Abstract
Abstract An insertion apparatus is provided for inserting continuously supplied products into containers. The insertion apparatus includes an ejection device which moves parallel to products along an endless conveyor system, and a curved directrix which is adapted to guide the ejection device in a direction which effects lateral movement of the products. The directrix is inclined relative to the direction of movement of the products, and a device is provided for bypassing movement of the ejection device with respect to the directrix so that the ejection device will move independently of the movement of the products.

Claims Analysis
Total Claims: 24
Claim 1
Independent Claim
144 words
An insertion apparatus for ejecting products which are continuously supplied into containers, said apparatus comprising: (a) ejection means arranged to move parallel to said products along an endless conveyor system; (b) a directrix adapted to guide said ejection means laterally shift to said products, said directrix being inclined relative to the direction of movement of said product line; and (c) means for bypassing the movement of said ejection means relative to said directrix whereby said ejection means moves independently thereof, said by passing means including a guide curve adapted to guide the movement of said ejection means relative to said directrix, said guide curve being defined by a groove formed in a cylinder casing mounted on a guide cylinder, said guide cylinder being rotatable, whereby rotation of said guide cylinder from a normal operating position will cause said ejection means to bypass said directrix.
Claim 2
Dependent Claim
144 words
An insertion apparatus for ejecting products which are continuously supplied into containers, said apparatus comprising: (a) ejection means arranged to move parallel to said products along an endless conveyor system; (b) a directrix adapted to guide said ejection means laterally shift to said products, said directrix being inclined relative to the direction of movement of said product line; and (c) means for bypassing the movement of said ejection means relative to said directrix whereby said ejection means moves independently thereof, said by passing means including a guide curve adapted to guide the movement of said ejection means relative to said directrix, said guide curve being defined by a groove formed in a cylinder casing mounted on a guide cylinder, said guide cylinder being rotatable, whereby rotation of said guide cylinder from a normal operating position will cause said ejection means to bypass said directrix.
Claim 3
Dependent Claim
28 words
The apparatus as defined by claim 1 wherein said guide curve is configured such that said ejection means is transported in a vibration-free manner through said guide curve.
Claim 4
Dependent Claim
21 words
The apparatus as defined by claim 1 wherein the configuration of said guide curve is defined by a higher order polynomial.
Claim 5
Dependent Claim
21 words
The apparatus as defined by claim 3 wherein the configuration of said guide curve is defined by a fifth order polynomial.
Claim 6
Dependent Claim
18 words
The apparatus as defined by claim 1 wherein said guide curve is milled out of a single element.
Claim 7
Dependent Claim
60 words
The apparatus as defined by claim 1 wherein said guide cylinder is mounted along an axis perpendicular to the direction of movement of said ejection means, said guide curve comprising means for reversing the direction of motion as said ejection means returns after ejecting said product, along a direction parallel to the edge of said guide cylinder, towards said directrix.
Claim 8
Dependent Claim
19 words
The apparatus as defined by claim 6 wherein said guide cylinder is rotatable through an angle of about 45°.
Claim 9
Dependent Claim
30 words
The apparatus as defined by claim 1 wherein said guide curve is linearly moveable and is adapted to guide a cam roller mounted on said ejection means toward said directrix.
Claim 10
Dependent Claim
18 words
The apparatus as defined by claim 1 further comprising means for adjusting the position of said guide curve.
Claim 11
Dependent Claim
23 words
The apparatus as defined by claim 9 wherein said means for adjusting the position of said guide curve includes a hydraulic cylinder-piston arrangement.
Claim 12
Dependent Claim
22 words
The apparatus as defined by claim 12 wherein said means for adjusting the position of said guide curve comprises an electromagnetic system.
Claim 13
Dependent Claim
37 words
The apparatus as defined by claim 1 wherein said directrix is mounted whereby said directrix is released and freely pivotable from its normal position as a result of an excessive force being exerted upon said ejection means.
Claim 14
Dependent Claim
14 words
The apparatus as defined by claim 12 further comprising means for pivoting said directrix.
Claim 15
Dependent Claim
19 words
The apparatus as defined by claim 13 wherein said means for pivoting said directrix is a fluid cylinder-piston system.
Claim 16
Dependent Claim
18 words
The apparatus as defined by claim 13 wherein said means for pivoting said directrix comprises an electromagnetic system.
Claim 17
Dependent Claim
38 words
The apparatus as defined by claim 14 further comprising maintenance means for maintaining said directrix in its normal operating position, said maintenance means permitting the release of said directrix when said directrix is subjected to an excess pressure.
Claim 18
Dependent Claim
66 words
The apparatus as defined by claim 16 wherein said maintenance means comprises a maintenance notch and a maintenance projection adapted to seat within said notch, and wherein said directrix is associated with said projection whereby when excessive force is exerted on said directrix, said directrix will be moved out of a normal position and will pivot said notch, thereby unseating said projection from within said notch.
Claim 19
Dependent Claim
16 words
The apparatus as defined by claim 17 wherein said projection is spring biased within said notch.
Claim 20
Dependent Claim
14 words
The apparatus as defined by claim 18 wherein said projection is a ball bearing.
Claim 21
Dependent Claim
27 words
The apparatus as defined by claim 16 wherein said maintenance means is positioned adjacent to a front plate of a frame in which said apparatus is mounted.
Claim 22
Dependent Claim
71 words
The apparatus as defined by claim 16 further comprising a lever associated with said maintenance means, said lever comprising a movable first electrical contact, said lever being mounted relative to a second electrical contact whereby when said directrix is moved, said lever will be raised or lowered by displacement of a projection positioned within a pivotable notch, thereby selectively establishing electrical contact between each of said first and second electrical contacts.
Claim 23
Dependent Claim
27 words
The apparatus as defined by claim 1 wherein said directrix is movable to an inactive position which is essentially parallel to the active position of said directrix.
Claim 24
Dependent Claim
33 words
The apparatus as defined by claim 22 further comprising two pivot arms adapted to pivotably support said directrix at spaced points along said directrix, and wherein each of said pivot arms is journal-mounted.
