Next, embodiments of the present invention will be described with reference to the drawings.
The illustrated embodiment is designed to be adapted to the case where the object to be inspected is an inner frame of a pachinko machine.

  As shown in FIG. 1, the inspection object lifting apparatus A according to the present embodiment includes a carriage 100 and an electric forklift 200.

  The cart 100 has a placement unit 110. The mounting portion 110 is formed in a substantially box shape by bending a steel plate or an iron plate, and extends from the front end to the rear end or the vicinity of the end portion in the center of the upper surface wall 111 in the width direction. It has a recess 112 and a side wall 113 that hangs down from the left and right ends of the upper surface wall 111. When the object to be inspected is an inner frame of a pachinko machine, the recess 112 has a size and depth that allow the bottom of the inner frame to be fitted without causing wobbling.

  On the lower surface of the upper surface wall 111 on both the left and right sides of the mounting portion 110, a pair of wheels 121 projecting downward at the front portion (right end portion in FIG. 1) and rear portion (left end portion in FIG. 1). , 122 are attached. How the wheels 121 and 122 are attached is arbitrary. Although a fixed caster can be used for the rear wheel 122, a universal caster or a ball wheel is preferably used for the front wheel 121 in order to improve the steering performance of the carriage.

  In the illustrated example, since the gap between the front leg portion 212 of the lateral frame 210 and the fork 233 of the electric forklift 200 described later is narrow, when the front wheel 121 is a free caster, the electric forklift 200 of the carriage travels to a predetermined position. The ball wheel is used in order to avoid it.

  A support member 131 protrudes from the center of the rear wall 114 in the width direction of the mounting portion 110 at equidistant positions on both the left and right sides, and the roller 130 is rotatably supported by a shaft fixed at both ends to the support member 131. ing. The top portion of the roller 130 exists on the same plane as the portion 111E of the upper surface wall 111 forming the rear end portion (left end portion in FIG. 1) of the concave portion 112, or slightly higher than that. .

  Since the roller 130 is provided, the front bottom portion of the inspection object is placed on the roller 130, and the inspection object is moved to the front of the carriage 100 (to the right in FIG. 1) and moved. Most of the weight of the object can be borne by the roller 130, and the object to be inspected can be easily placed on the mounting portion 110, and the bottom of the object to be inspected can be fitted into the recess 112 and stabilized.

Since the carriage 100 has the front and rear wheels 121 and 122, when the inspection object is placed on the placement unit 110, there is a possibility that an external force is applied to the carriage 100 to change the direction in an unnecessary direction. In order to prevent this, in a preferred embodiment, the carriage stopper 140 is provided on the side wall on the same side as the operator's dominant leg, in the left side wall in the example of FIG. I have it. The carriage stopper 140 is not necessary for the carriage 100 when the operator places the inspection object on the placement unit 110 and steps on the dominant object when the carriage is brought close to the inspection object placed on the floor surface. It is for fixing so as not to move. The cart stopper 140 may be attached to the side walls 113 on both sides.

  There is a possibility that the fixing force is insufficient when the cart is used. In the preferred example shown in FIG. 2, the carriage stopper 140 rotatably supports the tread plate 142 by the shaft 143 between the front and rear support plates 141 fixed to the rear portion of the side wall 113 of the placement unit 110. One end of a lever 146 supported so as to be freely seesawed by a shaft 145 on a support plate 144 attached at a middle position in the front-rear direction is positioned above the inner end of the tread plate 142, and a pressing piece 147 is provided on the other end of the lever 146. ing. In the state where the tread plate 142 is not stepped on with the foot, as shown in FIG. 2A, the carriage stopper 140 is held so that neither the tread plate 142 nor the pressing piece 147 is in contact with the floor surface. It is biased by a spring (not shown).

  As shown in FIG. 2 (b), the cart stopper 140 shown in FIG. 2 has its front end strongly pressing the floor surface when it is stepped on, and the front end of the lever 146 that is rotated by the tread plate 142 is pressed. The piece 147 also strongly presses the floor surface. Thereby, the trolley | bogie 100 is stably fixed to a floor surface. In FIG. 2, a part of the side wall 113 is deleted.

  In addition, the carriage 100 includes a locking member 271 that forms a locking unit 270 together with a locking member 271 provided in a vertical frame 230 of the electric forklift 200 described later, in the approximate center of the front wall 115 of the mounting portion 110. A to-be-latched member 272 that is latched by the projection is protruded (see FIGS. 9C and 9D).

  Further, the bogie 100 is formed with a fork insertion portion 160 formed by adhering a long member having a U-shaped cross-section to the lower surface of the bottom wall of the recess 112 of the mounting portion 110 with the opening surfaces facing each other. Has been. The fork insertion portion 160 is continuous from the lower side of the front wall 115 to the rear wall 114 and opens forward of the carriage (rightward in FIG. 1 and leftward in FIG. 2). The fork 233 of the electric forklift 200 can be inserted / removed. The fork insertion portion 160 is preferably formed with a wide opening so that the fork 233 can be smoothly inserted and a tight insertion state can be maintained.

  Next, the electric forklift 200 will be described. The electric forklift 200 includes a horizontal frame 210, a column 220, a vertical frame 230 provided with a fork and an object to be inspected means, an electric elevating means 240 for elevating and lowering the vertical frame 230 by power, and elevating and lowering the electric elevating means. And a power supply unit 260 that supplies power to the electric lifting and lowering means 240 via the control unit 250.

  The horizontal frame 210 has a base portion 211 extending in the width direction at a position slightly rearward of the intermediate position in the front-rear direction, a front leg portion 212 extending horizontally and parallel forward from both ends of the base portion, and rearward It has a rear leg 213 that extends, and a wheel 214 is attached to the tip of each leg. Therefore, the electric forklift 200 can be moved by the wheels 214.

  The column 220 is erected vertically to the center in the longitudinal direction of the base 211 of the horizontal frame 210. The column 220 has a height that is substantially equal to a height that can be reached by a worker who performs an inspection work or the like of the inspection object in a standing posture. Moreover, the support | pillar 220 has the groove | channel 221 opened to a front surface from the upper end part to a lower end part. A cover 222 is attached to the top of the column 220.

  The vertical frame 230 is firmly configured by connecting a plurality of vertical members 231 separated in the horizontal direction by a plurality of horizontal members 232 spaced in the vertical direction. The vertical frame 230 is provided on the front side of the column 220 and accommodates a pair of left and right rollers (not shown) attached to the back of at least two horizontal members 232 in the groove 221 of the column 220. The vertical frames 230 are guided so as to be movable up and down along the columns 220 by bringing the opposite surfaces of the two into contact with the opposing surfaces of the grooves 221.

  Further, at the lower end portion of the vertical frame 230, two pieces extending forward in a horizontal and parallel manner at positions spaced from the center in the width direction of the vertical frame 230 to the left and right sides at a distance narrower than the distance between the front legs 212 of the horizontal frame 210. Fork 233 is provided. The length and interval of the two forks 233 are set substantially equal to the depth dimension and interval of the left and right fork insertion portions 160 of the carriage 100. That is, the fork 233 is formed so that it can be inserted into and removed from the fork insertion portion 160 of the carriage 100.

  Furthermore, an inspection object presser 234 is provided at the upper end of the vertical frame 230 so as to be positioned above the fork 233. As will be described later, the inspection object pressing means 234 holds the inspection object when the carriage 100 on which the inspection object is placed is placed between the front legs 212 of the electric forklift 200. It is attached and fixed. As shown in FIG. 5, the inspection object pressing means 234 is rotatably supported by an arm member 234a fixed to the horizontal member 232 at the upper end of the vertical frame 230 and a shaft 234b at the tip of the arm member 234a. A U-shaped support member 234c, a roller 234d as a pressing member rotatably mounted in the distal end portion of the support member 234c, and a base end portion of the support member 234c and the arm member 234a are provided. And a tension spring 234e as a biasing member.

  With the above configuration, the roller 234d is always urged downward so that its lower surface protrudes downward from the lower surface of the mounting member 234a.

  The electric lifting / lowering means 240 is a position immediately before the upper end of the vertical frame 230 comes into contact with the cover 222 at the upper end of the column 220 from the lower limit position where the lower end of the vertical frame 230 is held in contact with the horizontal frame 210. It moves up and down between the upper limit position. For example, such an electric lifting means 240 winds a rope of an electric winch (not shown) attached to the back of the support 220 around a pulley (not shown) attached to the upper end of the support 220, and the rope is attached to the support 220. It is possible to adopt a configuration in which the leading end is coupled to the upper end portion of the vertical frame 230.

  The control unit 250 that controls the electric lifting / lowering unit 240 is responsible for supplying and stopping the supply of power to the electric lifting / lowering unit 240 from a power supply unit 260 attached to the back surface of the column 220. For example, as shown in FIG. 6, the control unit 250 includes a lower limit switch 251 that is operated when the vertical frame 230 is lowered to the lower limit position, and an upper limit switch that is operated when the vertical frame 230 is raised to the upper limit position. 252. Further, the control unit 250 is provided with an up switch 253 and a down switch 254.

When the raising switch 253 is operated, the controller 250 causes the electric winch of the electric elevating means 240 to wind up and raises the vertical frame 230. When the operation of the lift switch 253 is stopped when the raised vertical frame 230 reaches a height position suitable for the operator to perform work such as inspection of the inspection object in a standing posture, the winding operation of the electric winch Is to be stopped. That is, the inspection object can be stopped at an arbitrary position where the work is easy. In addition, when the lowering switch 254 is operated, the control unit 250 causes the electric winch of the electric lifting / lowering means 240 to be lowered to lower the vertical frame 230. When the lower limit switch 251 is operated by the lowered vertical frame 230, the electric winch lowering operation is stopped.

The operation when using the inspection object lifting apparatus having the above-described configuration will be described. As shown in FIG. 7A, when the inspection object M is mounted on the carriage 100, the longitudinal direction of the groove 112 of the placement section 110 of the carriage 100 placed on the floor is placed on the same floor. It matches with the longitudinal direction of the inspection object M, and the shoulder of the inspection object M on the cart 100 side is pushed up, and as shown in FIG. A wedge-shaped gap is formed between them, and the carriage 100 is moved on the floor surface while maintaining the state. As shown in FIG. 8C, the top surface of the roller 130 at the end of the carriage 100 is moved. Is brought into contact with the bottom surface of the inspection object M. Next, while stepping on the cart stopper 140 to suppress unnecessary movement of the cart 100, as shown in FIG. 8 is pushed upward, and as shown in FIG. 8 (e), the bottom of the inspection object M is further moved forward while being fitted and guided in the groove 112 of the mounting portion 110, as shown in FIG. ), The bottom of the inspection object M is fitted into the groove 112. Thereby, the inspection object M is held in a stable state by the carriage 100.

Next, the carriage 100 on which the inspection object M is placed is caused to travel on the floor, and is advanced in a straight direction toward the forks 233 between the front legs 212 of the electric forklift 200 as shown in FIG. . When the front wheels 121 and the rear wheels 122 of the carriage 100 are all fixed wheels (wheels that do not swing), the carriage 100 is moved forward in a straight direction toward the forks 233 between the front legs 212 of the electric forklift 200. It is not easy, and the front side surface or the like of the mounting portion 110 of the carriage 100 cannot collide with the front leg portion 212 or the fork 233 to smoothly advance to a predetermined position. However, in a preferred embodiment, the front wheel 121 of the carriage 100
The so it is the universal wheel (wheel that the swing), Ri steering ease der of the carriage 100, the carriage 100 easily be straight forward in toward the fork 233 between the front leg portion 212 of the electric forklift 200 it can.

  When the distance between the front leg portion 212 and the fork 233 of the electric forklift 200 is narrow as shown in FIG. 1, when the front wheel 121 is a free caster, the free caster comes into contact with the front leg portion 212 and the fork 233 and is smooth. There is a possibility that you cannot enter. However, when a ball car is used for the front wheel 121, such a difficulty is also eliminated.

The operation of the inspection object pressing means 234 when the carriage 100 moves to a predetermined position between the front legs 212 of the electric forklift 200 will be described with reference to FIGS. 9A to 9D. When the carriage 100 moves forward between the front leg portions 212 of the electric forklift 200 and reaches a predetermined position, the front corner portion where the front wall and the upper surface wall of the object M to be advanced continue is slightly more than the center of the press roller 234d. It contacts the lower peripheral surface. Therefore, the pressing roller 234d is pushed up against the urging force of the urging member 234e while being rotated, and as the carriage 100 is further advanced, as shown in FIG. Step on and apply pressing force to the inspection object M. Then, when the carriage 100 is further advanced and the front end portion of the carriage 100 is advanced to a predetermined position, as shown in FIG. 9C, the carriage 100 hits the vertical frame 230 of the electric forklift 200 and is stopped. At this time, since the pressing roller 234d presses the inspection object M at a position close to the rear corner portion of the upper surface wall of the inspection object M by the urging member 234e, the inspection object M is pressed against the pressing roller 234d. It is fixed in a stable state with the carriage 100.

  Subsequently, the lift switch 253 of the control unit 250 of the electric forklift 200 is operated to operate the electric lifting / lowering means 240 and the carriage 100 is raised. During this rise, the carriage 100 is moved from the electric forklift 200 more. Specifically, it is desirable to provide means for preventing unnecessary movement in a direction away from the vertical frame 230. Therefore, in a preferred embodiment of the present invention, it is possible to prevent the carriage 100 from being unnecessarily moved from the rising electric forklift 200 and to automatically lock and unlock the carriage 100 to the electric forklift 200. Locking means 270 is provided.

  As shown in FIGS. 9C and 9D, the locking means 270 is a locking member 271 protruding in the direction opposite to the cart forward direction at the center in the width direction of the vertical frame at the lower end of the vertical frame 230 of the electric forklift 200, for example, It consists of a hook and a locked member 272 provided at the front end of the mounting portion 111 of the carriage 100, for example, a square C channel.

  As shown in FIG. 9C, the hook 271 is attached so as to be at the same height as the opening of the square C channel 272 of the carriage 100 when the vertical frame 230 exists at the lower limit position. Accordingly, the electric forklift 200 of the carriage 100 can freely move forward and backward to a predetermined position, but when the vertical frame 230 starts to be raised by the electric lifting means 240, the hook 271 is connected to the square C channel as shown in FIG. 9D. The cart 100 is securely held without being separated from the electric forklift 200 because it is engaged with the H.272. Therefore, thereafter, the inspection object M can be safely raised to a predetermined height position. Note that Japanese Patent No. 4580098 discloses a method of fixing the inspection object only at the bottom part, but it is difficult to maintain safety when the inspection object is vertically long and heavy.

  When the operator stops the operation of the raising switch 253 when the cart 100 is raised to the predetermined height position by the electric lifting / lowering means 240, the control unit 250 stops the raising by the electric lifting / lowering means 240. Thereby, as shown in FIG. 10, the inspection object M is held at a height position where the worker can easily work in the standing posture. Therefore, the operator can easily assemble, replace, or inspect parts for the inspection object M, and prevent back pain and the like.

  When the inspected object M has electric parts, the electric forklift 200 needs to be equipped with a power source for inspection in addition to the power source for the electric lifting means. Although it is possible to provide separate power supplies, there is a problem in securing installation space and reducing power supply costs. Therefore, in a preferred embodiment of the present invention, a single power supply unit 260 is provided with, for example, a power supply for electric lifting means 261 of 100 V and a power supply 262 for inspection of 24 V, for example. As a result, the advantages of both securing the installation space and reducing the power supply cost are obtained.

Another embodiment of the present invention will be described.
Although not shown, the electric elevating means 240 includes a nut provided on the vertical frame 230, a ball screw attached to the support 220 and screwed to the nut, a motor provided on the support 220 and rotating the ball screw, It can also be comprised with the control part 250 which controls the power supply to a motor.

  The carriage 100 can be provided with a turntable with a rotation stopper (not shown) on the upper surface of the mounting portion 111 so as to be rotatable. As an example, the turntable can be stopped at that angle by a rotation stopper every time it is rotated 180 degrees. Therefore, when this cart is used, parts can be exchanged and inspected on the front side and the back side of the inspection object at one work position.

  A support member 131 that supports the roller 130 of the carriage 100 is formed in a cylindrical shape, and the lower end portion of the handle 300 provided with a stopper 302 near the lower end portion of the inverted U-shaped gripping member 301 as shown in FIG. When it is possible to insert and fix the support member 131 on the carriage 100, after placing the inspection object M on the carriage 100, the handle 300 is inserted and fixed to the support member 131, and the handle 300 is held and pushed. The cart 100 on which the inspection object M is placed can be moved on the floor more easily like the wheelbarrow. The handle 300 is suitable when the object to be inspected M is difficult to push directly by hand.

  The inverted U-shaped gripping member 301 of the handle 300 is preferably made by bending a pipe to reduce the weight. The stopper 302 performs a positioning operation when the handle 300 is inserted into the gripping member 131. Therefore, although it may be short, if it is continuous between the vertical portions on both sides of the U-shaped member 301 as in the illustrated example, it has a function of securing strength. However, when the support member 131 is formed in a bottomed cylindrical shape that opens upward, the stopper 302 near the lower end of the handle 300 is not necessary. However, in order to facilitate attachment / detachment of the U-shaped gripping member 301 made of a pipe to the carriage 100 and to reinforce the gripping member 301, the height direction of the vertical portions on both sides of the gripping member 301 It is desirable to connect a horizontal and thin reinforcing member to the intermediate position.

  The height dimension of the inspection object is not always constant. Therefore, in order to make the inspection object lifting / lowering device A applicable to inspection objects of different heights, it is desirable that the attachment position of the inspection object pressing means 234 with respect to the vertical frame 230 is made variable by known attachment means.

  Further, the shape of the member forming the fork insertion portion of the carriage 100 and the number and shape of the forks 233 of the electric forklift 200 are not limited to the illustrated example, and are arbitrary.

  Furthermore, the inspection object lifting device does not include the cart 100 as an indispensable element. The electric forklift 200 may be used alone, and the object to be inspected may be directly slid onto the fork 233. Alternatively, as a substitute for the carriage 100, a pallet having no wheels may be used.
