Description

Technical Field

[0001] The present invention relates to a trolley for transporting panels, and particularly to a mobile object horizontal / vertical conversion device without power that can hold the transported panel in a vertically standing state and a horizontally lying state.

Background Art

[0002] Conventionally, trolleys have been used for transporting panels in factories and the like. The panel to be processed is moved to the work location by the trolley, placed on the workbench by the operator, and various processes are performed. When the panel to be processed is relatively light, it can be placed on the workbench without particular difficulty. However, when it is a heavy object exceeding 50 kg, it becomes difficult for one operator to place it on the workbench from the transport trolley. Particularly during transportation, in order to move smoothly along the passage in the factory, the panel is often transported in a standing state, while it needs to be placed horizontally when placed on the workbench.

[0003] Therefore, in Patent Document 1 (Japanese Unexamined Patent Application Publication No. 2019-171990), as a panel transport trolley that can hold the panel in a vertically standing state and a horizontally lying state, it includes a wheeled base frame placed on the floor surface, and a swing frame that is swingably supported around a horizontally arranged swing axis on the base frame and holds the panel to be transported vertically or horizontally with respect to the floor surface. The swing axis is arranged at a position lower than the center of gravity of the panel in a state where the panel is held vertically with respect to the floor surface. A panel transport trolley is proposed.

Summary of the Invention

Problems to be Solved by the Invention

[0005] Patent Document 1 proposes a panel transport trolley that can hold panels in both a vertically upright position (hereinafter also referred to as the "upright position") and a horizontally lying position (hereinafter also referred to as the "lying down position"). According to the panel transport trolley proposed in this document, when a panel that has been transported in an upright position is laid horizontally, the height of the panel from the floor surface can be reduced. However, when moving a panel from a horizontally lying position to a vertically upright position, there is a concern that the panel may fall to the opposite side depending on the momentum. Therefore, one of the objectives of the present invention is to provide a mobile object horizontal-lying and upright positioning non-electric conversion device that can safely perform the operation of raising a panel from a lying down position.

[0006] Furthermore, the panel transport trolley proposed in Patent Document 1 allows a worker standing on the floor to comfortably reach onto the top of the panel while the panel is laid horizontally parallel to the floor surface, and does not consider moving the panel to a workbench while it is laid horizontally. Therefore, another objective of the present invention is to provide a mobile, non-electrically operated device for laying panels horizontally and upright, which can transport panels that have been moved in a vertical position, lay them horizontally, and then move them to a workbench in that position.

[0007] Furthermore, the panel transport trolley proposed in Patent Document 1 can hold panels in both a vertical and horizontal position, but it cannot maintain the position during the operation. Therefore, another objective of the present invention is to provide a mobile object horizontal / upright non-electric switching device that can hold panels in both a vertical and horizontal position, and that can arbitrarily fix the position in both positions, as well as the position when changing positions, or allow arbitrary movement. [Means for solving the problem]

[0008] In order to solve at least one of the above problems, the present invention does not require a power supply, etc. andThe present invention provides a mobile object horizontal / upright positioning non-electric conversion device that can hold and move objects such as panels in an upright position (leaning against a wall) and a horizontal position (lying on its side) without the need for motors. This mobile object horizontal / upright positioning non-electric conversion device comprises a base frame equipped with wheels, a pivot shaft held horizontally on the base frame, and a pivot part capable of supporting the panel to be transported and pivoting around the axis of the pivot shaft, wherein the pivot part has a starting point and an ending point for the pivoting motion, and the direction of the pivot is such that the two sides are opposite to each other. Applying a force in the opposite direction It can be formed by providing a motion buffer.

[0009] Such an action buffer can consist of a lower action buffer that biases the oscillating part in the opposite direction to the direction of oscillation at the end of the movement to lay the oscillating part down, and an upper action buffer that biases the oscillating part in the opposite direction to the direction of oscillation at the end of the movement to raise the oscillating part upright. In particular, the lower action buffer can be provided below the oscillation axis when the oscillating part is in the upright position, and the upper action buffer can be configured to bias the oscillating part in the opposite direction to the direction of oscillation at the end of the movement to raise the oscillating part upright. Such an action buffer can preferably be made of a constant-load spring, but it can also be formed using springs, rubber, other elastic members, or dampers.

[0010] Furthermore, in the mobile object tilting / standing non-electric switching device of the present invention, it is desirable to provide an operation restricting unit that restricts the swinging motion of the swinging unit, and to enable the swinging motion by releasing the operation restricting unit. That is, the operation restricting unit can be formed to stop or release the swinging motion of the swinging unit, and for example, a gas damper with a locking function can be used, and by installing the gas damper in connection with the swinging unit and the base frame, the swinging unit can be held at any position by turning the operation restricting unit on / off. The operation restricting unit can also be configured to stop the swinging motion by releasing the operation restricting unit. That is, the swinging motion is always possible, and the operation restricting unit is released. to Therefore, it can also be configured to prohibit the rocking motion.

[0011] Furthermore, in the mobile object horizontal / upright non-electric switching device of the present invention, the oscillating part is provided with a flat surface that contacts the panel to be transported, and it is desirable that rollers for horizontally moving the panel in a lying position (i.e., inverted position) are provided on this flat surface.

[0012] Furthermore, it is desirable that the oscillating part be provided with a panel support portion that protrudes to the front side at the lower end when the part is upright (i.e., in the upright position) and on which the panel to be transported is placed, and that rollers be provided on the panel support portion.

[0013] Furthermore, the present invention provides a mobile, non-electrically operated device for tilting or leaning objects, comprising a base frame equipped with wheels, a pivot shaft held horizontally on the base frame, a pivot part capable of supporting a panel to be transported and pivoting around the axis of the pivot shaft, and an operating buffer part that applies a force in the opposite direction to the pivoting direction at the starting and ending points of the pivoting motion of the pivot part.

[0014] In such a non-electrically operated device for horizontally or vertically placing a movable object, it is desirable to use a constant-load spring as the operating cushioning member, and it is desirable that the constant-load spring be provided on the lower and upper sides of the pivot axis when the pivoting part is in an upright position. [Effects of the Invention]

[0015] The present invention provides a non-electrically operated device for moving objects to be placed horizontally or upright, in which the starting and ending points of the oscillating motion in the oscillating part are relative to each other in terms of the direction of oscillating. Applying a force in the opposite directionBecause it is equipped with a motion buffer, the momentum at the end of each operation can be reduced in both the uprighting operation, which raises a panel from a lying position to an upright position, and the downing operation, which lays a panel down from an upright position. As a result, even when raising a panel that is lying horizontally to a vertical position, the momentum at the end of the operation can be reduced, preventing the upright panel from falling over to the opposite side due to excessive force. Furthermore, it can be made into a mobile object horizontal / upright non-electric conversion device that can safely perform the operation of raising a panel that is lying down. Applying a force in the opposite direction The motion buffering section applies force in the tilting direction when the oscillating section is in an upright position, thereby assisting the tilting motion and realizing a mobile object tilting / tilting / uprighting non-electric conversion device that can easily perform the tilting motion.

[0016] Furthermore, even when laying down a panel that is in an upright position, the aforementioned motion buffer acts in the opposite direction to the direction of the fall at the end of the fall-down motion, preventing it from falling over forcefully. As a result, even if the pivot axis is located below the center of gravity of the panel being transported, the panel will not fall over forcefully, ensuring safety during work and enabling a smooth fall-down motion. Applying a force in the opposite direction The motion buffer applies an upright force to the oscillating part in a fallen state, thereby assisting in the operation of raising the fallen panel, and realizing a mobile object horizontal / upright non-motorized conversion device that can easily perform the uprighting operation.

[0017] Furthermore, by providing an action restricting unit that restricts the swinging motion of the swinging part, and by releasing the action restricting unit to enable the swinging motion, unintended tilting or standing motions can be eliminated, thereby ensuring safety during work. Moreover, by providing the action restricting unit, the swinging part can be held at any angle and posture, so the tilt angle of the swinging part, and by extension the panel, can be adjusted according to the work environment.

[0018] Furthermore, when rollers for horizontally moving the panel in a laid-down state are provided on the swinging part, the transfer of the panel in the laid-down state from the movable object horizontal-lying / standing-up-and-leaning non-electric conversion device to the workbench can be easily performed. Also, when a panel receiving part protruding to the front side is provided on the lower end side of the swinging part in the standing state, the loading and unloading operations of the panel in the standing state can be smoothly carried out. Thereby, a movable object horizontal-lying / standing-up-and-leaning non-electric conversion device that can horizontally lay down the panel transferred in a vertically standing state and move it to the workbench in that state is realized.

Embodiments for Carrying out the Invention

[0020] Hereinafter, the movable object horizontal-lying / standing-up-and-leaning non-electric conversion device 50 according to the present embodiment will be specifically described with reference to the drawings. In particular, the present embodiment is a movable object horizontal-lying / standing-up-and-leaning non-electric conversion device 50 that can transfer a plate-like panel P in a standing state and then move it onto a workbench T in a horizontally laid-down state.

[0021] Figure 1 shows (A) a front view and (B) a side view of the mobile object lying-down / upright non-motorized conversion device 50 according to this embodiment, Figure 2 shows (A) an upright state and (B) a collapsed state of the mobile object lying-down / upright non-motorized conversion device 50, and Figure 3 shows (A) a front view and (B) a top view of the transfer state of the panel P by the mobile object lying-down / upright non-motorized conversion device 50.

[0022] As shown in Figure 1, the mobile object horizontal / upright non-motorized switching device 50 according to this embodiment includes a base frame 20 equipped with wheels 21, a pivot shaft 30 held horizontally on the base frame 20, a pivot part 10 capable of supporting the panel P to be transported and pivoting around the axis of the pivot shaft 30, and the pivoting motion of the pivot part 10. Applying a force in the opposite direction It is formed by the operating cushioning part 28.

[0023] In this embodiment, the base frame 20 is formed as a frame assembled from pipes or the like, but it can also be formed using plate materials. This base frame 20 constitutes the base of the mobile object tilting / leaning non-electric conversion device 50, and various components can be attached to this base frame 20 directly or indirectly via other members. In this embodiment, the lower surface of the base frame 20 is provided with wheels 21 for moving the mobile object tilting / leaning non-electric conversion device 50, and also with stoppers 22 to prevent the movement of the mobile object tilting / leaning non-electric conversion device 50. These stoppers 22 are provided so as to be able to move back and forth relative to the moving surface of the mobile object tilting / leaning non-electric conversion device 50, and by pressing against the moving surface, the movement of the mobile object tilting / leaning non-electric conversion device 50 can be prevented.

[0024] And the base frame 2 0Support columns 23 are erected on both sides of the upper surface in the width direction. These support columns 23 can hold the pivot shaft 30 and also function to hold the pivoting part 10. Therefore, the pivot shaft 30 is supported by these two support columns 23 and is supported horizontally on the base frame 20.

[0025] This support column 23 is configured as a double lever mechanism in a four-bar linkage mechanism to move the swinging part 10 between an upright and a collapsed state. Specifically, it constitutes a four-bar linkage mechanism (particularly a double lever mechanism) consisting of a leg link 24 that acts as a lever and is positioned parallel to and opposite the support column 23 which is a fixed link, an upper link 25 that connects the upper part of the support column 23 to the upper part of the leg link 24, and a lower link 26 that connects the lower part of the support column 23 to the lower part of the leg link 24. The upper link 25, the leg link 24, and the lower link 26 are each connected by a rotatonic connection.

[0026] Furthermore, at the joint portion (paired portion) between the support column 23 and the upper link 25, and at the joint portion (paired portion) between the leg link 24 and the upper link 25, there are pivot support columns 27 that protrude in a direction perpendicular to the upper link 25, and the pivot support columns 27 hold the pivot 10. In other words, the pivot 10 is fixed to a total of four pivot support columns 27 that protrude from the ends of the upper links 25 located on both sides in the width direction of the base frame 20, and can perform the same operation as the upper link 25.

[0027] Furthermore, a lower operating buffer 28a is provided on the lower end side of the swinging part 10, specifically below the swinging part support column 27 that protrudes from the joint portion (paired pair) between the support column 23 and the upper link 25, which biases the swinging part 10 with a force in the opposite direction when it swings in the tilting direction. An upper operating buffer 28b is provided on the upper side of the swinging part 10, specifically above the swinging part support column 27 that protrudes from the joint portion (paired pair) between the support column 23 and the upper link 25, which biases the swinging part 10 with a force in the opposite direction when it swings in the upright direction. In particular, in this embodiment, the buffers 28a and 28b are constructed using constant-load springs, the lower operating buffer 28a is provided connected to the base frame 20 and the lower end of the swinging part 10, and the upper operating buffer 28b is provided connected to the base frame 20 and the joint portion (paired pair) between the leg link 24 and the upper link 25.

[0028] With the above configuration, when the oscillating part 10 is oscillated in the direction of tilting, the upper motion buffer 28b can support the movement of the oscillating part 10 in the tilting direction at the initial stage of the oscillating motion. At the end of the tilting motion (i.e., the tilting motion), the lower motion buffer 28a can apply a force in the opposite direction to the oscillating direction (the direction of tilting), thereby eliminating the risk of the oscillating part 10 falling over forcefully. On the other hand, when the oscillating part 10 is oscillated in the upright direction (the standing direction), the lower motion buffer 28a can support the movement of the oscillating part 10 in the upright direction at the initial stage of the oscillating motion. At the end of the upright motion (i.e., the standing motion), the upper motion buffer 28b can apply a force in the opposite direction to the oscillating direction (the standing direction), thereby eliminating the risk of the panel P held by the oscillating part 10 falling over forcefully in the oscillating direction.

[0029] Furthermore, in this embodiment, an operation restricting unit 29 is provided to restrict the swinging motion of the swinging unit 10. In this embodiment, the operation restricting unit 29 uses a gas damper, which is installed in a series between the base frame 20 and the upper link 25. The lock of this gas damper can be released by a lever 13 provided on the side of the swinging unit 10, and by releasing the lock with the lever 13, the swinging motion of the swinging unit 10 can be performed. Therefore, by operating the lock during the upright or downward movement of the swinging unit 10, the swinging unit 10 can maintain that state. By providing such an operation restricting unit 29, it is possible to maintain the posture during the swinging motion, and unintended downward or upright movements can be prevented, thereby improving work safety.

[0030] In the mobile object tilting / standing non-motorized conversion device 50 according to this embodiment, it is desirable that the center of gravity of the panel P to be transported is located in front of the swing axis 30. By having the center of gravity of the panel P to be transported on or in front of the swing axis 30 (forward direction), i.e., in the upright movement direction, it becomes possible to transport it stably while maintaining a slightly upright position. However, in the mobile object tilting / standing non-motorized conversion device 50 according to this embodiment, since the operation restricting unit 29 consisting of a gas damper with a locking function is provided, even if the center of gravity of the panel P to be transported is located behind the swing axis 30 (in the tilting movement direction), it is possible to transport it while maintaining a slightly upright position without swinging in the tilting direction.

[0031] In the mobile object horizontal / upright non-electric switching device 50 of this embodiment, the oscillating part 10 can be configured to have a flat surface that contacts the panel P to be transported. Such an oscillating part 10 can be formed, for example, using a plate. It is desirable to provide rollers 14 on this flat surface for horizontally moving the panel P in a horizontal position. This is so that the panel P, which has been transported in an upright position, can be placed in a horizontal position at the destination and used to transfer it to the workbench T. By providing such rollers 14, even heavy panels P can be transferred to the workbench T without particular difficulty.

[0032] Furthermore, in the mobile object tilting / standing non-motorized conversion device 50 according to this embodiment, it is desirable to provide a panel support portion 11 on the swinging portion 10 for supporting the panel P in an upright, slanted position. The panel support portion 11 is located on the lower end side of the swinging portion 10, that is, on the lower end side when it is upright, protruding towards the front, and can be configured to hold the panel P to be transported. By providing rollers 12 on this panel support portion 11, the panel P to be transported can be smoothly placed on the mobile object tilting / standing non-motorized conversion device 50 in an upright position.

[0033] Figure 2 shows a non-electrically operated mobile object horizontal / upright placement device 50 according to this embodiment, (A) a side view showing the upright state when a panel is being transported, and (B) a side view showing the tilted state when the transported panel is being placed on the workbench T. As shown in Figure 2(A), when the panel to be transported is in an upright state, its load acts on the swinging part 10, which is supported by the support column 23. The swinging part 10 in the upright state is held in place by the brake mechanism (operation restricting part 29) of the gas damper, so that the panel P placed on the panel receiving part 11 can be transported in an upright state. As a result, it can pass through even narrow passages in factories and facilities without difficulty.

[0034] When the panel reaches the workbench T, which is the destination of the transport, the swinging part 10 is lowered, as shown in Figure 2(B), and the panel P is laid down. This lowering operation can be performed by releasing the swinging restriction in the movement restricting part 29 and operating the four-bar link mechanism (especially the double lever mechanism), as described above. Specifically, this can be done by lowering the leg link 24 to the moving surface (floor or ground). In this state, with the swinging part 10 lowered, the panel P placed on the swinging part 10 can assume a horizontal position, and its load can be supported by the support column 23 and the leg link 24. The panel P, held in this horizontal position, can be moved onto the workbench T without requiring much force by the rollers 14 provided on the flat surface of the swinging part 10, which is made of a plate.

[0035] After the processing is completed on the workbench T, the oscillating unit 10, which is held horizontally, can be slid back into place and transported in an upright position as shown in Figure 2(A).

[0036] Figure 3(A) is a front view showing the state in which the panel P to be transported is transferred to a transport trolley, and Figure 3(B) is a top view showing the state in which the transported panel P is moved to the work table T. As shown in Figure 3, the panel P, which has been transported in an upright position on a trolley or the like, can be moved to the mobile object tilting / leaning non-motorized conversion device 50 according to this embodiment while maintaining its upright position. Specifically, by placing it on the panel receiving part 11 provided at the lower end of the swinging part 10 and sliding it on the rollers 12 provided on the panel receiving part 11, it can be smoothly moved to the mobile object tilting / leaning non-motorized conversion device 50. At this time, by tilting the panel P so that it can lean against the swinging part 10, it can be smoothly moved by the rollers provided on the swinging part 10.

[0037] After moving the panel P to a transport location such as a workbench T, as shown in Figure 3(B), the swinging part 10 is tilted horizontally, and the horizontally positioned panel P is slid onto the workbench T. This realizes a mobile, non-electrically operated device 50 for horizontal and vertical placement of an object, which can not only change the position of the panel P between upright and tilted, but also move it to the workbench T. [Industrial applicability]

[0038] The mobile object tilting / leaning positioning non-electric conversion device according to the present invention can be used to transport panels, to transport heavy panels, and to change their upright and tilted positions as desired. Furthermore, this mobile object tilting / leaning positioning non-electric conversion device can be used not only for panels but also as a trolley to transport other plate-like objects and change their upright and tilted positions as desired.
