Description

The present invention relates to an apparatus for stacking meat pieces in a meat slicer in which meat pieces periodically cut out from a meat slicer are received at the start end of a belt conveyor and dropped from the end portion into a tray.

For example, Patent Document 1 discloses an apparatus for stacking meat pieces in a conventional meat slicer related to the present invention.
The assembling apparatus of Patent Document 1 repeats the operation in which the belt conveyor receives a piece of meat cut out from the slicer and repeats a small feed to partially overlap, and when it reaches a predetermined number of sheets, it feeds a large feed and opens an interval. When the most advanced sliced meat piece reaches the serving position and slightly overlaps the peeled body, it is detected by the sensor, the tip of the belt conveyor moves backward, and a predetermined number of pieces of meat are placed in the tray (corresponding to the tray). It is the structure which drops and arrange | positions with the attitude | position mounted on the conveyor.

In the slicer in which the meat pieces are periodically cut out by the self-revolving round blade described in the above-mentioned Patent Document 1, the end portion of the belt conveyor is moved backward by a predetermined number of meat pieces and the pieces of meat pieces are dropped, It is desirable to complete the operation of returning to the position until the next piece of meat is cut out. If it is not possible, the cutting should be temporarily stopped or the cutting cycle should be lengthened to reduce the efficiency accordingly. Become.
In addition, when the meat pieces are soft and sticky raw meat, they adhere strongly to the belt surface, and the rigidity of the meat pieces is low, so they slide down ahead of the overlapping part to the peeled body, and the falling posture into the saucer is disturbed In addition, there is a risk of carrying around due to adhesion to the belt surface.

Patent Document 2 discloses the transfer of a piece of meat that is transferred into the tray by rotating a relay roller in the same direction to the end of a belt conveyor for transferring the piece of meat cut out from the slicer by the applicant to the outer peripheral surface. In the apparatus, a technique is disclosed in which a tray disposed below a relay roller is appropriately moved by a tray transport conveyor in a meat piece transfer direction so that a part of the meat pieces is superposed and received.
In this case, it is convenient if the tray conveyance direction is the same as the meat piece transfer direction, but if the tray is orthogonal to the meat piece transfer direction, it is difficult to configure the tray conveyor.

Similarly, in Patent Document 3 by the present applicant, in a meat slicer configured to feed sliced meat pieces cut out at a predetermined width into a tray having a bottom width dimension substantially the same as the width dimension of the sliced meat pieces, There is disclosed a technique in which a guide for guiding to a dropping position is provided, and a slice is received and averaged and placed at different positions by shifting a tray while being transferred to an adjacent cut-out opening. ([0063], FIG. 10 etc.)
However, with this configuration, it is not possible to average when receiving multiple slices of meat from the same cutout.

In view of the above-described problems associated with the conventional apparatus for stacking sliced meat pieces, the present invention can efficiently arrange meat on a tray in an orderly manner without moving the tray. An object of the present invention is to provide an apparatus for stacking meat pieces in a slicer.

The present invention receives a meat piece periodically cut out with a width dimension regulated by the left and right side walls by the relative movement of the meat box with the side walls standing on the left and right and the cutter, and the width dimension is substantially the same as the width dimension. In meat slicer stacking equipment in a meat slicer equipped with a belt conveyor that drops into a tray of the same width dimension, the end of the belt conveyor is positioned above the tray in the direction of the meat piece in relation to the cutting of the meat piece. The meat slicer in the meat slicer is configured to be reciprocated so that a desired number of cut pieces of meat are sequentially dropped at different positions in the tray for each cut. It is considered as a tray mounting device.
In addition, a peeling roller that rotates in the same direction as the conveying direction installed at the terminal end in a state of sliding contact with the conveyor surface of the belt conveyor to peel off the flesh is provided, and the peeling roller is in sliding contact with the conveyor surface of the belt conveyor. It is preferable to be configured to reciprocate while maintaining this state.
Furthermore, it is preferable that at least the meat piece to be stacked at the top is dropped only in one of the forward path and the return path in the reciprocating motion of the end portion of the belt conveyor.

According to the present invention, in relation to the cutting of the meat pieces, the tray is reciprocated at the upper position of the tray along the conveying direction of the meat pieces, and the trays are cut for each amount of meat pieces to be cut at a desired number of times. Since it is dropped sequentially at different locations in the length direction, the placing work in a state of being leveled in the tray can be performed efficiently.
Further, when the end portion of the belt conveyor is reciprocated while keeping the state in which the peeling roller is in sliding contact with the conveying surface of the conveyor, the belt conveyor is neatly arranged without disturbance.

With reference to the drawings, a description will be given of an embodiment of the apparatus for stacking meat pieces in the meat slicer according to the present invention.

As shown in FIGS. 1 and 5, the apparatus for stacking meat pieces in the meat slicer according to the present invention includes a slice block A for cutting the meat piece m from the meat M, and the input of the cut piece m to the receiving tray. A belt conveyor block B that transports to a position and a tray transport block C that feeds a tray to a loading position where meat pieces are arranged.

First, the configuration of the slice block A will be described mainly with reference to FIGS.
The meat box 3 supported by the machine base 1 and reciprocated within a predetermined range in the vertical direction by the crank mechanism 2 has a bottom conveyor 4 at the bottom and side conveyors 5 and 5 at the left and right sides, respectively. The width of the meat block M that is sent out by the distance between the side walls is regulated by the conveying surfaces of the left and right side conveyors 5 and 5 facing each other.
Further, the upper conveyor 6 is stretched on the upper surface of the meat box 3 while leaving a supply space (12 in FIG. 5) of the meat lump M formed near the meat feed start end. As shown in Fig. 4, four sides are constituted by a conveyor.
Accordingly, the meat mass M supplied from the supply space 12 is surrounded by the conveyor from all sides, and is reliably fed out by each conveyor driven by a drive device (not shown), so that the piece m cut out at a time is quantified. .

At the front end of the meat box 3 configured in this manner, a contact plate 7 whose position is adjusted in the feeding direction to regulate the slice thickness is provided. The band knife 8 is stretched by being wound around pulleys 11 and 11 (FIG. 5) supported by the shaft, and when the meat box 3 reciprocating in the vertical direction moves up, it is placed on the meat box 3 and at least The front end of the meat chunk M, whose width direction is regulated by the left and right side walls, is sliced by the band knife 8 and cut out as a meat piece m from the cutout opening.

Next, the belt conveyor block B that receives the cut meat pieces m will be described mainly with reference to FIG.
The belt conveyor 9 that receives the cut piece m along the outer peripheral surface has a width dimension corresponding to the width of the cut opening (interval between the left and right side walls of the meat box 3), and extends appropriately in the direction in which the piece m is cut out. And stretched.
Of the plurality of pulleys around which the belt conveyor 9 is wound, the pulley 10 positioned below is connected to a motor (both not shown) installed on the conveyor frame.
Further, the starting end of the belt conveyor 9 may be in a position where the cut piece m can be reliably received. However, in this embodiment, the pulleys 13a,. The meat piece m to be cut is run in synchronism with the upward movement of the meat box 3, and is arranged in a relatively gentle arc shape so that it can be smoothly received in the spread state, and attached before the meat piece m is cut off. The cut piece is brought close to the cutout so that it can be received, so that the meat piece m is not attached to the band knife 8 and pulled. The plurality of pulleys 13a... May be replaced by a single pulley having a large diameter, or may be constituted by a simple guide plate.

Further, the belt conveyor 9 may be made of a thin and tough material to make the pulley 13b of the folded portion at the end portion as small as possible, or as a knife edge to prevent the meat piece m from being carried around. In the present embodiment, in consideration of the durability of the belt conveyor 9, the pulley 13b at the end portion is made relatively large, and in order to prevent the pulley 13b from adhering and carrying around, the folded portion has a relatively small diameter (diameter 5 to 50 mm). ) Is connected to a motor so as to slide in contact with the transport surface of the belt conveyor 9 and rotate in the same direction as the transport direction.
Since the peeling roller 14 is rotated in the same direction as the conveying direction (traveling direction) of the belt conveyor 9, the traveling direction of the outer peripheral surface of the peeling roller 14 in a state of sliding contact with the conveying surface of the belt conveyor 9 is the same as that of the belt conveyor 9. The direction is opposite to the traveling direction, and the piece m attached to the transport surface is peeled off and dropped. Although not shown, the peeling roller 14 is desirably provided with a large number of fine grooves on the outer peripheral surface in the axial direction so as to enhance the peeling effect.

The end portion of the belt conveyor 9 is the length dimension of the tray at a position above the tray along the transport direction together with the pulley 13b at the end portion and the tension pulley 13c following the pulley 13b while the transport surface is in sliding contact with the peeling roller 14. It is configured to be able to reciprocate inside.
That is, details of the support shaft 15 of the pulley 13b at the end of the belt conveyor 9, the tension pulley 13c, and the peeling roller 14 are omitted, and only one side is shown, but slide bearings attached to the left and right conveyor frames, respectively. 17 and is integrally supported by a slide bar 18 that is slidable along the conveying direction.
On the other hand, the other end of the slide bar 18 is connected to a swing arm 20 attached to a rotating shaft 19 supported on the conveyor frame via a universal joint 21.
The large gear 22 fixed to the rotating shaft 19 meshes with the small gear 24 fixed to the output shaft of the motor 23 with a speed reducer attached to the conveyor frame.
When the motor 23 is driven in association with the cutout of the meat piece, the swing arm 20 is swung and the guide bar 18 is slid. Moved to.

Next, the tray transport block C into which the meat pieces m that have been peeled off by the peeling roller 14 at the end of the belt conveyor 9 will be described.
The tray transport block C for supplying the tray 25 to the position where the meat piece m falls below the peeling roller 14 is inclined toward the machine body side where a large number of empty trays are stacked and stored as shown in FIGS. A tray storage tank 26, a take-out device 27 that takes out the stacked trays 25 one by one from the lowermost end, and a roller chain that conveys the taken-out tray 25 to a position for receiving a piece of meat m below the end of the belt conveyor 9. It is comprised from the tray conveyance apparatus 28 which consists of endless belts. The tray conveying device 28 is disposed so as to be orthogonal to the conveying direction of the belt conveyor 9.

The details of the tray transport device 28 will be described. A roller chain 30 is wound around sprockets 29 and 29 that are pivotally supported on the left and right positions of the machine frame of the tray transport device 28, and one of the sprockets 29 is connected to a drive motor. The A large number of projecting pieces 31... Which are brought into contact with the rear wall of the tray 25 to be conveyed are attached to the roller chain 30 at intervals of at least the width of the tray 25. The projecting piece 31 is arranged so as to be positioned substantially on the center line in the length direction of the tray 25, but the traveling line of the roller chain 30 is arranged so as to be biased to one side. This is because the passage of the projecting piece 31 is continuously opened in the receiving plates 32, 32 stretched on the tray conveying surface so as to receive the bottom surface of the tray 25, but small pieces of spilled or the like fall from this opening. This is to prevent the roller chain 30 from being caught. Also, with respect to the structure of the machine frame of the tray transporting device 28, the lower part of the opening is opened as much as possible to prevent accumulation of small pieces that fall off.

Usually, meat pieces m sliced to a thickness of about 1 to 4 mm with a meat slicer are placed on a small tray made of foamed resin within a range of about 100 to 300 g and wrapped in a transparent resin film in units of about 100 g. Sold at stores.
On the other hand, the amount of the piece of meat m cut out at a time from the meat slicer is set to be relatively small. For example, if the thickness of the mainstream of the sliced meat piece is about 2 mm, it is about 50 g. It will be arranged on one tray.
A tray whose length dimension is changed along the conveying direction of the meat according to the amount of serving is used, but when using a large tray and placing many pieces of meat m many times, lapping after serving There is no problem in the process, and in order to improve the appearance at the store, it is required to arrange the trays in a uniform and uniform state.

Note that the tray 25 has a constant width dimension orthogonal to the conveying direction of the piece m by the belt conveyor 9 and changes only the length dimension along the conveying direction so as to correspond to the loading amount. It is easy to manufacture trays 25 of various sizes, management of the trays 25 having different sizes and distribution can be rationalized, and the width of the tray 25 does not change even in the tray 25 transfer device, so it is possible to cope with each size. Easy and simple to configure.
Further, the tray transport path in the transport portion of the tray 25 can be configured simply by adjusting the length of the large and small trays 25 in the transport direction of the meat pieces m and supplying them to the position where the meat pieces m are dropped. There is.

In the present embodiment, the end portion of the belt conveyor 9 passes through the intermediate position (2) indicated by the dotted line in the forward path from the start position (1) indicated by the solid line shown in FIG. Cutting out the piece m from the end position (3) to the start position (1) through the intermediate position (2) on the return path from the end position (3) shown in (a), that is, the upper movement of the meat box 3 In conjunction with the above, the peeling roller 14 is sequentially moved along the conveying direction of the meat pieces m (the length direction of the tray 25).

At that time, the end of the belt conveyor 9 is temporarily stopped at each position, and it is appropriately selected whether it is dropped at a time for each piece of meat m to be cut at a time, or dispersed and dropped while moving at a slow speed. You may be able to do it.

In any case, the range in which the end portion of the belt conveyor 9 reciprocates is within the length dimension along the conveying direction of the meat piece m in the tray 25 to be used.
The number of times the meat piece m is dropped is not limited to three times in the present embodiment, and can be set as appropriate depending on the size of the tray 25 and the desired state of placement in the tray 25, but the meat piece m cut out at a time. The amount is set in units.
For example, when processing chopped meat, a plurality of relatively small meat chunks M to be sliced are packed in the meat box 3 so that the cut surface is uniform, and the amount of pieces of meat m to be cut at a time is quantified. By doing so, the setting of the amount of deposit becomes easy, and the amount of deposit on the tray 25 can be made uniform.

In the meat slicer of the meat slicer of the present embodiment configured as described above, when the meat box 3 on which the meat chunk M is placed is reciprocated in the vertical direction by the crank mechanism 2 and moved upward, the band knife 8, the front end portion of the meat block M regulated by at least the left and right side walls is cut and cut out from the cut-out opening as a piece of meat m.
The conveyor belt 9 receives an amount of the meat piece m cut out at a time, but if the conveyor belt 9 is attached to the surface of the start end while being moved in synchronization with the upward movement of the meat box 3, it is surely kept spread. You can receive it. The meat piece m is conveyed to the end portion, peeled off by the peeling roller 14 and dropped into the tray 25.

At the start of work, it is preferable that the end portion of the belt conveyor 9 is set so as to be located at either the start position (1) or the end position (3) in the reciprocating motion.
Assuming that the piece m is dropped at three locations in the tray 25 as shown in FIG. 4 and the end of the belt conveyor 9 is at the start position (1) in the reciprocating motion at the start of work, The meat piece m is dropped to the start end position side in the tray 25 shown in 1), and the end portion of the belt conveyor 9 is moved to the vicinity of the intermediate position (2) until the next meat piece m is cut out, and then cut out. The meat piece m to be dropped is dropped to the intermediate position of the tray 25. Similarly, the piece of meat m is dropped at the end position (3) in the tray 25 to complete the placement on one tray 25.
Next, the end portion of the belt conveyor 9 becomes the return path in the reciprocating motion shown in FIG. 4 (a), and is dropped at three different locations in the tray 25 for each piece of meat m sequentially cut out at one time. Dispose so that it is in the state.
In this way, the tray 25 is arranged for each of the trays 25 alternately in the forward path and the return path in the reciprocating motion of the end portion of the belt conveyor 9, and the tray 25 is sent out of the machine by the roller chain 30. Subsequent empty trays 25 are supplied and the assembling work is continuously performed. A series of these operations are performed within a period in which the meat box 3 reciprocates, and control is also performed based on the reciprocation of the meat box 3.
Thus, if both the forward path and the return path in the reciprocating motion of the end portion of the conveyor 9 are arranged on the tray 25, an efficient operation can be performed.

In the present embodiment, as described above, an example is shown in which three pieces of the meat pieces m cut out once are arranged on one tray 25. However, when more pieces are arranged, the end portion of the belt conveyor 9 is arranged. The length of the tray 25 may be reduced by reducing the amount of movement per stroke and reducing the interval, or by dropping the end portion of the tray 25 once in a reciprocating manner. It is set as appropriate depending on the size and the desired amount of application.

In addition, when a plurality of cut pieces of meat are to be placed on a single tray, at least the meat pieces to be placed at the top should be at the end of the belt conveyor, even if they are placed in multiple layers. If it is made to drop only in one of the forward path and the return path in the reciprocating motion of the section, it is preferable because the appearance shapes of the meat pieces stacked on one tray are similarly aligned. In this case, it is preferable to quickly return either the forward path or the backward path where the meat pieces are not dropped.

As described above, according to the present invention, the end portion of the belt conveyor 9 is sequentially reciprocated in relation to the cutting of the sliced piece m of the slicer, and the desired number of pieces of the pieces of meat m are leveled on one tray 25. While the tray 25 can be left in a fixed position during that time, the tray transport device can be configured simply, and after the tray 8 is transported in the direction perpendicular to the transport direction of the meat pieces m Conveniently, it is configured to be carried out in the same direction as it is.

Further, the end portion of the belt conveyor 9 is sequentially moved in small increments with a relatively small amount of movement within the length of the tray 25 in relation to the reciprocation of the meat slicer 3 of the meat slicer, that is, the cutting of the meat piece m. Since it is dropped for each relatively small piece of meat m cut out at once, it moves compared to the one that moves the tray length dimension back and forth at once and drops multiple groups of meat pieces together as in Patent Document 1. However, the efficiency is not constrained because the cutting cycle can be shortened without moving it momentarily.

In addition, if the cut piece m is attached to the front end portion of the belt conveyor 9 before being cut off by approaching the cut-out opening, it is not shifted to the falling position of the end portion and is synchronized with the cut-out. Therefore, there is no need for a sensor that senses that the meat piece m has arrived at the drop position, and the control is performed in relation to the timing of cutting, so that the meat m is surely placed at a predetermined position in the tray 25 without being disturbed. be able to.
