DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a machine for making a seed oyster master used for oyster cultivation.

[0002]

2. Description of the Related Art The seed oyster master for oyster culture shown in FIG.
A hole is made in a scallop shell 1 (the upper and lower shells are used separately) and passed through a wire 2, and a spacer (vinyl tube) 3 is inserted between the shells so that the shells do not stick to each other. One master usually uses about 70 shells. A number of such masters are suspended at regular intervals on a rope stretched over the sea surface. Eventually, oyster seeds adhere to the master and grow slowly.

Conventionally, such a master is manually made, and a hole is formed in a shell with a pointed hammer, and the hole is alternately passed through a wire with a spacer. However, cultivation of oysters required a large amount of masters, and manual work was inefficient.

[0004]

SUMMARY OF THE INVENTION An object of the present invention is to provide a machine for efficiently making a seed toy master.

[0005]

According to the present invention, there is provided an apparatus for manufacturing a seed master, in which a support shaft is vertically supported on a machine frame. This support shaft repeats a motion of rotating by a certain angle, then lowering by a certain distance and rising again. A plurality of arms are extended radially from the support shaft, and a spindle is fixed downward at a tip of each of the plurality of arms. The spindle is provided with a cone for drilling holes in the shell. Attach a sleeve to the spindle to drop down the shell that the pin has pierced. A spring is provided to bias the sleeve upward against the spindle. A lever mechanism is provided to push down the sleeve when the spindle descends with the arm. Immediately below the spindle, a clamping device for holding the end of the wire upward is provided.

A spacer pipe to be passed through a wire together with a shell,
It is preferable to provide an extension spring on the spindle so that it can be lifted as it is by the spindle lowered into the spindle. Further, the holding device can be configured by two-stage upper and lower sandwiches that are alternately opened and closed.

[0007]

When the spindle descends together with the support shaft, the spindle enters the spacer pipe and lifts it. If an extension spring is provided on the spindle, the spacer will not easily fall off when lifted. The spindle, which has thus captured the spacer pipe, then descends toward the shell, pierces the shell with a cone, and lifts it.

[0008] This time, it descends toward the wire supported upward by the clamping device. At this time, the lever mechanism works, the sleeve slides down, and the captured spacers and shells are brushed down, which is skewered into the wire. Thus,
The shell and the spacer are inserted one after another into the wire.

[0009]

An embodiment of the present invention will be described with reference to the drawings. As shown in FIGS. 2, 3, and 4, the machine frame 10 is located below the work table 12, and the support shaft 11 is supported by the machine frame 10.
Extend upward through the work table 12. Three arms 13 are radially attached to the upper end of the support shaft, and a spindle 15 is attached downward at the tip of each arm 13.

The machine frame 10 is provided with a lifting drive (not shown) for raising and lowering the support shaft 11 and a rotation drive (not shown) for rotating the support shaft by 120 degrees. With these driving devices, the support shaft 11 repeats a motion of rotating by 120 degrees, descending a fixed distance, and ascending to the original position. When the support shaft 11 rotates by 120 degrees, the three spindles 15 become three working points A, B, and C.
, And each spindle moves downward and upward at three working points A, B, and C with the vertical movement of the support shaft.

As shown in FIG. 5, a cone 16 having a sharp tip is integrally formed below each spindle 15. The cone 16 is formed thinner than the spindle body 15. The diameter of the cone 16 is 4 mm.

A sleeve 17 is slidably mounted on the spindle 15, and a coil spring 19 for urging the sleeve upward is contracted between the spindle 15 and the sleeve 17. The lower end of the coil spring 19 bears on a ring 20 fitted in the groove of the spindle 15 and the upper end of the spring bears on a cap 21 of the sleeve.

The lower part of the spindle 15 is provided with an extension spring 2 for firmly capturing the spacer 3 so as not to drop it.
Attach 2. The extension spring is made of a piano wire, which is passed through a hole 23 made in the spindle, and both ends are inserted into a groove 25 formed in the longitudinal direction along the inner peripheral surface of the sleeve 17.

In order to drop the spacer 3 and the shell 1 captured by the spindle 15 onto the wire, a lever mechanism 26 for pushing down the sleeve 17 is provided. That is, each arm 13
Is provided with a bracket 27, on which the lever 29 is rotatably supported (FIGS. 3 and 4). The member 30 against which the lever 29 abuts is set up only at the work point C.

Next, the operation of this machine will be described. At the work point A on the work table, an automatic feeder 31 is placed as shown in the right half of FIG. 3 and FIG. 6, and the spacer (vinyl pipe) 3 is automatically supplied by this. When the support shaft 11 is lowered, the spindle 15 enters the front row of the spacers arranged in the feeder 31, and the expansion spring 22 contracts,
As shown by a chain line in the figure, the spacer 3 is captured. Spindle 1
When 1 rises, the spacer 3 rises with the spindle 15 while being captured by the extension spring 22. When the first row of spacers is captured by the spindle and taken away, the next spacer is pushed out to the front row.

Next, the support shaft rotates by 120 degrees, another spacer comes to the work point A, and the same operation is performed. on the other hand,
The spindle 15 holding the spacer 3 at the work point A comes to the work point B. As shown in the left half of FIG. 3, at the work point B, the receiving table 32 is fixed on the work table 12. The cradle 32 is a dish-shaped frame made of a round bar. The scallop shell 1 is placed on the cradle 32. Here, spacer 3
The spindle 15 holding the nozzle descends. Then, cone 1
6 pierces the shell 1 and the spindle 15 rises,
The shell 1 rises while sticking to the spindle. In addition,
Place the next shell on the empty cradle 32 and wait for the next spindle to come.

Thus, the spindle 11 is rotated by 120 degrees and the spacer 1 and the shell 1 are captured at the point B.
5 comes to work point C. The work point C is located off the work table 12, and as shown in FIG. 4, the end of the wire 1 is held upward by a holding device 33 provided on the side surface of the machine frame 10. The holding device 33 includes upper and lower sandwiches 34a and 34b. As shown in FIG. 7, these pinches 34 are composed of a pair of jaws 37, 37 extending from spur gears 36, 36 meshing with each other. When a driving gear 39 meshing with one of the gears is driven by a motor (not shown), the jaws 34 Open and close. These pinches 34a, 34b
Automatically opens and closes in conjunction with the support shaft 11, and when one is open, the other is always closed, and one end of the wire is always interposed between the two ends.

Below the pinch 34, there is a hooking member 35 having a V-shaped notch, which can hold the wire so as to bite into the notch.

At this work point C, as shown in FIG. 4, a contact member 30 is erected on the work table, and when the arm 13 is slightly lowered together with the support shaft 11, the inner end of the lever 29 abuts on the member 30. The lever 29 pivots about the support point of the bracket 27, and the outer end of the lever 29 pushes the cap 21 of the sleeve downward. Then, the coil spring 19 is compressed and the sleeve 17 descends along the spindle 15 (see also FIG. 5). At this time, the two legs of the extension spring 22 are put into the groove 25 of the sleeve.

Thus, the sleeve is lowered, and the spacer 3 and the shell 1 captured by the spindle 15 are pushed downward. The extruded spacer and shell fall out of the spindle, are inserted and captured by the wire 2 waiting therebelow, and rest on the closed uppermost pinch 34a. The spindle 15 having the shell and spacer lowered in this way returns to the work point A again, and repeats the same work.

On the other hand, at the working point C, the uppermost pinch 34a
Is opened, the second-stage pinch 34b is closed, and the shell and the spacer are dropped from the uppermost stage 34a onto the second-stage pinch 34b,
Again, the uppermost clamp 34a is closed, and the second clamp 34b is closed.
Open and drop the spacer and shell further down, thus waiting for the next spindle. In this way, the shell 1 and the spacer 3 are inserted into the wire 2 one after another.

[0018]

According to the first aspect of the present invention, when the spindle is lowered, the shell is pierced by the conical tip and the shell is lifted, and then, when the spindle is lowered, the lever mechanism operates. Then, slide the sleeve down, drop the captured shell down, and catch it with the end of the wire pinched upwards. The passing operation can be performed continuously without manual operation, and the work efficiency can be remarkably improved as compared with the conventional manual operation.

Since the expansion spring is provided at the lower portion of the spindle, the spacer can be captured by piercing the spindle, so that the operation of passing the spacer through the wire can be automated. Can be.

According to a third aspect of the present invention, the wire clamping device is constituted by upper and lower clamps which are alternately opened and closed with each other. The spacer can be sent down.
