Title: Apparatus for handling articles
IPC: A23L3/10
Filed: 1971-04-19
Abstract: 1353132 Transferring articles between conveyers; removing contents of receptacles; load handling H J HEINZ CO 19 April 1971 [30 Jan 1970] 20669/71 Headings B8A B8C and B8H Metal cans, steel shells, or other articles C deposited on a multi-lane conveyer 115 are controlled in transfer to a single lane conveyer 7a by the interaction of a gate 126 and an article positioning member 130. When the gate 126 is in its lowered position (Fig. 13), articles C can proceed from the lanes of the conveyer 115 (defined by adjustable guide plates 122) on to the conveyer 7a. The member 130 has scallopshaped recesses for positioning respective articles and holding them from movement on the conveyer 7a until each of microswitches 132 (wired in series) is contacted by an article. A drive cylinder 150 is thereby energized to retract the member 130 (see dot-dash position of its mounting bracket 133). A cam surface 153 connected to the operating linkage between the member 130 and the cylinder 150, thereby lifts a follower connected to linkage 166 carrying the gate 126. This prevents on-flow from the conveyer 115 while the articles C are proceeding on the conveyer 7a. Delivery of articles to the conveyer 115.- Containers carrying layers of articles C are permitted on retraction of a stop 16 (Fig. 1) to run by gravity on to spaced conveyer chains 9. A stop 26 locates the container correctly in position above a lifting head 40. The latter is elevated by an hydraulic cylinder 42 to a position in which the top layer of articles are engaged by a magnetic head 3 mounted on a wheeled carriage X. The head 40 is then lowered by a distance less than the height of one row of articles, and the carriage X is propelled by the action of a cylinder 85 (Fig. 2) to a position over the upstream end of the conveyer 115. A pneumatic cylinder 101 effects release of the articles on to the latter conveyer. The carriage X is prevented from moving into position over the. conveyer 115 if articles on the latter have backed up beyond a photo-electric gate 121-121a. When the carriage X has been returned to its original position above the head 40, the latter is lifted again and the same sequence of operations is repeated until the container has been emptied. Stops 26 and 29 then permit the container to be discharged to a position B<SP>3</SP>. The control of the lifting head 40 is monitored by a series of switches (59), (60), (63), (65), (72), (Fig. 14, not shown) operated by a rotary member 44 driven by a chain 45 connected to the head 40.

Abstract: 155,625. Spoelstra, W. Sept. 2, 1919. Continuous-discharge apparatus. - A machine for drying vegetables, fruit, and other materials consists of a series of tilting shelves arranged in the space between the walls of two vertical coaxial cylindrical tanks, hot air being supplied to the shelves by way of the central tank, and the vegetables are dried as they pass from one layer of shelves to another. As shown in Fig. 1, the outer tank 1 is supported by, and revolves upon, a circular rail 15, and is closed at the top by a cover 17 having a chimney 18 and an inlet closed by a rotating shutter 21. This shutter admits material but prevents the escape of hot air. The inner tank 2 is closed at the top, and at the bottom is connected to a tube 26 for supplying hot air. Openings 27, the size of which can be regulated, allow the hot air to pass into the spaces between the shelves. The shelves 3 - - 7 for supplying the material are each composed of sectorshaped plates 8 rotatable on axles which are journaled in the tank walls, the outer end of each axle having an arm 12, Fig. 4, which is pressed against a stop 13 on the tank by a spring 11 when the plate 8 is horizontal. Vertical bars 28, 32 fixed at places around the tank carry stops 33 which lie in the paths of the arms 12, so that the stops strike the arms and rotate the axles of the plate 8, thus turning the plates into a vertica position. In use, the material to be dried is fed by the shutter 21 on to the top shelf 3 and is submitted to the drying-action of upward current of hot air while being carried around the axis of the tanks. The sectors of the shelf are turned in succession by a stop 33, thus dumping its load of material on to the shelf beneath. Thus the material passes from shelf to shelf while being exposed to hot air entering through the openings 27 and finally leaves the machine through a rotating shutter.
