Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a skin scraping apparatus which can be used for scraping burnt skin of bread in the production of bread crumbs.

[0002]

2. Description of the Related Art During the production of bread crumbs, if burnt skin remains on the surface of bread, the appearance of the produced bread crumbs becomes slightly brownish, and the value as a commercial product decreases.
Class 2 products. Therefore, in order to produce completely white bread crumbs, it is common to provide a process for scraping the burnt skin of bread as a pre-process for producing bread crumbs by grinding. Conventionally, Fig. 1 (a) for scraping the bread skin
Or, as shown in (b), a hemispherical or elliptical spherical metal shaving tool having a large number of projections on the surface has been used.
As shown in FIG. 2, the scraper is attached to the rotary drive, and the operator holding the pan presses the pan against the rotary-driven scraper and moves the pan so as to follow the outer shape of the pan. The epidermis is scraped. Although the bread has a shape with irregularities, the operator must work while appropriately adjusting the position of the shaving tool to which the bread strikes, since the skin is scraped regardless of the uneven shape. For example, in the case of shaving a relatively flat side surface or bottom surface, the shaving may be performed by placing the bread in front of the shaving tool, but in the case of shaving the concave portion formed on the upper surface of the bread, the edge of the shaving tool is used. Alternatively, a scraping operation is performed using the tip portion.

[0003]

The conventional method is a hand-held operation by an operator, and since the bread has an uneven surface shape, in order to scrape the skin evenly, the operator must adjust the bread to the uneven shape. In addition, it was necessary to work while moving the bread by hand so as to hit the shaving tool at the optimum position, and thus the productivity could not be so high.

[0004] Further, the operator works to scrape the skin over the entire surface of the bread with as little shaving as possible. However, the shaving amount is manual and the shaving amount is fixed due to the complicated uneven shape of the bread surface. It is difficult to perform the cutting, and the scraping amount is increased more than necessary, so that the yield is deteriorated.

Further, since the work is performed while appropriately moving the pan held in the hand with respect to the rotating scraping tool, there is a possibility that the operator's hand may hit the rotating scraping tool. Further, if the force for holding the bread during the shaving operation is weak, the bread may be skipped.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-described problems, and enables a high yield of a skin or the like of a bread or the like to be removed without requiring manual work and regardless of the uneven surface shape. It is an object of the present invention to provide a device capable of performing the above.

[0007]

In the apparatus for scraping skin according to the present invention, a plurality of thin plate-shaped shaving blades are stacked on a support shaft attached to a rotating body and individually rotatably fitted. A rotating blade assembly, the sharpening blade having teeth extending radially outwardly along a leading edge thereof, wherein during rotation of the rotating blade assembly, the sharpening blade engages the teeth with the surface of the article. By the combination, the article is individually rotated in a direction opposite to the rotation direction at an angle corresponding to the unevenness of the article against the centrifugal force.

[0008] By the rotation of the rotary blade assembly, the tooth portion formed at the front edge of the cutting blade in the rotation direction hits a work (article such as a bread for shaving the skin), and the skin is shaved. When shaving the skin of the work, if the work is located far from the shaving blade, the work hits the tip side of the tooth part (relative rotation angle of the shaving blade with respect to the support shaft increases), and the work When it is located near, the work hits the root side of the tooth portion (the relative rotation angle of the cutting blade with respect to the support shaft becomes smaller). Regardless of the relative rotation angle of the cutting blade with respect to the support shaft, the degree of engagement of the teeth is equalized. Therefore, even if the work has irregularities, substantially uniform shaving of the skin is realized.

It is preferable that the leading edge of the shaving blade having a tooth portion has an arc shape that retreats in a direction opposite to the direction of rotation from the center of rotation to the outside. With this configuration, regardless of the rotation angle of the shaving blade (irrespective of the unevenness of the article), the engagement state (depth of engagement) of the tooth portion with the article is more constant, and a more uniform skin scraping operation is realized. Can do it.

The rotary blade assembly can be constructed by providing a plurality of support shafts, each of which has a plurality of cutting blades overlapped and loosely fitted between a pair of disk-shaped rotary members at circumferential intervals. With this configuration, the efficiency of the scraping operation can be increased.

In the case where the article to be cut off the skin as a workpiece has a substantially rectangular parallelepiped shape like a bread, three pairs of rotary blade assemblies spaced parallel to each other with the opposing surface of the rectangular parallelepiped are provided. The three sets of rotary blade assemblies are sequentially provided in the direction of transporting the articles so that the skin on the facing surface of the article having a substantially rectangular parallelepiped shape can be sequentially scraped off. According to this configuration, it is possible to cut the entire surface of the skin by passing the substantially rectangular parallelepiped work only once, thereby improving the working efficiency.

The direction in which the article is transferred to the rotary blade assembly is such that the cutting blade engages the article from the rear side in the feed direction with respect to the article being transferred. With this configuration, there is an effect that the shaving blade can be stably engaged with the article without generation of galling.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a bread scraping apparatus according to an embodiment of the present invention; 3 and 4, three work support rods 10 are provided horizontally and in parallel, followed by three work support rods 10 ', and at the same height with respect to the end of the work support rod 10'. And three horizontal and parallel work support rods 10 "are provided at the same position.
Work holding rods 12, 12 ', 12 "are provided in parallel vertically upward with respect to each of 0, 10', 10". Work support rod 10, 1
A transport path W for the pan P, which is a work, is formed between 0 ', 10 "and the work holding rods 12, 12', 12".

There are three pairs of rotary blade assemblies spaced along the transport path W along the transport path W, such as 14, 16, and 18. The first pair of rotary blade assemblies 14 are vertically spaced apart, but the pair of downstream rotary blade assemblies 16,
18 are installed horizontally apart. The three pairs of rotary blade assemblies 14, 16, and 18 can successively cut the skin on the three opposing surfaces of the pan, which is a substantially rectangular parallelepiped work, during the transfer of the pan along the transport path W.

The movement of the pan P along the conveyance path W is performed by a pair of belt conveyors 20, 22, 22, which are arranged so as to sandwich the conveyance path W.
Performed by 24,26. The belt surface of each belt conveyor extends in the vertical direction, and the pan P is transferred by sandwiching the opposite vertical side surface between the belts. That is, the pan from which the skin is to be scraped is introduced into the transport path W between the work supporting rod 10 and the work holding rod 12 from the entrance as shown by an arrow a, and the first rotary blade assembly is transported by the belt conveyor 20. A pair of solids 14 is used to scrape the skin of the pan on the vertically spaced opposing surfaces, and then by a second pair of horizontally spaced rotating blade assemblies 16 on the second opposed surface of the pan. Is cut off. In the meantime, the transfer of the bread is taken over by the belt conveyor 22 and transferred as indicated by the arrow b. After the second counter-surface of the bread has been scraped, the bread is transferred to belt conveyor 2
4 and is advanced to the position of the end of the first linear portion of the transport path W as indicated by P '. A transfer cylinder 28 is arranged outside of this position, and the pan P 'is extended by extending its piston rod 28-1 which is normally in the retracted position, so that the pan P'
To the downstream side of the The third pair of conveyor belts 26 is fed toward the outlet as indicated by arrow c, and during the transfer, the third pair of rotary blade assemblies 18 scrape the skin on the remaining opposing surface of the pan. It is. The bread P whose surface has been completely shaved in this way is discharged from the exit by the delivery roller 30 as shown by the arrow d, and the next step (pulverization step, etc.)
Sent to

As shown in FIG. 4, a shavings collecting chute 32 and a collecting box 33 are provided below the first pair of rotary blade assemblies 14 and the second pair of rotary blade assemblies 16, and a third pair of rotary blade assemblies. A shavings collecting chute 34 is provided below the rotary blade assembly 18.
And a collection box 36. Rotary blade assembly 14,
The shavings generated during the skin scraping operation by the 16, 16 are collected in the boxes 33, 36 via the chutes 32, 34.

Next, the structure of the rotary blade assemblies 14, 16 and 18 will be described.
Because the shaving of the skin on the two opposing surfaces is performed in one pass,
They are sequentially arranged on the transport path W, and have basically the same structure except for the size of the length dimension. This will be described with reference to FIGS. 5 and 6. A lid plate 40 is integrally fixed to both ends of a cylinder 38 concentric with the rotation center of the assembly by welding or the like. Disks 42 as rotating bodies of the present invention are located at both ends of the cylinder 38, and the disks 42 are fixed to the cover plate 40 by bolts 44 arranged at equal intervals in the circumferential direction.
A stub shaft 46 is located outside each disk 42. The stub shaft 46 has an enlarged diameter portion 46-1 at one end thereof, and bolts 48 are inserted through holes formed at equal intervals in the circumferential direction in the enlarged diameter portion 46-1 and fastened to the disk 42. You. Rotational motion from a rotary drive motor is transmitted to one of the stub shafts 46 as described below, so that the rotary blade assembly 14 rotates about a center line 50.

A plurality (six in this embodiment) of support shafts 52 extending in parallel with the center line 50 are arranged between the disks 42 at both ends of the assembly at equal intervals in the circumferential direction. FIG.
And FIG. As shown in FIG. 5, the support shaft 52 has a portion whose both ends are slightly smaller in diameter. By inserting this portion into a hole formed in the disk 42,
Are fixed to the disk 42. An appropriate number of support plates 54 are fixed to the cylinder 38 constituting the central axis of the assembly at an interval in the axial direction, and the support plates 54 are integrated with the cylinder 38 by welding. Then, the support shaft 52 is inserted into the support plate 54 at the intermediate portion in the axial direction,
The support shaft 52 is supported without bending regardless of the shaft length.

The shaving blade 56 is formed of a thin plate material, and a large number of the shaving blades 56 are inserted into the support shaft 52 with the spacer 58 interposed therebetween. The diameter of the hole 60 (see FIG. 7) formed in the shaving blade 56 for inserting the support shaft 52 is such that the shaving blade 56 can freely rotate with respect to the support shaft 52 but does not substantially rattle. It has a dimensional relationship. And
Fully-cutting blade 5 including spacers 58 in a stacked state
The axial length of 6 is such that there is substantially no gap between the disks 42, in other words, there is substantially no backlash in the axial direction, but free rotation of the individual cutting blades 56 about the support shaft 52 is allowed. Has been. Since the shaving blades 56 can rotate freely with respect to the support shaft 52, the individual shaving blades 56 exert a centrifugal force and a cutting resistance of the pan skin during the shaving operation of the bread skin as described later. Are rotated with respect to the support shaft 52 until the balance is achieved. Therefore, a constant shaving force (= centrifugal force) regardless of the unevenness of the bread
Can cut off the skin. In addition, the sharpening blade 5
6 has substantially no backlash in the inserted state with respect to the support shaft 52, so that there is almost no vibration and no accompanying noise during operation. Since the vibration is small, the life of the component can be extended.

FIG. 7 shows a single-piece shape of the shaving blade 56, which has a substantially half-moon shape, and has a hole 60 formed at one end. As described with reference to FIG. The fitting state is such that the cutting blade 56 can rotate freely with respect to the shaft 52 but has substantially no play. Saw blade-shaped teeth 62 are provided on the arc-shaped edge of the substantially half-moon-shaped shaving blade 56 from a portion near the hole 60 to an end opposite to the hole 60. The tooth portion 62 is formed along a semicircular arc N, and the direction in which the arc N extends is in a direction opposite to the rotation direction F of the rotary blade assembly as it is located further outward from the rotation center O of the cutting blade 56. It is the direction to retreat. Therefore, so that the distance to the teeth 62 located on the circular arc shape from the rotation center O increases gradually from a minimum value r ₁ in the direction opposite to the rotational direction F to a maximum value r _2. Due to such a shape of the shaving blade 56, even when the shaving required surface has irregularities during the shaving operation, the shaving blade 56 rotates individually at an angle corresponding to the unevenness, and is constant regardless of the surface unevenness. An amount of shaving can be performed.

In FIG. 5, the position of the support plate 54 is not at the same axis position between the support shafts 52 which are circumferentially separated from each other, and there is an offset δ. By providing the offset δ, the axial position of the cutting blade 56 can be shifted little by little between the support shafts 52 that are spaced apart in the circumferential direction. As a result, the rotary blade assembly 1
During rotation of 4, 16, and 18, the contact of the shaving blade 56 with the surface of the pan can be caused uniformly (without interruption) along the axial direction, so that no shaving remains. Instead of offsetting the position of the support plate 54, it is also possible to change the thickness of the cutting blade 56 or the thickness of the spacer.

FIG. 6 shows the state of each cutting blade 56 when the rotary blade assembly is rotated (the direction of rotation is arrow F) in a state where the skin is not cut. Since the shaving blade 56 is free with respect to the support shaft 52, the shaving blade 56 is expanded so as to be uniformly directed in the diametric direction under the centrifugal force. In the state of the assembly, the edge of the shaving blade 56 having the saw-tooth-shaped teeth 62 is rotated in the rotation direction F of the assembly.
As described later, the front edge formed with the sawtooth-shaped teeth 62 of the shaving blade 56 acts on the pan to be transferred from the back side thereof, as described later. Then, the skin of the bread is shaved.

Needless to say, it needs to be designed.

As described above, in the embodiment of the present invention, the shaving blade 56 of the rotary blade assembly is engaged with the transferred pan P from the back side. That is, as shown in FIG.
The transferred pan P (transfer direction M) is directed to the cutting blade 5
Reference numeral 6 denotes the side of the rotary blade assembly 18 which is moved toward the pan (downward in the rotation direction F) (the left side in FIG. 8). Therefore, as shown in FIG. 9, the movement of the tooth portion 62 and the movement of the pan P are in the same direction (rightward in FIG. 9) at a position where the cutting blade 56 contacts the surface of the pan P. In this case, the epidermis of the bread P is subjected to a scraping action according to the movement speed of the tooth part 62-the movement speed of the pan. Therefore, the rotation speed of the rotary blade assembly 18 and the transfer speed of the pan P (the transfer conveyor
20, 22, and 26 rotation speeds).

When the direction of transport of the bread P is set to the opposite direction (the direction opposite to the arrow M in FIG. 8), the blade portion 62 hits the transported bread from the near side. It is preferable that the cutting blade 56 hit the pan from the back side in the feed direction as in the embodiment of the present invention.

Next, a rotary drive mechanism for rotating the rotary blade assemblies 14, 16, 18 will be described. In this embodiment, the rotary drive mechanism is provided independently for each assembly. Since the structure is basically the same, the drive mechanism of the rotary blade assembly 14 will be mainly described. In FIG. 3, both ends of the rotary drive shaft 64 are supported by ball bearings 66, and the rotary shaft (not shown) of the electric motor 67 is connected to the rotary drive shaft 64 by appropriate means. The rotational motion of the rotation shaft is transmitted to the rotation drive shaft 64. One end of the pair of arms 68 is rotatable about a rotation drive shaft 64 at one end, and stub shafts 46 at both ends of the rotary blade assembly 14 are rotatably supported at the other end of the arm 68. A reinforcing rod 70 is stretched between the pair of arms 68 to give the arm 68 rigidity. As a result, the arm 68 can rotate around the center line of the rotation drive shaft 64 without bending despite the assembly 14 being attached between the front ends.

A pulley 72 is fixed on the rotary drive shaft 64, while a pulley 74 is also fixed on the stub shaft 46 at one end of the rotary blade assembly 14, and a belt 76 is routed between these pulleys 72, 74. . Therefore, the rotation of the rotating shaft of the electric motor 67 is controlled by the pulley 72, the belt 76 and the pulley 7.
The outer skin of the bread that is transmitted to the rotary blade assembly 14 through the transport chute 4 and sent to the transport chute is cut off.

The center of rotation of the second rotary blade assembly 16 is vertical. Therefore, the arm 78 supporting the assembly 16 is provided at one end thereof so as to be rotatable in a horizontal direction around a vertical center line concentric with the rotation drive shaft of the motor 80. The rotary blade assembly 16 is provided at the other end of the arm 78. In this embodiment, the second rotary blade assembly 16
Is for shaving the thinner side of the pan P, the axial length of the second assembly 16 is
Can be shorter than that of Therefore, the arm 78 is provided only on one side of the assembly 16 and the
Reference numeral 6 denotes cantilever support (see FIG. 4). If necessary, the arms 78 may be provided on both sides of the second rotary blade assembly as well as the first rotary blade assembly 14 so as to be supported at both ends. Further, a pulley-belt drive mechanism similar to that of the first rotary blade assembly 14 is provided to transmit the rotary motion of the rotary drive shaft of the electric motor 80 to the rotary blade assembly 16.

The third rotary blade assembly 18 has a vertical center of rotation similarly to the second rotary blade assembly 16, and the drive motor 82 has a vertical rotary drive shaft. Since the side of the pan supported by the third rotary blade assembly 18 is also thin, the axial length of the assembly 18 is short, and the third rotary blade assembly 18 is cantilevered by one arm 84. I have.
Similarly to the first and second assemblies 14 and 16, the rotation of the drive motor 82 is transmitted to the rotary blade assembly 18 by a pulley-belt drive mechanism.

The rotary blade assembly 14, 1 during the skin scraping operation
It is necessary for Nos. 6 and 18 that the surface of the bread be pressurized with an appropriate force in order to realize a stable shaving operation.
With respect to the rotary blade assembly 14 having a horizontal rotation axis, a balance weight having an appropriate weight is provided on the free end side of the arm 68, and an appropriate pressing force is applied to the work by balancing the weight with the weight of the rotary blade assembly 14. be able to. Also,
Just by balancing the weight and the own weight, the assembly 14 moves up and down due to the unevenness of the surface of the bread to scrape the skin,
If the movement is too light, the assembly 14
May rise, and the surface may not be scraped.
Therefore, a well-known damper mechanism may be provided to apply a brake to the vertical movement of the assembly 14 due to the unevenness of the bread surface.

Since the rotating shafts of the second and third rotary blade assemblies 16 and 18 are vertical, it is preferable to provide a hydraulic or spring type pressing mechanism. By pressing the rotary blade assemblies 16 and 18 against the work under an optimum pressure by hydraulic pressure or spring, stable cutting operation can be secured.

Although the embodiment of the present invention has been described as being applied to the scraping of burnt skin of bread for bread crumb production, other than this, peeling of vegetables such as potatoes and burdock, descaling of fish, The apparatus of the present invention can be applied to paint removal, deburring, and the like.
