BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a muscular tendon excision machine for bird gizzards for excising muscular tendons of gizzard liver (gizzard) of birds.

[0002]

2. Description of the Related Art Conventionally, an operator manually cuts muscle tendons on the upper and lower surfaces of a sand liver in order to skewer the liver of the bird into a yakitori, so that a worker manually uses a cutter or the like. Although I was doing it, it was a difficult and time-consuming task because the muscle tendon was thin and strong.

The present invention provides a muscular tendon resection machine for bird's gizzard liver that solves the above drawbacks.

Reference numeral a ₁ indicates a thin muscle tendon portion in the center of the gizzard halves a. 3 shows a state in which the sand liver half a is held between the sprocket 5 and the lower surface of the feed chain 4 and the left and right ends a ₂ of the muscular tendon a ₁ are cut by the muscular tendon cutting blade 8. FIG. 4 is a schematic explanatory view showing a state in which the sand liver half a is cut and separated into two left and right cut sand liver a ₃ and muscle tendon a ₁ .

An embodiment of the present invention will be described with reference to FIGS.

An angled guide strip 3 is fixed to a table 2 connected to the machine body 1 with its apex facing upward.

An introduction sprocket 12 and an idle sprocket 13 are arranged on the upper part of the machine body 1, a lead-out sprocket 14 is provided on the lower part of the machine body 1, and a feed chain 4 is wound around the sprockets 12, 13, 14 and the feed chain 4 is wound. The feed sprocket 5 for driving the No. 4 is provided between the introduction sprocket 12 and the lead-out sprocket 15, and the mounting position of the introduction sprocket 12 and the feed sprocket 5 is introduced by the rotation of the feed sprocket 5 by the feed chain 4 wound around the introduction sprocket 12. The tension side line of the feed chain 4 when pulled out from the lower end of the sprocket 12 is provided so as to be substantially aligned with the horizontal extension line of the guide strip 3, and the mounting position of the lead-out sprocket 14 is engaged with the feed sprocket 5 The chain 4 is wound around the feed sprocket 5 at a winding angle of approximately 90 ° or more, and the derived sprocket 14 A tension device (not shown) for tensioning the feed chain 4 on the lead-out sprocket 14 is provided at a position where the feed chain 4 is wound around. An elastic roller 15 is provided on the upper side of the feed chain 4 slightly to the right of the feed sprocket 5 so as to abut the roller of the feed chain 4 and press the feed chain 4 into mesh with the sprocket teeth of the feed sprocket 5.

A driven sprocket 20 is fixedly attached to a rotary shaft 19 for rotating the feed sprocket 5, and a drive sprocket 18 is attached to an output shaft 17 of an electric motor 16 installed inside the machine body 1.
Fit this drive sprocket 18, driven sprocket
Wind the drive chain 21 between 20.

A sprocket for feeding a muscle tendon cutting blade 8 for cutting the left and right ends a ₂ of the muscular tendon a ₁ of the sand liver half a in a diagonally downward right direction from the vicinity of the contact portion of the feed chain 4 of the elastic roller 15. 5 are installed in close proximity to each other on both sides of the muscle tendon cutting blade 8 and diagonally downward to the left from the lower part of the muscle tendon cutting blade 8 to collect the cut sand liver a ₃
The guide guides 22 to be guided to 0 are provided oppositely on both sides of the feed sprocket 5, and the paying rods 23 are fixed to both sides of the feed sprocket 5 slightly apart from the center of the feed sprocket 5, and the paying rods 23 are used to guide the guides. 22 Part of the cut sand liver a ₃
Are collected in the box-shaped collecting section 9.

Further, a channel-shaped chute 24 having an opening on the right side is provided in the lower portion of the feed sprocket 5, and the introduction sprocket 5 is provided on both sides of the sprocket teeth slightly below the separation portion between the feed sprocket 5 and the feed chain 4. And the tendon a attached to either one of the feed chain 4
_A removing piece (25) for projecting ₁ into the chute (24) is provided to project, and the lower end of this removing piece (25) is fixed to both side surfaces of the shoe (24).

Since the embodiment is constructed as described above, the operator puts the gizzard half a on the guide strip 3 and moves the gizzard half a on the guide strip 3 by hand in the direction of the cutting portion. When pushed,
The gizzard halves a are introduced into the holding and introducing section 6 on the lower surface of the feed chain 4 wound around the sprocket 12, and the rotation of the sprocket 5 causes the thin muscular tendon a at the center of the gizzard halves a to be inserted.
₁ is moved with the rotation of the feed sprocket 5 while being held between the lower surface of the feed chain 4 and the sprocket teeth of the feed sprocket 5, and is pressed onto the sprocket teeth by the elastic roller 15. Then, the sand liver half a is cut by the muscle tendon cutting blades 8 on both sides of the feed sprocket 5 to cut the left and right end portions a ₂ of the muscle tendon portion a ₁ , and the cut left and right two cut sand liver a ₃ are self-weighted. Then, it is collected on the collecting section 9 after being retained on the lead-out guide 12.

At this time, since the cut sand liver a ₃ sometimes remains adhering to the lead-out guide 22, the attached cut sand liver a ₃ can be wiped off onto the lead-out guide 22 by the paying rod 23 rotating together with the feed sprocket 5. Then, drop it and store it in the collection section.

Further, between the feed sprocket 5 and the lead-out sprocket 14, either the feed sprocket 5 or the feed chain 4 is attached to _one of them, the muscle tendon portion a ₁ is pushed down by the removing piece 25, and is passed through the chute 24 to the box. It collects in the shape of a collection part.

In the figure, reference numerals 26 and 27 are derived sprockets 1.
4. A safety bar for preventing the feed chain 4 from deviating from the idle sprocket 13, 28 is a safety cover, and 29 is a vertically adjustable mounting leg.

[0019]

Since the present invention is configured as described above, the operator puts the gizzard halves on the chevron-shaped guide strips and moves the sand hepatic halves on the guide strips by hand in the direction of the cutting portion. When pushed,
The gland liver half is moved while being pinched by the feed chain and feed roller, the muscle tendon of the gland liver half is cut by the cutting blade above the muscle tendon, and then the cut gizzard liver and muscle tendon are automatically separated. Since it can be collected in the respective collecting parts, it is a practical and excellent bird's gland liver muscle tendon cutting machine with significantly improved workability compared to conventional manual work.
