Description

  The present invention relates to a fruit seeding device that reduces the amount of flesh adhering to the seeds to be extracted when extracting fruit seeds such as plums, apricots, and peaches, thereby improving the residual ratio of the pulp after seeding. And a seed removal method.

  It is common to pre-seeded salted plums and candy processed into confectionery or canned fruits that are attached to sold lunch boxes. In the food processing factory, etc., it was carried out manually by workers using fingers, chopsticks or forks. This seed removal work must be scraped from the seed so that the pulp attached to the seed can be recovered as much as possible. The handling quantity is also large. Therefore, in recent years, various seeding devices that mechanize fruit seeding work have been proposed.

  The seed removal device includes a placement plate having a fruit placement surface formed on a flat single surface with silicone rubber, and the fruit placement surface has an outer diameter around the minor axis of the seed to be extracted from the fruit. A circular through-hole with a small inner peripheral dimension is formed, and a thrust bar that is vertically driven so as to be able to pass through the circular through-hole is disposed above the mounting plate, and projects toward the circular through-hole of the mounting plate. By driving the rod, the seed placed on the mounting plate (in this case plum dried) is inserted into the circular penetrating penetrary by pushing the seed and pressing the seed. Is known (see, for example, Patent Document 1).

  As another seed removal device, a number of seed removal rods arranged in parallel at intervals are directly below the seed removal plate that can be vertically moved, and the fruit (in this case as well) has the same interval as the seed removal rod. An upper plate having a large number of accommodation holes that can individually accommodate (plum pickled), and a seed hole that allows the fruit seeds to pass through the center of the accommodation hole with a smaller elasticity than the fruit seeds. The pallet is formed by sandwiching the elastic plate and the lower plate having the discharge hole at the position corresponding to the accommodation hole of the upper plate, and the seeding machine is lowered to lower the seeds. What is performed all at once has been proposed (see, for example, Patent Document 2).

  Further, as another seed removal device, a cylindrical receiver that has a taber-shaped inner peripheral surface that is reduced in diameter downward and supports fruits on the taber-shaped inner peripheral surface, and is disposed at a position below the cylindrical receiver. And a rubber plate having a plurality of slits extending radially from the center of the plate in a radial direction, and a rod body that is vertically driven so as to be able to pass through the inside of the cylindrical receiver, and is a taber shape of the cylindrical receiver. There is also known a structure in which a rod is passed downward through a fruit placed on the inner peripheral surface and a seed is taken out, and this seed is further passed through a slit of a rubber plate (for example, see Patent Document 3). ).

However, in any of the above-described seeding devices, the seeds are pulped by lowering the seeding bar and penetrating downward through the fruit pulp to directly press the seeds with the bar. Since the seeds are pushed out at a stroke until they fall down and fall down, the seeds are extracted with a lot of attached flesh, so the loss of pulp is large and the residual rate of pulp after seeding is low . Therefore, in the above-described seed removal device, in order to improve the remaining rate of the pulp, a through hole having an inner diameter smaller than the outer diameter of the seed is formed in the elastic plate member, and the seed pushes the through hole. By passing through while being deformed so as to expand, the seed is squeezed by the inner peripheral wall of the through hole, and the pulp attached to the extracted seed is peeled off from the seed. In this case, since the outer diameter and posture of the seed of the fruit of the workpiece are not uniform, if the inner diameter of the through hole is too small relative to the outer diameter of the seed, the seed cannot be extracted smoothly, and conversely When the inner diameter of the through hole is too large with respect to the outer diameter of the seed, peeling of the flesh adhering to the seed becomes insufficient. In addition, in any seeding device, the rod-like body penetrates the inside of the fruit pulp at once and completely, so that the pulp after seeding is greatly deformed with the formation of the through-hole of the rod-like body. It will be deformed and subsequent processing becomes troublesome.

  Further, in any conventional seeding device, no consideration is given to the existence position in the pulp of the seed before seeding in the fruit to be processed and whether the orientation is horizontal or vertical. For this reason, if the seeds are present in a biased position near the skin that is off the center of the pulp, or if the seeds are present in a vertical orientation in which the major axis direction extends vertically, There is a possibility that the rod may not come into contact with a position where the rod can be surely pressed down against the seed, and the seed may escape from the rod to the side and be pulled out. Further, in each of the conventional seeding devices, the tip portion of the seed and the rod-like body that presses down the seed so as to expand a through-hole formed in the elastic plate-like member with an inner diameter smaller than the outer diameter of the seed. Since it passes through while deforming, the tip of the rod-shaped body is moved to return to the home position after the tip of the rod-shaped body has passed through the through-hole and dropped, and the tip of the rod-shaped body is The flesh adhering to the tip of the rod-shaped body when squeezing with the restoring force acting on the inner peripheral surface of the through hole due to the expansion deformation of the through hole penetrates the inside of the fruit on the inner peripheral surface of the through hole. It is peeled off and separated from the fruit after seed removal. This also further reduces the residual rate of pulp after seed removal.

  The present invention has been made in view of the above problems, and by reducing the amount of pulp attached to the seed to be extracted and reducing the loss of the pulp, it is possible to improve the residual ratio of the pulp after seeding. An object of the present invention is to provide a fruit seeding device and seeding method.

  In order to achieve the above object, the fruit seeding device of the invention according to claim 1 has a tapered inner peripheral surface that is reduced in diameter downward and a hole shape having a diameter through which fruit seeds can pass at the lower end of the inner peripheral surface. A fruit holding hole portion having a seed passage hole opened in the pallet, a pallet that is sequentially conveyed to each step while holding the fruit to be processed inside the fruit holding hole portion, and subjected to pressure In some cases, a seeding hole formed in a plate shape with a material that can be elastically deformed and having a smaller diameter than the seed passage hole is concentrically opposed below the seed passage hole. A pulp stripping plate fixed to the lower surface of the pallet, and when the pallet is transported to the seeding process, it is lowered into the pulp of the fruit held on the pallet and pressed inside the pulp while pressing the seed. The seed that progresses downward and is pressed is the pulp A seeding rod that is driven up and down by an up-and-down stroke with the lowest point when passing through the seeding hole of the peeling plate through the pulp of the seeding hole, and the seeding rod And a cutting blade for cutting the pulp existing between the suspended seed and the pulp stripping plate and separating the seed from the pulp.

A fruit seeding device according to a second aspect of the present invention is the fruit seeding device according to claim 1, wherein the fruit seeding device is lowered when the pallet is transported to a fruit shaping step provided in a preceding stage of the seeding step. The fruit held in the pallet is held by the upwardly concave pressing surface formed on the lower end surface of the rod-shaped body having a diameter corresponding to the upper end opening of the fruit holding hole in the pallet. It is characterized by comprising a fruit shaping member that is pressed onto the inner circumferential surface of the fruit to shape the shape of the fruit so that the seed is located in the center of the pulp.

  A fruit seeding device according to a third aspect of the present invention is the fruit seeding device according to claim 1 or 2, wherein when the processing in the seeding step is finished, the fruit seeding device is raised. A pulp collecting member that is inserted through the seeding hole from below and pushes the pulp that adheres to the periphery of the hole below the seeding hole into the fruit holding hole of the pallet. Yes.

  According to a fourth aspect of the fruit seeding method of the present invention, when the pallet holding the fruit to be processed is transported to the seeding process inside the fruit holding hole, the seeding bar is lowered, Press the seed in the pulp with the seeding rod that has entered the pulp, and after the seed passes through the seed passage hole that opens at the lower end of the fruit holding hole, it can be elastically deformed fixed to the lower surface of the pallet By stopping the descending of the seeding rod when the seed has passed through the seeding hole formed in a hole shape having a smaller diameter than the seed passage hole in the plate-like pulp stripping plate made of a raw material The first processing step of bringing the seed into a suspended state on the pulp stripping plate through the pulp existing in the seeding hole after passing through the seeding hole; and After finishing the processing, operate the cutting blade, through the pulp in the seeding hole It is characterized by and a second processing step of separating the seeds from the pulp the pulp present between the lower state species as the pulp peeling plate and cut with the cutting blade.

  According to the fruit seeding device according to claim 1, when the seed has finished passing through the seeding hole, the seeding rod that enters the fruit pulp and pushes down the seed while moving downward in the pulp is lowered. Since the seeds pass through the seeding holes while deforming so as to expand the seeding holes of the pulp stripping plate made of an elastically deformable material, the seeds remove the pulp existing in the seeding holes. In this state, the flesh existing between the seed and the flesh stripping plate is cut by the operation of the cutting blade to separate the seed from the flesh. Therefore, in this seed removal device, as in the conventional device, the seed is pushed directly with the rod-shaped body and pushed out at once with the rod-shaped body until the seed is separated downward from the pulp and dropped, so there are many seeds. Unlike the one that is pulled out with the flesh attached, the seeding rod just before the seeding rod penetrates the skin and penetrates the inside of the pulp, that is, immediately before the tip of the seeding rod passes through the seeding hole. The seeds are squeezed when passing through the seeding hole while deforming the seeding hole of the flesh stripping plate so as to expand the seeding hole. The flesh adhering to itself is peeled off sufficiently. As a result, in this seed removal device, the amount of pulp attached to the seed to be extracted can be reduced to reduce the loss of the pulp, and the residual ratio of the pulp after seed removal can be improved.

  According to the fruit seeding device according to claim 2, prior to the seeding process, the fruit held on the pallet is held by the concave pressing surface formed upward on the lower end surface of the fruit shaping member. By pressing on the inner peripheral surface of the hole, the shape of the fruit is shaped so that the seed is located in the center of the pulp as much as possible, so the descending seeding rod can be pressed against the seed Since it can be surely brought into contact with the position, it does not occur that the seed escapes to the side from the rod-like body where the seed descends as in the conventional device, and the removal failure occurs. Thereby, in this seed removal apparatus, the yield of the pulp remaining after seed removal is improved.

According to the fruit seeding device according to claim 3, the pulp passing through the seeding hole while adhering to the seed and adhering to the hole periphery below the seeding hole is inserted into the seeding hole from below. The pulp recovery member that is raised while being pushed back into the fruit holding hole of the pallet further improves the residual rate of the pulp after seed removal. In addition, since the seeding rod stops descending when the seed has passed through the seeding hole, the portion of the seeding rod where the pulp has adhered is not inserted into the seeding hole, so it adheres to the seeding rod. In this respect, the remaining rate of the pulp after seed removal is further improved.

  According to the fruit seeding method according to claim 4, since the seed has stopped descending when the seeds have passed through the seeding hole, the seeds are provided with a seeding hole on the pulp stripping plate. As the result of squeezing when passing through the seeding hole while deforming so as to spread, the flesh adhering to itself is sufficiently peeled off, reducing the amount of flesh adhering to the seed to be extracted and reducing the pulp loss It is possible to reduce the residual rate of the pulp after seed removal.

Further, as shown in FIG. 2, each seed pallet 8 of the pallet unit body 20 in the seed-extracted pulp dispensing mechanism 6 is in a lateral orientation in which the upper end opening of the pallet unit body 20 faces the direction of the seed-extracted pulp transport conveyor 7. In addition, five payout bars 24 that move forward toward each pallet 8 and simultaneously pay the seeded pulp in each pallet 8 onto the seeded pulp transporting conveyor 7 are arranged.

  In FIG. 3 which shows the enlarged front view of the fruit shaping mechanism part 3 in the above-mentioned seed removal apparatus, as for this fruit shaping mechanism part 3, the support arm 28 is a side from the upper end part vicinity of the support | pillar 27 standingly arranged on the base 19. The pressing cylinder 29 is attached to the support arm 28 in a suspended state. The fruit shaping member 9 attached to the tip of the piston rod 29a of the holding cylinder 29 has a smooth concave shape with the central portion facing upward at the lower end surface of a rod-like body having a diameter slightly smaller than the upper end opening of the pallet 8. A holding surface 9a having a shape is formed. Further, a receiving member 31 that is moved up and down by the operation of the receiving cylinder 30 is provided at a position facing the fruit shaping member 9 in the lower part with the pallet 8 and the pallet transport conveyor 18 interposed therebetween. The receiving member 31 has a receiving surface 31a having a smooth concave shape with a central portion facing downward on the upper end surface of a rod-like body having a diameter slightly larger than a seed passage hole 83 to be described later that opens at the lower end of the pallet 8. Is formed.

  On the other hand, the pallet 8 connected to the pallet unit body 20 in an array of five has a diameter that allows the seed T of the fruit A to pass through in a horizontal posture at a tapered inner peripheral surface 82 that is reduced in diameter downward and at a lower end of the inner peripheral surface 82. A fruit holding hole 81 having a seed passage hole 83 opened in the shape of the hole is formed, and the pallet conveyor 18 is intermittently held while holding the fruit A to be processed in the fruit holding hole 81. It is designed to be sequentially transferred to each process by simple forwarding. The bottom surface of the pallet 8 is formed in a flat plate shape by a material such as rubber that can be elastically deformed when pressurized, and a flesh stripping plate 32 with a slit or the like is fixed by means such as sticking. ing. The pulp stripping plate 32 is formed with a hole-shaped seeding hole 32a having a diameter R2 smaller than the diameter R1 of the seed passage hole 83 of the pallet 8. The pulp stripping plate 32 has its own seeding hole 32a. Is fixed to the lower surface of the pallet 8 in a concentrically opposed manner below the seed passage hole 83.

  In FIG. 4 which shows the enlarged front view of the seeding mechanism part 4 in the above-mentioned seeding device, this seeding mechanism part 4 has the support arm 34 side from the vicinity of the upper end part of the column 33 erected on the base 19. The seeding cylinder 37 is attached to the support arm 34 in a suspended state. The seeding rod 10 attached to the tip of the piston rod 37 a of the seeding cylinder 37 is lowered by the operation of the seeding cylinder 37 when the pallet 8 is conveyed to the seeding mechanism 4, and the pallet 8. The fruit A held in the fruit holding hole 81 enters the pulp of the fruit A and proceeds downward in the pulp while pressing the seed T, and is driven up and down by a predetermined vertical stroke set as described later.

Further, a guide cylinder 38 is supported on the side surface portion of the support column 33 so as to face the vertical direction, and a mounting plate extending horizontally toward the side is provided at the tip of the piston rod 38a of the guide cylinder 38. A guide part 41 is arranged at a position directly above the pallet 8 conveyed to the seeding process via 40. The guide member 41 has an insertion hole 41a of the seed removal rod 10, an inclined surface 41b formed at an inclination angle matching the tapered inner peripheral surface 82 of the pallet 8 on the lower end outer peripheral surface, and a central portion of the lower end surface upward. A relief recess 41c formed in a concave shape, and a pressing surface 41d formed in a horizontal plane between the relief recess 41c and the inclined surface 41b.

  Two cutting blades 42 and 43 are located at the lower vicinity of the pulp stripping plate 32 fixed to the lower end surface of the pallet 8 conveyed to the seeding mechanism 4, and the seeds of the pulp stripping plate 32 when not operating. They are arranged so as to oppose each other at both sides of the punched hole 32a. Each of the cutting blades 42 and 43 is fixed to an upper end portion extending in the vertical direction of the support plate 48 so as to be opposed to each other in the horizontal direction, and the lower end portion of the support plate 48 is a plurality of pistons of the cutting cylinder 44. It is attached to a connecting plate 47 that connects the rods 44a to each other. Both the cutting blades 42 and 43 are horizontally moved in directions close to each other when the both cutting cylinders 44 are operated so as to discharge the piston rod 44a. Further, the pulp stripping plate 32 and the cutting blades 42 and 43 fixed to the lower end surface of the pallet 8 conveyed to the seed removal mechanism unit 4 are raised by the operation of the recovery cylinder 49 to the pulp. A rod-like pulp collecting member 50 that is inserted from below into the seeding hole 32a of the stripping plate 32 is disposed.

  Next, the operation of the seed removal device will be described in detail with reference to FIGS. A large number of fruits A to be seeded are introduced into the left part of the figure in the fruit supply mechanism 1 of FIGS. 1 and 2, and then transferred to the right by the operation of the vibration feeder 12. When the fruit feed mechanism unit 1 is arranged in a line in the transport groove 14 and reaches the end of the fruit supply mechanism unit 1, one piece is inserted into each pallet 8 of the pallet unit body 20 by the single feed mechanism unit 2.

  As shown in FIG. 5 (a), the fruit A inserted into the fruit holding hole 81 of the pallet 8 is placed in the fruit shaping process in a state of being supported in contact with the tapered inner peripheral surface 82. It is conveyed to the mechanism unit 3. At this time, the fruit (in this embodiment, plum, pickled plum or pickled plum) is merely supported in contact with the tapered inner peripheral surface 82, so that the seed T is in the vertical orientation and in the vicinity of the skin in the pulp. May exist at a biased position. As shown in FIG. 5 (b), when the fruit shaping mechanism 3 is operated in the above state, the fruit shaping member 9 descends and enters the fruit holding hole 81 of the pallet 8, and the receiving member 31. Rises and contacts the pulp stripping plate 32. At this time, the fruit shaping member 9 crushes the fruit A while pressing the fruit A against the tapered inner peripheral surface 82 of the fruit holding hole 81, so that the seed T present in the biased position near the fruit skin is crushed. While the pulp is being deformed, it is pushed by the center part of the pulp, and the pulp enters the recessed part at the center part of the pressing surface 9a that is concave toward the top of the fruit shaping member 9 so that the pulp enters the recess. In many cases, the vertical posture type T is changed to a horizontal posture when the shape is deformed. When the pulp shaping process is completed, the fruit shaping member 9 and the receiving member 31 are returned to the original positions shown in FIG. 5A, and the pallet 8 is conveyed toward the seeding mechanism 4 in the next step.

As shown in FIG. 6A, the pallet 8 conveyed from the fruit shaping mechanism 3 to the seeding mechanism 4 is positioned and stopped just below the seeding rod 10 of the seeding mechanism 4. Subsequently, as shown in FIG. 6B, the seeding mechanism 4 is operated, and the guide member 41 is lowered by driving the guide cylinder 38 and enters the fruit holding hole 81 of the pallet 8 to guide the guide. When the inclined surface 41b of the member 41 is fitted into the tapered inner peripheral surface 82 of the pallet 8 having the same inclination angle, the lowering of the guide member 41 is stopped. Next, the seed removal rod 10 inserted through the insertion hole 41a of the guide member 41 descends and enters the pulp of the fruit A, and advances downward in the pulp while pressing the seed T. At this time, since the seed shaping mechanism unit 3 changes the seed T to a substantially horizontal posture and is positioned at the center of the pulp, the descending seed removal rod 10 is brought into a position where it can be pressed against the seed T. It can be made to contact reliably. Moreover, the seed T does not change its position when the seed removal rod 10 is lowered by the relief recess 41c and the pressing surface 41d of the guide member 41 in which the inclined surface 41b is fitted into the tapered inner peripheral surface 82 of the pallet 8. Since the shape of the pulp is regulated, it does not occur that the seed T escapes laterally from the rod-like body where the seed T descends and is not pulled out unlike the conventional apparatus.

  Further, as shown in FIG. 6 (b), the seed removal rod 10 enters the pulp of the fruit A and advances downward in the pulp while pressing the seed T, as shown in FIG. 6 (b). Is stopped when reaching the position immediately before insertion through the seed removal hole 32a of the pulp stripping plate 32. That is, the seed removal rod 10 is driven up and down with an up and down stroke at which the point when the tip reaches a position immediately before insertion into the seed removal hole 32a is the lowest point. Therefore, after passing through the seeding hole 32a while the seed T is deformed so as to expand the seeding hole 32a of the pulp stripping plate 32 made of an elastically deformable material, the seed T presents the pulp existing in the seeding hole 32a. It will be in a suspended state with respect to the pulp stripping plate 32. In this state, as shown in FIG. 6 (c), the cutting cylinders 44 on both sides are actuated to drive the cutting blades 42, 43 in a direction close to each other. And the flesh stripping plate 32 are cut, and the seed T is separated downward from the pulp.

  Therefore, in the conventional apparatus, since the seed is pressed directly with the rod-like body and the seed is pushed down with the rod-like body until it separates and falls downward from the pulp, the seed is extracted with a lot of pulp attached. In the seed removal mechanism 4 described above, the seed removal is performed immediately before the seed removal rod 10 penetrates the skin and passes through the inside of the pulp, that is, immediately before the tip of the seed removal rod 10 is inserted into the seed removal hole 32a. Since the descent of the rod 10 is stopped, only the seed T is squeezed when passing through the seeding hole 32a while deforming the seed stripping hole 32a of the pulp stripping plate 32 so as to expand. The flesh adhering to the seed T is sufficiently peeled off. As a result, in this seed removal device, the amount of the pulp attached to the seed T to be extracted can be reduced to reduce the loss of the pulp, and the residual rate of the pulp after seed removal can be improved.

  Finally, as shown in FIG. 6D, after the seed removal rod 10 and the guide member 41 are raised and returned to their original positions, the pulp collection member 50 raised by the operation of the collection cylinder 49 is peeled off. The pulp that is inserted from below into the seeding hole 32 a of the collecting plate 32 and adheres to the hole periphery below the seeding hole 32 a is pushed back into the fruit holding hole 81 of the pallet 8. This also improves the remaining rate of the pulp after seed removal.

  The present invention is not limited to the above-described embodiment, and various additions, modifications, or deletions can be made without departing from the scope of the present invention, and such modifications are also included in the scope of the present invention. .
