Description

[Detailed description of the invention] The present invention relates to a product conveying device that conveys individual products to a device that bundles multiple individual products together and packages them.

Conventionally, individually packaged products such as rice crackers are held between a pair of belts that move in the same direction at the position where the products are held, and the product is passed from the discharge section of the individual product packaging device to the receiving port of the product constant packaging device. Product conveyance devices such as belt conveyors are being considered.

In such a belt conveyor, the distance between the product receiving ends of the pair of belts was constant. However,
Packed rice crackers of inconsistent shape vary in thickness, so it may not be possible to reliably receive the packaged rice crackers discharged from the discharge section of the individual packaging device between a pair of belts, and if the belt Even if we can accept the product in between,
When the product is received between the belts, the rice crackers collide with the belt support rollers and break, which tends to result in defective packaging in the product constant packaging device, reducing productivity.

The purpose of this invention is to provide a product conveyance device that solves these problems.In configuring a product conveyance device that conveys multiple individual products to a packaging device, it is possible to The conveyor is divided into a conveyor that transports the products in buckets, and a conveyor that transports the products in buckets, and the conveyor that grips and transports the products is equipped with a pair of belt clamping devices on the product receiving side. The ends of each product receiving side of the belt clamping device are moved relatively close to each other.
The conveyor is configured to be separable so that the receiving side ends of each product are relatively separated from each other when the products are carried in, and the conveyor is configured to transport the products in buckets in a predetermined number of buckets. A conveying device equipped with a sorting device provided with a subdivision plate that goes in and out of the bucket is disposed inside, and the product transfer side end of the conveyor that clamps and conveys the product is connected to the bucket. It is disposed above the bucket of the conveyor that conveys a predetermined number of conveyors in batches.

With this configuration, in a device that conveys products such as rice crackers that vary in thickness and are easily fragile, the product can be reliably received between the belts, and the shape of the product can be maintained. Furthermore, it becomes possible to reliably transport a predetermined number of products together to the product constant packaging device, and to transport the predetermined number of products to the product constant packaging device while maintaining the required posture.
