Abstract

PURPOSE:To array and supply long-sized objects at approximately the same height by providing a store place to an inclined chute for transferring the long- sized objects to a horizontal conveyor, measuring the weight of the long-sized objects in said place and controlling the speed of the horizontal conveyor according to the measured weight. CONSTITUTION:The terminal of a rabbit conveyor 1 for conveying bolts B which are the long-sized objects and the horizontal net conveyor 9 are connected by the inclined chute 2 and the bolts B are transferred through plural gates 3, 5-7. The storage place 4 is formed of part of the chute face of the inclined chute 2 and a 1st gate 3. The weight of the bolts B stored transiently therein is measured by a weight measuring instrument 8. The feed of the net conveyor 9 is controlled via a driving power part 11 by a rotary encoder 12 and a feed control circuit 13 according to the measured weight value. The bolts B loaded on and conveyed by the net conveyor 8 are thereby arrayed in the same direction at approximately the same height.

Description

Detailed Description of the Invention (Industrial Application Field) The present invention aligns long objects such as bolts and bottles in the same direction,
Moreover, the present invention relates to a device for adjusting the loading height of a conveyor to a level between roads.

(Prior art) Conventionally, in hardening, tempering, and boxing work of bolts, bottles, etc., when a conveyor has to convey a certain number of long bolts, bottles, etc. in a certain amount of fff, Even when long objects of a certain number and weight are transferred onto the ConoVear, the bolts and bottles are often placed in random positions and at different heights because the direction of the bolts and bottles is not determined (see Figure 3).

(Problems to be Solved by the Invention) If items are loaded in random positions and at different heights and transported, various problems will occur in the next process. for example,
When heat-treating a bolt (1) The bolt bends during the heat treatment due to its own weight due to entanglement.

(2) Due to variations in heat treatment conditions, stable, high-quality bolts cannot be produced.

(3) Intertwined heaters! This will result in loss and damage to the conveyor net.

(4) There are many voids due to entanglement, and the filling rate is poor.

(Means for Solving the Problems) The present invention aims to solve these problems and provide a device for arranging long objects such as bolts that can align long objects and supply uniform heights. The gist of the system is to connect the terminal end of the rabbit conveyor and the horizontal conveyor through an inclined chute, and to form a hot water storage in the middle of the inclined chute with a part of the neat surface of the inclined chute and the first gate. A weight measuring device is provided to measure the weight of the workpieces stored in the hot water storage chamber, and a plurality of gates are provided on the downstream side of the first gate of the tilted ute; The present invention is an alignment device for long objects such as bolts, which has a horizontal conveyor feed control circuit that measures the weight and determines the feed of the horizontal conveyor so that the stacking height is the same according to the weight value.

(Function) In the second invention, a long object is cut into small pieces by a rabbit conveyor, and the cut pieces are fed into an inclined chute from the end thereof.

Quite long objects are lined up at this stage of the rabbit conveyor. Slope /: The long object thrown into L-to slides along the inclination /--to the first game!・The hot water is stopped and stored in the hot water tank.

The weight of the long objects stored in the hot water storage tank is measured by a weight measuring device, and the measured weight value is input to the feed control circuit, which allows the long objects of that weight to be placed at a set loading height. The placement length of the horizontal conveyor, that is, the conveyor feed, is controlled so that The conveyor speed increases approximately in proportion to the weight of the long object in the hot water storage.

Moreover, when the long objects stored in the hot water storage tank slide down the inclined chute, the long objects are stored in the hot water storage tank in a fixed direction.

When the first gate is opened, the long objects stored in the hot water storage will slide into the lower gate and be temporarily stored.
When the gate is opened, the items slide down one by one to the lower gate, and are finally transferred to a horizontal conveyor. Long objects are not necessarily temporarily stored in the gates below, and can be skipped or dropped directly onto the horizontal conveyor.

In this way, as the long objects slide down the inclined chute, they are almost perfectly aligned, and since the horizontal conveyor is sent according to the amount, the long objects are conveyed while being stacked at the height between the tracks. It is.

(Embodiment) The embodiment shown in the drawings is an example in which long bolts are quenched, lined up in a heat treatment plant for tempering, and loaded on a conveyor at a constant height.

In this example, three gates are provided below the first gate, and by completely discharging the workpieces inside the gates, the lofts are completely separated and the intrusion of foreign matter is also prevented.

In addition, a net conveyor is used as a horizontal conveyor, so that the bolts can be hardened and transported to the tempering plant with the bolts on them.

9) Rotary encoder that measures the feed rate, +I
n is a feeding control circuit that increases the moving distance of the net conveyor in proportion to the weight of the stored bolts (411C) and controls the feeding of the net conveyor (9) so that the set bolt loading height is achieved ( B) is a bolt.

(Effects of the Invention) As described above, according to the present invention, long objects can be aligned in a certain direction and stacked on a horizontal conveyor at the same height. This has the advantage of not causing damage to the heater.
