Description

  The present invention relates to a frame component storage device used for storing and transporting frame components when manufacturing a ball game machine represented by a pachinko machine.

  In a ball game machine represented by a pachinko machine, an outer frame formed in a vertically long outer frame shape is exclusively used as an outer frame holding frame, and is formed into a rectangular shape that matches the front opening area of the outer frame. A front frame that is hinged to be openable and closable is used as a mounting frame for mounting a ball game component, and both frames (outer frame and front frame) constitute a machine frame body that holds the entire machine body. ing. Various bullet ball game constituent members are mounted on the front frame that functions as a mounting frame to constitute a bullet ball game machine.

  When manufacturing such a ball game machine, each component (for example, outer frame, front frame, ball game component, etc.) is manufactured by the component manufacturing department and transported to an assembly factory for the ball. Assembling game machines is often performed. In such a case, the parts manufactured in each part manufacturing department are loaded on a truck and transported to an assembly factory, once transported to a parts warehouse and stored, and then unloaded from the parts warehouse according to a production plan. It is common to assemble a gaming machine. For example, a frame part with a front panel attached to the outer frame, a glass door on the front side of the front frame, and a mechanism panel called a back set panel on the rear side is made at a parts manufacturing factory. The frame parts are loaded on a truck or the like and conveyed from the parts manufacturing factory to the assembly factory.

  In transporting such frame parts, each frame part is packed and loaded on a truck, or after being stacked and fastened on a pallet in a packed state, it is loaded on a truck bed in units of pallets using a forklift or the like. In the assembly factory, these packed parts and pallets are unloaded from the loading platform and transported to the parts warehouse for storage. In such a transport mode, a lot of man-hours are required for transporting and storing the frame parts, and each frame part stacked on the pallet is taken out one by one when it is unloaded from the parts warehouse and put into the assembly line. There is a problem that a process of unpacking is required, and a large amount of waste material (packing material) is generated and a great deal of labor is required. Therefore, in order to solve such a problem, the applicant stores and holds a plurality of frame parts manufactured in the parts manufacturing department in an aligned state as they are, and efficiently transports and stores the frame parts to an assembly factory or the like. A frame component storage device for a ball game machine that can be performed has been proposed (see, for example, Patent Document 1).

JP 2002-248221 A

  According to the frame component storage device as described in Patent Document 1, the frame component storage device that stores and holds the frame components can be mounted and transported as it is on a truck or the like. Further, the frame component storage device can be easily stored in a warehouse or the like as it is. Therefore, there is no need to pack each frame component, and the work man-hours for conveying and storing the frame components can be greatly reduced.

  However, in the conventional frame component housing device, the lower guide rail member that supports the lower portion of the frame component in the lying position is bent upward at right angles with the flat bottom rail portion extending in the front-rear direction and the left and right end portions of the bottom rail portion. The frame parts in a horizontal position are supported by the lower rail part, and the back surface of the outer frame is one of the lower side guide parts. The front end of the hinge member that protrudes forward from the front frame contacts the other of the lower side guide parts, and is sandwiched and positioned by the pair of left and right lower side guide parts. For this reason, there is a possibility that the front end portion of the hinge member is in sliding contact with the lower surface guide portion during attachment / detachment work of the frame parts or conveyance by the track, and scratches the front end surface of the hinge member.

  In addition, at least in the height range supported by the lower guide member in the sideways posture, the structure cannot be protruded forward from the front end surface of the hinge member. Even if it is intended to provide a cover member for the purpose, an effective structure that covers the entire hinge connection part cannot be adopted, and even if a three-dimensional design design is applied to the glass door or ball tray, the front side of the front frame There is a problem that the degree of freedom of design and design is restricted, for example, it is difficult to adopt a design with a depth due to the limited protrusion height.

  The present invention has been made in view of such problems, and after reducing the number of work steps for transporting and storing the frame parts, the damage to the frame parts is suppressed and the degree of freedom in designing and designing the machine component parts is increased. An object of the present invention is to provide a frame component storage device for a ball game machine that can be improved.

  In order to achieve such an object, the present invention is formed in an outer frame of a vertical rectangular frame shape and a rectangular shape matched to the front side opening area of the outer frame, and via a hinge fitting on either one of the left and right sides. A frame part for storing and transporting a frame part for a ball game machine that includes a front frame that is openably and closably connected to an outer frame and a glass door provided on the front side of the front frame. The present invention relates to a storage device (for example, the frame storage unit 30 in the embodiment). In addition, the frame component storage device includes a lower guide rail member and an upper rear portion of the frame component that support the frame component in a sideways posture in which the side surface to which the hinge bracket is attached is the lower surface and the front frame surface is vertical, from the lower surface side. Is provided with an upper guide rail member that supports the right and left sides. Then, the lower guide rail member is placed in a state where the lower surface of the frame part in the lying position is extended in the front-rear direction. Left and right lower guide side guide portions that are bent upward and forward and backward, and a position defining portion that is circularly provided in a side sectional view and that protrudes upward from the front portion of the lower rail portion (for example, a position defining member in the embodiment) 35), and when the frame part is inserted into the lower guide rail member from the front in a sideways posture, either one of the left and right lower guide side guide parts is connected to the rear surface of the outer frame at the lower part of the frame part. A hole part that is slidably contacted to guide the insertion position of the frame part and the insertion angle in the front-rear direction, the upper rear part of the frame part is received and held by the upper guide rail member, and the position defining part is formed on the downward side surface of the outer frame (For example, real Is received in position defining hole 3t) in the form configured frame component is positioned.

  The position defining portion is formed in a columnar shape whose axis extends to the left and right, and the hole portion is a rectangular hole that penetrates the plate surface of the hinge fitting provided on the downward side surface of the outer frame in a sideways posture and is long to the left and right. Preferably, the position defining member is provided so as to engage with the inner peripheral surface of the hole formed in the hinge fitting.

In this case, the position defining member is fixed by being fitted into a rectangular fixing hole formed in the lower rail portion in accordance with the length of the position defining member, and the axis extending in the left-right direction is associated with the inner peripheral edge surface of the hinge bracket opening. It is preferable to arrange at a height position (for example, the height h _{1 in the} embodiment).

  Further, in the present invention, the inner width interval between the left and right lower guide side guide portions is set to be larger than the left and right outer width dimension of the lower part of the frame part in the sideways posture, and the lower side facing the front surface of the frame part. It is preferable that a buffer member for protecting the frame parts is attached to the side guide portion for guide.

  Further, the upper guide rail member has left and right upper guide side guide portions facing the front and rear surfaces of the outer frame at the upper rear portion of the frame component in the lying position, and a rear upper stopper portion facing the rear surface of the outer frame, respectively. The bottom rail portion is a circle positioned in front of the position defining member and projecting upward from the position defining member so that the axis extends to the left and right in parallel with the position defining member, and the axial length is longer than the position defining portion. A frame part having a columnar lower stopper portion (for example, the lower stopper 36 in the embodiment) and in a lying position slides forward on the upper surface of the lower rail portion in a state where the position defining portion is received in the hole portion. When the position defining portion and the hole portion are engaged, it is preferable that the peripheral surface of the lower stopper portion is in contact with the front end surface of the outer frame to prevent the frame component from dropping out forward.

  On the other hand, the container cart according to the present invention has a container main body configured with a plurality of frame parts storage devices for ball game machines configured as described above, and the container main body moves on the lower surface of the container main body. It has a plurality of caster wheels that are freely supported.

  When the frame component storage device for a ball game machine of the present invention is used, one of the left and right lower guide side guide portions in the bottom rail portion is in sliding contact with the back surface of the outer frame, and the insertion position and the insertion angle of the frame component The position defining portion provided so as to project upward from the front portion of the lower rail portion is received in a hole portion formed in the downward side surface of the outer frame to position the frame component. That is, the frame part accommodated in the storage device is not positioned and held by the front and rear surfaces of the frame part being sandwiched between the left and right guide side guide parts, but a position defining part provided protruding from the lower rail part. It is configured to be received and positioned in a hole formed in the downward side surface of the outer frame. For this reason, the front end of the hinge member and the front surface of the glass door do not come into contact with the lower side guide part during the transportation of the frame part and are not damaged. The degree of freedom in design can be improved. In addition, since the position defining portion that protrudes upward is formed in a circular shape when viewed from the side (for example, a spherical shape, a cylindrical shape that is long to the left or right, or a semicircular bowl shape, etc.), Even if the side faces the position defining portion and moves, it will not be damaged. Therefore, it is possible to provide a positioning and holding structure that is unlikely to damage the downward side surface of the outer frame while providing a position defining portion that protrudes upward on the lower rail portion.

  In the present invention, the position defining portion is formed in a cylindrical shape extending in the left-right direction in the axial direction, and the hole on the outer frame side passes through the hinge fitting fixed to the downward side surface and opens into a square hole shape that is long on the left and right According to the configuration in which the position defining member is engaged with the inner peripheral surface of the hole, the hole formed in the metal hinge fitting and the columnar position defining portion are engaged. It is possible to prevent the hole from being damaged and to achieve a strong and reliable positioning and holding. Even when the frame frame is inserted and removed, the downward side surface of the outer frame rides on the position defining portion and moves, so that the downward side surface of the outer frame is damaged because it slides back and forth so as to slide on the outer peripheral surface of the cylinder. There is no such thing as giving. In addition, depending on the engagement form between the square hole and the cylinder, it is possible to provide optimum required position accuracy (reversely, appropriate clearance considering handling) in the front-rear direction and the left-right direction.

  In this case, according to the configuration in which the position defining member is fitted and fixed in the rectangular fixing hole, and the axis extending in the left-right direction is disposed at a height position that engages with the inner peripheral surface of the opening of the hinge fitting, the position defining member is provided. When the frame part moves relative to the member in the left-right direction (the axial direction of the position-defining member) and the shaft end of the position-defining member engages with the opening inner peripheral surface of the hinge bracket, the diameter of the pressure receiving area is wide. It is possible to engage the portion and receive the pressing force, and transmit the received axial pressing force as it is to the fixing hole on the other end side to be dispersed. That is, according to such a configuration, the internal stress generated in both members is reduced at the engaging portion between the shaft end of the position defining member and the inner peripheral surface of the hinge metal fitting, thereby preventing damage or deformation of both members. In addition, by inserting and fixing the position defining member in the fixing hole, the shearing force acting on the welded portion can be significantly reduced, and peeling damage to the position defining member can be prevented. In addition, even when the frame part relatively moves in the front-rear direction and the peripheral surface of the position defining member engages with the inner peripheral surface of the opening of the hinge bracket, the vertical portion of the circular sectional position defining member is the inner periphery of the opening of the hinge bracket. Since it is engaged with the surface, the positioning structure has a high holding force.

  Further, in the present invention, the inner width interval of the left and right lower guide side guide parts is set larger than the outer width dimension of the lower part of the frame part, and the lower guide side guide part on the side facing the front surface of the frame part, According to the configuration in which the shock-absorbing member for protecting the frame member is mounted, the worker mistakenly tilts the frame component in the front-rear direction when attaching or detaching the frame component, and the front end of the hinge member or the front surface of the glass door Even in the case of contact with the guide portion, these contact portions are not damaged, and damage to the frame parts can be reliably prevented.

  The upper guide rail member has left and right upper guide side guide portions and an upper stopper portion, and the lower rail portion projects in front of the position defining member above the position defining member and extends in parallel with the position defining member. It has a cylindrical lower stopper part whose axial length is longer than the position defining part, and with the position defining member received in the hole part, the frame component in the lying position slides forward on the upper surface of the lower rail part. Then, when the position defining portion and the hole portion are engaged, the outer peripheral surface of the lower stopper portion is in contact with the front end surface of the outer frame, and the frame part is prevented from falling forward. For example, when the frame part slides forward due to vibration or the like during conveyance of the frame part, in addition to the engagement between the position defining part and the hole part, the lower stopper is longer than these engagement lengths and has a high engagement position. The movement of the frame parts is prevented by the engagement between the portion and the front end surface of the outer frame. Therefore, it is possible to provide a frame component storage device in which the holding stability is further improved without the frame component slipping out of the storage device and falling off.

  On the other hand, if a container cart provided with a container main body configured with a plurality of frame part storage devices as described above and a plurality of caster wheels that movably supports the container main body is used, a plurality of frame parts are containerized. The container cart can be stored and held as it is, and the container cart can be moved freely and easily. In addition, it is easy to load and transport container carts that store frame parts in trucks as they are, and to carry them in warehouses as they are, providing excellent transportation and storage efficiency, as well as packing material costs and packaging / unpacking. The incidental man-hours can be reduced.

  Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. Before describing the frame component storage device and container cart for a ball game machine according to the present invention, first, a pachinko machine configured using frame components stored and held by the storage device will be described.

  The outer frame 1 is formed in a rectangular frame shape from an upper frame plate 1a made of wood or resin, left and right frame plates 1b and 1c, and a bottom frame plate 1d. It has a curtain plate 1e disposed on the upper side and a reinforcing bar 1f having a rectangular cross section disposed on the back side of the curtain plate 1e. As can be seen from FIG. 5 showing the side surface of the pachinko machine PM, the front end surface of the bottom frame plate 1d protrudes slightly forward from the front surface of the curtain plate 1e.

  The upper and lower hinge mechanisms 3 and 4 that connect the outer frame 1 and the front frame 2 so as to be opened and closed laterally are respectively provided with upper and lower hinge fittings 3a on the outer frame side provided above and below the left edge of the outer frame 1, respectively. 4a and upper and lower hinge fittings 3b and 4b on the front frame side provided above and below the left side edge of the front frame 2, for example, using the fitting of the shaft pin and the shaft hole to the front frame 1 The frame 2 is hinged so that it can be opened and closed laterally and detachable. Among these, the upper hinge metal fitting 3a on the outer frame side is L-shaped in front view (or rear view) covering the upper left corner of the outer frame 1 across the upper frame plate 1a and the left frame plate 1c that are framed at right angles. When the upper hinge metal fitting 3a is fixed to the upper left corner of the outer frame 1, the upper surface of the upper frame plate 1a and the upper surface of the upper hinge metal fitting 3a, and the side surface of the left frame plate 1c and the upper hinge metal fitting are formed. The side surfaces 3a are configured to be on the same plane. The side plate portion 3s of the upper hinge fitting 3a attached along the left frame plate 1c is formed with a rectangular hole-shaped position defining hole 3t that extends through the plate surface of the side plate portion 3s in the front-rear direction. . The position defining hole 3t will be described in detail later.

  In the manufacture of the pachinko machine PM structured as described above, the glass door 5, the ball tray assembly 7, the game ball launcher 8 and the like are attached to the front side of the front frame 2, and the tank 11 and the like are attached to the rear side of the front frame 2. A frame set WP in which the rear set board 10 with the alignment member 12, the payout mechanism 16 and the like assembled to some extent is attached, and the front frame 2 and the outer frame 1 are hinged by upper and lower hinge fittings 3a and 3b. Is supplied to an assembly plant from an external frame component supplier (frame component manufacturing plant). Further, the power supply board 14, the control board 15, and other gaming machine components are also supplied from an external component supplier to the assembly factory. The parts collected in the assembly factory are once carried into and stored in the parts warehouse, and are carried out of the parts warehouse in accordance with the production plan so that the pachinko machine PM is assembled.

  FIGS. 12 and 13 schematically show a parts transport and storage system for transporting and storing the frame parts WP from an external supplier to the assembly factory and supplying them to the assembly factory according to the production plan. The system is configured to transport and store the frame parts WP using a container cart 20 having a frame storage part (part storage part) capable of storing and holding a plurality of frame parts WP. The container cart 20 corresponds to the container cart according to the present invention, and the container cart 20 is provided with the frame component storage device according to the present invention.

  6, 7, and 8 show a front view, a right side view, and a plan view of the container cart 20 as the height of the container cart 20 is changed stepwise. As shown in the front view of the frame storage portion in a state in which the frame parts are stored, the container body 21 having a rectangular parallelepiped shape and divided into three upper and lower frames, and four attached to the lower surface of the container body 21 And a single caster wheel 22. Each stage of the container body 21 is provided with a plurality of frame storage portions 30 (this corresponds to the frame component storage device according to the present invention) aligned in the horizontal direction, and the frame component WP faces the left side downward. The container cart 20 is inserted and held in each frame storage section 30 from the front to the rear of the container cart 20 in the above-mentioned sideways posture. At least two of the four caster wheels 22 attached to the lower surface of the container main body 21 are free casters that can turn in the horizontal direction, and are provided with a stopper mechanism or a lock mechanism that prevents unintended rolling. Yes.

  As shown in FIGS. 1 and 2, the frame storage portion 30 is arranged to extend in the front-rear direction of the container main body 21 to form a lower portion of each frame storage portion 30. The guide rail 31 is constituted by an upper guide rail 37 that is supported by the container main body 21 and extends in the front-rear direction to form the upper rear portion of each frame storage portion 30. The lower guide rail 31 includes a flat plate-like lower surface rail portion 32 extending in the front-rear direction, and left and right lower guide side guide portions 33L and 33R extending in the front-rear direction by bending right and left edges of the lower surface rail portion 32 at a right angle. For example, it is formed by cutting, punching and bending a stainless steel plate or a plated steel plate having a thickness of about 1.5 to 2 mm.

  The left and right lower guide side guide portions 33L and 33R have an upward projecting height of about 10 to 20 mm, and the inner width of the left and right guide portions is lower than the left side surface on which the hinge mechanisms 3 and 4 are provided. When the upper frame plate 1a is set in a sideways posture in front, the outer width dimension of the frame part WP in this height region is set larger, and the back surface of the outer frame 1 in the sideways posture is used for the left guide. When the slide part is inserted rearward along the side guide part 33L, the structural members on the front side of the frame part WP (upper and lower hinge mechanisms 3, 4 and the glass door 5) do not contact the right guide side guide part 33R. It is like that.

  Further, the upper end portion of the right side guide portion 33R for guide is provided with a protective trim member whose surface is covered with a soft resin material (PVC, PTE, etc.) or a buffer member 33t for protecting a frame member such as a molding. Even when the frame component WP is attached / detached by tilting the frame component in the front-rear direction when the frame component WP is attached / detached, and the structural member on the front side of the frame component WP is in contact with the right side guide portion for the lower guide These contact parts are not damaged.

  The lower rail portion 32 is provided with an L-shaped rear stopper 34 that is located in the vicinity of the rear end and rises upward. A defining member 35 and a columnar lower stopper 36 which is located in front of the defining member 35 and extends in the right and left directions in parallel with the position defining member are provided.

  As shown in FIG. 8, the rear stopper portion 34 includes a stopper wall surface 34a that protrudes upward and extends to the left and right, and a guide wall surface 34b that protrudes upward and opens obliquely forward, connected to the right end of the stopper wall surface 34a. A metal plate similar to the rail 31 is processed into a sheet metal and welded and fixed to the upper surface of the lower rail portion 32. The inner surface distance between the rear portion of the guide wall surface 34b connected to the stopper wall surface 34a and the left side guide portion 33L for the lower guide is set to be slightly larger than the outer surface width in the left-right direction of the bottom frame plate 1d in the sideways posture. When the frame part WP is inserted from the front side of the frame storage unit 30 in a lying position, the guide wall surface 34b guides the rear part of the outer frame 1 to the left, and the back surface of the outer frame 1 is the left side guide for the lower guide. Guiding to be arranged along the portion 33L.

  The position defining member 35 has a cylindrical shape whose axis extends in the left-right direction, and is provided in alignment with the position defining hole 3t provided in the side plate portion of the upper hinge fitting 3a on the outer frame side. That is, even when the frame part WP is inserted along the left lower guide side guide part 33L in the above-mentioned sideways posture, even if the downward side surface (left frame plate 1c) of the outer frame rides on the position defining member 35 and moves. When the frame part WP is housed at the reference position of the frame housing part 30 without moving and being damaged smoothly on the cylindrical peripheral surface, a horizontally long pin-like position defining member 35 whose axis extends in the left-right direction is: It is set so as to be located at the center of the position defining hole 3t having a rectangular hole shape that is long in the left-right direction.

As shown in FIG. 10, a cross-sectional view as viewed in the direction of the arrow X in FIG. 9 has a width in the front-rear direction shorter than the diameter of the position defining member 35 and a length in the left-right direction. A horizontally-long rectangular fixing hole 32h that matches the axial length of the defining member 35 is formed, and the chord portion of the position defining member 35 is fitted into the fixing hole 32h and welded and fixed below the fixing hole 32h ( The height h ₁ of the axial center on the rail surface is arranged at a height position that engages with the inner peripheral surface of the opening of the position defining hole 3t. Specifically, for example, the position defined diameter as member 35 about Fai6～fai8, using a stainless pin of about 15~25mm length, height h ₁ of the axis of the rail surface, the outer frame side on the hinge bracket It is set to be disposed at a height position of about 1 to 2 mm, which is smaller than the plate thickness 2.3 to 3.2 mm of 3a.

  With such a configuration, when the frame part WP moves in the left-right direction in the front view of the container carriage and the shaft end of the position defining member 35 engages with the inner peripheral surface of the position defining hole 3t, the pressure receiving area is wide. It is possible to engage the diameter portion and receive the pressing force, and transmit the received axial pressing force to the fixing hole 32h as it is on the other end side to be dispersed. That is, according to this configuration, the axial stress σ (stress = load / pressure area) generated in both members is reduced at the engaging portion between the shaft end of the position defining member 35 and the inner peripheral surface of the position defining hole 3t. can do. Further, by inserting and fixing the position defining member 35 in the fixing hole 32h, an axial (left / right) load acting on the position defining member 35 can be received by the fixing hole 32h. Further, when the position defining member 35 is welded to the upper surface of the lower rail portion 32 without providing the fixing hole 32h, a shearing force acts on the welded portion, but the position defining member 35 is fixed as in this embodiment. This shearing force is reduced by being fitted into the hole 32h and fixed by welding, and peeling damage (welding crack) of the position defining member 35 can be prevented.

Further, the relationship in plan view between the position defining member 35 whose axis extends in the left-right direction and the position defining hole 3t having a rectangular hole shape that is long in the left-right direction is shown in FIG. As shown in FIG. 4, the position defining member 35 is positioned at the center of the position defining hole 3t in the front, rear, left, and right, and is positioned with a certain clearance in the front, rear, left, and right. It is set larger in the longitudinal direction of the clearance CL _F than CL _S. Here, in consideration of the significance of the position defining portion, if the frame component WP is firmly locked and held in the frame storage portion 30, for example, the position defining portion and the position defining hole are provided without providing the clearance as described above. It is conceivable to configure as a fitting form between the shaft pin and the shaft hole. However, in the case of such a fitting configuration, alignment when the frame component WP is accommodated in the frame accommodating portion 30 becomes complicated, and the tip of the shaft pin protruding upward may be damaged.

  Further, as will be described later, in a production system in which the frame part WP accommodated and held in the container cart 20 is taken out by the carry-out robot 65, the relative positional relationship between the container cart 20 and the carry-out robot 65 and the frames in the container cart 20 The gripping position of the frame component WP gripped by the robot hand of the transport robot 65 changes within a predetermined range due to variations in the position accuracy of the storage unit 30 and the like. For this reason, when the position defining portion and the position defining hole are fitted as described above, the frame component WP and the unloading robot 65 each time the robot hand grips the frame component WP due to the variation. The frame part WP or the unloading robot 65 may be damaged or the entire container cart 20 may be swung around.

  In this configuration, the left guide side guide portion 33L for guiding the back surface of the outer frame 1 in the sideways posture is provided, and the position defining member 35 and the position defining hole 3t are formed by a cylinder having an axis extending left and right and a square hole long to the left and right. By providing clearances in the front, rear, left, and right as an engagement form, the outer frame 1 is prevented from being damaged, and alignment when the frame component WP is accommodated in the frame accommodating portion 30 is unnecessary.

In addition, with such an engagement form, the clearance in the front-rear direction and the left-right direction can be set independently. In this embodiment, in consideration of handling by the carry-out robot 65, the clearance CL _{S in the} left-right direction is used. It is set to be larger the clearance CL _F of the front and rear direction. That is, the unloading robot 65 described later in the present embodiment clamps the robot hand by sandwiching the upper and lower intermediate positions of the upper frame plate 1a back and forth so that the frame component WP can move in the front-rear direction during clamping. The clearance CL _F is about CL _F = 3 mm, which is larger than the clearance CL _S = 1.5 mm in the left-right direction. Therefore, the position defining structure is excellent in workability and suitable for automation while having the effect of preventing the frame part WP from falling off by the engagement between the position defining member 35 and the position defining hole 3t.

The lower stopper 36 positioned in front of the position defining member 35 has a columnar shape longer than the position defining member 35, extends in parallel to the position defining member 35, and protrudes upward from the position defining member 35. ing. Specifically, a metal rod having a diameter approximately the same as that of the position defining member 35 and a length of approximately 60 to 70 mm is used, which is provided by being welded and fixed to the upper surface of the lower rail portion 32, and the height of the axis line. The position h ₂ is higher than the height position h ₁ of the axis of the position defining member 35. For this reason, even when the frame part WP is inserted into and removed from the frame storage unit 30, the outer side surface of the outer frame 1 (left frame plate 1c) can be placed on the lower stopper 36 and slid back and forth so that a smooth arc-shaped outer peripheral surface is obtained. In addition, since it slides on the support surface longer than the upper position defining portion 35, the downward side surface of the outer frame 1 is not damaged.

  Further, in the positional relationship with the position defining member 35 in the front-rear direction, when the frame part WP slides forward on the upper surface of the lower surface rail portion 32 and the position defining member 35 is engaged with the inner peripheral surface of the position defining hole 3t. In addition, the outer peripheral surface of the lower stopper 36 is set so as to come into contact with the front end surface of the outer frame 1 (the upper surface of the upper hinge fitting 3a). That is, when the frame component WP is slid forward by vibration or the like while the frame component WP is housed and held in the frame housing portion 30, the position defining member 35 and the inner peripheral surface of the position defining hole 3t are engaged. At the same time, the lower stopper 36, which is longer than these engagement lengths and has a higher engagement position, is engaged with the upper surface of the upper hinge fitting 3a, and the movement of the frame part WP is prevented. Accordingly, it is possible to reliably prevent a situation in which the frame component WP slides out and falls off the frame storage unit 30.

  On the other hand, the upper guide rail 37 is provided so as to face the rear portion of the lower guide rail 31 in the vertical direction. The upper guide rail 37 is a flat plate and extends upward and backward, and extends downward from the upper rail portion 38a and forwards. Left and right upper guide side guide portions 38L, 38R provided to extend, and inlet taper portions 38c, 38c extending outward at the front ends of the left and right upper guide side guide portions 38L, 38R, Constructed in the shape of a concave groove that opens downward. 6 to 8, a configuration example in which the right upper guide side guide portion 38R is formed of a separate member from the upper rail portion 38a and fixed with screws in order to be able to cope with the thickness change of the outer frame 1 and the like. Is shown.

  The left upper guide side guide portion 38 </ b> L is provided in position alignment on the lower guide rail 31 directly above the left lower guide side guide portion 33 </ b> L, and the lower portion of the rear surface of the outer frame 1 is positioned on the left lower guide side guide portion. When inserted rearward along 33L, the upper surface of the back surface of the outer frame 1 is contacted and supported. The right upper guide side guide portion 38R is provided at a position to support the upper surface of the outer frame 1 (specifically, the front side of the bottom plate 1d) when the frame components are stored as described above. In addition, an upper stopper 39 is provided on the rear end side of the upper rail portion 38a. The upper stopper 39 protrudes downward in alignment with the upper surface of the stopper wall surface 34a of the lower guide rail 31.

  For this reason, when the frame part WP is placed on the lower guide rail 31 in a sideways posture and the rear surface of the outer frame 1 is inserted rearward along the lower guide side guide part 33L, the frame part WP becomes a frame. The front portion (bottom frame plate 1d) of the outer frame 1 is guided by the lower guide rail side guide wall surface 34b and the upper guide rail side taper portion 38c before being completely stored in the storage portion 30, Even if the component WP is tilted in the front-rear direction and inserted obliquely rearward, the rear surface of the outer frame 1 is corrected to the reference posture along the lower guide side guide portion 33L, and the lower rear portion of the outer frame 1 is The lower guide side guide portion 33L and the guide wall surface 34b are supported, and the upper rear portion of the outer frame 1 is supported between the left and right upper guide side guide portions 38L and 38R of the upper guide rail 37. Then, when the frame part WP is accommodated in the frame accommodating part 30 and inserted to the reference position, the position defining member 35 is received in the position defining hole 3t, and the front part of the frame part WP is front, rear, left and right, the predetermined clearance described above. And is held in a lying position in a position-defined state.

In addition, in the positional relationship between the upper stopper 39 and the stopper wall surface 34a and the position defining member 35 in the front-rear direction, the frame part WP slides rearward on the upper surface of the lower rail part 32, and the position defining member 35 is inserted into the position defining hole 3t. When engaged with the inner peripheral surface, the upper stopper 39 and the stopper wall surface 34a are set so as to contact the rear end surface of the outer frame 1 (the bottom surface of the bottom frame plate 1d). For this reason, when the frame part WP is inserted rearward with the front end side of the frame part WP raised, or when the frame part WP slides rearward due to vibration or the like during the movement of the container carriage, the rear upper and lower stoppers 39. , 34a engage with the rear end surface of the outer frame 1 to prevent the frame part WP from moving. Accordingly, it is possible to reliably prevent a situation in which the frame component WP slides out and falls off the frame storage unit 30. Further, the front-rear clearance C _F between the position-defining portion 35 and the position-defining hole 3 t and the distance between the front-rear stopper and the frame part WP are set to be the same, so that the welded portion of the position-defining portion 35 is moved in the front-rear direction. It is possible to reduce the shearing force acting on the film and prevent peeling damage.

  When the frame part WP is inserted into the frame storage unit 30 in this way, the frame part WP is supported by the lower guide rail 31, the upper rear portion is held between the upper guide rail 37, and held in a sideways posture. The position defining hole 3t defines the position in the front, rear, left and right within a predetermined clearance, and the front lower stopper 36, the rear upper stopper 39, and the stopper wall surface 34a prevent the frame housing part from falling off. It is stored and held inside. The position of the center of gravity of the frame part WP is biased to the left when viewed from the front where the hinge mechanisms 3 and 4 and the ball dispensing device 16 are provided (lower side in the lying down position), and the left side surface where the hinge mechanism is provided is turned sideways.
