Tower storage system

Intelligent solutions for the storage of sheet metal plates and long goods optimize material flow, improve machine utilization and improve work safety and process reliability. Through the compact design of a tower storage system, it is thereby possible, for example, to optimally utilize valuable production space as an intermediate warehouse, buffer storage or for material stockage.

Our components guarantee smooth processes and ensure safety. Typical areas of use are access guarding at dangerous areas of machines and systems. Our inductive and optical sensors check and monitor the presence and position of sheet metal plates or stacks. And they optimize the process flow, thereby ensuring high availability of the machine or system.

[01] Access guarding, one side
csm_apic_mt_mld_metal_storage_access_guarding_wl_8aeebea4db (1)

Requirement:
Access to a dangerous area at a machine or system is to be guarded. To enable simple entry and exit of material, optoelectronic safety sensors are to be used.

Solution:
The MLD 300 / 500 multiple light beam safety devices offer affordable access guarding solutions. The transceiver models with an operating range of up to 8 m are especially easy to install. For wide-area guarding, transmitter/receiver models are available with a range of up to 70 m. 

[02] Integration of safety sensors
csm_apic_mt_msi400_integration_of_safety_sensors_v2_wl_orig_893820e3eb

Requirement:
Multiple safety sensors must be integrated into the machine or system control. Functions such as a time delay for releasing a locking device or signal connections are also to be configured.

Solution:
The basic module of the MSI 400 expandable safety control already has 24 safe inputs/outputs as well as an Ethernet interface with Industrial Ethernet protocols. The safety control can be configured quickly and efficiently using the license‑free configuration software MSI.designer.

[03] Projection monitoring
3_APIC_MT_HT25_Overhang_control_Metal_bearing_wl Kopie

Requirement:
To avoid collisions with the load receptacle during the storage and retrieval process, a check is to be performed to determine whether sheet metal plates protrude at the loading area. To reliably detect even slightly rotated sheet metal plates, the check is to be performed at multiple points.

Solution:
The HT 25C diffuse reflection sensors with background suppression ensure reliable presence control. With their degrees of protection IP 67 and IP 69K as well as the active ambient light suppression, the extremely compact sensors offer a very high level of flexibility and reliability. 

[04] Presence control for sheet metal
4_APIC_MT_FT328_Metal_bearing_wl Kopie

Requirement:
After the pick & place unit deposits the sheet metal plate, the presence of the sheet metal plate is to be checked at the storage location to allow the subsequent process step to start, e.g., infeed of the material to the machine.

Solution:
The FT 328i energetic diffuse sensors in the sturdy plastic housing with metal thread facilitate robust material detection. The simple adaptation to the material using the teach button enables fast and simple commissioning. Available as an economical alternative are the inductive switches of the IS 200 series.

[05] Presence control for sheet metal
5_APIC_MT_HT46C_Presence_control_Metal_bearing_wl Kopie

Requirement:
After the sheet metal plate is picked up by the pick & place unit, the presence of the sheet metal plate in the unit is to be constantly monitored to ensure a smooth process flow.

Solution:
The HT 46C and HT 25C diffuse reflection sensors with background suppression ensure reliable presence control. Models with various light-spot geometries offer optimum adaptation to the application. Flexible mounting brackets, cables and IO-Link models are also available.

[06] Positioning
6_APIC_MT_ODSL30_Metal_bearing_wl Kopie

Requirement:
To position the load receptacle in the tower rack, the distance to a specified reference point is to be determined.

Solution:
With the focused laser, the ODSL 30 optical distance sensors offer operating ranges of up to 65 meters and, with an absolute measurement accuracy of ± 2 mm, are ideal for precise positioning.
