Description

[Detailed Description of the Invention] [Objective of the Invention] (Industrial Application Field) The present invention relates to a device for clamping articles that are amorphous and easily deformed, such as peeled shrimp, without damaging the articles. This invention relates to a clamping device that can accurately clamp at the center.

(Prior art) Shumai with peeled shrimp placed in the center of the top has been known for a long time, but since peeled shrimp are irregularly shaped and easily deformed, the conventional method was to place them by hand. ing.

(Problems to be Solved by the Invention) In the conventional method described above, the peeled shrimp are manually placed on the grilled shrimp transported on a belt conveyor, which makes the work unsightly, and it is difficult to place the peeled shrimp on the grilled shrimp. There are problems such as the possibility of the peeled shrimp falling from the grilled sale if one touches the peeled shrimp that has already been placed on the grilled sale. Also,
In order to improve its marketability, the peeled shrimp had to be placed in the center of the shumai, which was also a cumbersome process.

The present invention has been made in consideration of these points, and an object of the present invention is to provide a clamping device that can accurately clamp an irregularly shaped and easily deformable article at the center without damaging it.

[Structure of the invention]

(Means for Solving the Problem) As a means for achieving the above object, the present invention provides a plurality of flexible fingers arranged on the circumference so as to surround an article to be clamped, and a bushing that expands its diameter by elastically deforming the bushing, a gripping means having an actuator for driving the bushing, an article recess in which the article to be clamped is placed, and a clamping means provided around each of the four article portions, A mounting table having a finger recess into which the sex finger is loosely fitted is provided.

(Function) In the clamp device according to the present invention, an item such as peeled shrimp is placed in the item recess of the mounting table. On the other hand, each flexible finger of the gripping means is expanded in diameter by a bush driven by an actuator, and in this state the gripping means is lowered onto the article recess. As a result, the tip of each flexible finger is loosely fitted into each finger recess, and the article in the article recess is surrounded by each flexible finger.

Therefore, the bushing is reversely operated by driving the actuator, and each flexible finger is reduced in diameter by elastic return.

This ensures that the item is clamped in the center of each flexible finger.

(Example) Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

1 to 5 show an example of a clamp device according to the present invention, and this clamp device is composed of a gripping means 1 and a mounting table 2. As shown in FIG.

As shown in FIGS. 1, 3, 4 and 5, the gripping means 1 includes, for example, six needles arranged at equal intervals on the circumference so as to surround the peeled shrimp 3 to be clamped. Each of these needle-like fingers 4 is fixed to a block 5 at its proximal end.

Each needle-like finger 4 is made of a flexible material such as spring steel, and its tip side is shaped like a dogleg toward the center, as shown in FIGS. 1 and 5. Plastically processed.

As shown in FIGS. 1 and 3, a cylindrical bush 6 is disposed in the center of these needle fingers 4. It is attached to the tip of the rod 7a of the cylinder 7.

The bush 6 is mounted and pushed a from the block 5 by the expansion operation of the air cylinder 7, and the diameter of each needle finger 4 in the contracted diameter state is expanded by elastic deformation.

On the other hand, as shown in FIGS. 2(a), 3(b), 3, and 4, the mounting table 2 is provided with, for example, four circular product parts 8 in which the peeled shrimp 3 are accommodated. Around the article recess 8, finger recesses 9 in the form of elongated holes, for example, are provided, into which the needle fingers 4 are loosely fitted when the gripping means 1 is lowered onto the article recess 8.

Next, the operation of this embodiment will be explained.

When peeling and clamping the shrimp 3, the peeled shrimp 3 fed in chunks onto the mounting table 2 are peeled one by one by applying vibrations to the mounting table 2 or by scratching the top of the mounting table 2 with a scraper. It is accommodated in the article recess 8.

Next, the air cylinder 7 is operated to extend, and the bush 6 is pushed out from the mounting block 5. Then, each of the needle fingers 4, which had been reduced in diameter as shown in FIG. 1, expands in diameter due to elastic deformation, as shown in FIGS. 3 and 4.

Next, the gripping means 1 is lowered onto the article recess 8, and the third
As shown in the figure, the tip of each needle finger 4 is inserted into the finger recess 9. As a result, the peeled shrimp 3 housed in the product recess 8 is surrounded by the needle fingers 4.

Next, the air cylinder 7 is contracted and the bush 6 is drawn into the mounting block 5. Then, each needle-like finger 4 contracts in diameter due to elastic return, and the peeled shrimp 3 is clamped by each needle-like finger 4. Then, when the gripping means 1 is raised, the peeled shrimp 3 clamped between the needle fingers 4 is taken out from the article recess 8, as shown in FIG. The removed peeler 3 is transported to a burner (not shown), and placed on the burner by releasing the clamp.

In this way, since the peeled shrimp 3 is surrounded and clamped by the plurality of needle-like fingers 4, it can be securely clamped at the center of the gripping means 1, and when it is placed on grilled shrimp. , it can be placed accurately in the center of the shumai.

Moreover, since the peeled shrimp 3 is clamped by the elastic force of the needle-like fingers 4, it can be reliably clamped even if it is amorphous, soft and easily deformed.

Moreover, since the peeled shrimp 3 is clamped by the gripping means 1 while being accommodated in the article recess 8 of the mounting table 2,
The positioning of the peeled shrimp 3 can be performed accurately, and there is no problem such as the needle fingers 4 sticking into the peeled shrimp 3 and damaging them.

FIG. 6 shows an example of a shumai manufacturing machine incorporating the clamp device. This shumai making machine is composed of a shumai molding machine 11 and a shrimp topping machine 12, which are incorporated into the clamp device and the shrimp topping machine 12.

The shumai forming machine 11 kneads minced meat and chopped green onions, wraps the mixture in a thin wheat flour skin, and forms shumai in sequence. It is designed to be transported from the left side to the right side.

On the other hand, the shrimp topping machine 12, as shown in FIG.
