Vertical conveyor

Vertical conveyors are systems of conveyor technology and are used in the internal logistics to convey product streams upwards or downwards. Vertical conveyors are commonly found in the pre-combustion zone of a high- bay warehouse. They usually carry them doing a certain loading equipment or a specific group. With a vertical conveyor one or more levels of a conveyor system ( floors ) are interconnected.

A solution commonly used are climbing or Senkbänder. Such a belt conveyor, which is mounted at a certain angle, in order to bridge a difference in height, has the advantage that a certain distance is also covered. One disadvantage is, however, that while a lot of floor space is lost because the device along with the necessary support in accordance with claim much space. By using a product conveyor or vertical conveyor can be bridged with a smaller footprint, a larger height difference. In vertical conveyors there is a choice between a continuous conveyor (continuous conveyor) or intermittent conveyor ( discontinuous conveyor).

Intermittent conveyor

A discontinuous conveyor takes the product with the help of a platform or mounted on this platform roller conveyor or a belt conveyor and transmits this platform subsequently to another level. Such conveyor due to the cycle time required for the input and output, respectively for the up and downward movement, is useful only for low flow rates.

The movement takes place in two axes:

  • Y = vertical direction ( stroke unit )
  • Z = Gangquerrichung ( load-bearing unit )

The mechanism consists of:

  • The frame, which is firmly connected with the building. On the frame is the lifting gear ( rope or chain drive ) and the guide for the lifting carriage.
  • The lifting of said load receiving means ( LAM) is mounted. The lifting carriage is equipped with a device to prevent a crash when using rope or chain breakage ( safety gear ).

Continuous handling

At higher flow rates a continuous conveyor are better suited. In this group there are two different solutions: the spiral conveyor or continuous product elevator. Both solutions can handle multiple products. In an upright position of products a continuous product conveyor can be used, which is available in two versions: L- conveyor ( conveyor Matt ) and fork sponsor.

Spiral Conveyor

A screw conveyor has the advantage that it can be used with a minimum of control software costs. He can also operate at very high throughputs and depending on the manufacturer at high speeds. It requires little space, because there is no upstream and downstream technology is needed to separate the products. Although required by the vertical transport due to the revolutions that takes the conveyor belt, but a certain transport time, the spiral conveyor can also serve to absorb a large quantity of goods, is as usable as goods buffer. On the continuous conveying surface any products can be funded from the envelope to the traveling block. A product is supported on a spiral conveyor only at two corners. This is due to the angle of climb and to the radius in which the conveyor belt is mounted. When a product during transportation requires a flat support, the use of a spiral conveyor is not possible. In addition, the drive motor of a spiral conveyor must always be controlled by a frequency controller to prevent excessive wear of the conveyor belt. Also it should be noted that products must not bear against each other when typing. If the products are applied at the input against each other, the product may build up, which can lead to a defect on the conveyor belt. Also the products have to be centered enough for most spiral conveyors, because the eccentric load on the conveyor belt can lead to excessive wear. Should the product from whatever reason build up, the probability is very high that the slats of the conveyor belt break, which can lead to a significant loss of production throughout the production system, which is associated with enormous additional costs.

L- conveyor or conveyor Matt

An L- conveyor or conveyor Matt is a product conveyor in which the products are on a carrier that are suspended between some chains. Thereby the risk of product contamination is significant when conventional chains are used. Such a product conveyor may have the disadvantage that it requires a larger tax expense, but the space required compared to a spiral conveyor is considerably less. Also, the difference in height, which can be bridged with only one drive motor is virtually unlimited. To bridge major differences in height for spiral conveyors, it is necessary to install several systems over the other. Another disadvantage of an L- conveyor or conveyor Matt is difficult to monitor product transition at the input, a defective product intake can lead to a greater consequential damages. So are - similar to the spiral conveyor - significant additional costs to be expected due to production loss.

Fork conveyor

A fork conveyor provides more flexibility in the mounting options as a L-Förderer/Mattenförderer or a spiral conveyor. A fork is a product conveyor conveyor which transfers the product with a fork from a conveyor and reseating on another conveyor at a different level. Such a fork conveyor offers the possibility also products at an angle of 90 degrees or issue. This increases the opportunities at the input and output combinations. Because the product carriers can be moved into or out of the conveyor, a fork lift can be used as the vertical sorting. In such a sorting may at any desired level a product can be input and output, and it can be transported by one and the same product conveyor both upwards as well as downwards. The performance, and therefore also the energy consumption of the actuator is in an open-ended conveyor significantly lower than other systems because only the product to be transported, and keep the forks to each other in the ascending and descending member are in equilibrium. Another difference between the fork conveyor and an L - conveyor or conveyor Matt is the complexity of the controller. In an L- conveyor or conveyor Matt the input and output must be running completely in sync, while this is not necessary with a fork conveyor. This leads to a control system which is considerably simpler.
