  Examples of the transport conveyor include an endless transport chain and a transport belt that are wound around a drive sprocket and a driven sprocket. Particularly, a transport chain with an attachment can be preferably exemplified. Although the skewer holder is rotatable in cooperation with the skewer holder, it is preferable to fix the attachment member of the skewer holder having a structure capable of regulating the position in the transport direction and the direction orthogonal to the transport direction. As such a holding member, for example, a rectangular block-shaped holding block having a semi-cylindrical or inverted U-shaped cutout at the lower end can be attached to a transport chain with an attachment via the attachment. The skewer holder can be rotatably held. The holding block is preferably fixed to the two pieces of the chain at a ratio of one. With this holding block, the skewer holder can be held so as to be conveyed while being reversed at the skewer reversing station. The pitch of the skewer holder to be conveyed is the same as the pitch of the holding block, but it is preferable to set the interval twice as long as the chain pitch of the chain (a range of 38.1 mm).

Therefore, the skewer discharge rod may be retracted to the center hole side adjacent to one end (back) of the flat hole, and is advanced slightly beyond the other end (insertion port). There may be. In addition, a medium-diameter cylindrical body can be formed between the large-diameter cylindrical body and the small-diameter cylindrical body.

  The large-diameter cylindrical body is not particularly limited as long as it can stably hold or support the skewer, but is preferably composed of two parts so as to facilitate molding. In the case of two parts, it is preferable to bias the flat holes in the direction of narrowing each other with a spring, an annular spring ring or the like. For example, the large-diameter cylindrical concave body and the large-diameter cylindrical convex body, the flat hole is formed from the concave surface portion of the large-diameter cylindrical concave body and the convex surface portion of the large-diameter cylindrical convex body, the large-diameter cylinder It is preferable that the concave concave body and the large-diameter cylindrical convex convex body are urged by a spring screw, an annular spring ring, or the like in the direction of narrowing the flat holes. Also, it is possible to form the insertion hole of the flat hole as a funnel-shaped opening that becomes smaller toward the back, and the tapered surface serves as an insertion guide for the skewer. It is preferable in terms of improvement. Moreover, the material of the large-diameter cylindrical body is preferably a heat-resistant plastic because it is directly exposed to a heating source such as charcoal fire.

  The small-diameter cylindrical body is connected to the large-diameter cylindrical body, communicates with the flat hole in the large-diameter cylindrical body, and one end of the skewer discharge rod advances and retracts at least from the end to the end of the flat hole. As long as it has a central hole through which it is inserted, there is no particular limitation, and such a small-diameter cylindrical body is usually made of a metal pipe that is easy to process because it is not directly exposed to a heating source such as charcoal fire. When the outer diameter of the large diameter cylindrical body is 3 to 4 cm, the outer diameter of the small diameter cylindrical body is preferably 8 to 15 mm.

  The skewering apparatus of the present invention includes skewer reversing means. As the skewer reversing means, a plurality of, preferably 3-7, more preferably five racks for skewer reversal arranged in parallel with the traveling direction of the transport conveyor in the vicinity of the circulation path of the transport conveyor of the skewer heating station, In cooperation with the skewer reversing rack, the skewer holder, which is a connecting body of the large-diameter cylindrical body and the small-diameter cylindrical body, is inverted and inserted into the small-diameter cylindrical body opposite to the large-diameter cylindrical body. The skewer reversing pinion gear is provided. When the skewer holder into which the skewer is inserted is moved to the skewer reversing station by sliding and moving on the horizontal plane, the skewer reversing pinion gear meshes with the rack teeth, and the skewer reversing pinion gear is gradually reversed to reverse the skewer. The skewer holder to which the pinion gear is fixed is turned over. For example, when the skewer reversing racks are arranged at appropriate intervals such as at equal intervals (five skewer reversing stations) at five locations, the skewers can be reversed five times, and can be fired on the front and back three times. The number of teeth of the skewer reversing pinion gear is preferably an even number of about 12 to 20, for example, when the number of teeth is 16, the number of teeth of the rack is 6. When the skewer holder has the sliding guide member, the guide rail corresponding to the sliding guide member is configured not to slide at the skewer reversing station so as not to prevent the skewer holder from being reversed. The skewer reversing pinion gear may be formed integrally with the sliding guide member.

  The skewering apparatus of the present invention includes skewer discharging means for automatically dropping off the skewer inserted in the skewer holder. Such skewer discharge means includes a skewer discharge guide plate provided at the end portion of the skewer conveyance path, and the insertion through the center hole, in which the insertion skewer is detached from the skewer holder in cooperation with the skewer discharge guide plate. One end of the flat hole is constituted by a skewer discharge rod that advances and retreats at least from the end to the end of the flat hole. An example of the skewer discharge guide plate is a guide plate that is arranged so that the front of the skewer discharge rod is closer to the transfer conveyor and the guide rail toward the transfer direction, and one end of the skewer discharge rod is in contact with the skewer discharge guide plate. . Examples of the skewer discharge rod include a plate-like rod having a central portion formed as a wide portion and a columnar rod having a central portion formed as an enlarged portion, and both ends of the wide portion and the enlarged portion. Is regulated in the longitudinal direction by the stopper action of the reduced diameter portion formed in the center hole of the small diameter cylindrical body, and one end of the rod advances and retreats from the end (back) of the flat hole to the end (insertion port). What is comprised is preferably. In the skewer insertion station, when the flat skewer base end is inserted into the flat hole of the skewer holder, one end of the rod retracts to the end (back) of the flat hole and the other end retracts outside the center hole. However, there is no excessive withdrawal due to the stopper action. Then, when the skewer holder is conveyed to the skewer discharge station, the rod gradually advances while the other end of the rod is in contact with the skewer discharge guide plate, and the one end of the rod is the end of the flat hole ( It advances to the insertion port) (the skewer leaves), but it does not advance too much due to the stopper action. As a result, the skewer automatically drops from the skewer holder. Note that the rod can be biased in the retracting direction by a spring or the like.

  The skewer holder of the present invention is preferably provided with a guide member. As such a guide member, a member that can stably and smoothly convey the skewer holder in cooperation with the guide rail is preferable, and one guide rail may be used, but two guide rails are preferable. If the guide rails are a pair of upper and lower guide rails facing each other in parallel, except for the reversing station, in order to carry the skewer stably, the guide member slides between the upper and lower guide rails. Preferably, the sliding guide member has two sliding surfaces that are parallel to each other. Also, in order to smoothly carry the skewer, the guide member is inserted into the large-diameter cylindrical body side of the small-diameter cylindrical body, and supports the small-diameter cylindrical body and rolls on the guide rail. It can also be a guide member. When there are two guide rails, it is preferable that one of them is for a sliding guide member having two sliding surfaces, and the other is a rolling guide member. For example, when the outer guide rail and a pair of upper and lower inner guide rails arranged in parallel to face each other are arranged as two guide rails, the rolling guide member and the sliding guide member as guide members Is preferably used. In this case, a small-diameter cylindrical body portion in which the rolling guide member and the sliding guide member are not inserted and fixed can be used as the receiving portion of the holding block.

  The skewering apparatus of the present invention is used in the method for manufacturing a frozen grilled skewer of the present invention. When the empty (not inserted skewer) skewer holder held by the conveyor is continuously conveyed to the skewer insertion station by the rotation of the conveyor chain, the skewer is manually inserted. Since the skewering station does not have a heating source such as charcoal fire, the operator's hand is cut off from the heating source. The skewer holder with the skewer inserted approximately horizontally is then transported to a skewer heating station equipped with a heating source such as charcoal fire, and one side of the skewer is transported while being fired until the first skewer inversion station provided in the skewer heating station When transported, the skewer is inverted, and the other surface of the skewer is transported while being baked. When the skewer is conveyed to the next skewer inversion station, the skewer is inverted and one side of the skewer is fired (second time). Thus, when both sides of the skewer are repeatedly fired a plurality of times, preferably 2 to 5 times, the skewer is dropped at the skewer discharge station, and frozen after recovery and cooling.
