Description

[Detailed description of the invention] [Industrial field of application] The present invention continuously and automatically produces iron-finished sheets (sheets, wrappers, tablecloths, etc., collectively referred to as sheets) and yukata. This invention relates to a device for preventing the sleeve ends of a yukata from folding when folding the yukata, in a business-use device for folding the yukata.

[Prior Art] A conventional sheet and yukata folding machine will be described below with reference to FIGS. 4 and 5.

In the figure, 1 is a roll iron,
The yukata 2 is ironed and sent to a sheet and yukata folding machine. Reference numeral 3 designates a first belt conveyor which is disposed substantially horizontally with its starting end facing the delivery port 1A of the roll iron 1. 20 is a first sensor disposed on the first belt conveyor 3,
This first sensor 20 measures the total length of the yukata 2 (the length of the yukata 2 in the traveling direction) conveyed by the first belt conveyor 3. A second belt conveyor 4 is disposed substantially parallel to the first belt conveyor 3 with its starting end facing the terminal end of the first belt conveyor 3.
Reference numeral 5 denotes a first folding knife as a sheet and yukata folding device disposed opposite to the gap between the end of the first belt conveyor 3 and the start of the second belt conveyor 4; The folding knife 5 is constructed so that the yukata 2 hangs down from the end of the first belt conveyor 3, and the folding knife 5 is activated when the yukata 2 hangs down to 1/2 of its total length. Reference numeral 21 denotes a second sensor disposed below the second belt conveyor 4, and this second sensor 21 measures the entire length of the yukata 2 folded in half, which is conveyed by the first belt conveyor 3 and the second belt conveyor 4. Measure. Reference numeral 8 denotes a third belt conveyor whose starting end faces the terminal end of the second belt conveyor 4 and is arranged diagonally. Reference numeral 7 denotes a second folding knife as a sheet and yukata folding device disposed opposite to the gap between the end of the second belt conveyor 4 and the start of the third belt conveyor 8; The folding knife 7 is constructed so that the folded yukata 2 hangs down from the end of the second belt conveyor 4, and when it reaches 1/2 of its total length, the folding knife is activated. A fourth belt conveyor 9 is disposed horizontally with its starting end facing the terminal end of the third belt conveyor 8.

Next, the operation of the sheet and yukata folding machine described above will be explained.

First, the yukata 2 ironed by the roll iron 1 is automatically and continuously sent from the delivery port 1A of the roll iron 1 to the first belt conveyor 3 of the sheet and yukata folding machine. The entire length of the yukata 2 sent onto the first belt conveyor 3 is measured by the first sensor 20 and hangs down from the end of the first belt conveyor 3. When the sagging reaches 1/2 of the total length of the yukata 2, the first folding knife 5 is activated, and the yukata 2 is folded at 1/2 of the total length by the knife 5. The yukata 2 is pushed into the opening between the first belt conveyor 3 and the second belt conveyor 4, and subsequently, due to the conveying action of the first belt conveyor 3 and the second belt conveyor 4, the yukata 2 is The folded portion is drawn between the first belt conveyor 3 and the second belt conveyor 4 and folded into two.

The length of the yukata that has been folded in half is measured again by the second sensor 21, and the yukata is hung at the end of the second belt conveyor 4. When the hanging reaches 1/4 of the total length of the yukata 2, the second folding knife 7 is activated, and the yukata 2 is folded at 1/4 of the total length by the knife 7, and then The bent portion is pushed into the opening between the second belt conveyor 4 and the third belt conveyor 8, and subsequently, by the conveying action of the second belt conveyor 4 and the third belt conveyor 8, Yukata 2 is folded into four. Then, it is transferred from the third belt conveyor 8 to the fourth belt conveyor 9 and discharged to the outlet.

In the above explanation, the first sensor 20 measures the total length of the sheet or yukata, and the second sensor 21 measures 1/2 the length, but by adding a device with a calculation function, , these sensors can also be combined into one. In other words, the total length of the sheet or yukata is measured with a sensor, then introduced into a calculation device to calculate the 1/2 point and 1/4 point, and the respective outputs are used to select the first folding knife and the second folding knife. It can also activate knives.

[Problem that the invention attempts to solve]

In this way, the body part of the yukata is folded in two and then in four, but whether it is folded in two or in four, the tip part hangs down and then hangs down, as shown in Figure 5. This is not a problem for sheets, because the part that is caught between the belt conveyors is pulled between the upper and lower belt conveyors, but in the case of a yukata, the ends of the sleeves that hang down are pulled. The problem is that it bends into a triangular shape.

This invention improves the above-mentioned problems, and the sleeve part does not bend into a triangular shape, but has the correct shape.
It is an object of the present invention to provide sheets that can be folded into three or four, and a device for preventing folding of a yukata sleeve in a yukata folding machine.

[Means for solving problems]

In order to achieve the above object, the present invention provides a sheet and yukata folding machine that folds sheets in half by inserting a folding knife into the opening of the pair of upper and lower belt conveyors. An air nozzle is installed diagonally above the opening of the yukata to press the sleeves of the yukata toward the upper belt conveyor. It is characterized by being configured to be inserted into the occlusal opening while being stuck to the upper belt conveyor.

[Effect]

When air is blown from the air nozzle in conjunction with the operation of the folding knife, the blowing force keeps the sleeve part stuck to the belt conveyor and is inserted into the bite opening, so that the sleeve part is It does not bend into a triangular shape.

〔Example〕

Hereinafter, an example of the implementation of the present invention will be explained based on FIGS. 1 to 3.

In FIGS. 1 to 3, reference numerals 1 to 5 and 7 to 9, as well as 20 and 21, indicate the same parts as those described as the conventional example in FIGS. 4 and 5.

In the present invention, air nozzles 6 are disposed diagonally above the terminal end of the first belt conveyor 3 and the starting end of the second belt conveyor 4 to press at least both ends of the sleeves of the yukata toward the belt conveyor. Air nozzles 6' are disposed diagonally above the terminal end of the second belt conveyor 4 and the starting end of the third belt conveyor 8 to press at least both ends of the sleeves of the yukata towards the belt conveyor, and the air nozzles 6, 6' It is configured to operate in conjunction with the operations of the first folding knife 5 and the second folding knife 7.

In this way, the sleeves of the yukata are kept stuck to the belt conveyor by air blowing, and the sleeves of the yukata are kept stuck to the belt conveyor while the first belt conveyor 3 and the second belt conveyor 4, or the second belt conveyor 4 and the third belt conveyor 8 It is inserted into the occlusal opening of the sleeve and can be folded in two or four while maintaining the correct shape without bending the sleeve into a triangular shape.

[Effect of idea]

As described above, according to the present invention, when folding a yukata using a sheet folding machine, the sleeves of the yukata can be folded in two or four while maintaining the correct shape without being bent into a triangular shape. .
