Insert machine
The present invention discloses an improved insert machine for inserting flat material into an open pocket and, more particularly, to a straight line insert machine employed for printed matter such as newspapers. The machine includes an all-electronic control system for controlling machine functions. The control system includes at least one central control computer running under software control and a plurality of network controllers, all coupled together via a controller area network (CAN) bus. Electronic control messages for controlling machine elements are sent among the computers and controllers using a novel message protocol to enable both broadcast messages and individual messages to be employed.
1. An improved top opening pocket for an insert machine wherein said machine has a conveyor with a plurality of pockets attached to said conveyor and feeders positioned along said conveyor for feeding flat material into a moving open pocket, the improved pocket comprising:
a leading wall,
a trailing wall and
a bottom wall which connects said leading wall to said trailing wall to define the bottom of a pocket between the leading wall and trailing wall, and two or more ridges in the bottom wall which run parallel with a long axis of the bottom wall, wherein at least one ridge is extending upward on the bottom wall and operative to help catch and maintain the position of the spine of a jacket introduced into the pocket.
2. The improved pocket of claim 1 , wherein said ridges extend along the entire length of said bottom wall.
3. The improved pocket of claim 1 , wherein there are three ridges.
4. The improved pocket of claim 1 , wherein each of said ridges are formed by a line of bumps in said bottom wall.
5. An improved top opening pocket for an insert machine wherein said machine has a conveyor with a plurality of pockets attached to said conveyor and feeders positioned along said conveyor for feeding flat material into a moving open pocket, the improved pocket comprising:
a leading wall,
a trailing wall and
a bottom wall which connects the leading wall to the trailing wall to define the bottom of a pocket between the leading wall and trailing wall, said bottom wall forming a substantially right angle with said leading wall, and including at least one ridge in the bottom wall extending upward on the bottom wall operative to help catch and maintain the position of the spine of a jacket introduced into the pocket.
6. The improved pocket of claim 5 , wherein said bottom wall is integral with said leading wall and said trailing wall is movably attached to said bottom wall.
7. The improved pocket of claim 5 , wherein said leading wall is integral with said conveyor and said trailing wall moves relative to said conveyor.
8. An improved top opening pocket for an insert machine wherein said machine has an endless conveyor with a plurality of pockets attached to said conveyor and feeders positioned along said conveyor for feeding flat material in an opening moving pocket and said pocket returns inverted, the improvement comprising:
said pocket having a leading wall, a trailing wall, a side wall is integral with said leading wall, and a bottom wall connecting the leading wall to the trailing wall to define the pocket, said trailing wall being spring biased against said leading wall;
a latch affixed to said side wall of said pocket, said latch having two positions, a first position where said latch is inactivated and said back wall of said pocket is movable into an open and closed position to accept flat products from said feeders when said pocket is in an upward position, and a second position where said latch is activated to hold open said pocket when said pocket is returned in an inverted position.
