Description

[Detailed Description of the Invention] <Industrial Application Field> The disclosed technology belongs to the structural technology field of a panel mounting device to a frame of a vibration device of an electromagnetic feeder used in a product weighing device or the like.

<Summary of the gist> Therefore, this invention supplies products such as seasonings from the supply hopper of a weighing device for seasonings to the next processing device such as the weighing hopper while being supported by an electromagnetic vibrating device. This invention relates to a device for attaching a vibrating device to a frame of a feeder panel, in particular,
A bush having a circular cross section or the like is integrally fixed in advance to the feeder panel of the vibrating feeder, and a hole is bored in the radial direction so as to intersect with the axial direction at the tip of the bush.
An L-shaped lever is supported on the frame of the vibrating device via a bearing so that the front half of the lever can rotate freely and move forward and backward, and a cam is installed between the hole in the bush and the bearing at the front of the lever. The cam surface of the cam surface can be attached to the vibrator, or can be moved back and forth in the axial direction, and the cam surface can be brought into contact with the frame of the vibrating device, or can be brought into contact with the inner surface of the hole in the bush, and the bush can be vibrated by operating a lever. This invention relates to a panel mounting device for a vibrating feeder that moves perpendicularly to the frame of the device so that the feeder panel of the vibrating feeder is firmly and integrally fastened to the frame of the vibrating device.

<Prior art> As is well known, vibrating devices are widely used in various devices, and some types use the vibration of the vibrating device itself directly, but other types of devices are used by attaching other panels, etc. to the vibrating device. There are many devices that utilize this vibration. For example, in the so-called combination weighing device 1 used in supermarket pack centers as shown in FIG. In this embodiment, the weight is supplied to the pool hopper 3 of a predetermined number of heads, and the weight is weighed by the weighing hopper 4 located below the pool hopper 3. Weights that approximate the predetermined weight value are combined and weighed. A radiation trough 5 as a vibrating feeder is connected to several heads for distributed supply of products to the pool hopper 3.
In order to feed the products from the distribution table 2 to the pool hopper 3 by the radiation trough 5 with an average weight, the products are supported by an electromagnetic vibration device 6 provided on the device frame and given vibration. The water is supplied to Pool Hopper 3.

However, this type of weighing device requires regular and irregular maintenance, inspection, replacement, etc., and therefore it is necessary to clean the sliding surfaces of each mechanical part and other related mechanical parts. , therefore,
It is necessary to disassemble each mechanical part of a spatially compact device as much as possible to make it easier to clean.

<Problems to be solved by the invention> In this case, the vibration feeder 5 of the radiation trough can be attached and detached from the vibration device 6 by providing a so-called snap lock 7 on the lower side of the panel 6, as shown in FIG. This type of attachment device is designed to be attached and detached in a one-touch manner, and as shown in FIG. .

Therefore, although it is easy to attach and detach the vibrating feeder 5 to and from the vibrating device 6, the weighing function will be affected unless the vibrations from the vibrating device 6 to the vibrating feeder 5 are reliably transmitted during operation of the weighing device. However, since the spring 8 is interposed in the mounting device, the vibration from the vibration device 6 to the vibration feeder 5 is absorbed or suppressed, so that the vibration is reduced. There is a disadvantage that the function of the feeder may be reduced.
If the product has a shape that has a large mutual friction coefficient on a microscopic level, there is a problem in that vibration cannot be supplied as designed unless the set vibration is applied to the product, and it is difficult to adjust it.

Therefore, depending on the product, or even if the product is the same, if the same cycle changes, accurate supply may not be performed and accurate measurement may not be performed.

Of course, if the so-called "Megoroshi" type of strong installation is used, the vibration of the vibration system can be transmitted as designed, but on the other hand, as mentioned above, it is difficult to remove and cannot be cleaned for maintenance, inspection, etc. This is an inconvenience.

The purpose of this invention is to solve the competing problems of attaching and detaching a panel of a vibrating feeder to and from a weighing device using a vibration mechanism in a weighing device, etc. based on the above-mentioned conventional technology, and transmitting proper vibration during operation. The challenge was to make it possible to attach and detach the vibration device with a single touch and to make cleaning etc. easier, but while the device is in operation, the vibration is transmitted accurately to the vibration feeder as designed, and it is also easy to adjust. In this way, it is an object of the present invention to provide an excellent panel mounting device for a vibrating feeder that is useful in the field of vibration technology application in various industries.

<Means/effects for solving the problems> In order to solve the above problems, the structure of this invention, which is based on the above-mentioned utility model registration claims, is based on a vibrating feeder supported by a vibrating device. is connected to a processing device such as a hopper in the previous stage, and is connected to a processing device in the next stage such as a weighing hopper,
It is adapted to transport a predetermined object to be processed, and
To attach the panel of the vibrating feeder to the vibrating device, a bush with a circular cross section or the like that is integrally fixed to the panel is inserted into the insertion hole provided in the frame of the vibrating device, and then inserted into the bearing provided in the frame of the vibrating device. The tip of the inserted L-shaped lever is inserted into a hole perpendicular to the axial direction of the bushing and is fixed to the lever by rotating the lever, or the cam surface of the cam that can freely slide in the axial direction becomes a vibrating device. or the inner surface of the hole to perform a predetermined cam action, and as a result, the button moves in the axial direction with respect to the frame of the vibrating device, thereby causing the panel of the vibrating feeder to interact with the frame of the vibrating device. is firmly tightened, the vibration of the vibrating device is transmitted to the panel of the vibrating feeder according to the setting, and the transfer of the processed material is carried out smoothly.Thus, the vibrating feeder can be moved to the vibrating device for maintenance, inspection, cleaning, etc. When removing the lever from the bearing, the cam is disengaged from the opposing cam surface by rotating the lever in the opposite direction, and the vibrating feeder is loosened by the vibrating device. The tip is removed from the hole in the bush, and the vibrating feeder is smoothly removed from the vibrating device, so that maintenance such as predetermined cleaning can be carried out smoothly.
