摘要:
An apparatus, a method and a system for cutting or trimming a portion of an article using a jet stream provided by a nozzle tip. The apparatus includes a drive unit configured to provide a rotational force and a cam assembly connectable to the drive unit and configured to move the nozzle tip to cut the portion of the article. The apparatus includes a conveyor belt that has a void area and a cutting area, and a cam that includes at least one track to drive a frame assembly.

A high-throughput, high-end-product-recovery, lineal log bucking device featuring continuous stem travel during the cutting process by using a simple and efficient machinery design for economy of equipment and monies. The apparatus includes: (1) a saw for cutting stem into logs; and (2) apparatus for accelerating the carrier up to the speed of the stem conveyor(s), maintaining the speed during the cut, decelerating the carrier, and then returning the carrier to its starting point.

A sheet finisher for an image forming apparatus of the present invention includes a conveying device for conveying a sheet and a punch unit for punching the sheet being conveyed by the conveying device. A sheet edge sensor senses the edge of the sheet, which is being conveyed by the conveying device, parallel to the direction of sheet conveyance. A drive source moves the sheet edge sensor in a direction perpendicular to the direction of sheet conveyance. Another drive source moves the punch unit in the direction perpendicular to the direction of sheet conveyance in accordance with information output from the sheet edge sensor. A controller controls the two drive sources by a preselected pulse ratio, thereby causing the punch unit to accurately punch the sheet.

An apparatus for feeding sheets comprises a variable speed conveyor for feeding a sheet cut from a web. A high speed conveyor receives the sheet fed by the variable speed conveyor, and feeds it at a high speed v1. A cutting completion detector detects the separation of the sheet from a cutter and generates a detection signal. A controller adjusts the feeding speed of the variable speed conveyor to a feed speed v2 as long as the leading portion of the web is being fed to the cutter, adjusts the feeding speed to a speed v0 (v0

An apparatus for producing a continuous succession of pieces or sheets, particularly suitable for infeeding cut pieces of wrapping material to wrapping machines, comprises a track for collating and sending forward the said sheets or cuttings; a plurality of auxiliary tracks leading to the said collation track; means for channelling along the auxiliary tracks, successively, wrapping material from respective reels; and control means for rhythmically cutting such material and for automatically feeding material, end to end, from a fresh reel on exhaustion of an empty reel. The control means comprise sensor means for detecting the end of the material from the empty reel; for cutting from the end portion a piece of material equal in length to or a multiple of the length of the said sheets or cuttings and for thereupon causing material to move forward along another of the said auxiliary tracks so that there is a continuous succession of sheets or cuttings along the above mentioned track where the said sheets or cuttings are collated and sent forward.

A rotary veneer clipper has a pair of cutting blades spaced 180.degree. apart on a rotary clipper shaft for cutting cooperation with a roller anvil below and parallel to the clipper shaft and over which sheet material passes. The clipper shaft rotates intermittently on signal to cause one of its blades to clip the sheet. The clipper shaft is driven by a pair of pneumatic drive cylinders mounted one to each of two crank arms connected to a common drive shaft. The cylinders stroke once simultaneously to rotate the drive shaft alternately in opposite directions through 90.degree. upon each successive clip signal. When the drive shaft rotates in one direction, a first gear train transmits power from the drive shaft through a first one-way clutch to the clipper shaft to rotate one of the blades downwardly and through 180.degree. to clip the sheet. When the drive shaft is rotated in the opposite direction, a second gear train transmits power from the drive shaft to the clipper shaft through a second one-way clutch to rotate the other clipper blade through 180.degree. in the direction of sheet travel to clip the sheet. Locking means including a pneumatic locking cylinder limits clipper shaft rotation to exactly 180.degree. upon each stroking of the drive cylinders to accurately index the cutting blades. An optional blade speed control feature is also provided.
摘要:
The present apparatus comprises a sliding carriage placed on a guide extending in parallel with a tube to be cut, said carriage supporting a cutting device and a means making the same fixed with the tube under a control order applied thereto through a detector detecting the distance of which the tube has been advanced.

Presented is an automatic cutoff machine for cutting to length strip material as it is discharged in a continuous length from an automatic machine. The cutoff mechanism includes sensing means adjustable to sense a predetermined length of strip and operable to activate a cutoff saw to cut the strip to the predetermined length. Because the strip being cut is moving, the cutoff mechanism must also move with the strip and at the same rate to preclude binding between the cutoff saw and the strip being cut.
摘要:
A continuously traveling plastic extrusion passes in line through a cut-off and/or tooling unit mounted on a carriage which travels a limited stroke at the same speed as the extrusion, during which a tooling operation is performed on the extrusion, whereupon the carriage returns to its initial position. Such operation of the tooling is optionally triggered and timed by any one of: (a) a metering wheel which rolls on the advancing extrusion and has a circumference substantially equalling an extrusion length to be cut off and/or tool-formed, the wheel periodically cam-operating a control microswitch; or (b) an end gauging control microswitch which is periodically operated for a limited interval by an extrusion passing through the press; or (c) a photoelectric control switch which is tripped for a limited time by the traveling extrusion interrupting the photoelectric cell beam. The mechanical operations of the tooling unit and carriage are controlled by solenoid controlled valve and cylinder means; and a tooled extrusion piece is automatically discharged from the equipment by synchronized fluid pressure-operated dump means.

A rotary cutter for use in an apparatus for the inspection and removal of defects from strip-like articles in which the cutter is a rotary driven member having a plurality of slots containing blade members which are capable of movement between a retracted position and a cutting position and are activated to a cutting position in response to signals from an inspection device.
