Abstract

PURPOSE:To allow transfer operation to be positively accomplished by configurating a device in such a way that the saddle suspension position of an upstream conveyor is detected at the transfer site so as to determine the saddle suspension position of a downstream conveyor in a conveyor as referred to the titled in a hot strip equipment. CONSTITUTION:When a saddle 3 of an upstream saddle conveyor 1 arrives at the transfer site, the saddle 3 is detected by a detector 6. And the time starts being counted until the conveyor 1 is suspended after the saddle 3 has been detected by a detector 5 at the loading site of the upstream conveyor 1 allowing the distance that the conveyor 1 has moved during the period of the time, to be computed. In addition, the difference in distance between the saddle detector 6 which is set in advance, and a suspension position detector 14 of a downstream conveyor 11 is determined. On the basis of this difference determined, the distance moved of the downstream conveyor 11 after the saddle 13 of the downstream conveyor has been detected 14, is controlled. This configuration allows the suspension position for both the upstream and downstream conveyors to correspond with each other permitting transfer operation to be positively accomplished.

The conventional conveyor is configured as described above, and when the position detector (5) detects the saddle (3) of the upstream conveyor (1), the upstream conveyor (1) stops and the material is placed on the saddle (3). Load (4) and move in the direction of the line indicated by the arrow. This moving upstream conveyor (1) stops when the next saddle (3) is detected by the position detector (5).

The upstream conveyor (1) repeats this operation while conveying the material (4) to the downstream side.

On the other hand, the downstream conveyor α and the saddle (2) are detected by the stop position detector α◆, and the saddle (to) is stopped at a fixed position below the transfer and loading.

In this state, when the saddle (3) carrying the material (4) of the upstream conveyor (1) arrives at the transfer section and stops, the downstream conveyor α force increases and the saddle (3) of the downstream conveyor r11 (

[Problem that the invention seeks to solve]

In the conventional conveyor as described above, the stop position in the transfer section of the upstream conveyor (1) is determined by the position detector (5) at the loading section of the material (4), so the conveyor chain Due to factors such as slack in the chain, or mounting errors in the saddle (3), there may be variations in the stopping position of the saddle (3) on the upstream conveyor in the transfer section. There was a problem in that the transfer could not be carried out reliably.

Another problem was that in order to solve this problem, it was necessary to frequently repair the conveyor.

The present invention was made to solve this problem, and an object of the present invention is to provide a material transfer control device for a saddle chain conveyor that can reliably transfer materials.

[Means for solving problems]

A material transfer control device for a saddle chain conveyor according to the present invention includes a transfer section position detection means for detecting a stop position of a saddle loaded with material on an upstream side saddle chain conveyor in a transfer section; A stop position determining means is provided for determining a saddle stop position of the downstream side saddle chain conveyor in accordance with a detection signal of the means.

[Effect]

In this invention, the saddle stop position of the upstream side saddle chain conveyor (referred to as M lower conveyor) in the transfer section is detected, and the saddle of the downstream side conveyor is stopped in accordance with this stop position, so that material transfer is possible. The loading position can be determined accurately.

〔Example〕

FIG. 1 is a schematic diagram showing an embodiment of the present invention, and in the figure, (1) to (5) and α-o4 are the same as those in the conventional example. (6) is a saddle detector that detects the stop position of the saddle (3) of the upstream conveyor (1) in the transfer section, and (7) is a pulse sensor attached to the motor (2) that drives the upstream conveyor (1). signal generator, (to)
is a pulse signal generator attached to the motor (2) that drives the downstream conveyor α force.

FIG. 2 shows a block diagram of the control device of the embodiment shown in FIG.
2) is the count end gate, (a) is the pulse counter, and (c) is the saddle detection ff installed on the upstream conveyor (1).
A distance setting device that presets the distance in the line direction between the L unit (6) and the stop position detector α◆ provided on the downstream conveyor 01, (A) is a differential amplifier, and (2) is a counter.

The operation of the embodiment configured as described above will be explained. When the saddle detector (6) detects the saddle (3) loaded with material (4) on the upstream conveyor (1) moving in the line direction, the count start gate (2) closes and the pulse signal generator The number of pulses output from (7) is started by the pulse counter ■. Thereafter, when the position detector (5) provided in the upstream loading section detects the saddle (3) of the loading section, the gate 4 for ending counting is opened.

The count of the pulse counter (counter) is finished and the movement of the upstream conveyor (1) is stopped. Pulse counter (
When the saddle detector (6) detects the position of the saddle (3) until the upstream conveyor (1) stops, the pulse width is multiplied by the number of pulses.
1) The moving distance is calculated and this moving distance signal (Ll) is output to the differential amplifier (A). The differential amplifier (c) converts this moving distance signal (Ll), the distance signal (L3) between the saddle detector (6) set in advance in the distance detector (2), and the stop position detector α◆ of the downstream conveyor α ), that is, the necessary travel distance required for the downstream 1-side conveyor αη to move after the stop position detector a4 detects the saddle (to) where the material (4) is transferred to the downstream conveyor CL. Signal (L
Find t). This required travel distance signal (L,) is input to the counter (c), and the counter (c) generates a pulse signal generator ( Compare the moving distance signal (L4) of the downstream conveyor αυ output in 2) with the required moving distance signal (Li), and calculate both signals (Lt) and (Li).
When they match, the downstream conveyor α is stopped.

Therefore, the saddle (to) that transfers the material (4) on the downstream conveyor α port is connected to the upstream conveyor (1) in the transfer section.
The saddle can be stopped at the same position as the saddle (3). In this state, when ascending the downstream conveyor α stage,
The material (4) on the upstream conveyor (1) can be reliably transferred onto the saddle (to) of the downstream conveyor <11).

In the above embodiment, the distance traveled by the saddle in the transfer section was determined by calculating the number of pulses from the pulse signal generator (7), but the same effect as in the above embodiment can be obtained by actually measuring it using a distance meter or the like. can play.

As explained above, in this invention, the saddle stop position of the upstream conveyor of the material transfer section is actually measured, and the downstream conveyor is stopped so that the saddle of the downstream conveyor is aligned with this stop position. The loading position can be determined accurately, the material can be transferred reliably, and repairs to the conveyor required due to elongation of the conveyor chain can be reduced.
