Poly-V Roller Conveyor

Vention’s pre-assembled poly-v roller conveyor sections were designed to ensure an easy initial setup and long-lasting performance. From a simple straight segment to a full conveyor application, it has never been so easy to design a conveyor system. All our sections are compatible with each other, as well as our full Vention’s ecosystem.
All sections are equipped with provisions to add sensors and cable management cut-outs and are compatible with many Vention accessories, including modules, leg adjustment, angle adjustment, pneumatic pushers, and end stops.

Straight sections

Our straight sections are available in 2 widths (585 and 945 mm) and a length of 1575 mm. These sections come unpowered and the Motor Mount Bracket (MO-CV-031-0006) and Motor Adaptor (MO-CV-039-0001) can be added to them as required.  This is because two segments can be powered by a common motor at their junction.

Table below shows all variations of straight sections.

Note: Width is the between the frames width (BF width) of the rollers. For the full width of the conveyor add another 90mm.

Skewed sections

Vention’s new Poly-V conveyor family includes a series of skewed sections designed to align packages against a conveyor guide while supporting accumulation. This allows boxes to be consolidated on one side of the conveyor and buffered until a full group has formed, an ideal setup for end-of-line palletizing. Additionally, these rollers feature accumulation sleeves that increase buffer capacity and extend the equipment's service life. All four sections are available in left- and right-hand configurations.

Applications

Conveyors are used to move loads from one point to another. Our poly-v conveyor family offers possibilities to create applications that vary from material transport to accumulation. Visit our design library for sample designs of different applications. Here are a few examples:

Material Transport

Accumulation for end-of line packaging

Technical Specifications

*Note: The capacity to transport material is highly dependent on the rigidity of the payload and therefore the generated rolling resistance. A rigid plastic tote bin or wooded box or pallet will yield much higher load capacity than a single layer cardboard box. For example the conveyance of wooden pallet or totes weighing up to 500kg is possible but when using carboard boxes a limit of 150kg per zone should be used. A zone is defined as a grouping of rollers or conveyors driven by a common motor.

Accessories

1) Leg adjustments

The two following leg and conveyor adjustments are available and fully compatible with this o-ring conveyor family.

1. Height Adjustment bracket: This bracket allows a quick and simple way to adjust the conveyor to any existing equipment. The max translation is 150 mm

2. Angle Adjustment bracket: The angle adjustment bracket is a key part for all gravity conveyors, while also allowing to adjust the conveyor to existing equipment.

2) Modules, sensors, and cable management

1. Sensor Mounts

Each C-channel of Vention’s Poly-V conveyor family is equipped with specific placement for sensors, making it easy to install without additional hardware. It is also possible to use any existing hole, with the addition of the sensor bracket (CE-HW-001-0003).

2. I/O and E-Stop Module

There are several options for installing the I/O and E-Stop modules, either using the vertical extrusions or using a simple extrusion structure attached beneath the conveyor c-channel, as shown below.

3. Cable Management

The C-Channel brackets is equipped with cutouts to allow easy cable management coming from sensors, modules, and motor cables to prevent chaffing and offer a clean integration setup. It is also possible to use zip ties to secure cables using the designated holes along the C-Channel.

3) Guides

a) Mounting bracket as side guard

The C-channels mounting the rollers are versatile and can also be used as a guiding system on all sections. The c-channel can simply be superposed over the actual conveyor section. Associated fasteners are included in each C-Channel to ensure a safe installation.

Another great perk of having a channel as a side guide is being able to install sensors underneath the top bracket in its designated cutouts. This will allow maximum protection of the sensor.

b) Flexible guides (straight sections only)

Flexible guards (ST-PN-020-XXXX) come in multiple lengths and can be cut to specific lengths if needed. They are used to index or funnel boxes along a conveyor during material handling operations. Using our well-known round extrusion, the flexible guide provides an adjustable solution for flexible guide. For more details, refer to the Flexible Conveyor Guide section of the Material Handling Datasheet.

4) Pneumatic pushers

In palletizing applications, to have the box on a certain location on the conveyor at the end of the line and close to the robot to pick up, a pneumatic pusher is used to push the box to the side of the conveyor. It is possible to install the pneumatic pusher in a simple way on Vention’s new poly-v conveyors. Follow these steps for a quick and easy design:

1. Install a short 45x45 extrusion on top of the conveyor c-channel using associated fasteners from the conveyor    

   • M8 serrated nuts (HW-FN-031-0002)

   • M8x18 mm screws (HW-FN-003-0018) and

   • M8 split washers (HW-WS-001-1003)

2. Design and install an additional leg made of extrusion, with the same height as the conveyor. The below image shows a T-shaped leg to hold the pusher.

3. Install the pusher on top of the conveyor and the additional leg.

5) End Stop

An end stop can be easily made out of two GP gussets (ST-GP-003-0005 or ST-GP-003-0001) and a 45x45 mm extrusion between them. It can be installed on top of the conveyor c-channels using the following fasteners:

1. M8x18 mm screws (HW-FN-003-0018) provided with the gussets

2. M8 Serrated Flange Locknut (HW-FN-031-0002) provided with the conveyor.

6) Motor Shaft Cover

This cover (MO-CV-031-0016) can be installed beneath the conveyor c-channel and in front of each motor as a safety guard In order to protect people from touching the motor shaft. It has a slot on top which makes it compatible with all straight, skewed and curved sections.

Assembly Instructions

Assembling the legs, anchoring, sensor installation and butt-joining conveyors are all same as our smart o-ring conveyor. Please refer to Assembly Instruction of smart o-ring conveyor for those. The following installation instructions are exclusively for poly-v conveyors.

1) Installing the motor mount and driver belt

1. Place the motor adaptor at the highest position and use four M6x18mm (HW-FN-005-1018) and four M6 washers (HW-WS-005-0001) to attach it to the motor mount of the conveyor.

   
   Note 1: Do not fully tighten them at this stage.
   Note 2: When installing the motor adaptor on the motor mount of the conveyor, the two M6 threaded holes on the side of the motor adaptor must be facing down (towards the ground) for tensioning in the next step.

1. Use two M6x70mm (HW-FN-005-1070) and two M6 washers (HW-WS-005-0001) at the location shown below on the Motor Mount (MO-CV-030-0008) and connect the screws to the threaded holes on the bottom of Motor Adaptor (MO-CV-029-0001).

   

1. Lower the 2 hanging poly-v belts onto the grooved shaft of the motor adaptor.

2. While having the four screws on the Motor Mount (MO-CV-030-0008) slots still loose, use the two M6x70mm (HW-FN-005-1070) screws to bring down the motor adaptor. The motor adaptor will slide down and create tension in the poly-v belts on the shaft.

3. Check that the alignment of the belt is straight and the poly-v belt is in the correct grooves on both the roller and the motor pulley.

4. When the motor mount is in its final position on the vertical slots, tighten the four M6x18mm screws (HW-FN-005-1018) to 9 -11 N.m.

2)Skewed sections cover Brackets

For covering the end gaps of skewed conveyors, a cover bracket and a smaller grooved roller can be installed at both ends of the conveyor. Table below shows the compatible cover bracket part numbers with each of the skewed conveyors.

Cover Bracket Installation

1. Place the cover bracket between the c-channels of the conveyor, parallel to the rollers, and connect it to the conveyor using the following associated fasteners. Torque the M8 screws to 15-18 N.m.    

   • 2x M8x18 mm screws (HW-FN-003-0018)

   • 2x M8 split washers (HW-WS-001-1003)

   • 2x M8 serrated nuts (HW-FN-031-0002)

2. Place the small roller (MO-CV-001-0135/0180) inside the cover into the shown location by inserting in the hex shaft of the small roller into the hex hole of the conveyor and then pressing the other side of the spring-loaded shaft into the hex hole of the cover bracket.

   

3. Note: The installation process is similar to all skewed configurations.

3) Motor shaft cover installation

Install the Motor Shaft Cover (MO-CV-031-0016) on the Motor Mount Bracket (MO-CV-031-0006) using the following associated fasteners. Torque the M3 screws to 1.2-1.4 N.m.

• 4x M3×6 mm screws (CE-FN-003-0006)

• 4x M3 split washers (CE-WS-003-0005)

Maintenance and Support

1- Maintenance

In case of failed poly-v belts, identify which side of the failed belt is closer to the start or end of a zone as all of the rollers will need to be removed. To remove the rollers, follow these steps:

1. Cut the failed poly-v belt if it is not already broken.

2. Uninstall the surrounding finger guards. The screws are M4s with washers.

3. Push in the spring-loaded hex shaft of the belt side of the rollers and remove all of the rollers between the end or beginning of the zone and the affected belt (green arrow).

4. Put the good belts to the side to be reused when reinstalled

   

5. Install the new belt and begin re-installing the roller into the c-channel. Use Vention’s roller installer tool (HW-TL-004-0002__2) to place the roller hex shaft back in the hex hole.

6. Repeat step 5 for all of the rollers that were removed.

7. Re-install all of the finger guards.

8. Double check that all of the belts are in the proper groves and they are not rubbing on each other.
