binding groove C1 to guide the binding packaging.
