DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Apparatus of this invention includes at checkout counter 20 having a receiver portion 22, an intermediate portion 24, and a discharge portion 26.
The receiver portion 22 is provided with a pair of spaced-apart shafts 30 and 32, each of which extends between side portions 34 of the receiver portion 22. Each of the side portions 34 has an arcuate director member 35 attached thereto and extending therefrom. A plurality of spaced-apart wheels 38, best shown in FIG. 4, are attached to each of the shafts 30 and 32. Belts 40 encompass the wheels 38 of the shafts 30 and 32, as each belt 40 is supported by a wheel 38 of the shaft 30 and a wheel 38 of the shaft 32. It is to be understood, however, that annular members, other than the belts 40 may be used, for example, chains, wheels, and the like.
A motor 42 shown diagrammatically in FIG. 1, is operably joined, by any suitable means, to the shaft 32 for rotation thereof. Thus, the motor 42, when energized, causes rotation of the wheels 38 and the belts 40, as illus'trated in FIG. 3.
The intermediate portion 24 of the checkout counter 20 is shown as being substantially flat, for sliding movement of articles from the receiver portion 22 to the discharge portion 26.
The discharge portion 26 of the checkout counter 20 includes a relatively wide conveyor belt 46 which is supported by spaced-apart shafts 50 and 52. FIG. 9 shows a roller 59 which is carried by the shaft 52 and which partially supports the conveyor belt 46. A motor 54, shown diagrammatically in FIG. 1, is operably connected by any suitable means, so the shaft 50 for rotation thereof and for rotative movement of the conveyor belt 46.
A plurality of partition members, herein shown as partition members 56 and 58, extend over the conveyor belt 46 and divide the conveyor belt 46 into a plurality I of sections, herein shown as sections 46a, 46b, and 46c.
At the end of the discharge portion 26 and adjacent the section 46a of the conveyor belt 46 is a wall 60, shown in FIGS. 1 and 2. In substantial alignment with the wall 60 and disposed between the partitions'56 and 58 and between the partition 58 and a side wall 69 is an inclined shelf 64, shown in FIGS. 10 and 12, which is attached to a support bar 66 by means of a connector 68. The uppermost part of the inclined shelf 64 is closely adjacent the belt 46. An arm 70 is pivotally connected by means of a pin 72 to a fixed bracket 74 which is attached to the partitions 56 and 58. A plate 78 is secured to a rotatable stem 80 which is carried by the pivotal arms 70 and extends therebetween. The plate 78 has flanges 82 attached thereto at opposite portions thereof. Thus, a structure comprising the elements 64, 66, 68, 69, 70, 72, 74, 78, and 80 is disposed between the partitions 56 and 58 and another such structure is disposed between the partitions 58 and the side wall 69, at the ends thereof.
Below the support bar 66 and below each plate 78 is a support element or bag holder which is pivotally carried by a pin 92. The support element 90 has a floor 94 and sides 96, secured thereto.
As best shown in FIG. 9, a pad 100 engages the support element 90. The pad 100 is attached to a rod 102 which has a collar 104 secured thereto. The rod 102 freely slidably extends through a bracket 110. A collar 111 is attached to the rod 102 below the bracket 110 and limits upward travel of the rod 102. A spring 112 encompasses the rod 102 and is disposed between the bracket 110 and the collar 104. Thus, the spring 112 resiliently urges the rod 102 and the support element 90 in a direction from the bracket 1 10. A rigid elongate abutment member 116 is also attached to the bracket 1 l and extends therefrom toward the support element 90.
A basket-cart 130 cooperates with the checkout counter 20. The basket-cart 130 has wheels 132 which support a lower rack 134. Struts 136 connect the lower rack 134 to an upper rack 140, which has side members 142 and a back member 144. A handle 145 is shown attached to the upper rack 140.
The bottom of the rack 140 has a solid section 148. A plurality of spaced-apart bars 146 are attached to the solid section 148 and extend forwardly thereof. The forward end of at least one of the bars 146 has an upwardly extending protuberance 149, as shown in FIGS. and 6. At the forward portion of the basket-cart 130 and attached to the side members 142 are holders 150, each of which is provided with a keyhole shaped opening 152 which has a narrow portion 154, which tenninates in a generally rectangular slot 156.
A shaft 160 extends between the holders 150 and has the ends thereof within the openings 152. Each end of the shaft 160 has a lug 162. The shaft 160 has attached thereto a gate 166. FIG. 1 shows that the gate 166 may include a sheet portion 167. It is to be understood that the gate 166 may be of wire, or may be solid, or have openings, and may be of any suitable material. The lower part of the gate 166 normally rests upon the forward part of the bars 146 and engages the upwardly extending protuberances 149 of the bars 146, as shown in FIG. 5.
OPERATION A customer places articles of merchandise within the basket-cart 130 and then moves the basket-cart 130 to the checkout counter to have the articles checked" by a checkout clerk 180 who uses a cash register 182 or the like. The checkout clerk 180 is positioned adjacent the intermediate portion 24 of the checkout counter 20 and may have control over the operation of the motor 42. The basket-cart 130 is moved to the receiver portion 22 of the checkout counter 20, and is received by the receiver portion 22 between the director members 35.
The spacing between the belts 40 is substantially equal to the thickness of the bars 146. Therefore, as the basket-cart 130 moves between the director members 35, the basket-cart 130 also moves between the side portions 34 of the receiver portion 22 of the checkout counter 20. The bars 146 become alternately positioned with the belts 40, as illustrated in FIGS. 4 and 14. Thus, the basket-cart 130 can be moved forwardly between the side portions 34 of the receiver portion 22 until the solid section 148 comes into contact with the belts 40.
As illustrated in FIGS. 3 and 15, the portions of the belts 40 between the wheels 38 are upwardly inclined. As the basket-cart 130 is moved forwardly between the side portions 34, the bars 146 move to intermeshed juxtaposition among the belts 40. The bars 146 become positioned at a lowerlevel than a portion of the belts 40. Thus, the belts 40 lift the gate 166 from the position thereof shown in FIG. 5 to the position thereof shown in FIG. 6. As illustrated, the belts 40 lift the gate 166 from engagement with the bars 146, above the protuberances 149. Thus, as the upper portions of the belts 40 move forwardly, the lower part of the gate 166 is moved forwardly, as illustrated in FIG. 6.
As the gate 166 is lifted and angularly moved upwardly, the shaft 160, positioned within the openings 152, is permitted to freely move upwardly, as shown in FIG. 6. Due to the fact that when the bars 146 and the belts 40 are intermeshed the belts 40 are positioned at a higher elevation than the bars 146, articles of merchandise are lifted from the bars 146 by the belts 40. Therefore, after the belts 40 cause the bottom part of the gate 166 to move forwardly, the articles of merchandise are moved forwardly upon the belts 40 to the intermediate portion 24 of the checkout counter 20.
In order to permit the articles of merchandise to freely move forward to the intermediate portion 24, without interference by the gate 166, the checkout clerk 180 may lift the forward part of the gate 166 and rotatively move the gate 166 until the gate 166 is inverted and vertically disposed, as illustrated in FIG. 7. Thus, the shaft is moved downwardly into the portion 154 of the opening 152 and the lug 162 moves into the slot 156 to retain the gate 166 in the inverted vertical position, as shown in solid lines in FIG. 8. Thus, the gate 166 remains in the inverted vertical position as articles of merchandise are moved forwardly upon the belts 40 from the bars 146, to the intermediate portion 24 of the checkout counter 20.
As each article of merchandise reaches the intermediate portion 24, the checkout clerk 180 manually engages the article with one hand and operates the cash register 182 with the other hand. The clerk 180 then manually moves the article of merchandise to one of the sections 46a, 46b, or 460 of the conveyor belt 46.
The motor 54 rotates the conveyor belt 46 so that the upper surface thereof moves away from the intermediate portion 24, as illustrated by an arrow 186 in FIG. 2.
If the article of merchandise is relatively heavy and- /or sturdy, as, for example, a can or box of merchandise, the article is moved by the checkout clerk to the 460 section of the conveyor belt 46. The article is then moved by the conveyor belt 46 to the inclined floor 64.
A paper bag or the like rests upon the support element or bag holder 90 and the floor 94. The flanges 82 of the plate 78 extend into the bag 170 and serve to keep the top of the bag 170 open. The flanges 82, with the plate 78, form a chute and serve to direct an article into the bag 170, as the article moves from the inclined shelf 64, to the plate 78. Thus, as illustrated in FIG. 2, each article moved by the checkout clerk to the section 460 of the conveyor belt 46 is automatically moved by the belt 46 to the inclined shelf 64, from whence the article falls to the plate 78 and is directed into the bag 170.
Light and/or delicate or breakable articles of merchandise are moved by the checkout clerk 180 to the section 46a of the conveyor belt 46. The section 460 moves each article toward the wall 60. From such position the articles may be manually and individually placed into a bag 170 which may be positioned upon a shelf 184, shown in FIGS. 1 and 2.
FIGS. 1 and 2 show no bag 170 or the like supported by the bag holder 90 at the end of the section 46b. Thus, preferably, the plate 78 is pivotally positioned as shown in FIG. 12. The plate 78 thus serves as a barrier to prevent movement of articles from the inclined shelf 64 which is at the end of the section 46b, The plate 78 may be readily pivotally moved from the position thereof shown in FIG. to the position thereof shown in FIG. 12. Such pivotal movement of the plate 78 is performed by pivotal movement of the arms 70 about the axis of the pin 72 and by pivotal movement of the plate 78 about the axis of the stem 80, as illustrated in FIG. 11.
Thus, it is understood that each plate 78 may be pivotally positioned as shown in FIG. 10 to form a chute or may be pivotally positioned as shown in FIG. 12 to form a barrier. When the plate 78 is in the position shown in FIG. 10, the flanges 82 thereof assist in maintaining the upper part of the bag 170 in an open positron.
As articles of merchandise move into a bag 170 which is supported by a bag holder 90, the weight of the articles causes the bag holder 90 to pivotally move downwardly, as illustrated in FIG. 9. The pivotal position of the bag holder 90 is determined by the spring 112. As the weight of articles increases within the bag 170 supported by the bag holder 90, the spring 112 permits the rod 102- to move downwardly as the rod 102 is forced downwardly by the weight of articles within the bag 170. Such downward movement of the rod 102 is against the resiliency of the spring 1 12. Thus, the bag 170 automatically becomes more vertically disposed as greater weight is disposed therewithin.
Thus, it is understood that apparatus of this invention provides means by which articles of merchandise are automatically removed from a basket-cart. The articles are then manually moved by a checkout clerk to selected sections of a conveyor belt. An article moved to each conveyor belt section is moved by the conveyor belt to a bagging position. If the plate 78 at the end of the section is pivotally disposed as shown in FIG. 10, the article falls into a bag. If the plate 78 is pivotally disposed as shown in FIG. 12, the article is prevented from movement from the checkout counter 20.
After all of the articles of merchandise within the basket-cart 130 have been moved therefrom, the checkout clerk 180 lifts the gate 166 from the vertical inverted position thereof shown in FIG. 8 and permits the gate 166 to rotatively move into the basket-cart as illustrated in FIG. 8, to again become positioned against the protuberances 149 and the bars 146.
Although the preferred embodiment of the device has been described, it will be understood that within the purview of this invention various changes may be made in the form, details, proportion and arrangement of parts, the combination thereof and mode of operation, which generally stated consist in a device capable of carrying out the objects set forth, as disclosed and defined in the appended claims.
