The present disclosure provides a sheet storage apparatus and a sheet processing apparatus capable of effectively reducing tension applied to the entrance portion of a storage bag that stores sheets at the time of sealing the storage bag. The sheet storage apparatus according to the present disclosure includes a sealing unit that seals a predetermined portion of the storage bag storing sheets and a tension reducing unit that reduces the tension applied to the predetermined portion.

A blister pack includes a housing having a plurality of cavities and a cover sealed to the housing and enclosing the cavities. The cover includes a base layer, at least one security element, and a heat protection layer. The heat protection layer includes one of an amorphous polymer and a semi-crystalline polymer.

A vertical bag-making/filling/packaging machine (1) comprises: a film supplying portion (5) which lets out a film (F) from a roll (Fr); a bag-making guide (31) which folds the film (F) into a tubular shape and changes a conveying direction downward; a vertical sealing portion (60) which thermally seals side edges of the film (F) to each other in an up-down direction so as to make the film into a tubular shape; a film conveying portion (50) which conveys the film (F) downward; a filling portion (70) which loads a content (X) into an interior of the film (F); a lateral sealing portion (80) which thermally seals the film (F) in a left-right direction so as to make a bag body; a square-bottom sealing portion (90) which expands a bottom of the bag body to a rectangular shape from an inside and then thermally seals the bottom to form a rectangular bottom surface; and a cutter (89) which cuts off the bag body from the film (F).

A poly bubble bag filling machine, seal head, bag magazine, and a carton are described. The filling machine includes the bag magazine which is configured to hold and advance a plurality of pre-formed poly bubble bags as they are retrieved for filling. The carton provides simple handling and replacement of bags in the magazine and enables operation of the magazine while the carton is in place. A bag-transfer carriage transfers bags from the magazine to the seal head. The seal head includes suction bars configured to enable application and retention of a sufficient suction force to sides of the bag to open and retain the bag during filling. Sealing bars are positioned near the suction bars and are operable to seal the bag closed via application of heat.

A heat seal device for use in a bag making apparatus includes: a first heat seal member; a second heat seal member facing the first heat seal member; a heater for heating at least one of the first heat seal member or the second heat seal member; a drive mechanism configured to move the first heat seal member towards and away from the second heat seal member so as to releasably sandwich a web between the first and second heat seal members; a sensor disposed to detect acceleration of the first heat seal member; and a measurement part configured to measure a sandwiching time during which the web is sandwiched by the first and second heat seal members based on data from the sensor.

A device (10) for sealing three-dimensional objects (16) in the bag opening (14) of a film bag (12) comprises a clamp (36, 38) for the film bag (12), which has a pair of clamping shoes (42, 44) on each side, between which the edge of the film bag (12) is held. A heat sealer (26, 28) is provided for sealing the three-dimensional object (16) in the bag opening (14) of the film bag (12), wherein the heat sealer (26, 28) has a pair of sealing jaws (26, 28) between which the bag opening (14) of the film bag (12) can be sealed. The two clamping shoe pairs (42, 44) of the clamp (36, 38) are moved apart from one another during the sealing process.

The present invention relates to a method and to a system for calibrating an automatic pouch forming machine.

The present invention also relates to a device for characterizing a pouch precursor made of flexible heat-sealable film, said device comprising: a punch; a heat source for heating at least a tip of the punch to a given temperature; an actuator for pressing the punch against the pouch precursor made of heat-sealable film, with a given pressure; a measurement device for measuring the penetration of the punch in the pouch precursor, under the given conditions of temperature and pressure.

A rotary to linear actuator, comprises a drive crankarm that rotates in a first axis of rotation; a first and second gearset connected to the drive crankarm through a second crankarm; and a piston captured between the first gearset and the second gear set, wherein the first and second gearsets rotate a crankarm connected to one end of the piston, wherein the piston is caused to move linearly upon rotation of the crankarm.

The present invention relates to a film wrapping machine for a product packing device using a stretch film, including a frame having vertical bars extending upward and spaced apart from each other, a film clamping unit including a pair of suction pads which are moved in a direction of being spaced apart from each other in a state of adsorbing the stretch film so that a front end portion of the stretch film supplied from a film supply device is opened, and a plurality of clamps configured to grip the front end portion of the stretch film opened by the suction pads, receive the stretch film whose upper end is cut and bonded by the film supply device in a wrinkled state, and process the stretch film to be covered on a product in a process of lowering the vertical bars, and a controller which controls operation of the film clamping unit and the film supply device.
