Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to a paper spreading machine, which guides and feeds long circular knit bags to a feeding device so that they can be spread neatly while highlighting them. Regarding the tenting frame to be sent.

(Prior Art) This type of conventional tenting frame is held directly on a pair of feeding rollers 41, 42 via rollers 43, 43, as shown in FIG. 4, and is guided from the outside on both sides. A structure was adopted in which the positions of left and right rulers 47, 48 were regulated by rollers 45, 46.

(Problems to be Solved by the Invention) However, in the conventional tenting frame 40 described above, the rollers 41 and 42 for feeding are directly mounted, and the trochanters 43 and 4 are located very close to these rollers 41 and 42.
3, the bag 9 bulges at the trochanter 43, 43 just before the rollers 41, 42, and the bag 9, which has been neatly guided by the upper rulers 47, 48, is caused by these bulges. It had the problem of being disarrayed and wrinkled.

The present invention was devised in view of the above, and the holding trochanter of the tentering frame is moved upward and held by an auxiliary roller, and a tentering guide ruler is extended below the trochanter. In particular, it is an object of the present invention to provide a tentering frame for a paper spreading machine that guides the finishing to a feeding roller with neatly aligned edges.

(Means for Solving the Problems) The means of the present invention for achieving the above object is shown in FIGS. 1 to 3 of the corresponding drawings of the embodiments. A pair of rollers 3 for feeding out the traveling body 2 that reciprocates on the spreading table 1a.
A pair of auxiliary rollers 4a, which are rotated in the same direction as the rollers 3a, 3b above the rollers 3a, 3b.
The trochanters 11, 11 are held by the guide portions 5, 6 of 4b with movement in the longitudinal direction of the auxiliary rollers regulated.
The trochanters 11, 11 are connected to the upper windows 12, 12.
a pair of left and right tentering rulers 13, 14 which are rotatably supported on the window portions 12, 12, and which are connected on the outside of the windows 12, 12 and have a sufficient guide length from the top to the bottom, especially in the downward direction; This is a tentering frame for a spreader, characterized in that it is comprised of a connecting member 15 that fixedly connects rulers 13 and 14 in a width-adjustable manner.

(Function) The function of the present invention described above is such that the tentering frame 10 is connected to the auxiliary rollers 4a, 4b above the feeding rollers 3a, 3b.
The trochanter 1 is held vertically and horizontally by the guide portions 5 and 6 via the trochanters 11, 11, and the trochanter 1
From 1 and 11, extend the width of the ruler 1 to a sufficient length downwards.
3 and 14 are extended, the feeding roller 3
The bag 9 is bulged by a trochanter just before the rollers 3a and 3b, effectively preventing the bag 9 from becoming disordered, and guiding the bag 9 to a pair of rollers 3a and 3b for delivery with the bag 9 neatly aligned.

(Example) Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

In FIGS. 1 to 3, the tenter frame in the spreading machine of this embodiment is the one used in the spreading machine 1 for spreading long circular knitted bags 9 such as cylindrical stockinette or knitwear. A pair of auxiliary rollers 4a, 4b, which are driven to rotate in the same direction as the rollers 3a, 3b, are guided above the pair of rollers 3a, 3b for feeding out the traveling main body 2, which reciprocate on the spreading table 1a. The trochanters 11, 11 are held by the portions 5, 6 with movement in the longitudinal direction of the auxiliary rollers regulated, and the trochanters 1
1 and 11 are rotatably supported on upper window parts 12 and 12, and are connected on the outside of the window parts 12 and 12, and have a sufficient guide length from the upper part to the lower part, especially in the lower part. width ruler 13,1
4, and a connecting member 15 that fixedly connects the tentering rulers 13 and 14 so that the width dimension can be adjusted.

The traveling main body 2 runs along the bag 9 in the longitudinal direction of the spreading table 1a.
The bag 9 is fed from above by the rotation of the feeding rollers 3a and 3b as shown by the arrows C and D. When cutting the sheets by feeding them onto the spreading table 1a in synchronization with the reciprocating movement, the cutting device 7 cuts or folds the sheets at each end and stacks them one by one. The level of the supported elevating frame 2a is adjusted by elevating means 8.

The auxiliary rollers 4a, 4b are the feeding rollers 3a,
3b is rotatably supported by supports 2b and 2d erected on the lifting frame 2a, and is rotated in the same direction as the feeding rollers 3a and 3b (arrows c and d) and are rotated at the same circumferential speed by one delivery roller 3b via a transmission means 8c. The rollers 3a..., 4b can have a clamping interval that can be adjusted according to the thickness of the bag 9, and can be biased by a spring or the like, and the gears 8a, 8
It goes without saying that instead of b, double-sided toothed belts, pulleys, etc. can be individually rotated in the directions of arrows c and d.

A pair of left and right guide portions 5, 6 are formed on the auxiliary rollers 4a, 4b. The guide portion 6 of the other roller 4b is constituted by a sleeve fixed opposite to the collar spacing portion.

The width adjustment ruler 13 on the left side of one side of the width adjustment frame 10
The upper end thereof is curved to the right, and a window portion 12 with a connecting rail 13b projecting inward is integrally formed inside the lower end of the curved portion. straight outer edge 1
3a forms a tapered edge. The other right tentering ruler 14 has an upper end curved to the left, and a connecting ruler 14b is provided inwardly protruding perpendicularly below the curved portion. Straight outer edge 14
A is an edge tapered outward. These left and right width rulers 13 and 14 extend downward from the windows 12 and 12 to just before the delivery rollers 3a and 3b, and width the bag 9 using the outer edges 13a and 14b.

The connecting member 15 is a connecting rail 15 that overlaps the upper part of the left connecting rail 13b and slides on the left side connecting rail 13b.
a, a groove-shaped guide 15b that is integrally formed at the lower end of the window portion 12 that is integrally connected to the right end of the rail 15a, and that slidably receives the right connecting rail 14b, and the rail 13b. , 15a, and a fastening part 15d, the width of which can be adjusted in accordance with the width of the bag 9.

The trochanters 11 provided in each window section 12 include a support shaft 11a which is horizontally fixed at both ends in a square shape with an eccentric part in the center, and three trochanters rotatably supported on each part of the support shaft 11a. trochanteric bodies 11b, 11c, 1
1d, one auxiliary roller 4
The movement in the left-right axis direction is restricted between the collars 5a and 5b of a, and at the same time, the collars 5a and 5b are
b and the sleeve 6 of the other auxiliary roller 4b hold the frame 10 in the up and down vertical direction, and hold the tenter frame 10 that has been inserted into the bag 9 in a suspended state.

The tentering frame 10 having the above configuration has an upper trochanter 1
The feeding rollers 3a, 3 are suspended from the auxiliary rollers 4a, 4b by 1, 11 inside the bag 9.
The relatively long edges 13a, 14a of the width-setting rulers 13, 14 leading to the edges 14b allow the bag 9 to be neatly sharpened without any distortion and placed on the feeding rollers 3a, 3b.
to guide you.

(Effect of the invention) As described above, according to the tentering frame 10 in the spreading machine of the invention, the frame 10
The trochanter 1 is moved vertically and horizontally by the guide portions 5 and 6 of the auxiliary rollers 4a and 4b above the rollers a and 3b.

Since the rollers 3 and 14 are extended, the feeding roller 3
The bag 9 is inflated by the trochanter just before points a and 3b,
It is possible to effectively prevent the sharpening from being disordered, and it is possible to guide the sharpening to the delivery rollers 3a, 3b while neatly aligning the sharpening.
