Description

[Detailed description of the invention] [Industrial application field] The present invention is a skewer removal operation for a cylindrical processed food in which the skewer is removed from a processed food in the form of a skewer, such as a bamboo ring. This relates to a device that applies pressure with a roller to remove distortion caused by.

[Prior art]

FIG. 3 is an explanatory diagram schematically depicting a part of the process of processing chikuwa as an example of a cylindrical processed food.

The chikuwa 2a, 2a', which are coated with minced meat on the skewers 1 and baked in an automatic chikuwa grilling machine (not shown), are moved to a certain position, at a certain time interval, and in a certain posture (i.e. in an aligned state). ) being carried out.

When the skewer 1 is pinched between the pinching plates 3 and pulled out in the direction of the arrow A, the bamboo rings 2a and 2a' fall freely as shown by the arrows B and B', respectively.

During the above-mentioned skewer removal operation, the bamboo rings 2a, 2a' are supported by the reaction force in the opposite direction of arrow A by the sandwich plate 3, and the skewer 1 is pulled out in the direction of arrow A, so they are compressed in the drawing direction. cause distortion (specifically,
(length dimension shrinks by 25-30% and wall thickness increases unevenly).

The skewered bamboo wheels are cooled in the subsequent process.
Before being packaged, a pair of rollers 4a, 4b
The material passes through the space and is pressurized in a kneading-like manner to remove distortion.

Chikuwa 2a, 2 passed between rollers 4a, 4b
b' falls freely as shown by arrows C and C' and is loaded onto a conveyor (for example, a bucket conveyor) for the next process.

[Problem to be solved by the invention] As explained with reference to FIG. 3, the bamboo wheels 2a and 2a' immediately before the skewering process maintain an aligned state, but the bamboo wheels 2b and 2b' after the skewering process are Losing alignment.

In the subsequent cooling process, even if the bamboo wheels are misaligned, no particular problems will occur.
When sending the bamboo rings to the automatic packaging machine, which is the final process, the bamboo rings must be lined up as they are transported one after another.

Although devices such as biplaters have been developed to approximately align the bamboo rings, they cannot be expected to achieve the perfect alignment required by automatic packaging machines. Therefore, in the past, the work items were generally arranged and a predetermined number of bamboo rings were manually arranged and fed into an automatic packaging machine.

In order to reduce this wasted labor, skewer removal,
It is best to avoid disturbing the alignment of the bamboo rings during the roller pressing and cooling steps.

For example, as shown in FIG.
It is conceivable that the skewered bamboo wheels 2c, 2c' are received by the conveyor 5 provided with a skewer, and the skewering process is completed in a state where the aligned state is maintained. However, the bamboo rings arranged on the conveyor 5 with positioning means as shown in FIG. 4 cannot be passed through the press roller in this state.

This idea was created in view of the above circumstances.
It is an object of the present invention to provide a press roller device capable of removing distortion while conveying cylindrical processed foods such as bamboo rings in an aligned state.

[Means for solving problems]

According to an experiment conducted by the present inventor in order to achieve the above object, (see Fig. 3) a press roller 4 having a length L larger than the length L of the bamboo ring was used.
It was confirmed that it is not necessary to use a and 4b.
That is, if the center part (other than both ends) of the bamboo ring is pressed with a press roller (not shown) that is shorter than the above-mentioned dimension 1, distortion can be removed to a practically sufficient degree.

In order to apply the above-mentioned principle to practical use, the processed food press roller device according to the present invention has the following features: (a) A cylindrical processed food is leveled and its both ends are supported, a pair of conveyors for conveying the processed food in a direction perpendicular to the longitudinal direction; (f) a positioning means attached to the conveyor; and (c) a cylindrical processed object supported at both ends by the conveyor. a pair of rollers facing each other across the center of the food; (d) two pairs of bearing members supporting the shafts of the pair of rollers; and (e) one pair of bearings for each of the two pairs of bearing members. (f) a driving means for rotating the pair of rollers in the same direction; and (g) the pair of rollers are The circumferential speeds are different, and the differential speed is set to be approximately equal to the conveying speed of the conveying means.

[Effect]

According to the above configuration, the cylindrical processed food is supported at both ends and is strained at the center by a pair of press rollers while being conveyed while maintaining the aligned state.

Moreover, the difference in circumferential speed between a pair of press rollers is 1/2 of the conveyance speed of the conveyor (for example, a chain conveyor).
2, the cylindrical processed food sandwiched between the pair of press rollers rotates on its own axis and rolls at the same speed as the conveyor, without disturbing its aligned state.

Furthermore, since the pair of bearings that support the press rollers are provided with adjusting means for moving them toward and away from each other, even if the distance between the pair of press rollers is adjusted, each The contact states of the press rollers with respect to the processed food are kept equal to each other.

〔Example〕

Figure 2 is a plan view showing one embodiment of the present invention;
The figure is a sectional view thereof.

As shown in FIG. 2, two lines of conveyance lines are provided in this embodiment, but when implementing the present invention, the number of lines of conveyance lines to be provided can be set arbitrarily. The following description will be made using the drawing reference numbers attached to one of the two transport lines. The configuration of the other conveyance line is also similar to this.

A pair of carriers is provided to support both ends of the bamboo ring 2. In this example, a pair of chain conveyors 6, 6 are installed horizontally at the same height to horizontally support the bamboo wheels 2.

(See FIG. 1) Rollers 7 are arranged in a row on the chain conveyor 6 as means for positioning the bamboo wheels 2.

As a result, the large number of bamboo wheels 2 are conveyed in the direction of arrow _V1 at a speed of _V1 while maintaining an aligned state.

The pair of press rollers 8u and 8d are supported by bearing members 9u and 9d, respectively.

The press rollers 8u and 8d have shapes and dimensions corresponding to the central part of the bamboo wheel 2 as shown in FIG. ₂ , and as shown in _FIG . It is driven by

The above-mentioned V ₁ , V ₂ , and V ₃ are set so as to maintain the following relationship: V ₃ −V ₂ ≈2V ₁ (1).

The adjustment shaft 10 to which the handle 10a is attached is provided with a right-hand thread 10b and a left-hand thread 10c, which are screwed into bearing members 9u and 9d, respectively. As a result, when the handle 10a is turned, the bearing member 9
u and 9d move toward and away from each other by the same size. For this reason, a pair of press rollers 9
Even if the distance D between u and 9d is adjusted, both rollers always maintain an equal distance from the transport center line M of the bamboo wheel 2.

If the upper press roller 9u goes down too much, it will press the bamboo wheel 2 against the chain conveyor 6, and if the lower press roller 9d goes up too much, it will flip up the bamboo wheel 2 and make the positioning unstable. In this example, no such problem occurs.

The bamboo ring 2 is conveyed at a speed V ₁ as shown by arrow M (Fig. 1), is sandwiched between a pair of press rollers 8u and 8d, and is rotated by both press rollers. It is sent to the right in the figure at half the circumferential speed difference.

According to the above equation (1), half of the circumferential speed difference (V ₃ −V ₂ ) is equal to the conveyance speed V ₁ , so the bamboo wheel 2 passes between the press rollers 9u and 9d without disturbing the alignment state,
Even after passing, they are conveyed in line on the chain conveyor 6.

As can be easily understood from the above-mentioned effect, it is sufficient that both the left and right sides of equation (1) are approximately equal. The reason is,
The required accuracy for positioning the bamboo wheels 2 on the chain conveyor 6 is "between adjacent positioning rollers 7"
This is because it is sufficient that it does not jump out.

[Effect of idea]

As described in detail above, according to the press roller device of the present invention, it is possible to transport cylindrical processed foods such as bamboo leaves in an aligned state and remove the distortion.
As a result of not disturbing the alignment state, it greatly contributes to the complete unmanned manufacturing and packaging process of processed foods.
