Abstract

PURPOSE:To provide the subject apparatus having a specified constitution where a string is fed in a loosened state and capable of loosely tying in a loosened state without tightly tying in a tensioned state of the string in a tying process where an edible string is tied around a food such as SHINODAMAKI [chicken, fish and vegetable mixture wrapped up in bag of fried bean curd and tied with KAMPYO (long, tape-like shavings of dry gourd)]. CONSTITUTION:The string-holding part of a send roller 2 is initially pressed by a string-pressing mechanism 1 and a string (S1) between the roller 2 and an upper stream guide roller 3 is loosened and retained by a length corresponding to that required for tying around a material to be bundled using the first loosening formation unit 4. A loosened string (S2) between the roller 2 and a down stream guide roller 5 is simultaneously fed to mutually bind each end part of the string tied around the material to be bundled. Pressing on the holding part of the roller 2 is then dissolved arid the second loosening formation unit 6 is operated at the same time so that the string (S2) between the respective rollers 2 and 5 may be loosened and retained by a length required for mutually binding each end part of the string after completion of tying around the material to be bundled. The first loosened string (S1) is further fed in this state for tying around the material to be bundled.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) This invention provides an automatic tying machine for tying and processing foods such as kinchaku konbu-maki, Shinada-maki, meat-maki, etc. with edible strings or ribbons. Regarding the device for supplying a string to a binding mechanism, more specifically, when stringing an object to be tied, the edible string or ribbon can be loosely hung in a relaxed state without being tied in a tensioned state. This invention relates to a string supply device.

(Prior Art) Conventionally known automatic tying machines are of a type in which a predetermined tension is applied to the string and the object to be tied is tied with the string.

Japanese Patent Application Laid-open No. 60-203149 discloses an edible string made of collagen or a natural polymeric substance based on collagen.

(Problems to be Solved by the Invention) Since the edible string is made of a material that is digestible and absorbable, it tends to lack strength compared to ordinary strings, and also tends to lack flexibility when dry. It has properties.

Therefore, when such edible strings are fed into a conventional automatic tying machine, the lanyards may not be able to withstand the tension of time, resulting in scratches or cuts, or the knots may come undone after tying, resulting in a stable tying. Cannot be processed.

As a specific example, when kelp is bound with edible collagen ribbons and then boiled to make kelp rolls, firstly, the collagen ribbons during the binding process lack strength and flexibility. Due to the predetermined tension being applied under such conditions, it is easy to cause cuts and scratches, resulting in poor binding.Next, collagen ribbons with collagen ribbons that are free from such cuts and scratches, or have completed the binding process with only small scratches. When kelp is boiled, the volume of kelp expands to about 4 times, while the collagen ribbon shrinks by about 30% due to heat. The scratches left during the binding process will expand and cause cuts, causing the kelp rolls to fall apart.

SUMMARY OF THE INVENTION It is an object of the present invention to overcome the above-mentioned disadvantages and to provide a device for feeding edible strings into a conventionally known automatic stringing system without the risk of damage or breakage.

(Means for Solving the Problems) In order to achieve the above object, the present invention provides the following configuration. That is, a feed roller with a string pressing mechanism is provided on the supply path of the string, a first slack forming means is arranged upstream of the feed roller, and a second slack forming means is arranged downstream of the feed roller. In the first relaxation forming means,
A string of a length corresponding to the length of the string can be stored in a relaxed state when the string is tied to the object to be tied, and the second slack forming means can tie both ends of the string after the string is tied to the object to be tied. A length of string can be stored in a relaxed manner.

As the string holding mechanism, a first fluid actuator including a rod that can be pressed against a string hooking portion of the feed roller;
Nipping rollers are used.

The first relaxation forming means has an oscillating roller interposed between the feed roller and a guide roller upstream thereof, and a driving means for angularly displacing the oscillating roller. It is effective to provide a string holding means that constantly presses the parts.

The driving means transmits rotational driving force from the crank to an arm via a link, and the swinging roller is attached to the free end of the arm.

The strap pressing means uses a brake shoe that can be pressed at all times to the strap hook of the swinging roller, for example, a strap whose end is fixedly supported and a weight is attached to the other end.

The second relaxation forming means interposes an idle roller between the feed roller and a downstream guide roller,
A second fluid actuator is provided for displacing the idle roller in a direction perpendicular to the running direction of the string.

In addition, a means for wetting the string, for example, a liquid spray nozzle, is provided at the most upstream position of the string supply path, and a container containing a soft material that is brought into close contact with the edge is provided directly below the wetting means for the string.

(Function) First, the first fluid actuator is activated, and the tip of its rod presses down on the feed roller's strapping part, while the rod of the second fluid actuator is displaced backward, causing the idle roller to press down. (See Figure 3).

Under that condition, when the rotation of the crank of the first relaxation forming means is transmitted to the arm via the link and the swinging roller attached to the free end of the arm undergoes an angular displacement, the string will move around the swinging roller. Due to the angular displacement, it is let out from the upstream (see the solid line position in Figure 3), and then, when the swinging roller returns to its original position, the part of the string that has been let out relaxes downward (first relaxation), and its relaxed length corresponds to the length of the string attached to the object to be bound (see the position of the two-dot chain line in Fig. 3).

Furthermore, under the above conditions, the loosening of the string that occurs between the feed roller and the guide roller provided downstream thereof (second loosening, see the solid line position in Figure 3) causes the string to be attached to the object to be tied after completion. It is fed out and consumed to be used for binding both ends of the string (see the position of the two-dot chain line in Figure 3).

Next, the second fluid actuator is actuated to displace the idle roller forward, while the rod of the first fluid actuator is retracted, and the feed roller's strap releases its hold (the first (see figure).

As a result of this action, a slack (second slack) in the string is created between the feed roller and the guide roller provided downstream thereof (see FIG. 1).

Furthermore, while maintaining the formation of the second relaxation, the first
The slack is fed out and consumed in order to be used for stringing the object to be bound (see Figure 2).

The above operation is repeated.

The moisture sprayed from the liquid spray nozzle toward the string is evenly applied to the entire string as it passes through the container containing the soft material, creating a pliability that can be easily applied afterwards. It is easy to process, ie, tie and tie, and is less likely to be cut or damaged.

(Example) Embodiments of the invention will be described in detail based on the drawings.

FIG. 1 to FIG. 4 show an embodiment of a string supplying device according to the present invention, and the string supplying device includes a feed roller 2 provided with a string pressing mechanism 1 on a supplying path of the string S. A first slack forming means 4 is provided between the feed roller 2 and a guide roller 3 provided upstream thereof, and a second slack forming means 6 is provided between the feed roller 2 and a guide roller 5 provided downstream thereof. Furthermore, a string wetting means 7 is provided at the most upstream position of the string S supply path.

The string presser mechanism 1 includes a first fluid actuator 11 equipped with a rod lla that can be pressed against the string hook portion of the feed roller 2.

It is also conceivable to use a nipping roller (not shown) which can be press-contacted to the string hanging portion of the feed roller 2 as the string holding mechanism.

The first relaxation forming means 4 has a swinging roller 41 interposed between the feed roller 2 and the guide roller 3 upstream thereof, and serves as a drive means 42 for angularly displacing the swinging roller 41, and is rotatably driven by a crank 42a. A force is transmitted to the arm 42c via the link 42b, and a swinging roller 41 is attached to the free end of the arm 42c, while a string holding means is provided that constantly presses the strap of the swinging roller 41. 43 is a brake shoe 4 made of a band leather fixedly supported at one end and having a weight 43 attached to the other end.
3b.

The second slack forming means 6 includes an idle roller 61 interposed between the feed roller 2 and the guide roller 5 downstream thereof, and a second slack forming means 6 that displaces the idle roller 61 in a direction perpendicular to the running direction of the string S. A fluid actuator 62 is provided.

The string wetting means 7 includes a liquid spray nozzle 71 and a container 7 attached directly below the liquid spray nozzle 71 containing a soft material 72 that comes into close contact with the string S.
3.

The string wetting means 7 according to this embodiment connects the compressed air supply pipe 71a and the liquid supply pipe 71b to the liquid spray nozzle 71, and the soft material 72 has a notch 72a (through which the string S can pass). (see Figure 4).

In the first slack forming means 4 of the string supply device according to this embodiment,
To tie the string to the object to be tied (not shown), a string S of a length corresponding to the length is relaxed and stored to form a first slack S1 (see FIG. 1). After the stringing to the bundle is completed, the string S of the length required for binding both ends of the string, that is, forming a knot of the string, is relaxed and stored, and then the second loosening S is performed.
2 (see Figure 3).

When supplying the string S using the string supplying device according to the present embodiment, first, the first fluid actuator 11 is activated, and the tip of the rod ILa presses down the string hooking section of the feed roller 2. , the rod 62a of the second fluid actuator 62 is displaced backward, causing the idle roller 61 to retreat (see FIG. 3).

Under this condition, the crank 4 of the first relaxation forming means 4
The rotation of 2a is transmitted to the arm 42C via the link 42b, and the swinging roller 41 attached to the free end of the arm 42c is angularly displaced.

Then, the string S is let out from the upstream along with the angular displacement of the swinging roller 41 (see the solid line position in FIG. 3), and then,
When the swinging roller 41 returns to its original position, the part of the string S that has been let out relaxes downward to form a first slack Sl, whose loosened length corresponds to the length of the cord hooked onto the object to be bound. (3rd
(See the position of the two-dot chain line in the figure).

Furthermore, under the above conditions, the second relaxation S2 of the string S (see the solid line position in FIG. 3), which occurs between the feed roller 2 and the guide roller 5 provided downstream thereof, prevents the string from hanging on the object to be bound. It is fed out and consumed to be used for binding both ends of the string S after completion (see the position shown by the two-dot chain line in FIG. 3).

Next, the second fluid actuator 62 is actuated to displace the idle roller 61 forward, while the first fluid actuator 11
The rod lla moves back, and the strap of the feed roller 2 releases its hold (see FIG. 1).

This action creates a second slack S2 of the string S between the feed roller 2 and the guide roller 5 provided downstream thereof (see FIG. 1).

Furthermore, while maintaining the formation of the second slack S2, the first slack S1 is drawn out and consumed for use in stringing the object to be tied (see FIG. 2).

The above operation is repeated to supply the string S to the automatic stringing machine.

Note that the first relaxation forming means 4 according to this embodiment is, for example,
By moving the position of the connection point between the arm 42c and the link 42b in the longitudinal direction of the arm 42c and adjusting the amount of angular displacement of the swinging roller 41, the first relaxation S that stores the relaxation
The length of the second relaxation S2 can be set arbitrarily, and the second relaxation forming means 6 adjusts the length of the second relaxation S2 to which relaxation is stored by adjusting the operating stroke of the second fluid actuator 62. It is possible to set the value arbitrarily.

On the other hand, the string wetting means 7 provided at the most upstream side of the string S supply path
First, for example, a liquid such as water and compressed air are mixed and sprayed toward the string S from the liquid spray nozzle 71.

After that, when the string S passes through the notch 72a of the soft material 72 housed in the container 73, the moisture attached to the string S is evenly applied to the entire string S, and the string S becomes uniformly pliable. .

The string S that has passed through the string wetting means 7 passes through the first relaxation forming means 4 and the second relaxation forming means 6 and is consumed for hanging and binding, but the string S that has become pliable is used for hanging and binding. This makes bundling easier, and cuts and scratches are less likely to occur.

(Effects of the Invention) As described in detail above, the string supply device in the automatic stringing machine according to the present invention stores edible strings or ribbons that are relaxed and stored using the first relaxation forming means and the second relaxation forming means. Since it is supplied to an automatic tying machine, it is possible to tie the string to the object to be tied loosely in a relaxed state, and when tying both ends of the string S after the tying is completed, there is no need to put too much stress on the string. It becomes possible to form a knot without applying tension.

Therefore, since no unreasonable force is applied to the string, the risk of damage or breakage to the string and the string during binding is greatly reduced.

In addition, if a string moistening means is provided at the most upstream side of the string supply path, the string will become moist and pliable, and then the string will be hooked and tied in a relaxed state, so there is a risk that the string will be damaged or cut. Not only is this further reduced, but when pliable strings are tied, a strong knot can be obtained, which prevents the strings from coming undone after tying.

Furthermore, since the strings are loosely hung on the objects bound by the automatic stringing machine equipped with the string supply device according to the present invention, even if the objects are overheated by boiling, etc. There is enough room for the expansion of the binding body or the heat contraction of the string, so that the objects to be bound will not deform into a distorted shape or the objects will not come apart due to the string breaking.
