Step Feeder-Pusher Feeder for Pins -Bolts

I. Structural Overview – Side-by-Side Comparison

Funkcia	Vibračný miskový podávač	Pusher Feeder (Step Feeder / Horizontal Pusher)
Main structure	A spiral, cone‑shaped bowl mounted on a vibrating base	A hopper + a reciprocating pusher plate (or blade) sliding on a horizontal or inclined track
Drive mechanism	Electromagnetic drive + leaf springs (vibration)	Pneumatic cylinder, hydraulic cylinder, or electric motor + cam/ linkage
Part movement	Parts move upward along a spiral track via vibration (micro‑jumps)	Parts are pushed forward horizontally (or at an incline) by a reciprocating pusher plate
Orientation method	Passive – parts are oriented by mechanical tooling (wipers, slots, air jets) built into the track	Limited – parts are separated and pushed; orientation is often predefined by part geometry or downstream tooling
Wear parts	Leaf springs, electromagnet, track tooling, rubber mounts	Pusher plate, cylinder seals, slide rails, wear strips
Footprint	Compact – circular base (typically 300–1200 mm diameter)	Linear – longer footprint (typically 1–3 m in length, but narrower)
Typical height	Moderate – bowl height varies with diameter	Low – often compact in height (especially horizontal pushers)

II. Detailed Breakdown of Each Structure

A. Vibratory Bowl Feeder Structure

Bowl body – A stainless steel or aluminum cone with a spiral track inside.
Base unit – Contains the electromagnet, leaf springs, and armature.
Riadiaci systém – A controller adjusts amplitude and frequency.
Tooling – Wipers, slots, air jets, and step gaps are installed on the track to orient parts.
Linear feeder (optional) – A straight vibrating track attached to the bowl exit to transfer parts to the next machine.
Hopper (optional) – A large container above the bowl to hold bulk parts.

B. Pusher Feeder Structure

Hopper / magazine – A vertical or inclined bin that holds bulk parts in a stacked or layered arrangement.
Pusher plate / blade – A flat or contoured plate that moves back and forth to push the bottom‑most part out of the hopper.
Drive unit – A cylinder (pneumatic or hydraulic) or a motor‑driven cam mechanism that provides reciprocating motion.
Guide rails / track – Precision‑machined rails that guide the parts as they are pushed forward.
Separation mechanism – May include gates, fingers, or steps to separate stacked parts into single‑file flow.
Sensor / control – Optional sensors to detect part presence and synchronize pusher action with downstream equipment.

III. Visual / Operational Comparison

Aspect	Vibračný miskový podávač	Pusher Feeder
Motion type	Vibratory (high‑frequency, small‑amplitude)	Reciprocating linear motion (low‑frequency, longer‑stroke)
Part flow direction	Upward spiral (3D path)	Horizontal or slight incline (2D path)
Part state during feeding	Parts bounce, slide, and tumble – work in progress	Parts are pushed in a controlled, stable manner
Ability to orient parts	Yes – via built‑in tooling	Limited – generally no active orientation; relies on part shape or pre‑orientation
Sensitive to part weight	Yes – heavier parts need more drive power	No – weight is not a major limitation
Sensitive to part stickiness	Yes – sticky parts clog the track	No – mechanical pushing overcomes adhesion
Part damage risk	Moderate – impact and friction can scratch parts	Low – gentle pushing with minimal impact

IV. Structural Summary Table

Component / Feature	Vibračný miskový podávač	Pusher Feeder
Primary structure	Bowl + vibrating base	Hopper + pusher plate + rails
Drive principle	Electromagnetic vibration	Pneumatic / hydraulic / electric linear actuation
Part flow path	Spiral (upward)	Linear (horizontal or inclined)
Orientation	Mechanical tooling on track	Not built‑in (may need pre‑orientation)
Wear parts	Springs, coil, track, mounts	Pusher plate, cylinder seals, slide rails
Footprint	Compact (round)	Elongated (linear)
Height	Moderate (bowl height)	Low (flat layout)
Best‑suited parts	Small, rigid, dry, non‑sticky parts	Springs, O‑rings, heavy parts, sticky parts, fragile parts
Speed range	50–300+ parts/min	10–60 parts/min (typical)
Cost range	$1k–$8k (standard)	$2k–$10k (custom)

V. Key Structural Difference – In One Sentence

A vibratory bowl feeder uses vibration to move parts up a spiral track, while a pusher feeder uses a reciprocating mechanical plate to push parts along a linear path – the former is circular and passive, the latter is linear and active.
