Abstract
The vibratory feeder utilizes a releasable attachment mechanism for connecting a feed tray to a vibrator for ease of removal and installation. The attachment mechanism has a first coupling in the form of z-blocks which when pressed together align the feed tray with the vibrator and firmly affix the tray against motion toward and away from the vibrator at the coupling. A second coupling displaced from the first coupling utilizes two pin blocks which are locked together by two press-fit pins. The pin blocks, when locked together, firmly fix the feed tray to the vibrator at the second coupling and simultaneously press the Z-blocks together at the first coupling.
Claims14
A vibratory feeder comprising:
- a feed tray for feeding product in the tray in a feed direction toward a discharge opening in the tray,
- vibrator means having a vibrated base plate for generating and transmitting vibrations predominantly in a given direction to the feed tray and product therein;
- and
- releasable attachment means for connecting the feed tray to and releasing the feed tray from the base plate of the vibrator means including,
- a first coupling having two parts which when pressed in together in a direction parallel to the feed direction firmly affix the feed tray to the base plate at the first coupling and simultaneously align the feed direction of the tray with respect to the given direction of the vibrator means, and
- a second coupling displaced parallel to the feed direction from the first coupling, and having two parts which when locked together firmly fix the feed tray to the base plate at the second coupling and simultaneously press the two parts of the first coupling together in the feed direction.
In a vibratory feeder having an elongated feed tray for feeding product from one end of the tray in a generally horizontal feed direction toward a discharge point at the other end of the tray, and a vibrator including a base plate driven with vibratory motions so as to advance the product in the tray in the feed direction, the improvement comprising:
- a manually releasable mechanism for attaching the feed tray to and detaching the feed tray from the base plate including,
- a first coupling having two parts which are separable in a direction generally parallel to the feed direction and which, when held against separation, also fix the tray vertically with respect to the vibrator base plate at the first coupling and simultaneously align the feed tray with respect to the base plate;
- and
- a second coupling having two parts which, when locked together, hold the two parts of the first coupling together against separation in the direction generally parallel to the feed direction and fix the tray vertically and in the feed direction with respect to the base plate at the second coupling.
