AN IMPROVED HORIZONTAL FLOW WRAP MACHINE FOR REORIENTING THE WRAPPED PACKETS

Abstract An improved horizontal flow wrap machine for reorienting the wrapped packets comprising of a pusher (4) for pushing the packet from the conveyor belt (14) into a pocketed wheel (3) characterized in that a striper plate (13) for easing out of the packet at 90° turn of the wheel.
Full Text FIELD OF INVENTION
This invention relates to an improved horizontal flow wrap machine for reorienting the wrapped packets from its discharge conveyor, for easy filling into cartons.
PRIOR ART
In a known horizontal flow wrap machine, product is wrapped in a scalable film with a central long seal and two end seals. This process is well known and does not need elaboration. Wrapped packets are finally discharged on a flat belt, from which the same is manually picked and
placed in cartons. However, this arrangement is associated with a disadvantage that, when the packets need to be reoriented for placement in open-top cartons, the packets are erected to stand on face. Thereafter, it is collated and placed in the box. This is a laborious process.

OBJECTS OF THE INVENTION
A primary object of the present invention is to propose an improved horizontal flow wrap machine which allows automatic erection and collation of the wrapped packets from the flat belt so that it is easy for a worker to lift these together and place directly into the container.
STATEMENT OF INVENTION
According to this invention there is provided an improved horizontal flow wrap machine for reorienting the wrapped packets comprising of a
t
pusher for pushing the packet from the conveyor belt into a pocketed wheel and a stripper plate for easing out of the packet at 90° turn of the wheel.
BRIEF DESCRITPION OF THE ACCOMPANYING DRAWINGS
Further objects and advantages of this invention will be more apparent from the ensuing description when read in conjunction with the accompanying drawings and wherein:

Fig. 1 shows: Top view of known horizontal flow wrapping machine. Fig.2 shows : An exemplary embodiment of the present invention.
DETAILED DESCRIPTION OF THE INVENTION WITH REFERENCE TO THE ACCOMPANYING DRAWINGS;
According to this invention, there is provided an improved horizontal flow wrap machine ,for reorienting the wrapped packets comprising a pusher for pushing the packet from the conveyor belt into a pocketed wheel and a stripper plate for easing out of the packet at 90° turn of the wheel.
Top view of a known horizontal flow wrap machine is shown in Fig. 1. Wrapped packets are discharged by means of conveyor belt (1) (fig. 1). The packet (4) (fig. 1) appears (1) in fig. 2 when seen from the front end as marked by an arrow in Fig. 1.
i
Reference may be made to fig. 2 wherein this packet is pushed to position (2) by means of pusher (4). This pusher is driven forward by means of parallel levers (5 & 6). Lever (5) is pushed by means of cam (11) through

its follower (9) mounted on lever (8) which is connected to lever (5) by link (10).
Lever (6) is pivoted on lever (7) which rotates by means of cam (12). In its horizontal position, lever (7) restrains pusher (4) to move horizontally because of the parallel link geometry.
This movement is utilized to push the packet forward as shown in fig. 2b. At the end of its stroke, pusher is lifted up (as shown in fig. 2(c) by rotating lever (7) and by means of cam (12). This allows the lever to clear
t
the incoming packet during its reverse movement.
In another embodiment of this invention crank mechanism can be used to impart reciprocating movement to lever (5).
In yet another embodiment of this invention a pneumatic cylinder is used to impart push to the packet.

In yet another embodiment of this invention overhead pusher mounted on roller chains is used to push the packet.
Packet thus pushed enters into a pocketed wheel (3) which is continuously rotating and timed with respect to the packet push to present easy entry of packets into the pockets of the wheel. Packet thus carried is eased out of the pocket at 90° turn of the wheel by means of a stripper plate (13). Packet in its upright position is pushed forward by the action of succeeding packet, so on and so forth, so that packets start collating in the desired upright position. Collated packets are conveyed by means of for example conveyor (14).
It is to be noted that the present invention is susceptible to modifications, adaptations and changes by those skilled in the art. Such variant embodiments employing the concepts and features of this invention are intended to be within the scope of the present invention, which is further set forth under the following claims:-








WE CLAIM:
1. An improved horizontal flow wrap machine for reorienting the wrapped packets comprising of a pusher (4) for pushing the packet from the conveyor belt (14) into a pocketed wheel (3) characterized in that a striper plate (13) for easing out of the packet at 90° turn of the wheel.
2. An improved horizontal flow wrap machine as claimed in claim 1, wherein the pusher (4) is driven forward by means of parallel levers (5 & 6).
3. An improved horizontal flow wrap machine as claimed in claim 1 or 2, wherein the lever (5) is pushed by means of cam (11) through its follower (9) mounted on lever (8), which is connected to the lever (5) by a link (10).
4. An improved horizontal flow wrap machine as claimed in any of the preceding claims, wherein lever (6) pivoted on lever (7), which rotates by means of cam (12).
5. An improved horizontal flow rap machine as claimed in any of the preceding claims, wherein crank mechanism is provides to impart reciprocating movement to the lever (5).
6. An improved horizontal flow wrap machine as claimed in any of the preceding claims, wherein a pneumatic cylinder is provided so as to impart push to the packet.
7. An improved horizontal flow wrap machine as claimed in any of the preceding claims, wherein an overhead pusher is mounted on roller chains so as to push the packet.
