Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for selectively testing the weight of typefaces being moved in a stream.

A suitable example of such an object is that it is moved in r rows l at a predetermined distance from each other in an automatic boxing machine equipped with a collection device, and is set within a strict tolerance range by the collection device. There is a container loaded with an amount of product having a weight close to its weight.

Collection devices are sometimes used that are volume-deaf, and the density of the product to be boxed delivered to the device varies over time, sometimes resulting in wide density deviations. Taking this situation into account, current methods are currently being used to detect differences in the density of products being sent at predetermined intervals.
A boxing machine is used that is configured to adjust the containers for collection #c in accordance with this. In this sense, containers containing electronic key products m that are quite close to the set weight can be effectively delivered from the boxing machine.On the other hand, the standards and regulations that affect this industry are based on actual vAVc valley equipment. 3A' Confirmation of packed product lid.
The opinion that M should be used is becoming more and more popular.

This confirmation consists of indirect procedures and sampling inspections, i.e., one side after loading located at set intervals in the flow to the packing house.
This can be done by weighing the container. Using a similar systematic verification procedure, it is also possible to statistically check the packaging condition and, if necessary, to indicate which products in the container should be excluded because they are outside the tolerance limits.

In fact, an inspection method has already been implemented in which the weight of loaded containers is occasionally measured outside the packing road, but this inspection only involves workers transferring the loaded containers to a table-shaped weighing device. , the weighing scale is located outside the boxing path and has no connection with the operating cycle of the boxing machine.

On the other hand, there are also continuous conveyor weighing devices in which the conveyor has a closed-loop telescopic configuration. Metering devices of this type are manufactured by Optima Machinenfuaprik, Schwabish Hall, West Germany, and Hi-Speed Zückweyer, Ithaca, New York, USA. The conveyors of these weighing devices receive the objects to be weighed and move them in a stream; the objects are in fact weighed as they travel. The conveyor therefore comprises a travel path section on which the objects are arranged to move.

A specific VC is that the object metered in a continuous conveyor cap system often takes the form of a layer of material that is deposited at a given time on a conveyor and part of a continuous material stream. In that case, the metering device typically performs two meterings per revolution of the continuous conveyor. On the other hand, when weighing equally spaced objects moving in a line, the presence of the weighing device severely limits the throughput of the machine, such as a cartoning machine, through which the objects are delivered.

A principal object of the present invention is to deliver individual objects in a row to a continuous conveyor needle metering device disposed along the path of movement of the object row for a desired time □ without interrupting or delaying the flow of objects. The object of the present invention is to provide a pair 'M for incorporating an additional device capable of inspecting the needle amounting device 91ii, thereby making it possible to arbitrarily select the interval between objects to be sequentially inspected over a wide range.

Another object of the invention is to provide such a device which has a very high flexibility of use with respect to variations in object flow, forward speed and distance between objects.

The purpose is to provide a device for selectively checking the weight of moving objects in a row along the flow path of said moving objects in cooperation with a continuous conveyor type weighing device placed in a part of said flow path. Conveyance rollers driven at the same circumferential speed as the conveyor of the weighing device are disposed along the same conveyor in the flow path section, and these conveyance rollers are moved from a working position above the conveyor where they receive and move the object. The conveyor is attached to the weighing device so as to be movable to a non-working position below the conveyor that moves the object, and can be sequentially controlled to take and maintain the non-working position and then return to the working position. Objects are placed one by one on the conveyor of the weighing device and weighed during their movement along the same conveyor, during which time a part of the object on the conveyor becomes increasingly inactive below an object. This is achieved by the apparatus of the invention, characterized in that the transport rollers of #1 are slightly larger than object #1 and define a box member that advances in relation to the object.

Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

In the V-plane, the object whose weight is to be selectively checked using the device 1 according to the invention is a box-shaped container, referenced 2. These containers 2 may have a wide range of dimensions, with a small container 21 shown in FIG. 2 and a large container 2b shown in FIGS. 3 and 4. The container 2 is stored in a collection device (b) of an automatic box packing machine (not shown).
After being packed with a certain amount of product by the attaching device, it is sent out from this machine. That is, from the above-mentioned boxing machine, identical containers 2 are continuously fed in one row at regular intervals in the direction of the arrow M, except that the vertical walls of each container 2 are in the same direction B in the front-back direction. Both are in the m-plane. 4
is a conveyor belt disposed to receive the containers 2, which is fixed to a horizontal rotating shaft 6 and is moved by a drive roller 5, and the circumferential speed at this time is such that the distance between the containers 2 is increased compared to that in history. Therefore, the speed is set higher than the delivery speed of container 2 from the r+11W boxing machine. T is a belt located above the conveyor belt 4, and is driven by a drive roller 8 fixed to a rotating shaft 9. The bottom of this bell) 7 is the conveyor bell)
401 parts, effectively pressing against the top surface of the container 2, thereby ensuring a secure sealing of the glued and folded lid part. '''10 is the rotating shaft 9 and the bell) 7
is a longitudinal beam supporting the shaft of the other roller with which it engages, and is guided so as to be slidable along the column 11 and held at a desired height [Figure 2 shows the beam 10 in the raised position. show〕. Therefore, the distance between the adjacent parts of both bells) 4.7 can be adjusted depending on the height of the container 2. The rotating shafts 6.9 are each driven away from the vertical shaft 13 via bevel gear pairs 14-14b and 15-15b. This vertical shaft 13 is connected to the beam member 1
In order to enable the vertical movement of the bevel gear 15b and the box 16 that rotatably supports the bevel gear 15b, the umbrella is slidably inserted through the bevel gear 15b and a box 16 that rotatably supports the bevel gear 15b, and is provided with a key that slides next to and inside the vertical shaft 13. Gear l5kl is always engaged.

The device 111 is provided between the conveyor belt 4 on the supply side and the conveyor belt 1T on the discharge side. The upper part of the conveyor belt 1T coincides with the upper part of the conveyor belt 4 in the same plane and has the same running speed. conveyor belt 1
7 is driven by a roller (not shown) connected to the power system of the box packing machine, and is also driven by a roller 18 fixed to a rotating shaft 19 near the device 1.

Between these rollers 18 and the vertical shafts 13 transmitting the motion to the belts 4, 7, a kinematic linkage is provided which ensures the same circumferential speed of the bells 17.4.7.

That is, a sprocket 20 is fixed to one end of the rotating shaft 19, and a chain 21 is wound around the sprocket 20.
The sprockets 22 and 23 drive the sprocket 24 fixed to the rotating shaft 25. The rotating shaft 25 further includes a sprocket 28 for a chain 21 attached to the shaft 29, as will be described later.
is fixed. The device 1 cooperates with a conventional continuous conveyor needle metering device 30 manufactured by the German and American companies mentioned above. The continuous conveyor of this weighing device 3o consists of a set of belts 31, which are wound around driven rollers 32 and drive rollers 33 fixed to shafts 34,35. The shaft 34 , 35 is rotatably supported between two longitudinal beams 36 forming the upper end of the weighing device moving mechanism 37 . One shaft 35 is driven by a variable speed motor unit 38 whose main body is supported by one spar 36.
The motor unit 38 is configured to transmit a speed to the belt 31 equal to the circumferential speed of the belt 4.17. It is well organized. The upper part of the belt 31 always moves upward, is supported by a strip 39 between both girders 36, and is attached above projections (2) extending from the girders 36 at equal intervals. The weighing device moving mechanism 31 is attached above the base 42 and has a total of one
It is supported by a case 41 that constitutes a fixed part of the device 30. As will be explained below, the device 1 coordinates the operation of the metering device 30. That is, while determining which container is to be weighed, only one of the containers is placed on the needle electric device U30 each time, giving the weighing device 30 a sufficient amount of freedom in weighing time. The metering is produced by an electromechanical position transducer built into the meter Jt*d3G. That is,
The over-amplified signals from the position transducer are proportional to the deviation between the actual weight of the container under test and a predetermined reference weight, and these amplified signals are sent to an electronic processing unit for processing. , recorded and/or displayed, and performs corrective actions on the simultaneous VC automatic collection device.

Note that even before weight measurement, the weighing device 30 described in 1. may be affected by an intermediate lid shift of the moving mechanism 31 due to, for example, accumulation of dust on the moving mechanism 31 or falling of dust from the mechanism 37. To eliminate the influence on the measurement, the tare can be measured.

When the position of the base 42 is set to 1, In in this way, the longitudinal axis C-G on the center line of the belt 31 and the roller 43 is fed so that the force direction f and KB of the wall 3 coincide with each other as described above. The horizontal dimension is made to coincide with the center line of the movement path of the container 2, which varies depending on the size.

Now, each roller 431L...43m solenoid valve 6
As will be described later, V-coil 1 is closed when an appropriate fan-shaped member T3 faces each proximity sensor 74...7411.
” He will control you. This fan-shaped member 13 is removably attached to the end of the shaft 29 opposite to the sprocket 28, and is disposed within the air conditioning section T5, which can be accessed by removing the cover lt (not shown). Therefore, the fan-shaped member 13 has a length of 8 m.
, which is particularly suitable for the dimensions of the containers 2 being processed in the cartoning machine, is fixed to the shaft 2@. For example, for container 2&, fan-shaped member 73& (FIG. 2) corresponds to container 2b.
The fan-shaped member 73b (FIGS. 6 and 7) corresponds to this. The sensors 74 &...741m are disposed at the bottom of the cavity 75, and in this embodiment, they are arranged at 1800 angles and at the same time, in the same order, around the axis of the shaft 29, concentrically with the coaxial line. They are provided alternately and regularly on two circular arcs. A proximity sensor 76 is further provided at the bottom of the cavity 75 on the inner side of the two arcs and on the line between the two arcs, the function of which will be described later. Fan-shaped member 1
3 has a home position corresponding to a portion of the cavity T5 where no sensor exists. When rotation is transmitted from the sprocket 28 to the shaft 29 in the direction shown by the arrow, the fan-shaped member 1
3 acts on the sensors 74 and 76 sequentially.

The sprocket 28 (FIGS. 5 and 6) is attached to the shaft 29 by means of a freewheel coupling device IT, which engages after adjustment by a sagging device 78. That is, this coupling device 77
In a well-known manner, the outer cylinder 7 is equipped with the Sugrocket 28.
9 and a force cylinder 80 keyed to the shaft 29, a friction contact roller 81 is interposed between the outer cylinder 79 and the inner cylinder 80, and a cam with teeth 82 & is provided on the guide holder of the roller 81. 82 is formed on the periphery, and an arc-shaped 1llll12b is formed on the front surface.
A ring with is fixed. This n1182 b
In K, a pin 83 fixed to a seven-ring member 84 coupled to the inner cylinder 80 engages, and a coil spring (not shown) that acts in a torque manner is interposed between the cam 82 and the seven-ring member 84. It is inserted. The teeth 82 & of the cam 82 are the pawl device t.
The lever 85 is normally locked by a pawl 85 formed at one end of the lever 85, and the lever 85 is pivoted Q6) and urged in the direction of engagement with the cam 82 by a spring BT. When energized, the electromagnet 88 acts on the other end of the lever 85 and releases the pawl 851 from the teeth 112 (FIG. 6), thereby bringing the coupling device 77 into engagement and thus allowing the sector 13 to rotate. shall be. As will be described later, the weight of the container 20 is inspected while the scale 30d sector member 73 is rotating, and the electromagnet 8
8 is deenergized before the fan-shaped member 13 completes one rotation, so that the pawl SSt again engages the teeth 82 at the same time as the completion of one rotation.
1, the coupling device T7 is disengaged, and the sector gear 73 stops at the home position to prepare for the next rotation. Here, the electromagnet 8B can be energized in various ways. For example, if it is energized under the control of a cam that follows each cycle of the boxing machine at a constant rate, the electromagnet 8B can be energized for each of the many containers 2 processed in one boxing cycle. The relationship is such that only one item is inspected. Furthermore, by carrying out the above-mentioned energization under the control of a timer, it is also possible to configure one container to be inspected every time a very long period of time has elapsed. In any case, the electromagnet 88 is energized in the appropriate phase described below.

Furthermore, there is a definite ratio between the angular velocity of the sector 730 and the circumferential velocity which is common to all belts 4, 17° belts 31 and rollers 43 and which advances the containers 2, i.e. one container 2 While the sector T3 moves through the angle between two adjacent sensors 4, it moves a distance equal to the distance between two adjacent rollers 43.

FIGS. 8a and 8b respectively show the fan-shaped member T3&.

It represents the number of containers (20) located simultaneously on the belt 31, and the distance between the containers 2. 1192, which is slightly longer than one fM 91, indicates the maximum number of rollers 43 that can be in the non-working position at the same time, and when expressed in angle, the related section 74
corresponds to the angular distance of the fan-shaped member T3 acting on the . Finally, -84, which is the difference between line 90 and one #91, is the part that can be used for measuring the total J1 load m30r in the path from roller 32 to roller 33 of one container 2. ,
In terms of angles, it corresponds to the angular distance of the inner ring 95 of the fan-shaped member T3 that acts on the sensor 76.

...6 (II is provided in parallel with each other between the two lead wires 96 and 97 forming the power supply line, and one end is directly connected to the lead wire 9fJVC.'' The proximity sensors 74m...741101 are connected to the lead wsrvc only via the associated switches defined, or in a more complex manner to the lead 9T.The very simple method described above is used in all cases. , whose switches are finally subjected to the action of the sector T3 (concerning the coil 6 (1 to 60 m) and therefore the sector T3
moves and sequentially acts on the switches 74g...7411 to close them, and the coils 60g...60 are immediately energized. The energization of the other coils 60&~60f can also be caused immediately by the closing of the respective switches 74&... Although only ~98f is shown,
It is necessary to arrange all the bridges 981L...98f vertically, and from this point the switches 74a...74
Connect the movable contact f to the lead wire g7vcl. Other ways of arranging the bridge include Ward 1 Middle, Bridge 981L...
・The 6" horizontal arrangement shown for 980iC is possible, in which case the pf moving contact of each switch passes through the 97V lead wire through a bridge, and the fixed contact of the next switch, that is, the sector member 73, closes next. Connected to the fixed contact of the switch.As will be explained later, it is used to obtain a fixed operating pattern.
A predetermined number of bridges are arranged horizontally, and the number of horizontally arranged bridges varies depending on the dimensions of the container 2.
f also has a 1st order horizontal arrangement from the bridge 981L.

In the case of the container 21, only the bridges 98 &... 98C are arranged horizontally, and the switches 74 &... 740 are arranged horizontally.
Even if the coils 1'+□1 are closed by 3, the coils 601L...600 are not energized. That is, horizontally arranged bridges 98 & 98 between the switches.
Since it is connected at 0, the coil BOIL...600
energization is delayed, and the fan-shaped member 73 is energized simultaneously with the energization of the coil 60d at the time when the switch 74 (1) is also closed.

Regarding deenergization, regardless of the arrangement of the bridge, all the coils 601...60111 are deenergized in the same way, that is, each switch 741L... by the fan-shaped member T31C.
・It will be released as soon as the action on 741m is completed.

Next, the operation will be briefly explained. Referring to FIG. 2, first, assuming that all the bridges 98...98f are arranged vertically and the switches 741L...74 are directly connected to the lead bridge 97 in all cases, the weight of the moving object is In the selective inspection method, when the electromagnet 8B is energized, the fan-shaped member 73 starts one rotation and acts on the sensor T4 and then on the sensor T4b, and the rollers 43 & 43b sequentially return to the non-working position. Descend to ゛. Then, the container 2, which is being sent in the direction of the arrow by the rollers 45 and 46, has already been lowered by the rollers 43&,
Roller 43. Since b is also descending, it faces belt jllc and begins to engage with them. When the fan-shaped member T3 further rotates, the other sensor T4 is also affected and the other loaf 43 is also affected. - As a result of being forced to the next F4, container 2 is completely V
It is sent to the C-belt 31 in shock. At the moment when the next container 2 appears on the belt 31, the sector 13 is already connected to the sensor 7.
41Lvc, and therefore the roller 43
Since the container 1L has already been returned to the working position, the second container 2 is supported by the rollers 43& and is always positioned above the belt 31. Then the fan-shaped member 7
3 acts on the new sensor 74 while the other sensor 74
Since the action on the container 4 is continuously stopped, there is a temporary non-working position 11 below the container 2 which is placed on the belt 31 and whose weight is being measured.
The line type 99 consists of one group of rollers 43.
is formed, and this box 89, together with the valley fS2 under measurement, [
The body curves. In Figure 2, the third valley 621L from the stone is being measured, and the fan-shaped section 73 is being measured by the sensor 74r...

...431 is formed. When the container 2 leaves the belt 31 after the measurement, the time of action of the sector 13 on the sensor ysic ends, and the metering device 30 can always carry out a lid measurement if necessary, and the next one of the sectors 73 It returns to the working state by rotation of . The container 2 is the belt 31
When moving outward, the action on the last sensor 74 also stops, so the last roller 43 is raised and the box 9B gradually disappears. Then, when the fan-shaped member 13 makes one more rotation after one rotation, the box 93 is moved again to the roller 43Lill.
emerging from and forming and advancing in the manner described above.

The device 1 thus disables the measuring operation of the weighing device 30 and itself transports the containers by means of rollers above the continuous conveyor of the weighing device. In the case of a vertical arrangement of the bridge S8, the device 1 carries the container onto the conveyor and weighs it from the moment the container appears at the inlet end of the conveyor. In this sense, the rollers are lowered one after the other below the conveyor, and when the entire container is on the conveyor, the number of rollers lowered at the same time reaches a maximum.

Therefore, the box 5sFi gradually appears, moves forward, and gradually disappears.

On the other hand, if the required number of bridges 98t are arranged horizontally,
A fully formed box 99 appears at one time, moves with the weighed container 2, and disappears when the container 2 moves out of the scale conveyor. In this case, the frontmost roller 43 with all the rollers in the raised position receives the container 2 to be weighed,
When the entire container 2 rides on the belt 31, it is rapidly lowered, and the container 2 is placed on the belt 31 to enable weighing.

Although the object of the present invention is achieved as described above, various modifications are possible without departing from the scope of the present invention.

Note that when implementing the present invention, the materials, shape, and dimensions used can be appropriately selected as necessary.
