As conventional cutting and weighing equipment, for example, weigh laver, sesame seeds, dried fish meat, dried vegetables (hereinafter referred to as “Kayaka”) stored in instant noodle bags such as ramen, udon, soba and fried noodles. Some bags are packed in small bags.
FIG. 8 is a front sectional view showing an outline of a conventional cutting and weighing apparatus.
As shown in FIG. 8, the cut-out weighing device 110 is connected to a hopper 112 for storing the object to be weighed 111 and a discharge part 112 a of the hopper 112, and is cut downward to cut out the object to be weighed 111. A cut-out cylinder 113 having an appropriate length, a rotating means (motor rotating mechanism) 115 for rotating the cut-out cylinder 113, a receiving member 116 for receiving the object to be weighed 111 dropped from the cut-out cylinder 113, and the receiving member 116 An opening / closing lid 117 provided at the discharge port 116a, a weighing device (load cell) 118 for weighing the object to be weighed 111 received by the receiving member 116, and an opening / closing means for opening / closing the opening / closing lid 117 provided at the receiving member 116. (Solenoid) 119.
In addition, the to-be-weighed item 111 here means the granular material which can be cut out from the inside of the hopper 112, a piece-like body, a small lump-like body, etc.

This cut-out weighing device 110 is configured to detachably provide a cylindrical attachment 141 capable of adjusting the cut-out of the object to be weighed 111 between the discharge portion 112a of the hopper 112 and the cut-out cylinder 113. This attachment 141 adjusts the cut-out of the object to be weighed 111 by changing the inner diameter of the internal flow path.
The attachment 141 is provided with a cut-out projection of the object to be weighed 111 at the end portion on the hopper 112 side, and a cut-out spiral body of the object to be weighed 111 is provided at the discharge portion 112a on the hopper 112 side.
Thus, the object to be weighed 111 discharged from the discharge portion 112a of the hopper 112 is continuously cut out from the downwardly inclined cutting cylinder 113 rotated by the rotating means 115, dropped into the receiving member 116, and the weighing machine 118. When the weight reaches a predetermined weight, the cutting is stopped, and the opening / closing lid 116a of the receiving member 116 is opened by the opening / closing means 119, whereby the weighed object 111 is discharged. Therefore, it is possible to eliminate high costs due to excessive or undercutting of the object to be weighed 111 and troublesome treatment of defective products. In particular, since the object to be weighed 111 gradually flows in the cut-out cylinder 113 having an appropriate length that is inclined downwardly, the object to be weighed 111 is made uniform, and a fixed amount is discharged from the lower end of the cut-out cylinder 113. The cutout amount can be adjusted by changing the rotation speed and / or inclination of the cutout tube 113.

In addition, since a removable attachment 141 is mounted between the discharge portion 112 a of the hopper 112 and the cutout cylinder 113, when the object to be weighed 111 in the hopper 112 is introduced into the cutout cylinder 113, the object to be weighed 111 The cutout adjustment can be facilitated according to the product type such as size and shape.
Furthermore, the weighed material (eg, sesame) 111 having good fluidity discharged from the discharge portion 112a of the hopper 112 has different internal diameters (different effective passage cross-sectional areas) when passing through the attachment 141. Since the flow rate is adjusted by passing, the flow rate of the weighed object 111 having a small particle size can be easily adjusted.
When the attachment 141 rotates together with the cut-out cylinder 113, the cut-out projection crushes, for example, the solid weighing object 111 in the vicinity of the discharge part 112a of the hopper 112. Therefore, the measurement object 111 in the vicinity of the discharge part 112a of the hopper 112. It is hard to clog.

When the attachment 141 rotates together with the cutting cylinder 113, the cutting spiral body rotates in a predetermined direction. However, when the cutting spiral body rotates in the same direction as the bending direction of the cutting spiral body, an object to be weighed in the vicinity of the discharge portion 112a of the hopper 112 is obtained. 111, when the inflow to the cut-out cylinder 113 is promoted, and the rotation of the cut-out spiral in the direction opposite to the bending direction of the cut-out spiral body, By suppressing and selecting the forward / reverse rotation direction according to the type of the weighed object 111, the range of the cut-out adjustment of the weighed object 111 is widened. In this way, the object to be weighed 111 in the hopper 112 is gradually dropped onto the receiving member 116 while rotating the cutting cylinder 113 whose axis a is inclined downward by the rotating means 115, and is weighed by the weigher 118. Therefore, it is possible to accurately cut out a predetermined amount, and it is possible to eliminate high costs due to excessive or undercutting of the object to be weighed 111 and troublesome handling of defective products.
In particular, the cut-out adjustment for introducing the object to be weighed 111 in the hopper 112 into the cut-out cylinder 113 by the attachment 141 detachably attached to the discharge part 112a of the hopper 112 is a product type such as the size and shape of the object to be weighed 111. This can be done easily (see Patent Document 1).

The second embodiment is different from the first embodiment in that the weighed object 2 in the first embodiment is a powder for instant noodles, freeze-dried products, and chopped paste. However, the objects to be weighed 2 ′ in the second embodiment are in the form of granules having substantially the same shape, and can be counted individually. For this reason, instead of the scraping bar 10 used in the first embodiment, a counting guide spring 15 is used so that granular raw materials can be counted individually. The counting guide spring 15 rotates together with the inner cylinder.
In FIG. 6, the same components as those in FIGS. 1 to 5 are denoted by the same reference numerals, and the description thereof is omitted.
As shown in FIG. 6A, the granular raw material 2 ′ is individually fed out along the spirally formed spring 15 through the spiral counting guide spring 15.
Further, as shown in FIG. 6B, the counting guide spring 15 formed in a spiral shape is arranged along the inner circumference 4bb of the inner cylinder 4b, and the inner circumference 4bb is a spring of the counting guide spring 15 itself. It is pressed into the inner circumference 4bb by pressure and is fitted into the inner cylinder 4b.
Next, as shown in FIG. 6C, the counting guide spring 15 is a coiled spring having a constant diameter.
In this way, the inner cylinder 4b is provided with the counting guide spring 15 which is formed by pressing the inner circumference 4bb with its own spring pressure along the inner circumference 4bb of the inner cylinder 4b. As the counting guide spring 15 rotates, particles such as tablets can be accurately and individually fed along the spiral to facilitate counting.

FIG. 7 shows the operation of the cutting cylinder according to the second embodiment of the present invention. FIG. 7A shows that the counting guide spring is attached to the inner cylinder, and the inner cylinder and the counting guide spring are firmly fixed together. 6A is a partial enlarged cross-sectional view shown in FIG. 6A showing a state in which the materials are individually fed in the direction of the arrow in the figure. It is.
As shown in FIGS. 7A and 7B, in the cut-out weighing device 1 ′, the inner circumference 4bb is pressed by its own spring pressure along the inner circumference 4bb of the inner cylinder 4b and fitted into a spiral shape. A counting guide spring 15 is provided.
The leading end 15a of the counting guide spring 15 is disposed so as to coincide with one end on the discharge side of the inner cylinder 4b, and the rear end 15b of the counting guide spring 15 is disposed at a position close to the impeller device 8. The direction in which the granular raw material 2 can move to the discharge side of the cutting cylinder 4 is defined as the normal rotation direction depending on the winding direction of the spiral coil spring. Moreover, when rotating the cutting cylinder 4 in the reverse rotation direction, individual feeding can be performed by changing the winding direction of the coil spring. You may change suitably.

In this way, the inner cylinder 4b is provided with the counting guide spring 15 that is fitted along the inner circumference 4bb of the inner cylinder 4b by pressing the inner circumference 4bb with its own spring pressure. The raw material 22 can be moved along a groove formed by being surrounded by the inner circumference 4bb and the guide spring 15 for counting, and granular materials such as tablets can be accurately and individually fed to facilitate counting.
Then, the weighing object 22 discharged from the discharge portion 3a of the hopper 3 is continuously cut out from the cutting cylinder 4 rotating by the rotating means 5, dropped into the receiving member 6, and a weighing device 7 provided with a load cell. Is weighed. When the weighing object 22 of the receiving member 6 reaches a predetermined weight, the opening / closing lid 6b of the receiving member 6 is opened by the electric opening / closing means 6c, and the weighed weighing object 22 is discharged from the receiving member 6. Thus, it is possible to cut out a predetermined amount, thereby eliminating the high cost and troublesome processing due to excessive or undercutting of the object to be weighed 22. In particular, since the objects to be weighed 22 gradually flow in the cutting cylinder 4 that is rotationally driven, the objects to be weighed 22 are individually fed, and are discharged from the lower end of the cutting cylinder 4 constantly. The cutout amount can be adjusted by changing the rotation speed of the cutout cylinder 4.
