Abstract

PURPOSE:To make it possible to certainly perform accurate metering, by providing a falling time control part for averaging the falling time of a substance to be metered reaching a discharge port from an upper edge opening to the inner peripheral surface of a gathering hopper. CONSTITUTION:A gathering hopper 3 is formed into a funnel shape so that a rectangular opening part having round corners is formed and a bottom side becomes narrow. Each corner is formed into a round shape so that a substance to be metered is rapidly slipped down and generates no excessive concentration while a barrier plate 13 having a shape opened sidways is provided to the center of each oblique surface of the hopper to form a falling time control part. This falling time control part 13 reduces the falling speed of the substance to be metered when the substance to be metered is contacted with said control part 13 and has a function for allowing the substance to be metered to bypass.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides an introduction weigher, more specifically, a pair of dispersion plates that transport and disperse objects to be weighed in opposite directions, and supply troughs are provided in parallel in the transport direction of the dispersion plates. A metering hopper is provided in each supply trough, and a collecting hopper is provided in which the lower ends of all the weighing hoppers face under the distribution plate and a lid plate that can be opened and closed is provided at the discharge port, and the supply trough allows the supply trough to The present invention relates to an improvement in a collection hopper in a combination weigher that transports objects to be weighed to weighing hoppers and selects a set of weighing hoppers that reaches a set weight or a weight close to the set weight.

The collection hopper mentioned above may have a rectangular, funnel-shaped opening as shown in Figure 7, but such a hopper (3) has wave gauges at the right angles of the four corners. - Because the objects gather in a row, the falling distance is long in that part, the falling time is slow, and near the middle the falling time is relatively fast, so the falling time differs for each weighing hopper and there is a large amount of flutter.

41 is a discharge port, and a hot plate (not shown) is provided at the bottom of the discharge port to temporarily store the boat objects.

The time for the object to be weighed to reach this discharge port (41) differs for each weighing hopper because the falling distance differs.

In Fig. 8, the vertical axis represents each weighing hopper (A1 to I(xl

There is a possibility that the received "1" inheritance may be mixed up. Furthermore, when the cycle interval of combination selection is lengthened in order to lengthen the interval Q3), there is a problem in that the combination extraction efficiency becomes extremely low.

Another way to lengthen interval (2) is to
It is good to have a uniform time for the objects to be weighed to reach the discharge port (41) of the clear Hofpar.
Drop↑゛ At the same time, slow Naebu Hopper & 1 and 2 Ryo 5 hit it.
If the falling time of the objects is made faster and the times are made equal, the arrival time of each weighing hopper (AI, 2, A5) will overlap, the total weight will be shorter, and the interval CB) can be lengthened. Similarly, as shown in FIG. 10, the interval (b) can be lengthened by aligning the falling times m1 of A2 and A5, which have fast falling times, so that their arrival times are aligned.

The present invention has been made in view of the above-mentioned conventional circumstances, and its purpose is to provide a collection hopper that can average the falling time of textiles to reduce the rate of n1 combined discharge η. To facilitate the opening/closing timing of a hot plate provided at a discharge port without causing any trouble.
