FIELD OF INVENTION
The present invention provides an inline pusher assembly for pushing stacks of products having predetermined stack length. More particularly, the present invention relates to an inline pusher assembly for segregating stacks of biscuits standing on their edges and transferring the stack of biscuits to either of the following arrangements for further processing:
a. Drop Box/Drop Chute to Flight Bar Conveyor,
b. Overhead Careocell (Carrier Cell) or
c. Upward movement of the stack of biscuit.
BACKGROUND OF THE INVENTION
The inline pusher assembly is located parallel to a magazine that continuously supplies biscuits and the inline pusher assembly pushes the biscuit to form a stack having a predetermined stack length upon either of the following arrangements:
a. Drop Box/Drop Chute to Flight Bar Conveyor,
b. Overhead Careocell (Carrier Cell) or
c. Upward movement of the stack of biscuit.
The motion of the inline stack assembly in the existing mechanism is shown in figures 1 and 2.
In figure 1 shows a conventional cam based inline pusher assembly. Now referring to Figures 1(A) and 1(B), which represent the front view and the side view of the conventional cam based inline pusher assembly respectively, it can be noticed that the inline pusher (1) is coupled to a motor (7) through a linear bearing block (2), a link (3), two levers (4 and 5) and a cam (6). The motor rotates the cam which in turn passes the motion to the inline pusher through the levers, the link and the linear bearing block. The inline pusher assembly thus moves in the direction represented by the arrow and indicated by the numeral (8). Figure 1(C) shows the blown up view of the inline pusher (1) which is used in the inline pusher assembly shown in Figures 1 (A) and Figure 1 (B). As there are a number of components coupled between the inline pusher and the motor, the system is

quite complicated and lot of efforts are to be put for maintaining the system in workable condition.
Figure 2 shows an alternate construction of the inline pusher assembly conventionally used. Referring to figures 2(A) and 2(B), which represent the front view and the top view of the inline pusher assembly respectively, it can be noticed that the inline pusher (11) is coupled to the motor (12) through a link (13), lever (14), a reel roller (16) and a gear box (15). The inline pusher assembly thus moves in the direction represented by the arrow and indicated by the numeral (17). Figure 2 (C) shows the blown up view of the inline pusher (11) which is used in the inline pusher assembly shown in Figures 2 (A) and Figure 2 (B). This mechanism is also complicated and also, expensive. Thus, there exists a grave need to provide an alternative system for operating the inline pusher.
OBJECTS OF THE PRESENT INVENTION
The main object of the present invention is to provide an inline pusher assembly for segregating stacks of products standing on the edge.
Another object of the present invention is to provide a driving mechanism for the inline pusher assembly that overcomes the disadvantages of the earlier systems.

STATEMENT OF THE PRESENT INVENTION
Accordingly, the present invention provides an inline pusher assembly for pushing stacks of products having a predetermined stack length, the said assembly characterized by a driving means (21) selected from the group comprising of a geared box and an electric motor attached through a ball-screw assembly (22) to a reel roller (24) mounted with the inline pusher (23) for providing accurately controlled motion to the inline pusher, wherein the reel roller mounted with the inline pusher is coupled to the ball screw assembly through a linking means (25).
DETAILED DESCRIPTION OF THE PRESENT INVENTION
In order to overcome the disadvantages of the prior art described above, the present invention provides an inline pusher assembly for pushing stacks of products having a predetermined stack length, the said assembly comprising of a driving means (21) attached through a ball-screw assembly (22) to a reel roller (24) mounted with the inline pusher (23) for providing motion to the inline pusher.
More particularly, the present invention provides an inline pusher assembly for pushing stacks of products having a predetermined stack length, the said assembly characterized by

a driving means (21) selected from the group consisting of a geared box and an electric
motor attached through a ball-screw assembly (22) to a reel roller (24) mounted with the
