Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a fabric shake-off box used for stacking continuous lengths of fabric in a folded state.

[Background of the idea]

For example, as shown in FIG. 1, a shake-off box 3 is used as a means for stacking continuously transported fabrics 1 onto a cart 2 while folding them. This shake-off box 3 is open at both upper and lower ends and is suspended by a support rod 5 suspended from a base frame 4 so as to be able to swing like a pendulum, and is connected to a crank board 6 to this shake-off box 3. A connecting rod 7 is connected. Therefore, due to the rotation of the crank disk 6, the shake-off box 3 is swung in a pendulum-like manner using the upper end of the support rod 5 as a fulcrum, and due to this swinging action, the fabric inserted through the shake-off box 3 is Trolley 2 in the folded state
It is loaded on top.

However, the conventional structure of the above-mentioned shake-off box is a frame-shaped box in which the four side walls (front, rear, left, and right) are formed of flat plates, and since the guide wall surface that guides the fabric 1 from side to side is a flat plate, the fabric 1 is When vibrating from side to side, the fabric 1 and the guide wall may come into close contact with each other, or air may accumulate between the fabric 1 and the guide wall, especially when the fabric is folded at a high speed. , the fabric 1 could not be folded smoothly, causing problems such as uneven loading.

[Purpose of invention]

The present invention was made by focusing on such conventional problems, and aims to smoothly slide (slide) the fabric 1 along the inner wall surface of the shake-off box when the fabric 1 is guided to the inner wall surface of the shake-off box. It is an object of the present invention to provide a box for shaking off fabric.

[Example of idea]

The present invention will be explained in detail below with reference to FIGS. 2 and 3.

Reference numeral 11 denotes a shake-off box according to this embodiment, and a large number of air vent windows 14 are formed on the fabric guide side walls 12 and 13 located on the left and right sides of this box. Further, the outside of each air vent window 14 is covered with a cover plate 15 made of a soft vinyl sheet or the like.
The upper edge of 5 is pivotally supported by a support shaft 16. The rest of the structure is the same as described above, and it operates in a pendulum-like manner by the rotation of the crank disk 6, and by this operation, the fabric is swung onto the cart 2.

Next, the function of the shake-off box 11 will be described.
Since a large number of windows 14 are formed in windows 2 and 13, if this box 11 is tilted to the left as shown in FIG. Since the air between the wall surface 13 and the wall surface 13 is exhausted to the outside through the open window 14,
The fabric is smoothly shaken off along the guide side wall surface 13 without creating an air pocket between the fabric 1 and the fabric guide side wall surface 13. Furthermore, when the box 11 is tilted to the right, each window 14 on the right wall surface 13 is closed by a lid 15;
External air is forced into the box 11 by the closing operation of 5, and this forced air releases the contact pressure between the right side wall surface of the box and the fabric 1, and also closes the window on the left side wall surface 12. 14 opens, the air between the fabric 1 and the left wall surface 12 is discharged to the outside through the open window 14, as described above.
The fabric 1 is smoothly shaken off along the guide side wall surface 12. Therefore, this shake-off box 1
1 has the effect of smoothly and orderly loading the fabric onto the trolley 2 in a meandering manner even when the fabric is shaken off at a high speed.

[Summary of the idea]

As described above, the present invention provides a shake-off box for shaking off continuously descending fabric to the left and right, and a large number of windows are bored in the left and right side walls of the box that come into contact with the front and back of the fabric. Together with these windows, when the box tilts to the left, it closes the window on the left wall and opens the window on the right wall, and when the box tilts to the right, it closes the window on the right wall and opens the window on the left wall. This box is characterized by having a window cover that can be opened.

[Effect of idea]

Therefore, according to this shake-off box, when the fabric is shaken from side to side by the left-right swing of this shake-off box, the window provided on the left and right side walls and the window are hung so as to open and close. The action of the lid prevents air from forming between the left and right walls of the box and the front and back surfaces of the fabric, and the action of pushing air into the box that occurs when the lid is closed prevents air from forming between the left and right walls and the front and back surfaces of the fabric. As a result, even when the cloth is shaken off at a high speed, the cloth can be smoothly shaken off in a meandering manner.

Claims (1)

[Scope of utility model registration request] In the shake-off box for shaking off the fabric that is continuously lowered from side to side, a large number of windows are bored in the left and right side walls of the box that come into contact with the front and back of the fabric, and these windows are equipped with the above-mentioned When the box tilts to the left, the window on the left wall can be closed and the window on the right wall can be opened. When the box tilts to the right, the window on the right wall can be closed and the window on the left wall can be opened. A fabric swing box characterized by having a lid.
