Two pairs of upper pawl body 21a and two pairs of intermediate pawl bodies 22a are rotated relative to the shaft S in accordance with rotation of the upper gap adjusting screw 23h or the intermediate gap adjusting screw 24h The upper first left pulley 49a, the upper second left pulley 49b, the upper third left pulley 49c and the upper first right pulley 49d and the intermediate first left pulley 49e, The intermediate first right side pulley 49f and the intermediate second right side pulley 49g and the intermediate third right side pulley 49h are rotated along the follower belt 43 without increasing or decreasing the length of the follower belt 43, Can be moved.

The lapping machine of the shrinkable film for containers according to the present invention is characterized in that the lapping machine of the container comprises a fixture 41a fixed to the back of the back frame 100 and having a through hole 41b drilled in the transverse direction, A flow rods 41c extending from the fixed rods 41a and extending to the left side of the fixing rods 41a through the through holes 41b while being extended from the flow rods 41d, And a left fixed idle gear 41 which is supported by the fluid bundle 41f and meshes with the driven belt 43. The left idle gear 41f and the left fixed idle gear 41f,

The left fixed idle gear 41 is elastically moved along the through hole 41b of the fixture 41a by the spring 41e fitted in the flow rod 41c so that the two upper rotation rollers 11 and the intermediate Even when a load is applied during rotation of the rotary roller 12, it is possible to elastically buffer the rotation of the rotating roller 12. Particularly, when the upper gap adjusting screw 23h or the intermediate gap adjusting screw 24h rotates in the forward and reverse directions, Even if two pairs of the upper gear 31 and the intermediate gear 32 are close to or spaced apart from each other (even if the pair of intermediate pawl bodies 22a and 22b are close to or spaced apart from each other with respect to the shaft S) It is possible to elastically buffer the load which can be applied to the driven belt 43 (which is long).

Next, the operation of the lapping machine of the shrinkable film for containers according to the present invention will be described as an embodiment.

Example 1 [Shrinking Film (F) Cutting and Dropping Operation)

First, the containers B are fed in a line through the conveyor C and pass through the reference position C1 one by one.

The shrink film F is supplied through the film supply line L and remains fitted in the shaft S. [

When the one-side motor M1 is rotated in this state, the right fixed gear 42 of the rotary assembly 40 is rotated by the drive belt 44 and the driven belt 42 engaged with the right fixed gear 42 43 forward and reverse the two sets of the upper gear 31 and the intermediate gear 32 disposed between the left fixed idle gears 41. [

The forward rotation and the reverse rotation of the pair of the upper gear 31 and the intermediate gear 32 are carried out through two pairs of the upper support shaft 21 and the intermediate support shaft 22 as two pairs of upper rotation rollers 11 and the intermediate rotating roller 12 are rotated forward and reverse so that the pair of upper idle rotating bearings S1 and intermediate idle rotating bearings S2 of the shaft S are also rotated counterclockwise and forward together, So that the shrinkable film (F) interposed therebetween can be lowered along the shaft (S).

When the end of the shrink film F is aligned with the end of the shaft S, the cutting bundle 50 is operated to cut the shrink film F in the horizontal direction.

Subsequently, the two lower rotating rollers 13 rotated by the lower motor M2 are rotated (normal rotation and reverse rotation) so that the two lower idle rotation bearings S3 are also rotated in the reverse and forward directions, So that the shrink film F sandwiched between the shafts S can be instantaneously dropped from the shaft S so as to be covered by the container B in a different position.

Thereafter, the container B on which the shrink film F is placed is contracted while passing through the heating chamber, so that the shrink film F can be tightly integrated with the outer periphery of the container B.

Example 2 [Shrinking film (F) cutting operation]

When the end of the shrink film F is aligned with the end of the shaft S, the cutting bundle 50 is operated to cut the shrink film F in the horizontal direction. The rotation force is transmitted to one of the sub gears 55 by the main belt 54 while the other sub gears 55 are rotated together with the sub belt 56 The shredded film F which has been lowered along the shaft S at this time can be cut in the horizontal direction at once by the rotation of the cutter 58. [

At this time, the cutter 58 rotates to enter the cutting groove S6 of the shaft S to cut the shrink film F, and the shrink film F thus cut is cut into two pairs of lower idle rotating bearings S3 To the container B which has reached the reference position C1 of the conveyor C by the pair of the lower rotating rollers 13 abutting against the conveyor C at the reference position C1.

Example 3 [Shaft (S) replacement operation]

First, in order to assemble the shaft S having a larger diameter in a state in which the shaft S is assembled, two pairs of the upper rotation roller 11 and the intermediate rotation roller 12 and the pair of front idle rotation rollers 14 And the rear idle rollers 15 should be spaced apart from each other.

The pair of front idle rotating rollers 14 and the rear idle rotating rollers 15 move the front gap adjusting rod 62 and the rear gap adjusting rod 63 along the horizontal sliding rod 61 fixed to the back frame 100 So that they can slide away from each other.

The two upper rotation rollers 11 are provided on the upper left projecting groove 23b and the upper left projecting groove 23b formed on the upper projecting step 23a of the pair of upper grippers 21a before the upper gap adjusting screw 23h is rotated, Two pairs of upper holding shafts 21 are moved away from each other so that two pairs of upper holding shafts 21a are moved away from each other, The pair of upper rotating rollers 11 supported by each other are also spaced apart from each other.

The two intermediate rotation rollers 12 are provided with an intermediate left knurled groove 24b formed in the intermediate projecting step 24a of two pairs of intermediate grippers 22a before the intermediate spacing adjusting screw 24h is rotated, The pair of intermediate pawl members 22a are moved away from each other so that the pair of intermediate support shafts 22 in the pair are also moved away from each other so that the pair of intermediate pawl members 22a The pair of intermediate rotation rollers 12 supported by each other are spaced apart from each other.

In this state, the previously assembled shaft S is disassembled and the shaft S having a larger diameter is placed again. Thereafter, the two upper rotation rollers 11 and the intermediate rotation rollers 12, It is possible to complete the replacement operation of the shaft S by narrowing the gap between the idling roller 14 and the rear idle roller 15. [Operation for narrowing the interval of the above components is possible in the reverse order of the above operation, It will be omitted to avoid complications).

The reason why the replacement operation of the shaft S can be very simplified in the present invention is as follows. The structure of the support roll 20 supporting the pair of upper rotation rollers 11 and the intermediate rotation rollers 12, The structure of the adjusting member 23 and the intermediate gap adjusting member 24 and the structure of the rotating assembly 40 for rotating the pair of the upper gear 31 and the intermediate gear 32 by the one- This is possible by a structure that enables the distance between the upper gear 31 and the intermediate gear 32 between the pair of pairs of gears 31 and 32 without increasing or decreasing the length of the driven belt 43.

The present invention can be used in the industrial field where a container is wrapped with a shrink film.
