Description

Technical Field

[0001] One aspect of the present invention relates to a cart with a weighing function.

Background Art

[0002] A cart with a weighing function equipped with a weight weighing function is known. In such a cart with a weighing function, a plurality of weighing units are arranged on the cart, and containers for each store are placed on those weighing units. In the picking cart shown in Patent Document 1, the mounting surface of the weighing unit is inclined such that the front side is low and the back side is high. Therefore, when a container is placed on the mounting surface, there is a risk that the container on the weighing unit on the back side will shift and fall to the front side. In the picking cart shown in Patent Document 1, a partition member for preventing such a shift and fall is attached to the weighing unit on the back side. On the other hand, there is a demand to place and weigh one large container across a plurality of weighing units. For this reason, in the picking cart of Patent Document 1, when a container is placed across the front and rear weighing units, the partition member is configured to retract from the mounting surface by falling down.

Summary of the Invention

Problems to be Solved by the Invention

[0004] However, the partition member of Patent Document 1 is configured to fall in the direction in which the container shifts and falls. For this reason, when the weight of the articles in the container increases, the partition member cannot support the container and topples over. When different containers are placed on the weighing unit on the back side and the weighing unit on the front side, due to the above reason, the container placed on the weighing unit on the back side shifts and falls and contacts the container placed on the weighing unit on the front side, making it impossible to accurately weigh at each weighing unit.

[0005] Therefore, an object of one aspect of the present invention is to provide a cart with a weighing function that can prevent a container from slipping off a placement surface.

Means for Solving the Problems

[0006] (1) The cart with a weighing function according to one aspect of the present invention is a cart with a weighing function for placing goods contained in a container and being transported by an operator, and has a first placement surface inclined with respect to the horizontal direction, and a first weighing unit for acquiring the weight of the container placed on the first placement surface; a second weighing unit that is disposed adjacent to the first weighing unit and has a second placement surface formed at a position lower than the first placement surface on the same plane as the first placement surface, and for acquiring the weight of the container placed on the second placement surface; and a partition member that is disposed between the first placement surface and the second placement surface and restricts the movement of the container from the first placement surface toward the second placement surface. The partition member is attached as a tare of the first weighing unit. When the container is placed across the first placement surface and the second placement surface, the partition member is configured to be pushed down by the container and to fall from a first state in which it restricts the movement of the container to a second state in which it falls toward the side where the first placement surface is disposed.

[0007] In the cart with a weighing function having this configuration, the partition member disposed between the first placement surface and the second placement surface is configured to change from the first state to the second state by falling toward the side where the first placement surface is disposed. Therefore, even if the weight of the goods in the container becomes relatively heavy, the partition member does not fall toward the side where the second placement surface is disposed and can continue to support the container. As a result, it is possible to prevent the container from slipping off the placement surface regardless of the weight of the container.

[0008] (2) In the cart with a weighing function described in (1) above, the partition member is configured to protrude from the first placement surface in the first state, and may lock a container that is about to move from the first placement surface toward the second placement surface. In this configuration, since the partition member firmly locks the container that is about to move from the first placement surface toward the second placement surface, it is possible to prevent the container from slipping off the first placement surface.

[0009] (3) In the cart with a weighing function described in (1) or (2) above, the partition member may stand upright in the vertical direction in the first state. In this configuration, compared with the configuration in which the partition member stands upright in the first state in a direction perpendicular to the inclined surface, the amount of movement (rotation amount) of the partition member when tilting from the first state to the second state can be reduced. Thereby, when placing a container across the first placement surface and the second placement surface, the partition member can be configured to be easily tilted.

[0010] (4) In the cart with a weighing function described in any one of (1) to (3) above, the partition member may have a portion extending in the width direction that is perpendicular to both the direction in which the first placement surface is inclined and the direction perpendicular to the first placement surface. In this configuration, since the contact area between the partition member and the container when the partition member supports the container can be increased, the container can be supported more stably.

[0011] (5) In the cart with a weighing function described in any one of (1) to (4) above, the installation portions where the first weighing portion and the second weighing portion are installed are arranged in at least two upper and lower stages, and the inclination angles of the first placement surface of the first weighing portion and the second placement surface of the second weighing portion installed on the upper first installation portion may be larger than the inclination angles of the first placement surface of the first weighing portion and the second placement surface of the second weighing portion installed on the lower second installation portion. In this configuration, it is possible to set the inclination angles of the first placement surface and the second placement surface according to the posture of the operator when placing or removing the container. Thereby, the workability during picking by the operator can be improved.

Advantages of the Invention

[0012] According to one aspect of the present invention, it is possible to prevent the container from slipping off the placement surface.

Embodiments for Carrying Out the Invention

[0014] Hereinafter, a picking cart (cart with a weighing function) 1 according to an embodiment will be described with reference to the drawings. In the description of the drawings, the same reference numerals are given to the same elements, and redundant descriptions are omitted. In this specification, for the sake of convenience of explanation, "front", "rear", "left", "right", "up", and "down" directions may be used as viewed from the posture in which an operator moves the picking cart 1 as shown in FIG. 1.

[0015] The picking cart 1 according to an embodiment is installed in a logistics environment such as inside a distribution center, and is used for collecting goods to be delivered to a plurality of stores. The picking cart 1 places the goods stored in the container C and is transported by an operator. The picking cart 1 can transmit and receive information to and from a server device or the like, for example, by wireless communication via an access point.

[0016] The server device has a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), etc. The server device stores, for example, order information regarding ordered products of each store requested from a plurality of stores. In the collection area within a facility such as a distribution center, the server device manages product information of all products stored in product shelves, location information on which product shelf each product is stored in, information on which aisle each product shelf faces, etc.

[0017] As shown in FIGS. 1 and 2, the picking cart 1 includes a frame 2, a handle 3, wheels 4, a stopper 5, a cushion bumper 6, a completion button 10, a display monitor 11, a label printer 12, a scanner 13, a communication unit 14, a battery 15, a controller 16, a first weighing unit 40, a second weighing unit 50, and a partition unit 70.

[0018] The frame 2 supports the handle 3, the wheels 4, the stopper 5, the cushion bumper 6, the completion button 10, the display monitor 11, the label printer 12, the scanner 13, the communication unit 14, the battery 15, the controller 16, the first weighing unit 40, and the second weighing unit 50. The frame 2 is formed of, for example, a cylindrical or rectangular pipe member.

[0019] The handle 3 is a part that is gripped and pushed by the operator's hand. The wheels 4 roll on the floor surface F. Six wheels 4 are arranged at the lower part of the frame 2. The stopper 5 is a device for fixing the picking cart 1 to the floor surface F. The stopper 5 has an operating member 5A that is operated by the operator's foot. The operator can press the stopper 5 against the floor surface F by stepping on the operating member 5A. The operator can release the state of the stopper 5 pressed against the floor surface F by stepping on the operating member 5A again. The cushion bumper 6 is a rubber member having elasticity and functions as a shock absorber when colliding with another picking cart 1 or equipment arranged in the distribution center, and as a safety measure when colliding with an operator or the like.

[0020] The display monitor 11 is constituted by a touch panel. The display monitor 11 displays the type of the item to be input and the number of items to be input (picking number). Further, the display monitor 11 constitutes an operation part for receiving an input operation. The completion button 10 is a button to be pressed when the items of the input target type and number displayed on the display monitor 11 are taken out from the goods shelf and the taken-out items are put into the container C designated by the display monitor 11.

[0021] The label printer 12 issues a shipping label to be attached to the container C. The scanner 13 is a device for reading a product code such as a barcode of the item to be input. The communication unit 14 performs wireless communication with the server device via an access point. The battery 15 supplies power to the display monitor 11, label printer 12, scanner 13, communication unit 14, and controller 16 mounted on the picking cart 1.

[0022] The controller 16 has a CPU, ROM, RAM, etc. The controller 16 controls each part of the picking cart 1. Signals from the first measuring unit 40, second measuring unit 50, display monitor 11, label printer 12, scanner 13, and communication unit 14 are input to the controller 16.

[0023] The controller 16 causes the display monitor 11 to display the type and the number of items to be put in (picking number), and also displays the container C into which the item to be put in should be put. The controller 16 calculates the quantity of the item to be put in that has been put into the container C based on the weighing information transmitted from the first weighing unit 40 and the second weighing unit 50, and determines whether the operator has put in the correct item to be put in the correct number into the container C based on the barcode information transmitted from the scanner 13. The controller 16 causes the display monitor 11 to display the determination result.

[0024] In the picking cart 1 of the present embodiment, a first installation part P1 and a second installation part P2 where the first weighing unit 40 and the second weighing unit 50 are installed are arranged in upper and lower two stages. The first installation part P1 is arranged at a position higher than the second installation part P2. The first weighing unit 40 and the second weighing unit 50 are arranged in the first installation part P1. The first weighing unit 40 has a first placement surface 41 inclined with respect to the horizontal direction. The first weighing unit 40 acquires the weight of the container C placed on the first placement surface 41. The weighing value acquired by the first weighing unit 40 is input to the controller 16 and the weight of the container C is stored as tare weight.

[0025] The second weighing unit 50 is arranged adjacent to the first weighing unit 40. When viewed from the posture in which the operator moves the picking cart 1, the second weighing unit 50 is arranged in front of the first weighing unit 40. The second weighing unit 50 has a second placement surface 51 formed at a position lower than the first placement surface 41 on the same plane PL as the first placement surface 41 as shown in FIGS. 3(A) and 3(B). In other words, the second placement surface 51 is arranged in front of the first placement surface 41 on the plane PL that slopes downward toward the front side (toward the operator side when the operator holds the handle 3). The second weighing unit 50 acquires the weight of the container C placed on the second placement surface 51. The weighing value acquired by the second weighing unit 50 is input to the controller 16 and the weight of the container C is stored as tare weight.

[0026] In this embodiment, as shown in FIG. 2, two first measuring units 40, 40 and two second measuring units 50, 50 are arranged in the first installation part P1. When the first measuring unit 40 and the second measuring unit 50 are taken as a set of units, two sets of units are arranged in the first installation part P1. Further, in the second installation part P2 of this embodiment, two first measuring units 40, 40 and two second measuring units 50, 50 are arranged in the same manner as in the first installation part P1. Two sets of units are arranged in the second installation part P2 in the same manner as in the first installation part P1.

[0027] The inclination angle α1 (for example, 7 to 9°, preferably about 8°) of the first placement surface 41 of the first measuring unit 40 and the second placement surface 51 of the second measuring unit 50 installed in the upper first installation part P1 is larger than the inclination angle α2 (for example, 4 to 6°, preferably about 5°) of the first placement surface 41 of the first measuring unit 40 and the second placement surface 51 of the second measuring unit 50 installed in the lower second installation part P2.

[0028] Next, the details of the first measuring unit 40 will be described. As shown in FIGS. 3(A) and 3(B), the first measuring unit 40 includes a first placement surface 41, a first placement surface support member 45, a second support member 47B, a first weight sensor 49, and a first support member 47A.

[0029] The first placement surface 41 is a part where the container C is placed and is formed by a flat plate member. The first placement surface 41 is arranged to be inclined with respect to the horizontal plane. The inclination angle α1 of the first placement surface 41 with respect to the horizontal plane is, for example, 7 to 9°.

[0030] The first placement surface support member 45 is a member that supports the first placement surface 41 from below and is supported by the second support member 47B. The first placement surface support member 45 has a pair of side surface portions 45A, 45A, a rear surface portion 45B, and a front surface portion 45C. The pair of side surface portions 45A, 45A, the rear surface portion 45B, and the front surface portion 45C are plate-like members. The upper ends of the pair of side surface portions 45A, 45A are inclined upward from the front side toward the rear side. The upper ends of the pair of side surface portions 45A, 45A are portions that support the first placement surface 41 from below. The upper end of the rear surface portion 45B is a portion that supports the first placement surface 41 from below. The upper end of the front surface portion 45C is a portion that supports the first placement surface 41 from below. The vertical dimension (height) of the rear surface portion 45B is higher than the vertical dimension (height) of the front surface portion 45C. The first placement surface 41 is supported from below by such a first placement surface support member 45, and is arranged such that the inclination angle α1 with respect to the horizontal plane is, for example, 7 to 9°.

[0031] The second support member 47B supports the first placement surface support member 45 from below. The second support member 47B is supported by the first weight sensor 49. The second support member 47B is formed by a frame-shaped member. A partition unit 70 is attached to the second support member 47B. The partition unit 70 will be described in detail later. The first weight sensor 49 is a load cell type sensor. The first weight sensor 49 detects the load acting on the second support member 47B via the first placement surface 41 and the load acting on the second support member 47B via the partition unit 70. The measured value obtained by the first weight sensor 49 is input to the controller 16. The first support member 47A is fixed to the frame 2 and supports the first weight sensor 49 from below.

[0032] Next, the details of the second weighing unit 50 will be described. The second weighing unit 50 includes a second placement surface 51, a second placement surface support member 55, a fourth support member 57B, a second weight sensor 59, and a third support member 57A.

[0033] The second placement surface 51 is the portion on which the container C is placed and is formed by a flat plate member. The second placement surface 51 is arranged to be inclined with respect to the horizontal plane. The second placement surface 51 is arranged on the front side of the first placement surface 41 in the inclination direction of the first placement surface 41 and the second placement surface 51. The second placement surface 51 is formed at a position lower than the first placement surface 41 on the same plane PL1 as the first placement surface 41. The inclination angle α1 of the second placement surface 51 with respect to the horizontal plane is, for example, 7 to 9°, similar to the inclination angle α1 of the first placement surface 41 with respect to the horizontal plane.

[0034] The second placement surface support member 55 is a member that supports the second placement surface 51 from below and is supported by the fourth support member 57B. The second placement surface support member 55 has a pair of side portions 55A, 55A, a rear portion 55B, and a front portion 55C. The pair of side portions 55A, 55A, the rear portion 55B, and the front portion 55C are plate-like members. The upper ends of the pair of side portions 55A, 55A are inclined upward from the front side toward the rear side. The upper ends of the pair of side portions 55A, 55A are the portions that support the second placement surface 51 from below. The upper end of the rear portion 55B is the portion that supports the second placement surface 51 from below. The upper end of the front portion 55C is the portion that supports the second placement surface 51 from below. The vertical dimension (height) of the rear portion 55B is higher than the vertical dimension (height) of the front portion 55C. The second placement surface 51 is supported from below by such a second placement surface support member 55 so that the inclination angle α1 with respect to the horizontal plane is arranged to be 7 to 9°.

[0035] The fourth support member 57B supports the second mounting surface support member 55 from below. The fourth support member 57B is supported by the second weight sensor 59. The fourth support member 57B is formed by a frame-shaped member. A locking member 53 is attached to the fourth support member 57B. The locking member 53 locks the container C that tends to slip off the second mounting surface 51 at the lower end of the second mounting surface 51. The second weight sensor 59 is a load cell type sensor. The second weight sensor 59 detects the load acting on the fourth support member 57B via the second mounting surface 51 and the load acting on the fourth support member 57B via the locking member 53. The measured value obtained by the second weight sensor 59 is input to the controller 16. The third support member 57A is fixed to the frame 2 and supports the second weight sensor 59 from below.

[0036] As shown in FIGS. 3(A), 3(B) and 4, the partition unit 70 is disposed between the first mounting surface 41 and the second mounting surface 51 in the front-rear direction (the inclination direction of the first mounting surface 41 and the second mounting surface 51), and has a partition member 71 that restricts the movement of the container C from the first mounting surface 41 toward the second mounting surface 51. The partition unit 70 includes a mounting member 73A, a support member 73B, a rotating unit 77, a torsion spring 75, a base plate 79, and a partition member 71.

[0037] The partition unit 70 is attached as a tare of the first weighing unit 40. The attachment member 73A is attached to the front surface portion 45C which is a part of the first placement surface support member 45. The attachment member 73A extends forward in the horizontal direction from the front surface portion 45C. The support member 73B is attached so as to stand upright from the attachment member 73A. The rotating portion 77 is rotatably supported with respect to the support member 73B. A base plate 79 is attached to the rotating portion 77 via a connecting portion 77A. Two partition members 71, 71 are attached to the base plate 79. Each of the two partition members 71, 71 is formed in an inverted U shape when viewed from the front. Each of the two partition members 71, 71 has a portion extending in the width direction D (left - right direction) orthogonal to both the direction in which the first placement surface 41 is inclined and the direction orthogonal to the first placement surface 41.

[0038] When the rotating portion 77 is viewed from the right side in FIG. 1, it is biased by a torsion spring 75 to rotate counterclockwise. A regulating portion 77B that can contact the support member 73B is formed on the rotating portion 77. In a state where the rotating portion 77 is biased by the torsion spring 75 to rotate counterclockwise, contact of the regulating portion 77B with the support member 73B restricts the rotating portion 77 from rotating counterclockwise. In this way, the state in which the rotation of the rotating portion 77 counterclockwise is restricted is referred to as the first state S1 (see FIG. 3(A)).

[0039] In such a first state S1, the partition unit 70 has the base plate 79 horizontal and the partition members 71 standing upright in the vertical direction. At this time, the partition member 71 protrudes from the plane PL in which the first placement surface 41 and the second placement surface 51 are arranged, and locks the container C1 that attempts to move downward from the first placement surface 41 toward the second placement surface 51 as shown in FIG. 5(A). Note that the first placement surface 41 and the second placement surface 51 exist on the same plane PL.

[0040] There may be a case where a container C2 larger than the size of the container C1 shown in FIG. 5(A) is placed across the first placement surface 41 and the second placement surface 51 as shown in FIG. 5(B). Here, when the container C2 is placed across the first placement surface 41 and the second placement surface 51, the partition member 71 is pushed down by the container C2, and changes from the first state S1 that restricts the movement of the container C to the second state S2 where it falls toward the side where the first placement surface 41 is located. In the partition unit 70, when the partition member 71 is pushed down by the container C2, the rotating part 77 rotates clockwise. The rotating part 77 rotates until the partition member 71 does not protrude from the plane PL in which the first placement surface 41 and the second placement surface 51 are located.

[0041] When the partition member 71 is in the second state S2, based on the measured value by the first weighing unit 40 and the measured value by the second weighing unit 50, the weight of the container C2 placed across the first placement surface 41 and the second placement surface 51 can be obtained. The sum of the measured value by the first weighing unit 40 and the measured value by the second weighing unit 50 may be calculated, for example, when set to the summation mode by the operator, or may be calculated when it is detected by the sensor that the partition member 71 has entered the second state S2.

[0042] The operation and effect of the picking cart 1 in the above embodiment will be described. In the picking cart 1 of the above embodiment, the partition member 71 disposed between the first placement surface 41 and the second placement surface 51 is configured to change from the first state S1 to the second state S2 by falling toward the side where the first placement surface 41 is located. For this reason, even if the weight of the goods in the container C becomes relatively heavy, the partition member 71 does not fall toward the side where the second placement surface 51 is located, and the support of the container C can be continued. As a result, it is possible to prevent the container C placed on the first placement surface 41 and whose movement is restricted by the partition member 71 from slipping off the first placement surface 41 regardless of its weight.

[0043] In the picking cart 1 of the above embodiment, as shown in FIG. 5(A), in the first state S1, the partition member 71 is configured to protrude from the plane PL on which the first placement surface 41 and the second placement surface 51 are arranged, and locks the container C that attempts to move from the first placement surface 41 toward the second placement surface 51. Thereby, since the partition member 71 firmly locks the container C that attempts to move from the first placement surface 41 toward the second placement surface 51, it is possible to prevent the container C from deviating and falling from the first placement surface 41. More specifically, it is possible to prevent the container C from deviating and falling from the first placement surface 41 and coming into contact with the container C placed on the second placement surface 51 below the inclined direction of the first placement surface 41.

[0044] In the picking cart 1 of the above embodiment, in the first state S1, the partition member 71 stands upright in the vertical direction. Thereby, as shown in FIG. 6, compared with the configuration in which the partition member 71 stands upright in the direction orthogonal to the first placement surface 41 in the first state S1, the movement amount (rotation amount) of the partition member 71 when tilting from the first state S1 to the second state S2 can be reduced. Thereby, when placing the container C across the first placement surface 41 and the second placement surface 51, the partition member 71 can be configured to be easily tilted.

[0045] In the picking cart 1 of the above embodiment, the partition member 71 has a portion extending in the width direction D (see FIG. 2) orthogonal to both the direction in which the first placement surface 41 is inclined and the direction orthogonal to the first placement surface 41. In this configuration, since the contact area between the partition member 71 and the container C when the partition member 71 supports the container C can be increased, the container C can be supported more stably.

[0046] In the picking cart 1 of the above-described embodiment, the installation parts P1 and P2 where the first weighing part 40 and the second weighing part 50 are installed are arranged in at least two upper and lower stages, and the inclination angles of the first placement surface 41 of the first weighing part 40 and the second placement surface 51 of the second weighing part 50 installed on the upper first installation part P1 are larger than the inclination angles of the first placement surface 41 of the first weighing part 40 and the second placement surface 51 of the second weighing part 50 installed on the lower second installation part P2. Thereby, it becomes possible to adjust the inclination angles of the first placement surface 41 and the second placement surface 51 to the inclination angles according to the posture when the operator places or takes out the container C. Thereby, the workability at the time of picking by the operator can be improved.

[0047] As described above, one embodiment has been described, but one aspect of the present invention is not limited to the above-described embodiment. Various modifications are possible without departing from the spirit of the invention.

[0048] In the above-described embodiment, the partition member 71 formed in an inverted U shape when viewed from the front side has been described as an example, but the present invention is not limited to this. For example, the partition member 71 may be constituted only by a portion extending in the vertical direction when it is in the first state S1. As long as it has a shape that can lock the container C1 that protrudes upward from the first placement surface 41 and tends to deviate from the first placement surface 41, the shape, quantity, material, etc. are not particularly limited.

[0049] In the above-described embodiment and the above-described modification, the partition member 71 has been described by taking the example of standing upright in the vertical direction in the first state S1. However, as shown in FIG. 6, it may stand upright in a direction orthogonal to the first placement surface 41. Even in this case, the container C that tends to deviate from the first placement surface 41 can be locked.

[0050] In the above-described embodiment and the above-described modification, an example in which two first weighing parts 40 and two second weighing parts 50 are arranged in one installation part has been described, but at least one first weighing part 40 and one second weighing part 50 are sufficient, and the number of the first weighing part 40 and the second weighing part 50 is not particularly limited.

[0051] In the above-described embodiments and the above-described modification examples, an example in which the inclination directions of the first placement surface 41 and the second placement surface 51 are inclined downward from the rear side toward the front side has been described. However, they may be inclined upward from the rear side toward the front side, or may be inclined upward or downward from the right side toward the left side.

[0052] In the above-described embodiments and the above-described modification examples, an example in which the installation parts P1 and P2 where the first measuring part 40 and the second measuring part 50 are installed are arranged in upper and lower two stages has been described. However, they may be in one stage or three or more stages.
