Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a combination weighing machine that discharges articles as a predetermined weight by combining them.

[0002]

[Prior Art]

 FIG. 4 is a side view showing a conventional combination weighing machine. The articles are conveyed by a conveyor or the like and loaded from the upper center of the combination weighing machine 40. This article is radially fed by a central conical feeder 41 to a plurality of linear feeders 42 provided on the sides. The straight feeder 42 supplies the articles to the intermediate hopper 43 at the bottom. The intermediate hopper 43 is provided in the lower part after storing a predetermined amount of articles, and is discharged to the weighing hopper 44 for weighing the articles.

Then, the weighing values of the plurality of weighing hoppers 44 are combined to achieve the target weight value, and the articles of the weighing hopper 44 corresponding to this combination are discharged onto the collecting chute 45 at the lower part. The collecting chute 45 collects the articles having a predetermined weight and temporarily stores them in the discharge hopper 46 portion. The discharge hopper 46 opens the discharge door 46a at a predetermined timing and discharges the article.

A packaging machine 50 is provided below the combination weighing machine 40, and packages the discharged articles at predetermined timings. Therefore, the main body frame 49 of the combination weighing machine 40 is provided on the pedestal 52 having a height of about the packaging machine 50. This gantry 52 can be raised and lowered by a person for inspection and cleaning of the combination weighing machine 40, and the upper surface of the gantry 52 is provided over the entire circumference of the apparatus, and includes an intermediate hopper 43, a weighing hopper 44, The collecting chute 45 can be attached and detached.

[0005]

[Problems to be solved by the device]

 However, the conventional combination weighing machine cannot be easily removed because the discharge hopper 46 is provided at a high position on the packaging machine 50. In order to remove the discharge hopper 46, a stepladder must be erected on the lower part of the combination weighing machine 40, and the step must be performed on this stepladder, which is unstable. Was hard to do. The discharge hopper 46 is attached and detached once a day for cleaning. The discharge hopper 46 of the combination weighing machine 40 cannot be attached and detached from the upper side of the gantry 52.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a combination weighing machine capable of easily attaching and detaching the discharge hopper for cleaning, inspection, and the like.

[0007]

[Means for Solving the Problems]

 In order to achieve the above object, the combination weighing machine of the present invention divides an object to be measured into a plurality of hoppers, and then collects the measured values of the respective hoppers having predetermined weights, and collects them at a predetermined timing. In the combination weighing machine that discharges from the hopper 4, a main body frame 49 that supports each component of the apparatus and is fixed on a pedestal 52 for inspection, and is rotatable upward with respect to the main body frame 49. It is characterized in that the collar portion 4a of the discharge hopper 4 is provided with a rotating plate 3 having a support plate 5 which is detachably engaged.

[0008]

[Action]

 The objects to be weighed after the combination weighing are stored in the discharging hopper 4 and discharged at a predetermined timing. This discharge hopper 4 has a collar 4a engaged with an engagement piece 5 of the rotating plate 3, and can be removed by sliding the discharge hopper 4. The rotating plate 3 is rotatable upward, so that the discharge hopper 4 can be detached from the gantry 52 side for inspection, and attachment / detachment operation can be performed on this gantry 52 together with other hoppers.

[0009]

【Example】

 FIG. 1 is a side view showing a discharge hopper portion which is a main part of the combination weighing machine of the present invention. In this embodiment, the general structure of the combination weighing machine is the same as that of the conventional example, and the same parts are designated by the same reference numerals and the description thereof will be omitted.

The discharge hopper is provided on the lower surface of the main body frame 49 and on the lower end of the collecting chute 45. An opening 49a is formed in the central portion of the main body frame 49 so as to vertically penetrate therethrough, and a collecting chute 45 is provided in the opening 49a. The collecting chute 45 is configured to be detachable from the upper side of the main body frame 49, and this operation is performed on the gantry 52.

Further, a support plate 2 is provided around the outside of the collecting chute 45 in the opening 49 a. The support plate 2 is provided with a rotating plate 3 which is rotatable upward at a hinge 3a portion. The rotating plate 3 is bent and formed so that its lower surface is in contact with the lower end 45b of the collecting chute 45, and its central portion is opened. A fixing screw 3c for fixing to the support plate 2 is provided on the side opposite to the hinge 3a. A discharge hopper 4 shown in an enlarged view of FIG. 2 is detachably provided on the lower surface of the rotating plate 3. A collar portion 4a is formed at two upper edge portions of the discharge hopper 4, and the collar portion 4a can be laterally fitted to a supporting piece 5 portion provided on the rotating plate 3 side.

The discharge door 4b of the discharge hopper 4 is biased by a spring 9 in a closing direction, and is rotatable about an upper shaft 4c. Then, the discharge door 4b is rotated to a position shown by a chain line in the drawing by the operation of the drive mechanism 10 connected to the engagement protrusion 4d, and discharges the article inside. The drive mechanism 10 is composed of a cylinder 12 one end of which is connected to a base piece 11 provided on the rotating plate 3. The tip of the rod 12a of the cylinder 12 is rotated at a shaft 13a portion in the attaching / detaching direction of the discharge hopper 4. A movable joint 13 is provided. The engagement groove 13b of the joint 13 has a shape corresponding to the engagement protrusion 4d of the discharge door 4b.

Next, the attaching / detaching operation of the discharge hopper 4 having the above configuration will be described. First, the operator removes the collecting chute 45 provided in the opening 49a from the upper side of the main body frame 49 on the gantry 52. After that, as shown in FIG. 3, the fixing screw 3c is removed from the upper side of the opening 49a, and the rotating plate 3 is rotated upward as shown in the drawing. As a result, the discharge hopper 4 is located above the body frame 49.

In this state, first, the engaging groove 13b of the joint 13 is removed from the engaging protrusion 4d of the discharge door 4b, and then the joint 13 is rotated around the shaft 13a. Then, by sliding the discharge hopper 4 toward the front in the drawing, the collar portion 4a is disengaged from the engaging piece 5 and can be taken out. Further, the discharge hopper 4, which has been cleaned and the like, can be attached in the reverse operation of the above. In this way, the discharge hopper 4 can be attached / detached on the base 52 like other hoppers, so that cleaning and inspection can be easily performed.

[0015]

[Effect of the device]

 According to the present invention, the rotating plate to which the discharge hopper is attached rotates so that the discharge hopper can be attached and detached on the pedestal. As a result, like all the other hoppers, all the hoppers can be attached and detached on the gantry, so that the workability of inspection and cleaning can be improved.
