Abstract

(57) [Abstract] [Structure] The present invention provides a vacuum suction device that feeds and removes products by suctioning air during processing of plate materials. It is characterized in that it is constituted by a ball that opens and closes the arranged air flow path. [Effects] According to the present invention, there is no need for pre-processes such as replacing suction ports depending on the shape of the product in the vacuum suction device, and the number of suction ports can be increased due to the simple structure. It can handle even heavy products, and there is no need to use different equipment depending on the product, making work more efficient.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention relates to a vacuum suction device used for feeding and removing material in the processing of plate materials, etc. Ru.

0002

[Conventional technology]

Conventionally, a vacuum suction device or electric power was used to feed and remove plate materials during plate processing. A device using magnets is used, and the vacuum suction device has the structure shown in Figure 5. there were. That is, in FIG. 5, when the needle 11 is pushed up by the product, When the nozzle 12 opens and air is sucked from the suction port 13, the inside of the nozzle 12 This created a negative pressure that absorbed the product.

0003

[Problem that the idea aims to solve]

However, with the above-mentioned conventional technology, depending on the material, shape, etc. of the product, vacuum suction equipment cannot be used. It is necessary to use a vacuum suction device or an electromagnetic device. If there is a hole on the product near the part where the needle 11 hits, If it extends to the inside of the pad, air will flow in from that area, causing negative The product could not be adsorbed because pressure could not be obtained. To prevent this, attach the suction port to the product. It is necessary to move it to a place without holes, which increases the number of work steps. there were.

0004

[Means to solve the problem]

The vacuum suction device of this invention supplies products by suctioning air when processing plate materials. In a vacuum suction device that removes wood and removes wood, the air flow path and the air - A button placed in the middle of the flow path that opens and closes the air flow path depending on the air flow. It is characterized by being composed of rules.

【Example】 Hereinafter, the present invention will be explained in detail based on examples. Figure 1 shows the truth in this invention. It is a sectional view showing an air suction device, showing a member 1 having an air suction port 3 and a product suction device. There is a member 2 that has a suction port 4 for attaching the The diameter is larger than the opening 3 or the suction opening 4, and the ball 5 is inserted into it. ing. An elastic pad is placed on the side of member 2 that comes into contact with the product to improve adhesion to the product. Kit 6 is installed. In addition, the member 2 has grooves 7 cut in several places following the suction port 4. It is.

[0006] Here, if there is no product at the suction port 4 as shown in Figure 1, air will be released from the suction port 3. When suction starts, air is supplied from the suction port 4 into the air flow path 8, and the suction port Air flowing in from 4 passes through groove 7 and exits from suction port 3. this At this time, if the air flow rate is above a certain level, the air flow path 8 is The ball 5 is pushed up toward the suction port 3 by the air flow and abuts against the member 1. Otherwise, the suction port 3 will be blocked as shown in FIG. In this state, the suction port 4 Since no air flows into the suction port 3 and negative pressure is obtained on the suction port 3 side, the ball 5 An upward force acts on the ball 5, which holds the suction port 3 while air continues to be sucked. It will remain blocked. Therefore, the negative force on the suction port 3 side is maintained, so the other suction ports It does not affect the adsorption power of. When the suction is stopped, the ball 5 is moved by its own weight. and falls to the member 2 side, returning to the state before starting suction.

[0007] Next, as shown in Figure 3, the product 9 is placed at the suction port 4, and the suction port 4 is completely blocked. If there is, even if air suction is started from suction port 3, air from suction port 4 will be Since there is no inflow, the air flow does not push up the ball 5, and the air - Channel 8 remains open. Therefore, negative pressure can also be obtained within the air flow path 8, so Product adsorption can be performed. When the suction is stopped, the pressure inside the air flow path 8 is You will have to go back and release the product.

[0008] In addition, if the hole 10 of the product covers the suction port 4 as shown in Figure 4, the air flow When the amount of input is large, the ball 5 is pushed up by the air flow as shown in Figure 2. Since the ball 5 blocks the suction port 3, it does not affect the suction force at other suction ports. do not have. When the amount of air flowing in is small, the air flow does not push up the ball 5. This is not possible, and air will leak to the suction port 3 side, but at this time, other suction ports It has little effect on the suction force at the suction port, so the device as a whole is capable of suctioning the product. be able to.

[0009]

[Effect of the idea]

The vacuum suction device of this invention supplies products by suctioning air when processing plate materials. In a vacuum suction device that removes wood and wood, the parts that make up the air flow path and the air flow It consists of a ball placed in the middle of the air flow path that opens and closes the air flow path. Depending on the position of the hole in the product, etc., work processes such as replacing the suction port may be required. The product processing time can be shortened and the number of suction ports can be increased due to the simple structure. This makes it possible to handle heavier products, and therefore, The effect is that there is no need to use different equipment depending on the product, which improves work efficiency. There is fruit.
