Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cloth sheet holding apparatus which is applied to a transfer device such as a robot or a cargo handling vehicle and is used when transferring a cloth sheet. . 2. Description of the Related Art Conventionally, in a steel mill, as shown in FIG. 5 , manufactured wire coils A are stacked in a bale and stocked. At this time, a cloth sheet B is interposed between the wire rods A so that they do not come into contact with each other and are not damaged. That is, as shown in FIG. 6 , a plurality of cloth sheets B are placed on a pallet C, and a wire coil A before being piled up on a pallet C is placed on a table D to be in the vicinity thereof. The worker E was picking up the cloth sheets B on the pallet C one by one and hung it on the wire coil A. [0003] However, since such work is performed manually, there is a drawback that the efficiency is extremely poor. For this reason, for example, it is conceivable to mechanize this work using a transfer device such as a robot,
A vacuum suction device usually mounted on a transfer device such as a robot cannot suction and hold a cloth sheet. This is because the fabric sheet is flexible and breathable and has a non-smooth surface. Therefore, an appearance of a cloth sheet holding device that can be attached to a transfer device such as a robot and can reliably hold a cloth sheet has been desired. The present invention has been made in view of the above-mentioned problems, and was created in order to solve this problem.
An object of the present invention is to provide a cloth sheet holding device capable of securely holding a cloth sheet. The cloth sheet holding apparatus of the present invention basically comprises a base, left and right needles which can pierce the cloth sheet, and each needle made of cloth with respect to the base. A moving means for moving the cloth sheet from a holding position where it stabs and holds the sheet to an open position where the cloth sheet is dropped and opened. [0005] In the cloth sheet holding device, the left and right needles are moved to the open position by the moving means. The fabric sheet holding device thus constructed is lowered onto the uppermost one of the many stacked fabric sheets, and the left and right needles are brought to the holding position by the moving means. Then, each needle is pierced into the uppermost one of the plurality of stacked fabric sheets, and the fabric sheet is held in tension. Therefore, when the cloth sheet holding device is raised and moved in such a state, only one cloth sheet is lifted and moved to another place. Then, when the needle has moved to the predetermined position, each needle body is set to the open position by the moving means. Then, the fabric sheet is dropped and released by being relaxed and coming out of each needle body. The moving means includes a left and right moving body movable in the left and right direction with respect to the base body, and a swinging body provided on each moving body so as to be swingable about an axis in the front-rear direction and having a needle body attached downward. A regulating body provided on each moving body to regulate the swinging movement of the oscillating body, and a moving driving device for oscillating each oscillating body with respect to each moving body and moving each moving body with respect to the base. You can do it. With this configuration, the needle can be inserted and removed in a vertical state with respect to the cloth sheet, so that the needle can be easily inserted into and removed from the cloth sheet. In addition, since the movement of the moving body and the swinging movement of the swinging body can be performed by a single moving driving device, so-called shared use is possible, which is extremely rational. Embodiments of the present invention will be described below with reference to the drawings. Figure 1 is a front view showing the open position of the onset Ming fabric sheet holding device. FIG. 2 is a view similar to FIG. 1 showing a position halfway between an open position and a holding position. FIG. 3 is a view similar to FIG. 1 showing a holding position. FIG. 4 is a schematic front view showing a transfer device to which the cloth sheet holding device is applied. The main part of the cloth sheet holding apparatus 1 is composed of a base 2, needles 3, and moving means 4. The base 2 serves as a basic part of the cloth sheet holding device 1, and in this example, left and right (right and left in FIG. 1).
It has a long columnar shape in the direction, and as shown in FIG. The transfer equipment 30 includes a main body 3 mounted on the ground.
1 and an arm 32 provided on the upper part of the arm 32 so as to be capable of turning and raising.
A base member 2 of the cloth sheet holding device 1 is swingably attached to the pallet C via a plurality of cloth sheets B, and a wire coil A placed on a mounting table D by picking up a large number of the cloth sheets B one by one from above. It can be hung on top of.
The cloth sheet B has a flat rectangular shape with a predetermined thickness t (about 2 to 3 mm) and a size, and is manufactured using a cloth just like judo. Of course, it is not limited to such a thing,
It goes without saying that it includes something similar to this. The needles 3 are left and right that can pierce the cloth sheet B. In this example, the length of the needle body 3 is such that one cloth sheet B can be pierced. The moving means 4 moves the needles 3 from the holding position where the needles 3 pierce and hold the cloth sheet B with respect to the base 2 to the open position where the cloth sheet B is dropped and opened. A left and right moving body 5 that can move in the left and right direction with respect to the base body 2, a rocking body 6 that is provided on each moving body 5 so as to be able to rock around a longitudinal axis, and has a needle body 3 attached downward; A restrictor 7 provided on the moving body 5 for restricting the rocking of the rocking body 6; a movement for rocking each rocking body 6 with respect to each moving body 5 and moving each moving body 5 with respect to the base 2; And a drive unit 8. The oscillating body 6 includes the moving body 5
The upper part is pivotally mounted on the upper part so as to be able to swing around a longitudinal axis. The needle bodies 3 are provided downward at the lower part of the rocking body 6, and a plurality of the needle bodies 3 are provided at predetermined intervals in the front-rear direction in accordance with the length of the cloth sheet B in the front-rear direction.
A pair of regulating bodies 7 are provided at respective extreme positions so that the swinging body 6 can swing by a predetermined angle θ (45 °) from the vertical position to the obliquely downward direction. The movement driving device 8 is provided between the lower middle part of the base 2 and the middle part of the rocking body 6, and is a fluid pressure cylinder. Next, the operation will be described based on such a configuration. The cloth sheet holding device 1 is, as shown in FIG.
The right and left rocking bodies 6 and the needle body 3 are vertically moved by the moving driving device 8 of the moving means 4 to the open position. The cloth sheet holding device 1 thus configured is lowered on the uppermost cloth sheet B stacked on the pallet C in large numbers. Then, the left and right needle bodies 3 pierce the uppermost fabric sheet B. If the needle body 3 stabbed-out impact, actuate the mobile drive unit 8 of the mobile unit 4. Then, as shown in FIG. 2, the swinging body 6 is swung by a predetermined angle θ with respect to the moving body 5 to be in an obliquely outward and downward state, and further swinging is regulated by the regulating body 7. At this time, since each needle body 3 is in a diagonally outer and lower state, the cloth sheet B is slightly tensioned to be in an engaged state. Further, when the movement driving device 8 is operated, the oscillating body 6 and the needle body 3 are moved.
As is shown in FIG. 3, as shown in FIG. 3, the moving body 5 and the subsequent bodies are moved outward with respect to the base 2, and the left and right needle bodies 3 are set to the holding positions. Then, the cloth sheet B is straightened and does not fall off from each needle body 3. Therefore,
When the cloth sheet holding device 1 is raised by the transfer device 30 in such a state, only one cloth sheet B is lifted. Then, if it is moved to a predetermined position by the transfer device 30, each needle 3 is moved by the moving means 4 in the reverse manner as described above.
