In this case, when the passage sensor detects the passage of the flower-collected object, the electric motor is activated to operate the binding operation unit, and a plurality of flower-collected objects are bundled together.

Further, Patent Document 2 shows an example of a specific configuration of the binding machine according to the prior art.

Japanese Patent No. 3445127 Japanese Unexamined Patent Publication No. 7-170834

However, in the prior art, the binding is caused by the passage sensor, the binding string of the binding machine (see FIG. 10 of Patent Document 1), or the like coming into contact with the bound object during the binding operation of the bound object by the binding machine. An object may tilt and its binding position may deviate from the intended position. Further, when the inclination of the bound object is large, it may not be possible to bind well. The problem becomes more pronounced when the individual weights of the objects to be bound are light, such as garlic chives and leeks.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a transport device with a binding machine having high binding stability.

In the transport device with a binding machine according to the present invention, a plurality of support portions for supporting a plurality of elongated bundled objects and a bundled object supported by the support portions are sequentially transported along a transport path. A detection sensor that detects that the binding operation start position has been reached and a binding machine that performs a binding operation of the bound object based on the detection result of the detection sensor are provided, and the support portion includes a cover on the support portion. It is characterized in that a movement restricting unit for restricting the movement of the bound object to the upstream side in the transport direction during the binding operation by the binding machine is provided.

Here, the "binding operation" includes a series of operations from the detection operation of detecting that the object to be bound has reached the binding operation start position to the end of the actual binding. Therefore, "during the binding operation by the binding machine" refers to a series of operations from the time when the bound object reaches the binding operation start position to the end of the binding operation.

According to this aspect, movement to the upstream side in the transport direction is restricted during the binding operation by the binding machine, so even if a force is applied to the bound object toward the upstream side in the transport direction during this binding operation. , Stable binding operation can be realized.

According to the present invention, it is possible to prevent the object to be bound from tilting during the binding operation, so that a stable binding operation can be realized.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. The following description of preferred embodiments is merely exemplary and is not intended to limit the invention, its scope of application or its use.

-Structure of transport device with binding machine-
First, the overall configuration of the transfer device 1 with a binding machine (hereinafter, simply referred to as the transfer device 1) according to the present embodiment will be described in detail with reference to the drawings. As shown in FIG. 1, the transport device 1 includes a device main body 3 surrounded by a rectangular box-shaped frame 30, a conveyor-type transport path 4, and a plurality of supports that are sequentially transported along the transport path 4. It is detected that the assembly 10 (hereinafter, may be simply referred to as the assembly 10) of the portion 5 and the bound object 11 (see FIG. 5) supported by the support portion 5 has reached a predetermined binding operation start position. It includes a detection sensor 6 and a binding machine 7 that operates based on the detection result of the aggregate 10 by the detection sensor 6. Caster 39s are attached to the lower front, rear, left and right corners of the transport device 1.

The bound object 11 has an elongated shape and is, for example, a plant or dried seafood. The plant is, for example, a flower such as chrysanthemum or a vegetable such as garlic chives or leeks, and the dried seafood is, for example, kelp or the like. However, the object to be bound 11 is not limited to the above-exemplified one, and if it has an elongated shape, it can be bound by using the transport device 1 of the present embodiment. Also, plants and dried seafood are not limited to the above. In the present embodiment, for convenience of explanation, the direction in which the aggregate 10 is conveyed is referred to as a transfer direction. Further, the front side (upstream side) in the transport direction may be referred to as the front, and the back side (downstream side) in the transport direction may be referred to as the rear. Further, the tip end portion 11a (see FIG. 5) side of the bound object 11 (aggregate 10) to be conveyed is referred to as the left, and the base end portion 11b (see FIG. 5) side of the bound object 11 (aggregate 10) is referred to as the left side. Called right. The bound object 11 is referred to as a tip and a base end for convenience of explanation, but the tip and the base end may be reversed.

As shown in FIG. 2, the frame body 30 includes a pair of left and right upper frames 31, 31 extending in the front-rear direction at the upper corners of both left and right ends. Bearings 36, 36, ... Are attached to both front and rear ends of each upper frame 31, and a pair of front and rear chain drive shafts 37, 37 are bridged between the corresponding bearings 36, 36, ... In the left-right direction. Is supported by the shaft. Further, three sprockets 38, 38, 38 are attached to the chain drive shaft 37, respectively, separated from each other in the left-right direction. More specifically, the sprockets 38 and 38 are fixed to the chain drive shaft 37 in a state of being fitted at two positions corresponding to the positions of the tip side support portion 51 described later on both sides in the left-right direction. Further, the sprocket 38 is fixed to the chain drive shaft 37 in a state where the sprocket 38 is fitted at one position corresponding to the position at the center in the left-right direction of the base end side support portion 52 described later. The fixing position of the sprocket 38 is not limited to the above-mentioned place, and may be attached to a place different from the above-mentioned place, and the number of the sprocket 38 may be different. A main body motor (not shown) for driving each chain drive shaft 37 is housed in the frame body 30. A switchboard 8 is provided on the outside of the frame.

The transport path 4 includes three endless chains 41, 41, 41 laid between the corresponding sprockets 38, 38, .... The support portion 5 has a function of supporting the aggregate 10 transported along the transport path 4. Specifically, the support portion 5 includes a tip side support portion 51 (see FIG. 5) as one end side support portion for supporting the tip end side of the bound object 11 (aggregate 10) and the bound object 11 (aggregate). It has a base end side support portion 52 (see FIG. 5) as a support portion on the other end side that supports the base end side of the body 10), and a movement restricting portion 53.

A plurality of support portions 5 are attached to the outside of the endless chain 41 in the traveling direction so as to be separated from each other at a predetermined pitch with respect to the traveling direction (front-rear direction). The distance between the support portions 5 adjacent to each other in the front-rear direction is based on, for example, the working speed of the worker, the processing speed (working speed) of equipment such as a packaging machine (not shown) installed after the transport device 1, and the like. Can be set arbitrarily.

The two endless chains 41 on the left side are provided with mounting portions (not shown) for mounting the tip side support portions 51 at positions corresponding to the tip end side support portions 51. Similarly, the rightmost endless chain 41 is provided with an attachment portion (not shown) for attaching each proximal end side support portion 52 at a position corresponding to each proximal end side support portion 52. The configuration of the mounting portion (not shown) is not particularly limited, but for example, a configuration in which a mounting plate having screw holes formed through in the vertical direction is fixed to the endless chain 41 by welding or the like can be adopted.

Then, the tip end side support portion 51 and the base end side support portion 52 are attached and fixed to each attachment portion. Further, as will be described in detail later, the movement restricting portion 53 is screwed and fixed to the base end side fall prevention plate 92 arranged between the base end side support portions 52 and 52 adjacent in the front-rear direction. .. Here, the lengths of the three endless chains 41, 41, 41 are aligned. That is, it is configured to rotate synchronously. In other words, the distal end side supporting portion 51, the proximal end side supporting portion 52, and the movement restricting portion 53, which form each of the supporting portions 5, are configured to enable synchronous transportation, respectively, in the traveling direction of the endless chain 41. Transported synchronously. In this way, the endless chain 41 is adopted for the transport path 4, and the tip end side support portion 51, the base end side support portion 52, and the movement restricting portion 53 are fixed to the endless chain 41 so as to rotate. The side support portion 51 and the proximal end side support portion 52 can be rotated in synchronization with each other. For example, when a belt type or rubber cord type transport path is adopted, when the lengths of the tip side support portion 51 and the base end side support portion 52 in the left-right direction are different, the tip side support portion 51 and the tip side support portion 51 are used. Although it becomes difficult to synchronize the rotation with the base end side support portion 52, the occurrence of such a synchronization drive problem can be prevented by adopting the endless chain 41.

Further, the tip end side support portion 51 and the base end side support portion 52 are arranged so as to be separated from each other in the left-right direction, and the assembly 10 is bound by the binding machine 7 at an intermediate position in the left-right direction of both support portions 51 and 52. Is configured to allow

Specifically, the tip-side support portion 51 rises from a mounting portion 51a for the operator to mount the aggregate 10 of the bound objects 11 and both ends of the mounting portion 51a in the front-rear direction (transportation direction). It is provided with a side wall portion 51b. The length of the tip-side support portion 51 is set to be longer than the length of the bound object 11 to be conveyed. The mounting portion 51a is a flat plate that follows a horizontal plane. As shown in FIG. 1, the side wall portion 51b is raised at an angle of about 30 degrees with respect to the horizontal plane (the surface of the mounting portion 51a). However, the rising angle of the side wall portion 51b with respect to the horizontal plane is not limited to the above, and may be set gently, or the rising angle may be raised to about 90 degrees with respect to the horizontal plane. However, as shown in FIGS. 1 and 5, the rising angle is set with respect to the horizontal plane from the viewpoint of ensuring workability by the operator and preventing the placed bound object 11 from coming apart. It is desirable that the inclination is set to about 30 to 45 degrees.

The base end side support portion 52 has a function of supporting the right side (base end side) of the binding position, and in the present embodiment, it is formed of a flat plate along a horizontal plane. In the present embodiment, since one end portion (for example, the base end portion) of the assembly 10 is bound, most of the bound object 11 is supported by the distal end side support portion 51. It has such a configuration. Therefore, when the binding position is an intermediate position (near the center) in the left-right direction of the object to be bound 11, the configuration may be the same as that of the tip-side support portion 51.

If the bundled object 11 (aggregate 10) can be sufficiently supported only by the tip end side support portion 51, the base end side support portion 52 may not be provided. However, when binding with the binding machine 7, a vertical force is applied to the bound object 11 (aggregate 10), so that the base end side support portion 52 is bound from the viewpoint of binding at a more reliable position and more reliably. It is desirable to provide.

A rectangular flat plate-shaped fall prevention plate 91 extending in the horizontal direction is provided between the two adjacent tip-side support portions 51, 51 from the viewpoint of preventing the bound object 11 from falling. In FIG. 1, the length of the fall prevention plate 91 in the left-right direction is aligned with the tip-side support portion 51. However, if the above-mentioned fall prevention object is achieved, it is not always necessary to make the lengths of the tip side support portion 51 and the fall prevention plate 91 in the left-right direction uniform. Further, the width of the fall prevention plate 91 in the front-rear direction is not particularly limited, but since the fall prevention plate 91 also rotates according to the rotation of the endless chain 41, the width is set so as not to interfere with the rotation. Is desirable.

Similarly, a rectangular flat plate-shaped fall prevention plate 92 is provided between the two adjacent base end side support portions 52, 52. In this embodiment, an example in which a fall prevention plate 92 having the same shape as the base end side support portion 52 is provided is shown. It does not necessarily have to have the same shape, but there is an advantage in using the same parts from the viewpoint of cost reduction and workability improvement.

The movement restricting portion 53 is erected upward from the fall prevention plate 92 at the front end portion of the fall prevention plate 92 adjacent to the rear side of the base end side support portion 52. Specifically, as shown in FIGS. 3 to 5, the movement restricting portion 53 includes a flat plate-shaped fixing portion 53a through which a screw hole for screwing and fixing to the fall prevention plate 92 is formed, and a fixing portion 53a. It is an L-shaped plate-shaped body composed of an upright portion 53b folded upward from the screw. The movement restricting unit 53 is configured to restrict the object to be bound 11 placed on the support portion 5 from moving to the rear side (upstream side in the transport direction) during the binding operation by the binding machine 7. The specific shape is not limited. For example, the movement restricting portion is a columnar rod-shaped body, and the rod-shaped body is screwed and fixed to a screw hole formed in a fall prevention plate 92 adjacent to the rear side of the base end side support portion 52. May be adopted.

The detection sensor 6 is supported by the support portion 5 at a binding operation start position as a position for starting the binding operation of the assembly 10 by the binding machine 7, for example, a predetermined position before the bound object 11 comes into contact with the binding string 72. It has a function of detecting that the bound object 11 (aggregate 10) has arrived. FIG. 5 shows an example in which the detection sensor 6 is a contact type sensor attached to the binding machine 7. Specifically, the detection sensor 6 is attached to a sensor mounting portion 73 extending downward from a portion outside FIG. 5 of the main body 70 of the binding machine 7, and rotates in the front-rear direction with the sensor mounting portion 73 as a fulcrum. It has a work piece 61 that is supported as possible. Then, the actuating piece 61 is configured to be able to detect that the object to be bound 11 has been conveyed to the binding operation start position. The binding operation start position is, for example, a position where the needle of the binding machine 7 is started to operate, and the assembly 10 is conveyed to a position where the front end portion of the assembly 10 comes into contact with the binding string 72 during the binding operation. Is. The detection sensor 6 is not limited to the contact type sensor. For example, a non-contact type sensor using infrared rays may be used.

The binding machine 7 has a main body 70 provided on the work table 71. The workbench 71 is vertically oriented from a needle attached to the main body 70 (not shown in FIG. 5) toward a knotterville-type knot mechanism (not shown) installed under the workbench 71. A binding string 72 such as a rubber string or tape is inserted. In the binding machine 7, when the detection sensor 6 detects that the object to be bound 11 has arrived at a position (binding operation start position) before contacting the binding string 72, the needle moves based on the detection result. It is configured so that the assembly 10 can be bound by the binding string 72 by operating in the vertical direction and the knotting mechanism. Since the specific configuration of the binding machine 7 is the same as that of the prior art (for example, FIG. 10 of Patent Document 1 or Patent Document 2), detailed description thereof will be omitted.

-Operation of transport device-
The operation of the transport device 1 will be specifically described with reference to FIGS. 1 and 5.

First, when the main body motor of the transport device 1 is driven, the endless chains 41, 41, 41 are driven and rotated. Then, the aggregate 10 of the bound objects 11 is sequentially placed on the support portion 5 by the operator on the device front side of the transport device 1. The support portion 5 on which the aggregate 10 is placed is sequentially transported along the transport path 4 and arrives at a position as shown in FIG. After that, the actuating piece 61 of the detection sensor 6 is rotated toward the front side by the object to be bound 11, and when the rotation angle becomes equal to or more than a predetermined value, the binding machine 7 is activated and the assembly 10 is formed by the binding string 72. Be united. After that, the bundled aggregate 10 is transported to the rear end portion of the transport device 1, and is delivered to, for example, a packaging machine or a transport device (not shown) installed at the rear end of the transport device 1.

In this transport process and the binding process, for example, when the operating piece 61 of the detection sensor 6 or the binding string 72 of the binding machine 7 hits the bound object 11, the force of the bound object 11 toward the front side (upstream side in the transport direction). May receive. Even in such a case, in the present embodiment, since the movement restricting unit 53 is provided at a position that restricts the movement of the bound object 11 to the front side (upstream side in the transport direction), the bound object 11 is transported. It is possible to prevent tilting with respect to the direction. As a result, the transport device 1 according to the present embodiment can realize a binding operation at an accurate binding position and a reliable binding operation.

<Other Embodiments>
In the above embodiment, the movement restricting portion 53 is assumed to be erected on the fall prevention plate 92 adjacent to the rear side of the base end side support portion 52, but the present invention is not limited to this. For example, when the fall prevention plate 92 is not provided, the movement restricting unit 53 is attached to the endless chain 41 at a position corresponding to the above embodiment, and is configured to stand upward from that position. You may. Further, regarding the tip side support portion 51, the length of the mounting portion 51a is longer than that of the side wall portion 51b, and the mounting portion 51a protrudes at the right end portion (base end side). The movement restricting portion 53 may be erected at the right rear end portion (for example, the corner portion on the right rear side) of the projecting mounting portion 51a. In this case, the fall prevention plate 92 adjacent to the rear side of the base end side support portion 52 may be provided or may be omitted.

Further, in the above embodiment, the conveyor type transport path 4 is driven and rotated by the endless chain 41, but the present invention is not limited to this. For example, the support portion 5 may be attached and fixed to the belt type conveyor. However, as described above, adopting the endless chain 41 has an advantage that it is easier to synchronize between the tip end side support portion 51 and the base end side support portion 52. Further, for example, the tip end side support portion 51 may be driven and rotated by the endless chain 41, while the base end side support portion 52 may be configured by a rubber belt. In this case as well, the movement restricting portion 53 may be provided on the tip end side support portion 51 or may be provided on the base end side support portion 52. Even in such a configuration, the same effect as that of the above embodiment can be obtained.

Further, in the above embodiment, the movement restricting portion 53 shows an example in which the movement restricting portion 53 is erected on the front side (upstream side portion in the transport direction) of the mounting portion 51a of the tip side support portion 51. However, the present invention is not limited to this, and the movement restricting portion 53 may be erected at an intermediate position closer to the upstream in the transport direction of the mounting portion 51a. However, from the viewpoint of enhancing the ease of placing the bound object 11 by the operator, it is desirable that the movement restricting portion 53 is erected on the front side of the mounting portion 51a of the tip side support portion 51.

The transport device with a binding machine according to the present invention has high binding stability and is extremely useful as a transport device with a binding machine for elongated bound objects, particularly for vegetables such as garlic and green onions or for dried seafood.
