Description

  The present invention relates to a tilting weighing device for weighing contents to be put into a container.

  Conventionally, Patent Document 1 discloses that contents such as fruits and vegetables supplied from a conveyor are put into a container whose opening is opened upward, and the weight of the contents put into the container is measured by a weighing machine. ing. The weighing machine measures the weight of the contents added to the container as the contents are put into the container. Moreover, in order to prevent the contents dropped from the conveyor onto the container from jumping out from the opening of the container, it is preferable to set a small drop from the end of the conveyor to the opening or bottom of the container. For example, the container may be tilted as disclosed in Patent Documents 1 and 2.

  However, as shown in FIGS. 10A and 10B, the depth [d] from the opening 205 to the bottom surface 207 of the containers 201 and 203 and the total length [w] that is the dimension in the longitudinal direction of the opening 205 The ratio varies depending on the container specifications. When the flat container 203 with d <w is tilted with respect to the horizontal plane as compared with the container 201 with d ≧ w, the number of contents 209 that can be stored in the container 203 is extremely reduced. Further, the contents 209 can easily roll out from the opening 205. For this reason, it is not preferable to uniformly incline containers of all specifications from the viewpoint of placing the contents in the container.

Show.

  As shown in FIGS. 5A and 5B, the transport means 55 is a roller conveyor that supports the containers 3 by rollers 73 that are supported by a conveyor frame 71. The conveyor frame 71 is joined to the housing 77 via hinge pins 75. The tilting means 79 formed of an air cylinder causes the conveyor frame 71 to pivot about the hinge pin 75 in the direction of the arrow θ or in the opposite direction as the piston rod 81 advances and retreats. Although one roller 73 appears in the drawing, a plurality of rollers 73 are arranged in parallel in the direction of arrow Y in FIG.

  As a drive source for rotating the roller 73, an endless belt 85 that travels in the direction of the arrow Y may be applied. In this case, as shown in FIG. 5A, the horizontal posture of the container 3 supported by the roller 73 is transmitted from the endless belt 85 to the roller 73 with the roller 73 in contact with the endless belt 85. It is conveyed in the direction of arrow Y. When the roller 73 supports the horizontal container 1, the container 1 is similarly transported.

  As shown in FIG. 5B, the rotational force of the roller 73 is cut off with the conveyor frame 71 tilted in the direction of the arrow θ, but the drive source 87 linearly moves the pusher 89 in the direction of the arrow Y. Thus, the inclined container 3 supported by the roller 73 is conveyed in the same direction. Reference numeral 90 indicates a guide rail that slidably receives the container 3 in an inclined posture.

  The supply means 63 arranges a belt conveyor 93 that conveys the contents 27 in the direction of the arrow X in front of the belt conveyor 91 that conveys the contents 27 in the direction of the arrow Y, and ends the belt conveyor 93 at the large outlet. 61. The sub-feeding means 65 is arranged in front of the belt conveyor 95 adjacent to the belt conveyor 91 with a roller conveyor 97 that can convey the contents 27 in a line in the direction of the arrow X. It is a thing.

  The belt conveyor 95 of the auxiliary supply means 65 has a narrower belt width than the belt conveyor 91 of the supply means 63, and the number of contents 27 dropped from the dispensing outlet 62 of the auxiliary supply means 65 per predetermined time is the supply amount. The number of contents 27 dropped from the large outlet 61 of the means 63 is smaller. The roller conveyor 97 of the sub supply means 65 is preferably capable of dropping the contents 27 one by one from the dispensing outlet 62.

  As shown in FIGS. 6A and 6B, the sub-weighing means 67 causes the roller 99 to be supported by the conveyor frame 101 and joins the conveyor frame 101 to the housing 105 via the hinge pin 103. The load received is measured by a load cell. This load cell is provided at the bottom of the base plate 43 fixed to the housing 105. The tilting means 107 composed of an air cylinder causes the conveyor frame 101 to pivot about the hinge pin 103 in the direction of the arrow θ or in the opposite direction as the piston rod 109 advances and retreats. Although one roller 99 appears in the figure, a plurality of rollers 99 are arranged in parallel in the direction of arrow Y.

  As a drive source for rotating the roller 99, an endless belt 111 that travels in the direction of arrow Y may be applied. In this case, as shown in FIG. 6 (a), in a state where the roller 99 is in contact with the endless belt 111, the rotational force is transmitted from the endless belt 111 to the roller 99, and the horizontal container 3 supported by the roller 99 is It is conveyed in the direction of arrow Y. When the roller 99 supports the horizontal container 1, the container 1 is similarly transported.

  Next, the operation in which the tilting weighing device 17 weighs the contents 27 put into the containers 1 and 3 will be described. It is assumed that the following operations are performed based on a program written in a storage medium that can be accessed by a CPU in which a drive source is instructed by an operator, electrical signals from sensors, or a CPU that controls each drive source. In addition, the English letter attached to the beginning of the sentence is an index for dividing the operation process.

  A: The inclination means 23 shown in FIG. 2 makes the movable receiving material 21 the attitude | position extended horizontally. On the other hand, the conveyor 57 shown in FIG. 4 conveys the containers 1 in the horizontal posture in the direction of the arrow X, and the containers 1 ride on the rollers 73 of the conveying means 55 shown in FIG. The conveying means 55 drives the roller 73 to convey the container 1 in the direction of arrow Y. Thereby, as shown in FIG. 1A, the horizontal container 1 is received by the fixed receiving member 19 and the movable receiving member 21.

  B: The belt conveyors 91 and 93 of the supply means 63 shown in FIG. 4 are started. As a result, the contents 27 are dropped from the large outlet 61 toward the opening 11 of the horizontal container 1 shown in FIG. 2, and the load is added to the load of the container 1. Based on this added load, the weighing means 29 weighs the contents 27 put into the container 1. The upper limit of the load of the contents 27 to be stored in one container 1 is set in advance. This is referred to as the total weight below.

  C: Immediately before the load of the contents 27 dropped from the large outlet 61 reaches the total weight, the belt conveyors 91 and 93 stop and the dropping of the contents 27 is cut off.

  D: While the process C is being performed, the conveyor 57 supplies a new empty container 1 following the container 1 described above to the conveying means 55. The above steps B and C are repeated for the succeeding container 1, and the transporting means 55 transports the succeeding container 1 in the direction of the arrow Y. In this process, the succeeding container 1 hits the preceding container 1 in which the content 27 immediately before reaching the total weight hits the preceding container 1, so that the preceding container 1 includes the fixed receiving material 19 and the movable receiving material. 21 is pushed out in the direction of the arrow Y and is transferred to the roller 99 of the sub-weighing means 67 shown in FIG.

  E: The belt conveyor 95 and the roller conveyor 97 of the auxiliary supply means 65 are activated. As a result, the contents 27 are dropped from the dispensing port 62 into the opening 11 of the container 1 supported in a horizontal posture by the roller 99, and the load of the contents 27 is added to the load of the container 1. Based on this added load, the sub-weighing means 67 weighs the contents 27 dropped onto the container 1 from the dispensing port 62. When the total of the load of the contents 27 dropped from the large outlet 61 of the supply means 63 in the process B and the load of the contents 27 dropped from the small outlet 62 in this process reaches the total weight, The belt conveyor 95 and the roller conveyor 97 are stopped, and the dropping of the contents 27 is cut off.

  F: The sub-weighing means 67 rotates the roller 99 to convey the horizontal container 1 in the direction of the arrow Y, and causes the container 1 to ride on the carry-out conveyor 69 shown in FIG. At the same time, the carry-out conveyor 69 is activated to carry out the entire container 1 to another place. Thereafter, the tilting weighing device 17 may perform the steps A to F again, but can perform the following steps.

  G: The inclination means 23 shown in FIG. 2 inclines the movable receiving member 21 as shown in FIG. The conveyor 59 shown in FIG. 4 conveys the horizontal containers 3 in the direction of the arrow Y, and the containers 3 run on the rollers 73 of the conveying means 55 shown in FIG. The tilting means 79 tilts the conveyor frame 71 in the direction of the arrow θ, so that the container 3 supported by the roller 73 is tilted. On the other hand, as shown in FIG. 6B, the tilting means 107 of the sub-weighing means 67 turns the conveyor frame 101 in the direction of the arrow θ.

  H: The transport means 55 drives the roller 73 to transport the container 3 in the direction of arrow Y. Thereby, as shown in FIG. 1B, the other end 7 of the inclined container 3 is received by the movable receiving member 21, and the lower surface 9 of the container 3 is received by the holding member 25.

  I: The belt conveyors 91 and 93 of the supply means 63 are started. As a result, the contents 27 are dropped from the large outlet 61 toward the opening 11 of the inclined container 3, and the load is added to the load of the container 3. Based on this added load, the weighing means 29 weighs the contents 27 put into the container 3.

  J: Immediately before the load of the contents 27 dropped from the large outlet 61 reaches the total weight, the belt conveyors 91 and 93 stop and the dropping of the contents 27 is cut off.

  K: While the above step J is being performed, the conveyor 59 supplies a new empty container 3 following the container 3 described above to the transport means 55. The above steps H and I are repeated for the succeeding container 3, and the transporting container 55 transports the succeeding container 3 in the direction of the arrow Y. In this process, the succeeding container 3 hits the preceding container 3 in which the content 27 immediately before reaching the total weight hits the preceding container 3 that has already been charged, so that the preceding container 3 includes the movable receiving member 21 and the holding member 25. Is pushed in the direction of the arrow Y, and is transferred to the roller 99 of the sub-weighing means 67 shown in FIG.

  L: The belt conveyor 95 and the roller conveyor 97 of the auxiliary supply means 65 are activated. As a result, the content 27 is dropped from the dispensing port 62 into the opening 11 of the container 3 supported by the roller 99 in an inclined posture, and the load of the content 27 is added to the load of the container 3. Based on this added load, the sub-weighing means 67 weighs the contents 27 dropped into the container 3 from the dispensing port 62. When the total of the load of the contents 27 dropped from the large outlet 61 of the supply means 63 in the step I and the load of the contents 27 dropped from the small outlet 62 in this step reaches the total weight, The belt conveyor 95 and the roller conveyor 97 are stopped, and the dropping of the contents 27 is cut off.

  M: The tilting means 107 turns the conveyor frame 101 in the direction opposite to the arrow θ, and brings the roller 99 into contact with the endless belt 111 as shown in FIG. In this state, the container 3 returns to the horizontal posture, and the sub-weighing means 67 rotates the roller 99, thereby transporting the container 3 in the horizontal posture in the direction of the arrow Y and causing the container 3 to ride on the carry-out conveyor 69. At the same time, the carry-out conveyor 69 is activated to carry out the entire container 3 to another place. Thereafter, the tilting weighing device 17 may perform the steps G to M again, but can perform the steps A to F.

  According to the tilting weighing device 17 described above, when the contents 27 are put into the container 1, the container 1 is placed in a horizontal posture and is received by the fixed receiving member 19 and the movable receiving member 21, and is put into the container 1. It is possible to prevent the rolled contents 27 from rolling out from the opening 11. When the contents 27 are put into the container 3, the other end 7 and the lower surface 9 of the inclined container 3 are received by the movable receiving member 21 and the holding member 25, respectively. The drop from the conveyor or the like to the opening 11 or the bottom surface 13 of the container 3 can be set small so as not to jump out.

  Further, according to the tilting type weighing device 17, since the postures of the containers 1 and 3 can be determined by the above steps A and G before the contents 27 are put into the containers 1 and 3, a plurality of containers having different forms from each other can be obtained. There is an advantage that a container selected from 1 and 3 can be appropriately supported by a simple structure.

  In addition, since the total height of the container 1 is lower than that of the container 3, the container 1 to which the contents 27 are dropped in the process B is higher than the container 3 to which the contents 27 are dropped in the process I. It is preferable to be received by the fixed receiving member 19 and the movable receiving member 21. For this reason, the raising / lowering means 34 raises the operating rod 50 of the electric motors 46 and 48 as shown in FIG. 2 in the process B, and the contents from the large outlet 61 to the opening 11 or the bottom surface 13 of the container 1. 27 can be reduced.

  The operation of the lifting means 34 described here is continued in the steps B to E described above. In the step A, the electric motors 46 and 48 of the elevating means 34 lower the respective operating rods 50. As a result, the height at which the fixed receiving material 19 and the movable receiving material 21 receive the lower surface 9 of the container 1 in the horizontal posture matches the height at which the roller 73 of the conveying means 55 receives the lower surface 9 of the container 1. In the step F, the electric motors 46 and 48 lower the operation rods 50 respectively. Accordingly, the height at which the fixed receiving material 19 and the movable receiving material 21 receive the lower surface 9 of the container 1 in the horizontal posture matches the height at which the carry-out conveyor 69 receives the lower surface 9 of the container 1.

  Furthermore, in the steps G to M, the electric motors 46 and 48 keep the respective operating rods 50 lowered to the lower limit. However, as shown in FIG. One operating rod 50 may be raised. Thereby, the movable frame 31 is inclined, and the angle at which the container 3 received by the fixed receiving member 19 and the movable receiving member 21 is inclined with respect to the horizontal plane can be increased or decreased.

  As shown in FIGS. 2 and 3, the position of the opening 11 of the container 1, 3 is displaced in the direction of the arrow X with respect to the large outlet 61 of the supply means 63 or the opposite direction depending on the posture of the container 1, 3. To do. The moving means 33 advances and retracts the fixed receiving member 19 and the movable receiving member 21 together with the movable frame 31 with respect to the large outlet 61 in the direction to cancel this, thereby opening the opening 11 and the large outlet 61 of the containers 1 and 3. Can be kept at a proper distance.

  The transport means 55 can move the conveyor frame 71 up and down with respect to the housing 77 while maintaining the horizontal posture of the container 1 supported by the roller 73 before transporting the container 1 in the direction of arrow Y in the process A. You may do it. This is because the lifting means 34 raises the fixed receiving material 19 and the movable receiving material 21 in the step B, so that the conveying means 55 raises the conveyor frame 71 in advance so that the horizontal posture supported by the roller 73 is reached. This is because the height of the container 1 is made equal to the height of the container 1 supported by the fixed receiving material 19 and the movable receiving material 21 in the step B.

  Differences from the first embodiment will be described below. As shown in FIG. 7, the tilting weighing device 18 according to the second embodiment of the present invention is obtained by directly joining the weighing means 29 to the lower part of the movable frame 31 and omits the lifting means described above. .

  As shown in FIGS. 8 (a) and 8 (b), the tilting type weighing device 18 has the contents 27 from the supply means 63 for supplying the contents 27 above the containers 1 and 3 to the opening 11 of the containers 1 and 3. A guide member 113 for guiding the guide member 113 and an advance / retreat means 115 for moving the guide member 113 forward and backward from the supply means 63 toward the opening 11 of the containers 1 and 3 are attached to the belt conveyor 93.

  The guide member 113 is a tongue-like chute that is positioned below the belt conveyor 93 and that is advanced and retracted by advancing and retracting means 115 that is a drive source such as a hydraulic cylinder. When the guide member 113 is extended by the advancing / retracting means 115, it is preferable that the tip end portion thereof is deformed in an arc shape downward. The length by which the advance / retreat means 115 extends the guide member 113 from the large outlet 61 is preferably adjustable. In this case, as the drop of the content 27 from the large outlet 61 to the opening 11 or the bottom surface 13 of the containers 1 and 3 increases, the advancing / retracting means 115 moves the guide member 113 forward from the large outlet 61 to increase the content. The impact of the 27 falling can be suppressed small.

  Alternatively, as shown in FIGS. 9 (a) and 9 (b), the supply unit 63 that supplies the content 27 above the containers 1 and 3 can be extended and retracted to guide the content 27 to the opening 11 of the containers 1 and 3. The guide member 113 and the advancing / retracting means 115 for advancing and retracting the guide member 113 from the supply means 63 toward the opening 11 of the containers 1 and 3 may be attached to the belt conveyor 93. The guide member 113 does not have to be cylindrical, and may be a groove or a flat sheet.

  When the supply means 63 supplies the contents 27 above the container 1, the advance / retreat means 115 extends the guide member 113 as shown in FIG. Thereby, the guide member 113 guides the contents 27 dropped from the large outlet 61 of the supply means 63 toward the opening 11 of the container 1. Alternatively, when the drop from the large outlet 61 of the supply means 63 to the opening 11 or the bottom surface 13 of the container 3 is small, the guide member 113 is unnecessary. In this case, the advance / retreat means 115 can shorten the guide member 113 as shown in FIG.

  It should be noted that the present invention can be implemented in a mode in which various improvements, modifications, or variations are added based on the knowledge of those skilled in the art without departing from the spirit of the present invention. The two types of containers 1 and 3 shown in the first and second embodiments do not limit the form of the container applicable to the present invention, and a container selected from three or more containers having different forms from each other is transported. It may be supplied to the means 55. In the step G, the angle at which the movable receiving member 21 is tilted and the angle at which the conveyor frame 71 is tilted coincide with each other at about 45 ° with respect to the horizontal plane. This angle is a design matter.

  A rubber sheet or the like for receiving the containers 1 and 3 may be bonded to any one of the fixed receiving material 19, the movable receiving material 21, and the holding member 25. The guide member 113 and the advance / retreat means 115 may be applied to any of the tilt type weighing devices 17 and 18. Further, even if the moving means 33 is omitted, the implementation of the present invention is not hindered.

  The present invention is a useful technique for weighing an article while putting the article into any container.
