Description

  The present invention relates to an improvement in a sliced meat piece transfer device in a meat slicer that slices meat such as cows and pigs.

A technique related to the present invention is disclosed in Japanese Patent Laid-Open No. 2003-48192 (Patent Document 1) by the present applicant.
In the sliced meat piece transfer device described in this publication, the sliced meat pieces are transferred at a predetermined position by transferring a plurality of rows of needle-like protrusions on the outer periphery in the width direction with a plurality of rotary transfer bodies created in the width direction. A transfer piece (tool) is disclosed in which the body is stopped and peeled off from the back side of the sliced meat piece in a stopped state.

  In addition, it is also described that the slice meat piece is reversely transferred in either a folded state or an expanded state by changing the stop position of the slice meat piece.

  In the configuration in which the rotary transfer body for transferring the sliced meat pieces is stopped and the sliced meat pieces in the stopped state are peeled off from the back side with the transfer pieces, the sliced meat pieces to be cut out are prevented from being disturbed by the cutter. Therefore, when the sliced meat piece is strongly pressed against the needle-like protrusion by the pressing tool, the needle tip is deeply pierced into the sliced meat piece, and it is difficult to peel off with the transfer piece.

  In addition, sliced meat pieces such as beef loin that are relatively large and easily torn when thinly sliced may be caught by needle-like protrusions when being peeled off by a transfer piece.

  On the other hand, when sliced meat with a relatively large amount of fat and rigidity and with a small cutting area used for grilled meat, etc., the sliced meat pieces do not easily adhere to the outer peripheral surface of the rotary transfer body. When the rotary transfer body is suddenly stopped at a predetermined position with a small effect, the stop position may be shifted due to inertia or may be dropped as it is.

In addition, it is not preferable to stop the rotating transfer body each time the sliced meat piece is cut out, because it gives a shock to the drive system of the rotating transfer body.
JP 2003-48192 A

  In consideration of the above-mentioned problems in the prior art, the present invention can be easily peeled off by the transfer piece even when the needle tip is pressed deeply into the sliced meat piece and pressed against the needle-like protrusion. Even sliced meat pieces that are difficult to follow along the protrusions can be reversed and transferred accurately and reliably at a predetermined position, and do not give a shock to the drive system of the rotary transfer body. An object of the present invention is to provide a device for transferring sliced meat pieces in a meat slicer.

  The meat box is moved upward with respect to the cutter in a fixed position, and the meat placed on the meat box is sliced, and a number of needle-like protrusions on the outer periphery are located immediately below the cutter. A rotary transfer body is formed, and the rotary transfer body peels off the received sliced meat piece while rotating in the upward movement direction of the meat box, and a comb-like transfer piece that is reversed and transferred to the carry-out conveyor. In the slice meat piece transfer apparatus provided, a slice meat piece transfer apparatus configured to swing the transfer piece at a predetermined timing related to the upward movement of the meat box while continuously rotating the rotary transfer body. .

  Further, the slice meat piece transfer device is configured such that the slice meat piece to be reversed and transferred can be selected to be folded in two or expanded by changing the timing of swinging the transfer piece. .

  While continuously rotating the rotating transfer body that received the sliced meat pieces while rotating in the upward movement direction of the meat box, the transfer piece is swung at a predetermined timing related to the upward movement of the meat box, and the sliced meat pieces are peeled off and carried out. Since it is configured to be reversed and transferred to the conveyor, the following effects can be obtained.

  When the transfer piece peels off the sliced meat piece stabbed in the needle-like protrusion of the rotary transfer body, the rotation of the rotary transfer body rotates so that the direction of the tooth profile forming the needle-like protrusion follows the peeling direction. Compared to the case where the sliced meat piece in the state is stopped and the conventional rotary transfer body is stopped and stopped, it can be easily peeled off. Particularly, as described above, the sliced meat piece is effective in a state where the sliced meat piece is deeply pierced into the needle-like protrusion or a sliced meat piece that is easily broken.

  Conversely, even sliced meat pieces that have rigidity and are difficult to follow along the needle-like projections of the rotary transfer body are reversed by swinging the transfer piece at a predetermined timing during transfer without stopping at a predetermined position as in the past. Since it is transferred, accurate and reliable transfer is possible.

  Since the rotary transfer body does not stop each time a sliced meat piece is cut out as in the prior art, the capacity can be increased by the stop time. In addition, since a shock is not applied to the drive system of the rotary transfer body, a smooth operation can be performed without difficulty.

  Furthermore, by changing the timing at which the transfer piece is swung, it is possible to select either the folded state or the spread state of the sliced meat piece that is reversely transferred onto the carry-out conveyor, so that it can be used properly. .

  The best mode for carrying out the present invention will be described below with reference to the drawings.

  FIG. 1 is a side view of an essential part of an embodiment of the present invention apparatus, FIG. 2 is a perspective view of the same figure, and FIG. 3 shows an example of a transfer state.

  The meat slicer in the present embodiment in which only the main part is displayed is a well-known meat slicer, and the meat box 2 having the delivery conveyor 1 placed in a substantially horizontal state holds the meat M and reciprocates vertically. It is configured to be driven by a servo motor through a crank mechanism (not shown) as possible, and when the meat box 2 moves up (arrow A in FIG. 1), the front end of the meat M is sliced by a cutter described later.

  A cutter is provided close to the front end of the meat box 2. The cutter may be a rotating round blade, but in this embodiment, the cutter is loosely fitted into a guide groove formed on the lower end of the plate-like member 4 attached to the machine body (not shown) in the left-right direction. It is composed of an endless band-shaped band knife 3 whose outer edge is sharply bladed, and is wound around a pair of drums provided on the left and right sides of the machine body (not shown) to rotate at high speed.

  One end faces the cutting edge of the band knife 3 to form a cut-out port of the sliced meat piece m, and the abutment plate 5 that regulates the thickness of the slice that receives the front end surface portion of the meat M extends over the entire width of the delivery conveyor 1. Is provided.

The plate 5 is appropriately moved and adjusted in the delivery direction of the meat M together with the later-described rotary transfer-like body, the transfer piece, and the carry-out conveyor to determine the slice thickness.
In addition, a plurality of grooves are formed at the end of the abutting plate 5 facing the blade of the band knife 3 so that the tip of the needle-like protrusion created in the rotary transfer body can enter.

  A rotary transfer body 6 for receiving and transferring the sliced meat piece m to be cut out is provided immediately below the cutout opening (right side in FIG. 1). As the rotary transfer body in this embodiment, a large number of needle-like protrusions are provided on the outer periphery. It is set as the structure which created the row | line | column which has A in the width direction, maintaining the space | interval in the width direction.

  The rotary transfer body 6 is not limited to a rotary body, and may be configured by, for example, a row of endless belts such as chains in which needle-like protrusions are established, with a gap in the width direction.

  The rotary transfer body 6 includes a plurality of discs 6a, each having a large number of needle-like protrusions formed on the outer periphery, and a distance collar (which can secure a predetermined interval at which a later-described transfer piece 8 can protrude and retract between the discs 6a. A hole drilled in the center of the disk 6a is sequentially inserted through the support shaft 6b with a cylindrical shape sandwiched between them (not shown), and is assembled into a cylindrical shape. .

  The rotary transfer body 6 configured as described above has at least a width dimension over the entire width of the delivery conveyor 1, and is disposed immediately below the band knife 3 so that the support shaft 6b is orthogonal to the delivery direction. .

  Although not shown, both ends of the support shaft 6b are rotatably supported by the machine body. A transmission motor 7 is connected to one end of the support shaft 6b, and the rotary transfer body 6 can be continuously rotated in the same direction as the upward movement direction A of the meat box 2 (the direction of arrow B in FIG. 1).

  The rotational speed of the rotary transfer body 6 is set in relation to the upward movement speed of the meat box 2. In order to receive the sliced slice m to be cut out in an unfolded state, the upward movement speed of the tip of the meat box 2 and the outer peripheral speed of the rotary transfer body 6 are synchronized or the outer peripheral speed of the rotary transfer body 6 is increased. It is preferable to make it slightly larger so that the sliced meat piece m is received in a tensile manner.

  When the meat box 2 is reciprocated via a crank device (not shown) as in the present embodiment, the movement speed changes in a sine wave shape, so that it corresponds to the vicinity of the average value of the upward movement speed near the meat M to be sliced. Thus, the outer peripheral speed of the rotary transfer body 6 is set.

  The transfer piece 8 is constructed by implanting a comb bar 8b made of a plurality of fine rods in a comb shape on a horizontal bar 8a having a length that can cover the entire width of the cutout opening of the meat M, and the comb bar 8b. A delivery position on the carry-out conveyor 9 from a standby state (a state in which the comb bar 8b in FIG. 1 is indicated by a solid line) immersed in an interval formed between a plurality of disks 6a. In the state in which the comb bar 8b is in a virtual line display state, it can be swung around the horizontal bar 8a (arrows C and D in FIG. 1).

  The carry-out conveyor 9 receives the sliced meat pieces m that are provided close to the rotary transfer body 6 at the starting end and reversely transferred by the transfer piece 8 and takes them out of the machine.

  A servo motor 10 is connected to the shaft end of the horizontal bar 8a. When the comb piece 8b... Of the transfer piece 8 is in a standby state, the sliced meat piece m being transferred by the continuously rotating rotary transfer body 6 passes through the vicinity immediately above the comb piece 8b. Is started, the transfer piece 8 is swung, and the sliced meat piece m is peeled off from the back side and transferred to the carry-out conveyor 9 and delivered.

  The timing for swinging the transfer piece 8 is set as follows. That is, the elapsed time from when the meat box 2 starts to start moving up to when the sliced slice m cut out is transferred by the rotary transfer body 6 and reaches a predetermined position near the transfer piece 8 is calculated. Then, the servo motor 10 is activated in accordance with the set time to swing the transfer piece 8.

  As shown in FIG. 1, the transfer piece 8 is shaken in accordance with the timing when the vicinity of the center of the sliced meat piece m transferred by the rotary transfer body 6 reaches the open end of the comb bar 8b constituting the waiting transfer piece 8. If set so as to be moved, the sliced meat piece m can be reversed and transferred in a state of being folded in two across the open end of the comb barb 8b.

  Further, the length dimension in the cutting direction of the meat M is detected using a known technique, and the elapsed time is changed based on the detected numerical value to set the timing at which the transfer piece 8 swings. It is also possible to control so that the position (bending position) where the sliced meat piece straddles the open end of... Is always constant regardless of the size of the meat M.

  Further, as shown in FIG. 3, the transfer piece 8 is swung at the timing at which the combs 8b of the transfer piece 8 on standby and the length dimension in the cutting direction of the sliced meat piece m are superposed, so that the sliced meat piece m It can also be reversed and transferred to the carry-out conveyor 9 in an unfolded state.

In this case, FIG. 3 shows a state immediately before the transfer piece 8 swings at the timing when the first half of the sliced meat piece m is separated from the outer periphery of the rotary transfer body 6 and rests on the transfer piece 8 on standby. Has been.
Further, if the elapsed time is lengthened and the timing at which the transfer piece 8 swings is delayed, the sliced meat piece m is transferred onto the transfer piece 8, but this state is when the elapsed time is the longest.

  A servo motor 10 for swinging the transfer piece 8 is mounted on the tip of a rod of an air cylinder 11 with a guide mounted on a machine frame (not shown), and the transfer piece 8 is a delivery position facing the carry-out conveyor 9. In FIG. 1, the sliced meat piece m is retreated (arrow E) to the retreated position indicated by the phantom line in FIG.

  In addition, when the above-mentioned slice meat piece m is reversely transferred in a spread state, the retreating operation (arrow E) of the transfer piece 8 can be omitted, and the efficiency is increased accordingly.

  Although not shown, the servo motor 10 is replaced with a rotary air cylinder or a telescopic air cylinder whose one end is connected to an operating arm extending radially from the end of the horizontal shaft 8a, and the solenoid valve is set at the timing set as described above. It can also be configured to swing the transfer piece 8 under control.

  Although a series of controls as described above are performed electrically, a specific control method can be performed by using ordinary conventional means, and thus detailed description thereof is omitted.
