Description

  The present invention relates to a cart trolley pre-packing device of a type in which a driving tire is pressed by a spring force to the lower side of each of the right side surface and the left side surface of the cage cart and conveyed while being contacted and rotated. A driving state release mechanism is proposed.

  2. Description of the Related Art Conventionally, many carts for carrying a large number of small luggage are used. Such a cart is moved to a work position by being pushed by a human hand in order to take out or load a load. However, frequent movement of a large number of carts has a problem in terms of work efficiency due to the heavy burden of human labor.

  In consideration of such a problem, many conveyor systems that move a cart without depending on human effort have been proposed (see Patent Documents 1 to 3). Patent Documents 1 to 3 are all systems that carry a carriage on a conveyor having a drive chain, and propose a system that can easily retract the carriage from a conveyance line. In the systems of Patent Documents 1 to 3, the chain conveyor is divided to have a plurality of areas, and spacers are provided in the gaps between the chain conveyors to smoothly transfer the carriage.

  However, since the systems of Patent Documents 1 to 3 use a chain conveyor to transport the cart, it is necessary to dig a pit below the floor in order to make the conveyor transport surface and the floor surface (loading path) continuous. There was a problem that the degree of freedom was low and it could not be easily introduced into existing facilities. In addition, since a cart full of luggage is placed on the conveyor for transport, a large drive source is required, which increases the equipment cost. In addition, the spacer provided in the gap between the chain conveyors is likely to cause a certain level difference between the transport surface and the spacer due to an assembly error, and if the wheel of the carriage is not properly aligned, the wheel will make the level difference well. There was a problem that the carriage could not be overcome and the truck was clogged.

  In response to such a problem, the applicant does not place the cart on the chain conveyor for transport as in the prior art, but presses the drive tire with a spring force below each of the right and left sides of the cart. There has been proposed a cart stuffing device that can easily forward the cart with relatively small power by means of conveying the cart while rotating in contact (see Patent Document 4).

  The apparatus of Patent Document 4 is excellent in that the drive unit is provided on the conveyance surface, so that it is not necessary to dig a pit under the floor, and the floor surface and the conveyance surface can be easily continued.

  However, when such a cart stuffing device is adopted, the drive tires are designed to push and convey the lower side of the right and left sides of the cart, so that if the drive motor stops due to a failure or a power failure, etc. The car cart remains sandwiched between the left and right drive tires, and it is extremely difficult to remove the car cart from the device.

Patent No. 5107471 Patent No. 5107472 Japanese Patent No. 5173046 Japanese Patent Application No. 2015-29896

  Although an example of the cart stuffing device of the present invention will be described below with reference to the accompanying drawings, the present invention is not limited to these.

  As the cart used in the basket cart pre-packing device of the present invention, a substantially rectangular parallelepiped shape that can be piled up in order on a floor panel with wheels and moved by being pushed by a human hand is preferably used. can do. For example, as shown in FIG. 1, a floor panel 2 with wheels, a front panel 3, a rear panel 4, and two opposing right side panels 5, a left side panel (not shown) ), Which is also called a roll box, an easy container, or a pipe cargo depending on the product. The basket cart used in the present invention is preferably of a type having a front, rear and side width of 60 cm to 2 m and a height of 1 to 3 m. In addition, the cart used in the present invention preferably has a portion that can be pressed and contacted by the drive tire (a portion that can transmit the driving force) over the length of the side surface in the lower portion of both side surfaces. FIG. 1 also schematically shows a portion where the drive tire of the right side contact driving unit of the car cart of the present invention, which will be described later, is in contact with the lower side of the right side surface of the car cart.

  Next, a description will be given, based on FIG. 3, of a car cart front-packing device in which a drive unit for conveying the car cart described above is provided on the floor surface. FIG. 3 is a schematic plan view of an example of a cart stuffing apparatus according to the present invention. In the figure, reference numeral 1 denotes a cart, and an arrow indicates a traveling direction of the cart 1. Reference numeral 6 denotes a car cart right side contact drive unit, and 7 denotes a car cart left side contact drive unit, which constitute a drive unit for transporting the car cart. The car cart right side contact driving unit 6 and the car cart left side contact driving unit 7 are respectively installed on the right side and the left side of the transport path of the car cart 1 and are moved in the traveling direction on the right side and left side of the car cart, respectively. It has a drive tire 8 that transmits force.

  The drive tire 8 has a drive shaft in the vertical direction as shown in FIGS. 2 and 3 and is rotated by a drive motor 9 such as an electric motor as a drive source. As shown in FIG. 2, a plurality of drive tires 8 may be used by being stacked on the same drive shaft. In FIG. 1 and FIG. 2, the traveling surface of the drive tire 8 of the car cart right side contact driving unit 6 is a portion that can be pressed and contacted by the spring force of the spring pressing means 12 below the right side surface 5 of the car cart 1 (drive force transmission). Only the mode of being pressed so as to come into contact with the possible portion) is shown, but the traveling surface of the driving tire 8 of the car cart left side contact driving unit 7 on the opposite side is also the same as that of the left side surface of the car cart 1 at the same time. It is pressed so as to come into contact with the lower pressing contactable part (drive force transmitting part) by the spring force of the spring pressing means. At this time, the cage cart is in a state where both sides of the right side surface and the left side surface are sandwiched and pressed by the drive tire 8, and in this state, the drive tire 8 of the cage cart right side surface contact drive unit 6 rotates to the right, At the same time, when the drive tire 8 of the left side contact portion 7 of the car cart rotates counterclockwise, the car cart pressed by the two drive tires can be fed forward in the traveling direction of the transport path. In this way, the method of the present invention does not receive and transport the weight of the cart as it is like the chain conveyor system, but transmits the driving force by pressing both sides of the cart at the same time. The cart can be moved forward with small power.

  As shown in FIG. 3, the drive tire 8 of the car cart right side contact driving unit 6 and the drive tire 8 of the car cart left side drive unit 7 are on a straight line perpendicular to the traveling direction of the car cart with their running surfaces facing each other. And preferably present in pairs. The number of drive tire pairs depends on the distance of the transport path, but is preferably at least 2, more preferably at least 3, and even at least 4. Further, when a plurality of pairs of drive tires are provided, it is preferable that the pairs of drive tires are provided at a distance between drive shafts that is equal to or less than the length in the traveling direction of the side surface of the cart in the traveling direction of the transport path. As a result, at least one pair of driving tires can be stably pressed between the side surfaces of the cart and the driving force can be transmitted, and the forward movement of the cart in the traveling direction can be performed smoothly.

  As shown in FIG. 3, the basket cart front-packing device according to the present invention is provided with a photoelectric sensor 13 that detects the cage cart entering the device according to the present invention (specifically, blocking the linear light between 13). Is preferred. The photoelectric sensor 13 is preferably within 1 meter before the straight line connecting the respective drive shafts of the first drive tire pair of the first pair of drive tires (specifically, the straight line connecting 14 to each other) in the traveling direction of the cart, more preferably It is configured so as to detect that the tip of the cart is on a straight line 10 cm to 100 cm in front (specifically, a straight line connecting 13 to each other). Thus, by detecting in advance the cart that has entered the vehicle, it is possible to appropriately control the start / stop of the rotation of the drive tire that follows.

  The basket cart front-packing device of the present invention has a plurality of carts transported, and when each cart is sequentially stopped at a predetermined planned position at a predetermined longitudinal interval as shown in FIG. It is preferable to provide a photoelectric sensor 14 that senses that the tip of the cart is reached within 50 cm, more preferably 10 cm to 50 cm, in the traveling direction from the tip. The photoelectric sensor 14 is arranged in parallel with the front end of the transporting cart, and specifically, is configured to sense the cart that blocks the linear light between 14 as shown in FIG. The photoelectric sensor 14 described above senses the cart and acquires the position information of the cart. The position of the photoelectric sensor 14 is variable and is determined by the stop interval of the cart. The photoelectric sensor 14 serves as a start / stop switch for the drive tire. By appropriately controlling the start and stop of rotation of the drive tire by the photoelectric sensor 14, a plurality of carts can be moved smoothly while avoiding a collision between the carts.

  Next, an example of the control method of the basket cart front-packing device of the present invention will be illustrated with reference to FIGS. In addition, the cart stuffing apparatus shown in FIG. 5 is used, PH1 to PH5 in the figure indicate the photoelectric sensor described above, and Motor1 to Motor4 indicate the pair of driving tires described above. In addition, START and END in the control flow in FIGS. 6 to 9 mean start and end, respectively, and PH1 to PH5 ON and OFF mean that PH1 to PH5 are detected and no sense, respectively, and Motor1 to Motor4 are ON. , OFF means that the motors 1 to 4 are switched on and off, respectively, and N and Y mean “NO” and “YES”, respectively.

  FIG. 6 shows a control flow after the car cart enters the car cart pre-packing device and after PH1 is sensed until after PH2 is sensed, and FIG. 7 shows a control flow from after PH2 is sensed to after PH3 is sensed. FIG. 8 shows a control flow from sensing PH3 to sensing PH4, and FIG. 9 shows control flow from sensing PH4 to the end of the cart stuffing apparatus. The control flows shown in FIGS. 6 to 9 are merely examples, and other control flows can be employed depending on the purpose.

  Next, a mechanism of a connecting portion that can connect or disconnect the drive tire and the drive shaft of the drive motor of the basket cart pre-packing device of the present invention will be described with reference to FIGS. FIG. 10 is a schematic diagram of a part of the cart trolley pre-packing device according to the present invention as viewed from the rear when the drive tire and the drive shaft of the drive motor are connected to each other, and viewed from the corresponding side. A schematic diagram of the area near the drive motor is shown on the left. FIG. 11 is a schematic view of a portion near the drive motor in FIG. 10 as viewed from above. 12 is a view similar to FIG. 10 showing a state where the drive tire and the drive shaft of the drive motor are disconnected from each other, and FIG. 13 is a view where the drive tire and the drive shaft of the drive motor are connected to each other. It is the same figure as FIG. 10 which showed the state in the middle of changing to a connection cancellation | release state (FIG. 12) from a state (FIG. 10). In each figure, 1 is a car cart, 7 is a car cart left side contact drive unit, 8 is a drive tire, 9 is a drive motor, 10 is a drive shaft connecting portion of the drive motor, and 11 is a drive shaft connecting portion of the drive tire. , 12 is a spring pressing means, 15 is a lever, 16 is a lift guide, 17 is a lift plate, 18 is a lever rotation fulcrum, 19 is a lever end support shaft, and 20 is a lever end support bearing plate.

  In the apparatus of the present invention, as shown in FIGS. 10 to 13, the drive tire 8 and the drive motor 9 have a drive shaft in the same vertical direction, and the drive shaft connecting portion 10 of the drive motor 9 and the drive tire 8. The drive shaft connecting portions 11 can be connected to each other as shown in FIG. 10, or can be released from the connection as shown in FIG. FIG. 13 shows a state in which both the connecting portions 10 and 11 are in the process of shifting from the connected state of FIG. 10 to the disconnected state of FIG. When the two connecting portions 10 and 11 are connected to each other as shown in FIG. 10, the driving force of the drive motor 9 is effectively transmitted to the driving tire 8, but the connection between the connecting portions 10 and 11 is shown in FIG. When is released, the driving force of the driving motor 9 is not transmitted to the driving tire 8 at all. When the driving force is not transmitted, the driving tire 8 can freely rotate. Therefore, even when the drive motor 9 is stopped due to a failure, a power failure, etc., the car cart 1 can move the drive tire 8 freely by setting both the connecting portions 10 and 11 to the disconnected state as shown in FIG. Can be taken out easily.

  The connection or disconnection of the connecting portions 10 and 11 can be achieved by employing various known means, but is preferably performed by elevating and lowering the drive motor 9 in the vertical direction, for example. Specifically, when the drive motor 9 is raised, both the connecting portions 10 and 11 are released, and when the drive motor 9 is lowered, both the connecting portions 10 and 11 are connected and the driving force of the drive motor 9 is driven. It is transmitted to the tire 8. Thereby, connection operation of both the connection parts 10 and 11 can be performed comparatively easily.

  Moreover, both the connection parts 10 and 11 have the uneven | corrugated tooth | gear made from metal or a synthetic resin, respectively, and the driving force of the drive motor 9 is transmitted to the drive tire 8 by meshing and connecting them. It is preferable. Thereby, not only the connection force of the both connection parts 10 and 11 in the up-down direction but also the connection force in the rotation direction can be strengthened.

  As shown in FIGS. 10 to 13, it is preferable that the drive motor 9 can move up and down together by moving up and down a lifting plate 17 attached to the side surface of the driving motor 9 in the vertical direction by the lifting guide 16. As a result, the drive motor 9 can accurately move up and down in the vertical direction. The elevating plate 17 is preferably provided with a long plate-like lever 15 that can perform an operation for elevating the elevating plate 17. As shown in FIGS. 10 to 13, the lever 15 is provided with a lever end support shaft 19 at its end, a lever rotation fulcrum 18 at a position away from the end, and the lever 15 around the lever rotation fulcrum 18. Is preferably rotatable. In this case, the lever end support shaft 19 is moved to the positions shown in FIGS. 10, 13, and 12 in order or in reverse order by the rotation of the lever 15, but the elevator plate 17 and the drive motor 9 to which the elevator plate 17 is actually attached are moved up and down. For this purpose, it is preferable to adjust the height of the lever end support shaft 19 when the lever 15 rotates by providing a lever end support bearing plate 20 that receives the lever end support shaft 19 in the horizontal direction. Specifically, when the lever 15 is moved in the direction of the arrow in the connected state of both the connecting portions 10 and 11 in FIG. 10, the lever 15 rotates counterclockwise around the lever rotation fulcrum 18 as shown in FIG. 19 moves to the right while being supported on the horizontal receiving portion of the lever end support bearing plate 20, and finally when the lever rotation fulcrum 18 and the lever end support shaft 19 are aligned vertically as shown in FIG. Therefore, it is preferable that the lever end support shaft 19 abuts on the receiving portion of the lever end support bearing plate 20 in the vertical direction and stops, and the connection portions 10 and 11 are disconnected. Similarly, it is preferable that both the connecting portions 10 and 11 can be returned to the connected state shown in FIG. 10 from the released state shown in FIG. In these methods, the distance between the lever end support shaft 19 and the lever end support bearing plate 20 in the horizontal direction in the state shown in FIG. 10 is subtracted from the distance between the lever rotation fulcrum 18 and the lever end support shaft 19. The raising / lowering plate 17 and the drive motor 9 to which the raising / lowering plate 17 is attached can be raised / lowered by the same amount. The elevation distance can be adjusted, for example, by changing these distances.

  Although an example of the device of the present invention has been described above with reference to the drawings, as long as the driving force can be transmitted to the lower side of each side surface of the cart and the driving force can be transmitted while the driving tire is contacted and pressed, the cart can be forwarded. Any replacement, addition and / or deletion of some components of the apparatus of the present invention by the prior art falls within the scope of the present invention. For example, the means for transmitting the driving force by pressing the driving tire with a spring force and the photoelectric sensor can be changed to those having a conventionally known similar function. Further, the mechanism capable of connecting or releasing the drive motor and the drive tire is not limited to the above-described example, and can be appropriately modified as long as the object and function of the present invention are not impaired.

  The basket cart pre-packing device of the present invention has an advantage that it can easily achieve continuation of the floor surface and the conveying surface without digging a pit under the floor as in the chain conveyor type, and has a simple structure with low cost. Further, there is an advantage that the cart can be easily taken out even when the drive motor is stopped. Therefore, it is extremely useful in the industry for delivering and sorting packages.
