Description

  The present invention relates to a combination weighing device having improved workability when a timing hopper attached directly under a discharge port of a collecting chute is attached and detached.

  Many combination weighing devices are installed in a bagging line for processed foods (hereinafter referred to as articles). FIG. 1 shows the bagging line disclosed in Patent Document 1 below. In this figure, a combination weighing device W is installed on a gantry ST on which an operator works, and a packaging device BM is connected to the lower stage via a timing hopper TH. The timing hopper TH receives the articles discharged from the combination weighing device W and temporarily stores them. When the lower packaging apparatus BM can be packaged, the timing hopper TH discharges the articles. The worker climbs up and down between the platform ST and the floor using a ladder R provided on the platform ST. Further, an article conveyed by a Z-type bucket conveyor ZC is supplied to the upper center portion of the combination weighing device W.

  By the way, in such a line for bagging processed foods, the entire apparatus is always washed at the end of work, so that the apparatus part in contact with the article, for example, the dispersion feeder DF and the radiation trough RF at the upper part of the apparatus, each hopper PH, WH and the assembly The chute CS, the timing hopper TH, and the like are detachably attached to the apparatus.

JP 2002-156462 A

  As described above, since most of the combination weighing devices are provided on the gantry ST shown in FIG. 1, when cleaning each part of the device, the operator climbs on the gantry ST and the pool hopper PH of the weighing unit or The weighing hopper WH is removed, then the dispersion feeder DF and the radiation trough RF are removed, and the collective chute CS is removed from the support leg L. Since the timing hopper TH is disposed below the gantry ST, the timing hopper located at a position higher than the extension of the operator must be removed while descending from the gantry ST and avoiding the packaging device BM. In addition, when installing them, the stairs R must be climbed up and down in the reverse procedure, so workers who have to clean daily need to be able to work more efficiently. is there.

  The present invention has been developed to solve this problem. It is an object of the present invention to provide a new combination weighing device in which all separable parts including a timing hopper can be attached and detached from the gantry.

  The combination weighing device according to the present invention measures an article dispersed in a plurality of paths by a distribution supply device by a weighing unit of each path, and then combines the articles into a predetermined mass based on the measured values measured by these weighing units. A combination weighing device that collects and discharges the collected articles to a lowermost timing hopper via a collecting chute, wherein the distributed supply device, the weighing unit, and a support base that supports the collecting chute are operated by an operator. An opening for taking out the timing hopper exposed from the lower side of the gantry from the outside of the collective chute is provided on the support pedestal. Is attached.

  The dispersion supply apparatus is composed of a dispersion feeder disposed in the center and a plurality of radiation troughs disposed radially around the periphery. The weighing unit includes a plurality of upper pool hoppers and the same number of lower weighing hoppers, which are arranged in a circle corresponding to each radiation trough. As a result, an operator who works on the gantry can remove the dispersion feeder and radiation trough of the decentralized supply device, each hopper and collecting chute of the weighing unit, and even the timing hopper exposed below the gantry on the gantry. Therefore, it is possible to reduce the number of times of climbing up and down the gantry and to increase the efficiency of the cleaning work. In addition, supporting a dispersion | distribution supply apparatus, a measurement part, and a collection chute means supporting the said member directly or indirectly.

  Further, the support base is in the form of a pallet with a central portion penetrating vertically, the collective chute is disposed in the through-hole, and the opening is formed in a region extending from the upper surface to the side surface of the support base, The reinforcing member is provided on the periphery of the opening on the upper surface side and on the periphery of the opening on the side surface side, respectively.

  Thereby, the fall of the support force which arises when a part of support stand is cut off as an opening part is reinforced with a reinforcement member. Therefore, since the supporting force that has been provided in the conventional support table can be maintained as before, the rigidity of the support table is ensured and the measurement accuracy is not affected.

  In addition, the reinforcing member corrects a change in vibration characteristics caused when a part of the support base is cut off as an opening.

  Thereby, the conventional measurement accuracy can be maintained using the conventional vibration elimination filter.

  Furthermore, the collective chute is a two-system collective chute that collects articles individually, and the timing hopper is a parallel hopper corresponding to each collective chute.

  There are two types of combination weighing devices: a single type that combines the distributed supply device and the weighing unit with a single set of collective chutes, and a double type that has two sets of collective chutes. Although there are four groups of shoots divided into two, the present invention is applicable to any type. In the case of a double type, the opening is provided for each timing hopper. Thereby, the opening of each opening is made small so that the strength and characteristics as a support base are not greatly reduced.

  In this case, the timing hopper is supported by a support frame and is provided so as to be movable from the discharge port of the collective chute to the opening, and is provided in the opening so as to be separable from the support frame. It is characterized by that.

  Thereby, since the timing hopper can be taken out from the upper surface of the support base outside the collective chute, the workability when attaching and detaching the timing hopper is improved.

  According to the present invention, since all the detachable members including the timing hopper can be removed from the pedestal on which the worker walks, workability when cleaning them is improved. In addition, changes in the characteristics of the support table due to the opening provided in the support table are also corrected by the reinforcing member, so that it is possible to maintain the same performance as before without reducing the measurement accuracy as a combination weighing device. it can.
