A quantitative material supply mechanism: an accommodation bucket, a delivery device, an adjustment device, and a quantitative feeding bucket. The accommodation bucket includes an outlet defined on a bottom thereof. The delivery device includes a conveyor belt, a drive roller, a driven roller, and a driving unit. The driving unit is connected with the drive roller and drives the drive roller to rotate, and the drive roller matches with the driven roller to actuate the conveyor belt to rotate. The adjustment device is arranged above the conveyor belt and is located between the accommodation bucket and the turnaround portion. The adjustment device includes two adjusters and two actuation units opposite to the two adjusters respectively. The quantitative feeding bucket is mounted below the turnaround portion of the conveyor belt so as to hold the materials which are delivered by the conveyor belt and drop from the turnaround portion.

A first sensor combined to a first storage carrier for the material for detecting vibrations associated with offloading the material and a second sensor for measuring the weight of the material expelled from the first storage carrier.

A product inspection apparatus includes a conveyor system for transporting items. The conveyor system includes a weigh conveyor with a load detector for detecting the weight of items transported on the conveyor system and a transport conveyor adjacent the weigh conveyor. The apparatus also includes a support structure with a support beam. The transport conveyor is mounted to the support beam by at least one support column externally mounted to the support beam such that vibrations are suppressed by the at least one externally mounted support column.

A device and method for the non-formatted weighing of a group of products. The products rest either on a positioning surface or on a supporting surface and, due to the relative movement of the two surfaces with respect to one another, are transferred from one surface to the other surface. By the acquisition of the weight of at least one of the two surfaces, the weight of each individual product can be determined.

Disclosed is a weighing conveying apparatus for goods, having at least one conveyor belt, and a weighing belt arranged downstream of the conveyor belt in the conveying direction, wherein the respective conveyor belt includes a belt body having an upper side and a transport belt running around the belt body in operation of the weighing conveying apparatus, and wherein the at least one conveyor belt is provided with a respective alignment rail at both sides in the conveying direction, with the two alignment rails serving for the alignment of the goods. The width of the respective transport belt is smaller than the spacing of the two alignment rails from one another, with the respective transport belt being arranged between the two alignment rails, and with the upper edge of the upper run of the respective transport belt being arranged above the lower edges of the alignment rails.

The automatic calibration device for integrating conveyor belt scales (100) is incorporated to a mounted-type integrating conveyor belt scale, mounted to bulk material conveyors, featuring a structure that supports racks with rolled cylinders, which, when assembled, are able to support the conveyor belt; the automatic calibration device (100) with the movement mechanism, comprised in this implementation, by a pair of parallelograms comprised of the beams (1) and (2) connected by rotating joints (7), (8), (9), (10) to the minor arms, (22), (23), (24), (25) which, in turn, are connected to the parallel shafts (3) and (4), with the distances between centers being equal to the distance between rotating joints of the beams; an actuator (14) is used to move standard weights (11) and (12), initially supported onto cavities (16), (17), (18) and (19) provided on the beams (1) and (2) of the parallelograms, until reaching the berths (30), (31), (32) and (33) connected to the weigh bridge (41) of the scale.

In a dynamic scale for flat goods on their sides, and a control method therefor, flat goods are transported with a continuous counting of encoder pulses, and a weight measurement of a moving flat good is started when the trailing edge of the flat good has reached a first sensor. A first count state of the counter is stored when the leading edge of the flat good reaches a second sensor but a valid weight measurement result is not present. A weight measurement takes place with a transport velocity reduced in steps. After a step-down of the transport velocity of the flat good a subsequent weight measurement is performed with a next lowest transport velocity, and the current counter state is then queried if neither a valid weight measurement result exists, nor can it be established that the trailing edge of the flat good has reached the first sensor, although the leading edge of that flat good has reached the second sensor, as well as a check shows the current counter state corresponds to the sum of the stored counter state and a predetermined count value. The querying steps after the check are repeated as long as the current counter state has not yet reached the sum, and with an additional step-down of the transport velocity of the flat good and weight measurement result, until the check shows the current counter state has reached the sum.

An article inspection apparatus includes a measuring unit 11 that outputs a measuring signal of weight within a required measurement time from a weight application time, when the weight of an article W is applied, a determination unit 16 that inspects the article W based on the measuring signal, an electromagnetic coil 84 that applies a diagnostic load to the measuring unit 11, and a performance diagnosis unit 18 that causes the diagnostic load to be applied from the electromagnetic coil 84 to the measuring unit 11, within a predetermined diagnosable time longer than the required measurement time from the weight application time, when the weight of the article W is applied to the measuring unit 11, and diagnoses the performance of the measuring unit 11, based on the measuring signal when the diagnostic load is applied.

A first sensor combined to a first storage carrier for the material for detecting vibrations associated with offloading the material and a second sensor for measuring the weight of the material expelled from the first storage carrier.

In an embodiment, the present invention provides a weighing and labeling conveyor for labeling articles, the articles including a first application point at a same point on the article, the conveyor including: a weighing conveyor for determining the weight of the articles; a transport apparatus for transporting the articles; and a labeling system for labeling the articles, the labeling system including three labelers, each labeler including an applicator, each applicator being suitable for applying a label to the first application point on an article while the article is being transported on the transport apparatus. Of the three labelers, during normal operation two labelers are in an active operating state and one labeler is in a passive operating state. During normal operation, the two labelers that are in the active operating state alternately label the first application point of successive articles.
