1. The traffic cop is a mechanical device with spring loaded arms and cams located at the junction of two powered conveyor lines and prevents the flow of carton traffic on one line from interfering with the flow on the adjacent line. In other words, it eliminates collision of cartons arriving at the junction simultaneously. If possible, the two conveyors should be of the live roller type.

2. Case stops of blade and roller type are available as hand operated and foot operated. The air cylinder operated type is available as the roller type only. The blades or rollers are located between the rollers on the live roller or gravity conveyors only. They cannot be used in the middle of a belt conveyor, for obvious reasons.

3. Turning wheels are used at the junction of a branch line to a main line to insure proper carton orientation and to prevent cartons from falling off the conveyor during the course of the transfer.

4. Angle end stop is mounted to the ends of the conveyor side frames to prevent the continued flow of cartons on the conveyor from falling off of the conveyor.

5. Guard rails are available in many shapes and sizes. Their purpose is to prevent cartons from falling off the conveyor and they must be used on all overhead conveyors.

6. Ball transfers consist of a large steel ball riding on a bed of smaller balls all contained within a steel stamping to hold and support the configuration together. We utilize a pattern arrangement of ball transfers on a steel bed in a conveyor line to permit cases to be manually positioned or rotated easily.

7. "Y" Switch of skatewheel design provides a simple method of converging or diverging cartons. Consult the Hytrol General Catalog for a description and photo.

8. Spur curve switch of skatewheel design also provides a simple method of converging or diverging cartons. Again consult the Hytrol General Catalog.

9. Carton push-offs come in various sizes and designs. All push-offs simply push a carton at right angles to the original direction of flow. The overhead push-off is a high speed air cylinder actuated unit which can cycle up to 40 times per minute and can push carton with weights up to a maximum of 150 lbs. The medium duty horizontal push-off can push up to 300 lbs. and the heavy duty over 300 lbs. A horizontal push-off will cycle considerable less than the 40 cycles per minute available with the overhead unit.

10. Pop-up wheel diverter is specifically designed for use in the 190-ACC Accumulating conveyor. It provides for high speed automatic diverting of cartons onto a 30 degree spur. It consists of three rows of 2 1/2 inch diameter powered wheels, the mechanism of which is raised and lowered pneumatically. It can handle cartons of 150 lb. maximum weight up to 40 cycles per minute maximum. A description and photo is in you Hytrol General Catalog.

11. High speed diverter uses a powered diverting belt and can handle maximum weight cartons of 200 lbs. each. It is best used for rapid singulation and diverting. See the Hytrol General Catalog.

12. The powered turn-table is used when two parallel lines must be close together. The minimum turning radius is much less than our standard roller or even powered curves.

13. The manually operated turn-table simply consists of a given length of conveyor on a revolving mechanism, which allows the conveyor to be manually turned and positioned for "inline" flow of products. It is used where curves are unable to fit into the system. Pneumatic and motor indexing turntables are also available.

14. Plows can only be used to divert to a 30 degree spur from a main line. In addition to the manual1y positioned plow, Hytrol has the pneumatic positioned plow as well as the V-belt motorized and pneumatic positioned unit.

15. Manual Vertical Gates for gravity lines are available and the maximum length of gate is determined by the weight of the conveyor to be lifted. Gates are used to provide access through a conveyor line.

16. Spring Balanced Gate allows the use of heavier gates than with manual gates with the use of tension springs adjusted to provide a minimum weight lift.

17. Horizontal Swing Gates with castered supports can also be supplied. The conveyor in this instance may be powered as well as gravity.

18. Jump transfers are devices set between rollers of gravity or live roller conveyor to transfer the product at right angels from the conveyor. They perform the same function as the push-offs under more controlled circumstances. Hytrol has available the skatewheel transfer, the powered V-belt transfer and the powered chain transfer. In most instances, air bags are used to raise and lower the transfer.
