Abstract

To solve a problem that the higher a speed, the more difficult it is to eject during movement, and the more frequently jamming occurs, when receiving products ejected at a constant pitch from a previous process, accumulating a specified quantity thereof, and ejecting the products in the next process.SOLUTION: An R plate and a stop plate suitable for a product dimension are attached at an accumulation starting point O point in a dimension that allows the product to pass through. A guide plate in a pre-process of the R plate is in a shape of a screen or board, a slide bearing is installed to move the R plate and the stop plate back and forth, and a timing belt with a sabot motor is attached to an end thereof so as to be operated before and after. When the product reaches an ejection position, the product stops and is ejected. At the same time, the R plate and the stop plate advance in an opposite direction to perform accumulation. When ejection is completed, the R plate, the stop plate, and a product bucket return to the starting point O to perform accumulation.SELECTED DRAWING: Figure 3

Description

The present invention is a system in which the products discharged from the packaging machine in the previous process are collected at a constant pitch and sent to the next process.

In all accumulation methods, point O is fixed and accumulation is performed in the direction of travel.
(1) Collect products discharged in multiple rows, and collect N times the number of rows. There is also a method in which products discharged in one or two rows are distributed into the required number of rows, and multi-row lines are created and integrated to accumulate.

(2) Feed multiple rows of products onto a wide guided conveyor, feed them into the pitch of a pin conveyor, etc. at a 90° position, attach a suction arm to the robot, and pick up the required number of products and collect them, increasing the speed. If there is a shortage, the number of robots will be increased.

(3) A system in which the products that fall at the end of a row of pin conveyors are counted by the rotating part of the sprocket and dropped into a bucket.

(4) A method that operates intermittently or continuously, feeding the product into the vane, turning it 90 degrees, and pushing it out from a specified number of vanes.

(5) Carton products are fed by line pressure on a belt conveyor, top, bottom, left, right. rotation. Allocating required quantities in different directions Both methods pose problems when conditions change, such as an increase or decrease in the set quantity or a change in processing speed.

While sliding the products on the guide board with pins, etc., keep the products being transported in the correct posture, drop them into the product bucket, and smoothly and systematically move the specified number of products that have been stacked from the discharge position to the next process. Delivering to the packaging machine and collecting the products must be carried out without interrupting the products being delivered at high speed.

Do not decide on pre-process machines such as filling machines based on their accumulation processing capacity; rather, choose the machine with the highest capacity based on the product conditions, etc., and carry out accumulation using a method that is suitable for that capacity. Does not limit process capabilities.

The means by which the invention solves the problem

The products in Figure 1 are smoothly slid on the guide plate at a pitch of 1.4 times the W dimension or more, and transported from the top or side at the accumulation section, and the F guide plate is moved to the R-shaped guide plate stop plate. The details in Figure 4 are changed. The R plate and stop plate are attached to a linear slide bearing and then set to a timing belt with a servo motor so that they can be moved left and right by the rotation of the servo motor. The joint with the front guide plate has a screen or board structure as shown in Figure 4, and is designed to be operable before and after moving. The shape of the R section is as shown in Figure 5, with a passing dimension of H dimension, and a product bucket with a height of W dimension with a clearance of the product bucket (H + α) on the lower side, and an intermittent operation driven by a servo motor or a product transfer pin conveyor. Drive in synchronization with etc.

The product sent by the pin passes through the R plate and the stop plate, and enters the product bucket at the right time. When the product reaches the discharge position, the product stops and the discharge operation is performed at a speed of 45 m/min or less. , performs discharge work in a stable manner such as one-way movement, reciprocating movement, and box motion.

At the same time, the R plate and stop plate at the O point advance in the opposite direction to the On point one pitch at a time, and when the discharge work is completed, the R plate, stop plate, and product bucket return to the O point and accumulate at a speed of 45 m/min or less. do the work.

If the product speed is high, such as discharge speed and return speed of the R plate stop plate of 45 m/min or more, two accumulation stations will be installed, two independent locations such as product buckets, and the product transport will be extended to the first accumulation station and the second accumulation station. Need to be integrated and divided to be more stable.

停止し、次のアタッチメントでかつぐようなタイミングでピッチ間に送り込むタイミングとする。
それでも遅れが出、噛込みが、発生するよつであれば、再サイド同一スピードで走るベルトを設ける方式 Figure 2-(1) The figure shows that the rotation speed of the product discharged from the pillow packaging machine and the 90° reversal pin conveyor are synchronized.

The timing is such that it stops and is fed between pitches at a time when it is carried over to the next attachment.
If there is still a delay or jamming occurs, install a belt that runs at the same speed on the other side.

Figure 2-(2) shows a synchronous feeder in which the speed of the conveying device such as the lower pin conveyor is set several percent faster than the speed of the feed in the previous process. Empty buckets are generated accordingly. A method in which the accumulating device (R plate, stop plate) stops for a few percent of that amount, and the lower product bucket does not become empty.

Claims (1)

(1) A product that can be conveyed with pins, etc., slides on a guide plate, R plate, etc. at a pitch of 1.4 times or more the width W of the product, is conveyed, and is transported at the end of the guide plate and the start of the R plate. The R plate and the stop plate are attached to each other, and the R plate and the stop plate are attached to a linear guide, and the timing belt with servo motor is installed as a step that can be moved back and forth (2) R. A product bucket is installed below the plate and stop plate, and the height of the partition plate is the product width W, the width is the product, and the height (H + α).The product bucket transports the product and the product is discharged. When the product reaches the position, it stops (3) and discharges the product. At the same time, the R plate, stop plate, and product bucket return to the O point. This is an accumulation method with a step.
