[0009] The embodiments of this disclosure will be described below with reference to the drawings, but this disclosure is not limited to these embodiments. The components of the embodiments described below can be combined as appropriate. In addition, some components may not be used.

[0010] (Overview of food processing machinery) Figure 1 is a schematic perspective view showing the food processing machine 1 according to the embodiment. Figure 2 is a schematic perspective view showing the movable member 11 of the loading / unloading guide board 10 according to the embodiment in the retracted position. Figure 3 is a schematic perspective view showing the movable member 11 of the loading / unloading guide board 10 according to the embodiment in the forward position.

[0011] Food processing machine 1 is a device that applies a predetermined process to a processing target object M, which is a food ingredient or food product, and is not limited by its type. The predetermined process is typically a process that applies at least one of heating and cooling to the processing target object M. Examples of food processing machine 1 include thawers, cooking machines, coolers, and sterilizers.

[0012] Food processing machine 1 includes a processing tank 2 in which the material to be processed M is contained. The processing tank 2 is provided with a door 3 that can be opened and closed. Food processing machine 1 contains the material to be processed M in the processing tank 2 and, with the door 3 of the processing tank 2 closed, performs a predetermined processing according to the type of food processing machine 1.

[0013] In the example of Fig. 1, the food machine 1 is a vacuum cooler. In this case, the food machine 1 includes the above-described treatment tank 2, a decompression means for discharging the gas in the treatment tank 2 to the outside and decompressing the inside of the treatment tank 2, a recompression means for introducing outside air into the decompressed treatment tank 2 to recompress the inside of the treatment tank 2, and a control means for controlling each means. The food machine 1 vacuum-cools the object to be treated M by decompressing the inside of the treatment tank 2 with the decompression means in a state where the door 3 of the treatment tank 2 containing the object to be treated M is hermetically closed. After vacuum cooling, the food machine 1 recompresses the inside of the treatment tank 2 to atmospheric pressure with the recompression means. After recompression, the door 3 of the treatment tank 2 can be opened to carry out the object to be treated M from the inside of the treatment tank 2.

[0014] In the example of Fig. 1, the treatment tank 2 includes a treatment tank main body 4 having an in-store entrance 4A on the front surface, and a door 3 that slides in the width direction to open and close the in-store entrance 4A of the treatment tank main body 4. The in-store entrance 4A is an opening formed in the treatment tank main body 4. Through the in-store entrance 4A, the object to be treated M can be taken in and out together with the cart 5 in the treatment tank main body 4.

[0015] The treatment tank main body 4 is formed in a substantially rectangular hollow box shape. The method of transporting the object to be treated M is not particularly limited, and in addition to the illustrated cart 5, a wagon, a cart, etc. may also be used. The object to be treated M does not necessarily have to be transported by a traveling device such as a cart 5, a wagon, or a cart, and may be transported using a container that can be carried by an operator by hand.

[0016] The door 3 is formed in a substantially rectangular plate shape and opens and closes the in-store entrance 4A on the front surface of the treatment tank main body 4. In the example of Fig. 1, the door 3 is suspended so as to be slidable left and right by a suspension rail 2A provided at the upper part of the treatment tank main body 4. The door 3 can fully open the in-store entrance 4A of the treatment tank main body 4 and fully close the in-store entrance 4A by sliding movement. Note that the sliding of the door 3 is manually performed by gripping the handle 3A, but the door 3 may be automatically operated by a drive source such as an electric motor. Also, a packing 2B is provided at a position surrounding the in-store entrance 4A in the treatment tank 2. The packing 2B seals the gap between the treatment tank main body 4 and the door 3 when the door 3 is closed.

[0017] In front of the floor before the in-warehouse entrance 4A of the processing tank 2, a drain pit (groove) 6 is provided along the edge on the inlet side of the processing tank main body 4. The drain pit 6 receives, for example, water discharged from the in-warehouse entrance 4A during cleaning inside the processing tank 2.

[0018] When loading and unloading the object to be processed M with respect to the processing tank main body 4, the cart 5 passes over the drain pit 6. To assist the cart 5 in passing over the drain pit 6, a loading / unloading guide plate 10 serving as a traveling path for the cart 5 and the operator is provided.

[0019] The loading / unloading guide plate 10 is installed at a position facing the in-warehouse entrance 4A of the food machine 1 and is a loading / unloading guide plate that provides a traveling path for loading and unloading the object to be processed M into and out of the food machine 1. The loading / unloading guide plate 10 provides a traveling path that spans from the floor surface on the front side of the drain pit 6 across the drain pit 6 to the in-warehouse floor surface 4B inside the processing tank main body 4. Thereby, the loading / unloading guide plate 10 enables the cart 5 to travel over the drain pit 6. The loading / unloading guide plate 10 can move horizontally (toward the front side) to a position away from the movement path of the door 3. Thereby, the loading / unloading guide plate 10 can retract to a position where it does not interfere with the door 3 when the door 3 is opened and closed.

[0020] There are typically two installation configurations for the food processing machine 1. The first configuration involves excavating a portion of the floor and installing the processing tank 2 in a location lower than the surrounding floor surface, so that the interior floor surface 4B of the processing tank body 4 is at the same height as the exterior floor surface of the processing tank body 4. The second configuration involves installing the processing tank body 4 at the same height as the surrounding floor surface without any special excavation, so that the interior floor surface 4B of the processing tank body 4 is positioned higher than the exterior floor surface of the processing tank body 4. In the first configuration, where the interior floor surface 4B of the processing tank body 4 is at the same height as the exterior floor surface of the processing tank body 4, the loading / unloading guide board 10 is stretched across the interior floor surface 4B and the floor surface in an almost horizontal position. In the second configuration, where the interior floor 4B of the processing tank body 4 is higher than the exterior floor of the processing tank body 4, the loading / unloading guide board 10 is laid out in a slope-like manner, sloping diagonally upward from the floor towards the interior floor 4B. The loading / unloading guide board 10 may be used in either installation configuration, but in this embodiment, the first installation configuration will be used as an example for explanation.

[0021] (Structure of loading / unloading guide signs) As shown in Figures 2 and 3, the loading / unloading guide board 10 comprises a movable member 11 and a fixed member 12 that supports the movable member 11 so that it can move in the front-rear direction.

[0022] Hereinafter, the direction of movement of the movable member 11 relative to the fixed member 12 will be defined as the front-to-back direction of the loading / unloading guide board 10. The movable member 11 can move forward relative to the fixed member 12, extending forward from above the fixed member 12 to its forward limit. From its forward limit, the movable member 11 can move backward relative to the fixed member 12, extending backward to its backward limit above the fixed member 12. Of the front-to-back directions, the direction in which the movable member 11 extends relative to the fixed member 12 is defined as the front, and the opposite direction is defined as the rear. Furthermore, the direction perpendicular to the front-to-back direction in the horizontal plane will be defined as the left-to-right direction or the width direction.

[0023] The loading / unloading guide board 10 is positioned facing the interior entrance 4A of the treatment tank 2 via the drainage pit 6. The loading / unloading guide board 10 is installed on the installation surface 7, which is the floor surface near the treatment tank 2. The loading / unloading guide board 10 is installed so that its front faces the interior entrance 4A of the treatment tank 2. Therefore, in the installed state, the front of the loading / unloading guide board 10 is in the direction in which the movable member 11 approaches the treatment tank 2, and the rear is in the direction in which the movable member 11 moves away from the treatment tank 2.

[0024] As shown in Figure 3, the loading / unloading guide board 10 has its maximum length in the front-to-back direction when the movable member 11 is at its forward limit. When the movable member 11 moves forward, the loading / unloading guide board 10 crosses over the drain pit 6 and reaches the entrance 4A inside the storage area. As a result, the trolley 5 can pass over the loading / unloading guide board 10 and travel into the storage area of ​​the treatment tank 2 without being obstructed by the drain pit 6.

[0025] As shown in Figure 2, the loading / unloading guide plate 10 is moved backward by the retraction of the movable member 11, so that the movable member 11 is moved behind the drain pit 6. As a result, the loading / unloading guide plate 10 does not obstruct the movement of the door 3 when opening and closing the door 3 of the treatment tank 2.

[0026] <Fixing components> The fixing member 12 supports the movable member 11 so that it can move in the front-rear direction. The fixing member 12 is fixedly installed on the floor surface, which is the installation surface 7, at a position in front of the drain pit 6. As shown in Figure 3, the fixing member 12 includes a guide plate 20 that extends along the front-rear direction. The fixing member 12 supports the movable member 11 so that it can move in the front-rear direction by the guide plate 20.

[0027] In this embodiment, the fixing member 12 includes a fixing frame 21 on which a guide plate 20 is provided, and a blocking member 22.

[0028] The fixed frame 21 has a pair of support parts 23 and a fixed plate part 24. The pair of support parts 23 are arranged facing each other with a gap between them in the left-right direction. The fixed plate part 24 is a flat plate member that extends in the left-right direction and is installed along the installation surface 7 of the fixed member 12. The fixed plate part 24 is provided in the left-right direction, extending from the area between the pair of support parts 23 to the areas on both sides of the pair of support parts 23. Bolt insertion holes 24A are provided at both ends of the fixed plate part 24 in the left-right direction for attaching the fixed frame 21 to the installation surface 7 with bolts. Note that in Figures 1 to 3, for convenience, the bolts for attaching the fixed frame 21 to the installation surface 7 are not shown. The pair of support parts 23 are provided on the upper surface of the fixed plate part 24. Of the fixed plate part 24, the area between the pair of support parts 23 is the area where the movable member 11 is placed and constitutes part of the path of the loading / unloading guide board 10.

[0029] Each of the pair of support parts 23 supports the movable member 11. The pair of support parts 23 are positioned on both the left and right outer sides of the movable member 11. The fixed member 12 supports the movable member 11 from both sides in the left and right directions, which are perpendicular to the front and rear directions. Since the structure of the pair of support parts 23 is substantially the same except that it is symmetrical, the structure of the left support part 23 will be described below.

[0030] Figure 4 is an enlarged perspective view showing the left end of the loading / unloading guide board 10 when the movable member 11 is at its retracted limit. Figure 5 is an enlarged perspective view showing the left end of the loading / unloading guide board 10 when the movable member 11 is in motion. Figure 6 is an enlarged perspective view showing the left end of the loading / unloading guide board 10 when the movable member 11 is at its forward limit.

[0031] As shown in Figures 4 to 6, the support portion 23 has a plate-like shape that rises upward from the installation surface 7 and extends along the front-rear direction. Guide plates 20 are provided on the side of the support portion 23 that faces the side portion 31A of the movable member 11 in the left-right direction. The support portion 23 supports the left-right ends of the movable member 11 with the guide plates 20. The guide plates 20 support the movable member 11 so that it can move in the front-rear direction and guide the movement of the movable member 11.

[0032] The guide plate 20 is a plate-shaped member provided so as to protrude from the support portion 23 toward the center in the left-right direction. The guide plate 20 provides a surface on which the rolling elements (first rolling element 33 and second rolling element 34) of the movable member 11, which will be described later, roll. The upper surface of the guide plate 20 becomes the surface for the first rolling element 33, and the lower surface of the guide plate 20 becomes the surface for the second rolling element 34. As the rolling elements roll on the guide plate 20, the movable member 11 moves in the front-rear direction. The detailed structure of the guide plate 20 will be described later.

[0033] The rear end of the support portion 23 is provided with a mounting portion 25 for detachably attaching the blocking member 22.

[0034] The retaining member 22 is a stopper that prevents the movable member 11 from detaching from the fixed member 12. The retaining member 22 is detachably mounted on the fixed frame 21. Specifically, as shown in Figure 3, one retaining member 22 is provided for each pair of support parts 23. The retaining member 22 is fastened to the mounting part 25 at the rear end of the support part 23 by bolts 26 and nuts. Therefore, the retaining member 22 can be removed from the fixed frame 21 (support part 23) by loosening the bolts 26.

[0035] The blocking member 22 has a plate-like shape that rises upward from the installation surface 7. The blocking member 22 includes a blocking plate portion 22A that extends in the left-right direction and a guide plate portion 22B that extends diagonally from the blocking plate portion 22A. When viewed from above, the blocking member 22 is a flat plate member with a roughly V-shape.

[0036] The blocking plate portion 22A is provided with an insertion hole for attachment to the support portion 23 by a bolt 26. When attached to the mounting portion 25 of the support portion 23, the blocking plate portion 22A extends toward the center in the left-right direction and reaches the position of the movable member 11 in the left-right direction. The blocking plate portion 22A is provided behind the rear end of the guide plate 20. The blocking plate portion 22A faces the rear end of the movable member 11 (the end of the side portion 31A) in the front-rear direction. As a result, the blocking member 22 contacts the rear end of the movable member 11, preventing the movable member 11 from detaching from the fixing member 12. The position where the rolling element contacts the blocking member 22 becomes the limit of the movable member 11's retraction.

[0037] For example, during cleaning or maintenance, removing the blocking member 22 from the support part 23 removes the blocking member 22 from the rear of the guide plate 20, allowing the movable member 11 to be pulled out from the fixed member 12 and separated. By simply removing the two blocking members 22, the movable member 11 can be removed from the fixed member 12 and thoroughly washed.

[0038] The guide plate section 22B is positioned at the rear end of the loading / unloading guide board 10. In other words, the guide plate section 22B is positioned at the entrance to the path formed by the loading / unloading guide board 10. The guide plate section 22B extends diagonally from the left-right inner end (the central side of the fixing member 12) of the blocking plate section 22A toward the rear and outward in the left-right direction. As a result, as shown in Figures 2 and 3, in the blocking members 22 attached to each of the pair of support sections 23, the distance between the guide plate sections 22B gradually narrows from the rear toward the front. The rear end of the guide plate section 22B is located further outward in the left-right direction than the side portion 31A of the movable member 11. The front end of the guide plate section 22B (the connection portion with the blocking plate section 22A) is located at the same position as the side portion 31A of the movable member 11, or further inward in the left-right direction than the side portion 31A.

[0039] As a result, the guide plate section 22B functions as a guide that directs the trolley 5 towards the center of the track when the trolley 5 enters the track of the loading / unloading guide plate 10.

[0040] <Movable parts> As shown in Figures 2 and 3, the movable member 11 includes a support plate portion 30, a sliding portion 31, and an operating portion 32.

[0041] The support plate portion 30 constitutes the bottom of the movable member 11 and is a plate-shaped portion that extends in the front-rear and left-right directions. The support plate portion 30 serves as a path for the movable member 11. The support plate portion 30 is positioned above the fixed plate portion 24 between a pair of support portions 23 of the fixed member 12.

[0042] The sliding parts 31 are provided one at each end of the movable member 11 in the left-right direction, i.e., a pair. The pair of sliding parts 31 are positioned between the pair of support parts 23 of the fixed member 12. The left sliding part 31 faces the left support part 23 in the left-right direction, and the right sliding part 31 faces the right support part 23 in the left-right direction. The pair of sliding parts 31 are supported by the pair of support parts 23 so as to be movable in the front-rear direction. The pair of sliding parts 31 are provided with a first rolling element 33 and a second rolling element 34, respectively, as shown in Figures 4 to 6.

[0043] Since the structure of the pair of sliding parts 31 is substantially identical except for being symmetrical, the structure of the left sliding part 31 will be described below. Figure 7 is a schematic cross-sectional view of the support part 23 and the sliding part 31 as seen from the front and rear directions.

[0044] The sliding portion 31 has a side portion 31A that rises upward from the left-right ends of the support plate portion 30, and a protruding portion 31B that bends from the upper end of the side portion 31A and extends outward in the left-right direction. The side portion 31A faces the support portion 23 of the fixing member 12 in the left-right direction. The first rolling element 33 and the second rolling element 34 are rotatably mounted on the outer surface of the side portion 31A via a rotating shaft 31C that protrudes outward in the left-right direction.

[0045] The first rolling element 33 and the second rolling element 34 are arranged to sandwich the guide plate 20 from above and below. The first rolling element 33 is positioned on the upper side of the guide plate 20. The first rolling element 33 rolls along the upper surface of the guide plate 20. The second rolling element 34 is positioned on the lower side of the guide plate 20. The second rolling element 34 rolls along the lower surface of the guide plate 20. When an external force in the front-rear direction acts on the movable member 11, the first rolling element 33 and the second rolling element 34 roll along the guide plate 20. This causes the movable member 11 to move in the front-rear direction. The first rolling element 33 and the second rolling element 34 are composed of rollers with low rolling resistance, such as bearings. By rolling, the first rolling element 33 and the second rolling element 34 reduce the resistance when moving the movable member 11 in the front-rear direction, allowing the movable member 11 to move with a small external force.

[0046] As shown in Figure 7, the fixed member 12 supports the movable member 11 by guide plates 20 that contact the first rolling element 33. That is, the movable member 11 is supported from below by the guide plates 20 on both sides in the left-right direction, with the first rolling element 33 resting on the guide plates 20. At least a portion of the guide plates 20, including the rear end portion, is positioned at a height such that the bottom surface 11A of the movable member 11 is above the bottom surface 12A of the fixed member 12. The bottom surface 11A of the movable member 11 is the bottom surface of the support plate portion 30. The bottom surface 12A of the fixed member 12 is the bottom surface of the fixed plate portion 24. In other words, when the movable member 11 is at its retraction limit (the state in Figure 7), the support plate portion 30 of the movable member 11 is positioned above the installation surface 7.

[0047] In this embodiment, when the movable member 11 is at its retracted limit, the support plate portion 30 is positioned above the upper surface of the fixed plate portion 24. As a result, a gap CL is formed in the vertical direction between the support plate portion 30 and the fixed plate portion 24. The movable member 11 is supported by the support portion 23 with its bottom surface 11A not in contact with the fixed plate portion 24 (and the installation surface 7). This allows the movable member 11 to move in the front-rear direction without its bottom surface 11A sliding against the fixed plate portion 24, thereby reducing resistance to movement.

[0048] As shown in Figures 2 and 3, the operating unit 32 receives operations for moving the movable member 11. The loading / unloading guide board 10 according to this embodiment does not have a drive source (actuator) that applies external force to the movable member 11, and the movable member 11 is moved manually by the operator applying external force. The operating unit 32 is provided either integrally with the support plate 30 or separately. In this embodiment, the operating unit 32 is integral with the support plate 30. This allows the operator to move the support plate 30 by grasping the operating unit 32 with their hand and applying external force.

[0049] The operating section 32 is provided in pairs, one at each end of the movable member 11 in the left-right direction. Specifically, the operating section 32 extends upward from each slide section 31 and has a handrail-like shape. The operating section 32 extends upward from the upper surface of the protruding portion 31B (see Figure 4) of the slide section 31. The operating section 32 is formed from an inverted U-shaped columnar member. That is, the operating section 32 is constructed by fixing both ends of an inverted U-shaped columnar member to the upper surface of the protruding portion 31B. The operating section 32 is provided from near the rear end to near the front end of the movable member 11. A gripping portion 32A is formed at the top of the operating section 32, extending almost horizontally along the front-rear direction. By grasping the gripping portion 32A, the operator can apply an external force to move the movable member 11 in the front-rear direction. The gripping portion 32A is positioned at a height approximately to the waist of an average-height adult. The operating section 32 is shaped like a handrail, so it also functions as a safety device that workers can grab onto if they trip or fall.

[0050] As described above, the operating unit 32 according to this embodiment is provided integrally with the support plate 30 and moves together with the support plate 30 due to external force. The operating unit 32 is an operating unit for the operator to operate the movable member 11 by hand, but the operator can also move the movable member 11 with their foot by stepping on the support plate 30 and pushing it forward. The support plate 30 also functions as an operating unit 35 for the operator to operate the movable member 11 with their foot. In other words, the loading / unloading guide board 10 according to this embodiment includes an operating unit 32 that can be operated by the operator by hand and an operating unit 35 that can be operated by the operator with their foot.

[0051] Furthermore, the operating units 32 and 35 may be input devices such as switches for moving the movable member 11 with an actuator. In that case, the operating units 32 and 35 may be provided separately from the support plate 30. The operating units 32 and 35 may be switches operated by hand, foot switches, or non-contact switches using optical sensors or the like. Examples of actuators include electric motors, fluid pressure cylinders, solenoids, and electromagnetic actuators such as linear motors. In this case, the operating unit 32 or operating unit 35 outputs a signal corresponding to the operation input, and the actuator moves the movable member 11 by operating in accordance with the output signal.

[0052] <Detailed structure of the guide board and rolling element> Next, the detailed structure of the guide plate 20 and rolling elements (first rolling element 33, second rolling element 34) according to the embodiment will be described. Figure 8 is a schematic cross-sectional view showing the guide plate 20 and rolling elements when the movable member 11 is at its retracted limit. Figure 9 is a schematic cross-sectional view showing the guide plate 20 and rolling elements when the movable member 11 is at its forward limit. Note that Figures 8 and 9 show a cross-section of the loading / unloading guide plate 10 viewed from near the center toward the left, but since the guide plate 20 and rolling elements are hidden by the side portion 31A of the movable member 11, the side portion 31A is shown with a dotted line outlining only for convenience.

[0053] As shown in Figures 8 and 9, the guide plate 20 according to this embodiment has an inclined portion 41 and a resistance-applying portion 42. In this embodiment, the guide plate 20 includes a plurality of auxiliary plates 43, 44, and 45 in the inclined portion 41.

[0054] The inclined section 41 is inclined downward at the front end PF of the guide board 20. That is, the guide board 20 is inclined so as to slope downward toward the front from the bend point BP just before the front end PF, and the section between the bend point BP and the front end PF constitutes the inclined section 41. For this reason, in front of the bend point BP of the guide board 20, the first rolling element 33 is guided to roll diagonally downward along the inclined section 41.

[0055] Auxiliary plates 43, 44, and 45 are guide plates that assist the movement of the rolling elements in the inclined portion 41 of the guide plate 20. Like the guide plate 20, the auxiliary plates 43, 44, and 45 are provided on each of the pair of support portions 23 of the fixed frame 21. The auxiliary plates 43, 44, and 45 are inclined at the same inclination angle as the inclined portion 41.

[0056] Auxiliary plate 43 is positioned on the underside of guide plate 20. The underside of auxiliary plate 43 forms the surface for the second rolling element 34 in the inclined section 41. Auxiliary plate 44 is positioned at a distance from the underside of auxiliary plate 43. When the first rolling element 33 enters the inclined section 41, the second rolling element 34 enters the space between the underside of auxiliary plate 43 and the upper surface of auxiliary plate 44. The second rolling element 34 rolls along the underside of auxiliary plate 43. Auxiliary plate 45 is positioned at a distance from the upper side of guide plate 20. The first rolling element 33, having entered the inclined section 41, moves between the upper surface of guide plate 20 and the underside of auxiliary plate 45. These auxiliary plates 43, 44, and 45 ensure that the rolling elements move reliably along the inclined section 41, even when an operator attempts to lift and move the movable member 11 against the force of gravity.

[0057] The resistance-applying section 42 is located behind the center CP in the front-rear direction of the guide plate 20. The resistance-applying section 42 applies forward movement resistance (a resistance force that prevents forward movement) to the movable member 11 by contacting at least one of the first rolling element 33 and the second rolling element 34.

[0058] As shown in Figure 8, in this embodiment, the resistance-applying portion 42 is provided in a range that includes the position of the first rolling element 33 when the movable member 11 is at its retracted limit. In the example in Figure 8, the resistance-applying portion 42 is composed of an inclined surface that slopes upward toward the front. The inclination of the resistance-applying portion 42 is very small, and is less inclined than the inclined portion 41 at the front end. Therefore, in the guide plate 20, the portion between the resistance-applying portion 42 and the bending point BP (second portion 20B) is positioned slightly higher than the portion behind the resistance-applying portion 42 (first portion 20A).

[0059] When moving the movable member 11 forward from the state where it is at its retraction limit (the state in Figure 8), the first rolling element 33 must overcome the inclination of the resistance-applying section 42, thus creating resistance. In this way, the resistance-applying section 42 applies a resistance force to the forward movement of the movable member 11, thereby preventing the movable member 11 from moving forward against the operator's will. The inclination of the resistance-applying section 42 is such that the first rolling element 33 can easily overcome the resistance-applying section 42 when the operator intentionally applies an external force to move forward.

[0060] Thus, the guide plate 20 according to this embodiment can be divided into three regions: a first portion 20A from the rear end PR to the resistance-applying portion 42, a second portion 20B from the resistance-applying portion 42 to the bending point BP, and an inclined portion 41 from the bending point BP to the front end PF. The first portion 20A and the second portion 20B are substantially horizontal (parallel to the installation surface 7). Substantially parallel means that even if there is an angle difference that inevitably arises due to the influence of tolerances, etc., they are considered to be parallel.

[0061] As shown in Figures 8 and 9, the first rolling element 33 and the second rolling element 34 are positioned offset from each other in the front-rear direction. The second rolling element 34 is positioned behind the first rolling element 33. When a moment is generated that causes the movable member 11 to tilt forward around the first rolling element 33, the second rolling element 34 is supported by the lower surface of the guide plate 20, preventing the movable member 11 from tilting. This prevents the front end 30F of the support plate portion 30 from tilting downward when the movable member 11 is moved forward, thus preventing it from coming into contact with the interior floor surface 4B of the processing tank body 4.

[0062] The first rolling element 33 and the second rolling element 34 are both positioned behind the center CP in the front-rear direction of the guide plate 20 at the position that is the retraction limit of the movable member 11. This allows for a larger amount of movement to reach the forward limit. In the examples of Figures 8 and 9, the amount of movement of the movable member 11 from the retraction limit to the forward limit is approximately equal to the length of the fixed plate portion 24 in the front-rear direction.

[0063] As shown in Figure 9, the support plate portion 30 makes contact with both the floor surface, which is the installation surface 7 of the fixing member 12, and the interior floor surface 4B of the food processing machine 1, as the first rolling element 33 and the second rolling element 34 are guided down by the inclined portion 41.

[0064] In other words, the amount of descent H (difference in height) of the inclined portion 41 from the bending point BP to the front end PF is greater than the vertical distance between the bottom surface 11A of the movable member 11 and the bottom surface 12A of the fixed member 12 (i.e., the installation surface 7) when the first rolling element 33 is at the bending point BP. Therefore, as the movable member 11 descends along the inclined portion 41 of the guide plate 20, the bottom surface 11A of the movable member 11 (the lower surface of the support plate portion 30) touches the installation surface 7 before the first rolling element 33 reaches the front end PF of the guide plate 20. The contact of the bottom surface 11A prevents the movable member 11 from advancing any further. As described above, in this embodiment, a part of the floor is excavated so that the interior floor surface 4B of the food processing machine 1 is at the same height as the floor surface which is the installation surface 7. Therefore, when the bottom surface 11A of the movable member 11 touches the installation surface 7, the tip of the bottom surface 11A touches the interior floor surface 4B. The state shown in Figure 9 is when the movable member 11 is in its forward position.

[0065] When the movable member 11 is in its forward position, the bottom surface 11A of the movable member 11 touches the ground with the first rolling element 33 in the middle of the inclined section 41, so the movable member 11 is supported by the installation surface 7 and the interior floor surface 4B.

[0066] When the first rolling element 33 is on the inclined section 41, the first rolling element 33 is biased forward by the action of gravity. Therefore, when moving the movable member 11 backward from the state where the movable member 11 is at its forward limit (the state in Figure 9), it is necessary to overcome the inclination of the inclined section 41, which acts as resistance. In this way, the inclined section 41 provides resistance to the backward movement of the movable member 11, thereby preventing the movable member 11 from moving backward against the operator's will.

[0067] When the movable member 11 is in its forward position, the fixed plate portion 24 of the fixed member 12 and the support plate portion 30 of the movable member 11 are aligned in the front-rear direction on the installation surface 7. This forms a track that spans the drainage pit 6. In this embodiment, the track is composed of the upper surface of the fixed plate portion 24 and the upper surface of the support plate portion 30.

[0068] Furthermore, the thickness of the fixing plate portion 24 of the fixed member 12 and the thickness of the support plate portion 30 of the movable member 11 are substantially the same. Substantially the same means that even if there are unavoidable dimensional differences due to the effects of dimensional tolerances, etc., they are considered to be the same. Therefore, when the bottom surface 11A of the movable member 11 is in contact with the installation surface 7 at its forward limit, the upper surface of the fixing plate portion 24 and the upper surface of the support plate portion 30 are substantially the same plane (i.e., flush). As a result, no step is formed on the track, and the trolley 5 can run smoothly. However, a step may be formed if the thickness of the fixing plate portion 24 and the thickness of the support plate portion 30 are different.

[0069] Furthermore, in this embodiment, the front end 24F of the fixing plate portion 24 and the rear end 30R of the support plate portion 30 are inclined diagonally downward toward the front. When the bottom surface 11A is in contact with the installation surface 7, the inclined surface of the rear end 30R of the support plate portion 30 rests on the inclined surface of the front end 24F of the fixing plate portion 24. This reduces the gap at the joint between the front end 24F of the fixing plate portion 24 and the rear end 30R of the support plate portion 30, thereby reducing the resistance when the trolley 5 is running.

[0070] The rear end 24R of the fixing plate portion 24 is inclined to slope downward toward the rear. This reduces the height difference between the rear end 24R of the fixing plate portion 24 and the installation surface 7. As a result, resistance and impact when the trolley 5 moves between the floor surface and the track of the loading / unloading guide board 10 can be reduced.

[0071] Furthermore, the front end 30F of the support plate portion 30 is inclined to slope downward toward the front. This reduces the height difference between the front end 30F of the support plate portion 30 and the interior floor 4B of the food processing machine 1. As a result, resistance and impact can be reduced when the trolley 5 moves from the loading / unloading guide board 10 into the interior of the food processing machine 1, and when the trolley 5 moves from the interior onto the loading / unloading guide board 10.

[0072] (Operation of loading / unloading guide signs) Next, the operation of the loading / unloading guide board 10 according to this embodiment will be described.

[0073] Except when loading or unloading materials M to be processed into or out of the processing tank 2 of the food processing machine 1, the loading / unloading guide board 10 is kept in a position where the movable member 11 is at its retracted limit. When the movable member 11 is at its retracted limit, the resistance-applying unit 42 prevents the movable member 11 from moving forward unintentionally.

[0074] When loading or unloading the material to be processed M, the worker opens the door 3 of the processing tank 2, as shown in Figure 1. This opens the interior of the processing tank 2.

[0075] Next, the operator moves the movable member 11 forward. The operator can move the movable member 11 forward by gripping the gripping portion 32A of the operating portion 32 and applying force forward. Alternatively, the operator can move the movable member 11 forward by stepping on the support plate portion 30, which serves as the operating portion 35, and applying force forward.

[0076] From the state shown in Figure 4, when an external force sufficient to allow the first rolling element 33 to overcome the resistance-applying section 42 is applied to the movable member 11, the first rolling element 33 overcomes the resistance-applying section 42 and moves forward, causing the movable member 11 to move forward relative to the fixed member 12, as shown in Figure 5. At this time, the moment that would cause the movable member 11 to tilt forward is supported by the lower surface of the guide plate 20 via the second rolling element 34, so the movable member 11 can move forward without tilting. While the first rolling element 33 moves along the first section 20A and the second section 20B of the guide plate 20, the movable member 11 is located above the fixed plate section 24, so no sliding resistance is generated between the fixed member 12 and the fixed plate section 24, and the fixed member 12 can move forward easily without the operator applying a large external force.

[0077] As the first rolling element 33 moves forward, passing the bend point BP of the guide plate 20, the first rolling element 33 rolls along the slope of the inclined section 41. As a result, the movable member 11 moves forward while descending along the inclined section 41. Consequently, as shown in Figures 3, 6, and 9, the movable member 11 reaches its forward limit and stops after the front end 30F of the support plate section 30 enters the chamber of the processing tank 2, and then makes contact with both the floor surface which is the installation surface 7 and the interior floor surface 4B of the food processing machine 1.

[0078] As shown in Figure 9, at the forward limit, the movable member 11 spans the drain pit 6 and is positioned between the floor surface, which is the installation surface 7, and the interior floor surface 4B of the food processing machine 1. This creates a path for the loading / unloading guide board 10 from outside the food processing machine 1, passing over the drain pit 6 and into the interior. The movable member 11 is biased forward by the inclined portion 41, so it is held in the forward limit position without the operator having to apply force.

[0079] The worker moves the trolley 5 onto the track of the loading / unloading guide board 10. First, the worker drives the trolley 5 onto the upper surface of the fixing plate portion 24 of the fixing member 12. At this time, even if the front of the trolley 5 is slightly off from the fixing plate portion 24, it is guided onto the fixing plate portion 24 by the guide plate portion 22B of the blocking member 22. After the trolley 5 is on top of the fixing plate portion 24, the worker drives the trolley 5 forward, passing it through the support plate portion 30 of the movable member 11 into the chamber of the processing tank 2.

[0080] Once the trolley 5 has been brought into the processing tank 2, the operator grasps the gripping part 32A of the operating unit 32 and applies force backward to move the movable member 11 backward. To move the movable member 11 backward from its forward limit, the operator lifts the movable member 11 diagonally upward along the inclined section 41. The operator may also operate the operating unit 35 with their foot. If the first rolling element 33 continues to move backward after crossing the inclined section 41, the rear end of the movable member 11 comes into contact with the stopping plate 22A of the stopping member 22, causing the movable member 11 to reach its backward limit and stop. As a result, the movable member 11 moves backward from the movement path of the door 3, making it possible to close the door 3.

[0081] After closing door 3, the worker operates food processing machine 1 to process the material M contained inside processing tank 2. After processing, the worker forms a path for loading / unloading guide board 10 using the same procedure as when loading, then removes the trolley 5 from inside the warehouse, moves the movable member 11 to its rear limit, and then closes door 3. In this manner, the path for loading / unloading guide board 10 and the loading / unloading of material M can be performed.

[0082] When cleaning the loading / unloading guide board 10, the worker removes the bolts 26 of the blocking members 22 and detaches each blocking member 22 from the fixed frame 21, and then moves the movable member 11 backward from its backward limit. The sliding part 31 of the movable member 11 is pulled backward from the support part 23 of the fixed frame 21, separating the movable member 11 from the fixed member 12. This allows the worker to separate the movable member 11 and the fixed member 12 and clean them separately, which is hygienic. In addition, the sliding part 31 (rolling element) of the movable member 11 and the support part 23 (guide board 20) of the fixed member 12 can also be cleaned directly, so foreign matter that may obstruct the movement of the rolling elements can be easily removed, and the smooth movement of the movable member 11 can be maintained.

[0083] After cleaning, the worker moves the movable member 11 so that the sliding part 31 of the movable member 11 is inserted forward from the rear of the support part 23, and positions the first rolling element 33 and the second rolling element 34 on the upper and lower sides of the guide plate 20, respectively. After that, the worker fixes each blocking member 22 to the mounting part 25 of the support part 23.

[0084] [effect] As described above, the loading / unloading guide board 10 of the food processing machine 1 of this embodiment is installed in a position facing the interior entrance 4A of the food processing machine 1 and is a loading / unloading guide board that provides a path for loading and unloading the object to be processed M into and out of the interior of the food processing machine 1, and comprises a movable member 11 including a support plate portion 30 that serves as a path, an operating portion 32 provided integrally with or separately from the support plate portion 30 and receiving operations for movement, and a fixed member 12 that supports the movable member 11 so as to be movable in the front-rear direction, the fixed member 12 including a guide plate 20 extending along the front-rear direction, and the movable member 11 having a first rolling element 33 that rolls on the upper surface of the guide plate 20 and a second rolling element 34 that rolls on the lower surface of the guide plate 20.

[0085] With this configuration, since the movable member 11 has an operating unit 32, the movable member 11 can be operated simply by inputting to the operating unit 32. Therefore, a connecting structure, such as when linking the door 3 of the food processing machine 1 with the movable member 11, is unnecessary, thus simplifying the structure of the loading / unloading guide board 10. In addition, since the movable member 11 operates by rolling the first rolling element 33 and the second rolling element 34, which are arranged above and below the guide board 20 of the fixed member 12, the use of complex-shaped parts such as gears can be reduced, simplifying the structure for moving the movable member 11. As a result, a loading / unloading guide board 10 with a simple structure and easy cleaning can be provided.

[0086] Furthermore, in this embodiment, the fixing member 12 includes a fixing frame 21 on which a guide plate 20 is provided, and a blocking member 22 that is detachably provided on the fixing frame 21 and prevents the movable member 11 from detaching from the fixing member 12 by contacting the rear end of the movable member 11. In this configuration, the blocking member 22 prevents the movable member 11 from unintentionally detaching from the fixing frame 21, and the movable member 11 can be separated from the fixing frame 21 by removing the blocking member 22 from the fixing frame 21. Therefore, by separating the movable member 11, the movable member 11 can be easily and thoroughly cleaned, thus achieving high hygiene standards.

[0087] Furthermore, in this embodiment, both the first rolling element 33 and the second rolling element 34 are positioned behind the center CP in the front-rear direction of the guide plate 20 at the position that is the retraction limit of the movable member 11. In this configuration, the travel distance to the forward limit can be increased compared to when either rolling element is positioned in front of the center. Since the travel distance of the movable member 11 can be increased, the front-rear dimensions of the movable member 11 and the fixed member 12 can be reduced accordingly. The loading / unloading guide plate 10 can be made more compact, which facilitates cleaning work.

[0088] Furthermore, in this embodiment, the guide plate 20 has a resistance-applying part 42 located behind the center CP in the front-rear direction, which contacts at least one of the first rolling element 33 and the second rolling element 34 to provide resistance to the movable member 11 moving forward. With this configuration, the resistance-applying part 42 can prevent the movable member 11 from unintentionally moving forward towards its forward limit.

[0089] Furthermore, in this embodiment, the fixed member 12 supports the movable member 11 by a guide plate 20 that contacts the first rolling element 33, and at least a portion of the guide plate 20, including the rear end portion, is provided at a height such that the bottom surface 11A of the movable member 11 is above the bottom surface 12A of the fixed member 12. In this configuration, the guide plate 20 supports the movable member 11 in an elevated position while guiding its movement in the front-rear direction. As a result, the sliding resistance when the movable member 11 moves can be reduced, and the movable member 11 can be moved smoothly with less force.

[0090] Furthermore, in this embodiment, the guide plate 20 has an inclined portion 41 that is inclined downward at its front end PF. In this configuration, the movable member 11 can be lowered diagonally along the inclined portion 41 and brought closer to the interior floor surface 4B of the food processing machine 1. This reduces the height difference between the support plate portion 30 and the interior floor surface 4B. Also, when the first rolling element 33 is positioned on the inclined portion 41, the movable member 11 is biased forward. Therefore, when the movable member 11 moves to its forward limit to load and unload the object to be processed M, it is possible to prevent the movable member 11 from unintentionally moving backward.

[0091] Furthermore, in this embodiment, the support plate portion 30 makes contact with both the floor surface, which is the installation surface 7 of the fixed member 12, and the interior floor surface 4B of the food processing machine 1, as the first rolling element 33 and the second rolling element 34 are guided down by the inclined portion 41. In this configuration, when the movable member 11 is moved forward, the movable member 11 makes contact with both the floor surface and the interior floor surface 4B, so the movable member 11 is stably supported. Therefore, high load-bearing capacity and stability can be achieved even when the trolley 5 or the worker moves on the support plate portion 30 when loading and unloading the object to be processed M.

[0092] Furthermore, in this embodiment, the fixed member 12 supports the movable member 11 from both sides in the left-right direction perpendicular to the front-rear direction. The movable member 11 has a pair of sliding parts 31 at both ends of the support plate 30 in the left-right direction, each equipped with a first rolling element 33 and a second rolling element 34. The operating part 32 extends upward from each sliding part 31 and has a handrail-like shape. In this configuration, since the operating part 32 is provided in a handrail-like shape on both sides of the support plate 30 which serves as a path, the movable member 11 can be moved easily with a simple structure. In addition, since the operating part 32 can be positioned at a high position away from the floor, workers can avoid gripping parts close to the floor, improving hygiene during loading and unloading operations. Furthermore, if a worker trips during loading or unloading operations, they can grab onto the operating part 32, so the loading / unloading guide board 10 (operating part 32) can also function as a safety device.

[0093] Furthermore, in this embodiment, the second rolling element 34 is positioned behind the first rolling element 33. In this configuration, when the movable member 11 moves forward, and a moment is generated that causes the movable member 11 to tilt forward around the first rolling element 33, the second rolling element 34 is supported on the lower surface of the guide plate 20, thereby preventing the movable member 11 from tilting. This prevents the front end of the movable member 11 from tilting downward when moving the movable member 11 forward, which could cause it to rub against the installation surface 7 during movement or fail to make contact with the interior floor surface 4B of the processing tank body 4 (resulting in the operator having to lift the front end of the movable member 11).

[0094] [Other embodiments] In this embodiment, an example is shown in which the operating section 32 is shaped like a handrail, but the operating section 32 may be, for example, columnar or wall-shaped. A handle or other grip may be provided on a part of the operating section 32.

[0095] In this embodiment, an example is shown in which the guide plate 20 is provided with an inclined portion 41, but the guide plate 20 does not need to have an inclined portion 41. For example, the guide plate 20 may be horizontal up to the front end PF. As mentioned above, the inclined portion 41 has the function of preventing the movable member 11 from unintentionally moving backward from its forward limit, but if the inclined portion 41 is not provided, a locking pin or the like may be provided to temporarily fix the movable member 11. The locking pin should be configured to engage with a part of the fixing member 12 when inserted into the insertion hole of the movable member 11, thereby preventing the movement of the movable member 11. Alternatively, the first rolling element 33 may be dropped forward from the front end PF of the guide plate 20 to bring the movable member 11 into contact with the interior floor surface 4B and prevent unintentional backward movement. In this case, when moving the movable member 11 backward, an external force should be applied to pull the movable member 11 slightly upward so that the first rolling element 33 rides up onto the guide plate 20.

[0096] In this embodiment, the support plate portion 30 is guided down by the inclined portion 41 and made contact with both the floor surface, which is the installation surface 7 of the fixing member 12, and the interior floor surface 4B of the food processing machine 1. However, the support plate portion 30 may only make contact with the interior floor surface 4B. In this case, the rear end of the support plate portion 30 may be supported by the fixing member 12 (such as the guide plate 20 or the fixing plate portion 24) while floating above the installation surface 7.

[0097] In this embodiment, an example is shown in which the fixed frame 21 has a pair of support parts 23 and a fixed plate part 24, but the fixed plate part 24 does not need to be provided. In this case, each of the pair of support parts 23 may be provided with a structure (such as a bolt insertion hole 24A) for attaching the support part 23 to the installation surface 7. In this case, the pair of support parts 23 can be positioned at a distance from each other according to the width dimension of the movable member 11 and then fixed separately to the installation surface 7.

[0098] In this embodiment, in the area of ​​the guide plate 20 excluding the inclined portion 41, the bottom surface 11A of the movable member 11 is set at a height higher than the bottom surface 12A of the fixed member 12. However, the bottom surface 11A of the movable member 11 may be set at the same height as the bottom surface 12A of the fixed member 12. In other words, the bottom surface 11A of the movable member 11 may be set to slide on the installation surface 7. The bottom surface 11A of the movable member 11 may be provided with a structure that reduces sliding resistance, such as a wheel.

[0099] In this embodiment, an example is shown in which a detachable blocking member 22 is provided on the fixed frame 21, but the blocking member 22 may be a non-detachable member. For example, if cleaning and disassembly are not required, the portion corresponding to the blocking member 22 may be integrally formed with the support portion 23.

[0100] In this embodiment, the first rolling element 33 and the second rolling element 34 are both positioned behind the center CP in the front-rear direction of the guide plate 20 at the position that represents the retraction limit of the movable member 11. However, the first rolling element 33 may also be positioned in front of the center CP in the front-rear direction of the guide plate 20. However, as the first rolling element 33 approaches the front end PF of the guide plate 20, the range of motion of the movable member 11 in the forward direction becomes relatively shorter. Therefore, in order to ensure a range of motion that allows the movable member 11 to pass over the drain pit 6 and reach the interior floor surface 4B, the total length of the fixed member 12 (guide plate 20) will be larger compared to the above embodiment.

[0101] In the embodiment, an example is shown in which a resistance-applying section 42 is provided, but the resistance-applying section 42 is not required. Also, in the embodiment, an example is shown in which the resistance-applying section 42 is made of an inclined surface, but the resistance-applying section 42 can have any shape as long as it can provide resistance to movement to the rolling element. For example, a projection, step, or recess may be formed on the surface of the guide plate 20 to serve as the resistance-applying section 42. The resistance-applying section 42 may also be provided on a part other than the guide plate 20.

[0102] In this embodiment, an example is shown in which the blocking member 22 is attached to the mounting portion 25 of the support portion 23 using a bolt 26 and a nut. However, the blocking member 22 may be attached by means other than the fastening member (bolt 26). For example, the mounting portion 25 of the support portion 23 may be a slot (mounting groove) into which a part of the blocking member 22 can be inserted from above. In this case, the blocking member 22 can be attached by inserting it into the slot from above, and the blocking member 22 can be removed by lifting it and pulling it out of the slot.
