Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
277 words
In an apparatus for feeding and wrapping products comprising a wrapping machine having means for operating said wrapping machine and a device for feeding products to said wrapping machine which device includes a first belt conveyor for receiving products from a dispensary apparatus, a second belt conveyor connecting said first conveyor to said wrapping machine, a stop element located on and at the end of said second conveyor adjacent said wrapping machine, and first and second control means selectively positioned along said second conveyor at increased spacing, respectively, from said wrapping machine, said first and second control means each having sensing means for sensing the absence or presence of products on said second conveyor, the improvement which comprises: first drive means for driving said first conveyor at either a high speed or a low speed; second drive means for driving said second conveyor at a continuous speed in the same direction as said first conveyor; switch means connected between said first control means and said operating means for said wrapping machine to deactivate said operating means when said first control means senses the absence of products on said second conveyor; and control circuitry connected between said second control means and said first drive means for controlling the driving speed of said first drive means in response to the output from said second control means, wherein said control circuitry causes said first drive means to operate at high speed when said second control means senses the absence of products on said second conveyor and causes said first drive means to operate at low speed when said second control means senses the presence of products on said second conveyor.
Claim 2
Dependent Claim

In an apparatus for feeding and wrapping products comprising a wrapping machine having means for operating said wrapping machine and a device for feeding products to said wrapping machine which device includes a first belt conveyor for receiving products from a dispensary apparatus, a second belt conveyor connecting said first conveyor to said wrapping machine, a stop element located on and at the end of said second conveyor adjacent said wrapping machine, and first and second control means selectively positioned along said second conveyor at increased spacing, respectively, from said wrapping machine, said first and second control means each having sensing means for sensing the absence or presence of products on said second conveyor, the improvement which comprises: first drive means for driving said first conveyor at either a high speed or a low speed; second drive means for driving said second conveyor at a continuous speed in the same direction as said first conveyor; switch means connected between said first control means and said operating means for said wrapping machine to deactivate said operating means when said first control means senses the absence of products on said second conveyor; and control circuitry connected between said second control means and said first drive means for controlling the driving speed of said first drive means in response to the output from said second control means, wherein said control circuitry causes said first drive means to operate at high speed when said second control means senses the absence of products on said second conveyor and causes said first drive means to operate at low speed when said second control means senses the presence of products on said second conveyor.
Claim 3
Dependent Claim
25 words
The apparatus according to claim 1, wherein the speed of said second conveyor is intermediate the high and the low speeds for said first conveyor.
Claim 4
Dependent Claim
46 words

Claim 5
Dependent Claim
22 words
The apparatus according to claim 3, wherein the second delay timer circuit is a delayed closing and opening type delay timer circuit.
Claim 6
Dependent Claim
21 words
The apparatus according to claim 1, wherein said control circuitry includes a delay timer circuit and a speed controlling change-over switch.
