  • Patent number: 9919445
    Abstract: An apparatus for cutting food objects conveyed from an inlet conveyor to an adjacent outlet conveyor. A moving mechanism is operably connected to the outlet conveyor to provide movement of the inlet end of the outlet conveyor from an adjacent position. The inlet end of the outlet conveyor is moved from a position adjacent to the outlet end of the inlet conveyor to an open position and back to an adjacent position. A cutting device cuts the food objects into portions and trim. A control unit controls the moving mechanism to move the inlet end of the outlet conveyor to an open position when separating trim portions to fall as desired and subsequently instructs the inlet end the outlet conveyor to move back to the adjacent position before the next cutting to provide a support for the remaining parts of the food object.

  • Patent number: 8807322
    Abstract: An object transport apparatus comprises a transport conveyor. Objects are compelled to move through an object space adjacent to the transport conveyor. A plurality of flights is disposed along a variable path and constrained to move along that path. A variable portion of the path is disposed adjacent to the transport conveyor. The flights disposed along the adjacent portion occupy a portion of the object space of the transport conveyor. A first transfer element is disposed along the variable path. The motion of the first transfer element varies the length of the variable path adjacent to the transport conveyor. An object sensor is disposed to detect objects upstream of the transfer element in the object space of the transport element. A controller interacts with a transfer element drive to alter the position of the transfer element along the variable path according to the output of the sensor.

    Abstract: A dynamic temporary storing device for articles like syringes and similar articles is situated between an outlet of a first machine and an inlet of a second machine. In the dynamic temporary storing device, two pairs of side-by-side belts transfer articles from an outlet of said first machine downstream to an inlet section of an article conveying path. The articles are gathered, one after another, to form groups of articles in the inlet section. The conveying path ends with an article outlet section situated near the inlet of the second machine. Driving means are associated to the conveying path and pass at adjustable time intervals through the inlet section so as to pick up said groups of articles and move them along the conveying path up to the outlet section. Then the groups of articles are transferred them to the inlet of said second machine. Changes in operation rate of the second machine are compensated by changing the number of articles in each group or by changing the length of the conveying path.

Motors (43, 25) for the pusher tug conveyor (40, 41), for the belts (45) and for the transport unit (15) are controllable in phase, by means of a common processor (49).

  • Patent number: 6543767
    Abstract: A sheet product transfer device includes an elastic belt forming a continuous loop, the elastic belt having an inner surface, a first drive unit contacting the inner surface, a second drive unit spaced apart from the first drive unit and contacting the inner surface of the elastic belt, the second drive unit driving the elastic belt at a different surface speed than the first drive unit, and a plurality of sheet product grippers arranged on the elastic belt. Also disclosed is a method for transferring sheet products comprising gripping a sheet product with a gripper attached to a continuous elastic belt, decelerating the sheet product, and releasing the sheet product.

  • Publication number: 20030034225
    Abstract: A feed conveyor is operable in a first direction to deposit a stream of articles across a width of a downstream conveyor operating along a second direction, the second direction being at an angle to the first direction. The feed conveyor is an extendable conveyor that is accurately controlled for circulating speed, extension speed and retraction speed, to deposit articles transversely onto the downstream conveyor in a tightly spaced, grid pattern. The extension and retraction speed are controlled by a first servomotor and the conveying speed of the feed conveyor is controlled by a second servomotor.

  • Patent number: 6467608
    Abstract: In an adjustment zone (B), the spacings between objects, which are conveyed by independently movable holding elements (2) along a rail track (1) are e.g. for a processing operation adjusted to a predefined value larger than the minimum spacing. To achieve this, a continuously circulating and compressible, adjusting chain (5) running in a circulating track is provided, which adjusting chain (5) is elongatable in a controlled manner. The circulating track extends at least in the adjustment zone (B) parallel to the rail track (1) such that the adjusting chain is in engagement with holding elements (2) conveyed along the rail track (1). Furthermore, control means for adjusting a predefined compression of the adjusting chain (5) are provided in the adjustment zone (B). The adjusting chain (5) comprises e.g. chain links (6) joined together in an articulated manner. Assigned to every second articulated joint of chain links (6) are guide rollers (7.

  • Patent number: 6341685
    Abstract: An ordering device for arranging products received in the loose state in an orderly succession comprises a first and a second conveyor with belts defining a product feed path divided into active portions with variable lengths equaling complementary fractions of the total length of the path; a pair of transmission pulleys, respectively connected to the first and second conveyors to define the active portions and supported by a carriage which moves in both directions along the path; drive means designed to move the transmission pulleys so as to vary the length of the portions; compensator means for compensating the variations in the length of the active portions of the path with corresponding opposite variations in the length of the respective complementary sections of the belts; the device comprises one carriage and the compensator means comprise mechanisms equipped with rigid elements which are connected to one another and which connect the carriage and the belts and vary their geometric configuration accordi

  • Patent number: 6305525
    Abstract: A pressureless infeed conveyor table for forming a predetermined spacing between articles on a conveyor in order to create a uniform column for a packaging process comprises reciprocating carriages that are driven directly by a reversible servo-motor. By directly driving the carriages, the weight of the accompanying sprocket assembly is decreased and the speed at which the carriages move is increased to improve efficiency and processing time.
