Description

System for conveying pasta Technical Field The present invention relates to a system for conveying pasta products that provides continuous and slow conveyance. Background The pasta is usually picked up after pressing by a conveyor unit for conveying the pasta through a pasta dryer. For example, long pasta (such as pasta) is hung on a rod whose end is loosely lifted by the chain links of the chain conveyor. In an apparatus for producing elongated pasta, such as pasta, it is necessary to transfer the pasta from one conveyor unit to another. For example, the drying unit of such a device is designed for a plurality of passes of pasta through the space within the drying unit by means of different conveying units, for space reasons. Furthermore, pasta produced, for example, by extrusion must be transported to and transferred to the cutting unit. In particular in the case of wet pasta, pasta is particularly sensitive to shock, vibration or other jerky movements. Therefore, great care must be taken in transferring pasta from one conveyor unit to another to avoid damaging the pasta. In the prior art, this problem has not been satisfactorily solved. Transferring pasta (or pasta-suspended bars) from one conveyor unit to the next requires precise coordination of the movements of the individual conveyor units. Typically, this coordination requires that the conveyor units are intermittently moved, the latter conveyor unit only beginning to move when the previous conveyor unit has conveyed the element to be conveyed (e.g. the bar from which the pasta is suspended) to a certain position. This is described in, for example, GB1,048,163. Such delivery is disadvantageous for various reasons. When the element to be conveyed (for example a bar hanging pasta) is transferred from a first conveying unit (for example a swinging chain or chain conveyor) to a subsequent fixed conveying unit (for example a chain conveyor), the element to be conveyed is subjected to an initial impact. The downstream transport unit now starts moving and transports the element to the next transfer position (e.g. a scraping chain of a downstream transport unit such as a cutter) where the element is subjected to another impact during transfer. In this case, the conveying unit (chain conveyor, scraper chain) is intermittently moved (i.e. run-on-run). The rapid start of the conveying unit may cause impact to the components to be conveyed, be time-consuming compared to continuous operation, and may apply a load to the electrical components. In technical use, this system allows each machine to deliver approximately 11-12 bars per minute (from which the pasta is suspended). US2,965,214A describes a continuous conveying system in which the elements to be conveyed are transferred from one conveyor chain to the next by means of a rotating disc with gripping elements. The rotating disc is symmetrically arranged between the two conveyor chains and operated by means of planetary gears to prevent abrupt changes of direction of the gripping elements arranged on the rotating disc. However, such a conveying system requires a lot of space, which makes its installation in the equipment for producing elongated pasta challenging. Furthermore, the geometry of the transfer unit is challenging, requiring extremely high precision, making its installation time consuming. In US3,472,354 a conveyor system is described in which a conveyor is transported from one conveyor chain to a subsequent conveyor chain by means of a transport arm unit. The conveying system also comprises a planetary gear unit having the above-mentioned drawbacks. Disclosure of Invention The problem underlying the present invention is to provide a conveying system for a device for producing elongated pasta, such as pasta, which overcomes the drawbacks of the prior art and in particular enables smooth, efficient and continuous transfer of conveying elements from one conveying unit to another without abrupt changes in direction. This problem is solved by the conveying system according to the invention. The invention relates to a conveying system for a device for producing elongated pasta, such as pasta, comprising a first conveying unit, a second conveying unit and a transfer unit for transferring a conveying element from the first conveying unit to the second conveying unit, characterized in that the transfer unit comprises a rotatably mounted cam element with a gripping means and a fixedly arranged guide element with a surface section of approximately circular arc shape, wherein the cam element and the guide element are arranged relative to each other such that a conveying element, which is received by the gripping means of the cam element from the first conveying unit, can be moved along the surface section of approximately circular arc shape of the guide element due to the rotation of the cam element to a position in which the conveying element can be received by the second conveying unit.
