[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for producing a long bar-shaped sausage or the like, and more specifically, a casing mounted on a filling nozzle is continuously filled with a filling material to obtain a long piece of sausage. The present invention relates to a method and a device for producing rod-shaped sausage and the like.

2. Description of the Related Art Certain products such as sausages are packed into a long stick in a natural casing such as sheep intestine or pig intestine or an artificial casing such as cellulose casing or collagen casing. It is manufactured by "straight filling".

Conventionally, it has been the current situation that straight filling is performed using the following manufacturing apparatus. (JP-A-5
That is, a filling material such as a product in the form of granules or paste is contained in a cylindrical hydraulic stuffer or air stuffer, and the filling material is sent to a stuffer nozzle by a delivery piston. A casing is manually attached to the stuffer nozzle, and the filling material is continuously fed into the casing from the tip of the stuffer nozzle at a constant pressure and a fixed amount.

The casing is pulled out from the stuffer nozzle as the filling is filled into the casing from the tip of the stuffer nozzle. At this time, an operator adjusts the drawing speed by manually braking the casing mounted on the filling nozzle to obtain a product with a predetermined filling degree.

On the other hand, the straight filling method and apparatus disclosed in JP-A-58-73508 are as follows. That is, a conveyor device is provided which is composed of flat belts having running portions facing each other in the vertical direction at intervals, and a filled casing deformed into an elliptical cross-sectional shape across the running portions of the conveyor device,
By the conveyer device, it is conveyed in a direction away from the nozzle.

The straight-filled product obtained by the above-mentioned filling operation is processed, for example, as follows. First, the obtained straight-filled product is heat-treated and dried, and then cut into a fixed size (for example, 150 mm) to obtain a salami product (beef stick). The other one is straight filling, then twisting to a fixed size to make a link-shaped sausage, which is then frozen to obtain raw sausage.

A filling pump mechanism using a vane pump may be used in place of the above-mentioned filling pump mechanism by the stuffer. Here, a filling pump mechanism using a vane pump is known. (JP-A-3-18939
(See No. 1)

[0008]

However, the straight filling according to the prior art described above has the following problems. Generally, when a hard packing is used or the packing is smaller than the standard packing diameter of the casing, there are the following problems. That is, when the casing is being filled with the filling material, air may be entrained in the filling material through the gap between the nozzle and the casing, resulting in the production of a product in which air bubbles are mixed. In the salami product made of a hard filling material, or in the product which is straightly filled with a soft filling material and then linked, there is a particular demand for elimination of the bubbles.

The filler discharged from the tip of the nozzle into the casing exerts a force on the casing in the direction of pulling out from the nozzle and a force in the direction of expanding the diameter of the casing. In manual straight filling of the artificial casing, the braking force applied to the casing by the operator's hand is not constant, so the force acting on the casing in the direction of pulling out from the nozzle and the force acting in the direction of expanding the diameter of the casing are It is not constant. Therefore, the diameter of the casing filled with the filler is not uniform. Furthermore, in addition to this, the expansion resistance of one casing may not always be constant in the longitudinal direction, which promotes variation in the expansion amount of the casing,
The diameters of the filled casings are not uniform because the portions of one casing vary.

Further, in the straight filling method and apparatus disclosed in the above-mentioned Japanese Patent Laid-Open No. 58-73508, straight filling is performed for an artificial casing, but the cross-sectional shape of the filled casing covers the entire area between the running parts. Since they have the same elliptical shape, particularly in a straight filling product having a low filling pressure, slippage is likely to occur with the conveyor device, and the diameter of the filled casing is difficult to be uniform. In straight filling of a natural intestine casing by hand, in order to make uniform the filling degree (filling pressure) of each portion of one natural intestine having a variation in diameter over its entire length,
The worker performs the filling work while adjusting the casing braking force by hand. Natural intestinal straight filling products have large variations in filling diameter, and the filling weight per unit length is not uniform. Excess amount of the actual product weight against the set weight (sales)
Increases, and the product cost increases accordingly.

Further, in the conventionally known straight filling apparatus, there are many work steps that depend on human labor, the productivity is poor, and the product cost becomes high. When it is desired to manually sell a conventionally known straight-filled product of natural intestine casing (a product in which the filling diameters of the parts are largely different), the production is limited to a skilled filling operator, and the product cost is increased. SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a method and apparatus for improving the above-mentioned drawbacks of the known straight filling and performing automatic mechanical straight filling.

In FIG. 4A, the sandwiching plates 11 are provided at positions opposite to each other at opposite positions. However, as shown in FIG. 4B, the sandwiching plates 11 are
The structure may be provided at the same position in the facing position. 4A and 4B,
The carrier device 7 causes the straight-filled casing 4c to have a reduced diameter portion and an enlarged diameter portion in the longitudinal direction thereof.

Now, when the filling of the casing 4 by the filling nozzle 3 is completed, the filling pump 1 must be stopped. An apparatus for detecting the end of the straight filling of the casing 4 will be described below with reference to FIG.

The floodlight 1 is provided on both sides of the rear end of the casing 4 on the filling nozzle 3 which is being filled with the filling.
2a and a light receiver 12b are provided. Floodlight 12a
And the light receiver 12b constitutes the optical sensor 12A. A bracket 12c is provided on the cabinet 101 so that its position can be adjusted in the longitudinal direction of the filling nozzle 3, and the optical sensor 12A is mounted on the bracket 12c. Then, the light projector 12a and the light receiver 12
The b and the bracket 12c constitute the detecting means 12. The position of the line P (optical axis) connecting the light projector 12a and the light receiver 12b is located at the rear end portion of the casing 4 which is attached to the filling nozzle 3 and hangs downward from the filling nozzle 3.
(See FIGS. 2, 5, and 8.)

The bracket 12c is movably guided by the guide 102a. To change the mounting position of the bracket 12c, the bracket 12c is moved to the guide 102a.
It is moved by a and fixed by the set screw 12e.

In the illustrated state, the light from the projector 12a is blocked by the contracted portion 4a of the casing 4 which is compressed in a bellows shape, and does not reach the light receiver 12b. In this state, since the casing 4 still remains in the filling nozzle 3 for a sufficient length, the filling material is continuously discharged from the filling nozzle 3.

Now, when all the contracted portions 4a of the casing 4 mounted on the filling nozzle 3 are sent out to form only one sheet portion 4b of the casing 4, the light from the projector 12a is received by the light receiver 1a.
2b is reached, and the completion of filling the casing 4 is detected. The light receiver 12b is the filling pump 1
A signal is transmitted to a motor (not shown) for driving the filling pump 1 to stop the operation of the filling pump 1. By stopping the motor with the signal from the light receiver 12b via the timer, the filling can be filled up to the rear end position of the casing 4.

In the above description, the transmissive photoelectric sensor 12A including the light projector 12a and the light receiver 12b may be replaced with another known sensor such as a reflective sensor or an electrostatic sensor. Further, the detection of the completion of the filling is limited to the one that is detected when the optical axis P is blocked by the bellows portion of the casing 4 near the rear end as described above and the light can be transmitted by the single casing. It does not include the case where the casing disappears from the bellows state or the state where the casing disappears from the state of one casing, and detects the morphological change of the rear end of these casings. It includes all other detection means.

In order to reliably detect the contracted portion 4a at the rear end of the casing 4 mounted on the filling nozzle 3, the positioning member 5 is prevented from separating from the positioning member 5 during filling so that the contracted portion 4a does not separate from the positioning member 5. A pressing member 13 as a separation preventing member for pressing the contracted portion 4a at the rear end portion against the filling nozzle 3 is provided.

In the illustrated embodiment, the pressing member 13 is cantilevered by the pin 14 and has a structure for pressing the casing 4 against the filling nozzle 3 by its own weight. A suitable pressing structure, such as a structure for pressing against 3, can be used.

The separation preventing member may have a structure in which the casing 4 is pressed against the positioning member 5, and the purpose is to hold the rear end portion of the casing 4 until the end of filling.

Subsequently, if the casing 4 is broken during filling with the filling material, the filling nozzle 3
A mechanism for stopping the filling from will be described. First,
An apparatus for detecting breakage of the casing 4 will be described with reference to FIGS. 6 and 7.

The casing 4, which is compressed and attached to the filling nozzle 3 in a bellows shape, is pulled from the tip of the filling nozzle 3 to the one-piece portion 4b sequentially from the front of the contracted portion 4a as the filling material is filled. Will be issued. In order to detect the pulled-out state of the casing 4, the one-piece portion 4b of the casing 4 is
The rotary roller 15 that comes into contact with the rotary roller 15 is provided, and the sensor 16 that detects the rotation of the rotary roller 15 is installed. Sensor 16
A known proximity sensor, a reflection type optical sensor, or other sensor can be used. Both the rotating roller 15 and the sensor 16 constitute a detecting means for detecting the stop of the casing 4.

A concave portion 15a is formed on the outer peripheral surface of the rotary roller 15, and the filling nozzle 3 and the one-piece portion 4b of the casing 4 are inserted into the concave portion 15a. Therefore, the movement of the casing 4 pulled out from the filling nozzle 3 is reliably detected by the rotation of the rotating roller 15.

If the casing 4 breaks while the filling is being filled in the casing 4, the movement of the casing 4 is stopped and the rotation of the rotary roller 15 is stopped. Therefore, the rotating roller 1
Stopping the rotation of 5 means breaking of the casing 4. When the rotating roller 15 stops,
This is detected by the sensor 16 and the output signal thereof is given to the drive motor of the filling pump 1 to stop the discharge of the filling material by the filling pump 1.

Since the device for detecting the breakage of the casing can detect the state where the one sheet portion 4b on the filling nozzle 3 has disappeared due to the end of the filling of one casing,
This can also be used together as a filling completion detection device.

The casing 4 drawn out from the filling nozzle 3 is not preferable because it is overlapped or wrinkled. Therefore, at the tip of the filling nozzle 3, the casing 4 is always extended to one sheet, that is, one sheet portion 4b.
Is desirable. Also, fill the casing with the casing 4
Since air may enter the casing 4 through the gap between the filling nozzle 3 and the casing 4 when filling the inside, this must be prevented. Furthermore, by pulling out the casing 4, the casing 4
Is preferably extended in the longitudinal direction to reduce variations in the diameter inherent to the casing.

The elastic ring 6 as a blocking member is provided as a member for performing such an action. An elastic ring 6 according to an embodiment of the present invention will be described below with reference to FIG.

The elastic ring 6 is a donut-shaped ring made of an elastic material such as rubber or soft synthetic resin, and is formed such that the wall thickness reaching the central opening gradually becomes thinner toward the center side. Has been done. The blocking member may be made of a metal such as stainless steel as long as it achieves the above-mentioned action, and its shape is, for example, that the central opening (hole) through which the filling nozzle 3 is inserted is star-shaped. It may have irregular shaped holes such as. When filling the casing 4 with the filling material, the filling nozzle 3 is inserted through the central opening of the elastic ring 6 (the tip of the filling nozzle 3 penetrates the elastic ring 6 and projects to the outside thereof). It is set up.

As described above, the function of the elastic ring 6 is to extend the wrinkles and overlaps of the casing 4 which is attached to the filling nozzle 3 and contracts or overlaps more than two times, so that the filling nozzle is in a single state. 3 and at the same time prevents air from entering the casing 4 through the gap between the filling nozzle 3 and the casing 4, the diameter of the central opening of the elastic ring 6 is It is smaller than the outer diameter of the filling nozzle 3 (due to the braking force on the delivery of the casing 4), or equal to or slightly larger (in this case, for example, 1 mm.
The range is preferably about 2 mm to 2 mm). If the diameter of the central opening of the elastic ring 6 is extremely larger than the outer diameter of the filling nozzle 3, air may enter the casing 4 and at the same time, the filling may flow backward, and on the contrary, the elastic ring 6 The diameter of the central opening is the filling nozzle 3.
If it is extremely smaller than the outer diameter of the casing 4, it becomes difficult to pull out the casing 4.

A fixing member 81 is provided on the bracket 102, and a retaining nut 83 is provided inside the fixing member 81.
The spacer 82, the elastic ring 6 and the guide member 8 are provided. By removing the retaining nut 83 and replacing the spacer 82 with one having a different thickness, the elastic ring 6
You can change the number of attachments. Further, the position of the elastic ring 6 can be changed by changing the mounting position of the spacer 82 before and after the elastic ring 6.

The structure of the suspension device 103 will be described below. The suspension device 103 is, for example, a publicly known Japanese Patent Laid-Open No. 5-1.
Those described in JP-A-46248 and JP-A-6-7073 can be used. Here, JP-A-5-1462
A suspension device having the same configuration as that of the embodiment disclosed in Japanese Patent Publication No. 48 will be applied to the following description with reference to FIG. Suspension device 103
Is two sprockets 202, 2 that are spaced apart.
A plurality of suspension members 203 are provided on the endless traveling body 201 that is wound around 02 and travels, and the traveling route of the suspension members 203 on the horizontal plane intersects the route of the filled casing 4c discharged from the guide member 104. The locking position is fixed.

A signal generator 204 is provided which detects the amount of movement of the carrier device 7 and generates a signal whose value is proportional to the amount of movement. The signal generator 204 includes a toothed body 205 provided on the transport device 7 and a sensor 206 that detects a movement amount of the toothed body 205 and generates a pulse signal.
Based on the signal from the sensor 206, the filling casing 4c
The suspension member 203 is brought to the locking position in sequence at each time when the amount of the sheet delivered from the transport device 7 reaches a predetermined length, and the filling casing 4 is sequentially suspended by the suspension member 203 at a predetermined length.
A control device 207 that controls the motion of the endless traveling body 201 so as to suspend c is provided. The control device 207 counts the number of pulse signals generated by the signal generation device 204 and generates an output signal for each pulse number corresponding to the suspension length suspended by one suspension member 203.

And a clutch brake 210.

Since the apparatus of this embodiment comprises the stationary guide member 104 and the suspending member 203 which operates intermittently in the horizontal plane,
It has a highly reliable function even for the straight filled casing 4c, which is difficult to form a loop as compared with the linked filled casing.

The operation of the straight filling device for sausages and the like and the suspension device of the present invention configured as described above will be described. FIG. 8 shows a state before filling the casing 4 with the filling material. First, the casing 4 is attached to the filling nozzle 3, and the casing is pushed in until the rear end thereof is positioned on the positioning member 5. This work is done manually. The pressing member 13 presses the contracted portion 4 a of the casing 4 against the filling nozzle 3 after being pushed up by the casing 4.

Next, the cylinder 18 moves the filling nozzle 3 to a predetermined position where the tip of the filling nozzle 3 is inserted into the elastic ring 6. (FIG. 2) The positioning member 5 is the end surface 3 of the large diameter portion 3c of the filling nozzle 3.
It is pushed by d and moves with the filling nozzle 3. After the movement of the filling nozzle 3 is stopped, the positioning member 5 is positioned by being pressed against the stopper 12d made of an adjustable screw member attached to the bracket 12c by the extension operation of the rod 19a by starting the driving of the cylinder 19. At this position, the contracted portion 4a at the rear end of the casing 4 defined by the positioning member 5 blocks the optical axis P of the optical sensor.

The thus-moved state is shown in FIGS. 2 and 3 described above. Next, when the filling pump 1 is driven by a drive motor (not shown), the filling material is fed into the casing 4 via the filling block 2 and the filling nozzle 3. The filling nozzle 3 is divided into two parts having a large inner diameter and a small inner diameter, that is, a casing mounting portion and a filling block insertion portion, and it is possible to greatly reduce the resistance in the tube to the filling material pumped in the filling nozzle 3. The filling nozzle 3 may be a straight single tube in which the outer diameters of the casing mounting portion and the filling block insertion portion are the same. The casing 4c into which the filling has been sent is delivered to the transfer device 7 via the guide member 8. In the carrier device 7, the filled casing 4c that has been delivered is sandwiched by the sandwich plate 1
It is sandwiched by 1 and conveyed, and in this embodiment, it is passed to the suspension device 103, which is the next step, through the guide member 104 to form a loop of a predetermined length.

The operation of the suspension device 103 will be described below with reference to FIGS. 1 and 11. The carrier device 7 feeds the filled casing 4c held by the holding plate 11 attached to the chain 10 into the guide member 104 by rotating the sprocket 9 at a constant speed. The signal generator 204 outputs a pulse signal proportional to the rotation amount of the sprocket 9 to the controller 207.
Output to the counter 208. The counter 208 outputs a clutch-on output signal to the clutch brake 210 at every predetermined number of input pulses. The suspension member 203 moves by a predetermined rotation angle, locks the filling casing 4c flowing out from the guide member 108, and stops at a predetermined position.

The intermittent motion of the suspension member 203 described above is continued to form a loop-shaped straight filling casing 4c on the plurality of suspension members 203.

The upper part of the loop of the straight filling casing 4c suspended in a loop by the suspension device 103,
Two rods 106, 106 are passed through the lower portion, and the stuffed casing 4c is removed together with the rod 106 from the suspension device 103 and transferred to the next step.

When the filling is filled over the entire length of the casing 4, the casing 4 attached to the filling nozzle 3
The shrinkage portion 4a of the Therefore, the light emitted from the light projector 12a reaches the light receiver 12b. (Refer to FIGS. 1 and 3 for the light emitter 12a and the light receiver 12b) Then, the filling pump 1 is stopped by receiving the signal from the light receiver 12b via a timer (not shown), and the cylinder 1
8 and the cylinder 19 return to their original positions.

Next, the operation of stopping the filling pump 1 when the casing 4 breaks while filling the filling material will be described. With reference to FIGS. 5 to 7, when casing 4 is smoothly filled with the filler, casing 4 slides on filling nozzle 3. The rotating roller 15 is rotated by the movement of the casing 4, and the rotation of the rotating roller 15 is detected by the sensor 16.
That is, the sensor 16 detects breakage of the casing 4 based on the presence / absence of a pulse signal generated by detecting the peaks 17a and the valleys 17b provided on the rotary roller 15. When the casing 4 is broken, the rotary roller 15 does not rotate, and the pulse signal becomes zero. Sensor 16
If the rotation stop of the rotating roller 15 is detected, the drive motor (not shown) of the filling pump 1 is stopped.

The reason is that the positioning member 5 is inserted from the tip of the filling nozzle 3 during the step of mounting the casing 4 on the filling nozzle 3 and the step of filling the casing 4.
This is because the optimum distances up to the arrangement positions may differ from each other. In this case, the distance during the mounting process is usually larger than that during the filling process. Therefore, as described above, the positioning member 5 moves together with the filling nozzle 3 to the predetermined position of the filling nozzle 3 and further moves to the predetermined position of the positioning member 5 even after the filling nozzle 3 is stopped. The predetermined position of the positioning member 5 during the filling process may differ depending on the type and length of the casing. In order to change this predetermined position, that is, the position of the end portion of the casing 4, the stopper 12 that defines the position of the positioning member 5 is used.
The position of the bracket 12c on which d is erected may be changed. Even if the position of the bracket 12c is adjusted, the projector 12a and the light receiver 12b are attached to the bracket 12c, so that the distance between the end of the casing 4 and the optical axis P is kept constant.

Further, in the present invention, the positioning member is not limited to the above embodiment. For example, when the optimum distance from the tip of the filling nozzle 3 to the position where the positioning member 5 is disposed is the same both in the step of mounting the casing 4 on the filling nozzle 3 and the step of filling the casing 4,
As shown in FIG. 0, the positioning member 5A may be fitted to the filling nozzle 3 and fixed on the filling nozzle 3 by the set screw 5B.

The above description has been given of the embodiment for making the filling diameter uniform, but hereinafter, a proper amount of the filling material is filled in the natural intestine casing in which the outer diameters of the casings in the longitudinal direction are largely different. An automatic filling device for manufacturing a product having a non-uniform filling diameter, and in particular, a control device therefor will be described.
Natural intestine casing such as sheep intestine and pig intestine (hereinafter referred to as casing)
In that case, the outer diameter of the casing changes remarkably, and the strength is not constant. Therefore, if the discharge amount from the filling nozzle is set to the same discharge amount under a constant casing conveying speed, the filling degree is different. . That is, a hard sausage is mixed with a hard portion and a soft portion. Therefore, it may be necessary to control the filling degree so that the casing is filled with the same filling degree while constantly monitoring the filled casing.

An embodiment of the control device for making the filling degree uniform will be described below with reference to FIGS. 22 to 24. A frame body 32 is provided between the elastic ring 31 and the transport device 7, and the frame body 32 has a heavy roller weight 3
3 and a lightweight roller weight 34 are provided adjacent to each other in a vertically slidable manner. The roller weights 33 and 34 are provided at positions to be placed on the casing 36 filled with the filling discharged from the filling nozzle 35, and the casing 36 on the guide portion 32A of the frame 32 is illustrated as shown. The height difference H is generated in the positional relationship between the roller weights 33 and 34 depending on the filling degree. That is, when the filling degree is small (soft), the roller weight 33 on the heavier side is
Of the roller weight 34 on the light side and the relative height difference H between the depression of the roller weight 34 on the lighter side become larger. On the other hand, when the filling degree is large (hard), the relative height difference H between the depression of the roller weight 33 on the heavy side and the depression of the roller weight 34 on the light side becomes small. To detect this height difference H,
Displacement detection members 37 are fixedly provided on both roller weights 33 and 34, and a displacement detection sensor 38 that constantly detects an interval (height difference H) between the displacement detection members 37 is provided.

The signal detected by the displacement detection sensor 38 is given to the motor 42 which drives the filling pump 41 via the control device 39 and the driver 40, and discharges the filling so that the height difference H falls within a certain range. To control the amount,
The number of rotations of the motor 42 is controlled.

Next, another embodiment of the control device for making the filling degree uniform will be described with reference to FIGS. 25 and 26. In this example, when the degree of filling is small (soft), it is noted that the shape of sausage or the like filled in the casing becomes an elliptical shape that spreads left and right by slightly pressurizing the filled casing, When the cross-sectional shape is elliptical, the filling amount is increased, and when the cross-sectional shape is perfectly circular, the filling amount is continued without changing the filling amount.

Referring to FIGS. 25 and 26, a main lever 54 swinging around a pin 53 as an axis is provided on a wall 52 provided with a housing 51 for an elastic ring (not shown). A sub-lever 56 that swings around the pin 55 is provided on the top. The main lever 54 is provided with a displacement detection sensor 57 that detects a height difference K between the main lever 54 and the sub-lever 56.

When the casing 58 filled with the filler moving on the guide member 59 has a perfect circular shape (the state shown in FIG. 26A), the main lever 54
Since the height difference K between the sub-lever 56 and the sub-lever 56 is large, and the filling degree is preferable in this state, the filling amount discharged from the filling pump (not shown) is continued as it is.

Now, when the filling level decreases, the shape of the casing 58 becomes elliptical as shown in FIG. Therefore, the height difference K between the main lever 54 and the sub-lever 56 becomes small, and the discharge amount of the filling pump (not shown) is increased by the signal from the displacement detection sensor 57. As a result, the amount of filling discharged from the filling nozzle into the casing 58 is increased, the filling degree of the casing 58 is increased, and the shape is controlled to be a perfect circle. The control device of this embodiment can also be applied to an artificial casing having an uneven outer diameter.

In the case of discharging the filling from the tip of the filling nozzle to the casing, smearing may occur due to friction with the inner wall of the filling nozzle when the filling passes through the filling nozzle. , If it is discharged into the casing as it is, the product will have a cloudy appearance. Therefore, as shown in (A) and (B) of FIG.
The tip of the filling nozzle 71 has a tapered structure, and a plurality of split grooves 71a cut from the tip surface are provided. In this way, when the split groove 71a is provided at the tip of the filling nozzle 71,
When the filling material is discharged into the casing, agitation occurs in the vicinity of the outer periphery, and the turbidity of the appearance due to smearing is reduced.

The present invention is as described above, but the structure of each part of the present invention is not necessarily limited to the above-illustrated embodiments. Further, the present invention can be implemented by appropriately combining the above-mentioned embodiments, and includes these.

[0096]

According to the method and apparatus for filling sausage or the like of the present invention, the following effects can be obtained. Air mixing is reduced when the casing is filled with filling material. Since the automatic filling is performed by a mechanical device that can detect the end of filling of a natural intestine casing such as sheep intestine or pig intestine, productivity is improved and the cost is low.

With an artificial casing such as a collagen casing, full automatic straight filling can be performed, and productivity is greatly improved. Since the filling is stopped when the casing is broken during the filling of the filling into the casing, the surroundings of the mechanical device are not polluted. The filled outer diameter of the filled casing becomes constant, and the weight of the product becomes constant.

In natural intestine casings such as sheep intestine and pig intestine, there are variations in outer diameter peculiar to individuals, but since the casing is filled while being pulled, such variations in outer diameter peculiar to each other are absorbed, and the filling outer diameter is reduced. It can be made substantially uniform. A natural intestinal straight filled product is obtained with a fill weight that is closer to the sale set weight. In natural intestine casings such as sheep intestine and pig intestine, there is an inherent longitudinal bend in the individual, which appears as a product bend when the filling material is filled, but since the casing is pulled and filled, such a unique bending occurs. The bending can be substantially absorbed and reduced.

An automatic loop system for straight filled products can be obtained if a suspension system is installed. If a loop cutting device is additionally installed, a straight filling product having a shape without bending in the suspension can be manufactured. In a natural intestine casing such as sheep intestine or pig intestine, the filling amount can be automatically increased / decreased according to the variation in the outer diameter peculiar to each individual, and the filling degree can be made uniform. Skilled workers are not required, and costs can be reduced.
