BACKGROUND OF THE INVENTION Product manufacturers often store multiple products, sometimes referred to as product lots, and package them in cases for subsequent shipment to distributors. The quantity of product in a case is often referred to as the case lot quantity. It is not unusual for a manufacturer or distributor to open a case and distribute a product in a case lot amount or less. Combine with other products from other cases according to shipping order to meet individual customer requirements.

[0003] In order to adapt to the order of many kinds of products below the case lot quantity, the case of the kind of product selected by the manufacturer or distributor is operated, and the required number of units of products are taken from each case. Collect the collected products in a single container for shipping. This is commonly referred to as broken case order withdrawal. Conventionally, this work is manually performed by a person. However, manual case pick-up is a relatively slow process that is prone to pick-up errors. Such errors typically occur when an operator picks up or picks up an incorrect product or quantity from a case to meet an order, or forgets to pick up a particular product indicated by an order.

Automation of the broken case picking operation is a preferred solution to the inefficient and useless manual broken case order picking method. Some automatic pick-up systems (autos) often called automatic ordering systems (AOS)
Automated piking systems are well known in the art. In the conventional AOS, a terminal operator receives a product transportation command and inputs the product transportation command to a system host computer that handles a calculation and inventory control function for distribution work. When attempting to execute this command, the AOS central control computer commands the adaptation of the order in real time by automatically picking up and collecting the correct product and quantity from the case lot to complete the order. In such an automated system, the number of orders with incorrect adaptation and picking error (picking error)
The incidental costs associated with r) are minimized or eliminated.

A typical prior art AOS comprises a plurality of individual product cartridges packed with different types of products. These cartridges are
They are arranged in a matrix along the length of the belt. The products discharged from these cartridges are collected by a transportation collecting conveyor downstream of the place where the products are sent and collected so as to complete the order in accordance with the input transportation command. One example of a conventional matrix array AOS is shown in FIG. 1 and described in US Pat. No. 566,530. This specification refers to this description.

In order to properly collect the dispensed product in accordance with the shipping instructions, the central control computer effectively partitions the collection conveyor belt into sequential order zones separated by a buffer zone (FIG. 1). The computer will
The computer then ejects the proper product from the cartridge onto the conveyor as the ordered area assigned to the shipping order passes underneath. When each command zone for a transport directive reaches the downstream end of the conveyor belt, each product in the zone
It is placed in a shipping container (or tube) for further processing (eg, manual pick-up of additional product) as needed for shipping to the customer.

The product cartridge in the AOS further comprises some type of means for ejecting the product onto a collection belt moving from the cartridge. The combination of the dispenser and the cartridge is commonly referred to as the dispenser. Conventional AOS
In the dispensing device, two different means, one passive and the other active, are provided for delivering the product to the conveyor belt. Passive and active release systems for AOS differ from each other in the action exerted on the product by the release mechanism. Active systems usually differ from passive systems in that these active systems comprise means for forcibly ejecting product from the dispenser cartridge.

For example, gravity-based passive
e) A product release system is shown in FIGS. 5A and 5B of US Pat. No. 566,530. The passive system includes a dispensing gate at the end of the product cartridge and a stop gate located within the cartridge at least one product length from the dispensing gate.
The two gates are configured such that one is closed while the other is open and vice versa so that the products in the cartridge can be dispensed one by one. When the dispensing gate opens,
The product at the bottom of the stack is released. When the stop gate is opened, the next product is advanced in the cartridge to the position where it will be released the next time the dispensing gate is opened and lowered. This passive system is advantageous because it uses gravity to load the product released by the dispensing gate onto the lower conveyor without the use of a forced ejector.

An example of a conventional active lever release system is shown in FIGS. 5-7 of US Pat. No. 4,518,302, invented by Knapp. The lever is positioned to rotate about an axis such that one end of the lever is adjacent to the edge of the bottom product in the cartridge. An actuator coupled to the lever causes the lever to rotate about an axis and eject the product from the cartridge by the lever end adjacent the product. This active system is a passive system in that it uses a lever as an ejector or kicker to exert a force on the edge of the lower product to eject the product from the dispensing cartridge to the lower conveyor. Is different from

Many conventional passive and active delivery systems and mechanisms each have some drawbacks that make continuous use undesirable. Actuators (solenoid, hydraulic, pneumatic, etc.) and cooperating mechanisms, for example, depending on the configuration of the discharge system, occupy considerable space in the system, especially in the downstream conveyor direction. This is
Given the space required for additional product cartridges in the expanded system, the inefficient actuators and mechanisms for existing dispensers in the matrix occupy the system's ability to provide a limited fixed length conveyor. It has a negative impact on the potential for expansion.

An additional drawback of conventional passive and active dispensing systems is that the dispensed product is damaged as it is ejected from the cartridge and impacts the conveyor moving beneath. is there. A passive system rides on a conveyor that freely falls vertically and moves horizontally.
In active systems, the product is often discharged downward, typically in the opposite direction of the conveyor flow or downward across the conveyor flow. In both passive and active systems, heavy collisions between the moving conveyor and the product have been found to be a significant factor in causing the product to stick out of the package and causing damage to the product and its packaging.

Furthermore, conventional discharge systems have been found to have inherent limitations in their ability to handle products of different sizes and shapes. In early passive systems,
The friction between the product and the dispenser stop gate is used to hold the product during release of the bottom product. That is, a flat or thin package does not provide a sufficient surface to the stop gate to hold the product in the cartridge when the thin edges of the package are stacked flat, so that the package is not flat in the dispenser and not vertically. Must be stacked in the direction. In this case, the number of products that can be put in the cartridge is reduced, and frequent refilling of the products is required. Further improper stacking may result in the discharge of two or more products due to the actuation of the dispenser shown in FIG.

Accordingly, there is a need for an improved means of ejecting product from a product cartridge onto a moving conveyor belt of an automatic ordering system having multiple product dispensing devices. In order to maximize the number of dispensers that can be located along the longitudinal length of the conveyor, the actuating mechanism and the dispenser (displacer) should be arranged so that the dispensers adjacent to each other in the matrix are closer together. It should be as thin as possible in the vertical direction so that it can be stacked. In addition, effective and reliable means should be provided to ensure minimal damage to the product or packaging. Finally, adjustable means must be provided to handle products of various sizes and shapes.

[0014]

SUMMARY OF THE INVENTION To overcome the limitations of conventional passive and active release systems, the present invention is an improvement that can be used in various types, sizes and shapes of product and dispenser constructions. To provide a controlled active release mechanism. According to a broad aspect of the active product release mechanism of the present invention, the release mechanism comprises a pneumatically actuated flexible release belt disposed in a pair of substantially L-shaped guide tracks. The cartridge used in the ejection mechanism of the present invention holds the product overlap in a position between the two guide tracks so that the center of the lowest product of this overlap is flush with the base of the L-shaped track. . Pneumatic actuation moves the discharge belt through an L-shaped track to discharge the bottom product from the cartridge.

The active product ejection mechanism according to the present invention is small and concise, unlike conventional passive or active product ejection systems, in which adjacent dispensers (each consisting of a cartridge and a dispense mechanism) are placed in a dispenser matrix. Can be stacked more closely. In such a discharge system, more dispensers can be longitudinally positioned on a length of collection conveyor belt to increase the capacity of the AOS. The working path of the discharge belt is adjusted by adjusting the position of the bottom product in the cartridge. In this way, the dispensing device can handle products of various sizes and shapes. In addition, the cartridge and the flexible discharge mechanism (dispensing device) are oriented at a compound angle with respect to the conveyor belt to facilitate re-feeding of the product and minimize the risk of product damage associated with discharge.

The advantages of the flexible release mechanism and cartridge of the present invention are described in detail below with reference to the accompanying drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows an automatic ordering system [autom] having a known dispenser matrix structure and product delivery structure.
attended ordering system] (AO
S) 101 is a perspective view. Above the collection conveyor belt 103 of the automated ordering system 101, a plurality of product dispensers 105 of different shapes and sizes are placed to accommodate corresponding different types, sizes and shapes of products. Each product dispenser 105 comprises a product cartridge (not shown) and a dispensing mechanism (not shown). The separate product dispensers 105 lean against each other and with respect to the collection conveyor belt 103 at a 25 ° angle from the up and down direction to the outward (sideways) conveyor direction. is there. Tilting the product dispenser 105 laterally in this manner enhances the operation of the automatic ordering system 101 by facilitating manual product refeeding of the product dispenser.

The collection conveyor belt 103 is a "order zone" that represents a transport order or a portion of a transport order.
And a “buffer area” that separates adjacent order areas from each other. The longitudinal dimension of the ordering area is practically determined by the system control computer according to the total or partial shipping instructions that the automated ordering system 101 responds to. A
In the OS, the central control computer, when each area moves to the downstream side as the collecting conveyor belt 103 moves,
Track the location of the order area in real time. As the ordering area moves beneath the product dispenser that stores the ordered product, the computer causes a dispensing mechanism (not shown) for the product dispenser to place the correct number of products for the order in the ordering area. To release. The buffer area between each order area minimizes the risk of untimely mixing of products from adjacent order areas of different transport orders.

The end of the AOS collection conveyor belt 103 delivers the dispensed product in the order area onto a transfer conveyor belt 113 which acts as a transfer area between the collection conveyor belt 103 and the indexing conveyor 115. The slider 117 is moved by the indexing conveyor 115.
The product is directed from the transfer conveyor belt 113 into a transport box 119 located below 17. If some of the ordered products are not included in the dispensed order, additional products must be manually picked up to complete the shipping order. When the order is completed, the shipping box 119 is sent to the shipping area and sent to the customer.

FIG. 2 shows a plan view of an AOS 200 according to the present invention. In FIG. 2, each separate dispenser, which includes a cartridge 400 and an ejector (not shown) within each matrix, is oriented at a compound angle with respect to the lower conveyor belt 201. is there. The idea of this compound angle of the dispenser is still clear from Figures 3 and 4. 3 and 4 show cross-sectional and vertical cross-sections of the automatic ordering system or AOS 200 of FIG. First, as shown in FIG. 3, the dispensing device having the cartridge 400 is laterally tilted at an angle of 25 ° away from the conveyor belt 201 with respect to the vertical direction. Such lateral tilting facilitates manual re-feeding of the AOS 200. Second, as shown in FIG. 4, a dispensing device or cartridge 400.
Is 30 ° downstream from the conveyor belt
Is tilted at an angle (see also FIGS. 9 and 10).

Tilting in the longitudinal direction thus serves to direct the discharge mechanism (not shown in FIGS. 3 and 4 but shown in FIGS. 5, 9 and 10) and the dispensing device downstream. .
In this way, effective operation of the present system of a plurality of methods is facilitated. First, the vertical tilt allows the dispenser to dispense product from the cartridge below the vertically adjacent cartridge in the dispenser matrix to provide a reasonable space along the conveyor belt. Second, the vertical tilt allows the product to be discharged with the flow of the lower conveyor belt 201. In this case, the number of acute-angled impacts between the discharged product (FIG. 2C) and the conveyor belt 201 causing damage to the product and its packaging is minimized. Furthermore, the release of product from the conveyor flow minimized the risk of release product from the designated order area (Fig. 2).

The use of compound angles as in the present invention also provides several additional advantages. First, the use of a compound angle with the L-shaped cartridge 400 (see FIG. 7) forms a "toe" that effectively maintains product overlap alignment within the dispenser due to the compound angle and the L-shape, thus providing a dispenser Operation and recharging are made easier. This makes it easier for the operator to reload the dispenser, as the product only needs to be gravity loaded into the product to serve to align the product internally. Conventional upright U-shaped cartridges have been difficult to load because they have two side edges against which the loaded product strikes. FIG. 5 shows a perspective view of a flexible ejection mechanism 300 that occupies a substantially smaller longitudinal space in the AOS than conventional ejection systems. Flexible release mechanism 300
Thus, adjacent dispensers within the AOS matrix can be more closely stacked, and more dispensers can be included in the AOS without increasing the length of the AOS collection conveyor belt. With this increase in capacity obtained without a corresponding increase in conveyor length, more types of products can be AO
Can be included in S. With the increasing volume and variety of products, the manual removal of other products becomes less necessary.

The flexible release mechanism 300 according to the present invention.
Comprises a pneumatically actuated flexible discharge belt 301 disposed in a pair of substantially "L" shaped guide tracks 303L (left) and 303R (right) facing each other. Each L
The character-shaped tracks 303 are parallel to each other and the flexible discharge belt 3
01 is provided with an upper guide 305 and a lower guide 307 that are separated by a sufficiently large distance so that they can move freely inside. The guide track 303 effectively guides the vertical movement of the flexible discharge belt 301 and converts it into horizontal movement to discharge the product from the product cartridge as described below.

Each upper guide 305 is integrally constructed by a vertical arm 305a and a horizontal arm 305b joined by an oblique interconnection member 305c. Each lower guide 307 is integrally configured by a vertical arm 307a and a horizontal arm 307b joined by a curved interconnection member 307c. The upper and lower guides 305 and 307 are preferably made of a slightly flexible metal or metal alloy such as aluminum. The guides 305 and 307 are shown as having a substantially rectangular cross section, but needless to say this is not the case.

A lower guide vertical arm 307a for each guide track 303 is attached to the emitter mounting plate 309 by welding or other suitable means. L-shaped guide track 3
At one end 311 of 03, a spacer 313 is welded or otherwise secured between the horizontal arms 305b, 307b of the upper and lower guides, between which the release belt 3 is attached.
It is arranged to keep a sufficient distance that 01 can move. The upper and lower guides 305 and 307 are integrally formed to form the spacer 31.
Of course, the need for 3 may be eliminated. The vertical arm 305a of the upper guide is removably fixed to these by a spacer (not shown) and a nut 315 at a distance from the vertical arm 307a and the mounting plate 309. When the nut 315 is removed, the upper guide 3
05 allows the flexible discharge belt 301, which has been moved in a direction away from the lower guide 307, to be removed from the guide track 303 for maintenance or replacement.

An L-shaped guide track 3 formed by an oblique interconnection member 305c and a curved interconnection member 307c.
The three rollers 317 located in the curved portion of No. 03 are arranged in a triangular shape, and by bending the flexible discharge belt 301 so as to match the L-shape of the guide track 303, the vertical direction of the flexible discharge belt 301. Help to replace movement with horizontal movement. First roller 317a
And the second roller 317b are arranged on the left and right guide tracks 3 respectively.
Vertical arm 307a extending between 03L and 303R
And rotatably attached to the horizontal arm 307b. Similarly, the third roller 317c is connected to the left and right guide tracks 3
Diagonal interconnection member 30 extending between 03L and 303R
It is rotatably attached to 5c. Flexible release belt 3
When 01 is placed in the guide track 303, the flexible release belt will move to the first and second rollers 317a, 317b.
And the lower side of the third roller 317c. Each roller 317 reduces friction in the curved portion of the L-shaped guide 303 and determines the direction of translational movement of the belt from the vertical direction to the horizontal direction.

The flexible release belt 301, as shown in FIGS. 5 and 6, is a substantially rectangular flat flexible member which is preferably formed of a plastic material or other suitable flexible material. An actuator mounting block 321 is attached to the upper surface of the upper belt at the working end 319 of the flexible discharge belt 301. Flexible release belt 3
At impact end 323 of 01, impact block 325 is attached to the underside of the belt (as shown). Attaching the impact block 325 to the upper surface means that the impact block 325
This is not preferable because it interferes with the overlapping of products as the flexible discharge belt 301 operates. To the actuator mounting block 321, an actuating arm 327 coupled to a bidirectional pneumatic actuator 329 is coupled.

FIG. 5 also illustrates the operation of the flexible release mechanism 300. Pneumatic actuator 329 has pin 33
It is removably attached to the attachment plate 309 by 1. Flexible Release Belt 30 of Flexible Release Mechanism 300
In the rest state, 1 is oriented substantially vertically in the vicinity of the mounting plate 309, but the belt portion at the impact end 323 is bent horizontally by the rollers 317. The arm 327 causes the pneumatic actuator to move the flexible discharge belt 301, which is pushed downwardly against the actuator mounting block 321, from the rest state downward in the vertical direction into the guide track 303. Flexible release belt 3
01 is pushed by the arm 327 in the L-shaped guide path 303 through the curved portion, the roller 317 arranged in a triangle shape is pressed.
Sets the flexible discharge belt 301 to bend and conform to the L-shape, converting the up-and-down motion produced by the pneumatic actuator 329 into a horizontal motion for use in ejecting product from the cartridge. The pneumatic actuation force is then reversed to return the flexible release belt 301 to its rest position.

7 and 8 are a perspective view and an opposite side view, respectively, of a product cartridge 400 for use in the flexible ejection mechanism 300 (FIG. 5) to form a dispensing device.
The product cartridge 400 has a substantially L-shaped cross section and is composed of a base wall 401 and a side wall 403 made of a rigid lightweight plastic material or other suitable material. A grip 405 is provided on the top of the base wall 401 to allow an operator to carry or remove the dispenser or cartridge 400 when attached to the AOS 200 (FIG. 2). With the cartridge 400 as shown, the remote reloading of products can be easily done without disturbing the operation of the AOS 200.

At the bottom of the base wall 401, a product shelf 407, on which product stacks rest, is adjustably attached to the cartridge 400. Adjustable shelves 407 can actuate flexible ejection mechanism 300 (FIG. 5) for a variety of product geometries and are removably attached to cartridge 400 via rod 406 (shown only in FIG. 8). There is.
The use of the adjustable cartridge 400 provides advantages over conventional systems in that the dispensing mechanism 300 (FIG. 3A) does not require adjustment to handle products of various sizes and shapes.

The side wall 403 is mounted at its edge perpendicular to the base wall 401 to form a fold line 408. Within the fold line 408, the product overlaps when the cartridge 400 is oriented in a proper angle to release the product (see FIG. 2). The side wall 403 ends prior to the end of the base wall 401 and the slot 409 through which the emitted product passes.
(See FIG. 2B) is formed on shelf 407. In this configuration, the lower end 411 of the side wall 403 acts as a rigid front stop 413 that prevents additional product from being discharged other than the lowest product in the product stack.

Adjacent to the rigid front stop 413, an adjustable plastic front stop 414 is mounted on the side wall 403 to cover the slot 409. The flexible front stop 414 can be adjusted by the amount of the groove hole covered by the stop 414 with the stop 414 slot 415 and set screw 417 (see also FIG. 2B). Hole 4
Covering 09, the flexible front stop 414 prevents the bottom product from sliding off the cartridge 400 or from being inadvertently released from the cartridge 400. The cartridge 400 further comprises an adjustable rear stop 419 attached to the base wall 401 at the end of the cartridge adjacent the adjustable product shelf 407 to retract the product just above the bottom product by the ejection process as described below. It is intended to prevent movement and return of the ejection mechanism to the rest position.

A release process utilizing the flexible release mechanism 300 (FIG. 5) of the present invention will now be described with reference to FIGS. 7, 9 and 10. As is apparent in FIGS. 9 and 10, the cartridge 400 of FIG. 7 is oriented between a pair of L-shaped tracks 303, and the product shelf 407 has an L-shaped track and thus substantially the path of the belt 301 during the ejection process. Bottom product 500a
Adjust so that it is located along the center line of. In such an orientation, the flexible release belt 301 is the bottom product 500.
It is positioned so as to hit a most effectively at its approximate center of gravity.

In the preferred embodiment, the product in the cartridge 400 is oriented so that the flexible release belt 301 strikes the edge along the longest dimension of the product. First, the longest dimension of a product is almost always not the edge of the product. That is, when the product is hit, the end of the package opens due to the impact force so that the product does not stick out of the package. In addition, the lateral discharge of the longest dimension distributes the impact force over a larger area, minimizing the risk of product damage.

Since the flexible discharge mechanism 300 and the cartridge 400 are inclined with respect to the vertical direction as shown (see FIGS. 2, 3 and 4), the overlap of the product 500 is advantageous on the fold 408 of the cartridge. Also, the rigid and flexible front stops 413, 414 serve to prevent individual product stacks from falling from the dispenser. When energizing the pneumatic actuator, the flexible release belt 301 moves from a rest position adjacent to the mounting support 309 near the bend of the L-shaped guide track 303 and strikes the edge of the bottom product 500a to cartridge the product. Four
Release from 00. When the product 500a is released, the flexible front stop 404 bends through the product and propels it downstream to the lower moving conveyor belt 201. The downstream release minimizes the risk of product damage by reducing the risk of sharp strikes against the AOS 200. This release scheme reduces the risk of dispensed product rolling on the surface of conveyor belt 200 and diverting from the intended order area. When the flexible discharge belt 301 returns to the rest position next to the discharge of the lowermost product 500a,
The flexible release belt may be used, for example, for the next product 500b by friction with the product surface or contact with the impact block 325.
Grab The rear stop 419 allows the next product 500b to
When captured by the flexible release belt 301, it prevents the belt from moving backward as it retracts, maintaining proper product overlap in the cartridge 400. The rear stop 419 is attached to the base wall 401 with screws,
Position adjustments can be made to accommodate products of different sizes and shapes.

Further, as shown in FIGS. 9 and 10, the low position product detector 502 includes a photoelectric switch 503 and a reflecting mirror 505. The photoelectric switch 503 is the infrared beam 5
07 is directed to the reflecting mirror 505 through a groove hole 509 cut out in the base wall 403 of the cartridge 400. When the infrared beam 507 passes through the slot 509, the infrared beam is reflected by the reflecting mirror 505 and the photoelectric switch 50
3 is detected. A signal is then output indicating that the cartridge 400 is low on product. This signal alerts the operator of the AOS 200, refills the cartridge 400, or replaces the cartridge, and adjusts a central control computer (not shown) to identify a particular pre-selected number of products after release. Stop the dispensing device. However, if the cartridge 400 is filled to the extent that the product covers the slot 509,
The light beam is reflected from the mirror 505 and reflected by the photoelectric switch 503.
Prevented from returning to. That is, the switch 503 sends a signal to the operator that the dispensing device 400 contains sufficient product and in this case no refilling is required.

Although the present invention has been described in detail with reference to its preferred embodiments, it goes without saying that the present invention can be modified in various ways without departing from the spirit thereof.
