Abstract
Abstract An automatic bottle handling machine comprises a storage hopper for bottles in random orientation, a plurality of conveyor channels having conveyors extending between the hopper and a corresponding plurality of drop chutes and selective reversing devices for turning around neck first bottles before reaching the drop chutes. A sensor in each drop chute detects the prolonged presence of a bottle therein to stop the corresponding conveyor. A yoke member below each sensor indefinitely arrests the downward movement of an incorrectly oriented bottle or a defective bottle having a spur or flash on the bottom thereof to stop traffic in the corresponding drop chute and thereby stop the supply of bottles by the corresponding conveyor until the offending bottle has been removed by the operator. Another sensor for detecting a crushed bottle may be provided at the upper end of each drop chute for similarly stopping the corresponding conveyor.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
157 words
An apparatus for automatic handling of hollow bodies, said apparatus comprising a plurality of conveyor channels having a conveyor extending to the respective upper ends of a corresponding plurality of drop chutes, a delivery conveyor disposed below and in vertical alignment with said plurality of drop chutes, and selective arresting means at the lower ends of said drop chutes for contacting each hollow body moving towards said delivery conveyor, said selective arresting means being of the yoke type and being engageable with the leading end of a correctly oriented hollow body to move out of the path of travel of the hollow body in the respective drop chute to said delivery conveyor and engageable with the leading end of an incorrectly oriented hollow body and to snare the same and indefinitely hold back the snared incorrectly oriented hollow body whereby all hollow bodies within the drop chute upstream of the snared hollow body will be held back.
Claim 2
Independent Claim
157 words
An apparatus for automatic handling of hollow bodies, said apparatus comprising a plurality of conveyor channels having a conveyor extending to the respective upper ends of a corresponding plurality of drop chutes, a delivery conveyor disposed below and in vertical alignment with said plurality of drop chutes, and selective arresting means at the lower ends of said drop chutes for contacting each hollow body moving towards said delivery conveyor, said selective arresting means being of the yoke type and being engageable with the leading end of a correctly oriented hollow body to move out of the path of travel of the hollow body in the respective drop chute to said delivery conveyor and engageable with the leading end of an incorrectly oriented hollow body and to snare the same and indefinitely hold back the snared incorrectly oriented hollow body whereby all hollow bodies within the drop chute upstream of the snared hollow body will be held back.
Claim 3
Independent Claim
202 words
An apparatus for automatic handling and orientation of hollow bodies, said apparatus comprising a hopper for storing hollow bodies in random orientation, a plurality of conveyor channels having conveyors extending into said hopper, selective reversing means adapted to turn around incorrectly oriented hollow bodies in said conveyor channels, a plurality of drop chutes disposed in vertical alignment at the ends of said conveyor channel remote from said hopper, a delivery conveyor disposed in vertical alignment with and below said plurality of drop chutes, each of said drop chutes having sensing means for detecting the prolonged presence of a hollow body in its drop chute and in response thereto providing a control signal for stopping the conveyor of the associated conveyor channel, the improvement comprising arresting means of the yoke type in each of said drop chutes disposed below the associated sensing means for snaring and indefinitely holding back an incorrectly oriented hollow body, whereby the holding back of the snared incorrectly oriented hollow body by one of said arresting means eventually causes the prolonged presence of a hollow body in the associated drop chute to be detected by the associated sensing means and thereby stopping the conveyor of its associated conveyor channel.
Claim 4
Independent Claim
202 words
An apparatus for automatic handling and orientation of hollow bodies, said apparatus comprising a hopper for storing hollow bodies in random orientation, a plurality of conveyor channels having conveyors extending into said hopper, selective reversing means adapted to turn around incorrectly oriented hollow bodies in said conveyor channels, a plurality of drop chutes disposed in vertical alignment at the ends of said conveyor channel remote from said hopper, a delivery conveyor disposed in vertical alignment with and below said plurality of drop chutes, each of said drop chutes having sensing means for detecting the prolonged presence of a hollow body in its drop chute and in response thereto providing a control signal for stopping the conveyor of the associated conveyor channel, the improvement comprising arresting means of the yoke type in each of said drop chutes disposed below the associated sensing means for snaring and indefinitely holding back an incorrectly oriented hollow body, whereby the holding back of the snared incorrectly oriented hollow body by one of said arresting means eventually causes the prolonged presence of a hollow body in the associated drop chute to be detected by the associated sensing means and thereby stopping the conveyor of its associated conveyor channel.
Claim 5
Dependent Claim
143 words
The apparatus of claim 1, wherein said hollow bodies being bottles with necks and normally proceeding bottom first in said drop chutes, wherein said yoke of each of said arresting means comprises a yoke member configured to receive the neck of a bottle proceeding neck first in its drop chute, said yoke members being freely pivotally mounted between a standby position in which said yoke members are disposed substantially transversely of their drop chutes and interposed in the pathways of bottles therein, and an operative position to which said yoke members are pushed by the bottoms of bottom first bottles to clear the same and to which said yoke members are driven by the necks of neck first bottles received in said yoke members holding back the neck first bottles, and biasing means for urging said yoke members constantly to their standby position.
Claim 6
Dependent Claim
