Abstract

PURPOSE:To enable a fabric to be held positively with no damage made to the fabric allowing it to be laminated orderly on a fabric setting table by providing a drive mechanism where a pair of gripping members, each of which has a needle that is pointed to the opposite direction to that of the other party, is allowed to move to the opposite direction each other so as to allow the needle to hold and release the fabric. CONSTITUTION:A plunger 17 is lowered with an electromagnetic solenoid 16 energized, and link shafts 13 and 14 are allowed to move overcoming a coiled spring 21 to each of directions which is opposite in such a way that they are separated each other along guide members 15. This movement allows gripping members 8 and 9 to move to each of the directions which is opposite. This permits the pin of a gripping needle 12 of the gripping members 8 and 9 to pick up fibers of a fabric A allowing the pin to pierce into the fibers. Then the fabric A can be taken up. Subsequently, a fabric gripping device 3 is lifted up by an arm 2, and is moved to the stated position. Then, the plunger 17 is raised up by energy of the spring 21 with the electromagnetic solenoid de-energized allowing the gripping member 8 and 9 to move to each of the directions which is opposite. This allows the pin of the gripping needle 11 and 12 to be pulled out of the fabric A permitting the fabric to be released and laminated orderly.

Description

[Detailed description of the invention] Purpose of the invention (industrial application field) This invention lifts the dough placed on the top surface of the dough table,
This invention relates to a fabric gripping device that performs a transfer operation to another position.

(Prior Art) Conventionally, as shown in FIG. 11, this type of dough gripping device has a pair of gripping rods 43 having several needles 41 fixed to their lower ends and a shaft 42 attached to the middle part so as to be openable and closable. After the needle 41 is pierced into the fabric A by pressing it against the upper surface of the fabric A, both gripping rods 43 are opened to apply tension to the fabric A, and the fabric A is grasped several sheets at a time.

(Problems to be Solved by the Invention) However, with the above-mentioned conventional dough gripping device, the dough A is damaged because it is pulled, and the spreading force of the gripping rod 43 is adjusted depending on the thickness and type of the dough A. In addition, there was a problem in that the entire device became larger.

The object of the present invention is to provide a dough gripping device that solves the above-mentioned problems.

Structure of the Invention (Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention provides a holding member having a needle portion extending obliquely downward, and a needle portion extending downward in a direction opposite to the needle portion.

A round hole 10a is provided at one end of the base material 10, and a long hole 10b is provided at the other end, and each of the round hole 10a and the long hole 10b is provided with a connecting shaft 13. 1
4 is inserted. This connecting shaft 13.14 has a long hole 10.
b, and said gripping member 8.9 is relatively movable in the horizontal plane in the opposite direction of its longitudinal direction.

Guide members 15 are fixed to lower portions on both sides of the pair of side walls 4c, 4c of the case 4, and support the connecting shafts 13, 14 so as to be slidable across the racks.

As shown in FIG. 2, an electromagnetic solenoid 16 is housed and fixed at its upper part in the housing cylinder 5, and a plunger 17 is inserted through the center of the solenoid 16 so as to be able to move up and down, and is always moved upwardly by a coil spring (not shown). is being energized. A connecting shaft 18 is inserted through the lower end of the plunger 17 in parallel to the longitudinal direction of the case 4. Each end of this connecting shaft 18 has a connecting link 1 between it and the connecting shaft 1.3.14.
9°20 is installed. And electromagnetic solenoid 1
6, the plunger 17, the connecting shafts 13, 14, 18, and the connecting links 19,20 constitute a drive mechanism for the gripping member 8.9.

Further, between both ends of the two connecting shafts 13 and 14, both connecting shafts 1
3. Coil springs 21 and 2 for urging the gripping members 8 and 9 toward each other and returning the gripping members 8 and 9 to the retracted position.
1 is installed.

Next, the operation of the dough gripping device 3 configured as described above will be explained.

Now, in order to transfer the dough to another place after grasping and lifting one piece (or two or more pieces) of dough A on the dough table 1,
First, the fabric gripping device 3 is lowered by the arm 2 from the position shown by the two-dot chain line in FIG. 4, and the fabric A is slightly pressed as shown by the solid line in the same figure.

Next, as shown in FIG. 5, when the electromagnetic solenoid 16 is excited and the plunger 17 is moved downward, this force is transferred to the connecting shaft
The connecting shaft 13 via the connecting link 19.20 attached to the
．． 14. Both connecting shafts 13, 14 slide on guide member 15 against the urging force of coil springs 21, 21, and both connecting shafts 13, 14 are moved away from each other.

As the connecting shafts 13 and 14 move, the gripping member 9 is moved in the direction of the arrow P in the figure, and the gripping member 8 is moved in the direction of the arrow Q in the figure. At this time, the gripping needle 11.1 of the gripping member 8°9
The second needle portions 11b and 12b are caught on the fibers of the fabric A and pierced between the fibers, and the fabric A is scooped up and held at a plurality of locations by the gripping members 8.9.

Next, the dough gripping device 3 is lifted by the arm 2 and moved to a predetermined position. When the dough gripping device 3 is lowered in this position or the electromagnetic solenoid 16 is demagnetized while it is in the lifted state, the plunger 17 is moved upward by the biasing force of a coil spring (not shown). This plunger 1
Due to the upward movement of 7, the connecting shaft 18 is pulled upward, and the upper ends of both connecting links 19, 20 are pulled up. Also, at this time, the coil springs 2 attached to both the connecting shafts 13 and 14
The urging forces 1 and 21 move the connecting shafts 13 and 14 toward each other, and with this movement, the gripping member 8 is moved in the direction of arrow P, and the gripping member 9 is moved in the direction of arrow Q.

As both gripping members 8.9 move, the needle parts 11b and 12b of the gripping needles 11.12 are pulled out from between the fibers of the fabric A, and the gripping of the fabric A by the gripping needles 11.12 is released, and the fabric A is neatly placed in a predetermined position. Laminated.

Now, in this embodiment, there are a plurality of needle parts 11b.

The gripping needle 11.12 formed with the shape 12b is fitted and fixed onto the base material 10 to form the gripping member 8.9, and the gripping member 8.
．． The gripping needles 11 and 12 of 9 are provided so that they can grip the fabric A when horizontally moved in the direction toward each other, and release the grip on the fabric A when they are horizontally moved in the direction away from each other. In contrast, it is possible to grip the fabric A reliably without applying tension to the fabric A and damaging the fabric A.
Even after the dough is transferred, the dough can be placed on the table 1 in an orderly manner. Additionally, compared to conventional dough gripping devices that use vertical gripping rods, the device as a whole can be made more compact.

Note that the present invention is not limited to the above embodiments, and may be implemented as follows.
