Claims
- 1. A wrapping machine comprising:
- (a) wrapping film transporting means for transporting wrapping film to a wrapping area;
- (b) wrapping film folding means for folding said wrapping film at its side portions to thereby wrap an object to be wrapped under the condition that said object to be wrapped is disposed just under said wrapping film stretched at said wrapping area;
- (c) a push-up member for pushing up a part of said wrapping film to a wrapping position prior to an operation to wrap said object to be wrapped,
- said push-up member comprising a frame having a size larger than an outline of said object to be wrapped and a pair of vertically movable vertical rods for supporting said frame from its lower end and at its opposite side;
- (d) delivery means for pushing up said object to be wrapped to said wrapping position after the pushing up of said wrapping film; and
- (e) adjusting means for adjusting a pushing-up amount of said push-up member, said adjusting means comprising a driving member for driving said push-up means and a transmitting member interposed between said driving member and said push-up member to transmit operation of said driving member to said push-up member, said driving member and said transmitting member being cooperatively intercoupled to adjust said pushing amount of said push-up member and moving said push-up member by an adjusted amount
- said driving and transmitting members comprising a cam and a first lever mounted to be rotated on a first shaft as said cam rotates, means coupling said vertical rods to be vertically moved as said first lever rotates, and means adjusting said cam and first lever with respect to their relative position in their closing and separating direction to each other.
- 2. A wrapping machine according to claim 1, in which said adjusting means further comprises a pair of second levers pivotally connected at one end thereof to lower end portions of said vertical rods respectively arranged to be vertically rotated on a second shaft, a connection rod arranged to be vertically rotated on said second shaft integrally with said second levers, and a male screw rod pivotally connected at its one end to a free end of said connection rod to extend substantially horizontally and to be rotatable circumferentially, said first lever being connected at its free end to said male screw rod at a connection position on said male screw rod whereby said connection position is adjustable along a determined length of said male screw rod.
- 3. A wrapping machine according to claim 2, in which said adjusting means further comprises a guide tube connected to the other end of said male screw rod so as to extend in the same direction as said male screw rod such that the connection between said guide tube and said male screw rod is allowed to be vertically bent, and a rotary shaft partly inserted into said guide tube whereby said rotary shaft and said guide tube are lengthwise movable relative to each other.
- 4. A wrapping machine according to claim 3, wherein said guide tube comprises a slot extending along substantially the entire length thereof, and further comprising a slide pin slidably engaged with said guide slot formed at one end of said rotary rod and a handle attached to the other end of said rotary rod and rotatable integrally with said rotary rod.
- 5. A wrapping machine comprising:
- (a) wrapping film transporting means for transporting wrapping film to a wrapping area;
- (b) wrapping film folding means for folding said wrapping film at its side portions to thereby wrap an object to be wrapped under the condition that said object to be wrapped is disposed must under said wrapping film stretched at said wrapping area;
- (c) a push-up member for pushing up a part of said wrapping film to a wrapping position prior to an operation to wrap said object to be wrapped;
- (d) delivery means for pushing up said object to be wrapped to said wrapping position after the pushing up of said wrapping film; and
- (e) adjusting means for adjusting a pushing-up amount of said push-up member,
- said push-up member comprising a frame having a size larger than an outline of said object to be wrapped and a pair of vertically movable vertical rods for supporting said frame from its lower end and at its opposite sides,
- said adjusting means including at least one cylinder having a vertically adjustable attachment position, a guide member attached to an end of a piston rod of said cylinder and formed with a lengthwise extending guide slot, and at least one lever pivotally connected at its one end to lower end portions of said vertical rods and arranaged to be vertically rotated on a second shaft at its other end, said lever being provided with a pin slidably inserted in said guide slot so as to engage therewith.
- 6. A wrapping machine comprising:
- (a) wrapping film transporting means for transporting wrapping film to a wrapping area;
- (b) wrapping film folding means for folding said wrapping film at its side portions to thereby wrap an object to be wrapped under the condition that said object to be wrapped is disposed must under said wrapping film stretched at said wrapping area;
- (c) a push-up member for pushing up a part of said wrapping film to a wrapping position prior to an operation to wrap said object to be wrapped;
- (d) delivery means for pushing up said object to be wrapped to said wrapping position after the pushing up of said wrapping film; and
- (e) adjusting means for adjusting a pushing-up amount of said push-up member,
- said push-up member comprising a frame having a size larger than an outline of said object to be wrapped and a pair of vertically movable vertical rods for supporting said frame from its lower end and at its opposite sides,
- said adjusting means including at least one rack provided at a lower portion of said vertical rods, a pinion geared with said rack, and an electric motor arranged so that rotation of said motor is controllable and arranged to drive said pinion to rotate to thereby vertically move said push-up member.
