摘要:
An apparatus for cutting off lengths of slide fasteners from a continuous chain thereof includes a cutting punch coactive with an anvil, there being feed rolls disposed in the path of movement of the fastener chain upstream from the cutting punch, and a pair of delivery rolls in such path downstream of the cutting punch. The upper delivery roll is arranged to reciprocate with the cutting punch and to engage the chain before the cutting punch does, and to continue to engage the chain until the cutting punch has been slightly retracted. Such retraction of the delivery roll facilitates feeding of the chain even though the leading end may be slightly curled.

Prior to the forming of bar material, without creating internal stresses, on transverse transport presses, bars are sub-divided into sections of equal volume, the end-pieces of each bar having to be discarded before further processing. To provide for the automatic and material-saving discarding of the end pieces, two light barriers are installed in the feed zone of the bars, the distance (a) between these light barriers being newly stored in a microprocessor as each bar is fed in, and this distance being converted, by calculation, to three further distances (b, c, d). By reference to these data, the microprocessor controls the discarding operation, with one, or at the most two, section lengths being discarded per bar, according to whether the interface between two successive bars is located in the central region of the section length in question, or in one of its two end-regions.

A bar end dropper for forging machines or the like is disclosed which automatically operates to reject blanks cut from the end of the piece of stock which are of unsatisfactory length and to adjust the feed when necessary to ensure that the ends of pieces of stock being fed into the machine are a sufficient distance from the shear plane of the cutter to ensure a clean cutting operation. As sequential pieces of stock are fed to the machine, they are positioned in the measuring position and the measuring carriage moves in to position a sensor a distance from the shear plane determined by the length of the stock. This automatically positions the sensor. The sensor operates to sense the passage of the rearward end of the stock and determines (1) if the portion of the stock extending past the shear plane is of insufficient length to produce a usable blank and operates controls to cause automatic rejection of such piece or (2) that the ends of the pieces of stock will be an insufficient distance from the shear plane to produce a clean cut. In the latter event, the sensing assembly initiates a short feed operation to locate the interface between the two ends of stock a sufficient distance from the shear plane to ensure a proper cut.

Each customer order has the form of an image band segment comprised of one or more image sections bearing respective images. The customer order image band segments together form an elongated image band. The image band is provided with order marks of different types, each image section of one customer order being provided with an order mark of one type, and each image section of the next customer order being provided with an order mark of another type, so that the order mark type changes from one customer order to the next on the image band. The changes of order mark type are detected using a detecting arrangement which is operative for generating control signals in dependence upon such detection. The operation of an order-sorting arrangement is controlled by applying the control signals thereto.

A control system is disclosed for a hot forging machine which is supplied with lengths of stock. The system provides automatic rejection of workpieces cut from the rearward end of one length of stock and the forward end of a subsequent length of stock. The system includes a sensor which laterally deflects the rearward end of a length of stock as such rearward end approaches a control point to produce a signal to reset the system. As the forward end of the subsequent length of stock passes the control point, a second signal is generated to actuate the stock movement measuring system. Stock movement is measured by a measuring roller which engages and is turned by the stock as it moves toward the cutter. The rotation of the measuring roller drives a pulse generator which supplies a signal to a counter. When a first predetermined number of pulses have been generated following the movement of the forward end of a length of stock past the control point, it is known that a first predetermined length has passed and rejection of workpieces is established. When a second predetermined number of pulses have been counted to indicate passage of a second predetermined length, the normal cutter operation is re-established to terminate rejection of workpieces.

A labeling machine, system, and method capable of accommodating offset printed label tapes or other label tapes having discontinuities between the individual labels of a repeat print pattern, with feeding and severing such in controlled fashion utilizing a printed indicia code and a two stage feeding and cutting cycle, while uniquely securing and advancing articles or containers to be labeled with novel equipment, both in a manner to allow extremely accurate and dependable label application and subsequent label verification on the article as well as label position checking, and with discharge means positively governing discharge of the labeled articles according to acceptability or non-acceptability.
摘要:
A first counter counts each cycle in which a segment of a strip of material to be cut is within a predetermined thickness range and stops the cutting apparatus after a selected number of cycles has occurred. A second counter is employed to count either all of the cycles of operation of the apparatus or only the cycles in which the segment being cut is within the predetermined thickness range.
摘要:
A vertically fed strip of material is cut into segments of selected lengths by a horizontally movable cutting blade. The thickness of the strip of material is measured so that the cut segment has its thickness measured during the feed portion of the previous cycle to that in which it is cut. If the thickness of the strip of material exceeds a predetermined thickness, the measured segment is diverted into another area after being cut during the next cycle.
