Abstract

The invention relates to a clamping and conveying device. There are many manufacturing procedures in the production and processing of bottled water or bottled beverages, and the products need to be transferred or transported between different manufacturing procedures. To achieve this requirement, most of the fixtures are designed with a single cam guide rail to make the fixture swing And reset action to achieve the purpose of product transfer or delivery, when the fixture needs to make a large swing angle, the cam guide rail needs to have a large curvature change, but due to the extremely fast production speed, in the case of long-term high-speed operation , the cam guide rails are easy to wear and reduce the production efficiency; the present invention uses the mechanism design of the double cam guide rails, which can make the fixture make a sufficient swing angle while reducing the curvature change of the cam guide rails, thereby reducing the wear of the cam guide rails.

Description

Clamping and conveying equipment

The invention is a clamping conveying device.

The rise of capitalism advocates consumption. In response to the needs of the consumer market, product manufacturers have introduced more automated production equipment to enable them to produce more products within a limited time. For example, bottled water or bottled beverages in the consumer market have become unavailable to modern people. Therefore, manufacturers or equipment manufacturers have developed production equipment that can produce bottled water or bottled beverages in large quantities.

There are many processes and steps in the production of bottled water or bottled beverages. When moving between different processes, use such as the Republic of China Patent Publication No. I264370 "Clamping Mechanism of Stretch Blow Molding Machine" or such as the Republic of China Patent Publication No. M354606 "Bottle clamping device for filling machine capping device", which allows bottled water or bottled beverages or even empty bottles to be moved to the next process. This type of clamping mechanism is usually designed with a clamp combined with a cam guide rail, so that the clamp moves along the guide rail. Rotating on the cam plate, through the irregular shape of the cam guide rail, when the fixture is rotated to a specific position, it can perform swinging and reset actions.

However, due to the configuration of the production line, sometimes the fixture needs a larger swing angle. When using a single cam guide to control the swing angle of the fixture, the cam guide will have a large curvature change. Therefore, under long-term high-speed rotation, the guide The parts move in the cam guide rail with large curvature changes and guide the fixture to make a large swing angle, which will easily cause the cam disc to wear and cause the production line to require frequent maintenance and reduce production efficiency.

Therefore, in order to improve the production efficiency and prolong the service life of the cam disc and the guide, the present inventor proposes a clamping and conveying device, comprising: a cam disc, an inner guide rail and an outer guide rail, the inner guide rail and the The outer guide rail is arranged on the same plane, the inner guide rail and the outer guide rail are separated by a predetermined distance and do not intersect with each other, and both the inner guide rail and the outer guide rail are non-circular closed guide rails. A driving unit includes a driving disc, a telescoping member, an inner guide and an outer guide, and the driving disc is rotatably fixed on the inner side of the inner guide rail of the cam disc. The telescopic member is arranged radially around the rotating shaft of the driving disk, the inner guide is fixed on the telescopic member and arranged on the inner guide rail, the outer guide is arranged on the outer guide rail, and the inner guide The guide piece abuts against the bottom surface of the inner guide rail, and the outer guide piece abuts against the bottom surface of the outer guide rail. A clamp is pivotally connected to the telescopic member, and the outer guide is fixed on the clamp; when the drive plate drives the slider to rotate, the slider directly drives the inner guide and the clamp to rotate, and through the The fixture drives the outer guide to rotate, and the inner guide and the outer guide move on the inner guide rail and the outer guide respectively. When the inner guide passes through a path of curvature change, the inner guide The component drives the slider to move, and the slider will push the clamp to make the clamp rotate with the outer guide as the center of a circle.

Further, the telescoping member has a sliding block and a sliding rail, the sliding rail is fixed on the driving disk, and the sliding block is movably arranged on the sliding rail.

Further, the inner guide rail is a groove on the cam plate.

Further, the outer guide rail is a groove on the cam disc.

Further, the inner guide is rotatably fixed to the telescopic member.

Further, the inner guide is a roller.

Further, the outer guide is rotatably fixed to the clamp.

Further, the outer guide is a roller.

Further, the drive unit has a plurality of telescopic elements, a plurality of inner guides and a plurality of outer guides, and each telescopic element is arranged on the drive disk at equal intervals in a ring around the rotation axis of the drive disk. The guide pieces are respectively fixed on each telescopic piece and arranged on the inner guide rail, and each outer guide piece is arranged on the outer guide rail; there are a plurality of clamps pivotally connected to each telescopic piece respectively, and each The outer guides are respectively fixed on each fixture.

According to the above-mentioned technical features, the following effects can be achieved:

1. Use the clamping and conveying equipment of the present invention to cooperate with the product manufacturing process, so that the clamps can swing and reset according to the needs, so that the product can be transported from one process to the next after being transported by the clamping and conveying equipment of the present invention for processing.

2. Use the inner guide rail and the outer guide rail to control the swing angle of the fixture at the same time. The inner guide part and the outer guide part move on the inner guide rail and the outer guide rail with a small curvature change respectively, and the inner guide part and the outer guide part are moving The speed change is small, which can reduce the wear caused by the inner guide and the outer guide to the inner guide rail and the outer guide rail, thereby prolonging the maintenance cycle and improving production efficiency.

3. Use rollers as the inner and outer guides to move in the inner and outer guides. The inner and outer guides can rotate and move along the inner and outer guides respectively, which can reduce the inner guide The wear caused by the inner guide rail and the outer guide rail directly when the parts and the outer guide parts move in the inner guide rail and the outer guide rail respectively.

4. The grooves with closed curves are used on the cam disc as the inner guide rail and the outer guide rail, which is easy to assemble and maintain, and can reduce maintenance time.

5. Using multiple clamps with multiple expansion parts, multiple inner guides and multiple outer guides, the clamping and conveying equipment of the present invention can increase the number of items clamped per unit time, thereby improving production efficiency.
