Description

The present invention relates to a method and an apparatus for transferring sliced meat into a tray.

As a method for transferring sliced meat into a tray related to the present invention, for example, there is one disclosed in Patent Document 1 by the applicant. According to this method, a group of sliced meat for each pack amount, which is arranged in a scale with a part stacked in front of the folding line and conveyed to the end of the conveyor, falls from the end of the conveyor. It is placed on the tray waiting below the end of the conveyor. At this time, in order to fill the sliced meat group at once while maintaining the posture of the sliced meat group, when the sliced meat group reaches the end portion of the conveyor, the end portion of the conveyor is retracted relatively rapidly and the sliced meat group is dropped into the tray. It is a configuration to make.

According to the method of Patent Document 1, it may differ depending on the meat quality and the temperature of the meat, but if the thickness of the sliced meat exceeds 2 mm, it is arranged on the tray in an orderly manner, but if it is 2 mm or less, the sliced meat The beginning and end of the fall may be disturbed. In order to solve this problem, the applicant has proposed Japanese Patent Application No. 2018-172016. In this proposal, the sliced meat group is transferred to a transfer belt formed narrower than the width of the inner bottom of the tray, and then at least one of the transfer belt and the tray is tilted to tilt the tip of the transfer belt. Described is a method of transferring a group of sliced meat into a tray by retracting the transfer belt while maintaining a state in which the portion and the inner bottom of the tray are in close contact with each other.

In addition, it was made known in the above proposal.
A moving plate that is freely moved back and forth on the support frame is hung in the front-rear direction, and a part of the contact surface side with the sliced meat is fixed to the support frame. A transfer belt configured to move forward and backward as it moves forward and backward in a straight line,
Although the details are not described in the above proposal, for example, Patent Documents 2 to 4 specifically disclose the above.

According to the configuration of Patent Document 2, the transfer belt has a retractable support plate material (corresponding to the “reception plate” in the present invention) wound in a ring shape, and the support plate material is advanced. By transferring an object such as food on the transfer belt on the upper surface side of the support plate material and then retracting the support plate material, the object on the transfer belt is transferred to a desired position. The transfer belt is folded and wound around the front end and the rear end of the support plate material, and one end and the other end of the transfer belt are overlapped on the upper surface side of the support plate and transferred. It is sandwiched between a fixing member erected on the main body (corresponding to the "machine frame" in the present invention) and a holding plate, and is fixed to the transfer main body by a plurality of fixing screws.

In Patent Document 3, a fixed portion in which both ends of a belt (corresponding to the "transfer belt" in the present invention) around which a moving plate (corresponding to the "reception plate" in the present invention) is overlapped is defined as a concave portion and a convex portion. A configuration is described in which the portions are sandwiched and fixed from above and below with a fitting to be fitted, and then connected and fixed with a connecting tool such as a bolt. Further, in Patent Document 4, a sheet (corresponding to the "transfer belt" in the present invention) in which a slider (corresponding to the "reception plate" in the present invention) is rotated is sandwiched between two sandwiching materials, and both sandwiching materials are used. An example is described in which a method of fixing both ends with a clamp lever which is a stopper and an intermediate portion of both holding materials with a toggle clamp which is a stopper is used for a relatively large device.

Japanese Patent Application Laid-Open No. 2019-64808 JP-A-2007-222153 Japanese Unexamined Patent Publication No. 2008-184265 JP-A-2017-214108

When viewed from the side in the stacking direction, a group of sliced meats in which sliced meats are stacked in a scaly shape and are stacked in a row is apparent because the number of sliced meats overlapping at the beginning and end is small. It can be said that the thickness is thin. According to the method of Patent Document 1, the end portion of the conveyor is retracted relatively rapidly, and the thin head portion of the sliced meat group is vigorously peeled off from the conveyor, so that the sliced meat group falls. It starts. Immediately before being peeled off, the sliced meat group is sticky to the extent that it does not slip off even if the conveyor is tilted 30 degrees from the horizontal, and the part that has begun to be peeled off falls in the air without being guided by anything. It becomes. Therefore, when the elasticity of the folding line portion at the head of the sliced meat group is large, the sliced meat group is peeled off from the conveyor while maintaining its shape and falls, so that it is not easily disturbed. However, if the elasticity of the folding line at the beginning is small due to the thinness of the sliced meat, etc., the adhesive force will be lost and the peeling from the conveyor will vary, and the shape of the beginning will not be maintained and the meat will fall. Since it comes into contact with the tray, the head part may be disturbed.

According to the proposal of Japanese Patent Application No. 2018-172016 by the applicant, the head portion of the sliced meat group that has begun to be transferred from the transfer belt to the tray is substantially continuous even after being peeled off from the transfer belt. Contact the inner bottom. Therefore, even if the thickness of the sliced meat becomes thin, the entire sliced meat group including the beginning portion and the ending portion in the stacking direction of the sliced meat is not easily disturbed and can be transferred to the tray in an orderly manner. However, if the tip of the transfer belt urged by using an elastic force such as a spring is applied to the inner bottom of the tray to follow the tray, the tray made of foamed resin may be scratched or cracked. To avoid this, contact the tip of the transfer belt with a weak force that does not cause scratches or cracks on the inner bottom of the tray, or keep a slight gap about the thickness of the sliced meat and keep the inner bottom of the tray. It is necessary to make it follow the shape of. Although these can be realized by combining a servomotor, a sensor, and the like to perform pressing control and position control of the tip of the transfer belt, the mechanism becomes complicated. With such a mechanism, there are problems such as difficulty in maintenance of the machine and daily cleaning of the machine, and an increase in the cost of the machine.

Daily cleaning is essential to maintain cleanliness at places that come into contact with food and places close to it, such as transfer belts. However, as disclosed in Patent Documents 2 to 4, transfer belts are used. Once configured, the transfer belt must be removed to clean both the front and back sides of the transfer belt and the support plate material (or "moving plate" and "slider"). According to the configurations disclosed in Patent Documents 2 to 4, the transfer belt can be removed only by removing or loosening the screws. However, in the mounting of the transfer belt, in order to maintain the function of the transfer, the tension of the transfer belt and the position in the width direction need to be reproduced substantially the same, but these are reproduced in the mounting. There is no description on how to do this. In practice, it is particularly difficult to reproduce the tension, and with a relatively large transfer belt as in Patent Document 4, it is particularly difficult to reproduce the tension.

In stores such as grocery stores, products in which sliced meat groups stacked in a scale are arranged on a tray are arranged manually because the orderly arrangement of sliced meat groups also plays a part in the product value. Is common, but automation is required from the viewpoint of production efficiency and hygiene. An object of the present invention is that even if the sliced meat is thin, the sliced meat group is systematically transferred to the tray by a simple method and mechanism, and the tension of the transfer belt can be reproduced and the transfer belt can be attached / detached. It is easy to do.

The present invention is a transfer device for transferring a group of sliced meat in which a predetermined number of sliced meats are stacked in a scale shape and arranged in a row on a conveyor, and the sliced meat in the sliced meat group is transferred. The transfer belt is folded back from the upper surface of the receiving plate at the tip of the receiving plate and hung around the lower surface of the receiving plate on the receiving plate that can move in and out along the direction orthogonal to the stacking direction. The sliced meat group transferred from the transfer conveyor onto the transfer belt is placed in the tray so that the upper surface of the receiving plate is located below the upper surface of the transport conveyor on which the receiving plate is placed. It is a sliced meat transfer device characterized by being transferred to.

Further, it is preferable that the sliced meat in the sliced meat group is folded so as to have a folding line in a direction orthogonal to the stacking direction.

Further, it is preferable that the sliced meat group is conveyed by a conveyor along the stacking direction of the sliced meat in the sliced meat group.

Further, it is preferable that the sliced meat group has a predetermined transfer amount to a single tray.

Further, the transfer belt has an end on the upper surface side of the receiving plate as an upper holding member held by the machine frame of the transferring machine, and an end on the lower surface side of the receiving plate as a lower holding member of the transferring machine. It is preferable that a transfer device is provided, each of which is characterized by being detachable.

Further, an upper engaging portion that can be engaged with and disengaged from the upper holding member is formed at the end of the transfer belt on the upper surface side of the receiving plate, and the lower holding member is formed at the end of the transfer belt on the lower surface side of the receiving plate. It is preferable to provide a transfer device characterized in that a lower engaging portion that can be engaged with and disengaged is formed therein.

Further, the receiving plate and the lower holding member are connected via a timing belt, and one of the receiving plate and the lower holding member is driven, so that the receiving plate and the lower holding member speed up. It is preferable to provide a transfer device characterized by being driven in the same direction at a ratio of 1: 2.

Further, the engaging portions at both ends of the transfer belt are tubular spaces surrounded by the transfer belt, formed by fixing the folded tip portions to the transfer belt, and are the machine frames of the transfer equipment. The upper holding member held by the belt is a holding rod that is inserted into one engaging portion of the transfer belt and both ends are detachable at predetermined positions of the machine frame, and the lower holding member is at least one of them. From the end, it is preferable to provide a transfer device characterized in that the other engaging portion of the transfer belt is a holding plate material that can be engaged and disengaged.

In addition, the sliced meat group is conveyed in parallel by a conveyor, and the two transfer machines are arranged symmetrically with the tips of the receiving plates facing each other, and the receiving plates are moved away from each other in the outward direction. It is preferable that the sliced meat group is transferred from the transfer belt into the tray by moving toward.

The sliced meat transfer device and the transfer device of the present invention can be used in a sliced meat group by moving the backing plate along a direction orthogonal to the stacking direction of the sliced meat even if the sliced meat becomes thin. It can be transferred to the tray in an orderly manner with a simple mechanism by suppressing the disturbance of the part where the apparent thickness is thin, and in the transfer equipment, it is easy to reproduce the tension of the transfer belt and attach / detach the transfer belt. Will be done.

Examples of the sliced meat transfer device and the transfer device according to the present invention will be described with reference to FIGS. 1 to 17.

The sliced meat obtained by slicing the raw material pork loin with a meat slicer (not shown) is folded by a folding means (not shown) so as to have a folding line in a direction orthogonal to the conveying direction of the conveying conveyor 1. The folding wire is placed on the conveyor 1 with the folding wire directed to the downstream side of the conveyor 1. The thickness of the sliced meat to be folded is 1 mm to 2.5 mm, which occupies most of the market, and is used for shabu-shabu and the like.

After the folded and placed sliced meat m is sent downstream by the transport conveyor 1 by a predetermined amount of movement, the subsequent sliced meat m is placed in a scale shape so as to overlap a part of the preceding sliced meat m. To. When this is repeated up to the last sliced meat m of a predetermined number of sheets to be placed on one tray 3, the sliced meat group M is placed on the conveyor 1 as shown in FIG.

In the meat slicer and the folding means, two rows of sliced meat m arranged in parallel are placed on the conveyor 1, but one row of sliced meat m can also be placed. A conveyor 1 is sent between the two-row or one-row sliced meat group M and the subsequent sliced meat group M so that the division becomes clear, and an interval is provided, and this is repeated to provide the sliced meat group. M is conveyed to the end of the transfer conveyor 1. In this embodiment, a two-row sliced meat group M will be used for explanation.

The folding means can change the folding position of the sliced meat. By setting the folding position to be outside the sliced meat, it is possible to obtain a scale-shaped sliced meat group M1 by the unfolded sliced meat m1, but the sliced meat m1 is often folded. Since it is thicker than the sliced meat m and has a large elasticity, it is not easily disturbed at the time of transfer. Therefore, in this embodiment, the sliced meat group M made of the folded sliced meat m will be described. As a reference, the unfolded sliced meat m1 is often 3 mm or more thick and is used for shogayakiya and pork cutlet.

The conveyor 1 is gently inclined so that the end portion descends toward the downstream side, and as shown by a virtual line in FIG. 4, the end portion of the conveyor 1 is terminated without changing the absolute position of the article placed on the upper surface of the conveyor. It is a shuttle conveyor (the drive part and the like are not shown) in which the part advances and retreats in the horizontal direction by a predetermined distance. The inclination of the conveyor 1 in FIG. 4 is about 21 degrees.

Below the end of the conveyor 1, transfer tools 10 and 10 are provided symmetrically with the leading ends of the receiving plates 21 facing each other in the advancing direction.

Regarding the transfer device 10, as shown in FIG. 11, the left-right direction in which the receiving plate 21 advances to the position shown in FIG. 11 and moves out to the position shown in FIG. 14 is the exit / exit direction, and the upper side in FIG. 11 is the upstream side. The lower side will be described as the downstream side. The transfer machine 10 is a lower part that linearly moves the machine frame 11, the receiving plate 21, the transfer belt 31 hung around the receiving plate 21, and the lower end of the receiving plate 21 of the transfer belt 31. A side holding member 41 and an interlocking means 51 for associating the receiving plate 21 and the lower holding member 41 with each other and moving them back and forth are provided.

As shown in FIG. 11, the machine frame 11 is assembled with the side plates 12 and 12, the downstream side plate 13 erected on the side plates 12 and 12, and erected upstream from the substantially central portion of the downstream side plate 13. The member 14, the upstream plate 15 extending in parallel with the downstream plate 13 on the upstream side of the assembling member 14, and the cylindrical portion erected in parallel with the assembling member 14 and around which the transfer belt 31 is wound. The upper holding member locking portion 16 is provided. The assembling member 14 is a plate material having a U-shaped cross section, and is provided with an assembling bolt or the like so that it can be detachably assembled to the machine frame of the conveyor 1.

The receiving plate 21 is a thin stainless steel plate, and the receiving plate sliders 23 and 23 through which the receiving plate guide rods 22 erected on the side plates 12 and 12 are inserted are fixed to the downstream side, and the receiving plate rails are fixed to the upstream side. It is slidably supported by 24 and is movable in the exit / exit direction. The tip end portion of the receiving plate 21 in the advancing direction is a rounded end portion that is bent so as to overlap the lower surface side, and is considered so that it can be slidably contacted with the transfer belt 31. Further, the rear end portion of the receiving plate 21 in the advancing direction is bent downward by approximately 45 degrees so that the edge portion of the rear end of the receiving plate 21 does not hit the transfer belt 31 on the upper surface side of the receiving plate 21. ..

The transfer belt 31 is folded back from the upper surface of the receiving plate 21 at the tip of the receiving plate 21 and hung around the lower surface of the receiving plate 21.
Further, as shown in FIG. 16, the transfer belt 31 is formed so that the tip portions of both ends of the transfer belt 31 are folded back to form a tubular space surrounded by the transfer belt 31. It is glued to. The tubular spaces formed at both ends are engaged with the upper holding member 34 on the upper surface side of the receiving plate 21 and the upper engaging portion 32 which can be engaged with and disengaged from the upper holding member 34, and the other is engaged with the lower holding member 41 on the lower surface side of the receiving plate 21. It is a detachable lower engaging portion 33.

The lower holding member 41 is a thin stainless steel plate that is movable in the retracting direction while maintaining a gap of about 3 mm from the lower surface side of the receiving plate 21, and is erected on the side plates 12 and 12 on the downstream side. The lower holding member sliders 43, 43 through which the lower holding member guide rod 42 is inserted are fixed, and the upstream side is slidably supported by the lower holding member rail 44. The lower holding member rail 44 is rotatably supported by the upstream side plate members 15 by the rail fulcrum pins 18 and 18, and is fixed to the supporting position of the lower holding member 41 by the rail portion fixing pins 19 and 19. It can be released freely. The rail portion fixing pins 19 and 19 in this embodiment are index plungers, and the lower holding member rail 44 can be easily fixed and released to the support position simply by operating the knob of the index plunger.

When the lower holding member rail 44 is released from the support position, the lower holding member 41 can be inserted into the lower engaging portion 33 from the upstream side thereof. The lower holding member 41 is formed with notches that regulate the outside of both ends of the tubular portion of the lower engaging portion 33 by approximately 1 mm and hold the lower engaging portion 33 so that it is difficult to pull out. The lower engaging portion 33 is held in a substantially fixed position by hooking it on the notch while slightly deforming both ends, and it is easy to attach / detach.

The upper holding member 34 is a round bar that can be inserted into the upper engaging portion 32 and has a step on a part thereof, and the outer side of both ends of the tubular portion of the upper engaging portion 32 has a large diameter and is transferred. When the belt 31 is attached, both ends of the tubular portion are guided by a step in diameter and are held at a substantially fixed position. The outer ends of the large diameter are made smaller in diameter, and the upper holding member 34 is positioned within a range having a gap of approximately 0.5 mm at both ends with respect to the upper holding member locking portion 16, and the upper holding member fixing pin 17 , 17 fixed. The upper holding member fixing pins 17 and 17 in this embodiment are index plungers, and the upper holding member 34 can be easily attached to and detached from the upper holding member locking portion 16 and transferred by simply operating the knob of the index plunger. The position of the belt 31 in the width direction is reproduced as necessary and sufficient.

When attaching the transfer belt 31, after the lower engaging portion 33 of the transfer belt 31 is attached to the lower holding member 41, the lower holding member rail 44 is fixed to the support position and the lower holding member After the 41 is supported, the transfer belt 31 is folded back from the lower surface of the receiving plate 21 at the tip of the receiving plate 21 and hung around the upper surface of the receiving plate 21. Next, after the upper holding member 34 is inserted into the upper engaging portion 32, the upper holding member 34 is fixed so that the transfer belt 31 is wound around the cylindrical portion of the upper holding member locking portion 16. According to this procedure, the positions of both ends of the transfer belt 31 are substantially the same as those before the removal, and the tension of the transfer belt 31 is reproduced substantially the same as before the removal. When removing the transfer belt 31, the above procedure may be reversed.

Next, the interlocking means 51 will be described. The timing belt 53 hung on the timing pulleys 52, 52 rotatably supported by the receiving plate sliders 23, 23 is a timing belt fixing body in which a part thereof is fixed to a substantially central portion of the receiving plate guide rod 22. It is fixed at 54. The timing belt connecting body 55 into which the lower holding member guide rod 42 is inserted is rotatably sandwiched between the lower holding member sliders 43 and 43, and the timing belt 53 is rotatably sandwiched from the timing belt fixing body 54 in both directions. The timing belt 53 is fixed at a position having substantially the same length in.

According to the above configuration, as shown in FIG. 17, when the receiving plate 21 is moved by a distance S with respect to the machine frame 11 by an air cylinder (not shown), the lower side is moved via the timing belt 53. Since the holding member 41 is moved in the same direction with respect to the receiving plate 21 by the same distance S, the lower holding member 41 is moved by a distance 2S with respect to the machine frame 11. That is, since the lower holding member 41 is moved in the same direction at twice the speed of the receiving plate 21, the transfer belt 31 hung around the receiving plate 21 by the interlocking means 51 does not sag. Always in sliding contact with the tip.

As described above, the transfer machine 10 and the transfer belt 31 can be easily attached to and detached from each other during cleaning after the work is completed, and it is not necessary to adjust the tension when attaching the transfer belt 31 after cleaning. .. It should be noted that the transfer belt 31 may need to be adjusted in tension due to changes over time due to use and replacement due to deterioration or breakage. At this time, by loosening the bolt to which the upper holding member locking portion 16 is fixed, rotating it in the circumferential direction in FIG. 12 and tightening the bolt, the winding angle of the transfer belt 31 to the upper holding member locking portion 16 is set. Changes and can be adjusted to the appropriate tension.

A tray transfer device 2 for transferring the tray 3 along a direction orthogonal to the transfer direction of the transfer conveyor 1 is provided below the receiving plate 21 in the transfer device 10 configured as described above. The tray 3 is transferred to a suitable position by the tray transfer device 2 and lifted so that the sliced meat group M is transferred to a substantially central portion in the tray transfer direction. The tray transfer device 2 has a height that is not affected by the transfer operation of the tray transfer device 2 after transferring one of the corresponding trays 3 and 3 to a suitable position in the sliced meat groups M and M in the two rows. Lift it up. Then, by transferring the other to a suitable position and lifting it up, both the trays 3 and 3 corresponding to the sliced meat groups M and M in the two rows are transferred to a suitable position.

The transfer method of the transfer device configured in this manner in this embodiment will be described with reference to the drawings. FIG. 1 shows a state in which the end portion of the transport conveyor 1 is retracted as shown in FIG. 4, and the sliced meat group M is placed on the transfer belt 31 on the upper surface of the receiving plate 21 from the transport conveyor 1. The gap between the lower surface of the terminal portion of the transport conveyor 1 and the transfer belt 31 on the upper surface of the receiving plate 21 is approximately 2 mm, and after the head portion of the sliced meat group M that has begun to leave the terminal portion of the transport conveyor 1. Is sequentially transferred while contacting the transfer belt 31 on the upper surface of the receiving plate 21 substantially continuously, so that the transfer belt 31 is neatly placed on the transfer belt 31 while suppressing disturbance. At this time, the trays 3 and 3 are transferred to a suitable position below the receiving plates 21 and 21 by the tray transfer device 2 and lifted.

Next, the receiving plate 21 is retracted along the direction orthogonal to the stacking direction of the sliced meat m. As described above, since the transfer belt 31 is always in sliding contact with the tip of the receiving plate 21 without sagging, the transfer belt 31 on the upper surface of the receiving plate 21 does not change its position relative to the lower surface of the sliced meat group M. As they are peeled off, the sliced meat group M begins to fall from the lateral portion in the stacking direction as shown in FIGS. 5 and 6.

Here, in FIG. 10 when the sliced meat group M is viewed from the side in the stacking direction, the number of overlapping sliced meats is the beginning portion (left end in FIG. 10) and the end portion (FIG. 10) as compared with the substantially four pieces of the central portion. At the right end of 10), the apparent thickness is as thin as two. More specifically, the apparent thickness of the central portion of the sliced meat group M is about 3 to 6 sliced meats if it is small depending on the degree of overlap of the sliced meats m, but it is about 6 sheets if it is large, but the leading portion with a folding line. The apparent thickness is about 2 slices of meat, and the apparent thickness of the tail portion is 2 or 1 slice of meat depending on the folding position.

As a reference, in the sliced meat group M1 made of unfolded sliced meat m1, the apparent thickness of the central portion is about 2 to 4 slices of meat, and the thickness of the beginning portion and the ending portion is 1 sliced meat. It is for one sheet.

According to the method of Patent Document 1, the leading folding line portion of the sliced meat group M in the stacking direction is peeled off from the conveyor at substantially the same time. As the thickness of the sliced meat decreases, the elasticity of the folding line portion decreases, so that the peeling method of the folding line portion that adheres to the conveyor to some extent varies. In addition, it is difficult to keep the folding line part in a straight shape due to its small elasticity even when the leading part is falling or comes into contact with the tray. From these facts, it is difficult to orderly transfer the leading portion of the sliced meat group M of thin sliced meat to the tray.

In this embodiment, since the sliced meat group M starts to fall from the side portion, the head portion and the tail portion in the stacking direction are in the direction orthogonal to the stacking direction (direction along the folding line) from the transfer belt 31. It falls while being peeled off in sequence. Therefore, even if the thickness of the sliced meat is reduced, the particularly conspicuous leading folding line portion tends to maintain a linear shape, and the entire sliced meat group M is transferred to the tray in an orderly manner.

In this embodiment, the end portion of the transfer conveyor 1 which is a shuttle conveyor is retracted so that the sliced meat group M is placed on the transfer belt 31, but for example, the transfer conveyor always has the end portion at a fixed position. The entire transfer machine 10 with the receiving plate 21 advanced is transferred to the transfer conveyor so that the sliced meat group M is delivered onto the transfer belt 31 in relation to the feed at the end of the transfer conveyor. It may be moved along the direction.

Further, in this embodiment, the tray transfer device 2 transfers the tray 3 to a suitable position, but the tray transfer device always transfers the tray 3 to the same position and moves the transfer device 10 to a suitable position with respect to the tray 3. You may.

In the present invention, the device for orderly transferring the sliced meat group from the transfer belt 31 to the tray 3 is realized by a simple mechanism by combining linear movements as in the above-described embodiment, and thus is a machine. It is easy to maintain and clean the machine every day, and the cost of the machine can be reduced.

The transfer device 10 in the present invention is particularly useful for transferring a group of sliced meats stacked in a scale shape, which is soft to be manually transferred and whose posture and shape are easily disturbed as in the present embodiment. However, the items to be transferred are not limited. In addition, the material and shape of each part can be changed as appropriate if they meet the functional requirements.

The present invention relates to a method and an apparatus for transferring sliced meat into a tray.

As a method for transferring sliced meat into a tray related to the present invention, for example, there is one disclosed in Patent Document 1 by the applicant. According to this method, a group of sliced meat for each pack amount, which is arranged in a scale with a part stacked in front of the folding line and conveyed to the end of the conveyor, falls from the end of the conveyor. It is placed on the tray waiting below the end of the conveyor. At this time, in order to fill the sliced meat group at once while maintaining the posture of the sliced meat group, when the sliced meat group reaches the end portion of the conveyor, the end portion of the conveyor is retracted relatively rapidly and the sliced meat group is dropped into the tray. It is a configuration to make.

According to the method of Patent Document 1, it may differ depending on the meat quality and the temperature of the meat, but if the thickness of the sliced meat exceeds 2 mm, it is arranged on the tray in an orderly manner, but if it is 2 mm or less, the sliced meat The beginning and end of the fall may be disturbed. In order to solve this problem, the applicant has proposed Japanese Patent Application No. 2018-172016. In this proposal, the sliced meat group is transferred to a transfer belt formed narrower than the width of the inner bottom of the tray, and then at least one of the transfer belt and the tray is tilted to tilt the tip of the transfer belt. Described is a method of transferring a group of sliced meat into a tray by retracting the transfer belt while maintaining a state in which the portion and the inner bottom of the tray are in close contact with each other.

In addition, it was made known in the above proposal.
Together are Kai over in the longitudinal direction of the movably supported moving plate to the support frame, a portion of the contact surface of the slice meat have been fixed to the support frame, the moving plate by moving means is relative to the support frame A transfer belt that is configured to move forward and backward as it moves forward and backward in a straight line.
Although the details are not described in the above proposal, for example, Patent Documents 2 to 4 specifically disclose the above.

According to the configuration of Patent Document 2, the transfer belt has a retractable support plate material (corresponding to the “reception plate” in the present invention) wound in a ring shape, and the support plate material is advanced. By transferring an object such as food on the transfer belt on the upper surface side of the support plate material and then retracting the support plate material, the object on the transfer belt is transferred to a desired position. The transfer belt is folded and wound around the front end and the rear end of the support plate material, and one end and the other end of the transfer belt are overlapped on the upper surface side of the support plate and transferred. It is sandwiched between a fixing member erected on the main body (corresponding to the "machine frame" in the present invention) and a holding plate, and is fixed to the transfer main body by a plurality of fixing screws.

In Patent Document 3, a fixed portion in which both ends of a belt (corresponding to the "transfer belt" in the present invention) around which a moving plate (corresponding to the "reception plate" in the present invention) is overlapped is defined as a concave portion and a convex portion. A configuration is described in which the portions are sandwiched and fixed from above and below with a fitting to be fitted, and then connected and fixed with a connecting tool such as a bolt. Further, in Patent Document 4, a sheet (corresponding to the "transfer belt" in the present invention) in which a slider (corresponding to the "reception plate" in the present invention) is rotated is sandwiched between two sandwiching materials, and both sandwiching materials are used. An example is described in which a method of fixing both ends with a clamp lever which is a stopper and an intermediate portion of both holding materials with a toggle clamp which is a stopper is used for a relatively large device.

JP-A-2019-64808 JP-A-2007-222153 Japanese Unexamined Patent Publication No. 2008-184265 JP-A-2017-214108

When viewed from the side in the stacking direction, a group of sliced meats in which sliced meats are stacked in a scaly shape and are stacked in a row is apparent because the number of sliced meats overlapping at the beginning and end is small. It can be said that the thickness is thin. According to the method of Patent Document 1, the end portion of the conveyor is retracted relatively rapidly, and the thin head portion of the sliced meat group is vigorously peeled off from the conveyor, so that the sliced meat group falls. It starts. Immediately before being peeled off, the sliced meat group is sticky to the extent that it does not slip off even if the conveyor is tilted 30 degrees from the horizontal, and the part that has begun to be peeled off falls in the air without being guided by anything. It becomes. Therefore, when the elasticity of the folding line portion at the head of the sliced meat group is large, the sliced meat group is peeled off from the conveyor while maintaining its shape and falls, so that it is not easily disturbed. However, if the elasticity of the folding line at the beginning is small due to the thinness of the sliced meat, etc., the adhesive force will be lost and the peeling from the conveyor will vary, and the shape of the beginning will not be maintained and the meat will fall. Since it comes into contact with the tray, the head part may be disturbed.

According to the proposal of Japanese Patent Application No. 2018-172016 by the applicant, the head portion of the sliced meat group that has begun to be transferred from the transfer belt to the tray is substantially continuous even after being peeled off from the transfer belt. Contact the inner bottom. Therefore, even if the thickness of the sliced meat becomes thin, the entire sliced meat group including the beginning portion and the ending portion in the stacking direction of the sliced meat is not easily disturbed and can be transferred to the tray in an orderly manner. However, if the tip of the transfer belt urged by using an elastic force such as a spring is applied to the inner bottom of the tray to follow the tray, the tray made of foamed resin may be scratched or cracked. To avoid this, contact the tip of the transfer belt with a weak force that does not cause scratches or cracks on the inner bottom of the tray, or keep a slight gap about the thickness of the sliced meat and keep the inner bottom of the tray. It is necessary to make it follow the shape of. Although these can be realized by combining a servomotor, a sensor, and the like to perform pressing control and position control of the tip of the transfer belt, the mechanism becomes complicated. With such a mechanism, there are problems such as difficulty in maintenance of the machine and daily cleaning of the machine, and an increase in the cost of the machine.

Daily cleaning is essential to maintain cleanliness at places that come into contact with food and places close to it, such as transfer belts. However, as disclosed in Patent Documents 2 to 4, transfer belts are used. Once configured, the transfer belt must be removed to clean both the front and back sides of the transfer belt and the support plate material (or "moving plate" and "slider"). According to the configurations disclosed in Patent Documents 2 to 4, the transfer belt can be removed only by removing or loosening the screws. However, in the mounting of the transfer belt, in order to maintain the function of the transfer, the tension of the transfer belt and the position in the width direction need to be reproduced substantially the same, but these are reproduced in the mounting. There is no description on how to do this. In practice, it is particularly difficult to reproduce the tension, and with a relatively large transfer belt as in Patent Document 4, it is particularly difficult to reproduce the tension.

In stores such as grocery stores, products in which sliced meat groups stacked in a scale are arranged on a tray are arranged manually because the orderly arrangement of sliced meat groups also plays a part in the product value. Is common, but automation is required from the viewpoint of production efficiency and hygiene. An object of the present invention is that even if the sliced meat is thin, the sliced meat group is systematically transferred to the tray by a simple method and mechanism, and the tension of the transfer belt can be reproduced and the transfer belt can be attached / detached. It is easy to do.

The present invention is a transfer device for transferring a group of sliced meat in which a predetermined number of sliced meats are stacked in a scale shape and arranged in a row on a conveyor, and the sliced meat in the sliced meat group is transferred. along a direction perpendicular to the stacked direction projecting and retracting a movable receiving plate, transferred Kigu was rotating over the receiving plate lower surface returns folded in the receiving plate tip the transfer belt from the receiving plate upper surface, sliced meat The top surface of the receiving plate is arranged so as to be lower than the upper surface of the transport conveyor on which the group is placed, and the sliced meat group transferred from the transport conveyor onto the transfer belt is removed from the tray. It is a sliced meat transfer device characterized by being transferred inward.

It is preferable that a transfer device is provided, each of which is characterized by being detachable.

Further, an upper engaging portion that can be engaged with and disengaged from the upper holding member is formed at the end of the transfer belt on the upper surface side of the receiving plate, and the lower holding member is formed at the end of the transfer belt on the lower surface side of the receiving plate. It is preferable to provide a transfer device characterized in that a lower engaging portion that can be engaged with and disengaged is formed therein.

Further, the receiving plate and the lower holding member are connected via a timing belt, and one of the receiving plate and the lower holding member is driven, so that the receiving plate and the lower holding member speed up. It is preferable to provide a transfer device characterized by being driven in the same direction at a ratio of 1: 2.

Further, the engaging portions at both ends of the transfer belt are tubular spaces surrounded by the transfer belt, formed by fixing the folded tip portions to the transfer belt, and are the machine frames of the transfer equipment. The upper holding member held by the belt is a holding rod that is inserted into one engaging portion of the transfer belt and both ends are detachable at predetermined positions of the machine frame, and the lower holding member is at least one of them. From the end, it is preferable to provide a transfer device characterized in that the other engaging portion of the transfer belt is a holding plate material that can be engaged and disengaged.

In addition, the sliced meat group is conveyed in parallel by a conveyor, and the two transfer machines are arranged symmetrically with the tips of the receiving plates facing each other, and the receiving plates are moved away from each other in the outward direction. It is preferable that the sliced meat group is transferred from the transfer belt into the tray by moving toward.

The sliced meat transfer device and the transfer device of the present invention can be used in a sliced meat group by moving the backing plate along a direction orthogonal to the stacking direction of the sliced meat even if the sliced meat becomes thin. It can be transferred to the tray in an orderly manner with a simple mechanism by suppressing the disturbance of the part where the apparent thickness is thin, and in the transfer equipment, it is easy to reproduce the tension of the transfer belt and attach / detach the transfer belt. Will be done.

Examples of the sliced meat transfer device and the transfer device according to the present invention will be described with reference to FIGS. 1 to 17.

The sliced meat obtained by slicing the raw material pork loin with a meat slicer (not shown) is folded by a folding means (not shown) so as to have a folding line in a direction orthogonal to the conveying direction of the conveying conveyor 1. The folding wire is placed on the conveyor 1 with the folding wire directed to the downstream side of the conveyor 1. The thickness of the sliced meat to be folded is 1 mm to 2.5 mm, which occupies most of the market, and is used for shabu-shabu and the like.

After the folded and placed sliced meat m is sent downstream by the transport conveyor 1 by a predetermined amount of movement, the subsequent sliced meat m is placed in a scale shape so as to overlap a part of the preceding sliced meat m. To. When this is repeated up to the last sliced meat m of a predetermined number of sheets to be placed on one tray 3, the sliced meat group M is placed on the conveyor 1 as shown in FIG.

In the meat slicer and the folding means, two rows of sliced meat m arranged in parallel are placed on the conveyor 1, but one row of sliced meat m can also be placed. A conveyor 1 is sent between the two-row or one-row sliced meat group M and the subsequent sliced meat group M so that the division becomes clear, and an interval is provided, and this is repeated to provide the sliced meat group. M is conveyed to the end of the transfer conveyor 1. In this embodiment, a two-row sliced meat group M will be used for explanation.

The folding means can change the folding position of the sliced meat. By setting the folding position to be outside the sliced meat, it is possible to obtain a scale-shaped sliced meat group M1 by the unfolded sliced meat m1, but the sliced meat m1 is often folded. Since it is thicker than the sliced meat m and has a large elasticity, it is not easily disturbed at the time of transfer. Therefore, in this embodiment, the sliced meat group M made of the folded sliced meat m will be described. As a reference, the unfolded sliced meat m1 is often 3 mm or more thick and is used for shogayakiya and pork cutlet.

The conveyor 1 is gently inclined so that the end portion descends toward the downstream side, and as shown by a virtual line in FIG. 4, the end portion of the conveyor 1 is terminated without changing the absolute position of the article placed on the upper surface of the conveyor. It is a shuttle conveyor (the drive part and the like are not shown) in which the part advances and retreats in the horizontal direction by a predetermined distance. The inclination of the conveyor 1 in FIG. 4 is about 21 degrees.

Below the end of the conveyor 1, transfer tools 10 and 10 are provided symmetrically with the leading ends of the receiving plates 21 facing each other in the advancing direction.

Regarding the transfer device 10, as shown in FIG. 11, the left-right direction in which the receiving plate 21 advances to the position shown in FIG. 11 and moves out to the position shown in FIG. 14 is the exit / exit direction, and the upper side in FIG. 11 is the upstream side. The lower side will be described as the downstream side. The transfer machine 10 is a lower part that linearly moves the machine frame 11, the receiving plate 21, the transfer belt 31 hung around the receiving plate 21, and the lower end of the receiving plate 21 of the transfer belt 31. A side holding member 41 and an interlocking means 51 for associating the receiving plate 21 and the lower holding member 41 with each other and moving them back and forth are provided.

The upper holding member locking portion 16 is provided. The assembling member 14 is a plate material having a U-shaped cross section, and is provided with an assembling bolt or the like so that it can be detachably assembled to the machine frame of the conveyor 1.

The receiving plate 21 is a thin stainless steel plate, and the receiving plate sliders 23 and 23 through which the receiving plate guide rods 22 erected on the side plates 12 and 12 are inserted are fixed to the downstream side, and the receiving plate rails are fixed to the upstream side. It is slidably supported by 24 and is movable in the exit / exit direction. The tip end portion of the receiving plate 21 in the advancing direction is a rounded end portion that is bent so as to overlap the lower surface side, and is considered so that it can be slidably contacted with the transfer belt 31. Further, the rear end portion of the receiving plate 21 in the advancing direction is bent downward by approximately 45 degrees so that the edge portion of the rear end of the receiving plate 21 does not hit the transfer belt 31 on the upper surface side of the receiving plate 21. ..

The transfer belt 31 is folded back from the upper surface of the receiving plate 21 at the tip of the receiving plate 21 and hung around the lower surface of the receiving plate 21.
Further, as shown in FIG. 16, the transfer belt 31 is formed so that the tip portions of both ends of the transfer belt 31 are folded back to form a tubular space surrounded by the transfer belt 31. It is glued to. The tubular spaces formed at both ends are engaged with the upper holding member 34 on the upper surface side of the receiving plate 21 and the upper engaging portion 32 which can be engaged with and disengaged from the upper holding member 34, and the other is engaged with the lower holding member 41 on the lower surface side of the receiving plate 21. It is a detachable lower engaging portion 33.

The lower holding member 41 is a thin stainless steel plate that is movable in the retracting direction while maintaining a gap of about 3 mm from the lower surface side of the receiving plate 21, and is erected on the side plates 12 and 12 on the downstream side. The lower holding member sliders 43, 43 through which the lower holding member guide rod 42 is inserted are fixed, and the upstream side is slidably supported by the lower holding member rail 44. The lower holding member rail 44 is rotatably supported by the upstream side plate members 15 by the rail fulcrum pins 18 and 18, and is fixed to the supporting position of the lower holding member 41 by the rail portion fixing pins 19 and 19. It can be released freely. The rail portion fixing pins 19 and 19 in this embodiment are index plungers, and the lower holding member rail 44 can be easily fixed and released to the support position simply by operating the knob of the index plunger.

When the lower holding member rail 44 is released from the support position, the lower holding member 41 can be inserted into the lower engaging portion 33 from the upstream side thereof. The lower holding member 41 is formed with notches that regulate the outside of both ends of the tubular portion of the lower engaging portion 33 by approximately 1 mm and hold the lower engaging portion 33 so that it is difficult to pull out. The lower engaging portion 33 is held in a substantially fixed position by hooking it on the notch while slightly deforming both ends, and it is easy to attach / detach.

The upper holding member 34 is a round bar that can be inserted into the upper engaging portion 32 and has a step on a part thereof, and the outer side of both ends of the tubular portion of the upper engaging portion 32 has a large diameter and is transferred. When the belt 31 is attached, both ends of the tubular portion are guided by a step in diameter and are held at a substantially fixed position. The outer ends of the large diameter are made smaller in diameter, and the upper holding member 34 is positioned within a range having a gap of approximately 0.5 mm at both ends with respect to the upper holding member locking portion 16, and the upper holding member fixing pin 17 , 17 fixed. The upper holding member fixing pins 17 and 17 in this embodiment are index plungers, and the upper holding member 34 can be easily attached to and detached from the upper holding member locking portion 16 and transferred by simply operating the knob of the index plunger. The position of the belt 31 in the width direction is reproduced as necessary and sufficient.

When attaching the transfer belt 31, after the lower engaging portion 33 of the transfer belt 31 is attached to the lower holding member 41, the lower holding member rail 44 is fixed to the support position and the lower holding member After the 41 is supported, the transfer belt 31 is folded back from the lower surface of the receiving plate 21 at the tip of the receiving plate 21 and hung around the upper surface of the receiving plate 21. Next, after the upper holding member 34 is inserted into the upper engaging portion 32, the upper holding member 34 is fixed so that the transfer belt 31 is wound around the cylindrical portion of the upper holding member locking portion 16. According to this procedure, the positions of both ends of the transfer belt 31 are substantially the same as those before the removal, and the tension of the transfer belt 31 is reproduced substantially the same as before the removal. When removing the transfer belt 31, the above procedure may be reversed.

Next, the interlocking means 51 will be described. The timing belt 53 hung on the timing pulleys 52, 52 rotatably supported by the receiving plate sliders 23, 23 is a timing belt fixing body in which a part thereof is fixed to a substantially central portion of the receiving plate guide rod 22. It is fixed at 54. The timing belt connecting body 55 into which the lower holding member guide rod 42 is inserted is rotatably sandwiched between the lower holding member sliders 43 and 43, and the timing belt 53 is rotatably sandwiched from the timing belt fixing body 54 in both directions. The timing belt 53 is fixed at a position having substantially the same length in.

According to the above configuration, as shown in FIG. 17, when the receiving plate 21 is moved by a distance S with respect to the machine frame 11 by an air cylinder (not shown), the lower side is moved via the timing belt 53. Since the holding member 41 is moved in the same direction with respect to the receiving plate 21 by the same distance S, the lower holding member 41 is moved by a distance 2S with respect to the machine frame 11. That is, since the lower holding member 41 is moved in the same direction at twice the speed of the receiving plate 21, the transfer belt 31 hung around the receiving plate 21 by the interlocking means 51 does not sag. Always in sliding contact with the tip.

As described above, the transfer machine 10 and the transfer belt 31 can be easily attached to and detached from each other during cleaning after the work is completed, and it is not necessary to adjust the tension when attaching the transfer belt 31 after cleaning. .. It should be noted that the transfer belt 31 may need to be adjusted in tension due to changes over time due to use and replacement due to deterioration or breakage. At this time, by loosening the bolt to which the upper holding member locking portion 16 is fixed, rotating it in the circumferential direction in FIG. 12 and tightening the bolt, the winding angle of the transfer belt 31 to the upper holding member locking portion 16 is set. Changes and can be adjusted to the appropriate tension.

A tray transfer device 2 for transferring the tray 3 along a direction orthogonal to the transfer direction of the transfer conveyor 1 is provided below the receiving plate 21 in the transfer device 10 configured as described above. The tray 3 is transferred to a suitable position by the tray transfer device 2 and lifted so that the sliced meat group M is transferred to a substantially central portion in the tray transfer direction. The tray transfer device 2 has a height that is not affected by the transfer operation of the tray transfer device 2 after transferring one of the corresponding trays 3 and 3 to a suitable position in the sliced meat groups M and M in the two rows. Lift it up. Then, by transferring the other to a suitable position and lifting it up, both the trays 3 and 3 corresponding to the sliced meat groups M and M in the two rows are transferred to a suitable position.

The transfer method of the transfer device configured in this manner in this embodiment will be described with reference to the drawings. FIG. 1 shows a state in which the end portion of the transport conveyor 1 is retracted as shown in FIG. 4, and the sliced meat group M is placed on the transfer belt 31 on the upper surface of the receiving plate 21 from the transport conveyor 1. The gap between the lower surface of the terminal portion of the transport conveyor 1 and the transfer belt 31 on the upper surface of the receiving plate 21 is approximately 2 mm, and after the head portion of the sliced meat group M that has begun to leave the terminal portion of the transport conveyor 1. Is sequentially transferred while contacting the transfer belt 31 on the upper surface of the receiving plate 21 substantially continuously, so that the transfer belt 31 is neatly placed on the transfer belt 31 while suppressing disturbance. At this time, the trays 3 and 3 are transferred to a suitable position below the receiving plates 21 and 21 by the tray transfer device 2 and lifted.

Next, the receiving plate 21 is retracted along the direction orthogonal to the stacking direction of the sliced meat m. As described above, since the transfer belt 31 is always in sliding contact with the tip of the receiving plate 21 without sagging, the transfer belt 31 on the upper surface of the receiving plate 21 does not change its position relative to the lower surface of the sliced meat group M. As they are peeled off, the sliced meat group M begins to fall from the lateral portion in the stacking direction as shown in FIGS. 5 and 6.

Here, in FIG. 10 when the sliced meat group M is viewed from the side in the stacking direction, the number of overlapping sliced meats is the beginning portion (left end in FIG. 10) and the end portion (FIG. 10) as compared with the substantially four pieces of the central portion. At the right end of 10), the apparent thickness is as thin as two. More specifically, the apparent thickness of the central portion of the sliced meat group M is about 3 to 6 sliced meats if it is small depending on the degree of overlap of the sliced meats m, but it is about 6 sheets if it is large, but the leading portion with a folding line. The apparent thickness is about 2 slices of meat, and the apparent thickness of the tail portion is 2 or 1 slice of meat depending on the folding position.

As a reference, in the sliced meat group M1 made of unfolded sliced meat m1, the apparent thickness of the central portion is about 2 to 4 slices of meat, and the thickness of the beginning portion and the ending portion is 1 sliced meat. It is for one sheet.

According to the method of Patent Document 1, the leading folding line portion of the sliced meat group M in the stacking direction is peeled off from the conveyor at substantially the same time. As the thickness of the sliced meat decreases, the elasticity of the folding line portion decreases, so that the peeling method of the folding line portion that adheres to the conveyor to some extent varies. In addition, it is difficult to keep the folding line part in a straight shape due to its small elasticity even when the leading part is falling or comes into contact with the tray. From these facts, it is difficult to orderly transfer the leading portion of the sliced meat group M of thin sliced meat to the tray.

In this embodiment, since the sliced meat group M starts to fall from the side portion, the head portion and the tail portion in the stacking direction are in the direction orthogonal to the stacking direction (direction along the folding line) from the transfer belt 31. It falls while being peeled off in sequence. Therefore, even if the thickness of the sliced meat is reduced, the particularly conspicuous leading folding line portion tends to maintain a linear shape, and the entire sliced meat group M is transferred to the tray in an orderly manner.

In this embodiment, the end portion of the transfer conveyor 1 which is a shuttle conveyor is retracted so that the sliced meat group M is placed on the transfer belt 31, but for example, the transfer conveyor always has the end portion at a fixed position. The entire transfer machine 10 with the receiving plate 21 advanced is transferred to the transfer conveyor so that the sliced meat group M is delivered onto the transfer belt 31 in relation to the feed at the end of the transfer conveyor. It may be moved along the direction.

Further, in this embodiment, the tray transfer device 2 transfers the tray 3 to a suitable position, but the tray transfer device always transfers the tray 3 to the same position and moves the transfer device 10 to a suitable position with respect to the tray 3. You may.

In the present invention, the device for orderly transferring the sliced meat group from the transfer belt 31 to the tray 3 is realized by a simple mechanism by combining linear movements as in the above-described embodiment, and thus is a machine. It is easy to maintain and clean the machine every day, and the cost of the machine can be reduced.

The transfer device 10 in the present invention is particularly useful for transferring a group of sliced meats stacked in a scale shape, which is soft to be manually transferred and whose posture and shape are easily disturbed as in the present embodiment. However, the items to be transferred are not limited. In addition, the material and shape of each part can be changed as appropriate if they meet the functional requirements.

The present invention relates to a transfer device for transferring sliced meat into a tray.

As a method for transferring sliced meat into a tray related to the present invention, for example, there is one disclosed in Patent Document 1 by the applicant. According to this method, a group of sliced meat for each pack amount, which is arranged in a scale with a part stacked in front of the folding line and conveyed to the end of the conveyor, falls from the end of the conveyor. It is placed on the tray waiting below the end of the conveyor. At this time, in order to fill the sliced meat group at once while maintaining the posture of the sliced meat group, when the sliced meat group reaches the end portion of the conveyor, the end portion of the conveyor is retracted relatively rapidly and the sliced meat group is dropped into the tray. It is a configuration to make.

According to the method of Patent Document 1, it may differ depending on the meat quality and the temperature of the meat, but if the thickness of the sliced meat exceeds 2 mm, it is arranged on the tray in an orderly manner, but if it is 2 mm or less, the sliced meat The beginning and end of the fall may be disturbed. In order to solve this problem, the applicant has proposed Japanese Patent Application No. 2018-172016. In this proposal, the sliced meat group is transferred to a transfer belt formed narrower than the width of the inner bottom of the tray, and then at least one of the transfer belt and the tray is tilted to tilt the tip of the transfer belt. Described is a method of transferring a group of sliced meat into a tray by retracting the transfer belt while maintaining a state in which the portion and the inner bottom of the tray are in close contact with each other.

In addition, it was made known in the above proposal.
A moving plate that is freely moved back and forth on the support frame is hung in the front-rear direction, and a part of the contact surface side with the sliced meat is fixed to the support frame. A transfer belt configured to move forward and backward as it moves forward and backward in a straight line,
Although the details are not described in the above proposal, for example, Patent Documents 2 to 4 specifically disclose the above.

According to the configuration of Patent Document 2, the transfer belt has a retractable support plate material (corresponding to the “reception plate” in the present invention) wound in a ring shape, and the support plate material is advanced. By transferring an object such as food on the transfer belt on the upper surface side of the support plate material and then retracting the support plate material, the object on the transfer belt is transferred to a desired position. The transfer belt is folded and wound around the front end and the rear end of the support plate material, and one end and the other end of the transfer belt are overlapped on the upper surface side of the support plate and transferred. It is sandwiched between a fixing member erected on the main body (corresponding to the "machine frame" in the present invention) and a holding plate, and is fixed to the transfer main body by a plurality of fixing screws.

Japanese Patent Application Laid-Open No. 2019-64808 JP-A-2007-222153 Japanese Unexamined Patent Publication No. 2008-184265 JP-A-2017-214108

When viewed from the side in the stacking direction, a group of sliced meats in which sliced meats are stacked in a scaly shape and are stacked in a row is apparent because the number of sliced meats overlapping at the beginning and end is small. It can be said that the thickness is thin. According to the method of Patent Document 1, the end portion of the conveyor is retracted relatively rapidly, and the thin head portion of the sliced meat group is vigorously peeled off from the conveyor, so that the sliced meat group falls. It starts. Immediately before being peeled off, the sliced meat group is sticky to the extent that it does not slip off even if the conveyor is tilted 30 degrees from the horizontal, and the part that has begun to be peeled off falls in the air without being guided by anything. It becomes. Therefore, when the elasticity of the folding line portion at the head of the sliced meat group is large, the sliced meat group is peeled off from the conveyor while maintaining its shape and falls, so that it is not easily disturbed. However, if the elasticity of the folding line at the beginning is small due to the thinness of the sliced meat, etc., the adhesive force will be lost and the peeling from the conveyor will vary, and the shape of the beginning will not be maintained and the meat will fall. Since it comes into contact with the tray, the head part may be disturbed.

According to the proposal of Japanese Patent Application No. 2018-172016 by the applicant, the head portion of the sliced meat group that has begun to be transferred from the transfer belt to the tray is substantially continuous even after being peeled off from the transfer belt. Contact the inner bottom. Therefore, even if the thickness of the sliced meat becomes thin, the entire sliced meat group including the beginning portion and the ending portion in the stacking direction of the sliced meat is not easily disturbed and can be transferred to the tray in an orderly manner. However, if the tip of the transfer belt urged by using an elastic force such as a spring is applied to the inner bottom of the tray to follow the tray, the tray made of foamed resin may be scratched or cracked. To avoid this, contact the tip of the transfer belt with a weak force that does not cause scratches or cracks on the inner bottom of the tray, or keep a slight gap about the thickness of the sliced meat and keep the inner bottom of the tray. It is necessary to make it follow the shape of. Although these can be realized by combining a servomotor, a sensor, and the like to perform pressing control and position control of the tip of the transfer belt, the mechanism becomes complicated. With such a mechanism, there are problems such as difficulty in maintenance of the machine and daily cleaning of the machine, and an increase in the cost of the machine.

Daily cleaning is essential to maintain cleanliness at places that come into contact with food and places close to it, such as transfer belts. However, as disclosed in Patent Documents 2 to 4, transfer belts are used. Once configured, the transfer belt must be removed to clean both the front and back sides of the transfer belt and the support plate material (or "moving plate" and "slider"). According to the configurations disclosed in Patent Documents 2 to 4, the transfer belt can be removed only by removing or loosening the screws. However, in the mounting of the transfer belt, in order to maintain the function of the transfer, the tension of the transfer belt and the position in the width direction need to be reproduced substantially the same, but these are reproduced in the mounting. There is no description on how to do this. In practice, it is particularly difficult to reproduce the tension, and with a relatively large transfer belt as in Patent Document 4, it is particularly difficult to reproduce the tension.

In stores such as grocery stores, products in which sliced meat groups stacked in a scale are arranged on a tray are arranged manually because the orderly arrangement of sliced meat groups also plays a part in the product value. Is common, but automation is required from the viewpoint of production efficiency and hygiene. An object of the present invention is that even if the sliced meat is thin, the sliced meat group is systematically transferred to the tray by a simple method and mechanism, and the tension of the transfer belt can be reproduced and the transfer belt can be attached / detached. It is easy to do.

To. When this is repeated up to the last sliced meat m of a predetermined number of sheets to be placed on one tray 3, the sliced meat group M is placed on the conveyor 1 as shown in FIG.

In the meat slicer and the folding means, two rows of sliced meat m arranged in parallel are placed on the conveyor 1, but one row of sliced meat m can also be placed. A conveyor 1 is sent between the two-row or one-row sliced meat group M and the subsequent sliced meat group M so that the division becomes clear, and an interval is provided, and this is repeated to provide the sliced meat group. M is conveyed to the end of the transfer conveyor 1. In this embodiment, a two-row sliced meat group M will be used for explanation.

The folding means can change the folding position of the sliced meat. By setting the folding position to be outside the sliced meat, it is possible to obtain a scale-shaped sliced meat group M1 by the unfolded sliced meat m1, but the sliced meat m1 is often folded. Since it is thicker than the sliced meat m and has a large elasticity, it is not easily disturbed at the time of transfer. Therefore, in this embodiment, the sliced meat group M made of the folded sliced meat m will be described. As a reference, the unfolded sliced meat m1 is often 3 mm or more thick and is used for shogayakiya and pork cutlet.

The conveyor 1 is gently inclined so that the end portion descends toward the downstream side, and as shown by a virtual line in FIG. 4, the end portion of the conveyor 1 is terminated without changing the absolute position of the article placed on the upper surface of the conveyor. It is a shuttle conveyor (the drive part and the like are not shown) in which the part advances and retreats in the horizontal direction by a predetermined distance. The inclination of the conveyor 1 in FIG. 4 is about 21 degrees.

It is slidably supported by 24 and is movable in the exit / exit direction. The tip end portion of the receiving plate 21 in the advancing direction is a rounded end portion that is bent so as to overlap the lower surface side, and is considered so that it can be slidably contacted with the transfer belt 31. Further, the rear end portion of the receiving plate 21 in the advancing direction is bent downward by approximately 45 degrees so that the edge portion of the rear end of the receiving plate 21 does not hit the transfer belt 31 on the upper surface side of the receiving plate 21. ..

The transfer belt 31 is folded back from the upper surface of the receiving plate 21 at the tip of the receiving plate 21 and hung around the lower surface of the receiving plate 21.
Further, as shown in FIG. 16, the transfer belt 31 is formed so that the tip portions of both ends of the transfer belt 31 are folded back to form a tubular space surrounded by the transfer belt 31. It is glued to. The tubular spaces formed at both ends are engaged with the upper holding member 34 on the upper surface side of the receiving plate 21 and the upper engaging portion 32 which can be engaged with and disengaged from the upper holding member 34, and the other is engaged with the lower holding member 41 on the lower surface side of the receiving plate 21. It is a detachable lower engaging portion 33.

It can be released freely. The rail portion fixing pins 19 and 19 in this embodiment are index plungers, and the lower holding member rail 44 can be easily fixed and released to the support position simply by operating the knob of the index plunger.

When the lower holding member rail 44 is released from the support position, the lower holding member 41 can be inserted into the lower engaging portion 33 from the upstream side thereof. The lower holding member 41 is formed with notches that regulate the outside of both ends of the tubular portion of the lower engaging portion 33 by approximately 1 mm and hold the lower engaging portion 33 so that it is difficult to pull out. The lower engaging portion 33 is held in a substantially fixed position by hooking it on the notch while slightly deforming both ends, and it is easy to attach / detach.

The upper holding member 34 is a round bar (“holding bar” according to claim) that can be inserted into the upper engaging portion 32 and has a step on a part thereof, and is approximately 1 mm at both ends of the tubular portion of the upper engaging portion 32. The outer side has a large diameter, and when the transfer belt 31 is attached, both ends of the tubular portion are guided by a step in diameter and are held at a substantially fixed position. The outer ends of the large diameter are made smaller in diameter, and the upper holding member 34 is positioned within a range having a gap of approximately 0.5 mm at both ends with respect to the upper holding member locking portion 16, and the upper holding member fixing pin 17 , 17 fixed. The upper holding member fixing pins 17 and 17 in this embodiment are index plungers, and the upper holding member 34 can be easily attached to and detached from the upper holding member locking portion 16 and transferred by simply operating the knob of the index plunger. The position of the belt 31 in the width direction is reproduced as necessary and sufficient.

When attaching the transfer belt 31, after the lower engaging portion 33 of the transfer belt 31 is attached to the lower holding member 41, the lower holding member rail 44 is fixed to the support position and the lower holding member After the 41 is supported, the transfer belt 31 is folded back from the lower surface of the receiving plate 21 at the tip of the receiving plate 21 and hung around the upper surface of the receiving plate 21. Next, after the upper holding member 34 is inserted into the upper engaging portion 32, the upper holding member 34 is fixed so that the transfer belt 31 is wound around the cylindrical portion of the upper holding member locking portion 16. According to this procedure, the positions of both ends of the transfer belt 31 are substantially the same as those before the removal, and the tension of the transfer belt 31 is reproduced substantially the same as before the removal. When removing the transfer belt 31, the above procedure may be reversed.

Next, the interlocking means 51 will be described. The timing belt 53 hung on the timing pulleys 52, 52 rotatably supported by the receiving plate sliders 23, 23 is a timing belt fixing body in which a part thereof is fixed to a substantially central portion of the receiving plate guide rod 22. It is fixed at 54. The timing belt connecting body 55 into which the lower holding member guide rod 42 is inserted is rotatably sandwiched between the lower holding member sliders 43 and 43, and the timing belt 53 is rotatably sandwiched from the timing belt fixing body 54 in both directions. The timing belt 53 is fixed at a position having substantially the same length in.

According to the above configuration, as shown in FIG. 17, when the receiving plate 21 is moved by a distance S with respect to the machine frame 11 by an air cylinder (not shown), the lower side is moved via the timing belt 53. Since the holding member 41 is moved in the same direction with respect to the receiving plate 21 by the same distance S, the lower holding member 41 is moved by a distance 2S with respect to the machine frame 11. That is, since the lower holding member 41 is moved in the same direction at twice the speed of the receiving plate 21, the transfer belt 31 hung around the receiving plate 21 by the interlocking means 51 does not sag. Always in sliding contact with the tip.

As described above, the transfer machine 10 and the transfer belt 31 can be easily attached to and detached from each other during cleaning after the work is completed, and it is not necessary to adjust the tension when attaching the transfer belt 31 after cleaning. .. It should be noted that the transfer belt 31 may need to be adjusted in tension due to changes over time due to use and replacement due to deterioration or breakage. At this time, by loosening the bolt to which the upper holding member locking portion 16 is fixed, rotating it in the circumferential direction in FIG. 12 and tightening the bolt, the winding angle of the transfer belt 31 to the upper holding member locking portion 16 is set. Changes and can be adjusted to the appropriate tension.

A tray transfer device 2 for transferring the tray 3 along a direction orthogonal to the transfer direction of the transfer conveyor 1 is provided below the receiving plate 21 in the transfer device 10 configured as described above. The tray 3 is transferred to a suitable position by the tray transfer device 2 and lifted so that the sliced meat group M is transferred to a substantially central portion in the tray transfer direction. The tray transfer device 2 has a height that is not affected by the transfer operation of the tray transfer device 2 after transferring one of the corresponding trays 3 and 3 to a suitable position in the sliced meat groups M and M in the two rows. Lift it up. Then, by transferring the other to a suitable position and lifting it up, both the trays 3 and 3 corresponding to the sliced meat groups M and M in the two rows are transferred to a suitable position.

The transfer method of the transfer device configured in this manner in this embodiment will be described with reference to the drawings. FIG. 1 shows a state in which the end portion of the transport conveyor 1 is retracted as shown in FIG. 4, and the sliced meat group M is placed on the transfer belt 31 on the upper surface of the receiving plate 21 from the transport conveyor 1. The gap between the lower surface of the terminal portion of the transport conveyor 1 and the transfer belt 31 on the upper surface of the receiving plate 21 is approximately 2 mm, and after the head portion of the sliced meat group M that has begun to leave the terminal portion of the transport conveyor 1. Is sequentially transferred while contacting the transfer belt 31 on the upper surface of the receiving plate 21 substantially continuously, so that the transfer belt 31 is neatly placed on the transfer belt 31 while suppressing disturbance. At this time, the trays 3 and 3 are transferred to a suitable position below the receiving plates 21 and 21 by the tray transfer device 2 and lifted.

Next, the receiving plate 21 is retracted along the direction orthogonal to the stacking direction of the sliced meat m. As described above, since the transfer belt 31 is always in sliding contact with the tip of the receiving plate 21 without sagging, the transfer belt 31 on the upper surface of the receiving plate 21 does not change its position relative to the lower surface of the sliced meat group M. As they are peeled off, the sliced meat group M begins to fall from the lateral portion in the stacking direction as shown in FIGS. 5 and 6.

Here, in FIG. 10 when the sliced meat group M is viewed from the side in the stacking direction, the number of overlapping sliced meats is the beginning portion (left end in FIG. 10) and the end portion (FIG. 10) as compared with the substantially four pieces of the central portion. At the right end of 10), the apparent thickness is as thin as two. More specifically, the apparent thickness of the central portion of the sliced meat group M is about 3 to 6 sliced meats if it is small depending on the degree of overlap of the sliced meats m, but it is about 6 sheets if it is large, but the leading portion with a folding line. The apparent thickness is about 2 slices of meat, and the apparent thickness of the tail portion is 2 or 1 slice of meat depending on the folding position.

As a reference, in the sliced meat group M1 made of unfolded sliced meat m1, the apparent thickness of the central portion is about 2 to 4 slices of meat, and the thickness of the beginning portion and the ending portion is 1 sliced meat. It is for one sheet.

According to the method of Patent Document 1, the leading folding line portion of the sliced meat group M in the stacking direction is peeled off from the conveyor at substantially the same time. As the thickness of the sliced meat decreases, the elasticity of the folding line portion decreases, so that the peeling method of the folding line portion that adheres to the conveyor to some extent varies. In addition, it is difficult to keep the folding line part in a straight shape due to its small elasticity even when the leading part is falling or comes into contact with the tray. From these facts, it is difficult to orderly transfer the leading portion of the sliced meat group M of thin sliced meat to the tray.

In this embodiment, since the sliced meat group M starts to fall from the side portion, the head portion and the tail portion in the stacking direction are in the direction orthogonal to the stacking direction (direction along the folding line) from the transfer belt 31. It falls while being peeled off in sequence. Therefore, even if the thickness of the sliced meat is reduced, the particularly conspicuous leading folding line portion tends to maintain a linear shape, and the entire sliced meat group M is transferred to the tray in an orderly manner.

In this embodiment, the end portion of the transfer conveyor 1 which is a shuttle conveyor is retracted so that the sliced meat group M is placed on the transfer belt 31, but for example, the transfer conveyor always has the end portion at a fixed position. The entire transfer machine 10 with the receiving plate 21 advanced is transferred to the transfer conveyor so that the sliced meat group M is delivered onto the transfer belt 31 in relation to the feed at the end of the transfer conveyor. It may be moved along the direction.

Further, in this embodiment, the tray transfer device 2 transfers the tray 3 to a suitable position, but the tray transfer device always transfers the tray 3 to the same position and moves the transfer device 10 to a suitable position with respect to the tray 3. You may.

In the present invention, the device for orderly transferring the sliced meat group from the transfer belt 31 to the tray 3 is realized by a simple mechanism by combining linear movements as in the above-described embodiment, and thus is a machine. It is easy to maintain and clean the machine every day, and the cost of the machine can be reduced.

The transfer device 10 in the present invention is particularly useful for transferring a group of sliced meats stacked in a scale shape, which is soft to be manually transferred and whose posture and shape are easily disturbed as in the present embodiment. However, the items to be transferred are not limited. In addition, the material and shape of each part can be changed as appropriate if they meet the functional requirements.

The present invention relates to a transfer device for transferring sliced meat into a tray.

As a method for transferring sliced meat into a tray related to the present invention, for example, there is one disclosed in Patent Document 1 by the applicant. According to this method, a group of sliced meat for each pack amount, which is arranged in a scale with a part stacked in front of the folding line and conveyed to the end of the conveyor, falls from the end of the conveyor. It is placed on the tray waiting below the end of the conveyor. At this time, in order to fill the sliced meat group at once while maintaining the posture of the sliced meat group, when the sliced meat group reaches the end portion of the conveyor, the end portion of the conveyor is retracted relatively rapidly and the sliced meat group is dropped into the tray. It is a configuration to make.

According to the method of Patent Document 1, it may differ depending on the meat quality and the temperature of the meat, but if the thickness of the sliced meat exceeds 2 mm, it is arranged on the tray in an orderly manner, but if it is 2 mm or less, the sliced meat The beginning and end of the fall may be disturbed. In order to solve this problem, the applicant has proposed Japanese Patent Application No. 2018-172016. In this proposal, the sliced meat group is transferred to a transfer belt formed narrower than the width of the inner bottom of the tray, and then at least one of the transfer belt and the tray is tilted to tilt the tip of the transfer belt. Described is a method of transferring a group of sliced meat into a tray by retracting the transfer belt while maintaining a state in which the portion and the inner bottom of the tray are in close contact with each other.

In addition, it was made known in the above proposal.
A moving plate that is freely moved back and forth on the support frame is hung in the front-rear direction, and a part of the contact surface side with the sliced meat is fixed to the support frame. A transfer belt configured to move forward and backward as it moves forward and backward in a straight line,
Although the details are not described in the above proposal, for example, Patent Documents 2 to 4 specifically disclose the above.

According to the configuration of Patent Document 2, the transfer belt has a retractable support plate material (corresponding to the “reception plate” in the present invention) wound in a ring shape, and the support plate material is advanced. By transferring an object such as food on the transfer belt on the upper surface side of the support plate material and then retracting the support plate material, the object on the transfer belt is transferred to a desired position. The transfer belt is folded and wound around the front end and the rear end of the support plate material, and one end and the other end of the transfer belt are overlapped on the upper surface side of the support plate and transferred. It is sandwiched between a fixing member erected on the main body (corresponding to the "machine frame" in the present invention) and a holding plate, and is fixed to the transfer main body by a plurality of fixing screws.

In Patent Document 3, a fixed portion in which both ends of a belt (corresponding to the "transfer belt" in the present invention) around which a moving plate (corresponding to the "reception plate" in the present invention) is overlapped is defined as a concave portion and a convex portion. A configuration is described in which the portions are sandwiched and fixed from above and below with a fitting to be fitted, and then connected and fixed with a connecting tool such as a bolt. Further, in Patent Document 4, a sheet (corresponding to the "transfer belt" in the present invention) in which a slider (corresponding to the "reception plate" in the present invention) is rotated is sandwiched between two sandwiching materials, and both sandwiching materials are used. An example is described in which a method of fixing both ends with a clamp lever which is a stopper and an intermediate portion of both holding materials with a toggle clamp which is a stopper is used for a relatively large device.

Japanese Patent Application Laid-Open No. 2019-64808 JP-A-2007-222153 Japanese Unexamined Patent Publication No. 2008-184265 JP-A-2017-214108

When viewed from the side in the stacking direction, a group of sliced meats in which sliced meats are stacked in a scaly shape and are stacked in a row is apparent because the number of sliced meats overlapping at the beginning and end is small. It can be said that the thickness is thin. According to the method of Patent Document 1, the end portion of the conveyor is retracted relatively rapidly, and the thin head portion of the sliced meat group is vigorously peeled off from the conveyor, so that the sliced meat group falls. It starts. Immediately before being peeled off, the sliced meat group is sticky to the extent that it does not slip off even if the conveyor is tilted 30 degrees from the horizontal, and the part that has begun to be peeled off falls in the air without being guided by anything. It becomes. Therefore, when the elasticity of the folding line portion at the head of the sliced meat group is large, the sliced meat group is peeled off from the conveyor while maintaining its shape and falls, so that it is not easily disturbed. However, if the elasticity of the folding line at the beginning is small due to the thinness of the sliced meat, etc., the adhesive force will be lost and the peeling from the conveyor will vary, and the shape of the beginning will not be maintained and the meat will fall. Since it comes into contact with the tray, the head part may be disturbed.

According to the proposal of Japanese Patent Application No. 2018-172016 by the applicant, the head portion of the sliced meat group that has begun to be transferred from the transfer belt to the tray is substantially continuous even after being peeled off from the transfer belt. Contact the inner bottom. Therefore, even if the thickness of the sliced meat becomes thin, the entire sliced meat group including the beginning portion and the ending portion in the stacking direction of the sliced meat is not easily disturbed and can be transferred to the tray in an orderly manner. However, if the tip of the transfer belt urged by using an elastic force such as a spring is applied to the inner bottom of the tray to follow the tray, the tray made of foamed resin may be scratched or cracked. To avoid this, contact the tip of the transfer belt with a weak force that does not cause scratches or cracks on the inner bottom of the tray, or keep a slight gap about the thickness of the sliced meat and keep the inner bottom of the tray. It is necessary to make it follow the shape of. Although these can be realized by combining a servomotor, a sensor, and the like to perform pressing control and position control of the tip of the transfer belt, the mechanism becomes complicated. With such a mechanism, there are problems such as difficulty in maintenance of the machine and daily cleaning of the machine, and an increase in the cost of the machine.

Daily cleaning is essential to maintain cleanliness at places that come into contact with food and places close to it, such as transfer belts. However, as disclosed in Patent Documents 2 to 4, transfer belts are used. Once configured, the transfer belt must be removed to clean both the front and back sides of the transfer belt and the support plate material (or "moving plate" and "slider"). According to the configurations disclosed in Patent Documents 2 to 4, the transfer belt can be removed only by removing or loosening the screws. However, in the mounting of the transfer belt, in order to maintain the function of the transfer, the tension of the transfer belt and the position in the width direction need to be reproduced substantially the same, but these are reproduced in the mounting. There is no description on how to do this. In practice, it is particularly difficult to reproduce the tension, and with a relatively large transfer belt as in Patent Document 4, it is particularly difficult to reproduce the tension.

In stores such as grocery stores, products in which sliced meat groups stacked in a scale are arranged on a tray are arranged manually because the orderly arrangement of sliced meat groups also plays a part in the product value. Is common, but automation is required from the viewpoint of production efficiency and hygiene. An object of the present invention is that even if the sliced meat is thin, the sliced meat group is systematically transferred to the tray by a simple method and mechanism, and the tension of the transfer belt can be reproduced and the transfer belt can be attached / detached. It is easy to do.

Changes and can be adjusted to the appropriate tension.

A tray transfer device 2 for transferring the tray 3 along a direction orthogonal to the transfer direction of the transfer conveyor 1 is provided below the receiving plate 21 in the transfer device 10 configured as described above. The tray 3 is transferred to a suitable position by the tray transfer device 2 and lifted so that the sliced meat group M is transferred to a substantially central portion in the tray transfer direction. The tray transfer device 2 has a height that is not affected by the transfer operation of the tray transfer device 2 after transferring one of the corresponding trays 3 and 3 to a suitable position in the sliced meat groups M and M in the two rows. Lift it up. Then, by transferring the other to a suitable position and lifting it up, both the trays 3 and 3 corresponding to the sliced meat groups M and M in the two rows are transferred to a suitable position.

The transfer method of the transfer device configured in this manner in this embodiment will be described with reference to the drawings. FIG. 1 shows a state in which the end portion of the transport conveyor 1 is retracted as shown in FIG. 4, and the sliced meat group M is placed on the transfer belt 31 on the upper surface of the receiving plate 21 from the transport conveyor 1. The gap between the lower surface of the terminal portion of the transport conveyor 1 and the transfer belt 31 on the upper surface of the receiving plate 21 is approximately 2 mm, and after the head portion of the sliced meat group M that has begun to leave the terminal portion of the transport conveyor 1. Is sequentially transferred while contacting the transfer belt 31 on the upper surface of the receiving plate 21 substantially continuously, so that the transfer belt 31 is neatly placed on the transfer belt 31 while suppressing disturbance. At this time, the trays 3 and 3 are transferred to a suitable position below the receiving plates 21 and 21 by the tray transfer device 2 and lifted.

Next, the receiving plate 21 is retracted along the direction orthogonal to the stacking direction of the sliced meat m. As described above, since the transfer belt 31 is always in sliding contact with the tip of the receiving plate 21 without sagging, the transfer belt 31 on the upper surface of the receiving plate 21 does not change its position relative to the lower surface of the sliced meat group M. As they are peeled off, the sliced meat group M begins to fall from the lateral portion in the stacking direction as shown in FIGS. 5 and 6.

Here, in FIG. 10 when the sliced meat group M is viewed from the side in the stacking direction, the number of overlapping sliced meats is the beginning portion (left end in FIG. 10) and the end portion (FIG. 10) as compared with the substantially four pieces of the central portion. At the right end of 10), the apparent thickness is as thin as two. More specifically, the apparent thickness of the central portion of the sliced meat group M is about 3 to 6 sliced meats if it is small depending on the degree of overlap of the sliced meats m, but it is about 6 sheets if it is large, but the leading portion with a folding line. The apparent thickness is about 2 slices of meat, and the apparent thickness of the tail portion is 2 or 1 slice of meat depending on the folding position.

As a reference, in the sliced meat group M1 made of unfolded sliced meat m1, the apparent thickness of the central portion is about 2 to 4 slices of meat, and the thickness of the beginning portion and the ending portion is 1 sliced meat. It is for one sheet.

According to the method of Patent Document 1, the leading folding line portion of the sliced meat group M in the stacking direction is peeled off from the conveyor at substantially the same time. As the thickness of the sliced meat decreases, the elasticity of the folding line portion decreases, so that the peeling method of the folding line portion that adheres to the conveyor to some extent varies. In addition, it is difficult to keep the folding line part in a straight shape due to its small elasticity even when the leading part is falling or comes into contact with the tray. From these facts, it is difficult to orderly transfer the leading portion of the sliced meat group M of thin sliced meat to the tray.

In this embodiment, since the sliced meat group M starts to fall from the side portion, the head portion and the tail portion in the stacking direction are in the direction orthogonal to the stacking direction (direction along the folding line) from the transfer belt 31. It falls while being peeled off in sequence. Therefore, even if the thickness of the sliced meat is reduced, the particularly conspicuous leading folding line portion tends to maintain a linear shape, and the entire sliced meat group M is transferred to the tray in an orderly manner.

In this embodiment, the end portion of the transfer conveyor 1 which is a shuttle conveyor is retracted so that the sliced meat group M is placed on the transfer belt 31, but for example, the transfer conveyor always has the end portion at a fixed position. The entire transfer machine 10 with the receiving plate 21 advanced is transferred to the transfer conveyor so that the sliced meat group M is delivered onto the transfer belt 31 in relation to the feed at the end of the transfer conveyor. It may be moved along the direction.

Further, in this embodiment, the tray transfer device 2 transfers the tray 3 to a suitable position, but the tray transfer device always transfers the tray 3 to the same position and moves the transfer device 10 to a suitable position with respect to the tray 3. You may.

In the present invention, the device for orderly transferring the sliced meat group from the transfer belt 31 to the tray 3 is realized by a simple mechanism by combining linear movements as in the above-described embodiment, and thus is a machine. It is easy to maintain and clean the machine every day, and the cost of the machine can be reduced.

The transfer device 10 in the present invention is particularly useful for transferring a group of sliced meats stacked in a scale shape, which is soft to be manually transferred and whose posture and shape are easily disturbed as in the present embodiment. However, the items to be transferred are not limited. In addition, the material and shape of each part can be changed as appropriate if they meet the functional requirements.
