Description

[Technical Field]

[0001] The present invention relates to a hanging device for hanging sausages on a rod, and more particularly to a hanging device for hanging a chain of sausages, which are casings having a predetermined length filled with ingredients, on a rod. [Background technology]

[0002] In a sausage production line, a sausage stuffing machine first stuffs raw materials into a casing of a predetermined length, then twists the casing to form a chain of sausages.The chain of sausages is then hung on a rod by a rod hanging device, and then sent to the subsequent heating and smoking processes.

[0003] One example of a rod-hanging device used to hang a chain of sausages on a rod is one that uses hooks attached at predetermined intervals to an endless chain, which is an endless loop, to form loops of the chain of sausages, and then inserts the rod through the loops to hang the sausages on the rod.

[0004] Patent Document 1 discloses such a rod-hanging device that can transfer a whole rod's worth of chained sausages hung from a hook simply by moving the cantilevered rod horizontally. This rod-hanging device has hooks that rotate around a substantially horizontal axis attached at regular intervals to an endless circulator. The chained sausages are hung on the hooks so that they form loops, and by rotating the hooks, the chained sausages hanging from the hooks can be transferred to a cantilevered rod that has been inserted into the loops.

[0005] Furthermore, a rod hanging device for hanging a chain of sausages on a rod that is held at both ends is disclosed in Patent Document 2. In this rod hanging device, the front part of the rod that is inserted into the loop of the chain of sausages is supported by a rod front support member, and the rear part of the rod is supported by a rod rear support member. The rod rear support member is provided on a second endless circulating body that moves in the same direction as the first endless circulating body to which the hook portion is attached. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Japanese Patent Application Publication No. 2019-097539 [Patent Document 2] Japanese Patent Application Laid-Open No. 2006-197935 Summary of the Invention [Problem to be solved by the invention]

[0007] However, in the case of a rod-hanging device such as that described in Patent Document 1, which transfers a chain of sausages from a hook portion to a cantilevered rod, the cantilevered rod may cause the rod to bend due to the weight of the chain of sausages when they are hung. If the rod bends, the chain of sausages may fall off. A curved rod also makes it difficult to insert the loops of the chain of sausages, and the tip of the rod may hit the chain of sausages, damaging them. Furthermore, when a curved rod is sent to the subsequent heating or smoking process, there is a risk that the rod may fall off the cart or that the chain of sausages may be unevenly gathered near the center of the rod. Even if the rod does not bend, its cantilevered state causes the rod to sway, making it difficult to hang the chain of sausages in the correct position. Furthermore, when the rod shakes, the chain of sausages also shakes, which can cause the twisted parts of the chain of sausages to untwist, make the casing more likely to break, or cause the appearance to become distorted, resulting in a defective product.

[0008] Furthermore, the device for hanging on a rod in Patent Document 1 is structured so that the chain of sausages is transferred from the hook to the rod by the coordinated action of the hook and the guide groove of the transfer execution means, and so the chain of sausages can be hung at specific positions and at specific intervals determined by the guide groove. Therefore, it was difficult to change the positions and intervals at which the chain of sausages was hung on the rod to match the length of the casing.

[0009] Furthermore, in the device for hanging sausages on a rod in Patent Document 2, the rod is held on both sides and the chain of sausages is hung, so there is no risk of the rod bending or swaying as with devices for hanging sausages on a rod that hangs them on one side. However, the position and interval at which the chain of sausages is hung on the rod cannot be changed to match the length of the casing.

[0010] The length of the casings is not constant, and the number of loops of the sausage chain hung on one rod varies depending on the length of the casing. With conventional technology, where the hanging position cannot be adjusted, if the sausage chain is hung at a specific position and at specific intervals, there is a risk that the sausage chain will be unevenly hung on one rod if the casings are short. This results in uneven gaps between the sausage chains hung on multiple rods mounted on a cart. Such uneven gaps could result in uneven smoking in the subsequent smoking process, resulting in a defective product. This required the laborious task of manually rehanging the sausages.

[0011] Therefore, there has been a demand for the development of a rod-hanging device that can change the position and spacing at which a chain of sausages is hung on a rod according to the length of the casings, without causing the rod to sway or bend.

[0012] SUMMARY OF THE INVENTION In view of the above circumstances, the present invention provides a rod-hanging device that can change the position and interval at which a chain of sausages is hung on a rod that is stably held, depending on the length of the casings. [Means for solving the problem]

[0013] In order to achieve the above-mentioned object of the present invention, the rod hanging device of the present invention comprises a hook transport unit having a plurality of swivelable hooks arranged at a predetermined interval, which transports the plurality of swivel hooks at a predetermined speed, the hook transport unit being configured so that a loop of sausage chains is formed on each of the plurality of swivel hooks, and the hook transport unit is configured so that by rotating each swivel hook, the loop of sausage chains hung on the swivel hooks can be dropped onto a rod through which the loop is passed; and rod holding units for holding both ends of the rod on which the chain of sausages hung on the plurality of swivel hooks of the hook transport unit is hung, the end of the rod farther from the direction of transport of the plurality of swivel hooks. The device has a fixed arm that holds the vicinity of the end of the rod closer to the conveying direction of the multiple swivel hooks, and a pair of operating arms that hold the vicinity of the end of the rod closer to the conveying direction of the multiple swivel hooks, and the pair of operating arms alternately perform operations of holding the rod and avoiding the loops of the chain of sausages in order to sequentially insert the loops of the chain of sausages hung from the multiple swivel hooks onto the rod, and a swivel unit that is configured to sequentially swivel the multiple swivel hooks at each predetermined swivel position while moving in the opposite direction to the conveying direction of the multiple swivel hooks of the hook conveying unit so that the loops of the chain of sausages hung on each swivel hook of the hook conveying unit fall to predetermined positions on the rod at predetermined intervals.

[0014] Here, the hook conveying unit has an endless circulating body configured to be able to move on an elliptical orbit, and each swivel hook of the hook conveying unit is connected to the endless circulating body and comprises a hook base having a swivel shaft, a bearing for rotatably supporting the swivel shaft, a sausage hanging portion formed below the bearing for suspending a loop of chain-like sausages, and a swivel imparting receiving portion formed above the bearing against which the swivel imparting portion abuts.

[0015] Furthermore, the rotation imparting unit may wait at a predetermined rotation imparting position, and rotate the rotation hooks by the rotation imparting receiving units of the multiple rotation hooks transported at a predetermined speed by the hook transport unit abutting against the rotation imparting unit.

[0016] In addition, the swivel imparting section has an abutment arm that abuts against the swivel imparting receiving section, and the abutment arm extends to abut against each swivel imparting receiving section when the swivel imparting section moves in the opposite direction to the conveying direction of the multiple swivel hooks of the hook conveying section, and contracts so as not to abut against the swivel imparting receiving section when the swivel imparting section returns to the conveying direction of the multiple swivel hooks of the hook conveying section after the swivel imparting.

[0017] Furthermore, the device may have a control unit that presets the number and spacing of loops of chained sausages to be hung on one rod based on a predetermined length of the casing, and the control unit may control the conveying speed of the hook conveying unit, the operation of the pair of operating arms of the rod holding unit, and the rotation operation of the rotation imparting unit based on the preset number and spacing of loops of chained sausages. [Effects of the Invention]

[0018] The apparatus for hanging sausages on a rod of the present invention has the advantage that the position and interval at which the chain of sausages is hung on the rod that is stably held can be changed according to the length of the casings. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0020] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a schematic top view illustrating the overall configuration of the rod-hanging device of the present invention. As shown in the figure, the rod-hanging device of the present invention is mainly composed of a hook transport unit 10, a rod holding unit 20, and a swivel imparting unit 30. The rod-hanging device of the present invention is used to hang a chain of sausages 2, which are formed by stuffing ingredients into a casing 1 of a predetermined length using a sausage stuffing machine, on a rod 3. Here, the chain of sausages 2 refers to a casing 1 filled with ingredients, twisted at regular intervals, and linked together in a chain. The rod 3 on which the chain of sausages 2 is hung can be removed from the rod holding unit 20 and sent to a subsequent smoking process or the like.

[0021] The casing 1 may be a natural casing made from the intestines of pigs, sheep, etc., or an artificial casing made from collagen, etc. In the case of natural casings, the length of the casing cannot be known in advance, but in the case of artificial casings, the length of the casing can be known in advance. Either natural or artificial casing is acceptable, but as will be described later, the hanging device of the present invention can change the position and spacing at which the linked sausages 2 are hung on the rod 3 depending on the length of the casing 1. Therefore, in the case of artificial casings, the length of the casing 1 can be known in advance, so the position and spacing can be specified in advance.

[0022] The hook transport unit 10 transports a plurality of swivel hooks 11 at a predetermined speed. The plurality of swivel hooks 11 are arranged at predetermined intervals. The hook transport unit 10 is configured to rotate each swivel hook 11 so that the loops of the chain of sausages 2 suspended from the swivel hooks 11 can be dropped onto the rod 3 through which the loops are passed.

[0023] The hook conveying unit 10 has an endless circulating body 12. As shown in FIG. 1, the endless circulating body 12 is configured to be movable on an elliptical orbit. The endless circulating body 12 may be, for example, a chain loop or a belt loop. The endless circulating body 12 is configured to move from a position where a chain of sausages 2 is hung from a plurality of swivel hooks 11 to a position where the chain of sausages 2 is dropped onto a rod 3, and then return to a position where the chain of sausages 2 is hung again after dropping the chain of sausages 2 empty. The rod 3 is disposed parallel to the endless circulating body 12, and the swivel hook 11 is conveyed along the rod 3. The conveyance of the swivel hook 11 of the hook conveying unit 10 may be intermittent. When the conveyance of the swivel hook 11 is temporarily stopped, the chain of sausages 2 may be sequentially hung from the sausage stuffing device onto the swivel hook 11. In addition, the transport of the swivel hook of the hook transport unit 10 is not necessarily limited to being performed intermittently, but may be performed continuously, with the chain of sausages 2 being hung sequentially on the swivel hook 11 in accordance with the transport operation.

[0024] The specific configuration of the hook transport unit 10 will be described using Figure 2. Figure 2 is a schematic side view for explaining the details of the rod hanging device of the present invention. In the figure, parts with the same reference numerals as in Figure 1 represent the same objects. A plurality of swivel hooks 11 are connected at equal intervals to the endless circulating body 12 and are transported along the elliptical orbit of the endless circulating body 12. Each of the plurality of swivel hooks 11 is suspended so that one loop 2a of the chain of sausages 2 is formed. The loop 2a is a loop formed by linking a plurality of sausages in a chain, and for example, one loop 2a is formed by four sausages as shown in the figure. The number of sausages that make up the loop is not particularly limited to the example shown in the figure.

[0025] As shown in Figure 2, the swivel hook 11 comprises a hook base 13, a bearing 14, a sausage hanging portion 15, and a swivel receiving portion 16. The hook base 13 is connected to the endless circulator 12. The hook base 13 has a swivel shaft 13a. The swivel hook 11 is configured to be swivelable around the swivel shaft 13a. The bearing 14 rotatably supports the swivel shaft 13a. The sausage hanging portion 15 is formed below the bearing 14. The sausage hanging portion 15 is a portion that suspends the loops 2a of the chain of sausages 2. The swivel receiving portion 16 is formed above the bearing 14. The swivel receiving portion 16 is a portion that abuts the swivel providing portion 30, which will be described later. The swivel hook 11 may be any type in which the swivel receiving portion 16 and the sausage hanging portion 15 are integrally formed above and below the bearing 14 of the hook base 13. The weight balance between the sausage hanging portion 15 and the swivel receiving portion 16 may be adjusted so that the sausage hanging portion 15 is at the bottom when the loop 2a is not suspended. Here, the swivel shaft 13a faces diagonally relative to the pole 3 when viewed from above, and the swivel hook 11 is configured to swivel about the swivel shaft 13a facing diagonally on the pole 3. This makes it possible to prevent the swivel hook 11 from coming into contact with adjacent swivel hooks 11 when swiveled by the swivel providing portion 30 described below.

[0026] The illustrated example shows the sausage hanging part 15 having an L-shape. Specifically, the sausage hanging part 15 has a shape obtained by bending a plate-like body having a certain width into an L-shape so that the loops 2a can be spread laterally so that the twisted parts of the chain of sausages 2 can be hooked and the rod 3 can be inserted through the loops 2a. However, the present invention is not limited to this, and any shape may be used as long as the loops 2a can be hung from the sausage hanging part 15 and can be dropped by rotating.

[0027] Next, the rod holding unit 20 holds both ends of the rod 3 when the chain of sausages 2 suspended from the multiple swivel hooks 11 of the hook transport unit 10 is hung on the rod 3. The rod holding unit 20 has a fixed arm 21 and a pair of operating arms 22. The fixed arm 21 holds the vicinity of the end of the rod 3 on the side farther from the conveying direction of the multiple swivel hooks 11. Here, the side farther from the conveying direction of the swivel hooks 11 is the right side in FIG. 2. In other words, the fixed arm 21 holds the vicinity of the end of the rod 3 on the side where the swivel hooks 11 reach later. The fixed arm 21 may be provided with an appropriate U-shaped groove or the like to hold the rod 3 from below. The pair of operating arms 22 hold the vicinity of the end of the rod 3 on the side closer to the conveying direction of the multiple swivel hooks 11. Here, the side closer to the conveying direction of the swivel hooks 11 is the left side in FIG. 2. That is, the pair of operating arms 22 hold the vicinity of the end of the rod 3 that the swivel hook 11 reaches first. The pair of operating arms 22 alternately perform an operation of holding the rod 3 and an operation of avoiding the loops 2a of the chain of sausages 2, in order to sequentially insert the loops 2a of the chain of sausages 2 suspended from the multiple swivel hooks 11 onto the rod 3. The pair of operating arms 22 may also be provided with an appropriate U-shaped groove or the like in order to hold the rod 3 from below.

[0028] The operation of the pair of actuating arms 22 will be described in detail below with reference to FIG. 3. FIG. 3 is a schematic top view illustrating the operation of the pair of actuating arms of the rod holding unit of the rod hanging device of the present invention. In the figure, parts with the same reference numerals as in FIG. 1 represent the same objects. The chain of sausages 2 is shown partially in cross section. The pair of actuating arms 22 includes an arm 22a and an arm 22b. When holding the rod 3, each arm 22a, 22b of the pair of actuating arms 22 extends from below to support the rod 3 from below, and when avoiding the loop 2a of the chain of sausages 2, the arm lowers and retracts. As shown in FIG. 3(a), the loop 2a of the chain of sausages 2 is transported by the hook transport unit 10 from left to right in the drawing. At this time, the arm 22b of the pair of actuating arms 22 first operates to hold the rod 3. That is, the arm 22b extends below the rod 3 to support the rod 3 from below. Meanwhile, arm 22a operates to avoid the loops 2a of the chain of sausages 2. That is, arm 22a retracts from below rod 3 so as not to hit the loops 2a of the chain of sausages 2 being transported from the left. Then, when the loops 2a of the chain of sausages 2, transported from left to right so as not to hit arm 22a, reach just in front of arm 22b, arm 22a and arm 22b switch places. At this time, as shown in FIG. 3(b), both arms 22a and 22b are operated to temporarily hold the rod 3. Thereafter, as shown in FIG. 3(c), arm 22b operates to avoid the loops 2a of the chain of sausages 2. At this time, arm 22a remains in a state of holding the rod 3. Then, as the loop 2a of the chain of sausages 2 is transported from left to right so as not to hit the arm 22b, when the next loop 2a reaches just in front of the arm 22a, the arms 22a and 22b switch places, but at this time too, as shown in Figure 3(d), both arms 22a and 22b are operated to temporarily hold the rod 3. After that, the arm 22a operates to avoid the loop 2a of the chain of sausages 2, and the state shown in Figure 3(a) is again achieved. By repeating this operation, one of the pair of operating arms 22 always holds the rod 3.

[0029] In this way, the arms 22a, 22b of the pair of operating arms 22 are configured to repeatedly extend and retract operationally at predetermined timing in conjunction with the transport operation of the swivel hook 11 by the hook transport unit 10. Therefore, the rod holding unit 20 can always stably hold both ends of the rod 3 by the operating arms 22 together with the fixed arms 21, while inserting the loops 2a of the chain of sausages 2 onto the rod 3. The distance between the arms 22a, 22b of the pair of operating arms 22 may be configured to be wider than the diameter of the chain of sausages 2 and narrower than the distance between the loops 2a of the chain of sausages 2, i.e., the spacing between the multiple swivel hooks 11.

[0030] Next, the swirl imparting unit 30 will be described. Referring again to FIG. 2, the swirl imparting unit 30 is configured to move in a direction opposite to the conveying direction of the swirl hooks 11 of the hook conveying unit 10, and sequentially rotate each of the swirl hooks 11 at a predetermined swirl imparting position so that the loops 2a of the chain of sausages 2 suspended from each swirl hook 11 of the hook conveying unit 10 are dropped at predetermined positions on the rod 3 at predetermined intervals. As shown in the figure, the swirl hooks 11 with the chain of sausages 2 suspended therefrom are conveyed from left to right in the drawing. At this time, the swirl imparting unit 30 may wait, for example, at a predetermined swirl imparting position, and rotate the swirl hooks 11 when the swirl imparting receivers 16 of the chain of sausages 2 conveyed at a predetermined speed by the hook conveying unit 10 come into contact with the swirl imparting unit 30. The swirl imparting unit 30 may not wait at a predetermined swirl imparting position, but may be operated to move in the opposite direction to the conveying direction of the swirl hook 11 and sequentially abut against each swirl imparting receiver 16 at a predetermined swirl imparting position. In this way, by rotating the swirl hook 11 with the swirl imparting unit 30, it is possible to drop the loops 2a of the chain of sausages 2 hanging from the swirl hook 11 onto the rod 3 through which the loops 2a are inserted.

[0031] At this time, the position at which the swirl imparted by the swirl imparting unit 30 is set can be arbitrarily set so that the loops 2a of the chain of sausages 2 are dropped at a predetermined position on the rod 3 at a predetermined interval. In other words, the position and interval at which the chain of sausages 2 is hung can be changed by the swirl imparting position set by the swirl imparting unit 30, and the loops 2a of the chain of sausages 2 can be hung at a desired position simply by bringing the swirl imparting unit 30 into contact with the swirl imparting receiving unit 16 at the desired hanging position.

[0032] The spacing between the multiple swivel hooks 11 is the maximum spacing among the predetermined spacings between the swivel positions imparted by the swivel imparting unit 30. That is, the spacing at which the widest loops of the chain of sausages 2 are hung is determined by the spacing between the multiple swivel hooks 11. For example, if the hook transport unit 10 transports the swivel hooks 11 intermittently, the spacing at which the widest loops are hung is achieved when all of the loops 2a for one rod are dropped from the swivel hooks 11 while the transport of the swivel hooks 11 is stopped. Therefore, for example, the spacing between the multiple swivel hooks 11 may be adjusted to the spacing at which the widest loops of the chain of sausages 2 to be hung are hung, that is, the spacing at which the minimum number of loops is reached when the casing 1 is short. Furthermore, for example, if the casing 1 is long and the number of loops in one rod of chain of sausages 2 is large, the swivel hooks 11 may be rotated by the swivel imparting unit 30 to drop the loops 2a at swivel imparting positions that are narrower than the spacing between the multiple swivel hooks 11. In this way, by adjusting the relationship between the transport speed of the swivel hook 11 by the hook transport unit 10 and the swivel operation by the swivel unit 30, it is possible to hang the loops 2a of the chain of sausages 2 at equal intervals on a single rod, regardless of the spacing between multiple swivel hooks 11.

[0033] As shown in FIG. 2, the swivel imparting unit 30 may have, for example, an abutment arm 31. The abutment arm 31 abuts against the swivel imparting receiver 16 of the swivel hook 11. The abutment arm 31 may be configured to be extendable and retractable. For example, it may be configured as a cylinder. The abutment arm 31 may be in an extended state so as to abut against each swivel imparting receiver 16 when the swivel imparting unit 30 moves in the direction opposite to the conveying direction of the multiple swivel hooks 11 of the hook conveying unit 10, i.e., from right to left in FIG. 2. The abutment arm 31 may be abutted against the swivel imparting receiver 16 and the swivel hooks 11 may be sequentially rotated at predetermined positions, thereby causing the loops 2a of the chain of sausages 2 hanging from each swivel hook 11 to fall to predetermined positions on the rod 3 at predetermined intervals. The swivel imparting part 30 is not particularly limited to the illustrated example, and may have any shape as long as it can abut against the swivel imparting receiving part 16. In addition, in the illustrated example, the abutment arm 31 abuts against the swivel imparting receiving part 16 in an extended state, but the present invention is not limited to this, and it may be configured so that the swivel imparting receiving part 16 is struck and rotated the moment the swivel hook 11 reaches the swivel imparting position.

[0034] After all the loops 2a of the chain of sausages 2 to be hung on one rod 3 have been dropped onto the rod 3, the contact arm 31 of the swirl imparting unit 30 should be in a contracted state, as shown in Fig. 4. Fig. 4 is a schematic side view for explaining the details of the operation of the swirl imparting unit of the rod hanging device of the present invention. In the figure, parts with the same reference numerals as in Fig. 2 represent the same objects. As shown in Fig. 4, after imparting swirl to the swirl hooks 11 for one rod, when the swirl imparting unit 30 returns in the conveying direction of the multiple swirl hooks 11 of the hook conveying unit 10, i.e., from left to right in the drawing, the contact arm 31 should be contracted so as not to contact the swirl imparting receiver 16. As a result, when the rotation imparting unit 30 moves from right to left in the drawing, the contact arm 31 extends to contact the rotation imparting receiver 16 and rotate the rotation hook 11, and after the rotation is imparted, when the rotation imparting unit 30 returns from left to right in the drawing, the contact arm 31 contracts so as not to contact the rotation imparting receiver 16. The rotation imparting unit 30 then returns to its original position and waits to hang the chain of sausages 2 on the next rod 3.

[0035] In the illustrated example, the contact arm 31 is configured to be extendable and retractable by a cylinder, but the present invention is not limited to this, and any configuration is acceptable as long as it is configured to lower to a position where it can contact the rotation-imparting receiving portion 16 when rotation is imparted, and to rise to a position where it does not contact after rotation is imparted.

[0036] As described above, the apparatus for hanging sausages on a rod of the present invention makes it possible to arbitrarily set the number and spacing of the loops 2a of the chain of sausages 2 to be hung on one rod 3. Therefore, for example, if the length of the casings 1 to be used is known in advance, it is possible to use a control unit 40 that presets the number and spacing of the loops 2a of the chain of sausages 2 to be hung on one rod 3 based on the predetermined length of the casing 1. For example, when the effective length of the rod 3 and the number of loops 2a are input into the control unit 40, the spacing of the loops 2a of the chain of sausages 2 to be hung on one rod 3 is calculated and set in the apparatus for hanging sausages on a rod. Then, the control unit 40 simply controls the conveying speed of the hook conveying unit 10, the operation of the pair of operating arms 22 of the rod holding unit 20, and the rotation operation of the rotation imparting unit 30 based on the set number and spacing of the loops 2a of the chain of sausages 2.

[0037] The fishing rod hanging device of the present invention is not limited to the illustrated example, and various modifications can be made without departing from the spirit of the present invention. For example, in the illustrated example, the endless circulating body moves counterclockwise, but it may move in the opposite direction, and accordingly the swivel hook and swivel imparting part may also be oriented in the opposite direction to that in the illustrated example.
