Description

[Detailed explanation of the invention] [Detailed explanation of the invention] (a) Industrial application field The present invention is used to position the material at a working position for cutting to a fixed length during the transportation process of materials such as steel plate sections. This invention relates to a traveling type sizing positioning device.

(b) Prior Art Conventional technology for positioning stoppers installed on conveyance lines for materials such as steel sheet shapes and the like is usually a portal-shaped traveling frame that is driven by a trolley and is equipped with lifting stoppers. After moving and setting the traveling frame to a predetermined position, the lifting stopper is lowered onto the conveyance path to act as an obstacle, and the traveling material is stopped at the fixed position by colliding with the stopper as an obstacle. I was using the configuration.

However, in such a conventional device, a large impact is applied to the stopper body and the gate-shaped frame, so it is necessary to have large rigidity to withstand the impact, and the equipment cost for this is large.

Moreover, since the material tends to separate from the stopper due to the reaction of the collision with the stopper, the conveyance roller must always be rotated in the feeding direction, which inevitably causes roller wear and scratches on the product. It was becoming. Furthermore, it has the disadvantage that the repair costs are high because it causes rattling due to impact.

These disadvantages can be alleviated to some extent by reducing the conveying speed, but since reducing the speed is extremely disadvantageous in terms of cycle time, the speed cannot be reduced, and therefore these disadvantages cannot be reduced. The occurrence of this was considered unavoidable.

(c) Problems to be solved by the invention The problem to be solved by the invention is to reduce the impact when the material is stopped and to perform positioning with high precision. It's about getting.

(d) Means for solving the problem The traveling type sizing positioning device of the present invention uses rollers and
A material detector that can be moved up and down, which detects the passage of material being conveyed by a table and instructs the roller table to stop, and a link mechanism to a support frame that is arranged parallel to the material conveyance line. a positioning means that is swingably suspended and pushes the material back to a predetermined position on the material transport line; and a cylinder that is mounted on the support frame and connected to the link mechanism,
a cylinder that operates the link mechanism to move the positioning means to a raised/retracted position relative to the positioning position and a lowered/advanced position from there; and a position fine adjustment mechanism that is capable of adjusting a set lowered positioning position of the positioning means. and a traveling carriage which is equipped with the material detector, the positioning means, the support frame, and the position fine adjustment mechanism and is capable of self-propelled in parallel to the material conveyance line, and the traveling carriage is fixed at a desired reference position. The above-mentioned problem is solved by constructing the clamp device with a flexible clamp device.

(E) Embodiment The traveling type sizing positioning device of the present invention, as shown in FIG. 1, is provided with a traveling carriage 2 that runs on a rail 1 in parallel to a conveyance line for material a. The traveling carriage 2 is equipped with a clamp mechanism 21 (FIG. 4) which will be described later, and is also equipped with a position fine adjustment mechanism 3 which can be further adjusted and moved on the traveling carriage. Positioning means 4
A material detector 5 is supported and protrudes onto the material conveyance line 6.

The positioning means 4 is held by a support frame 41 fixed to the tip of a protruding arm 31 that protrudes as an integral part of the position fine adjustment mechanism 3, and as is clear from FIGS. 2 and 3, the ring mechanism The material conveying line 6 is connected by four hanging arms 42.
is supported so as to be able to swing in parallel with the A cylinder 43 is provided at the upper part of the support pedestal 41, and a link 44 is provided at the tip of a piston rod 431 of the cylinder 43, which can simultaneously transmit rocking motion of a predetermined angle to the four hanging arms 42. As a result, when the piston rod 431 of the cylinder 43 is at the shortest stroke position _P1 (solid line position in Fig. 3),
The positioning means 4 is lowered to the set positioning position on the working level of the conveyor line 6, and when the rod 431 reaches the longest stroke position P ₂ (position indicated by the two-dot chain line in FIG. 3), the link 44 moves to the fulcrum P ₀ Since the rotation center changes by a predetermined angle θ, 4
The book hanging arm 42 similarly swings by an angle θ,
This makes it possible to move the positioning means 4 in parallel to the positioning position on the conveyance line 6 to the ascending and retracting position 4' (the position indicated by the two-dot chain line in FIG. 3).

The material detector 5 includes a light-emitting part 51 and a light-receiving part 52 that form a set and are arranged on the left and right sides of the conveyance path, or a reflective photocell type detector equipped with a light-emitting part and a light-receiving part is installed on the conveyance line 6. placed on only one side of the The material detector 5 is attached to the front part of the support frame 41 and can be moved up and down to the conveyance level by actuation of a cylinder 53.

The positioning fine adjustment mechanism 3 is a mechanism that finely adjusts the position of the support arm 31 along the conveyance line direction, and directly connects the arm frame 33, which is fitted to the guide frame 32 and moves, to the motor shaft 34. The screw shaft 341 and the nut member 331 fixed to the frame 33 are screwed together to allow fine adjustment and movement.

The traveling trolley 2 on which these parts are mounted is moved on the rails 1 by a traveling drive motor 22, but the wheels 23 on the trolley side that engage with the rails 1 are moved as shown in FIG. upper wheel 23
Three types of wheels: a, lower wheel 23b, and inner wheel 23c are assembled and engage with the rail 1 from three sides, top and bottom, thereby preventing the bogie 2 from derailing from the rail 1. .

The truck 2 is provided with a clamp mechanism 21 shown in FIG. This clamp mechanism 21
A clamp arm 213 that engages with an anchor hardware 212 of an anchor rail 211 previously provided along the
is operated by a clamp cylinder 214 to position and fix the trolley 2 at a desired position. Anchor hardware 212 is anchor rail 21
1, a large number of them are provided in advance at predetermined intervals L, or they are installed each time at a desired position.

As a guideline for moving the traveling trolley 2, a pointer (not shown) is provided on the trolley side, and a fixed scale plate (not shown) to match this is provided on a fixed part outside the trolley, or
Alternatively, a pulse measuring device may be attached to the cart to measure the rotational speed of the traveling motor 22.

(F) Operation In the device of the present invention, first, the anchor hardware 212 is placed at a predetermined position on the anchor rail 211 depending on the type of length to be determined. Next, the traveling trolley 2 is moved to a predetermined position of the anchor hardware 212 and stopped, and the cylinder 21 is activated to clamp and
Anchor hardware 212 is clamped by arm 213. As a result, the traveling carriage 2 is fixed at a desired reference position.

The positioning means 4 is initially placed in standby at the raised and retracted position 4', and is not installed at the level of the material passing through the conveying line 6. And material detector 5
Only the lower part is lowered and installed at the transport level.

When the material a is transported on the transport line 6 and the leading edge thereof is detected by the detector 5, the roller table forming the transport line 6 is commanded to stop, and the material a is moved to the positioning means. 4 is stopped on the conveyance level within a range where the leading end of the material a can come into complete contact with the positioning means 4, that is, at a position slightly beyond the positioning position. At this point cylinder 4
3 was activated, and the positioning means 4 was waiting above.
advances diagonally downward to the conveyance level and comes into contact with the tip of material a that has already stopped on the conveyance line 6,
While pushing back the material a by a small amount, it descends to a fixed position and stops. The position where the positioning means 4 has completely lowered, that is, the position where the push-back of the material a has been completely completed, is the predetermined positioning position, and the material a is accurately positioned at the fixed size position.

After positioning, the positioning means 4 is returned to the upper waiting position by the above-mentioned reverse operation, and is waited for the next sizing positioning of the material.

In setting the above-mentioned fixed size position, the position of the trolley 2 is first determined by the clamp mechanism 21, but if it is necessary to further adjust the error to some extent with respect to the reference length, the position fine adjustment mechanism 3 is used. This allows you to make adjustments and determine the exact position.

The material detector 5 can be raised and lowered freely, so after detecting the material, it is raised above the conveyance level to wait, but if there is no need to cross-feed the material after sizing to outside the line, it is Since it does not become a hindrance, it may be kept in the lowered position.

(G) Effect The traveling type sizing and positioning device of the present invention sizes the material by pushing it back a small amount by the positioning means after it has stopped, and since the impact applied to the device is extremely small, there is no repulsion etc. It is possible to stop at a fixed size position with high precision without any lag. Furthermore, since it is equipped with a minute feed mechanism, it is possible to provide plus and minus tolerances to the standard dimensions. Furthermore, by matching the minute feed stroke to the distance L between the anchor hardware, the fixed length can be set arbitrarily. Furthermore, since the impact is extremely small, the rigidity of the entire device can be kept small, and equipment costs can be reduced.
