Definitions
- ABSTRACT Tumble packing apparatus for filling a case with containers such as damageable, liquid-filled, lightweight plastic containers and the like including: apparatus for discharging containers in a free fall path of travel to a container case, and a cushioning pad which is selectively movable from a removed position into the path of initially charged, free falling containers to temporarily interrupt and cushion the free fall travel of the initial charge of containers before they impact the container case.
- Mechanism is provided to remove the pad, after a predetermined number of containers have been cushioned, to permit the initial charge of containers to move to a final position within'the case and cushion the immediately following containers which fall to fill the case.
- Tumble packing filled containers in cases typically involves moving a standard size dairy or fruit juice case beneath container discharge mechanism which releases free falling containers.
- dairy standards permit the use of flat-bottom cases for tumble packing, such cases are not practical in the dairy and fruit juice industries since such cases are not as quickly and economically cleaned.
- the cases utilized have side and bottom panels incorporating wire or plastic grids so that water, debris, and spilled container contents can be readily washed therethrough.
- Each of the grids or grills has protruding edges which constitute blunt knife edges and, when free falling containers strike such edges, the impact energy sometimes causes penetration of the containers and the closure members or cracking of the containers, resulting in what are known as leakers. It has been discovered that damage generally occurs to only the first few containers inasmuch as succeeding containers are protected because they land on the initial charge of deformable containers already lining the bottom of the case.
- frame support means comprising: frame support means; apparatus thereon for supporting an article case at a case filling station; conveying means on the frame support means for supplying a line of articles to a higher level than a case at the case filling station and releasing them in a free fall path of travel to the case; means on the frame support means movable in a to-and-fro path of travel between a removed position out of the path of the free falling articles, and an operative position in the path of the free falling articles for interrupting the free fall of at least a portion of them to prevent them from striking sharp edges on the case in their free fall path of travel; and means on the frame support means for moving the interrupting means in said to-and-fro path between the operative position and the removed position to permit the interrupted containers to finally settle in the case.

- the normally closed limit switch contacts LS-2a which are closed when a limit switch LS-2 downstream of the case filling station 24 is energized by a case moving away from the case filling station 24, and the normally open counter contacts CR2 which close when a predetermined number of containers have been deposited in the case' R to fill the case.
- the containers 0 are formed, filled, and sealed by apparatus such as that disclosed in United States patent application Ser. No. 154,058, filed June 17, 1971, and now U.S. Pat. No. 3,744,212 which is assigned to the assignee of the present invention.
- the conveyor chains 22 are driven to move a case R against the pivotal stop bar 26 extending into the path of a case R at the case filling station 24, and this activates limit switch LS-l.
- the contacts LS-la (line L4) close to energize the cushioning pad advance solenoid 68a to lower the cushioning pad 66 in a downwardly inclined path of travel into the container case R at the case filling station 24 to the position illustrated in FIG. 1.
- the contacts LS-lb (line L7) are closed to energize the brake retract solenoid 58 for retracting the brake 55 and permitting the star wheel assembly 40 to be freely driven by containers c moving on the conveyor 35.
- the filled containers 0 continue to flow into the container case Rutilizing the initial charge of containers c as a cushioning layer which now lines the bottom wall 68 of the container case R during the remainder of the filling operation for that particular case.
- the electronic counter CR When the case is filled with a predetermined number of filled containers c, the electronic counter CR will have been actuated a predetermined additional number of times so that the normally closed counter contacts CR3 (line L7) open to deenergize the brake solenoid which releases the brake 55 into engagement with the brake drum S4 and prevents the containers 0 from turning the star wheel assembly 40 and thus prohibits the further passage of containers 6 on the conveyor 35.
- the contacts CR2 (line L9) also close to energize the retract solenoid 30b (line L9) which retracts the pivotal case stop 26 to the solid line position illustrated in FIG.
- the container case R Upon exit from the case filling station 24, the container case R trips the limit switch LS-2 to open the limit switch contacts LS-2a (line L9) and deenergize the stop retract solenoid b. This closes the contacts 30b 1 (line L8) and permits the stop advance solenoid 30a to again be energized to laterally position the pivotal case stop 26 in the path of the next succeeding container case R moved to the container filling station 24.
- the electronic counter CR will have been reset and the cycle will again repeat itself when the limit switch LS-l is again actuated by a succeeding case R arriving at the case filling station 24.
