  In the conventional weight sorting apparatus as described in Patent Document 1, the measuring unit and the sorting unit are configured separately, and these are installed adjacent to each other. There has been a problem that the dimension occupied by the apparatus becomes long.

  SUMMARY OF THE INVENTION An object of the present invention is to reduce the overall length of a machine by integrating a measuring unit and a sorting unit in a weight sorting device, and shortening the device occupation size in a factory production line.

  In addition, as described in detail in “Best Mode for Carrying Out the Invention”, as a specific configuration of a weight sorting apparatus in which a measurement unit and a sorting unit are integrated, in the present invention, weight is measured while conveying a weighing product. We propose a configuration that measures and discharges the weighing product being transported in a sorting direction different from that of the transport according to the measurement result. In such a configuration, a force in a different direction is applied to the weighing product being transported in a predetermined direction. Due to the functional necessity of discharging in different sorting directions, there is a possibility that an excessive load will be applied to the transporting means at the time of weighing and the weighing goods transported thereby.

  Therefore, the present invention has a compact integrated structure of the measuring unit and the sorting unit, and even if the weighing unit moving in the transport direction applies a force in a different sorting direction by the sorting unit and discharges in the same direction, Another object of the present invention is to provide a structure that does not cause an excessive mechanical load on the mechanism.

When the conveying means 6 moves in the sorting direction with respect to the weighing means 9, the elastic means 34 deforms in contact with the weighing means 9, and the force applied from the sorting means 14 to the conveying means 6. When the is released, the conveying means 6 is configured to return to the normal position by the elastic force of the elastic means 34.

The weight sorting apparatus 1 ′ according to claim 4 is the weight sorting apparatus 1 ′ according to claim 1 ,
The conveying means 6
When a force is applied from the sorting means 14 via the weighing product 5, the force rises in a plane inclined from a predetermined normal position and moves in the sorting direction.
When the force applied to the transport means 6 from the sorting means 14 is released, the screen is lowered by its own weight in an inclined plane and returned to the normal position.

According to the present invention, the weight is measured while transporting the weighing product 5 in the predetermined transport direction, and the NG weighing product 5 is placed in another sorting direction by the sorting means 14 based on the measurement result during the transport in the transport direction. The total time required for weight measurement and sorting can be shortened. In particular, according to the weight sorting apparatus 1, 1 ′ described in claim 1, when the weighing means 5 moving in the conveying direction is applied with a force by the sorting means 14 and discharged in the sorting direction, If the weighing product 5 having a large friction with the conveying means 6 or moved in the sorting direction is engaged with the conveying means 6, a force is applied from the sorting means 14 to the conveying means 6 via the weighing product 5. However, since the conveying means 6 can move in the sorting direction by receiving this force, there is no fear that an excessive load is mechanically applied to the mechanisms such as the conveying means 6 and the sorting means 14.

(1) Configuration of First Example As shown in FIGS. 1 to 3, the weight sorting apparatus 1 of this example has a measuring unit 4 having a base 3 supported on an installation surface by a support leg 2 as a main body. is doing.
On the upper surface side of the base 3, a conveying means 6 for conveying the weighing product 5 in a predetermined conveying direction is provided. The conveyance means 6 is attached with a plurality of conveyance rollers 7 (eight in this example) parallel to each other, and rotates in conjunction with a common frame 8 provided on the base 3 and these conveyance rollers 7. Details are provided with drive means (not shown).

  A weighing means 9 is installed at the center of the base 3, and the frame 8 on which a plurality of transport rollers 7 are mounted is attached to the weighing means 9.

  Then, the exit roller 10 (three in this example) is provided on the base 3 continuously on the discharge side of the conveying roller 7, and the weighed product 5 whose weight is measured while being conveyed is placed in the next stage. It is comprised so that it can send out to a process (apparatus).

The measuring unit 4 of the weight sorting apparatus 1 of the present example is a sorting unit that discharges the weighing product 5 whose weight has been measured and transported by the transport unit 6 in a different sorting direction during the transport according to the measurement result of the weight. Is integrated.
First, a pair of guide rails 11, 11 parallel to the axis of the transport roller 7 are spaced in the same manner as the width of the frame 8 in the base 3 below the frame 8 provided with eight transport rollers 7. It is fixed. A pair of moving bodies 12, 12 are movably attached to the pair of guide rails 11, 11, and the lower ends of the pair of moving bodies 12, 12 are connected to each other by a connecting member 13. The pair of moving bodies 12, 12 are inserted between the conveying rollers 7 on both sides of the frame 8 and protrude above the conveying surface of the conveying roller 7, and the upper ends thereof are arranged in the conveying direction of the conveying roller 7. A parallel sorting bar 14 is fixed.

  The length of the sorting bar 14 in the longitudinal direction is equal to the length of the six transport rollers 7 arranged in the transport direction, and the exit roller 10 in the frame 8 having the eight transport rollers 7. It is arranged near the end closer to.

  The sorting bar 14 is configured so that at least a part thereof exists at a position lower than the top of the weighing product above the conveyance surface of the weighing product 5 by the conveyance roller 7 so as to contact the weighing item being conveyed. ing. In addition, the sorting bar 14 is normally disposed at a position outside the transport range of the transport roller 7, but if the pair of connected moving bodies 12, 12 move along the guide rail 11, The sorting bar 14 can also reciprocate in the weighing direction of the weighing product 5 above the conveying roller 7 in the direction perpendicular to the conveying direction to push the weighed weighing item 5 in the sorting direction.

  Then, driving as a driving means provided with a rod extending in a direction parallel to the axis of the conveying roller 7 at a position substantially below the front surface of the base 3 of the weight sorting apparatus 1 and below the conveying roller 7. A cylinder 15 is attached. The tip of the rod of the drive cylinder 15 is attached to the connecting member 13, and the sorting bar 14 can be reciprocated as the drive cylinder 15 is driven.

  A discharge roller conveyor 16 is installed on the front side of the weight sorting device 1. The discharge roller conveyor 16 includes a plurality of carry-out rollers 17, the discharge direction of the weighing product 5 is orthogonal to the transfer direction by the transfer unit 6, and the transfer surface substantially coincides with the transfer surface of the transfer unit 6. ing.

  The control unit of the weight sorting apparatus 1 shown in FIG. 4 is installed in the vicinity of or separated from the weight sorting apparatus 1, processes the weighing signal from the weighing means 9, and controls the weighing product 5 being conveyed by the conveying means 6. The weight can be calculated, and it is determined whether or not the calculated weight value is within a predetermined allowable range, and the sorting bar 14 is operated as necessary. That is, if it is a non-defective product within the range, it is transported as it is by the transport means 6 and sent to the next step, and if it is an NG product outside the range, the sorting bar 14 is operated to eject the discharge roller from the transport means 6. It is sent to the conveyor 16 and discharged in the sorting direction.

Next, further features of the weight sorting apparatus 1 of this example will be described with reference to FIGS.
In the measurement unit 4, it has been described that the transport unit 6 is attached to the weighing unit 9. However, as illustrated in FIG. 6, the transport unit 6 and the weighing unit 9 are separate and the transport unit 6 is a weighing unit. It is attached to the means 9 so as to be movable within a predetermined range in the sorting direction.

  That is, with reference to FIGS. 5 and 6, the attachment structure of the conveying means 6 to the weighing means 9 will be described. First, the substrate 30 is placed between the pair of guide rails 11, 11 provided on the base 3. The weighing means 9 is installed on the substrate 30. A pair of slide rails 31, 31 are attached to the upper surface of the weighing means 9 in parallel with the axial direction of the transport roller 7.

  On the other hand, two sliders 32 are attached to the lower surface of the frame 8 having a plurality of conveying rollers 7 at positions corresponding to the two slide rails 31, 31, respectively. The frame 8 is configured to be movable in a sorting direction orthogonal to the conveying direction of the conveying means 6 by slidably engaging 32 with the corresponding slide rails 31.

  Further, a stopper member 33 made of an elastic member such as rubber is attached at a position downstream of the sorting direction substantially at the center of the lower surface of the frame 8, and a spring, a shock absorber or the like is positioned upstream of the sorting direction. A positioning return member 34 made of an elastic member having an elastic function is attached. The distance between the stopper member 33 and the positioning return member 34 in the sorting direction is substantially the same as the dimension of the weighing means 9 in the same direction, and the frame 8 is in a normal position where no external force is applied to the frame 8. The stopper member 33 contacts one side surface of the weighing means 9 on the downstream side in the sorting direction, and the positioning return member 34 is the weighing means on the downstream side in the sorting direction with substantially no deformation (deflection). 9 is in contact with the other side surface of the frame 9 so that the frame 8 is positioned relative to the weighing means 9.

  Then, as shown in FIG. 5B, when the frame 8 is in the normal position and the frame 8 is positioned with respect to the weighing means 9 by the stopper member 33 and the positioning return member 34, the frame 8 A gap t having a predetermined dimension is formed between the downstream end 35 in the sorting direction and the fixing member 36 of the base 3, and the frame 8 moves in the sorting direction by this gap t. It is configured to be able to.

(2) Operation of First Example Next, the operation of the above configuration will be described.
The weighing product 5 is put into the weight sorting apparatus 1 from the front stage (not shown). The weighing product 5 is conveyed by driving the conveyance roller 7, and when the weighing product 5 is placed on the conveyance roller 7 of the frame 8, the weight is measured by the weighing means 9. The weight measurement data is sent to the control unit 20, the weight of the weighing product 5 is calculated, and it is determined whether or not the measurement result is within an allowable range.

  If it is within the allowable range, the weighed product 5 (good product) is transported by the transport means 6 as it is, sent downstream, and then sent to an adjacent post process (not shown) via the exit roller 10.

  If it is outside the permissible range, the drive cylinder 15 is driven at an appropriate timing by a signal from the control unit 20 so that the sorting bar 14 moves downstream in the sorting direction and is carried by the carrying roller 7 of the frame 8. The finished weighing product 5 (defective product, NG product) is pushed out in the sorting direction, transferred onto the discharge roller conveyor 16 and discharged in the sorting direction.

  During the above sorting operation, when the sorting bar 14 applies force to the weighing product 5 moving along the transport roller 7 and tries to eject it in the sorting direction, the friction between the weighing product 5 and the transport roller 7 is reduced. When the weighing product 5 that is large or moved in the sorting direction is engaged with the gap between the conveying rollers 7, a force is applied from the sorting bar 14 to the conveying means 6 via the weighing product 5, and the weighing means 9 However, excessive force may be applied to cause damage. However, according to this example, the frame 8 of the conveying means 6 can slide in the sorting direction under this force, so that it is mechanically excessive with respect to the mechanism such as the conveying means 6 and the sorting bar 14. There is no risk of adding a burden.

  That is, as shown in FIG. 7, the frame 8 of the conveying means 6 receives this force and moves in the horizontal direction by the gap t in the sorting direction, and the end portion 35 of the frame 8 is fixed to the fixing member 36 of the base 3. The mechanical force on the mechanism of the apparatus can be avoided, for example, it is possible to avoid the adverse effect on the weighing means 9 due to the force of the sorting bar 14. In this state, a gap t is generated between the stopper member 33 and the weighing means 9, and the positioning return member 34 is deformed by the dimension t and exerts an elastic force corresponding to the deflection amount t on the weighing means 9. The force is smaller than that directly applied to the weighing means 9, and the weighing means 9 is not adversely affected.

  When the NG product is sent to the discharge roller conveyor 16, the sorting bar 14 returns to the original position, and the frame 8 of the conveying means 6 held by the sorting bar 14 moves along with the bent positioning return member 34. The normal position can be restored by the restoring force.

  That is, when the conveying means 6 is in the normal position, the elastic means of the positioning return member 34 is in contact with the weighing means 9 in a state where it is not substantially deformed, and the position of the conveying means 6 relative to the weighing means 9 is determined. When the force from the sorting bar 14 is released after the transport means 6 has moved in the sorting direction during sorting, the transport means 6 moved in the sorting direction returns to the normal position shown in FIG. 5 by the elastic force of the positioning return member 34. be able to.

2. Second embodiment (second example)
FIG. 8 is a view showing a weight sorting apparatus 1 ′ of the second example in the normal position, where FIG. 8 (a) is a partially cutaway plan view showing the weighing means 9, and FIG. 8 (b) is the weighing means 9; FIG. FIG. 9 is an exploded sectional view showing the weighing means 9 of the weight sorting apparatus 1 ′ of the second example in the normal position.

(1) Configuration of the second example The configuration of the second example is different from the first example in the slidable mounting structure of the conveying means 6 and the weighing means 9, and the other configurations are substantially the same as the first example. Only the different parts will be described with reference to FIGS. 8 and 9, and the other parts will be denoted by the same reference numerals as those in the first example, and the description thereof will be omitted as necessary.

  As shown in FIGS. 8 and 9, the upper surface of the weighing means 9 has a pair of slide rails 31 ′ in a slanting manner so that the downstream side in the sorting direction is lifted in parallel in the plan view and in the side view. 31 'is attached. An inclined pedestal 37 corresponding to the two slide rails 31 ′ and 31 ′ is attached to the lower surface of the frame 8 having a plurality of conveying rollers 7. Two sliders 32 are attached so as to correspond to the slide rails 31 ′ and 31 ′, and are slidably engaged with the corresponding slide rails 31 ′. Further, a stopper member 33 made of an elastic member such as rubber is attached to the lower surface of the pedestal 37 at a position downstream of the sorting direction.

  As shown in FIG. 8B, when the frame 8 is in a normal position where no external force is applied, the stopper member 33 is lowered along the slide rail 31 'to the upstream side in the sorting direction, and downstream in the sorting direction. The stopper member 33 is brought into contact with one side surface of the weighing means 9 in this position, whereby the frame 8 is positioned with respect to the weighing means 9.

  As shown in FIG. 8B, when the frame 8 is in the normal position and the frame 8 is positioned with respect to the weighing means 9 by the stopper member 33, the frame 8 is downstream in the sorting direction. A gap t of a predetermined size is formed between the side end 35 and the fixing member 36 of the base 3, and the frame 8 is arranged in the sorting direction (diagonally) by this horizontal gap t. It is configured to be movable upward).

(2) Operation of Second Example Next, the operation in the above configuration will be described focusing on the operation different from the first example.
The weight measurement result is out of the allowable range, the drive cylinder 15 is driven, the sorting bar 14 moves downstream in the sorting direction, and the measured weighing product 5 (defective product, NG product) on the conveying means 6 is removed. When pushing out in the sorting direction, if the friction between the weighing product 5 and the conveying roller 7 is large, or if the weighing product 5 moved in the sorting direction is engaged with the gap of the conveying roller 7, the conveying is performed. Since the frame 8 of the means 6 can be slid and moved upward in the sorting direction by receiving this force, there is no possibility that an excessive load is mechanically applied to the mechanism such as the conveying means 6 and the sorting means.

  That is, the frame 8 of the conveying means 6 receives this force and moves upward in the sorting direction by the horizontal gap t, and the end portion 35 of the frame 8 comes into contact with the fixing member 36 of the base 3. A mechanically excessive load on the mechanism of the apparatus can be avoided, such as by receiving the force and thereby avoiding adverse effects on the weighing means 9 due to the force of the sorting bar 14. In this state, a gap t is generated in the horizontal direction between the stopper member 33 and the weighing means 9.

  When the NG product is sent to the discharge roller conveyor 16, the sorting bar 14 returns to the original position, and the frame 8 of the conveying means 6 held by the sorting bar 14 is moved to the slide rail 31 'by its own weight. Along the sliding direction downward along the sorting direction, it is possible to return to the normal position shown in FIG.

  Even if the discharge roller conveyor 16 on the downstream side of the sorting direction and the transport surfaces of the transport means 6 are substantially coincident with each other, the ascending dimension of the frame 8 in this example is small. Even if it slides diagonally upward, there is no substantial problem in delivery of the weighing product 5.

3. As described above, according to the embodiment of the present invention, since the measurement unit 4 and the sorting means (sorting bar 14) are arranged close to each other, the overall length of the machine is short. As a result, it is possible to shorten the occupying dimension of the apparatus in the production line of the factory, and it is possible to shorten the total time required for measuring and sorting the weight.

  Further, when the weighing product 5 moving in the transport direction is applied with a force by the sorting bar 14 and discharged in the sorting direction, the friction between the weighing product 5 and the transport means 6 is large, or the weighing product 5 is moved in the sorting direction. Even when the measured product 5 is engaged with the transport means 6, the transport means 6 moves along the slide rails 31 and 31 'to abut against the base 3 and transmit the force. Therefore, there is no fear that an excessive load is mechanically applied to the mechanisms such as the weighing means 9, the conveying means 6, and the sorting bar 14.

  Further, the conveying means 6 can determine the required position in contact with the weighing means 9 in the normal position, and when the force from the sorting bar 14 is released after the sorting operation, the conveying means 6 moved in the sorting direction is positioned. It can return to the normal position by elastic means such as the return member 34 or its own weight.

  In the example described above, the measuring unit 4 and the sorting unit (the sorting bar 14) are configured and installed as a mechanically integrated device via the guide rail 11, the moving body 12, and the like, but are not limited thereto. Alternatively, the measurement unit and the selection unit may be configured and installed as mechanically separate devices. In this case, as shown in FIG. 10, the sorting bar 14 as the sorting means only needs to be disposed on the conveying means 6 of the measuring section 4, and the measuring section and the sorting means are mechanically separated. As shown by an arrow A in the figure, the position at which the sorting bar 14 pushes out the object to be measured on the conveying means 6 can be arbitrarily adjusted.

  Alternatively, in the case where the measuring unit 4 and the sorting bar 14 are configured and arranged as mechanically separate devices in the same manner as above, the sorting bar 14 is arranged in parallel with the conveying direction by the conveying means 6 as shown in FIG. However, if the drive cylinder 15 is configured so that the sorting bar 14 can be translated in the obliquely downstream direction of the transport direction by the transport means, the measured object is discharged while being transported downstream by the transport means 6. Since it can extrude to a roller conveyor, the mechanical burden added to each mechanism, such as a conveyance means 6 and a sorting means (sorting bar 14), can be reduced.
