Description

[Detailed Description of the Invention] The present invention relates to a rolling method and device for making chicks by rolling sheets of leather, fake leather, etc. In particular, the present invention relates to a rolling method and device for making chicks by rolling sheets of leather, fake leather, etc. In particular, it is possible to perform continuous rolling to improve the processing efficiency in wrinkling sheets. Continuous rolling processing method and apparatus for leather sheets (2).

Conventionally, the method for exposing the chicks on the original flat surface of this type of leather sheet is to partially rub the sheet surface and apply a sheet presser roll to the part after the rubbing process. The sheet is moved forward by a predetermined distance by holding it there, and then the unprocessed part after the part that has been rolled is processed intermittently (after the rolling process is completed). It is common to apply the required number of chicks to the entire surface of the sheet, but the processing and feeding operations were performed intermittently.

The present invention provides a method and apparatus for continuous rolling of leather sheets, which greatly increases processing efficiency by continuously rolling sheets of leather, fake leather, etc. while feeding them at a required speed. 11 The gist of the invention is to arrange a plurality of pairs of rolls in which the rolls are pressed against each other vertically in parallel at a predetermined interval, and to simultaneously rotate at least one roll of each pair of rolls. A pair of adjacent rolls is moved in parallel by differential crank movement at a predetermined angle, and one of the adjacent pair of rolls 2, 22 is caused to perform a reciprocating motion of descending and rising periodically by a predetermined intermittent motion. be.

Hereinafter, one embodiment of the present invention will be described with reference to the drawings. A pair of rolls 2 is provided between the bearings 1 on both sides (two rolls of a predetermined length are pressed together vertically and rotatably, and A crank 4, which is rotatably fixed to the machine frame a, is connected to each bracket 3, which is integrally extended, in the same phase, and a motor 6 is connected to each crank 4 by a chain 5.
The driving force of each crank 4 is mechanically transmitted to synchronize the cranks 4 so that they rotate in the same manner, and a spline shaft joint 8 is relayed to the outside of the machine frame a via a unitary joint 7. A roll drive shaft 9 is installed vertically, and the drive shaft 9 is connected to the bevel ear 1 with respect to the lower roll 2a of the roll pair 2.
0.11 mesh (two up and dynamically connected, the drive shaft 9
is mechanically transmitted to a motor 13 by a chain 12 to constitute an oscillating roll body A.

(2. Between the bearings 21 on both sides: A pair of rolls 22 is provided in which two rolls of the same length as the rolls of the roll pair 2 are rotatably pressed together under -L, and integrally connected to each bearing 21. Target C
A crank 25 rotatably supported on one end of a connecting plate 24 is connected to each of the two brackets 23 in the same phase, and the other end of each connecting plate 24 is connected to the machine frame a. The connecting plate 24 supports each protrusion 25 in a swingable manner.
The driving force of the motor 27 is mechanically transmitted by the chain transmission mechanism 26 via the other end, and the cranks 25 are synchronized so that they rotate at the same time. A roll drive shaft 3o with a spline shaft joint 29 relayed thereto via a multi-joint 28 is installed vertically,
The drive shaft 30 is dynamically connected to the lower roll 22a of the roll pair 22 (through gears 31 and 32), and the drive shaft 30 is mechanically transmitted to the motor 34 by the chain 33, and One end of a support rod 35 is rotatably attached to a predetermined intermediate position of the connecting plate 24, and the other end is mounted and supported on an eccentric cam 37 coaxially fixed to a camshaft 36, and the camshaft 36 is intermittently fixed by an appropriate means. The eccentric cam 37 is configured so as to be able to move one rotation at a time, and in the normal state, the eccentric cam 37 constitutes an oscillating vertically moving roll body B, which is made stationary at a position where its centrifugal point is turned to the uppermost position.

The apparatus is constructed by alternately arranging the oscillating vibrating roll body A and the oscillating vertically movable roll body B in parallel, and arranging the roll pairs 2.22 alternately in parallel in the lateral direction at required intervals.

The drive transmission mechanism between the oscillating roll body A and the oscillating up-and-down roll body B of the device, or the drive transmission mechanism for the entire oscillating roll body B, is mechanically related to each other so that their operations can be controlled organically (two related movements) as described below. It is set as follows.

Then, the sheet bare exit side in the lateral direction of the device (: is the unloading a
- A roll device 41 is installed on the take-up side (1y-) and a take-up roll device 42 is installed therein (1), and the sheet 43 fed from the feed roll device 41 is placed between the rolls of the roll pair 2.22. There is a device f which is connected to the take-up roll device 42 through the winding roller 42 in sequence.

Next, the operation and effect will be explained based on the above embodiment along with sweeping. First, the driving device is operated to operate each of the oscillating vibrating roll body A and the oscillating vertically movable roll body B, and at the same time, the take-up roll device 42 is operated. When operated, the crank differential between the cranks 4.25 of the oscillating vibrating roll body A and the oscillating vertically movable roll body B is set so that they rotate with a phase difference of 180 degrees. Matching roll pair 2,2
2 to 18 (move in parallel with one crank movement, and at the same time rotate each first roll 2a, 22a of the roll pair by rotational drive of the roll drive shafts 9, 30. The vibrating vertically moving roll body B operates the eccentric cam 37 by the intermittent movement of the camshaft 36 I: In conjunction with the roll pair 2
2 is made to perform a reciprocating motion of descending and rising regularly.

The sheet 43 which reaches the take-up roll machine 42 from the feed roll machine 41 through a plurality of rows of roll pairs 2.
2. Parallel movement due to 180 degree crank differential movement between the adjacent roll pairs 2.
By sequentially feeding the sheet between the pairs of rolls, the winding roll device 42 & 2 is used to wind up the rolled and wrinkled sheet.

As described above, the present invention is arranged such that a plurality of roll pairs 2.22 are arranged in pressure contact with each other at a predetermined interval between the delivery roll device 41 and the take-up roll device 42, Also one roll 2a.

When 22a is rotated, the pair of rolls adjacent to each other are moved in parallel by a crank differential motion at a predetermined angle.
2) Since there is a structure in which one of the adjacent roll pairs periodically performs a reciprocating motion of descending and rising by a predetermined intermittent motion, there is always a slack rate between the adjacent roll pair, and the By means of the crank differential motion of the pair of rolls that pinch and transport both sides of the slack, the slack part is sufficiently fed (the slack part is conveyed continuously at a predetermined speed between the pair of rolls while being squeezed, and the winding roll machine 42 is moved. It is something that can be wound up.

As is clear from the above description, the present invention is to rub a sheet of leather, imitation leather, etc. while feeding it at the required speed while always giving the sheet the required amount of slack, so that the rubbing process can be carried out completely reliably. Both C2 and C2 have excellent performance such as extremely high working efficiency of the rolling process.
