Description

The present invention relates to, for example, a device for skewering (skewering) materials such as chicken and vegetables, and the present invention relates to a skewering device capable of skewering in the same manner as when skewering by human hands.

As a conventional skewering device, the gun skewers supplied from the carry-out part (corresponding to the supply position of the present invention) of the gun skewer alignment and transporting device (corresponding to the skewer supply means of the present invention) are skewered one by one (book). A skewer drum (corresponding to the skewer transporting means of the present invention) that conveys to the extrusion position of the present invention, and a skewering means (corresponding to the skewer extruding means of the present invention) that skewers the gun skewer conveyed by the skewer drum into food. A food-forming skewer device as exemplified in Patent Document 1 is known, which comprises (1), in particular, paragraphs [0013] [0041] to [0047], FIGS. 6, 7 (A) (Patent Document 1). B) See).

The skewering device of Patent Document 1 uses a skewer drum to line up and transport one teppogushi from the carry-out portion to the skewering position, one by one using one pusher (230a) provided in the skewering means at the skewering position. It is extruded to the side of the food to skewer the food.

However, the skewering work efficiency in such a configuration greatly depends on the speed of skewer transfer by the skewer drum and the speed of the piston movement (pushing and retracting operation) of one pusher provided in the skewering means, and therefore the work efficiency. There was a limit to increasing.

In addition, in order to improve the efficiency of skewering work, it is conceivable to equip one skewering device with a plurality of skewering means and skewer drums. However, in that case, due to the fact that one skewering device is equipped with multiple skewering means and skewer drums, the skewer transport path from the carry-out part (supply position) to the skewering position (extruded position) is divided into multiple skewer drums. There is a possibility that a plurality of them will be provided correspondingly and their lengths, that is, the transport distances will be different from each other.

Then, in order to simultaneously push out the skewers at the skewered positions corresponding to each by the skewered means provided, that is, the pushers, the skewers are put on the skewered positions for each skewered position in the plurality of skewered transport paths having different transport distances. Although it is necessary to take some measures such as the need to transport (supply) the skewers while synchronizing the supply timing, Patent Document 1 does not mention this point at all.

It is provided with a regulating member 46.

As shown in FIGS. 13 (a) and 13 (b), the skewer leveling structure 44 includes a skewer pressing member 441 for pressing the lowermost portion 41d in the skewer accommodating space 41s and a skewer S having the vicinity thereof, and a skewer pressing member 441. A coil spring 442 that urges the skewer downward and a support block 443 that supports the skewer pressing member 441 via the coil spring 442 are provided.

Here, the left wall 412 is formed by being divided into front and rear sides in the front-rear direction of the device (see FIGS. 2 to 5), and the central portion of the left wall 412 in the front-rear direction of the device (front and rear of the divided left wall 412). As shown in FIGS. 2 and 13 (a) and 13 (b), the pair of left wall components (between 412A and 412A) constituting the side has a skewer leveling structure arrangement space over the entire vertical direction of the left wall 412. 412s are formed. The skewer accommodating space 41s is opened toward the skewer stab device main body 10 side by the skewer leveling structure arrangement space 412s.

As shown in FIGS. 13 (a) and 13 (b), the skewer leveling structure arrangement space 412s is provided directly above the skewer introduction port 43 of the skewer supply path 42, and in the skewer leveling structure arrangement space 412s, the support block 443 and the support block 443 are provided. The coil spring 442 and the skewer pressing member 441 are arranged in this order from the upper side to the lower side. That is, the skewer pressing member 441 is connected to the support block 443 via a coil spring 442 that expands and contracts in the vertical direction in the skewer leveling structure arrangement space 412s.

Of the skewer leveling structure 44, the support block 443 and the skewer pressing member 441 are arranged so that their right surfaces are substantially flush with the right surfaces of the pair of left and right left wall components 412A and 412A.

However, at the lower part of the skewer pressing member 441, a protruding portion 45 is formed so as to project toward the skewer accommodating space 41s (to the right of the device). The lower surface of the protruding portion 45 forms a part of the lower surface 441d of the skewer pressing member 441. As a result, the lowermost portion of the skewer pressing member 441 is arranged above the skewer introduction port 43 so that the lower surface 441d faces both the lowermost portion 41d of the skewer accommodating space 41s and the skewer supply path 42. It is arranged over 41d and the skewer supply path 42.

The lower surface 441d of the skewer pressing member 441 is formed flat, and the upper surface of the bottom plate 415 gradually descends from the right end (the side of the skewer accommodating space 41s) toward the left side of the device (the side of the supply position Pa). It is formed by tilting at the same tilt angle as.

Further, as shown in FIG. 13A, the skewer leveling structure 44 has a connecting arm 64 extending toward the skewer hopper 40 from the side of the vertically movable plate 58 (see, for example, FIG. 2) described later in the skewer stab device main body 10. The support block 443 of the skewer leveling structure 44 is integrally connected to the right end of the skewer by fastening or the like via a skewer regulating member 46. As a result, the skewer leveling structure 44 and the skewer regulating member 46 descend as the vertically movable plate 58 descends from the steady position as described later.

Specifically, as shown in FIG. 13A, when the vertically movable plate 58 is held in a steady position, the skewer pressing member 441 has a pair of left wall configurations in which the portion directly above the skewer introduction port 43 on the lower surface 441d thereof. It is arranged at the same height as or higher than the lower end 412d of the portions 412A and 412A. When the skewer pressing member 441 is held at this position (non-pressing position), the skewer pressing member 441 releases the pressing of the skewer S held below.

On the other hand, as shown in FIG. 13B, when the vertically movable plate 58 is held in the descending position, the skewer pressing member 441 has a pair of left wall constituent portions 412A, 412A whose lower surface portion 441d is directly above the skewer introduction port 43. It is arranged below the lower end 412d of. In other words, when there is no skewer S below the skewer pressing member 441 at the descending position, the vertical distance between the lower surface 441d of the skewer pressing member 441 and the upper surface of the bottom plate 415 is the diameter of the skewer S. Descent until equal to or smaller than.

As shown in FIG. 13B, when the skewer pressing member 441 at the descending position has a skewer S below, the lower surface 441d of the skewer pressing member 441 has a skewer S below the skewer S. The coil spring 442 is compressed by the reaction force of the contact from above.

As a result, when the skewer pressing member 441 is held in the lowered position, the skewer S to be introduced from the skewer introduction port 43 to the skewer supply path 42 is pressed toward the bottom plate 415 by using the urging force of the coil spring 442. be able to.

Therefore, the raised skewers S are leveled with respect to the upper surface of the bottom plate 415, and the skewers S at the lowermost portion 41d are appropriately introduced into the skewer supply path 42 one by one from the skewer introduction port 43 without being clogged at the skewer introduction port 43. can do.

In particular, as described above, the lower portion of the skewer pressing member 441 is formed with a protruding portion 45 projecting toward the skewer accommodating space 41s. As a result, the skewer S can be pressed and leveled without a gap from the skewer introduction port 43 to the lowermost portion 41d by the skewer pressing member 441, and as a result, clogging of the skewer S at the skewer introduction port 43 can be reliably prevented. ..

Further, the protruding portion 45 formed at the lower part of the skewer pressing member 441 has a skewer S laminated in the vicinity of the skewer introduction port 43 in the skewer accommodating space 41s when the skewer pressing member 441 rises from the descending position to the steady position. It is formed so that it can be scraped up.

That is, the vertically movable plate 58 held on the side of the skewering device main body 10 repeatedly moves up and down (elevates) between the steady position and the descending position as described later. Every time the skewer pressing member 441 rises along with this, the skewer S is laminated in the skewer accommodating space 41s by the protruding portion 45 provided on the skewer pressing member 441 and tends to be pushed toward the skewer introduction port 43. Can be scraped up.

Therefore, the skewer pressing member 441 presses the skewer S at the time of descent by the protruding portion 45 to make it easier to level the skewer S, and as a result, it is possible to enhance the clogging prevention descent of the skewer introduction port 43 by the skewer S.

In the present embodiment, as shown in FIGS. 13 (a) and 13 (b), the upper surface 45a of the projecting portion 45 is directed with respect to the tip end and the base end in the projecting direction in a vertical cross-sectional view along the projecting direction (device left-right direction). The middle part is formed in an isolated shape so as to be recessed downward.

As a result, when the skewer pressing member 441 rises, the skewer S held directly above the protruding portion 45 can be fastened (that is, laminated) to the concave upper surface of the protruding portion 45, so that the skewer S can be scratched by the protruding portion 45. The raising effect can be enhanced.

Further, as shown in FIGS. 13 (a) and 13 (b), the skewer regulating member 46 is located on the side of the skewer piercing device main body 10 with respect to the skewer leveling structure 44 provided in the skewer leveling structure arrangement space 412s, in other words, the supply position Pa. It is placed adjacent to the side of.

The skewer regulating member 46 is formed in a plate shape extending in the vertical direction and the device front-rear direction (see FIG. 7), and as shown in FIGS. 13 (a) and 13 (b), the upper portion of the skewer regulating member 46 is connected. It is integrally connected to the right end of the arm 64 by a bolt or the like. As a result, the skewer regulating member 46 moves up and down integrally as the vertically movable plate 58 on the skewering device main body 10 side moves up and down.

The lower portion of the skewer regulating member 46 is formed in a protruding shape toward the lower side, and the lower portion of the protruding shape is formed so as to be inclined so that the right side gradually approaches the left side toward the lower side.

When the skewer regulating member 46 is held in a steady position, the vertical distance between the lower end 46d of the skewer regulating member 46 and the upper surface of the bottom plate 415 immediately below the lower end 46d is larger than the diameter of the skewer S. Be distributed. That is, as shown in FIG. 13A, when the skewer regulating member 46 is held in a steady position like the skewer pressing member 441 provided in the skewer leveling structure 44, the skewer S held in the skewer supply path 42 is supplied. It does not restrict movement to the side of position Pa.

As shown in FIG. 13B, when the skewer regulating member 46 is held in the descending position, the vertical distance between the lower end 46d of the skewer regulating member 46 and the upper surface of the bottom plate 415 immediately below the lower end 46d is a skewer. It is arranged so as to be equal to or smaller than the diameter of S. That is, when the skewer regulating member 46 is held at the descending position, the skewer is lowered so as to divide the skewer supply path 42 in the middle, and the skewer held on the skewer introduction port 43 side of the lowered skewer regulating member 46 in the skewer supply path 42. It is restricted that S moves to the supply position Pa side.

According to the above configuration, when the skewer S is pressed by the skewer pressing member 441, the skewer regulating member 46 tries to forcibly push the skewer S in the skewer supply path 42 toward the supply position Pa, for example. Even in this case, the skewer S is restricted from moving toward the supply position Pa along the skewer supply path 42. As a result, it is possible to prevent the plurality of skewers S from being collectively pushed out to the side of the supply position Pa, that is, to the side of the skewer transfer conveyor 11 through the skewer supply path 42.

[Tray and material holding member]
The configurations of the tray 100 and the material holding member 110 will be described with reference to FIGS. 16 (a) and 16 (b), FIGS. 17 (a) and 17 (b), and FIGS. 18 (a) and 18 (b). 16 (a) (b) to 18 (a) (b) are shown with reference to the posture in which the tray 100 is placed on the tray transport lane 21.

The tray 100 is formed in a rectangular shape in a plan view, and on the upper surface thereof, concave material placing portions 101 on which a plurality of materials F are placed side by side on the same line are arranged in three rows along the left-right direction of the device. It is installed (see FIG. 18 (b)).

As shown in FIG. 17B, the bottom surface 102 of the material mounting portion 101 is V in a cross-sectional view orthogonal to the longitudinal direction of the material mounting portion 101 (the direction in which the materials F are placed side by side on the same line). It is formed in a character shape. In other words, the bottom surface 102 of the material mounting portion 101 has the deepest portion 102b located at the center in the orthogonal cross-sectional view and the inclined portion 102a inclined so as to be gradually higher on both outer sides of the deepest portion 102b. It is formed by.

As shown in FIGS. 16 (a), 16 (b), 17 (a), and 18 (b), skewer guide grooves 103 are concave from the upper surface on both outer sides of the material mounting portion 101 of the tray 100 in the longitudinal direction. Is formed in. The skewer guide groove 103 guides the skewer S skewered with respect to the center of the material F placed on the material placing portion 101 in the skewering direction.

The material placing portion 101 is provided with at least one partition plate 104 (two in this example) for partitioning a plurality of materials F placed along the longitudinal direction of the material placing portion 101 from each other. Thereby, in this example, the material placing portion 101 is divided into three spaces for placing the material F by the partition plate 104.

The partition plate 104 is provided so as to be slidable along the longitudinal direction of the material mounting portion 101 (see FIGS. 17 (b) and 18 (b)).

Specifically, the partition plate 104 includes a partition plate main body 105 and engagement projections 106 protruding outward in the width direction from both sides of the partition plate main body 105 in the width direction. On the other hand, on the inner wall surfaces on both sides of the material mounting portion 101 in the tray 100 in the width direction, an engaging groove 107 that engages the engaging projection 106 of the partition plate 104 extends over the entire length of the material mounting portion 101 in the longitudinal direction. It is formed over.

As a result, the partition plate 104 is slid along the longitudinal direction of the material mounting portion 101 in a state of being engaged with the engaging groove 107, whereby the space partitioned by the partition plate 104 of the material mounting portion 101 is created. It can be adjusted to a size suitable for the size of the material F placed in the space.
That is, even when a plurality of materials F placed on the material placing portion 101 have different sizes, the skewers can be appropriately skewered without a gap between the plurality of materials F to be skewered.
A skewer guide groove 105a extending downward from the upper end is formed in the central portion of the partition plate main body 105 in the width direction corresponding to the skewer guide groove 103.

Further, as shown in FIGS. 16 (a) (b), 17 (a), and 18 (a) (b), the material holding member 110 corresponds to the tray 100 and has substantially the same size as the tray 100 in a plan view. Includes a base 119, a plurality of material holding portions 13 arranged below the base 119, and a coil spring 118 interposed between the base 119 and each of the plurality of material holding portions 13. ing.

As shown in FIGS. 17 (b) and 18 (a), the material holding portion 13 corresponds to the three rows of material mounting portions 101 arranged on the upper surface of the tray 100, and in each material mounting portion 101. A plurality of materials F are arranged on the lower surface of the base portion 119 so as to correspond to each of the placement spaces of the material F partitioned by the partition plate 104. The lower surface 13a of the material holding portion 13 is formed in an inverted V shape in an orthogonal cross-sectional view in the longitudinal direction of the material placing portion 101 in the bottom view.

Further, as described above, the lower surface 13a (pressing surface of the material F) of the material holding portion 13 is formed in an inverted V shape in an orthogonal cross-sectional view in the longitudinal direction of the material mounting portion 101, and as described above, the material is mounted. The bottom surface 102 of the placement portion 101 is formed in a V shape in an orthogonal cross-sectional view in the longitudinal direction of the material placement portion 101.

As a result, when the material F placed on the tray 100 is pressed by the material holding portion 13, the V-shaped bottom surface 102 of the material placing portion 101 and the inverted V-shaped lower surface 13a of the material holding portion 13 are formed. The material F can be sandwiched so as to be closer to the central portion in the width direction (left-right direction of the device) and the vertical direction. Then, in this state, by skewering the center of the material F at the skewering position Pd, the material F can be firmly skewered.

Further, the coil spring 118 urges the material pressing portion 13 toward the material F by compressing the material F in the axial direction (vertical direction) when the material F is pressed by the material pressing portion 13. As a result, the material pressing portion 13 alleviates the influence of the difference in size and hardness of the plurality of materials F placed on the tray 100, and presses each of the plurality of materials F with an appropriate pressing force by the material pressing portion 13. be able to.

The tray 100 and the material holding member 110 described above have been described by taking as an example the material F formed for chicken meat among various parts of chicken, but the material F is not limited to this, and for example, FIGS. 19 (a) and 19 (b) are shown. As shown in the above, those formed for chicken skin or for slip (gizzard) as shown in FIGS. 20 (a) and 20 (b) may be adopted, or a plurality of them may be provided depending on the material F to be skewered.

For example, when the tray 100 and the material holding member 110 are formed for chicken skin, the tray 100A corresponds to the thin chicken skin and the tray 100A is placed on the bottom surface 102 of the material placing portion 101 as shown in FIG. 19 (b). As shown in FIG. 19A, the member 110A is preferably formed on the lower surface 13a of the material holding portion 13 with a plurality of irregularities.

Further, the bottom surface 102 of the material mounting portion 101 is formed in a V-shaped cross section (specifically, a V-shape in a cross-sectional view orthogonal to the longitudinal direction of the material mounting portion 101) as described above (FIG. 17). (Refer to (b)), when the above-mentioned tray 100 is used as the material F formed for, for example, the meat of the buttocks (also referred to as “bonjiri” or “sankaku”) among various parts of chicken. As shown by a virtual line in FIG. 17B, it is preferable that the bottom surface 102c of the material placing portion 101 in the tray 100 is formed in a V-shape with a recess having a recess 102cd.

The V-shaped bottom surface 102c with a recess is provided with a recess 102cd that is stepped lower than both outer portions in the central portion of the material placing portion 101 in the orthogonal cross-sectional view, and is provided on both outer portions of the recess 102cd. An inclined portion 102ca that is inclined so as to gradually increase toward the outside is provided.

The recess 102cd is formed so that the bottom surface 102cc of the recess 102cd is in a horizontal plane. Further, in this example, the recess 102cd is formed over the entire length of the material mounting portion 101 in the longitudinal direction, but may be formed in a part or a plurality of portions of the material mounting portion 101 in the longitudinal direction. ..

According to the above configuration, when the meat of the buttocks of the chicken as the material F placed on the bottom surface 102c of the material placing portion 101 of the tray 100 is pressed by the inverted V-shaped lower surface 13a of the material pressing portion 13, the said The buttock flesh is guided to enter the central recess 102cd along the inclined surfaces 102ca on both outer sides in the above-mentioned orthogonal cross-sectional view of the bottom surface 102c, and the flesh of the hard part around the coccyx in the buttock enters the recess 102cd. Therefore, the meat of the buttocks can be stably placed in a state where the width of the buttocks is firmly aligned with the central portion of the bottom surface 102c.

The bottom surface 102c formed in such a V-shaped recess is applicable to the case where the material F such as the above-mentioned buttock meat having a relatively hard part (coccyx peripheral part) is placed among the chicken parts. It is preferable to do so. However, the bottom surface 102c formed in a V-shape with a recess is not limited to being applied to the meat of the buttocks, but is also used for the above-mentioned thigh meat, chicken skin or scraping, or is applied to other parts other than the above. May be good.

Further, in the skewering device 1 of the present embodiment, as described above, the bottom surface 102 of the material mounting portion 101 is not limited to being formed in a V-shape with a recess, and the lower surface 13a of the material holding portion 13 is an inverted V-shape with a recess. It may be formed into a shape.
Needless to say, the material F handled in the skewering apparatus 1 of the present embodiment may be applied to meat including processed meat (sausage or the like) and foodstuffs other than meat in addition to chicken.
