Description

  The present invention relates to a skewer alignment apparatus and a dumpling making machine.

2. Description of the Related Art Conventionally, in a dumpling manufacturing machine that manufactures skewer dumplings, for example, as in Patent Document 1, a skewer is automatically applied to dumpling fabrics (ball dumplings) formed into ball units or just before dumping into a ball unit. There is a device provided with a stab device (skewer device) and a device (skewer supply device) for supplying one skewer to the skewer device one by one.
The skewer supply device includes a skewer alignment device that aligns the inserted skewers in a row so that the skewers can be supplied to the skewering device one by one only by inserting a large number of skewers.

This skewer aligning device has a skewer alignment conveying surface (an angled surface of a chevron) extending from the lower side of the insertion port for inserting the skewer toward the skewering device side. In addition, at the upstream end of the alignment transport surface located below the input port, the skewer orientation is adjusted so that the longitudinal direction of the inserted skewer is orthogonal to the longitudinal direction of the alignment transport surface. On the other hand, a skewer alignment roller (agitating roller) is provided that imparts a conveying force for conveying from the upstream side to the downstream side of the alignment conveyance surface.
That is, the skewer thrown into the upstream end portion of the aligning and conveying surface is maintained in a line in the longitudinal direction of the aligning and conveying surface by the skewer aligning roller, and from the upstream side to the downstream side of the aligning and conveying surface. Will be transported.

In addition, in recent years, as a skewer for skewers, in addition to a round skewer formed in a simple round bar shape, for example, as shown in FIG. In many cases, a gun skewer 100 having a flat grip portion 100b that is wider than 100a is used. The other end portion of the skewer bar portion 100a in the longitudinal direction is a sharp skewer tip portion 100c.
For this reason, in the skewer alignment apparatus described in Patent Document 1, alignment is performed on one end portion in the width direction of the alignment transport surface so that only the skewer bar portion 100a of the gun skewer 100 is disposed on the flat alignment transport surface. An insertion groove is formed which is recessed from the conveying surface and accommodates the grip portion 100b of the gun skewer 100. Thus, by not arranging the gripping portion 100b of the gun skewer 100 on the alignment conveyance surface, the gun skewer 100 is arranged in the longitudinal direction of the alignment conveyance surface so that the longitudinal direction of the gun skewer 100 is orthogonal to the longitudinal direction of the alignment conveyance surface It is possible to arrange them in a row.

Japanese Patent No. 4184112

By the way, in the conventional skewer aligning apparatus, the posture of the skewer thrown in and deposited on the upstream end of the aligning and transporting surface is set so that these skewers are splashed above the aligning and transporting surface by the skewer aligning roller, or up and down. It is arranged by being stirred so as to shake.
However, when a large number of skewers are thrown into the upstream end portion of the aligning and conveying surface in the conventional skewer aligning device, the skewer is deposited above the skewer disposed immediately above the upstream end portion of the aligning and conveying surface. Since the weight of many skewers is applied, the skewers arranged immediately above the alignment conveyance surface cannot be stirred as described above. In addition, a large number of skewers deposited above are less likely to vibrate up and down due to their weight. As a result, there arises a problem that the posture of the skewer cannot be adjusted, and the skewer cannot be transported from the upstream side to the downstream side of the alignment transport surface by the skewer alignment roller. In addition, there is a possibility that the weight of a large number of accumulated skewers may hinder the operation of the skewer alignment rollers.
From the above, when using the above conventional skewer alignment device, it is necessary to keep the amount of skewers charged at a time small so that skewer alignment transport does not stop, so the number of skewer insertions increases. In addition, handling of the skewer alignment device and the dumpling manufacturing machine including the same is troublesome.

  The present invention has been made in view of the above-described circumstances, and enables a skewer alignment apparatus that can be easily conveyed even when a large number of skewers are simultaneously inserted, and a skewer manufacturing apparatus including the skewer alignment apparatus. The purpose is to provide.

In order to solve this problem, the skewer aligning device of the present invention is formed in a box shape that opens upward so that the skewer can be thrown from above, and the skewer throwing portion arranged so that the bottom surface is inclined with respect to the horizontal plane. And an alignment conveying surface that is connected to the lower end in the inclination direction of the bottom surface of the skewer insertion portion and extends in the alignment direction of the skewer so that the skewer is aligned in a direction perpendicular to the longitudinal direction thereof, and the skewer A box-shaped alignment table having a pair of side plates erected at the end in the width direction of the alignment conveyance surface orthogonal to the alignment direction of the alignment, and a base in the extending direction of the alignment conveyance surface located on the skewer loading portion side The skewers provided at the ends are arranged one by one so that the longitudinal direction of the skewers is orthogonal to the extending direction of the aligning and transporting surfaces, and arranged on the aligning and transporting surfaces. Alignment conveyance that urges the skewers one by one toward the tip end side in the extending direction of the alignment conveyance surface Above the aligning and conveying surface, so that a gap having the same dimension as the thickness of the skewer is formed between the means and the aligning and conveying surface on the front end side of the aligning and conveying surface with respect to the skewer aligning and conveying unit. Sweeping back the other skewer deposited on the skewer arranged and transported toward the tip end side of the alignment transport surface by the biasing force of the skewer alignment transport means to the base end portion of the alignment transport surface Means, and a partition plate arranged between the skewer input portion and the alignment table and supporting the skewer deposited on the bottom surface of the skewer input portion, the partition plate from the skewer input portion side It is possible to move between a restricting position for restricting the movement of the skewer to the alignment table and an allowable position for allowing the skewer to move.
When the partition plate is arranged at the permissible position, there is a gap between the partition plate and the bottom surface of the skewer insertion portion so that the skewer accommodated in the skewer insertion portion can move to the alignment table side by its own weight. It shows the state of being formed.

  In the skewer alignment apparatus according to the present invention, it is possible to intermittently supply the skewer thrown into the skewer insertion portion toward the alignment table by repeatedly moving the partition plate between the restriction position and the allowable position. is there. In addition, the amount of skewer supplied to the alignment table is determined by the size of the gap between the partition plate arranged at the allowable position and the bottom surface of the skewer insertion portion, and the partition plate between the regulation position and the allowable position. It is possible to adjust by appropriately controlling the moving speed of.

  By realizing intermittent supply of skewers to the alignment table in this way, even if a large number of skewers are inserted into the skewer insertion portion at once, the base end portion of the alignment conveyance surface (especially on the alignment conveyance means) The amount of skewers deposited on the can be reduced. Therefore, it is possible to prevent the function of the aligning and conveying means that adjusts the posture of the skewer and urges the skewer toward the front end side of the aligning and conveying surface from being hindered by the weight of the skewer. That is, even if a large number of skewers are loaded at a time into the skewer loading section, the skewer can be aligned and conveyed by the alignment conveying means.

  In the skewer aligning device, the partition plate is swingable between the restriction position and the allowable position about an axis parallel to the width direction of the alignment table, and the partition plate swings. By doing so, it is preferable that the gap between the tip in the extending direction of the partition plate extending from the axis and the bottom surface of the skewer insertion portion is changed.

  In the above configuration, the gap between the tip of the divider plate and the bottom surface of the skewer throwing portion is a predetermined dimension or less (or the gap is eliminated) in a state where the divider plate is arranged at the restricting position, so that the skewer throwing portion side The skewer movement from the to the alignment table will be restricted. In addition, the gap between the tip of the partition plate and the bottom surface of the skewer insertion portion is larger than a predetermined size in a state where the partition plate is arranged at the allowable position, so that the skewer moves from the skewer insertion portion side to the alignment table. Will be allowed.

In this configuration, the partition plate swings along the inclination direction on the bottom surface of the skewer insertion portion. Therefore, when the partition plate swings between the regulation position and the swing position, the skewer in the skewer insertion portion is skewed. It will be shaken in the inclination direction of the bottom surface of the input part.
Therefore, even if the skewer thrown into the skewer throwing portion stays at the upper end side in the inclination direction of the bottom surface due to friction with the bottom surface of the skewer throwing portion, or the bottom surface being a gentle slope, The skewer can be guided from the upper end side in the inclination direction of the bottom surface to the lower end side by the shaking of the skewer by the partition plate described above. That is, it is possible to automatically eliminate the staying of the skewer in the skewer feeding unit.

  In addition, in the state immediately after the skewer is inserted into the skewer insertion part, even if the skewer direction (the longitudinal direction of the skewer) is not aligned, the skewer orientation is aligned by the skewing of the skewer by the partition plate described above. The direction of the skewer can be corrected so as to approach the width direction. As a result, the skewer can be supplied from the skewer insertion portion to the alignment table in a state in which the inclination angle of the skewer in the longitudinal direction with respect to the width direction of the alignment table is small. Can be arranged.

  Further, when the skewer is supplied from the skewer insertion unit to the alignment table in a state where the inclination angle of the skewer in the longitudinal direction with respect to the width direction of the alignment table is large, the skewer is sandwiched between the partition plate and the bottom surface of the skewer insertion unit. However, in the above configuration, the skew angle of the skewer supplied from the skewer loading unit to the alignment table is small, and the skew angle in the longitudinal direction of the skewer is reduced. Becomes difficult to be sandwiched between the gaps, and the skewers can be smoothly supplied to the alignment table.

  Further, in the skewer aligning device, the bottom surface of the skewer throwing portion has a first inclined surface that forms an upper end side in the inclination direction and a lower end side in the inclination direction, and has a larger inclination angle with respect to the horizontal plane than the first inclined surface. The front end portion of the partition plate is inclined to the front side in the swing direction of the partition plate from the lower end side in the tilt direction of the bottom surface toward the upper end side with respect to the base end portion of the partition plate. It is preferable that a base end portion of the partition plate is positioned above the first inclined surface, and a tip end portion of the partition plate is positioned below the first inclined surface.

  In the above configuration, by setting the inclination angle of the first inclined surface to be gentler than the second inclined surface located on the alignment table side, even if a large number of skewers are inserted in the skewer insertion portion, It is possible to suppress the weight of the skewer deposited on the inclined surface from being applied to the skewer deposited on the second inclined surface. Therefore, the weight of the skewer in the skewer insertion portion applied to the partition plate is also reduced, and the driving force for swinging the partition plate can be kept small.

Furthermore, in the above configuration, by setting the angle of the front end portion of the partition plate to the second inclined surface at a right angle or an angle close thereto, when the partition plate is swung forward in the swing direction, The skewers deposited on the two inclined surfaces can be efficiently pushed up to the upper side in the inclination direction of the second inclined surface.
Since the base end portion of the partition plate is tilted rearward in the swinging direction of the partition plate from the tip portion of the partition plate, the angle of the tip portion of the partition plate with respect to the second inclined surface is set as described above. In this state, the angle of the base end portion of the partition plate with respect to the first inclined surface can be set to a right angle or an angle close thereto. Further, since the base end portion of the partition plate is located above the first inclined surface, it is deposited on the first inclined surface when the partition plate is swung forward in the swing direction. It is possible to efficiently push the skewer up to the upper side in the inclination direction of the first inclined surface.

  Therefore, in the above configuration, even when the bottom surface of the skewer insertion portion is configured by two inclined surfaces having different angles, when the partition plate is swung between the restricting position and the swinging position, the second tilting is performed. The skewer deposited on the surface can be efficiently shaken in the inclination direction of the second inclined surface, and at the same time, the skewer deposited on the first inclined surface can be efficiently shaken in the inclination direction of the first inclined surface. .

  Furthermore, in the skewer aligning device, it is preferable that the leading end in the extending direction of the partition plate facing the bottom surface of the skewer insertion portion is formed of an elastic member that can be elastically deformed.

In this configuration, as described above, the skewer is supplied from the skewer insertion unit to the alignment table in a state where the inclination angle of the skewer in the longitudinal direction with respect to the width direction of the alignment table is large. Even if it is sandwiched between the bottom surface of the part, it is possible to prevent the skewer from being damaged by elastically deforming the tip of the partition plate. That is, the skewer can be protected.
Moreover, when the skewer is sandwiched, the tip of the partition plate is elastically deformed, so that the stress applied to the partition plate, the motor that drives the partition plate, or the transmission mechanism that transmits the driving force of the motor to the partition plate can be reduced. It is also possible to protect the skewer alignment device.

  Further, in the skewer alignment apparatus, the partition plate is configured by sequentially stacking a metal plate and an elastically deformable elastic plate from the allowable position side to the restriction position side, and the metal plate and the The elastic plate may be fixed only at the base end portion of the partition plate, and the elastic plate may protrude in the extending direction of the partition plate from the metal plate. In other words, the front end of the partition plate in the extending direction may be constituted only by the elastic plate.

In this configuration, when the skewer is sandwiched between the partition plate and the bottom surface of the skewer throwing portion, the skewer is sandwiched between the elastic plate and the bottom surface of the skewer throwing portion. Similarly, the tip of the elastic plate is elastically deformed to protect the skewer or skewer aligning device.
By the way, when the partition plate is moved from the allowable position to the restricting position, the skewer is sandwiched between the partition plate (elastic plate) and the bottom surface of the skewer insertion portion, and if the force to sandwich the skewer is excessively strong, It becomes impossible to move from the allowable position to the restricted position.

On the other hand, in the above configuration, since only the base end portion in the extending direction of the elastic plate is fixed to the metal plate, the middle portion in the extending direction of the elastic plate is elastically deformed, so that the distal end portion of the elastic plate It is possible to move only the metal plate from the restricting position toward the permissible position while remaining on the restricting position side. That is, even if the skewer is sandwiched with an excessively strong force, the swinging of the partition plate is not hindered, and it is possible to prevent stress from being applied to the motor and transmission mechanism that drive the partition plate. Therefore, it is possible to further protect the skewer alignment apparatus.
In addition, in the state where the midway part of the elastic plate in the extending direction is elastically deformed as described above, the elastic force based on the elastic deformation of the midway part of the elastic plate is applied to the tip part of the elastic plate remaining on the regulation position side. However, it acts in the direction from the restriction position side to the allowable position side. That is, it becomes possible to automatically release the sandwiching of the skewer, and the handling of the skewer aligning device is further facilitated.

  In the skewer aligning device, the alignment transport surface may have an upward inclined surface that is inclined upward from the base end portion in the extending direction toward the distal end side.

In this configuration, a force from the leading end side in the extending direction of the alignment conveying surface to the base end side acts on the skewer supplied from the skewer loading unit to the alignment table as the partition plate moves. . For this reason, it can suppress that the skewer supplied to the alignment stand from the skewer insertion part flows into the front-end | tip part side of an alignment conveyance surface rather than the alignment conveyance means.
Further, in this configuration, the skewer urged by the aligning / conveying means to the front end portion in the extending direction of the aligning / conveying surface on the upward inclined surface forming the base end portion of the aligning / conveying surface is also aligned and conveyed by its own weight. A force from the distal end side in the extending direction of the surface toward the proximal end side acts. Accordingly, the plurality of skewers are continuously urged by the aligning / conveying means, so that the skewers can be aligned with their own weight without gaps on the upper inclined surface forming the base end portion of the aligning / transporting surface.

Further, in the skewer alignment apparatus, the alignment transport surface is connected to the upper inclined surface and an end portion of the upper inclined surface on the front end side of the alignment transport surface, and on the front end side of the alignment transport surface. It is even better if it is composed of a downwardly inclined surface that inclines downward as it goes.
That is, in this skewer alignment apparatus, the base end portion in the extending direction of the alignment transport surface is constituted by an upper inclined surface, and the tip end portion of the alignment conveyance surface is constituted by a lower inclined surface. It has a mountain-shaped inclined surface. Further, the lower end of the downward inclined surface (the tip in the extending direction of the alignment conveyance surface) is a skewer discharge port for discharging the aligned skewers from the skewer alignment device in the order of alignment.

  In the above configuration, when the skewer aligned on the upper inclined surface sequentially passes through the connecting portion of the upper inclined surface and the lower inclined surface (the top of the angled inclined surface), the skewer is placed on the lower inclined surface by its own weight. It slides down to the front end side of the alignment conveyance surface. And the plurality of skewers that have slipped down may be aligned from the lower end of the lower inclined surface toward the upper end side, but the biasing force of the alignment conveying means does not act on the skewers aligned on the lower inclined surface, or The biasing force of the aligning / conveying means acting on the skewers aligned on the downward inclined surface is weakened. Therefore, it is possible to prevent a disorder in the alignment state of the skewers aligned on the alignment conveyance surface.

Further, in the skewer alignment apparatus, the skewer is a gun skewer in which a flat plate-shaped gripping portion that is wider than the skewer bar portion is formed at one end portion in the longitudinal direction of the skewer bar portion that pierces the dumpling. In addition, at least a part of the end surface of the grip portion extending from the outer peripheral surface of the skewer bar portion is an inclined end surface that is inclined from the other end side in the longitudinal direction of the skewer bar portion toward the one end side,
The alignment table is formed with an insertion groove that is recessed from the alignment conveyance surface and accommodates the grip portion of the gun skewer,
The inner surface of the insertion groove extending from the bottom surface of the insertion groove to the alignment conveyance surface is inclined with respect to the bottom surface of the insertion groove and the alignment conveyance surface, and the skewer bar portion is brought into surface contact with the alignment conveyance surface. In this state, it is preferable that an inclined inner side surface that makes the inclined end surface of the grip portion come into surface contact is formed.

In this configuration, it is possible to suppress or prevent the gun skewer from rotating in a plane along the alignment conveyance surface in a state where the gripping portion of the gun skewer is accommodated in the insertion groove and the skewer bar portion is in surface contact with the alignment conveyance surface.
In addition, the said structure is especially effective when the alignment conveyance surface has a downward inclined surface. That is, by suppressing or preventing the rotation of the gun skewer that slides down one by one on the lower inclined surface, the direction of the gun skewer that has slid down on the lower inclined surface can be ensured at the lower end side of the lower inclined surface. Can be matched in the width direction.

  According to the present invention, even if a large number of skewers are simultaneously loaded into the skewer loading portion, the skewer can be aligned and conveyed by the alignment conveying means. Therefore, it is possible to easily handle the skewer aligning apparatus and the dumpling manufacturing machine equipped with the skewer by reducing the number of times the skewer is loaded into the skewer loading unit.

It has a supporting guide surface. More specifically, the gun skewer 100 arranged on the skewer push-out guide 7A has a plate shape or a rod shape on the front side in the longitudinal direction of the gun skewer 100 from the gripping portion 100b side to the skewer tip portion 100c side. It is positioned by the guide surface of the skewer extrusion guide 7A so that the dumpling dough is located.

The skewer separating plate 7B separates the skewer from the skewer conveying unit 6 described later and guides the skewer toward the skewer extrusion guide 7A, and is inclined downward from the skewer conveying unit 6 toward the skewer extrusion guide 7A. Is provided. That is, the upper end of the skewer separating plate 7B is in contact with the skewer drum 91 that constitutes the skewer conveying unit 6, and the lower end of the skewer separating plate 7B is in contact with the guide surface of the skewer extrusion guide 7A.

Due to the grooves of the round roll 8A and the round roll receiver 8B, a ball unit dumpling is placed between the round roll 8A and the round roll receiver 8B in the circumferential direction of the outer peripheral surface of the round roll 8A based on the rotation of the round roll 8A. A molding passage is defined which is rounded while passing.

Next, the structure of the skewer alignment part 5 and the skewer conveyance part 6 for supplying the gun skewer 100 to the skewer extrusion part 7 mentioned above is demonstrated.
As shown in FIGS. 2 and 3, the skewer alignment unit 5 is attached to the outside of the housing 9, and as shown in FIGS. 2 and 3, the skewer insertion unit 21, the alignment table 22, the alignment transport roller 23, the sweep back roller 24, and the partition plate 25. And mainly.

The skewer throwing portion 21 is formed in a box shape that is open so that the gun skewer 100 can be thrown from above, and its bottom surface 26 is disposed so as to be inclined with respect to a horizontal plane. Further, the skewer insertion portion 21 is formed so as to open to the lower end side in the inclination direction of the bottom surface 26, and an alignment table 22 described later is connected to the lower end in the inclination direction of the bottom surface 26.

And two inclined surfaces 26b.

  Furthermore, the width dimension of the bottom face 26 orthogonal to the inclination direction of the bottom face 26 of the skewer throwing portion 21 is set to be slightly larger than the longitudinal dimension of the gun skewer 100. Thereby, the gun skewer 100 can be thrown into the skewer throwing part 21 so that the longitudinal direction of the gun skewer 100 coincides with the width direction of the skewer throwing part 21. In the illustrated example, the width of the second inclined surface 26b is set to be narrower than the width of the first inclined surface 26a depending on the shape of a pair of side plates 28, 28 described later. There is nothing.

The skewer insertion portion 21 is formed with an insertion groove 27 that is recessed from the bottom surface 26 and accommodates the grip portion 100 b of the gun skewer 100. The insertion groove 27 is formed at one end portion of the bottom surface 26 in the width direction, and is formed so as to extend over the inclined direction of the bottom surface 26. The depth dimension of the insertion groove 27 is set to be substantially equal to or larger than the width dimension of the portion of the gripping part 100b formed in a flat plate shape and protruding from the skewer bar part 100a.
By forming the insertion groove 27, the skewer bar portion 100 a of the gun skewer 100 can be brought into surface contact with the bottom surface 26 of the skewer insertion portion 21, and the posture of the gun skewer 100 can be stabilized. Further, since the insertion groove 27 is formed, the gripping portion 100b side of the gun skewer 100 faces the one end side in the width direction of the bottom surface 26 (the skewer bar portion 100a side of the gun skewer 100 is in the width direction of the bottom surface 26). The orientation of the gun skewer 100 to be inserted into the skewer insertion portion 21 can be promoted so that it faces the other end side of the gun.

And the height dimension of a pair of side plates 28 and 28 of the skewer insertion part 21 standingly arranged in the width direction both sides of the bottom face 26, and the skewer insertion part 21 standingly arranged in the inclination direction upper end part of the bottom face 26 The height dimension of the end plate 29 is set to such an extent that the gun skewer 100 placed in the skewer throwing portion 21 and deposited on the bottom surface 26 does not fall out from the skewer throwing portion 21. In the present embodiment, the height dimension of the pair of side plates 28, 28 on both sides of the second inclined surface 26b is set higher than the height dimension of the pair of side plates 28, 28 on both sides of the first inclined surface 26a. ing.
In addition, in the illustrated example, the pair of side plates 28 and 28 of the skewer insertion portion 21 are formed integrally with a pair of side plates 32 and 32 of the alignment table 22 described later, but the present invention is not limited thereto. For example, only a part of the pair of side plates 28, 28 of the skewer insertion part 21 may be formed integrally with the pair of side plates 32, 32 of the alignment table 22, or separately from the pair of side plates 32, 32 of the alignment table 22. May be formed.

The aligning table 22 includes an aligning and conveying surface 31 connected to the lower end in the inclination direction of the second inclined surface 26 b (bottom surface 26) of the skewer loading unit 21, and an aligning and conveying surface parallel to the width direction of the bottom surface 26 of the skewer loading unit 21. It is formed in a box shape having a pair of side plates 32, 32 erected at both ends in the width direction of 31.
In the illustrated example, the width dimension of the alignment conveyance surface 31 (the interval between the pair of side plates 32, 32) matches the width dimension of the second inclined surface 26b of the skewer loading portion 21, but is not limited thereto. However, it is only necessary to set the gun skewer 100 on the alignment conveyance surface 31 so that at least the longitudinal direction of the gun skewer 100 coincides with the width direction of the alignment conveyance surface 31. Therefore, the width dimension of the alignment conveyance surface 31 may be set narrower than the width dimension of the second inclined surface 26b, for example.

The alignment conveyance surface 31 is orthogonal to the width direction and extends in a direction (X direction in FIG. 2) that coincides with the inclination direction of the skewer insertion portion 21 in a plan view (FIG. 2).
The alignment conveying surface 31 includes an upper inclined surface 33 that is inclined upward as it goes from the proximal end portion in the extending direction of the alignment conveying surface 31 located on the skewer loading portion 21 side toward the distal end portion side, and the upper inclined surface 33. Among them, a lower inclined surface 34 is connected to the end portion on the front end side of the alignment conveyance surface 31 and inclines downward from the base end side in the extending direction of the alignment conveyance surface 31 toward the front end side. ing. That is, the alignment conveyance surface 31 is formed in a mountain-shaped inclined surface (mountain-shaped inclined surface) whose apex is a middle portion in the extending direction in a side sectional view (FIG. 3).

In the present embodiment, the upper inclined surface 33 and the second portion of the skewer loading portion 21 are arranged at the lower end portion (the base end portion in the extending direction of the alignment conveying surface 31) of the upper inclined surface 33 positioned on the skewer loading portion 21 side. A curved surface 35 that smoothly connects the inclined surface 26b is formed. In addition, in the example of illustration, although the curved surface 35 is united with the 2nd inclined surface 26b of the skewer insertion part 21, it does not restrict to this.
By forming the curved surface 35, the gun skewer 100 can be smoothly moved from the skewer insertion portion 21 side toward the alignment table 22 side. In other words, the gun skewer 100 is restrained from staying at the boundary portion between the bottom surface 26 of the skewer loading portion 21 and the alignment conveyance surface 31 of the alignment table 22.

The alignment table 22 is formed with an insertion groove 36 that is recessed from the alignment conveyance surface 31 and accommodates the gripping portion 100 b of the gun skewer 100, similar to the insertion groove 27 of the skewer insertion portion 21.
As shown in FIGS. 2 to 4, the insertion groove 36 is formed at one end portion in the width direction of the aligning / transporting surface 31, and is formed so as to extend in the extending direction of the aligning / transporting surface 31. The depth dimension of the insertion groove 36 in FIG. 4 is set so that the grip portion 100b that has entered the insertion groove 36 contacts the bottom surface 36a of the insertion groove 36, but may be set so as not to contact. .

The entire inner surface of the insertion groove 36 extending from the bottom surface 36a of the insertion groove 36 to the alignment conveyance surface 31 on which the skewer bar portion 100a is disposed is inclined with respect to the bottom surface 36a of the insertion groove 36 and the alignment conveyance surface 31. It is formed as a side surface 36b. The inclined inner side surface 36 b is formed over the extending direction of the alignment conveyance surface 31. Further, the inclined inner side surface 36b is curved so as to bulge outward.
The shape of the inclined inner side surface 36b corresponds to the shape of the inclined end surface 100d of the grip portion 100b constituting the gun skewer 100 (see FIG. 10). More specifically, the inclined inner side surface 36b is an inclined end surface of the holding portion 100b in a state where the holding portion 100b of the gun skewer 100 is accommodated in the insertion groove 36 and the skewer bar portion 100a is in surface contact with the alignment conveyance surface 31. 100d is formed to be in surface contact.

  In the present embodiment, the alignment conveyance surface 31 and the inclined inner surface 36 b of the insertion groove 36 are formed by the same plate-shaped member 37, and the bottom surface 36 a of the insertion groove 36 is formed by a member separate from the plate-shaped member 37. Is formed. Therefore, in the alignment table 22 of the present embodiment, by preparing the plate-like members 37 having various shapes and sizes, it is possible to correspond to the various types of gun skewers 100.

As described above, in the alignment table 22, the gun skewers 100 are arranged in a line in the extending direction of the alignment conveyance surface 31 so that the longitudinal direction of the gun skewers 100 coincides with the width direction of the alignment conveyance surface 31. It becomes possible. Then, the lower end of the lower inclined surface 34 (the front end in the extending direction of the alignment conveyance surface 31) is aligned and conveyed from the base end portion of the alignment conveyance surface 31 toward the distal end portion by a biasing force of the alignment conveyance roller 23 described later. The skewer skewer 100 serves as a skewer discharge port for discharging the gun skewer 100 from the alignment table 22 in the order of alignment.
In this aligning table 22, the surfaces that can be contacted by the gun skewer 100, such as the aligning and conveying surface 31, the inner surface of the pair of side plates 32 and 32, the inner surface of the insertion groove 36, and the like are set to have a small coefficient of friction. For example, it may be formed of a synthetic resin plate (sliding member) or sheet (sliding member) having a low friction coefficient such as a silicon plate or a fluororesin sheet.

As shown in FIGS. 2, 3, and 5, the alignment transport roller 23 is provided at the lower end portion (the base end portion in the extending direction of the alignment transport surface 31) of the upper inclined surface 33 positioned on the skewer insertion portion 21 side. A cylindrical or columnar roller main body 41 disposed below the upper inclined surface 33 and a biasing protrusion 42 protruding from the outer peripheral surface of the roller main body 41 are provided.
The roller body 41 is attached to the alignment table 22 so that its axis coincides with the width direction of the upper inclined surface 33 and is rotatable about the axis. The direction in which the roller body 41 is rotationally driven is such that a portion of the outer peripheral surface of the roller body 41 facing the upper inclined surface 33 moves in a direction from the lower end side to the upper end side of the upper inclined surface 33. 3 and 5 are set in the counterclockwise direction.

  The biasing protrusion 42 protrudes upward from the upper inclined surface 33 in accordance with the rotational position of the roller body 41. Here, the length of the urging protrusion 42 protruding from the upper inclined surface 33 is set to be equal to the thickness dimension or the diameter dimension of the skewer bar portion 100 a disposed on the upper inclined surface 33. As a result, the skewer bar portion 100a of one gun skewer 100X arranged in surface contact directly above the upper inclined surface 33 is moved from the lower end side of the upper inclined surface 33 by the biasing protrusion 42 as the roller body 41 rotates. When biased toward the upper end side, the other skewer skewer 100Z deposited on the upper side of the one gun skewer 100X is prevented from being biased by the biasing protrusion 42.

Further, a rounded chamfered portion 42 a is formed at a corner portion of the front end portion in the protruding direction of the biasing protrusion 42 that is positioned on the front side in the rotational direction of the roller body 41. Even if the length of the urging protrusion 42 protruding from the upper inclined surface 33 is set to be slightly larger than the thickness dimension and the diameter dimension of the skewer bar portion 100a, the chamfered portion 42a is formed. Thus, it is possible to prevent the other skewer skewer 100Z deposited on the upper side of the one skewer skewer 100X from being biased by the biasing protrusion 42. More specifically, even if another gun skewer 100Z deposited on the upper side of one gun skewer 100X comes into contact with the chamfered portion 42a, the force for urging the other gun skewer 100Z is weak. The skewer 100Z is not pushed from the lower end side of the upper inclined surface 33 toward the upper end side.
In the illustrated example, a plurality of urging protrusions 42 are arranged at equal intervals in the circumferential direction of the roller body 41. However, for example, they may be arranged at unequal intervals, or only one may be provided.

  A plurality (two in FIG. 2) of the alignment conveying rollers 23 are arranged at intervals in the width direction of the upper inclined surface 33. Further, the plurality of aligning and conveying rollers 23 are configured such that the circumferential positions of the biasing protrusions 42 coincide with each other, and the rotation of the roller body 41 is synchronized with each other. Therefore, the skewer bar portion 100a of one gun skewer 100 arranged in surface contact directly above the upper inclined surface 33 is simultaneously pushed out by the urging protrusions 42 of the plurality of alignment conveying rollers 23. As a result, one gun skewer 100 is urged from the lower end side to the upper end side of the upper inclined surface 33 in a state where the posture is adjusted so that the longitudinal direction thereof coincides with the width direction of the upper inclined surface 33. It will be.

Accordingly, the plurality of alignment transport rollers 23 described above adjust the posture of the gun skewer 100 arranged on the alignment transport surface 31 one by one so that the longitudinal direction of the gun skewer 100 is orthogonal to the extending direction of the alignment transport surface 31. At the same time, an aligning / conveying means for urging the skewer skewers 100 arranged on the aligning / conveying surface 31 one by one toward the leading end side in the extending direction of the aligning / conveying surface 31 is configured.
However, when the roller main body 41 and the urging protrusion 42 are formed wide so as to extend in the width direction of the alignment conveyance surface 31, the alignment conveyance means can be configured by only one alignment conveyance roller 23.

As shown in FIGS. 2 and 3, the sweep-back roller 24 is located at the upper end side of the upper inclined surface 33 (the tip end side in the extending direction of the aligned conveying surface 31) with respect to the upper inclined surface 33 than the aligned conveying roller 23. It is arranged above the upper inclined surface 33 so that a gap having the same dimension as the thickness of the skewer bar portion 100a is formed therebetween.
The sweep back roller 24 is configured as a brush roller in which fibers made of resin or the like are planted on the outer peripheral surface of a cylindrical or columnar roller body 51. The roller body 51 is attached to the alignment table 22 so that its axis coincides with the width direction of the upper inclined surface 33 and is rotatable about the axis. The direction in which the roller body 51 is rotationally driven is such that the portion of the outer peripheral surface of the roller body 51 facing the upper inclined surface 33 moves in the direction from the upper end side to the lower end side of the upper inclined surface 33. 3 is set in the counterclockwise direction.

  A plurality (three in the illustrated example) of the sweep back rollers 24 are arranged at intervals in the width direction of the upper inclined surface 33. Further, the roller bodies 51 of the plurality of sweepback rollers 24 rotate in synchronization with each other. One sweep-back roller 24 is disposed above the insertion groove 36 formed at one end in the width direction of the upper inclined surface 33, but its height position is the same as the other sweep-back rollers 24. Is set.

The plurality of sweep-back rollers 24 align and convey another gun skewer 100 deposited on the gun skewer 100 that is aligned and conveyed toward the tip end side of the alignment and conveyance surface 31 by the biasing force of the alignment and conveyance roller 23 described above. A sweep back means for sweeping back to the base end side of the surface 31 is configured. That is, the plurality of sweep-back rollers 24 serve to prevent being aligned and transported from the base end portion to the distal end side of the alignment transport surface 31 in a state where the plurality of gun skewers 100 are deposited on the alignment transport surface 31. Plays.
In addition, as long as the roller main body 51 of the sweep back roller 24 is formed wide so as to extend in the width direction of the alignment conveyance surface 31, the sweep back unit may be configured by one sweep back roller 24.

As shown in FIGS. 3 and 6, the partition plate 25 is disposed between the skewer throwing portion 21 and the alignment table 22 described above, and supports the gun skewer 100 deposited on the bottom surface 26 of the skewer throwing portion 21. Is.
The partition plate 25 swings with respect to the skewer loading unit 21 and the alignment table 22 around an axis (shaft portion 61) parallel to the width direction of the bottom surface 26 of the skewer loading unit 21 and the alignment conveyance surface 31 of the alignment table 22. It is mounted movably. The width dimension of the partition plate 25 attached in this way is set to be substantially the same as the width dimension of the bottom surface 26 of the skewer loading portion 21 and the alignment conveyance surface 31 of the alignment table 22.
Further, the shaft portion 61 is located above the bottom surface 26 of the skewer throwing portion 21, and the partition plate 25 extends downward from the shaft portion 61 side toward the second inclined surface 26 b of the skewer throwing portion 21. . Thereby, the front-end | tip of the extension direction of the partition plate 25 is arrange | positioned facing the 2nd inclined surface 26b. Further, the base end portion of the partition plate 25 in the extending direction is located above the first inclined surface 26a of the skewer insertion portion 21, and the tip end portion of the partition plate 25 is located below the first inclined surface 26a. Yes.

And the front-end | tip part of the partition plate 25 is inclined rather than the base end part to the rocking | fluctuation direction front side of the partition plate 25 which goes to the upper end side from the inclination direction lower end side of the bottom face 26 of the skewer insertion part 21. FIG. In addition, in this embodiment, the surface which faces the skewer insertion part 21 side among the partition plates 25 is curving so that it may become depressed toward the alignment stand 22 side from the skewer insertion part 21 side. A relative position between the portion and the tip portion is determined.
Further, the orientation of the partition plate 25 with respect to the bottom surface 26 of the skewer throwing portion 21 is set so that the angle of the tip of the partition plate 25 with respect to the second inclined surface 26b of the skewer throwing portion 21 is a right angle or an angle close thereto. Yes. Thereby, the angle of the base end part of the partition plate 25 located above the 1st inclined surface 26a of the skewer insertion part 21 is a right angle with respect to the 1st inclined surface 26a, or an angle close | similar to this.

The partition plate 25 is configured by laminating an elastic plate 63 that can be elastically deformed like a rubber plate and a metal plate 62 having higher rigidity than the elastic plate 63, and the elastic plate 63 and the metal plate 62. Is fixed only at the base end portion of the partition plate 25. However, when no external force is applied to the partition plate 25, the elastic plate 63 and the metal plate 62 are in contact with each other without any gap. Further, the elastic plate 63 protrudes in the extending direction of the partition plate 25 from the metal plate 62. In other words, the leading end of the partition plate 25 in the extending direction is constituted only by the elastic plate 63.
In the partition plate 25 configured as described above, the elastic plate 63 faces the skewer insertion portion 21 side (the upper end side in the inclination direction of the second inclined surface 26b), and the metal plate 62 has the alignment table 22 side (second It is arranged so as to face the lower end side of the inclined surface 26b.

Then, as shown in FIG. 6, the partition plate 25 has a restriction position P <b> 1 for restricting the movement of the gun skewer 100 from the skewer insertion portion 21 side to the alignment table 22 and an allowable position P <b> 2 for allowing the gun skewer 100 to move. Can swing between the two.
More specifically, the partition plate 25 is moved so that the tip end of the partition plate 25 in the extending direction moves in the tilt direction of the second inclined surface 26b by the swinging motion, and the tip of the partition plate 25 and the skewer The insertion portion 21 is attached to the skewer insertion portion 21 and the alignment table 22 so that the gap with the second inclined surface 26b changes.

  The restriction position P <b> 1 described above indicates the swing position of the partition plate 25 where the gap between the partition plate 25 and the second inclined surface 26 b is large enough not to pass the gun skewer 100. The gap g1 between the partition plate 25 and the second inclined surface 26b at the restriction position P1 is at least 0.0 (mm) ≦ g1 ≦ 1.5 × t1 with the thickness (or diameter) of the skewer bar portion 100a being t1. However, considering the friction between the elastic plate 63 and the second inclined surface 26b, the gap g1 is preferably set to be larger than 0.0 (mm). Further, it is more preferable that the gap g1 is set to about “1.5 × t1” so that the gun skewer 100 is not caught between the elastic plate 63 and the second inclined surface 26b. Since the direction of the gun skewer 100 deposited in the skewer throwing portion 21 is complicated, even if the gap g1 at the restricting position P1 is set to be equal to or greater than the thickness t1 of the skewer rod portion 100a, the gun skewer 100 remains in the skewer throwing portion. There is no movement from the 21 side to the alignment table 22 side.

On the other hand, the allowable position P2 of the partition plate 25 described above indicates the swing position of the partition plate 25 where the gap between the partition plate 25 and the second inclined surface 26b is large enough to allow the gun skewer 100 to pass through. ing. The gap g2 between the partition plate 25 and the second inclined surface 26b at the allowable position P2 may be, for example, g1 <g2 ≦ 2.5 × t1. Note that the gap g2 is set to about “2.5 × t1” so that the gun skewer 100 can be more reliably moved from the skewer insertion portion 21 side to the alignment table 22 side in a state where the partition plate 25 is arranged at the allowable position P2. More preferably, it is set.
In the present embodiment, the moving direction of the partition plate 25 from the allowable position P2 to the restricting position P1 is set to the direction from the lower end side to the upper end side in the inclination direction of the second inclined surface 26b. Conversely, the moving direction of the partition plate 25 from the restricting position P1 to the allowable position P2 is set to a direction from the upper end side to the lower end side in the tilt direction of the second inclined surface 26b.

If it demonstrates in detail about the partition plate 25 of this embodiment, the axial part 61 used as the rocking | swiveling center of the partition plate 25 will be arrange | positioned above the sweep back roller 24. FIG. The partition plate 25 and the shaft portion 61 are integrally fixed by a flat offset plate 64. By forming the offset plate 64, the entire partition plate 25 is positioned closer to the skewer insertion portion 21 than the sweep back roller 24 without interfering with the sweep back roller 24.
Further, the mechanism for swinging the partition plate 25 is constituted by an eccentric cam 65 that supports the offset plate 64 positioned between the base end portion of the partition plate 25 and the shaft portion from below. The eccentric cam 65 is formed in a columnar shape or a cylindrical shape, and rotates about a rotation axis shifted from the central axis of the outer peripheral surface thereof. The central axis and the rotational axis of the eccentric cam 65 are both parallel to the width direction of the skewer insertion portion 21 and the alignment table 22.

  As shown in FIG. 3, in the skewer alignment unit 5 of the present embodiment, the above-described eccentric cam 65, the above-described alignment conveyance roller 23, and the sweep are driven by the driving force of the same drive motor 71 (for example, an electric motor) provided for this. The return roller 24 is driven to rotate. Note that the endless belt 73 wound between the driving pulley 72 of the driving motor 71 and the conveying roller pulley 43 provided on the back side of the alignment conveying roller 23, and on the back side of the driving pulley 72 and the sweep back roller 24. The driving force of the drive motor 71 is transmitted to the alignment transport roller 23 and the sweep back roller 24 by an endless belt 74 wound between the provided sweep back roller pulley 53. Further, the driving force of the driving motor 71 is transmitted to the eccentric cam 65 via the alignment conveying roller 23 by the endless belt 75 wound between the conveying roller pulley 43 and the cam pulley 66 provided on the back side of the eccentric cam 65. Is done.

The skewer guide plates 81 and 82 are provided above the upper inclined surface 33 and the lower inclined surface 34 with a gap substantially equal to the thickness (t1) of the skewer bar portion 100a.
The skewer guide plate 81 on the upper inclined surface 33 is attached to the pair of side plates 32 and 32 via a support shaft 83 disposed at a position spaced apart from the sweep back roller 24 to the upper end side of the upper inclined surface 33. ing. The skewer guide plate 81 extends from the support shaft 83 to a position adjacent to the sweepback roller 24, and prevents the gun skewer 100 from floating immediately after passing through the sweepback roller 24.

On the other hand, the skewer guide plate 82 on the lower inclined surface 34 extends from the vicinity of the upper end to the lower end of the lower inclined surface 34, and in particular, the gun skewer 100 aligned in the lower end of the lower inclined surface 34 has the lower inclined surface 34. To prevent it from floating up. The skewer guide plate 82 is attached to the alignment table 22 via a support frame 84 suspended from the upper ends of the pair of side plates 32 and 32 and a suspension bolt 85 suspended from the support frame 84 toward the downward inclined surface 34. It is attached.
For the skewer guide plates 81 and 82, for example, a stainless steel plate or a synthetic resin plate excellent in slidability can be used. Further, the skewer guide plates 81 and 82 may be provided with linear rib protrusions or the like extending in the inclination direction of the upper inclined surface 33 or the lower inclined surface 34 in order to reduce friction.

Furthermore, the skewer alignment unit 5 of the present embodiment includes a photoelectric sensor 86 that detects the presence or absence of the gun skewer 100 at a predetermined position near the upper end of the downward inclined surface 34. It is possible to suitably employ various photoelectric sensors 86 that project detection light, for example, and detect the reflected light or transmitted light received by the light receiving unit.
And in the skewer alignment part 5 of this embodiment, when the gun skewer 100 is detected by this photoelectric sensor 86, operation | movement of the drive motor 71 is stopped based on this detection result. On the other hand, when the gun skewer 100 is no longer detected by the photoelectric sensor 86, the operation of the drive motor 71 is started based on the detection result.
In addition to the above-described configuration, the skewer alignment unit 5 may include a configuration such as a press plate described in Patent Document 1, for example.

As shown in FIGS. 2 and 3, the skewer transport unit 6 includes a skewer drum 91 provided inside the housing 9 so as to be adjacent to the above-described skewer alignment unit 5 (the lower end of the downward inclined surface 34). .
The skewer drum 91 is formed in a cylindrical shape or a columnar shape, and is rotatable about its axis. More specifically, the skewer drum 91 is rotationally driven in the counterclockwise direction indicated by the arrow in FIG.

The skewer drum 91 is formed with a plurality of skewer guide grooves 92 that are recessed from the outer peripheral surface and extend in the axial direction, and the plurality of skewer guide grooves 92 extends over the circumferential direction of the outer peripheral surface of the skewer drum 91. They are arranged at equal intervals.
The width dimension of the skewer guide groove 92 along the circumferential direction of the skewer drum 91 is equal to the width dimension (t1) of the skewer bar part 100a along the width direction of the grip part 100b of the gun skewer 100, or the skewer bar part 100a It is set slightly larger than the width dimension. That is, the skewer guide groove 92 is formed so that only the skewer bar portion 100a of the gun skewer 100 enters and the grip portion 100b does not enter.

The skewer drum 91 is formed with a plurality of circumferential grooves 93 and 94 that are recessed from the outer circumferential surface and extend in the circumferential direction of the outer circumferential surface.
The first circumferential groove 93 is formed at one end in the axial direction of the skewer drum 91, and the gripping part 100 b enters with the skewer bar part 100 a of the gun skewer 100 entering the skewer guide groove 92. is there. On the other hand, the second circumferential groove 94 is formed to be orthogonal to the skewer guide groove 92 described above, and the depth dimension thereof is set to be equal to that of the skewer guide groove 92. The second circumferential groove 94 is in contact with one end of the skewer separating plate 7B of the skewer pushing portion 7.

A portion that moves downward is arranged adjacent to the skewer extrusion guide 7A. Further, in this arrangement state, one end of the skewer separating plate 7 </ b> B of the skewer pushing portion 7 is in contact with the bottom surface of the second circumferential groove 94. Therefore, the skewer bar portion 100a of the gun skewer 100 conveyed from the skewer alignment portion 5 side to the skewer extrusion portion 7 side by the rotation of the skew drum 91 is extracted from the skewer guide groove 92 by the skewer separating plate 7B, and the gun skewer 100 can be transferred to the skewer extrusion guide 7A.
In addition to the configuration described above, the skewer transport unit 6 has a configuration described in, for example, Patent Document 1 (for example, a skewer guide plate that prevents the gun skewer 100 from being unintentionally detached from the skewer drum 91). You may have.

  And the dumpling manufacturing machine 1 of this embodiment includes a dough roll 11, a forming roll 4A, 4B, a round roll 8A, a skewer drum 91, and a skewer pushing mechanism 7C (motors for driving the skewer extrusion mechanism 7C) disposed in the housing 9. And a control unit (not shown) that controls the operation of the motor and the drive motor 71 of the skewer alignment unit 5. These motors and control units are provided in the housing 9, for example.

Next, a method for manufacturing a skewer dumpling with the dumpling manufacturing machine 1 having the above configuration will be described.
In the dumpling making machine 1, when dumpling dough is put into the dough hopper 2, the dough extruding unit 3 forms the dumpling dough into a plate shape or a rod shape and pushes it downward. When the dumpling dough arrives just before the forming rolls 4A and 4B, the gun skewer 100 supplied to the skewer pusher 7 is operated by a skewer pusher 7C by the operations of the skewer aligner 5 and the skewer feeder 6 described later. Is pushed out and pierced into the dumpling dough. The dumpling dough pierced with the gun skewer 100 is divided into a plurality of dumpling balls by the intermittently rotating molding rolls 4A and 4B, and sent to the lower round molding unit 10. In the round shape forming part 10, each dumpling ball is rounded and then discharged as a skewer dumpling.

Next, operations of the skewer alignment unit 5 and the skewer transport unit 6 will be described.
In the dumpling manufacturing machine 1 according to the present embodiment, as shown in FIG. 3, an operator inputs a large number of gun skewers 100... From the upper side of the skewer input part 21 toward the bottom surface 26 (mainly the first inclined surface 26 a). do it. Here, the orientation of the gun skewer 100 to be inserted is not limited as long as the skewer bar portion 100a is positioned approximately on the bottom surface 26 and the grip portion 100b is approximately positioned on the insertion groove 27. There is no need to prepare 100 fine postures. For example, the longitudinal direction of the gun skewer 100 thrown into the skewer throwing portion 21 may not coincide with the width direction of the bottom surface 26.

Many of the skewer skewers 100 thrown in this way try to move to the lower end side in the inclination direction of the bottom surface 26 by their own weight, but because the partition plate 25 is arranged on the lower end side in the inclination direction of the bottom surface 26, It accumulates on the bottom face 26 of the skewer throwing part 21. Here, since the bottom surface 26 of the skewer insertion portion 21 is constituted by the first inclined surface 26a having a small inclination angle and the second inclined surface 26b having a large inclination angle, the guns deposited on the first inclined surface 26a. The weight of the skewer 100 is prevented from being applied to the gun skewer 100 deposited on the second inclined surface 26b.
When the partition plate 25 swings between the restriction position P1 and the allowable position P2 in a state where the gun skewer 100 is thus deposited, the gun skewer 100 in the skewer throwing portion 21 is inclined to the bottom surface 26 of the skewer throwing portion 21. The direction of the gun skewer 100 in the skewer throwing portion 21 is corrected so as to approach the width direction of the skewer throwing portion 21 and the alignment table 22 by this shaking.

  Then, the partition plate 25 repeatedly moves between the restriction position P1 and the allowable position P2, so that the gun skewer 100 in the skewer insertion portion 21 is intermittently supplied toward the alignment table 22. More specifically, the gun skewer 100 in the skewer insertion portion 21 is placed on the curved surface 35 of the alignment table 22 from the second inclined surface 26b by its own weight in a state where the partition plate 25 is arranged at the allowable position P2. To the base end of the aligning / conveying surface 31 of the aligning table 22 (particularly on the aligning / conveying roller 23). In addition, adjustment of the supply amount of the gun skewer 100 per one time to the alignment table 22 is performed by adjusting the size of the gap g2 between the partition plate 25 and the bottom surface 26 of the skewer insertion portion 21 at the permissible position P2 and the regulation position P1. This can be done by appropriately controlling the speed at which the partition plate 25 swings between the allowable position P2. The supply amount of the gun skewer 100 per time may be adjusted so that the weight of the gun skewer 100 deposited on the alignment transport roller 23 does not become excessive.

In the gun skewer 100 supplied to the base end portion of the aligning / conveying surface 31 of the aligning table 22, the longitudinal direction of the gun skewer 100 is orthogonal to the extending direction of the aligning / conveying surface 31 as the plurality of aligning / conveying rollers 23 rotate. In such a state that the posture is adjusted, it is urged one by one toward the front end portion side in the extending direction of the alignment conveyance surface 31.
The gripping portion 100 b of the gun skewer 100 biased in this way is inserted into the insertion groove 36 of the aligning and conveying surface 31, and the skewer bar portion 100 a is in surface contact with the aligning and conveying surface 31. In addition, since the aligning and conveying surface 31 provided with the aligning and conveying roller 23 is an upward inclined surface 33, the plurality of biased gun skewers 100 have their base weights from the distal end side of the aligning and conveying surface 31 to the base end. Force toward the club side acts. Accordingly, the plurality of gun skewers 100 are aligned without gaps from immediately after the alignment transport roller 23 toward the upper inclined surface 33. Then, due to the urging force of the aligning and conveying roller 23, the plurality of gun skewers 100 are conveyed to the upper end side of the upper inclined surface 33 while maintaining this aligned state.

  If another gun skewer 100 is deposited on the gun skewer 100 that is aligned and conveyed in this way, the other gun skewer 100 is also conveyed above the upper inclined surface 33, but from the alignment conveying roller 23. In addition, as the sweep back roller 24 disposed on the upper end side of the upper inclined surface 33 rotates, the other gun skewer 100 is swept back to the lower end side of the upper inclined surface 33 with respect to the alignment conveying roller 23. Therefore, the skewer skewer 100 is not conveyed to the upper end side of the upper inclined surface 33 rather than the sweep back roller 24 in a state where the gun skewer 100 is deposited on the upper inclined surface 33.

When the gun skewer 100 aligned and conveyed by the urging force of the aligning and conveying roller 23 reaches the upper end of the upper inclined surface 33 (the top of the angled inclined surface), the gun skewer 100 is moved to the lower end side of the lower inclined surface 34 by its own weight. Slide down toward.
Here, when the transfer of the gun skewer 100 from the skewer alignment unit 5 to the skewer transfer unit 6 is not performed, or the transfer speed of the gun skewer 100 from the skewer alignment unit 5 to the skewer transfer unit 6 (the skewer drum 91 ) Is slower than the supply speed of the skewer skewer 100 from the upper inclined surface 33 to the lower inclined surface 34 (rotational speed of the alignment conveying roller 23), the plurality of gun skewers 100 are formed on the lower inclined surface 34. They are aligned from the lower end to the upper end side. Then, when the gun skewer 100 aligned with the downward inclined surface 34 reaches the installation location of the photoelectric sensor 86 as shown in FIG. 3, the operation of the drive motor 71 is stopped. That is, it is possible to prevent the gun skewer 100 from being excessively supplied to the lower inclined surface 34.

  As described above, the gun skewer 100 that has reached the lower end of the downward inclined surface 34 is sequentially transferred from the skewer alignment unit 5 to the skewer conveying unit 6 by the rotation of the skewer drum 91, and is conveyed toward the skewer pushing unit 7. When the skewer drum 91 further rotates, the gun skewer 100 on the skewer drum 91 is separated from the skewer drum 91 by the skewer separating plate 7B of the skewer pushing portion 7, and is delivered to the skewer pushing guide 7A.

  As described above, according to the dumpling production machine 1 according to the present embodiment, the skewer skewer 100 is intermittently supplied from the skewer throwing unit 21 to the alignment table 22, so that the skewer throwing unit 21 can be supplied at a time. Even if a large number of gun skewers 100 are introduced, the amount of gun skewers 100 deposited on the base end portion of the aligning and conveying surface 31 (particularly on the aligning and conveying roller 23) can be reduced. Therefore, the posture of the gun skewer 100 is adjusted, and the function of the alignment transport roller 23 that urges the gun skewer 100 toward the front end side of the alignment transport surface 31 can be prevented from being hindered by the weight of the gun skewer 100. That is, even if a large number of gun skewers 100 are loaded into the skewer loading unit 21 at a time, the guns skewer 100 can be aligned and conveyed by the alignment conveyance roller 23. In addition, the dumpling manufacturing machine 1 can be easily handled by reducing the number of times the gun skewer 100 is inserted into the skewer input unit 21.

Further, by swinging the partition plate 25, the gun skewer 100 thrown into the skewer throwing portion 21 is shaken in the inclination direction of the bottom face 26, so that the direction of the gun skewer 100 in the skewer throwing portion 21 is changed to the skewer throwing portion 21 or Correction can be made so as to approach the width direction of the alignment table 22. Therefore, the skewer skewer 100 can be supplied from the skewer insertion portion 21 to the alignment table 22 in a state in which the inclination angle of the longitudinal direction of the gun skewer 100 with respect to the width direction of the alignment table 22 is small. The posture of the skewer 100 can be adjusted easily and reliably.
Furthermore, since the inclination angle in the longitudinal direction of the gun skewer 100 supplied from the skewer throwing part 21 to the alignment table 22 becomes small, the gun skewer 100 is hardly sandwiched between the bottom surface 26 of the skewer throwing part 21 and the partition plate 25. Thus, the skewer skewer 100 can be smoothly supplied to the alignment table 22.

Further, since the gun skewer 100 in the skewer throwing portion 21 is shaken in the inclination direction of the bottom surface 26 by the swing of the partition plate 25, the gun skewer 100 in the skewer throwing portion 21 is in friction with the bottom surface 26 of the skewer throwing portion 21. Alternatively, even if the bottom surface 26 stays on the upper end side in the inclination direction of the bottom surface 26 due to the gentle slope, the gun skewer 100 is moved from the upper end side in the inclination direction of the bottom surface 26 to the lower end side by the above shaking. Can lead to. That is, the stay of the gun skewer 100 in the skewer throwing part 21 can be automatically eliminated.
In the present embodiment, the bottom surface 26 of the skewer throwing portion 21 is constituted by two inclined surfaces having different tilt angles, but the angle of the base end portion of the partition plate 25 with respect to the first inclined surface 26a of the skewer throwing portion 21 Is set to be a right angle or an angle close thereto, and the angle of the tip portion of the partition plate 25 with respect to the second inclined surface 26b of the skewer insertion portion 21 is set to be a right angle or an angle close thereto. .

For this reason, as shown in FIG. 7, when the partition plate 25 is swung so that the tip of the partition plate 25 moves from the lower end side in the inclination direction of the second inclined surface 26b toward the upper end side, the tip of the partition plate 25 is moved. By the portion, the gun skewer 100 deposited on the second inclined surface 26b can be efficiently pushed up to the upper end side in the inclination direction of the second inclined surface 26b. In addition, the gun skewer 100 deposited on the first inclined surface 26a can be efficiently pushed up to the upper end side in the inclination direction of the first inclined surface 26a by the base end portion of the partition plate 25. That is, both of the skewer skewers 100 deposited on the two inclined surfaces 26a and 26b having different inclination angles can be efficiently shaken.
If the partition plate 25 is a simple flat plate extending linearly from the shaft 61 side toward the second inclined surface 26b, the angle of the tip portion of the partition plate 25 with respect to the second inclined surface 26b is a right angle or If an angle close to this is set, the angle of the partition plate 25 with respect to the first inclined surface 26a is an angle greatly deviated from a right angle. For this reason, when the flat partition plate 25 is swung, the force to push up the gun skewer 100 deposited on the first inclined surface 26a to the upper end side in the inclination direction of the first inclined surface 26a is weakened. The skewer skewer 100 deposited on the inclined surface 26a cannot be shaken sufficiently.

Further, since the leading end of the partition plate 25 in the extending direction is composed only of an elastic plate, as shown in FIG. 8 (a), the inclination of the gun skewer 100Y in the longitudinal direction with respect to the alignment table 22 and the skewer insertion portion 21 is assumed. Even if the gun skewer 100Y is supplied from the skewer throwing portion 21 to the alignment table 22 in a state where the angle is large, the gun skewer 100Y is sandwiched between the partition plate 25 and the bottom surface 26 of the skewer throwing portion 21. Since the tip of the partition plate 25 is elastically deformed, the gun skewer 100Y can be prevented from being damaged. That is, it is possible to protect the steel skewer 100Y.
Further, when the gun skewer 100 is sandwiched, the tip of the partition plate 25 is elastically deformed, so that the partition plate 25, the drive motor 71, or the eccentric cam 65 that transmits the driving force of the drive motor 71 to the partition plate 25, etc. Since the stress applied to the transmission mechanism can be reduced, it is possible to protect the skewer alignment portion 5.

Further, since the partition plate 25 is configured by fixing only the base end portion in the extending direction of the elastic plate 63 to the metal plate 62, the gun skewer 100 is connected to the partition plate 25 and the bottom surface 26 of the skewer insertion portion 21. Even if the force sandwiched between them is excessively strong, it is possible to prevent this force from inhibiting the swing of the partition plate 25 by the drive motor 71.
Specifically, when the partition plate 25 is sandwiched between the partition plate 25 and the bottom surface 26 of the skewer insertion portion 21 by moving from the allowable position P2 to the restriction position P1, FIG. ), The elastic plate 63 is elastically deformed in the middle in the extending direction, so that only the metal plate 62 is allowed from the restricting position P1 while the tip portion of the elastic plate 63 remains on the restricting position P1 side. It becomes possible to move toward the position P2. Therefore, it is possible to prevent stress from being applied to the drive motor 71 and the transmission mechanism for swinging the partition plate 25 without hindering the swing of the partition plate 25. Therefore, the skewer alignment portion 5 can be further protected.
Further, in the state where the midway portion of the elastic plate 63 in the extending direction is elastically deformed as described above, the elastic deformation of the midway portion of the elastic plate 63 with respect to the tip portion of the elastic plate 63 remaining on the regulation position P1 side. Is applied in the direction from the restriction position P1 side toward the allowable position P2 side. That is, it becomes possible to automatically release the sandwich of the gun skewer 100, and the handling of the skewer aligning unit 5 and the dumpling manufacturing machine 1 is further facilitated.

  Further, the bottom surface 26 of the skewer insertion portion 21 is configured by forming a first inclined surface 26a having a gentler inclination angle than the second inclined surface 26b on the upper end side in the inclination direction of the second inclined surface 26b. It can suppress that the weight of the gun skewer 100 deposited on the one inclined surface 26a is applied to the gun skewer 100 deposited on the second inclined surface 26b. Therefore, the weight of the gun skewer 100 in the skewer insertion portion 21 applied to the partition plate 25 is also reduced, and the driving force for swinging the partition plate 25 can be kept small.

Further, since the base end portion of the aligning and conveying surface 31 of the aligning table 22 includes the upper inclined surface 33, the gun skewer 100 supplied from the skewer loading unit 21 to the aligning table 22 as the partition plate 25 swings is included in the gun skewer 100. A force from the distal end side in the extending direction of the alignment conveyance surface 31 toward the proximal end portion acts by its own weight. For this reason, it is possible to suppress the gun skewer 100 supplied from the skewer loading unit 21 to the alignment table 22 from flowing toward the front end side of the alignment conveyance surface 31 with respect to the alignment conveyance roller 23.
Further, a force from the distal end side in the extending direction of the aligned conveying surface 31 toward the proximal end side also acts on the gun skewer 100 biased by the aligned conveying roller 23 at the proximal end portion of the aligned conveying surface 31. The gun skewer 100 can be aligned with its own weight without a gap at the base end portion of the alignment transport surface 31.

  Further, since the aligning and conveying surface 31 of the aligning table 22 is a mountain-shaped inclined surface, the biasing force of the aligning and conveying roller 23 is applied to the plurality of gun skewers 100 aligned from the lower end to the upper end side of the lower inclined surface 34. Does not act, or the urging force of the alignment transport roller 23 acting on the plurality of gun skewers 100 becomes weak. Therefore, the gun skewer 100 aligned on the aligning / conveying surface 31 is not sandwiched between the aligning / conveying roller 23 and the skewer drum 91 by the urging force of the aligning / conveying roller 23, and the gun aligned to the aligning / conveying surface 31. It is possible to prevent a disorder in the alignment state of the skewer 100.

Further, when the gun skewer 100 slides down toward the lower end side of the downward inclined surface 34, as shown in FIG. 4, the skewer bar portion 100a of the gun skewer 100 comes into surface contact with the alignment conveying surface 31 and the gripping portion 100b. Since the inclined end surface 100 d is in surface contact with the inclined inner side surface 36 b of the insertion groove 36, the rotation of the gun skewer 100 in the plane along the alignment conveying surface 31 is suppressed or prevented. Accordingly, it is possible to reliably match the longitudinal direction of the sliding skewer skewer 100 at the lower end of the downward inclined surface 34 with the width direction of the downward inclined surface 34.
For example, as shown in FIG. 9A, when the inclined end surface 100d of the grip portion 100b is not in surface contact with the inner side surface 36d of the insertion groove 36, or the inner side surface 36d of the insertion groove 36 is aligned and transported surface 31. 9B, as shown in FIG. 9B, the gun skewer 100 rotates around the boundary between the skewer bar portion 100a and the grip portion 100b in the plane along the alignment conveying surface 31. Therefore, the longitudinal direction of the gun skewer 100 is inclined with respect to the longitudinal direction of the alignment conveyance surface 31. As a result, the direction of the gun skewer 100 may become oblique at the lower end of the downward inclined surface 34. Note that the rotation of the gun skewer 100 described above is caused by the fact that the center of gravity of the gun skewer 100 is shifted to the grip portion 100b side from the intermediate position in the longitudinal direction of the gun skewer 100.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the spirit of the present invention.
For example, the moving direction of the partition plate 25 from the allowable position P2 to the restricting position P1 is set to a direction from the upper end side to the lower end side in the inclination direction of the second inclined surface 26b so as to be opposite to the above embodiment. Also good. In this case, it is preferable that the stacking order of the elastic plate 63 and the metal plate 62 constituting the partition plate 25 is also reversed from the above embodiment. In other words, the elastic plate 63 and the metal plate 62 may be stacked in order from at least the allowable position P2 side to the restricting position P1 side.

In addition, the partition plate 25 is configured by laminating the elastic plate 63 and the metal plate 62. However, for example, the entire partition plate 25 may be configured by the metal plate 62 or opposed to the second inclined surface 26b. Only the front end of the partition plate 25 in the extending direction may be formed of an elastic member such as rubber.
Further, the partition plate 25 is attached to the alignment table 22 and the skewer insertion portion 21 so as to be swingable. However, at least a restriction position for restricting the movement of the gun skewer 100 from the skewer insertion portion 21 side to the alignment table 22. It is only necessary to be able to move between P1 and the allowable position P2 that allows the movement of the steel skewer 100. That is, the partition plate 25 can be reciprocated up and down, for example, above the bottom surface 26 of the skewer insertion portion 21 so that the gap between the leading end portion in the extending direction and the bottom surface 26 of the skewer insertion portion 21 changes. Also good.

Further, the inclined end surface 100d of the grip portion 100b and the inclined inner side surface 36b of the insertion groove 36 of the alignment table 22 are curved surfaces corresponding to each other, but are not limited to this, for example, as shown in FIG. It may be a flat surface.
Furthermore, the inclined end surface 100d of the grip portion 100b and the corresponding inclined inner side surface 36b of the insertion groove 36 of the alignment table 22 are not limited to being formed on the entire end surface of the grip portion 100b and the inner surface of the insertion groove 36. Instead, for example, as shown in FIGS. 12A and 12B, it may be formed only on a part of the end surface of the grip portion 100 b and the inner surface of the insertion groove 36.

In addition, the alignment transport surface 31 is configured by the upper inclined surface 33 and the lower inclined surface 34, but may be configured by only the upper inclined surface 33, for example, or may be a surface parallel to the horizontal plane without being inclined. There may be.
Further, the sweep-back roller 24 of the above embodiment is a brush roller in which fibers made of resin or the like are planted on the outer peripheral surface of the roller body 51 so that the skewer is not damaged. It is sufficient that the shape is formed so as to be able to sweep back to at least the base end side of the alignment transport surface 31. Therefore, for example, the sweep back roller 24 may be formed by forming a protrusion having high rigidity on the outer peripheral surface of the roller main body 51 in the same manner as the biasing protrusion 42 of the alignment transport roller 23, or only the roller main body 51, for example. May be configured.

Moreover, in the dumpling production machine 1 of the above embodiment, the dumpling dough is divided and formed by both the pair of dough rolls 11 and 11 and the forming rolls 4A and 4B. May be formed into a plate shape extending below the dough roll 11, and the dumpling dough may be divided and formed into ball units only by the pair of forming rolls 4A and 4B. That is, a dumpling forming part that splits and forms dumpling dough into dumplings for skewers may be configured only by the forming rolls 4A and 4B.
Furthermore, the dumpling of the skewer dumpling manufactured by the dumpling manufacturing machine 1 is not limited to a spherical shape, and may be of an arbitrary shape such as a rod shape. In this case, for example, the specifications of the forming rolls 4A and 4B, the rounded forming portion 8 and the like constituting the dumpling production machine 1 may be appropriately changed according to the shape of the dumpling.

  And the skewer alignment apparatus (skewer alignment part) concerning this invention and the dumpling manufacturing machine provided with this are applicable not only to what is applied to the gun skewer 100 but at least to the skewer formed in a rod shape. For example, it can be applied to a round skewer. When the skewer is a simple bar like a round skewer, the insertion grooves 27 and 36 for the gripping portion 100b formed on the bottom surface 26 of the skewer insertion portion 21 and the alignment conveyance surface 31 of the alignment table 22 are unnecessary.
