Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a weft alignment device for toweling cloth, etc. in a manufacturing apparatus for towels, sheets, etc.

For example, when manufacturing towels, a long strip of towel fabric is cut to an appropriate length, both ends of the cut towel fabric are folded into three, and the three folded parts are sewn to finish the process. Unlike paper or wood, terry cloth has no stiffness and is easily deformed, especially when the weft threads are meandering. Therefore, if you simply cut the toweling material, the weft threads will be cut and the weft threads at both ends of the toweling material will become frayed, or even if you sew the towel material, ``hanging'' will occur as you use it, causing it to become diamond-shaped. Problems such as deformation occur.

An example of a device that solves this problem is disclosed in Japanese Patent No. 80603. The outline of this device will be described based on FIGS. 1 to 4. That is, from the pre-cutting state shown in FIG. 1, the sliding frame 124 is first rotated downward as shown in FIG. If it does, then the sliding frame 124 is rotated upward to engage the no-lattice portion 105 with the U-shaped wire 110 as shown in FIG. What is important here is that the lower end of the fabric 104 is simply hanging down, there is nothing to pull it downwards, and the fabric 104 is light and easy to shake, so the non-woven part 105 is connected to the U-shaped wire 110 as described above. Even if you try to engage it, it is difficult to do so. In addition, since the wire 110 is U-shaped and the base is not constricted, even if the wire 110
Even if the weftless portion 105 engages with the wire 110, when the fabric 104 is pulled upward, the weftless portion 105 engages with the wire 110.
It is easy to fall off. Further, the wedge material 152 is for supporting and folding the cut fabric 104, and the weftless portion 105 does not apply tension to the fabric 104 when engaged with the wire 110. In addition, after cutting the longitudinal edge 132, the sliding frame 1
When the sliding frame 12 is rotated upward,
This prevents the fabric 104 from being pulled up by the wire 11.
It does not apply tension to the fabric 104 when engaged. Therefore, as shown in Figure 4,
Fabric 104 is made of movable cutter 115 and fixed cutter 107.
When cutting the wire 110, there is a non-latitude portion 105
This means that the portion where the threads are not engaged will not be cut along the weft thread.

Therefore, the present invention provides a device for aligning the weft threads of towel cloth, etc. in the manufacturing equipment for towels, etc., which solves this problem.The feature is that the weft threads are not present at intervals along the longitudinal direction. An apparatus for producing towels, etc., which pulls out a piece of toweling fabric, etc., has a terry cloth, cuts it into an appropriate length, folds both ends of the cut towel fabric, etc. into three, and sews the three-folded part, which pulls out the towel fabric, etc. A comb tooth for weft alignment consisting of a large number of protrusions provided at appropriately small intervals along a direction perpendicular to the direction of pulling out the toweling material, etc. is provided at a position immediately above the cutting point of the toweling material, etc. on the mounting table on which the toweling material is placed. A lifting plate is disposed in a recess formed above the comb teeth of the mounting table, is rotatable around a horizontal axis, and has its upper surface flush with the upper surface of the mounting table in a horizontal state. , a rotating means for rotating the lifting plate around a horizontal axis is provided, a mounting plate for weights such as terry cloth is arranged on the lifting plate, and the lifting plate and the mounting plate are rotated upward by the rotating means. After gripping the end of the toweling cloth or the like sandwiched between the plates, a pull-out device is provided which pulls out the toweling cloth by rubbing it against the comb teeth and engages the section of the toweling cloth with no weft threads with the comb teeth. Each protrusion of the tooth is formed so that its upper end protrudes further than its lower end.

According to this configuration, the section without weft threads is reliably engaged with the comb teeth by the synergistic action of the pull-out device, the mounting plate, and the upper end of the protruding upper side of the comb teeth, and the section without the engaged weft threads is reliably engaged with the comb teeth. The section does not come off the comb teeth. That is, when the towel fabric or the like is forcibly pulled out by the pull-out device, the mounting plate applies an appropriate weight to the towel fabric or the like. Therefore, the terry cloth or the like is pulled out by rubbing the comb teeth while being appropriately tensioned by the weight of the mounting plate. Therefore, when the weft-free section is placed above the comb teeth, the weft-free section is strongly engaged with the comb teeth. Furthermore, even if the section without weft threads tries to be pulled out from the comb teeth in this state, it will not come out because it will get caught on the upper end of the protruding upper side of the comb teeth. Therefore, there is not a single drop left on each protrusion of the comb teeth. The weft threads are aligned in a straight line. When the cutter is lowered from this state and cut, the toweling fabric or the like is accurately cut along the weft.

An embodiment of the present invention will be described below with reference to FIG. 5 and subsequent figures.

Although the above embodiment describes a towel manufacturing apparatus, the present invention is not limited thereto, and can also be applied to fabrics such as sheets.

As described above, according to the weft alignment device for towel fabric, etc. in the towel manufacturing apparatus of the present invention, the section with no weft threads is produced by the synergistic action of the pull-out device, the mounting plate, and the upper end of the protruding upper side of the comb teeth. It is capable of being reliably engaged with the comb teeth, and the engaged section without weft threads does not come off from the comb teeth. That is, when the towel fabric or the like is forcibly pulled out by the pull-out device, the mounting plate applies an appropriate weight to the towel fabric or the like. Therefore, the terry cloth or the like is pulled out by rubbing the comb teeth while being appropriately tensioned by the weight of the mounting plate. Therefore, when the section without weft threads is above the comb teeth,
For strength, the weft-free section is brought into engagement with the comb teeth. Furthermore, even if the section without weft threads tries to come out from the comb teeth in this state, it will not come out because it gets caught on the upper end of the protruding upper side of the comb teeth. Therefore, the weft threads can be aligned in a straight line without missing a single drop for each protrusion of the comb teeth. When the cutter is lowered from this state and cut, the toweling fabric or the like is accurately cut along the weft.
