The present invention discloses a bag packing mechanism for mushroom cultivation, which comprises two clamping seats, transport means, air duct, pumping means and push rod. Transport means supply collar. Air duct descends through the collar and extends into a bag from the opening of the bag, the two clamping seats clamp the top portion of the bag to close to the outer periphery of the air duct, the pumping means sucks the top portion, the two clamping seats open, the push rod is lowered to push down the collar to put on the top portion, the pumping means blow to open the top portion, the push rod is further lowered to fold the top portion down, the air duct and putter rise, and then complete the automation of packaging job.

A shrink sleeve apparatus is disclosed herein that includes a shrink sleeve applicator, a downstream heat shrink station, and a horizontal conveyor having side-by-side rollers that have a circumscribing outer portion with at least one high traction segment and at least one low traction segment. A method of applying a shrink sleeve to an article is disclosed that includes providing a conveyor having rollers as disclosed herein, positioning the rollers such that low traction segments of the rollers support the article as it passes a shrink sleeve applicator, which applies a shrink sleeve. The high traction segments of the rollers do not interfere with sleeve application. As the conveyor moves the article and sleeve through a downstream heat shrink zone, the rollers are rotated so that the high traction segments contact the article and sleeve to assure rotation of the article and sleeve during heat shrink.

An improved knockdown crate and method of display for sale thereof. The knockdown crate generally includes two end panels, each with a bottom edge and opposing side edges, each edge comprising an interior groove extending the length thereof; a bottom panel comprising a plurality of longitudinal slats and two transverse connection members connecting the plurality of longitudinal slats in parallel, the transverse connection members have a geometric cross section which seat with the interior grooves of the bottom edges of the two end panels; and two side panels each comprising a plurality of longitudinal slats and two transverse connection members connecting the plurality of longitudinal slats in parallel, the transverse connection members have a geometric cross section which seat with the interior grooves of the opposing side edges of the two end panels respectively.

Provided is a label fitting system which can, even if a container has a narrowed portion, appropriately fit a cylindrical label to the outer periphery of the container. A label fitting system is provided with a label arrangement mechanism which pushes down a cylindrical label having been supplied to a location above a cylindrical container and is disposed about the outer periphery of the cylindrical label. The label arrangement mechanism is provided with a vertically movable annular base and a plurality of legs extending downward from the base. The legs have elasticity which enables the legs to be displaced radially, and have lower ends coming into contact with the upper end of the cylindrical label. When the base descends, the lower ends of the legs push down the cylindrical label while descending along the outer peripheral surface of the cylindrical container.

Food preservation can include depositing dry ice and food within packaging. The packaging can include a flexible liner defining a wall aperture and an internal chamber. The internal chamber can receive the deposited dry ice and food and have an internal atmosphere. The packaging can include a check valve mounted to the flexible liner and covering the wall aperture. The check valve can be configured to occupy: (i) a closed state blocking fluid communication between the internal chamber and ambient via the wall aperture and (ii) an open state enabling fluid flow from the internal chamber, through the wall aperture, and into ambient.

A conveyor system is provided including a conveyor and a plurality of functional trays that are removably attachable to the conveyor. Each tray includes a plate having first and second dimensions that are orthogonal to each other, and the plate includes a coupler configured to be removably attached to the conveyor with the second dimension of the plate being in parallel with a moving direction of the conveyor. The plurality of functional trays include one or more of an envelope-opening mechanism, an item-pushing mechanism, an envelope-closing mechanism, an item-wrapping mechanism, and a tray-height-adjustment mechanism. For example, the item-pushing mechanism includes a pusher slidably coupled to the plate, and a linear actuator configured to move the pusher relative to the plate along the first dimension so as to push an item off the functional tray.
