[Embodiment of the invention]

 Embodiment 1 FIG. 1 is a perspective view showing the first embodiment, FIG. 2 is a plan sectional view showing the first embodiment, and FIG. 3 is a sectional view taken along line AA of FIG.

In FIG. 1, reference numeral 1 denotes an elongated plate-like band forming a balance weight having a constant weight per unit length, which is rolled and wound. It is attached (loaded) to the machine (loading unit) 2 and is sequentially fed out. The feeding machine 2 may be of a horizontal mounting type as shown in FIG. 1 or a vertical mounting type. The band 1 is made of a material that forms a balance weight such as lead.

In the machine frame 3, a sending unit 4 for pulling out the band 1 attached (loaded) to the feeding machine (loading unit) 2, and a length of the band 1 pulled out by the sending unit 4. Measuring means 5 for measuring at least one of the height and the weight, and detecting that at least one of the length and the weight of the band 1 has reached the set value by the measuring means 5 and adding the measured value to the measured set value. Cutting means 6 for cutting the body 1 are provided.

In the present embodiment, the sending means 4 is formed by a pair of rolls 7a and 7b driven by a motor 8, and the belt 1 is opposed to each other when passing between the pair of feed rolls 7a and 7b. It is pulled out by the feed rolls 7a and 7b rotating in the direction, and is sent out. The pair of feed rolls 7a and 7b may be not only one pair but also a plurality. In this example, two pairs are shown. The drive of the motor 8 is transmitted to the feed rolls 7a and 7b via the transmission mechanism 9. In this example, gears 11, 12, 13, and 14 are shown as the transmission mechanism 10. That is, the gear 11 fixed to the drive shaft 9 of the motor 8 and the gear 13 fixed to the rotatable shaft 15 to which the feed roll 7a is fixed are meshed via the intermediate gear 12, and the gear 13 and a gear wheel 14 fixed to a rotatable shaft 16 on which the feed rolls 7b are fixed, meshes with each other, and the rotation of the motor 9 causes the feed rolls 7a and 7b to rotate in opposite directions to each other. ing. Even when a plurality of pairs of feed rolls are provided, they are driven by the motor 8 via the transmission mechanism. The transmission mechanism is not limited to gears, but may be other known means. For example, a combination of a belt and a pulley.

The sending means 4 measures at least one of the length and the weight of the band 1, stops at the output of the measuring means 5 detecting that the set value has been reached, and activates the cutting means 6. 17 is provided.

The measuring means 5 can measure at least one of the length and the weight of the band 1, and conventionally known means are employed. For example, a storage device is built in the control means 17 and the weight per unit length of the band 1 is inputted and stored. When the required weight is indicated, the length measured by the measuring means 5 is stored in the storage means. When the corresponding weight set value is reached, the control means 17 detects it, outputs a detection signal, stops the sending means 4, and activates the cutting means 6.

Examples of the measuring means 5 include a pulse motor, a sensor, and a rotary encoder. In the case of a sensor, a method is used in which identifiers at predetermined intervals are provided on the belt 1 with irregularities, paint, or the like, and this is detected and measured by the sensor. This identifier may be provided at regular intervals and the sensor may be used to measure the amount of movement to reach the set value, or the identifier may be provided in advance at a location corresponding to the set value and detected by the sensor. In the case of a rotary encoder, it is provided on the rotation axis of the feed roll, or on the rotation axis of the roller to be measured, and measures the length from the number of rotations.

In the case of a pulse motor, the motor 8 is a pulse motor, which is connected to the control means 17 and rotates according to the number of driving pulses output from the control means 17. The number of pulses corresponds to the feeding length of the band 1. Therefore, when the required weight is input with the key 18 shown in FIG. 1, it is converted into the length of the band 1, the feed length (length of the band to be cut) is determined, and the pulse is determined based on the feed length. By determining the number of driving pulses of the motor and driving the pulse motor, the belt 1 is fed by the determined length. Then, the cutting means 6 is operated to cut the band 1, and a balance weight of a predetermined weight (instructed weight) can be obtained. When this pulse motor is used, the measuring means 5 of FIG. 2 becomes unnecessary.

The cutting means 6 has a cutting blade 19 connected to a cylinder 20 and is driven by a cylinder 20. Further, a solenoid may be used instead of the cylinder 20. The cylinder 20 or the solenoid that operates the cutting blade 19 is connected to the control means 17 and operates with an output that detects that the band 1 has been fed by a predetermined value. Accordingly, as described above, the belt 1 is operated by the detection output of the control means 17 when the measuring means 5 measures the predetermined value or the command from the control means 17 that the predetermined value is sent out by the pulse motor. Disconnect. As a result, a balance weight having a predetermined weight can be obtained.

Second Embodiment In a second embodiment, as shown in FIG. 4, a press-type member 21 that moves forward and backward with the cutting blade 19 is provided on the side of the cutting blade 19, and the band 1 is formed. The cutting piece 1a to be pressed at the same time as the cutting is formed into a predetermined shape, for example, a semicircular arc shape, which becomes a balance weight. The press die member 21 is composed of, for example, a lower die 21a and an upper die 21b. The lower die 21a is fixed to the cutting blade 19, moves forward and backward with the cutting blade 19, and cuts the strip 1 at the same time as cutting the band 1. Is pressed by the lower mold 21a into the upper mold 21b to form a predetermined shape, for example, a semicircular arc shape as shown in FIG. In this press, the cut balance weight is formed in accordance with the shape of the mounting portion of the object to be balanced, thereby facilitating mounting and improving aesthetics. Therefore, the press mold member 21 is formed according to its shape. In the drawings, an example in which the lower mold 21a is fixed to the cutting blade 19 is described. However, the present invention is not limited to this. For example, the lower mold 21a may be fixed to the piston of the cylinder 20 via a connecting member. . Further, the same applies to a case where a solenoid is used instead of the cylinder 20. Other components are the same as those of the first embodiment, the same components are denoted by the same reference numerals, and overlapping description will be omitted.

(Embodiment 3) The third embodiment has a structure in which the sending means 4 presses and pushes out the band 1 and the other parts are the same as those in the first embodiment. Only the explanation will be given, and the explanation of other overlapping parts will be omitted. FIG. 6 is a main part plan view showing the third embodiment. In the figure, the sending means 4 is constituted by a pressing moving body 22.

The pressing moving body 22 pulls out the band 1 by moving while pressing the band 1. The pressing of the band 1 is performed using the weight of the pressing moving body 22 or using the biasing force of a spring. The movement of the pressing moving body 22 is utilized by converting the rotational movement of a cylinder or a motor into a linear movement. In FIG. 6, it is indicated by a cylinder 23.

Further, in this example, the measurement by the measuring means can be performed by measuring the movement amount of the pressing moving body 22 in addition to the one described in the first embodiment.

However, since the weight of the band 1 is constant per unit length, a balance weight of a desired weight can be freely manufactured by designating length or gravity as input information. Moreover, since the input information can be programmed in advance and set and input to the control means, the balance weight required by one switch can be automatically manufactured.

The long plate-like band forming the balance weight may be formed by laminating an adhesive (adhesive), a cushion material, a release paper, and the like on the back surface.

Therefore, there is no need to prepare various units having different unit weights as in the related art, so that it is economical and the cost can be reduced.

Further, the sending means is a pressing moving body which moves and sends while pressing a pair of driven feed rolls or belts, and the cutting means has a cutting blade connected to a cylinder or a solenoid, and Since it is driven by a solenoid, it can be easily controlled by the control means, has a simple structure, is easy to manufacture, and can be provided at low cost.

Further, a press-type member is provided, and the strip can be cut and pressed at the same time to form a cut piece serving as a balance weight into a predetermined shape. Therefore, the balance weight is adjusted to the shape of the mounting portion of the object to be balanced-balanced. The mounting can be facilitated, and the appearance after mounting can be improved.
